Vegetarian orang-utans eat world's cutest animal

by Michael Marshall
from the New Scientist
Thanks to Tracy K for the link!




When fruit is scarce, try chomping on a slow loris. That seems to be the strategy adopted by the normally vegetarian orang-utans, which have been spotted knocking the small primates out of trees and killing them with a bite to the head.

Sumatran orang-utans (Pongo abelii) get almost all their nutrients from fruit and other plant products, but there are a few isolated reports of them eating meat (American Journal of Primatology, vol 43, p 159). Madeleine Hardus of the University of Amsterdam in the Netherlands and colleagues have now observed three more cases, bringing the total to nine.

In 2007 Hardus was tracking two orangs in the canopy above her – a female called Yet and her infant Yeni – when Yet abruptly changed direction and approached a slow loris (Nycticebus coucang). She knocked it out of the tree, crashed down to the ground, bit the stunned loris's head, then carried the body back into the tree to eat it. When Yeni begged, she was allowed to share the meat. The great apes each chomped on opposite ends of the dead primate, sharing it between them like lovers might a strand of spaghetti.

Searching through the scientific literature, Hardus found detailed studies of six orang-utan hunts. All stunned their prey before eating it, which Hardus thinks may be to avoid being bitten. Slow lorises are unique among primates in that their saliva is toxic.

All the documented hunts took place when there was little fruit available, which may push the apes to meat-eating, says Hardus.

By contrast, chimpanzees hunt more when fruit is abundant, perhaps because it doesn't matter if they waste energy on a failed hunt.

The sample is unavoidably small, but the data have been thoughtfully analysed, says Richard Wrangham of Harvard University.

Only five individual orang-utans have been observed hunting. Yet has so far been caught in the act four times – three times by Hardus, and once by another researcher – making her the best documented hunter.

In other accounts, the apes stumbled upon their prey, but Yet systematically changed direction and headed straight for the loris, which Hardus says may be because she has learned to smell them. Because a few cases have been documented within a 40-kilometre range, all using the same killing method, she thinks it may be a cultural behaviour, passed from orang-utan to orang-utan.

Madeleine E. Hardus, Adriano R. Lameira, Astri Zulfa, S. Suci Utami Atmoko Han de Vries, Serge A Wich (2012) Behavioral, Ecological, and Evolutionary Aspects of Meat-Eating by Sumatran Orangutans (Pongo abelii). International Journal of Primatology, DOI: 10.1007/s10764-011-9574-z


Abstract
Meat-eating is an important aspect of human evolution, but how meat became a substantial component of the human diet is still poorly understood. Meat-eating in our closest relatives, the great apes, may provide insight into the emergence of this trait, but most existing data are for chimpanzees. We report 3 rare cases of meat-eating of slow lorises, Nycticebus coucang, by 1 Sumatran orangutan mother–infant dyad in Ketambe, Indonesia, to examine how orangutans find slow lorises and share meat. We combine these 3 cases with 2 previous ones to test the hypothesis that slow loris captures by orangutans are seasonal and dependent on fruit availability. We also provide the first (to our knowledge) quantitative data and high-definition video recordings of meat chewing rates by great apes, which we use to estimate the minimum time necessary for a female Australopithecus africanus to reach its daily energy requirements when feeding partially on raw meat. Captures seemed to be opportunistic but orangutans may have used olfactory cues to detect the prey. The mother often rejected meat sharing requests and only the infant initiated meat sharing. Slow loris captures occurred only during low ripe fruit availability, suggesting that meat may represent a filler fallback food for orangutans. Orangutans ate meat more than twice as slowly as chimpanzees (Pan troglodytes), suggesting that group living may function as a meat intake accelerator in hominoids. Using orangutan data as a model, time spent chewing per day would not require an excessive amount of time for our social ancestors (australopithecines and hominids), as long as meat represented no more than a quarter of their diet.

Sex by Numbers


From East Bay Express
Polyamory has gone from being a fringe scene to a veritable subculture. But can having multiple partners ever be widely accepted?

by RACHEL SWAN

Jessica, John, and Kate (not their real names) sat together at Cafe Van Kleef recently, looking more like three long-time friends than three people involved in a love triangle — or, as they'd put it, a love polygonal. Jessica had an arm casually draped around John, who leaned against her contentedly. The two of them met on OKCupid about three years ago, started an email correspondence, and hooked up, for the first time, at a friend's Christmas party — John says they spent most of it making out in the bathroom. They started seeing each other "in a fling capacity," he says, and fell in love against their better interests. John clearly remembers the day it struck him: "We were outside a Virgin Megastore in New York," he recalled, "next to two guys who were laying asphalt. I suddenly turned to her and I was like, 'Hey, I love you.' And she started crying."

About a year into their relationship, Kate entered the picture. She and John had actually known each other for a long time, and John said they'd always had a lot of chemistry. Both were warm and loquacious, identified as 'queer,' and saw themselves as part of the Bay Area's sexual underground. They'd actually met at a drag show. One day, Kate showed up at a music event that John had produced in Oakland's Mosswood Park. (By day, he works as a freelance lighting designer for rock shows.) Kate marched straight up to Jessica. "Full disclosure," she said. "I'm only here to get in your boyfriend's pants."

Weirdly enough, it worked. It turns out Jessica is one of the few people in the world who would take kindly to someone trying to steal her man. Because she doesn't think of it as stealing; it's more like sharing. A good boyfriend shouldn't be squandered on one person, right? At this point, Kate and John have been sleeping together for a full year. They use condoms. John and Jessica are still "primary" partners. Jessica, in the meantime, started seeing three other guys. It's not about getting even, she says; it's about sharing the love. She and Kate are best friends. And Kate has a fiancé of her own.

Confused yet? Jessica explains it this way: "So here's a conventional relationship," she said. "You meet someone, you date, after six months, you use the 'L' word." She paused and glanced over at Kate, who nodded approvingly. "Then you wait for him to ask you to marry him. Then you have a baby."

That isn't what she ever wanted. In fact, since reading Dossie Easton's polyamory primer, The Ethical Slut, in college, Jessica decided that she wanted to impose a cooperative, communal model on her own romantic life, without being a total freak. Although her current relationship with John is her first real foray into polyamory, Jessica said it's something she always wanted. She's certainly not inured to jealousy — no one is, she argues — but she's found ways to sublimate it. And she feels that the returns are well worth the sacrifice, adding that she'll probably never go back to old one-on-one style partnership. "I like being a slut," she insisted.

And Jessica's not alone. Over the past decade, polyamory has gone from being a fringe trend to a bona fide scene to a relationship model that's widespread enough to almost be socially acceptable. The scene has its own canon, which includes texts like The Ethical Slut and Christopher Ryan's Sex at Dawn (co-authored with his partner, Cacilda Jetha). Plus it's got celebrities like alt-weekly sex columnist Dan Savage, who coined the word "monogamish" and turned open relationships into a cause célèbre. He's currently shooting a late-night advice show for MTV. Some would even argue that the proliferation of social networks and dating sites — namely, Facebook and OKCupid — has turned us into a more open culture. The Bay Area in particular, with its long history of free love, its vast network of Burning Man enthusiasts, and its overall progressive ethos, is a natural hotbed for the alternative sex scene. It's a place where avid polyamorists can bring just about anyone into their fold.

Sort of. It turns out that, no matter how successful they've been at negotiating relationships, many polyamorists still have one foot in the closet. And in a world where monogamy is not only well-entrenched but vital to the workings of a property-based society, their scene may always remain marginal.

That realization has caused many "ethical sluts" to treat open relationships not only as a lifestyle but as a social cause.

Christopher Ryan has spent most of the last ten years combating what he calls "the standard narrative": that man's nature is to always be concerned about paternity. He started writing Sex at Dawn about eleven years ago as a PhD dissertation. At that time, Ryan was studying psychology at Saybrook University and working at a San Francisco nonprofit called Women in Community Service. "It was all women, except for me and one other guy," Ryan said, "and they were all lesbian-feminist Berkeley types."

