Funding opportunity


Primate Conservation, Incorporated (PCI) is a nonprofit foundation founded to fund field research that supports conservation programs for wild populations of primates. Priority will be given to projects that study, in their natural habitat, the least known and most endangered species. The involvement of citizens from the country in which the primates are found will be a plus. The intent is to provide support for original research that can be used to formulate and to implement conservation plans for the species studied.

PCI will grant seed monies or provide matching grants for graduate students, qualified conservationists, and primatologists to study rare and endangered primates and their conservation in their natural habitat. All appropriate projects will be considered, but the regions of current interest are Asia and West Africa.

Not Just Nuts and Berries for These Hominids


20061114083447-2006110911.jpg


By Ann Gibbons
ScienceNOW Daily News
9 November 2006

The robust australopithecines of South Africa are often described as failed humans, having died out 1 million to 1.4 million years ago. Researchers believe their high-fiber, low-nutrient diets might have been too specialized to allow them to cope with a changing environment. A new report in tomorrow's issue of Science challenges this assumption, however, arguing that these close cousins of humans were much more culinarily adventurous than thought.

With their huge molars and massive jaw muscles, australopithecines have been portrayed as nutcrackers who crunched their way through seeds, nuts, and pulpy fruits. As Africa grew cooler and drier, however, these critical fall-back foods were hard to come by, supposedly leading to the hominid's downfall.

To test this theory, a team of American and British researchers studied the teeth of four individuals of Paranthropus robustus (also known as Australopithecus robustus) from the Swartkrans Cave in South Africa. The team scanned the teeth with a sensitive laser, which did not destroy the teeth but etched them lightly enough to free carbon gases long trapped in the enamel. Because different plants absorb atmospheric carbon dioxide differently, the researchers were able to see what types of vegetation the hominids ate based on the ratio of carbon isotopes in their teeth.

Their cuisine included a mix of tropical grasses and sedges, along with woody fruits, shrubs, and herbs, according to the findings. What's more, carbon samples from ridges laid down like tree rings in a single tooth revealed that the hominids switched between these diverse plants, depending on the time of year. The pattern held, regardless of when the hominids lived. Although the specimens date back to about 1.8 million years ago, each individual's lifetime was probably separated by thousands or tens of thousands of years, indicating that Paranthropus robustus was quite capable of dealing with changes in climate or different habitats. "We didn't expect to see as much variability as we found," says lead author Matt Sponheimer of University of Colorado at Boulder. "It was quite a surprise."

The new method is a huge improvement over old isotopic studies that required anthropologists to drill--and destroy--teeth to sample carbon, like prehistoric dentists, says paleoanthropologist Fred Grine of the Stony Brook University in New York. "Sponheimer's taken the analysis of carbon isotopes in fossils to a new level of sophistication," he says, adding that he hopes that fossil teeth--and diets--of earlier hominids can also be studied with the new nondestructive method.

Did evolution make our eyes stand out?

Researchers test ‘cooperative eye’ hypothesis in humans and apes


By Ker Than
LiveScience
Updated: 7:57 p.m. ET Nov. 8, 2006

For humans, the eyes are more than just windows to the outside world. They are also portals inward, providing others with glimpses into our inner thoughts and feelings.

Of all primates, human eyes are the most conspicuous; our eyes see, but they are also meant to be seen. Our colored irises float against backdrops of white and encircle black pupils. This color contrast is not found in the eyes of most apes.

According to one idea, called the cooperative eye hypothesis, the distinctive features that help highlight our eyes evolved partly to help us follow each others' gazes when communicating or when cooperating with one another on tasks requiring close contact.

In a new study that is one of the first direct tests of this theory, researchers from the Max Planck Institute for Evolutionary Anthropology in Germany looked at what effect head and eye movements had on redirecting the gaze of great apes versus human infants.

In the study, a human experimenter did one of the following:

  • Closed his eyes, but tilted his head up toward the ceiling
  • Kept head stationary while looking at the ceiling
  • Looked at the ceiling with both head and eyes
  • Kept head stationary while looking straight ahead
  • Results showed that the great apes — which included 11 chimpanzees, four gorillas and four bonobos — were more likely to follow the experimenter's gaze when he moved only his head. In contrast, the 40 human infants looked up more often when the experimenter moved only his eyes.

