Moscow's stray dogs well adapted to Russian metropolitain life



In Moscow's Metro, a Stray Dog's Life Is Pretty Cushy, and Zoologists Notice
By MARK SCHOOFS
From The Wall street Journal online

MOSCOW -- Like human commuters, this city's stray dogs can often be spotted traveling on the subway, waiting patiently for a train to pull in and its doors to slide open.

In Soviet times, dogs were barred from Moscow's metro. Today, however, they are so common there -- curling up on empty seats, nuzzling their neighbors, lounging in stations -- that there is even a Web site devoted to them: www.metrodog.ru.

A tiny group of zoologists study Moscow's stray dogs and how they're adapting to a rapidly changing city. Among them is Alexei Vereshchagin. He set out to study wolves -- "such a romantic creature," he says -- but as science funding crumbled with the Soviet government, he couldn't.

WSJ's Mark Schoofs on why stray dogs are everywhere in Moscow, having adapted to the construction boom and learning to share space with humans. Also, zoologist Alexei Vereshchagin on these dogs' behaviors.

So the 31-year-old, rust-bearded Mr. Vereshchagin started studying strays instead, and loved it. "The behavior of stray dogs is like theater," he says.

As the number of cars in Moscow has exploded, and their speed increased from the days of Soviet clunkers, strays have learned to cross the street with pedestrians. They can also be seen occasionally waiting for a green light. (Dogs are colorblind, so researchers theorize they recognize the shape or position of the walking-man signal.)

Back in the lean Soviet era, restaurants and the now-ubiquitous fast-food kiosks were scarce, so dogs were less likely to beg and more likely to forage through garbage, the zoologists say. Foraging dogs prospered best in the vast industrial zones of Moscow, where they lived a semiferal existence. Because they mainly relied on people to throw out food, and less on handouts, they kept their distance from humans.

Now, old factories are being transformed into shopping centers and apartment blocks, so strays have become more avid and skillful beggars. They have developed innovative strategies, zoologists say, such as a come-from-behind ambush technique: A big dog pads up silently behind a man eating on the street and barks. The startled man drops his food. The dog eats it.

Key is the ability to determine which humans are most likely to be startled enough to drop their food. Strays have become master psychologists, says Andrei Poyarkov, 54, the dean of Moscow's stray-dog researchers. "The dogs know Muscovites better than Muscovites know the dogs."
Comfort in Crowds

Perhaps the biggest change, according to Mr. Vereshchagin, a protégé of Mr. Poyarkov, is that strays today hardly need to do anything to get food. One of their chief tactics, made possible by their increasing comfort in crowds, is simply to lie in a busy subway passage, where thousands of people pass by, and wait for someone to toss them something. The dogs get fed without even having to go to the trouble of nuzzling a leg.

Moscow today provides an environment of "unlimited resources," says Mr. Vereshchagin.

Mr. Vereshchagin strolls through a market area near a metro station, pointing out that even though there are now more strays than ever in Moscow, the dogs don't have a lean and hungry look. The leader of this area's dog pack, whose coat is dirty-white with black patches, rises from a nap, stretches lazily, and lopes off to a butcher shop. He stands outside for just a few seconds before a meaty bone is tossed at his feet. He carries it off, but just nibbles at it.

In fact, many dogs ignore discarded morsels, because the animals are so sated they can afford to be finicky, says Mr. Vereshchagin.

Unlike the strays he studies, Mr. Vereshchagin can't be so picky. The city has provided funding only for sporadic dog censuses, the last one in 2006, which estimated the population of stray dogs at about 26,000. So Mr. Vereshchagin, who has yet to finish his thesis, makes ends meet by training people's pets and working as a part-time paramedic.

Adaptations by individual dogs have added up to a dramatic shift in canine culture. Begging is a submissive activity, so today there are fewer all-out interpack wars, which sometimes used to last for months, according to Mr. Poyarkov. Within packs there are more stable social hierarchies that allow the whole group to prosper.

Still, there are occasional attacks on human beings, like one in April in which a 55-year-old man was killed by a pack of strays living in a rambling and overgrown park. Mr. Vereshchagin says he doesn't have firsthand information about this attack, but says that dogs living in forested areas aren't as familiar with people and are more likely to aggressively defend their territory.
Reignited Controversy

The death has reignited a controversy. Even while the city has allocated the equivalent of $63 million mainly to build animal shelters and carry out related programs, some people are calling for a return to the Soviet practice of culling strays.

Still, many Muscovites appear to enjoy, or at least tolerate, the dog population. The vast majority of homeless dogs go out of their way to avoid antagonizing people, says Mr. Vereshchagin. Even pooping in the metro is rare, he says.

Many Muscovites feed the strays and build simple winter shelters for them. Older people particularly seek companionship in Russia's new capitalist economy, which can be ruthlessly dog-eat-dog.

And strays form part of the city's character. When a disturbed fashion model several years ago stabbed to death a gentle stray that lived at the Mendeleyevskaya metro station, horrified celebrities and ordinary city residents raised money and erected a bronze statue of the dog, Malchik. One of novelist Mikhail Bulgakov's most beloved stories, "Heart of a Dog," features a stray named Sharik who takes human form as a slovenly proletarian.