Ryan was in the midst of reading Robert Wright's The Moral Animal, which uses evolutionary psychology to figure out whether men are congenital cheaters. Ryan had a major hard-on for the book. He'd recap Wright's theories for anyone who would listen, including the women at his nonprofit — who mostly dismissed them. "They said, 'That sounds really Victorian and phallocentric,'" Ryan recalled. He didn't take their criticisms as insult. Rather, he decided to go back and explore some of Wright's original research.

And that led him to the bonobos. Ryan contends that if you want to challenge the standard narrative of human sexuality, you can't just start at the beginning of civilization — you have to go all the way back to our primate ancestors. He explained it thus to a crowd of roughly a dozen acolytes at San Francisco's Center for Sex and Culture: "If your dog shits on your bed, and you want to know why, you're not going to study birds. You're going to look at wolves, and foxes, and coyotes." Similarly, if your girlfriend sleeps around, and you want to know why, take a look at the female bonobos at the San Diego Zoo. As Ryan's friend Carol Queen pointed out, you'll see a lot of parents at the zoo covering their children's eyes: Bonobos love to hump.

There's really no way to answer an essential question about human evolution without resorting to conjecture, so Ryan and his co-author (and wife) Jetha tried to have some humility about it. They also tried to incorporate data from as many disciplines as possible — primatology, archaeology, nutritional biology, psychology, contemporary sexuality, pornography, you name it. They drew some interesting conclusions: first and foremost, that monogamy really began with the advent of agriculture. That's when we became concerned about ownership and possession. That's when men decided that the only way to uphold a property-based society was to control women's bodies. In Ryan's estimation, it didn't take that long — evolutionarily speaking — for us to invent the phrase "Thou shalt not covet thy neighbor's wife."

But there's more. Ryan and Jetha also discovered some interesting and oft-maligned facets of female sexuality that was borne out in bonobo research. Namely, that women are raving perverts, that they're way more "bisexual" than men, and that they make a lot more noise during sex. Even more importantly: We're all perverts. Or, as Ryan would put it, we're "promiscuous" beings — promiscuous not in the sense of prurience, but in the sense of wanting to mix, being fiercely egalitarian, and wanting to have sex with as many different people as possible.

We've been taught to think in terms of competition and scarcity, Ryan says, meaning that we're told if we don't ensnare one partner within a certain time frame, our chance at reproduction will run out. He contends that this line of thinking is culturally imposed, and that in reality, we're not thinking about procreation every time we have sex — we're doing it for pleasure. "Think about the number of times you've had sex," Ryan said to the audience at Center for Sex and Culture. He paused, allowing us to mentally calculate. "Now divide that by the number of kids you have." A few people chortled, though some hid their faces uncomfortably. Point taken.

Ryan isn't particularly doctrinal — he purposefully left the pedagogical, thumb-sucking, "Where to go from here" chapter out of Sex at Dawn. But his book, which quickly landed on The New York Times bestseller list, has become a de facto Bible in the polyamory community. John and Jessica both invoke his theories when trying to define their relationship. "Monogamy automatically assumes all these rules," Jessica said. That's why, when you desire someone besides your one life partner, it's called "cheating."

John would venture even farther, arguing that open relationships are actually a more natural state than marriage and the nuclear family. "Okay, like 10 percent of people in this society say they're gay, right? I think about the same amount of people are naturally born monogamous." He continued: "But from day one, as a society, we're immediately routed towards monogamy. This shit starts right when you get out of the womb, man. Wrap that colored blanket around them, put the mother and father on the birth certificate. Boom."

He's rankled about that. "The whole 'It takes a village' thing? It shouldn't be a foreign concept." John added that Ryan's book merely validated feelings he's had for years. "It helped me find words to express how I function." John will readily admit that his parents were monogamous, and that he grew up without any kind of progressive, open relationship model to use as a reference point. Nonetheless, he's says he's been poly his whole life.

One of the people who attended Ryan's lecture was Polly Whittaker, a slender, freckled blond who is a veritable Johnny Appleseed of the local polyamory community. Whittaker is one of those rare people who can flaunt her sexual preferences without compunction, since she works in the alt-sex world full time. Born in the UK and raised in a fairly permissive family — her parents were both sex therapists, and her mother "turned a blind eye" to her father's multiple affairs — she started going to fetish clubs as a teenager, immersed herself in the "sex underground," and entered her first open relationship after immigrating to the US in 1999. "The first weekend I came was the Folsom Street Fair," she said. "It was amazing. I was like, 'Yay, this is my town, I've arrived.'"

Some people only recognize Whittaker by the costumes she wears at sex parties, which involve a lot of pink wigs and corsets. In person, though, she's polite and down-to-business, and exudes a surprisingly small amount of sexual energy. In fact, she looks like a grown-up version of the Swiss Miss hot chocolate logo: cute, fair-skinned, and much younger in appearance than her 36 years. She says that by day she's focused on writing; her partner, Scott Levkoff, is a puppeteer.

The couple launched their organization, Mission Control, in January 2001, after leasing a second-floor walk-up in the Mission. Whittaker already had her own fetish party, but she wanted to increase the clientele. "I was inviting some raver-Burner types, as well," she said, indicating that the idea of mixing those subcultures was still a little outré at that time. "Those communities really hadn't crossed yet. It was like the Goths were the fetish people and the ravers were the ecstasy people. There was no crossover."

Whittaker took it upon herself to bring the disparate tribes together, if only for the sake of throwing better parties. The result, she said, was fantastic: "colorful, costumed, sex-positive, Burning Man-oriented (but not Burning Man). We just created this space where people felt like they could explore."

The club now hosts seven different play parties, in addition to a monthly art salon. John said it runs the gamut: fairy nights, lady's nights, heavier play nights, lighter play nights, trans nights, fetish nights, sex club-oriented nights. Most events cost $30-$35 and entail a mandatory dress code. Some require all participants to bring a buddy. "You know," he said, "they want to keep the riff-raff out."

John explained that when sex parties aren't properly policed, they can attract a bad element — i.e., "dudes in sweatpants who like to jerk off while watching trannies fuck. I mean, not that it's bad to watch trannies fuck — that's hot," he said. "Sweat pants? Not so hot."

Mission Control's flagship party is called Kinky Salon, which is kind of an omnisexual catch-all. It's not polyamorous per se, but you have to be poly-friendly to go, given all the exchanging of partners that happens there. According to people who go, it looks nondescript from the outside — just a grate and a doortender. But the inside is all razzle-dazzle: wood paneling, a smokers' porch, tapestries, a dance floor with a stripper pole and mirrored disco ball, bartenders who hold your drinks (Kinky Salon has a BYOB policy and no liquor license), baskets full of condoms and lube, a back room full of beds and boxsprings and futons, people walking around in various stage of undress. Every iteration of the party has a theme (e.g., "woodland creatures," "superheroes," or "San Fransexual").

John has a fairly sunny view of Kinky Salon, at least in terms of its ability to attract a wide and representative swath of the polyamory subculture. Yes, more than half of the folks who attend are white, college-educated people in their thirties, he said. But they constitute the scene's demographic majority. "It's definitely a have-your-life-together-but-are-still-having-tons-of-fun kind of crowd," he said, adding that in general, the racial makeup pretty much mirrors that of San Francisco.

Jessica's read is a little more cynical. She's been to two Mission Control parties and says they definitely stand out in a scene that's become larger and more diffuse — in the last decade, so-called "pansexual" and "alternative adult" clubs have cropped up all over San Francisco, and many of them are a little less discriminating, in terms of the crowds they draw. All the same, she finds the crowd to be pretty specific, not so much in an elitist way as in an isolationist way. And generally, it's dominated by nerds. "You know, Burning Man people, Renn Faire people, people who are really costumed," she said. "They're older. They're not really people I'm interested in fucking."

She continued: "There's this back room where you go to have sex, and there's always this weird pile of people going at it in the middle of the room. But it's way less creepy than it could be."

