"When chimpanzees are portrayed as caricatures of humans, dressed up in silly outfits and so on, people think that chimps aren't endangered, aren't worthy of our conservation efforts,'' Ross said.
"I think these data show that there's probably effects we don't even imagine when people are watching those things and laughing,'' he said.
It's a hard habit to break, he acknowledges. He cites an American Association for the Advancement of Science ad that showed chimps dressed in hats while reading an issue of Science magazine. While the monkey depicted in a San Diego Zoo ad posted on YouTube is not a chimp, the creature is seen holding a suitcase at an airport waiting to board a jet.
"It's part of our culture, American and worldwide, to see chimpanzees in this way. With these stats, maybe we can get people to think of them differently,'' Ross said.
William Hoffmann of Chicago-based Animal Rentals Inc., which provides the Sun-Times' stock-picking monkey "Mr. Adam Monk'' as well as supplying animals for commercials, sees Ross' piece as the latest evidence of friction between zoos and private owners of exotic creatures.
"Zoos have a tendency to want no one to own animals but themselves -- they like exclusivity,'' Hoffmann said.
If we remember that they need to be preserved, can we enjoy them then?
Researchers say that few primates mate in a face-to-face position, known technically as ventro-ventral copulation; most primate species copulate in what's known as the dorso-ventral position, with both animals facing in the same direction. Besides humans, only bonobos have been known to frequently employ ventro-ventral mating positions. On a few occasions, mountain gorillas have been observed in ventro-ventral positions, but never photographed. Western gorillas in captivity have been known to mate face-to-face, but not in the wild, which makes this observation a noteworthy first.
REGENT’S PARK The tails of these silvery marmosets show up clearly as the monkeys’ coldest body part in this picture taken by a photographer using a thermal imaging technique at London Zoo.
While the warm parts of the marmosets’ bodies show up as red or yellow, the tails, which retain little warmth, appear green. The imaging technique has helped zookeepers to home in on the different tactics zoo animals use to conserve energy.
Male macaque monkeys pay for sex by grooming females, according to a recent study that suggests the primates may treat sex as a commodity.
"In primate societies, grooming is the underlying fabric of it all," Dr. Michael Gumert, a primatologist at the Nanyang Technological University in Singapore, said in a telephone interview Saturday.
"It's a sign of friendship and family, and it's also something that can be exchanged for sexual services," Gumert said.
Gumert's findings, reported in New Scientist last week, resulted from a 20-month observation of about 50 long-tailed macaques in a reserve in Central Kalimantan, Indonesia.
Gumert found after a male grooms a female, the likelihood that she will engage in sexual activity with the male was about three times more than if the grooming had not occurred.
Another cracker jack plan to handle the monkey problem in India. Now, they are going to train unemployed youths to capture moneys and sterilize them with lasers. Yes. Lasers. Sixteen year old boys are going to perform laser surgery on monkey testicles.
Here is a quote from the article that points out one obvious problem with this plan. Angry monkeys after botched surgeries.
"It is a ridiculous idea and what is worse, it will do nothing to contain the problem and probably make it worse," Chaudhuri said. "Can you imagine what having badly sterilized monkeys running around will do to the levels of aggression?"
Do we really need to consider turning everything upside down by considering the existence of a human ancestor for the apes? This suggestion definitely has the quality of blasphemy against religious doctrine. It just feels wrong and goes against our deeply held beliefs and understanding of the world.
However, this is exactly where the evidence leads
Although tool use is known to occur in species ranging from naked mole rats to owls, chimpanzees are the most accomplished tool users. The modification and use of tools during hunting, however, is still considered to be a uniquely human trait among primates. Here, we report the first account of habitual tool use during vertebrate hunting by nonhumans. At the Fongoli site in Senegal, we observed ten different chimpanzees use tools to hunt prosimian prey in 22 bouts. This includes immature chimpanzees and females, members of age-sex classes not normally characterized by extensive hunting behavior. Chimpanzees made 26 different tools, and we were able to recover and analyze 12 of these. Tool construction entailed up to five steps, including trimming the tool tip to a point. Tools were used in the manner of a spear, rather than a probe or rousing tool. This new information on chimpanzee tool use has important implications for the evolution of tool use and construction for hunting in the earliest hominids, especially given our observations that females and immature chimpanzees exhibited this behavior more frequently than adult males.
Female monkeys may shout during sex to help their male partners climax, research now reveals.
Without these yells, male Barbary macaques (Macaca sylvanus) almost never ejaculated, scientists found.
Female monkeys often utter loud, distinctive calls before, during or after sex. Their exact function, if any, has remained heavily debated.
Counting pelvic thrusts
To investigate the purpose behind these calls, scientists at the German Primate Center in Göttingen focused on Barbary macaques for two years in a nature reserve in Gibraltar.
The researchers found that females yelled during 86 percent of all sexual encounters. When females shouted, males ejaculated 59 percent of the time. However, when females did not holler, males ejaculated less than 2 percent of the time.
To see if yelling resulted from how vigorous the sex was, the scientists counted the number of pelvic thrusts males gave and timed when they happened. They found when shouting occurred, thrusting increased. In other words, hollering led to more vigorous sex.
Counting monkey pelvic thrusts is admittedly "quite weird, but it's science," researcher Dana Pfefferle, a behavioral scientist and primatologist at the German Primate Center, told LiveScience. "You get used to it."