    The findings suggest that great apes are influenced more by head than eyes when trying to follow another's gaze, while humans are more reliant on eyes under the same circumstances.

    The study, led by Michael Tomasello, will be detailed in an upcoming issue of the Journal of Human Evolution.

    The small things
    Kevin Haley, an anthropologist at the University of California at Los Angeles, who was not involved in the study, told LiveScience he thinks the cooperative eye hypothesis is quite plausible, especially "in light of research demonstrating that human infants and children both infer cooperative intentions in others and display cooperative intensions themselves."

    Comparisons of human eyes to those of other primates reveal several subtle differences that help make ours stand out. For example, the human eye lacks certain pigments found in primate eyes, so the outer fibrous covering, or "sclera," of our eyeball is white. In contrast, most primates have uniformly brown or dark-hued sclera, making it more difficult to determine the direction they're looking from their eyes alone.

    Another subtle aid that helps us determine where another person is looking is the contrast in color between our facial skin, sclera and irises. Most apes have low contrast between their eyes and facial skin.

    Humans are also the only primates for whom the outline of the eye and the position of the iris are clearly visible. In addition, our eyes are more horizontally elongated and disproportionately large for our body size compared to most apes. Gorillas, for example, have massive bodies but relatively small eyes.

    The cooperative eye hypothesis explains these differences as traits that evolved to help facilitate communication and cooperation between members of a social group. As one important example, human mothers and infants are heavily reliant on eye contact during their interactions. One study found that human infants look at the face and eyes of their caregiver twice as long on average compared with other apes.

    Clue to our humanity
    Other ideas have also been proposed to explain why humans have such visible eyes. For example, white sclera might signal good health and therefore help signal to others our potential as a mate.

    Or, as one other recent study suggested, visible eyes might be important for promoting cooperative and altruistic behavior in individuals that benefit the group. The study, conducted by Haley and Daniel Fessler, also at UCLA, found that people were more generous and donated more money if they felt they were being watched — even if the watchful eyes were just drawings resembling eyes on a computer screen.

    Tomasello and his team note in their paper that "these hypotheses are not mutually exclusive, and highly visible eyes may serve all of these functions."

    If correct, the cooperative eye hypothesis could provide a valuable clue about when we became the social beings that we are. “It would be especially useful to know when in evolution human's highly visible eyes originated, as this would suggest a possible date for the origins of uniquely human forms of cooperation and communication,” Tomasello and colleagues write.

    Lizards have personalities too, study shows

    They may be cold-blooded, but some lizards have warm personalities and like to socialise, a new study shows.

    A behavioural study reveals that lizards have different social skills: some are naturally inclined to join large groups while others eschew company altogether. The discovery of reptilian personality types could help ecologists better understand and model animal population dynamics, say the researchers involved.

    Scientists define "personality differences" as consistent behavioural differences between individuals across time and contexts. But there is a need for more research on these differences in wild animals, says Julien Cote of the Pierre and Marie Curie University in Paris, France. "Psychologists have explored the considerable range of non-human personalities like sociability, but mostly on domesticated animals," he says.

    Scent of another

    Cote and colleagues captured wild pregnant common lizards (Lacerta vivipara), and as soon as the offspring were born they were exposed to the scent of other lizards, to test their reactions. Over the next year the team monitored the newly born creatures to see how much time each spent in different areas of their enclosure.

    Lizards that showed an aversion to other scents at an early age were more likely to flee highly populated areas of the enclosure, Cote's team found. These lizards were described as "asocial". In contrast, those that had been initially attracted to other scents often left sparsely populated areas of the enclosure to seek out areas of higher population density.

    Understanding these personality differences in wild animals could give ecologists a more nuanced view of population dynamics, Cote says. "When studying and modelling how populations function, it is necessary to consider different kinds of individuals reacting differently to the environment rather than a unique behavioural response for all individuals."

    Other experts agree that personality types could help explain why some animals might be more reluctant to leave a group and explore new turf. "If you have a personality by definition you are constrained," says ecologist Jason Jones of Vassar College in Poughkeepsie, New York, US.