Ned Mayhem, a PhD student in the sciences and second-generation polyamorist (his father also has an open marriage), would agree with that assessment. He and his partner, Maggie Mayhem, have a porn website based around their "sex geek" personae. They even invented something called a PSIgasm, which uses sensory devices to measure the strength of orgasms. (They're trying to get money to develop it, but haven't been able to work within normal fund-raising apparati — Kickstarter snubbed them.) Mayhem said that a lot of the people he meets in the so-called "sexual underground" are nerds in other parts of their lives — grad students, engineers, costume-party types, bookworms, live-action role players. They tend to be open-minded and well-educated, but always a little to the left of what mainstream society would consider "sexy."

Perhaps that explains why polyamory has formed such a flourishing, albeit circumscribed subculture. It's a scene where square pegs and misfits can reinvent themselves as Lotharios, where a self-described "socially well-adjusted" person like Jessica feels like an outlier.

Certainly, not all polyamorists attend sex parties or engage in kink — many who subscribe to the "open relationship" philosophy still consider themselves fairly vanilla. But the fact that San Francisco has such a vast and well-networked sexual underground benefits them, too, since it makes for a more tolerant environment. It also shows that the alt-sex scene, and by extension, the polyamory scene, isn't just a countercultural fluke.

At the end of the day, though, it remains marginal. And if you buy into Ryan's argument that an ownership-based society organizes itself around monogamous relationships, then polyamory may never really become mainstream. It's a fringe movement by its very definition, and some adherents would prefer that it stay that way.

In fact, there are two main obstacles facing the polyamory movement. One is that, like it or not, we're a morality-obsessed culture, and in many ways we're still a doctrinal culture. A 2009 Gallup poll showed that 92 percent of Americans think that having an extramarital affair is morally wrong. That's about twice as many as those who condemn gay and lesbian relationships, and three times as many as those who oppose the death penalty. Which is to say that as a culture, we're intractably wedded to the idea of a solid matrimonial bond. We're more amenable to the idea of legally killing someone than the idea of wrecking a marriage.

Thus, open relationships have a long way to go before becoming socially acceptable, let alone part of the status quo. Bigots who still find the idea of gay marriage unsavory probably won't cotton to nonmonogamy anytime soon.

Most of the people interviewed for this article wanted to conceal their identities, either because they feared repercussions at work — Kate, for instance, is an elementary school teacher; Ned asked that the name of his university be redacted, to avoid raising the attention of administrators — or because they hadn't "come out" to their families. Jessica said her mom mildly disapproves of open relationships and tends to dodge the subject when Jessica brings it up. A woman named Jess Young, who grew up in Texas and moved to the Bay Area after college, said her parents threw her out of the house when she was in high school for being a lesbian. "I think that polyamory would be beyond the scope of their understanding," she said.

The other problem is that humans are jealous creatures, whether or not you throw the concept of ownership into the equation. Asked if we can ever overcome jealousy, Dan Savage had a pretty straightforward answer: "No," he wrote, in an email interview. "And I say that as someone who has been in a monogamish relationship for a dozen years. Jealousy is a control, I think, a natural human emotion — just like the desire for variety and other partners."

And the truth is that polyamorous relationships are hard. Those who practice them say there's no set way of doing it. Levkoff and Whittaker are loose enough and trusting enough to let each other spend entire weekends with their respective lovers. Whittaker said she usually likes to meet the people her partner dates, particularly if it's more than just a casual romance, but she's not always interested in hearing all the details.

Jessica and John have a more hands-on approach, meaning they pretty much tell each other everything. Jessica confessed that she finds herself getting jealous in unexpected ways, and not always about sex. "I'll be like, 'Hey, you made dinner with her? No fair.'" Ned describes his relationship with Maggie as "polyfuckerous" rather than polyamorous, and says that largely owes to time constraints; he's a full-time student, she has a day job, and neither of them has the energy for endless "processing."

Some polyamorists subscribe to the idea of "compersion," which is basically a way of being happy that your partner is happy, even if that means allowing your partner to see other people. Oft-described as "the inverse of jealousy," it's defined both as an enlightened, empathic state, and a tool to surmount the feelings of possessiveness and insecurity that normally crop up in romantic relationships. Some polyamory scholars argue that compersion can be learned. Easton discusses it at length in The Ethical Slut. Jessica says she's been able to implement it sometimes. "Really," she said, "nobody's immune to jealousy."

And then, well, there's the problem of some people being liars, no matter what situation you put them in — closed, open, whatever. People in monogamous relationships cheat, but so do people in polyamorous relationships. Some people "open up" relationships in order to sabotage rather than enhance them. Savage put it bluntly: "Some people convince their partners to open their relationships, and promise them that it's not because they're not attracted to 'em anymore, but they're really done and want out of the relationship, and 'openness' for them means 'I'm out there auditioning potential new partners and as soon as I find one I'm going to dump the person I'm with."

Kate agreed. "Nonmonogamous people can cheat," she said. "It's just about being a dishonest schmuck. If you do it right, it's supposed to be thoughtful. You're supposed to do a lot of 'checking in' and talking things to death."

And, granted, people in polyamorous relationships deal with their fair share of dishonest schmucks. "The first guy I dated in New York, I think he wanted to rescue me from John," Jessica said. "He was super emotionally intimate with me, listened to me talk about my relationships, sort of alluded to the fact that he wasn't really down with the program. After two months he disappeared." She sighed. "I feel like dudes think that because you already have a boyfriend, they don't have to actually break things off."

John's been jilted, too. "There was a girl I was dating for a month or two, the sex was really hot, and she was down with the fact that I had another partner," he said. "Then I went off to New York for a few weeks, and she basically started dating someone who wanted to be monogamous." So the girl just bounced, leaving John in the lurch. "It really hurts when someone starts dating you, and then they have to stop because they're not actually poly." He explained that even though most people are theoretically born nonmonogamous, few people can actually practice nonmonogamy in a healthy, fair, fully communicative way. We're so habituated to think of romance in terms of competition and scarcity that it becomes nearly impossible to break away from that model. John said one would think that his and Jessica's pool of potential partners is a lot bigger than that of the average person, but it's actually more limited.

In the end, it's hard to say which model is better, given our social circumstances. "I think monogamy has certain pressures and discontents that complicate relationships," Savage wrote. "And I think polyamory does, too. You get to pick your poison."

It's possible to make a serious mess of a polyamorous relationship, be an unthinking, uncaring jerk, and alienate the people around you. Then again, it's also possible to create the kind of romance that John and Jessica apparently have, in which everything seems beautiful and clean.

Dr. Mitani's NYTimes Op- Ed:Fearing a Planet Without Apes

From the NYTimes.com
by JOHN C MITANI

VIEWERS of this summer’s Hollywood blockbuster “Rise of the Planet of the Apes” may be surprised to learn that before our earliest ancestors arrived on the scene roughly seven million years ago, apes really did rule the planet. As many as 40 kinds roamed Eurasia and Africa between 10 and 25 million years ago. Only five types remain. Two live in Asia, the gibbon and orangutan; another three, the chimpanzee, bonobo and gorilla, dwell in Africa. All five are endangered, several critically so. All may face extinction.

A decade ago, Congress stepped forward with a relatively cheap but vitally important effort to protect these apes through innovative conservation programs in Africa and Asia that combined taxpayer dollars with private money. But attempts to reauthorize the Great Apes Conservation Fund have gotten stuck in Congress and may become a victim of the larger debate over the national debt.

Hollywood’s depiction of apes as cunning — if not conniving — creatures comes close to reality. Fifty years ago, Jane Goodall’s observations of chimpanzees’ using tools and eating meat demonstrated just how similar apes are to humans. Subsequent fieldwork has underscored this point.

Gibbons, long thought to be monogamous, occasionally mate with individuals outside their group. Orangutans fashion tools to extract seeds that are otherwise difficult to obtain. Gorillas engage in conversational vocal exchanges. Bonobos appear to have sex not only to reproduce but also to relieve stress. Male chimpanzees form coalitions to kill their neighbors and take over their territory. If all of this seems human, there is a good reason: The apes are our closest living relatives, and in anatomy, genetics and behavior, they are much more similar to us than they are to other animals.

