Genetics of endangered African monkey suggest troubles from warming climate

e drill."

The base pairs examined came from 54 samples of DNA. Base pairs are made up of adenine, thymine, guanine and cytosine. While DNA is the blueprint for life, examining the sequences of these chemicals also provides a roadmap into any organism's past. "Looking at its modern genetic diversity, you can infer changes in past population size," Ting said.

In the mid-Holocene, temperatures across equatorial Africa were hotter and dryer, with a reduction of forest cover that the drill need for survival. The ecology of the region also includes multiple other species found only there. The research, Ting said, is among emerging work focusing on past climate conditions in equatorial areas. Many studies have been done on conditions in both temperate and arctic regions.

The findings carry conservation implications, Ting said. "We could see many of these equatorial forests becoming very arid. Forest will be lost as vegetation changes to adapt to dryer conditions. Our findings show that this type of animal, which already is very much endangered because of hunters, would not be able to deal with the level of climate changes that could be coming."

What is needed to protect this little understood species are measures that reduce the destruction of the forest habitat and step up protection against poachers, said Ting, who is co-director of the UO's molecular anthropology group and a member of the UO Institute of Ecology and Evolution and UO Institute of Cognitive and Decision Sciences.

"Professor Ting's research is helping us push the boundaries of our knowledge about wildlife habitats through genetic studies of these rare and endangered monkeys," said Kimberly Andrews Espy, vice president for research and innovation. "The University of Oregon is a leader in developing new technologies for analyzing and mapping DNA in organisms and crops. Studying the genetics of these rare drill could lead to new approaches to conservation."