Moscow has done almost as much adapting to the new culture of dogs as the dogs have done. A strong animal-rights lobby is part of that. Ilya Bluvstein, leader of Fauna, an animal-defense organization affiliated with Russia's Green Party, warns of potential corruption in the city's proposed shelter program. Groups that win the contracts, he fears, will take money to house dogs but actually kill them to cut expenses and fatten profits.

Meanwhile, in a metro station, three dogs nap. One of them rises, wanders a few steps to some discarded potatoes, sniffs, nibbles, then goes back to sleep. There will be more and better food later.

MEAT FOR SEX

FROM Geekologie via BBC:

"In a move that proves that chimps have created a much awesomer society than we have, researchers have discovered that males will trade meat to females in return for regular sexy times. And apparently the NOMs for PEWs exchange program is completely legit in their advanced legal system!
This is a long-term exchange, so males continue to share their catch with females when they are not fertile, copulating with them when they are.

"What's amazing is that if a male shares with a particular female, he doubles the number of times he copulates with her, which is likely to increase the probability of fertilising that female."

Yow yow! Is all this Animal Planet talk making anyone else in here steamy? I swear, meat for sex, that's even better than a handful of $20's! Now, where can I rent a monkey suit this far from Halloween? Also, hot wings. I'm gonna need hot wings."

Original Paper from Cristina Gomes and Christophe Boesch from the MPI-EVA published in PLoS ONE:Gomes CM, Boesch C (2009) Wild Chimpanzees Exchange Meat for Sex on a Long-Term Basis. PLoS ONE 4(4): e5116. doi:10.1371/journal.pone.0005116

Update from Northern DRC

Check out Cleve Hicks' report on his work with the chimpanzees from Bili, Aketi and surrounding areas in Northern DRC on the Wasmoeth Wildlife website. There are three e-books (around 50 pages each) of amazing images and heart wrenching details about the bushmeat crisis and mining activities in Northern DRC. Cleve has included information about the chimp surveys he has been conducting and the orphan chimpanzees that he has been confiscating (when he can), as well as many other aspects of his work in the area.
Despite the seemingly large number of chimps in Norther DRC, Wasmoeth Wildlife is the only NGO working there, so I encourage you to support them and Cleve by visiting their site.

More complex tool use from the Goualougo chimpanzees


from BBCnews:
'Armed' chimps go wild for honey By Rebecca Morelle (Science reporter, BBC News)

Cameras have revealed how "armed" chimpanzees raid beehives to gorge on sweet honey.

Scientists in the Republic of Congo found that the wild primates crafted large clubs from branches to pound the nests until they broke open.

The team said some chimps would also use a "toolkit" of different wooden implements in a bid to access the honey and satisfy their sweet tooth.

The study is published in the International Journal of Primatology.

Crickette Sanz, from the Max Planck Institute of Evolutionary Anthropology in Leipzig, Germany, said: "The nutritional returns don't seem to be that great.

"But their excitement when they've succeeded is incredible, you can see how much they are enjoying tasting the honey."

Honey monsters

Chimps' love of honey and their ingenuity at accessing it are well known amongst primatologists - previous studies have revealed how the great apes can fashion sticks to dip into or prise open nests.

But until now, nobody realised how prevalent the beehive-bashing behaviour was amongst chimpanzees in the Goualougo Triangle in the Congo Basin.

Dr Sanz said: "It seems these chimps in central Africa have developed more sophisticated techniques for getting at the honey than populations in eastern and western Africa - maybe it is some kind of regional feature."

Perhaps for obvious reasons, the chimps avoided bee species that sting, targeting the hives of stingless bees instead.

Dr Sanz told the BBC: "But these nests are tough to get into - they can be at the top of the forest canopy, at the end of a branch - and the chimps will go up there and hang at all sorts of precarious angles to get to the honey, using these clubs in any way that they can to access it."

The video footage, which was filmed by the researchers over four years, revealed the chimps' sheer determination to get at the sweet stuff.

Dr Sanz explained: "Nobody knew they would pound over 1,000 times to get to the honey.

"Sometimes it could take several hours - they would start in the morning at around 1000, then take some rests, and then finish up at about 1400 or 1500 in the afternoon.

"It is quite physically challenging - in the videos you can see how large those pounding clubs are - some weigh over a kilogram."

The primatologists also found that the Congo chimps' tool use was more sophisticated than previously thought.

David Morgan, a co-author on the study from the Wildlife Conservation Society and Chicago's Lincoln Park Zoo, said: "One of the most exciting aspects is that they are using multiple tools to access the honey that is in these hives.

"They have a tool kit ready when they go for honey.

"They will have large pounding clubs and they'll use those to hammer the hives.

"And if that doesn't do, if the holes are too small, then they'll access them using smaller, thinner dipping wands. And they are also using smaller sticks for leverage to get better access to the hive."

The researchers also said that once the chimps had spotted and then crafted a suitable club from a branch, by pulling off unwanted twigs and leaves with their teeth or hands, they would set it aside for later use.

Dr Morgan said: "They cache them in the canopy."

Last week, the same team also reported how Goualougo Triangle chimps were crafting fishing rods with a brush-tipped end to fish for termites, and the scientists say there is still much to learn about tool use in these chimps.

However, they told the BBC that the chimps' future was uncertain, as the primates and their habitat were under threat.

Dr Morgan said: "These beehives are found in tree species that are exploited for logging, so this could be a direct affect we have on their behaviour, their feeding and their conservation."