Apes fascinate and captivate us like no other species. They are prime attractions at zoos, and scientists from disciplines ranging from anthropology to biology and psychology study them closely in captivity and in the wild. As our first cousins in the primate family, apes help us to understand what makes us human.

I have been lucky to study all five kinds of apes during 33 years of fieldwork in Africa and Asia. When I look into the eyes of an ape, something stares back at me that seems familiar. Perhaps it is a shock of recognition, or a thoughtfulness not seen in the eyes of a frog, bird or cat. The penetrating stare makes me wonder, “What is this individual thinking?”

But as the human population expands, ape numbers continue to dwindle. In previous versions of the “Planet of the Apes” films, greed and consumption by humanlike apes threatened the world. In reality, it is these all-too-human traits that imperil apes.

Habitat destruction because of human activity, including logging, oil exploration and subsistence farming, is the biggest concern. Hunting is another major problem, especially in West and Central Africa, where a thriving “bush meat” trade severely threatens African apes. Poachers are now entering once-impenetrable forests on roads built for loggers and miners. Recently, periodic outbreaks of deadly diseases that can infect humans and apes, like Ebola, have begun to ravage populations of chimpanzees and gorillas.

The Great Apes Conservation Act, enacted in 2000, authorized the spending of $5 million annually over five years to help protect apes in the wild. The act was re-authorized in 2005 for another five years. The program matches public with private dollars to maximize the impact. Since 2006, for example, $21 million in federal dollars spent by the Great Ape Conservation Fund generated an additional $25 million in private grants and support from other governments.

The federal money may not sound like much in this era of “big science.” But those dollars have gone a long way to protect apes in countries that are desperately poor and politically volatile. The money pays for protecting habitat, battling poachers and educating local populations about the importance of these apes.

For instance, in Indonesia, where habitat loss threatens the few remaining populations of orangutans, money has been earmarked to block the conversion of forests to commercial oil palm and rubber plantations. In Congo, home to the extremely rare mountain gorilla, alternative fuels have been introduced to discourage the cutting of forests for charcoal production. In Gabon, the program has paid for law enforcement training for park rangers battling poachers. The list goes on. In all, last year, the Great Apes Conservation Fund helped to underwrite more than 50 programs in 7 Asian and 12 African countries. If Congress does not reauthorize the act, it could make it much harder to continue even the modest appropriations the great apes fund now receives.

A planet without apes is not sci-fi fantasy. If we do not take action now, sometime in the future, as Hollywood continues to produce sequels to the classic 1968 film, our children and our children’s children will ask with wonder, and perhaps a certain amount of anger, why we stood by idly while these remarkable creatures were driven to extinction.

New planet of the apes trailer

I know I seem like a bit of a propaganda machine for this movie today - but it really looks incredible! and hopefully the message on the really nasty side of keeping apes in captivity might really make people take notice of an issue I think a lot of people on this page feel really passionate about! spread the word :)

Male-Mediated Gene Flow in Patrilocal Primates

Schubert G, Stoneking C, Arandjelovic M, Boesch C, Eckhardt N, Hohmann G, Langergraber K, Lukas D, Vigilant L (2011) Male-mediated gene flow in patrilocal primates. PlosOne 6(7): e21514. doi:10.1371/journal.pone.0021514


Abstract
Background

Many group–living species display strong sex biases in dispersal tendencies. However, gene flow mediated by apparently philopatric sex may still occur and potentially alters population structure. In our closest living evolutionary relatives, dispersal of adult males seems to be precluded by high levels of territoriality between males of different groups in chimpanzees, and has only been observed once in bonobos. Still, male–mediated gene flow might occur through rare events such as extra–group matings leading to extra–group paternity (EGP) and female secondary dispersal with offspring, but the extent of this gene flow has not yet been assessed.

Methodology/Principal Findings
Using autosomal microsatellite genotyping of samples from multiple groups of wild western chimpanzees (Pan troglodytes verus) and bonobos (Pan paniscus), we found low genetic differentiation among groups for both males and females. Characterization of Y–chromosome microsatellites revealed levels of genetic differentiation between groups in bonobos almost as high as those reported previously in eastern chimpanzees, but lower levels of differentiation in western chimpanzees. By using simulations to evaluate the patterns of Y–chromosomal variation expected under realistic assumptions of group size, mutation rate and reproductive skew, we demonstrate that the observed presence of multiple and highly divergent Y–haplotypes within western chimpanzee and bonobo groups is best explained by successful male–mediated gene flow.

Conclusions/Significance

The similarity of inferred rates of male–mediated gene flow and published rates of EGP in western chimpanzees suggests this is the most likely mechanism of male–mediated gene flow in this subspecies. In bonobos more data are needed to refine the estimated rate of gene flow. Our findings suggest that dispersal patterns in these closely related species, and particularly for the chimpanzee subspecies, are more variable than previously appreciated. This is consistent with growing recognition of extensive behavioral variation in chimpanzees and bonobos.

Promiscuous apes make more sperm

(Camilo the bonobo by Carol Deimel - bonobos are not actually described in this study)

Promiscuous apes make more sperm
By ELLA DAVIES

Chimpanzees produce 200 times more sperm than gorillas, the world's largest primates, and 14 times more than orangutans, scientists based in Japan reveal.

Promiscuous ape species have bigger testicles, and the latest discovery finally provides evidence that they also produce more sperm. Scientists previously proposed that chimps have large testicles because several males mate with a single female, and so have to produce more sperm in order to compete. For their research, published in the American Journal of Primatology, scientists studied chimpanzees, orangutans and gorillas from zoos in Japan and Indonesia. Analysing samples of testicular tissues at a microscopic level, researchers found remarkable variation between the apes. They found that the sperm-producing tissue lining gorillas' testes was much thinner than that of orangutans and chimpanzees. Chimpanzees were found to produce 14 times more sperm than orangutans and even more than the world's largest primates.

"Our data indicated that a chimpanzee usually produces about two hundred times more sperm than a gorilla," explained researcher Hideko Fujii-Hanamoto. For these three species of ape, the scientists have now proven that testes size is proportionate to sperm production. The researchers claim that these findings also support theories that sperm production relates directly to reproductive competition and mating behaviour.

Previous studies proposed that testes are smaller in polygynous species such as gorillas where one alpha male monopolises mating with multiple females. In promiscuous species such as chimps however, there is greater competition between males as several copulate with one female.

This competition is thought to be the driving factor for sperm production and larger testes are thought to produce more sperm. However, practical limitations meant sperm production in apes was difficult to accurately measure. "It is generally difficult to get semen from the animals even if they [are] kept in zoological gardens," said Ms Fujii-Hanamoto. "Therefore, the testis weight or the ratio of testis weight [to] body weight was used to estimate the ability of sperm production."

Visual observations confirmed that chimpanzees have larger testes compared to their body size than gorillas but it was not clear whether they actually produced more sperm.

The Bi-Polar Ape: Torn between love and war

In this short film sponsored by the Leakey Foundation, psychologist Steven Pinker and primatologists Frans de Waal and Richard Wrangham grapple with human nature. Are we essentially peace-loving, like bonobos, or doomed to continual violent conflict, like chimpanzees?

For the last 20,000 years human brains have ben getting smaller


From NPR
Our Brains Are Shrinking. Are We Getting Dumber?

When it comes to brain size, bigger doesn't always mean better. As humans continue to evolve, scientists say our brains are actually getting smaller.

The downsizing of human brains is an evolutionary fact that took science writer Kathleen McAuliffe by surprise.

"I said, 'What? I thought it was getting bigger!'" she tells NPR's Jacki Lyden. That was the story up to 20,000 years ago, she learned. Then, the brains of our ancestors reversed course and started getting smaller — and they've been shrinking ever since.

Cro-Magnon man, who lived in Europe 20,000 to 30,000 years ago, had the biggest brains of any human species. In comparison, today's human brain is about 10 percent smaller. It's a chunk of brain matter "roughly equivalent to a tennis ball in size," McAuliffe says.

The experts aren't sure about the implications of this evolutionary trend. Some think it might be a dumbing-down process. One cognitive scientist, David Geary, argues that as human society grows increasingly complex, individuals don't need to be as intelligent in order to survive and reproduce.

But not all researchers are so pessimistic. Brian Hare, an anthropologist at the Duke University Institute for Brain Sciences, thinks the decrease in brain size is actually an evolutionary advantage.

The Domesticated Brain

"A smaller brain is the signature of selection against aggression," Hare tells Lyden. "Another way to say that is an increase in tolerance."

Hare says when a population selects against aggression, they can be considered to be domesticated. And for a variety of domesticated animals like apes, dogs or turkeys, you can see certain physical characteristics emerge. Among these traits are a lighter and more slender skeleton, a flattened forehead — and decreased brain size.

Hare's studies focus on chimpanzees and bonobos. In evolutionary terms, they are much like humans, but are physically quite different from one another. Bonobos have smaller brains than chimpanzees — and are also much less aggressive.

While both have the cognitive ability to solve a given puzzle, Hare says, chimpanzees are much less likely to accomplish it if it involves teamwork. Not so with bonobos.

"If the food is quite sparse and it's not easy to share, [bonobos] can solve the problem," Hare says. "Chimpanzees, in that same context — where there's not much food and it's not easy to share — they just refuse to work together. They can't solve the problem, even though they know how."

Hare does admit that the shrinking human brain could signal an evolutionary dumbing-down, but more important is what the phenomenon tells us about ourselves. Comparing our evolution to that of other animals enriches our understanding of the human condition.

"The nice thing about studying animals and human nature," Hare says, "is that it helps us design or think of some strategies that deal with our darker sides."

Among African Apes
Stories and Photos from the Field
Edited by Martha M. Robbins, and Christophe Boesch

Description:
These compelling stories and photographs take us to places like Bwindi Impenetrable National Park in Uganda, Ivindo National Park in Gabon, and the Taï National Park in Côte d’Ivoire for an intimate and revealing look at the lives of African wild apes—and at the lives of the humans who study them. In tales of adventure, research, and conservation, veteran field researchers and conservationists describe exciting discoveries made over the past few decades about chimpanzees, bonobos, and gorillas. The book features vivid descriptions of interactions among these highly intelligent creatures as they hunt, socialize, and play. More difficult themes emerge as well, including the threats apes face from poaching, disease, and deforestation. In stories that are often moving and highly personal, this book takes measure of how special the great apes are and discusses positive conservation efforts, including ecotourism, that can help bring these magnificent animals back from the brink of extinction.

Bonobos!

So much happened yesterday and I was all tied up so lots of posts today - visit the facebook page or the blog to make sure you didn't miss anything. First up, a double post on bonobos, a quick book review and a new movie. Have a great weekend everyone- MA


I FINALLY found time to read Vanessa Wood's book "bonobo handshake" a few weeks ago. I posted about the book and Vanessa and Brian Hare's work with bonobos HERE and HERE and knowing Vanessa and her hysterical yet informative writing style I knew I would love it. I am so happy to say that the book is AMAZING! Anyone who has worked in a developing and war-torn country I am sure will really enjoy it. Its not only about bonobos, research and conservation as you might expect. Vanessa writes about the doubts and fears a "city girl" experiences working under these conditions. Its about love and relationships and there is also the perfect amount of information on the history of conflict in DRC and its neighbouring countries. The book is beyond charming and I cannot recommend it enough. I am sure anyone who reads this blog would really enjoy it. - MA

Hausergate gives ammo to pro-religion anti-science proponents

An interesting article by Dr. de Waal...must say I disagree with several points, especially that we need religion because it offers moral guidance and science cannot replace that. I think many of the "moral dilemas" out there are a total consequence of the weird rules of religion. Would we even care about homosexuality if it were not for religious dogma? We don't need science to provide moral answers as a replacement for religion, we would be better offer if we just could act as a society with its own evolutionarily built in consequences. Why should determining whether a course of action is "morally" right or wrong be any different then picking what to eat for lunch...somethings don't have right and wrong answers, but you can be sure that if you go around raping people, society will disaprove and treat you accordingly.
Also I think the part about altruism is weak but I like the discussion on empathy.
Most importantly though, I did not realize how much ammo "Hausergate" has given the anti-science pro-religion faction, and that really is too bad. -MA

Morals Without God?
By FRANS DE WAAL

I was born in Den Bosch, the city after which Hieronymus Bosch named himself. [1] This obviously does not make me an expert on the Dutch painter, but having grown up with his statue on the market square, I have always been fond of his imagery, his symbolism, and how it relates to humanity’s place in the universe. This remains relevant today since Bosch depicts a society under a waning influence of God.

His famous triptych with naked figures frolicking around — “The Garden of Earthly Delights” — seems a tribute to paradisiacal innocence. The tableau is far too happy and relaxed to fit the interpretation of depravity and sin advanced by puritan experts. It represents humanity free from guilt and shame either before the Fall or without any Fall at all. For a primatologist, like myself, the nudity, references to sex and fertility, the plentiful birds and fruits and the moving about in groups are thoroughly familiar and hardly require a religious or moral interpretation. Bosch seems to have depicted humanity in its natural state, while reserving his moralistic outlook for the right-hand panel of the triptych in which he punishes — not the frolickers from the middle panel — but monks, nuns, gluttons, gamblers, warriors, and drunkards.

Five centuries later, we remain embroiled in debates about the role of religion in society. As in Bosch’s days, the central theme is morality. Can we envision a world without God? Would this world be good? Don’t think for one moment that the current battle lines between biology and fundamentalist Christianity turn around evidence. One has to be pretty immune to data to doubt evolution, which is why books and documentaries aimed at convincing the skeptics are a waste of effort. They are helpful for those prepared to listen, but fail to reach their target audience. The debate is less about the truth than about how to handle it. For those who believe that morality comes straight from God the creator, acceptance of evolution would open a moral abyss.

Our Vaunted Frontal Lobe

Echoing this view, Reverend Al Sharpton opined in a recent videotaped debate: “If there is no order to the universe, and therefore some being, some force that ordered it, then who determines what is right or wrong? There is nothing immoral if there’s nothing in charge.” Similarly, I have heard people echo Dostoevsky’s Ivan Karamazov, exclaiming that “If there is no God, I am free to rape my neighbor!”

Perhaps it is just me, but I am wary of anyone whose belief system is the only thing standing between them and repulsive behavior. Why not assume that our humanity, including the self-control needed for livable societies, is built into us? Does anyone truly believe that our ancestors lacked social norms before they had religion? Did they never assist others in need, or complain about an unfair deal? Humans must have worried about the functioning of their communities well before the current religions arose, which is only a few thousand years ago. Not that religion is irrelevant — I will get to this — but it is an add-on rather than the wellspring of morality.

Deep down, creationists realize they will never win factual arguments with science. This is why they have construed their own science-like universe, known as Intelligent Design, and eagerly jump on every tidbit of information that seems to go their way. The most recent opportunity arose with the Hauser affair. A Harvard colleague, Marc Hauser, has been accused of eight counts of scientific misconduct, including making up his own data. Since Hauser studied primate behavior and wrote about morality, Christian Web sites were eager to claim that “all that people like Hauser are left with are unsubstantiated propositions that are contradicted by millennia of human experience” (Chuck Colson, Sept. 8, 2010). A major newspaper asked “Would it be such a bad thing if Hausergate resulted in some intellectual humility among the new scientists of morality?” (Eric Felten, Aug. 27, 2010). Even a linguist could not resist this occasion to reaffirm the gap between human and animal by warning against “naive evolutionary presuppositions.”

These are rearguard battles, however. Whether creationists jump on this scientific scandal or linguists and psychologists keep selling human exceptionalism does not really matter. Fraud has occurred in many fields of science, from epidemiology to physics, all of which are still around. In the field of cognition, the march towards continuity between human and animal has been inexorable — one misconduct case won’t make a difference. True, humanity never runs out of claims of what sets it apart, but it is a rare uniqueness claim that holds up for over a decade. This is why we don’t hear anymore that only humans make tools, imitate, think ahead, have culture, are self-aware, or adopt another’s point of view.

If we consider our species without letting ourselves be blinded by the technical advances of the last few millennia, we see a creature of flesh and blood with a brain that, albeit three times larger than a chimpanzee’s, doesn’t contain any new parts. Even our vaunted prefrontal cortex turns out to be of typical size: recent neuron-counting techniques classify the human brain as a linearly scaled-up monkey brain.[2] No one doubts the superiority of our intellect, but we have no basic wants or needs that are not also present in our close relatives. I interact on a daily basis with monkeys and apes, which just like us strive for power, enjoy sex, want security and affection, kill over territory, and value trust and cooperation. Yes, we use cell phones and fly airplanes, but our psychological make-up remains that of a social primate. Even the posturing and deal-making among the alpha males in Washington is nothing out of the ordinary.

The Pleasure of Giving

Charles Darwin was interested in how morality fits the human-animal continuum, proposing in “The Descent of Man”: “Any animal whatever, endowed with well-marked social instincts … would inevitably acquire a moral sense or conscience, as soon as its intellectual powers had become as well developed … as in man.”

Unfortunately, modern popularizers have strayed from these insights. Like Robert Wright in “The Moral Animal,” they argue that true moral tendencies cannot exist — not in humans and even less in other animals — since nature is one hundred percent selfish. Morality is just a thin veneer over a cauldron of nasty tendencies. Dubbing this position “Veneer Theory” (similar to Peter Railton’s “moral camouflage”), I have fought it ever since my 1996 book “Good Natured.” Instead of blaming atrocious behavior on our biology (“we’re acting like animals!”), while claiming our noble traits for ourselves, why not view the entire package as a product of evolution? Fortunately, there has been a resurgence of the Darwinian view that morality grew out of the social instincts. Psychologists stress the intuitive way we arrive at moral judgments while activating emotional brain areas, and economists and anthropologists have shown humanity to be far more cooperative, altruistic, and fair than predicted by self-interest models. Similarly, the latest experiments in primatology reveal that our close relatives will do each other favors even if there’s nothing in it for themselves.

Chimpanzees and bonobos will voluntarily open a door to offer a companion access to food, even if they lose part of it in the process. And capuchin monkeys are prepared to seek rewards for others, such as when we place two of them side by side, while one of them barters with us with differently colored tokens. One token is “selfish,” and the other “prosocial.” If the bartering monkey selects the selfish token, it receives a small piece of apple for returning it, but its partner gets nothing. The prosocial token, on the other hand, rewards both monkeys. Most monkeys develop an overwhelming preference for the prosocial token, which preference is not due to fear of repercussions, because dominant monkeys (who have least to fear) are the most generous.

Even though altruistic behavior evolved for the advantages it confers, this does not make it selfishly motivated. Future benefits rarely figure in the minds of animals. For example, animals engage in sex without knowing its reproductive consequences, and even humans had to develop the morning-after pill. This is because sexual motivation is unconcerned with the reason why sex exists. The same is true for the altruistic impulse, which is unconcerned with evolutionary consequences. It is this disconnect between evolution and motivation that befuddled the Veneer Theorists, and made them reduce everything to selfishness. The most quoted line of their bleak literature says it all: “Scratch an ‘altruist,’ and watch a ‘hypocrite’ bleed.”[3]

It is not only humans who are capable of genuine altruism; other animals are, too. I see it every day. An old female, Peony, spends her days outdoors with other chimpanzees at the Yerkes Primate Center’s Field Station. On bad days, when her arthritis is flaring up, she has trouble walking and climbing, but other females help her out. For example, Peony is huffing and puffing to get up into the climbing frame in which several apes have gathered for a grooming session. An unrelated younger female moves behind her, placing both hands on her ample behind and pushes her up with quite a bit of effort, until Peony has joined the rest.

We have also seen Peony getting up and slowly move towards the water spigot, which is at quite a distance. Younger females sometimes run ahead of her, take in some water, then return to Peony and give it to her. At first, we had no idea what was going on, since all we saw was one female placing her mouth close to Peony’s, but after a while the pattern became clear: Peony would open her mouth wide, and the younger female would spit a jet of water into it.

Such observations fit the emerging field of animal empathy, which deals not only with primates, but also with canines, elephants, even rodents. A typical example is how chimpanzees console distressed parties, hugging and kissing them, which behavior is so predictable that scientists have analyzed thousands of cases. Mammals are sensitive to each other’s emotions, and react to others in need. The whole reason people fill their homes with furry carnivores and not with, say, iguanas and turtles, is because mammals offer something no reptile ever will. They give affection, they want affection, and respond to our emotions the way we do to theirs.

Mammals may derive pleasure from helping others in the same way that humans feel good doing good. Nature often equips life’s essentials — sex, eating, nursing — with built-in gratification. One study found that pleasure centers in the human brain light up when we give to charity. This is of course no reason to call such behavior “selfish” as it would make the word totally meaningless. A selfish individual has no trouble walking away from another in need. Someone is drowning: let him drown. Someone cries: let her cry. These are truly selfish reactions, which are quite different from empathic ones. Yes, we experience a “warm glow,” and perhaps some other animals do as well, but since this glow reaches us via the other, and only via the other, the helping is genuinely other-oriented.

Bottom-Up Morality

A few years ago Sarah Brosnan and I demonstrated that primates will happily perform a task for cucumber slices until they see others getting grapes, which taste so much better. The cucumber-eaters become agitated, throw down their measly veggies and go on strike. A perfectly fine food has become unpalatable as a result of seeing a companion with something better.

We called it inequity aversion, a topic since investigated in other animals, including dogs. A dog will repeatedly perform a trick without rewards, but refuse as soon as another dog gets pieces of sausage for the same trick. Recently, Sarah reported an unexpected twist to the inequity issue, however. While testing pairs of chimps, she found that also the one who gets the better deal occasionally refuses. It is as if they are satisfied only if both get the same. We seem to be getting close to a sense of fairness.

Such findings have implications for human morality. According to most philosophers, we reason ourselves towards a moral position. Even if we do not invoke God, it is still a top-down process of us formulating the principles and then imposing those on human conduct. But would it be realistic to ask people to be considerate of others if we had not already a natural inclination to be so? Would it make sense to appeal to fairness and justice in the absence of powerful reactions to their absence? Imagine the cognitive burden if every decision we took needed to be vetted against handed-down principles. Instead, I am a firm believer in the Humean position that reason is the slave of the passions. We started out with moral sentiments and intuitions, which is also where we find the greatest continuity with other primates. Rather than having developed morality from scratch, we received a huge helping hand from our background as social animals.

At the same time, however, I am reluctant to call a chimpanzee a “moral being.” This is because sentiments do not suffice. We strive for a logically coherent system, and have debates about how the death penalty fits arguments for the sanctity of life, or whether an unchosen sexual orientation can be wrong. These debates are uniquely human. We have no evidence that other animals judge the appropriateness of actions that do not affect themselves. The great pioneer of morality research, the Finn Edward Westermarck, explained what makes the moral emotions special: “Moral emotions are disconnected from one’s immediate situation: they deal with good and bad at a more abstract, disinterested level.” This is what sets human morality apart: a move towards universal standards combined with an elaborate system of justification, monitoring and punishment.

At this point, religion comes in. Think of the narrative support for compassion, such as the Parable of the Good Samaritan, or the challenge to fairness, such as the Parable of the Workers in the Vineyard, with its famous conclusion “The last will be first, and the first will be last.” Add to this an almost Skinnerian fondness of reward and punishment — from the virgins to be met in heaven to the hell fire that awaits sinners — and the exploitation of our desire to be “praiseworthy,” as Adam Smith called it. Humans are so sensitive to public opinion that we only need to see a picture of two eyes glued to the wall to respond with good behavior, which explains the image in some religions of an all-seeing eye to symbolize an omniscient God.

The Atheist Dilemma

Over the past few years, we have gotten used to a strident atheism arguing that God is not great (Christopher Hitchens) or a delusion (Richard Dawkins). The new atheists call themselves “brights,” thus hinting that believers are not so bright. They urge trust in science, and want to root ethics in a naturalistic worldview.

While I do consider religious institutions and their representatives — popes, bishops, mega-preachers, ayatollahs, and rabbis — fair game for criticism, what good could come from insulting individuals who find value in religion? And more pertinently, what alternative does science have to offer? Science is not in the business of spelling out the meaning of life and even less in telling us how to live our lives. We, scientists, are good at finding out why things are the way they are, or how things work, and I do believe that biology can help us understand what kind of animals we are and why our morality looks the way it does. But to go from there to offering moral guidance seems a stretch.

Even the staunchest atheist growing up in Western society cannot avoid having absorbed the basic tenets of Christian morality. Our societies are steeped in it: everything we have accomplished over the centuries, even science, developed either hand in hand with or in opposition to religion, but never separately. It is impossible to know what morality would look like without religion. It would require a visit to a human culture that is not now and never was religious. That such cultures do not exist should give us pause.

Bosch struggled with the same issue — not with being an atheist, which was not an option — but science’s place in society. The little figures in his paintings with inverted funnels on their heads or the buildings in the form of flasks, distillation bottles, and furnaces reference chemical equipment.[4] Alchemy was gaining ground yet mixed with the occult and full of charlatans and quacks, which Bosch depicted with great humor in front of gullible audiences. Alchemy turned into science when it liberated itself from these influences and developed self-correcting procedures to deal with flawed or fabricated data. But science’s contribution to a moral society, if any, remains a question mark.

Other primates have of course none of these problems, but even they strive for a certain kind of society. For example, female chimpanzees have been seen to drag reluctant males towards each other to make up after a fight, removing weapons from their hands, and high-ranking males regularly act as impartial arbiters to settle disputes in the community. I take these hints of community concern as yet another sign that the building blocks of morality are older than humanity, and that we do not need God to explain how we got where we are today. On the other hand, what would happen if we were able to excise religion from society? I doubt that science and the naturalistic worldview could fill the void and become an inspiration for the good. Any framework we develop to advocate a certain moral outlook is bound to produce its own list of principles, its own prophets, and attract its own devoted followers, so that it will soon look like any old religion.

Social Activism: Chimps in entertainment, cover of new Daily Show book FAILs


Jon Stewart (who i adore) & the Daily Show (which i adore) have a new book out and on the cover is a chimpanzee. I think everyone on here knows why this is unacceptable. A lot of great conservationists, scientists and animal rights activists have already posted on the wall of their facebook page. Please consider adding your voice, or "liking" the comments of others to show your support (You must first "like" the page to post) Thanks, MA.

Here is my post:
"I see that a lot of people here think this "chimpanzee issue" is one of animal activist nut jobs. It is not. It is a major conservation problem.

Bonobo conservation via community development

Into the Congo: saving bonobos means aiding left-behind communities, an interview with Gay Reinartz
BY JEREMY HANCE

Unlike every other of the world's great apes—the gorilla, chimpanzee, and orangutan—saving the bonobo means focusing conservation efforts on a single nation, the Democratic Republic of the Congo. While such a fact would seem to simplify conservation, according to the director of the The Bonobo and Congolese Biodiversity Initiative (BCBI), Gay Reinartz, it in fact complicates it: after decades of one of world's brutal civil wars, the DRC remains among the world's most left-behind nations. Widespread poverty, violence, politically instability, corruption, and lack of basic infrastructure have left the Congolese people in desperate straits.

"From a place of privilege, I have had the opportunity to look upon a society essentially reduced to its simplest, most fundamental term—survival. In Congo, I have witnessed wider extremes of cruelty and kindness, exploitation and generosity, revenge and forgiveness," Gay Reinartz told mongabay.com in an interview. While developing and directing BCBI—a program established through the Zoological Society of Milwaukee (ZSM)—Reinartz has spent years working closely with Congolese communities in order to improve lives and, hopefully, ensure the long-term survival of the bonobo.

From the moment Reinartz first met a troop of bonobos as they arrived at the Milwaukee Zoo, she was smitten. "They were charming," she says of that encounter. Bonobos are most closely related to chimpanzees, but have been considered a separate species since the 1930s. While bonobos have some notable physical differences from chimpanzees, it is their behavioral differences that have really grasped the public imagination, especially their reputation of being lovers, not fighters.

"Bonobos have a playful nature. The idea that bonobos are a peace loving society is true—but to a certain extent," Reinartz explains. "This trait is relative and must be seen in comparison to other great ape species. The media have overplayed bonobos as peaceniks. While it’s true that bonobos show less aggression, that they have less big-male domination, that 'wars' have not been observed, they do fight. […] Nevertheless, the bonobo has evolved ways to deal with social tension and reduce aggression or conflict—that being social sexual interactions—having intimacy and intercourse for reasons other than reproduction—and empathy."

To save the world's least known great ape, the BCBI has developed a number of initiatives. The organization has trained Congolese field workers to survey bonobo and other large mammal populations in Salongo National Park, providing baseline data for before and after conflict erupted in the region. The surveys are also studying different bonobo densities in a number of sites in the park, variously affected by poaching.

BCBI has also established programs to support protective measures in the park, including setting up an anti-poaching patrol, training park guards, and coming through with supplies and funds for park guards in emergencies. Reinartz says the situation is incredibly difficult for park guards, and often dangerous especially when facing elephant poachers.

"There are fewer than two hundred park guards who are responsible for patrolling this entire area. They lack training, guns, means of transportation, communication, and basic forest equipment. There is approximately one gun per four men. They are no match for the well-armed elephant poachers who come in brandishing AK-47s."

The biggest current threat to bonobos and most of the wildlife in the park is hunting: the great apes are killed for bushmeat as well as trapped in snares meant for other big mammals. Given the poverty of the region, and few ways to make money, the bushmeat trade has boomed in the Democratic Republic of Congo.

"So, how do we convince them not to hunt? We have to give communities incentives to do something else and begin to build greater awareness. At the same time then, the park guards have to do their job in law enforcement. The two approaches must work from either side simultaneously—one with the other," says Reinartz.

Giving communities incentives not to hunt includes working on providing new economic and education opportunities, both of which are basically non-existent in the region. BCBI has established a farming cooperative with a local NGO, helping villagers can learn to grow their own food and hopefully start up markets to sell the extra. The organization has also set-up primary schools, including providing materials and paying local teachers, and adult literacy courses. In such a region, if conservation is to succeed, conservation programs have to become humanitarian programs, filling in the role of a crippled government, a battered economy, and a region still suffering from bouts of violence. Part of the battle, says Reinartz, is convincing people that conservationists can be trusted, that BCBI won't abandon communities if times get rough again.

"For many people, even though they might understand why and regret that elephants, bonobos and other animals have vanished from their communal forests, they consider conservation efforts as just another way they are being cheated and neglected. To change these attitudes will take a long time and program consistency to overcome generations of negative conditioning and hopelessness," she says, adding that "what surprises me is that they aren’t more cynical than they are."

Even in the face of war and poverty, Reinartz is clearly amazed at the generosity and strength of many of the Congolese people.

In a September 2010 interview Gay Reinartz spoke about the uniqueness of the bonobo, the challenge of saving a species in one of the world's most forgotten places: the Congo, and of combining conservation work with humanitarian programs.

Reinartz will be presenting at the up-coming Wildlife Conservation Network Expo in San Francisco on October 3rd, 2010.

Spain FTW!: Legislation about to pass that will ensure basic rights to all great apes


This is really fantastic news! The second article from the Sunday Times raises some interesting points on the controversy surrounding this move by Spain. Despite the issues raised, I really do believe this is a major step in the right direction for apes globally (both in captivity and in the wild). It will ensure that apes in zoos are really treated with the highest standards. They are ambassadors for their wild counterparts and they should be treated as such, they should be expensive financially and politically to house so that we do not forget the sacrifice they are making with their captivity. With this legislation there will be no more apes used in advertising, circuses or research throughout Spain. It should also give other countries that do house huge numbers of captive apes (I'm looking at you U.S.A.) the impetus and the model for bringing such legislation to the table.

Spanish parliament to extend rights to apes
by MARTIN ROBERTS

Spain's parliament voiced its support on Wednesday for the rights of great apes to life and freedom in what will apparently be the first time any national legislature has called for such rights for non-humans. [Note: I am not sure how accurate this statement is, Currently there is a research ban on great apes in the Netherlands, New Zealand, the United Kingdom, Sweden, Germany and Austria. "These countries have ruled that chimpanzees, bonobos, gorillas, and orangutans are cognitively so similar to humans that using them as test subjects is unethical. Austria is the only country in the world where experiments on lesser apes, the gibbons, are completely banned too." (excerpt from Wikipedia) -MA]

Parliament's environmental committee approved resolutions urging Spain to comply with the Great Apes Project, devised by scientists and philosophers who say our closest genetic relatives deserve rights hitherto limited to humans.

"This is a historic day in the struggle for animal rights and in defense of our evolutionary comrades, which will doubtless go down in the history of humanity," said Pedro Pozas, Spanish director of the Great Apes Project.

Spain may be better known abroad for bull-fighting than animal rights but the new measures are the latest move turning once-conservative Spain into a liberal trailblazer.

Spain did not legalize divorce until the 1980s, but Prime Minister Jose Luis Rodriguez Zapatero's Socialist government has legalized gay marriage, reduced the influence of the Catholic Church in education and set up an Equality Ministry.

The new resolutions have cross-party or majority support and are expected to become law and the government is now committed to update the statute book within a year to outlaw harmful experiments on apes in Spain.

"We have no knowledge of great apes being used in experiments in Spain, but there is currently no law preventing that from happening," Pozas said.

Keeping apes for circuses, television commercials or filming will also be forbidden and breaking the new laws will become an offence under Spain's penal code.

Keeping an estimated 315 apes in Spanish zoos will not be illegal, but supporters of the bill say conditions will need to improve drastically in 70 percent of establishments to comply with the new law.

Philosophers Peter Singer and Paola Cavalieri founded the Great Ape Project in 1993, arguing that "non-human hominids" like chimpanzees, gorillas, orang-utans and bonobos should enjoy the right to life, freedom and not to be tortured.

Apes get legal rights in Spain, to surprise of bullfight critics

Spain is to become the first country to extend legal rights to apes, wrongfooting animal rights activists who have long campaigned against bullfighting in the country.

In what is thought to be the first time a national legislature has granted such rights to animals, the Spanish parliament’s environmental committee voted to approve resolutions committing the country to the Great Apes Project, designed by scientists and philosophers who say that humans’ closest biological relatives also deserve rights.

The resolution, adopted with crossparty support, calls on the Government to promote the Great Apes Project internationally and ensure the protection of apes from “abuse, torture and death”. “This is a historic moment in the struggle for animal rights,” Pedro Pozas, the Spanish director of the Great Apes Project, told The Times. “It will doubtless be remembered as a key moment in the defence of our evolutionary comrades.”

Reactions to the vote were mixed. Many Spaniards were perplexed that the country should consider it a priority when the economy is slowing sharply and Spain has been rocked by violent fuel protests. Others thought it was a strange decision, given that Spain has no wild apes of its own.

In an editorial yesterday, the Madrid daily El Mundo noted that the only apes in Spain were “the ones that could cross over from Gibraltar”, and questioned why the country should become “the principal flag-bearer of the apes” cause. “With the problems that Spanish farmers and fishermen are experiencing, it is surprising that members of Congress should dedicate their efforts to trying to turn the country of bullfighting into the principal defender of the apes,” it wrote.

Spain’s conservative Popular Party also complained that the resolution sought to give animals the same rights as humans — something that the Socialist Government denies. Some critics questioned why Spain should afford legal protection from death or torture to great apes but not bulls. But Mr Pozas said that the vote would set a precedent, establishing legal rights for animals that could be extended to other species. “We are seeking to break the species barrier — we are just the point of the spear,” he said.

The resolutions will outlaw harmful experiments on great apes, though activist say that they have no knowledge of any being carried out in Spain. It will also make keeping great apes for circuses, TV commercials or filming a criminal offence.

Keeping apes in zoos will remain legal, but conditions for the 350 apes in Spanish zoos will have to improve. Animal rights activists say that 70 per cent of apes in Spanish zoos live in sub-human conditions. The philosophers Peter Singer and Paola Cavalieri founded the Great Ape Project in 1993, saying that hominids such as chimpanzees, gorillas and orang-utans should enjoy the right to life and freedom and not to be mistreated.

Mothers matter! Maternal support, dominance status and mating success in male bonobos

Official Press Release:
Mothers matter

Success makes sexy – this does not only apply to human beings, but also to various animals. Male bonobos appear to benefit from this phenomenon as well. A team of researchers led by Gottfried Hohmann of the Max Planck Institute for Evolutionary Anthropology has discovered that the higher up a male bonobo is placed in the social hierarchy, the greater his mating success is with female bonobos. But even males who are not so highly placed are still in with a chance of impressing females. Researchers reported for the first time direct support from mothers to their sons in agonistic conflicts over access to estrous females. Martin Surbeck from the Max Planck Institute for Evolutionary Anthropology discovered that the presence of mothers enhances the mating success of their sons and thereby causes mating to be more evenly distributed among the males. As bonobo males remain in their natal group and adult females have the leverage to intervene in male conflicts, maternal support extends into adulthood and potentially affects male reproductive success. (Proceedings of the Royal Society B: Biological Sciences. 01.09.2010)

Variation in male mating success is often related to rank differences. Males who are unable to monopolize estrous females alone may engage in coalitions with other group members to chase higher ranking males off these females and to thus enhance their own mating success.

Studies on chimpanzees and dolphins suggest that coalitions are independent of kinship. Information from species in which females remain in their natal group, on the other hand, shows the importance of kin support, especially from mothers, on the reproductive success of their daughters. Therefore, one might expect a similar effect on sons in species in which males remain in their natal group like bonobos. "With our study we wanted to find out whether in bonobos the mating success of the sons was indeed influenced by the support they received from their mothers", says Martin Surbeck.

The researchers evaluated the determinants of mating success in male bonobos using data from nine males in a wild population and determined kinship relations using genetic markers. Results reveal a steep, linear male dominance hierarchy and a positive correlation between dominance status and mating success. In addition to rank, the presence of mothers does indeed enhance the mating success of sons and thereby reduces the proportion of matings by the highest ranking male.

Mothers and sons seem to be inseparable and mothers provide agonistic aid to sons in conflicts with other males. As bonobos are male-philopatric, i.e. males remain in their natal group, and adult females occupy high dominance status, maternal support extends into adulthood and females have the leverage to intervene in male conflicts. The absence of female support to unrelated males suggests that mothers gain indirect fitness benefits by supporting their sons. "Females do not grant this kind of support to unrelated males. By helping their sons the mothers may likely increase the number of their own grandchildren", says Martin Surbeck.

Abstract
Variation in male mating success is often related to rank differences. Males who are unable to monopolize oestrous females alone may engage in coalitions, thus enhancing their mating success. While studies on chimpanzees and dolphins suggest that coalitions are independent of kinship, information from female philopatric species shows the importance of kin support, especially from mothers, on the reproductive success of females. Therefore, one might expect a similar effect on sons in male philopatric species. We evaluate mating success determinants in male bonobos using data from nine male individuals from a wild population. Results reveal a steep, linear male dominance hierarchy and a positive correlation between dominance status and mating success. In addition to rank, the presence of mothers enhances the mating success of sons and reduces the proportion of matings by the highest ranking male. Mothers and sons have high association rates and mothers provide agonistic aid to sons in conflicts with other males. As bonobos are male-philopatric and adult females occupy high dominance status, maternal support extends into adulthood and females have the leverage to intervene in male conflicts. The absence of female support to unrelated males suggests that mothers gain indirect fitness benefits by supporting their sons.
