Global Warming Cycles Threaten Endangered Primate Species

ScienceDaily (Oct. 29, 2009) — Two Penn State University researchers have carried out one of the first-ever analyses of the effects of global warming on endangered primates. This innovative work by Graduate Student Ruscena Wiederholt and Associate Professor of Biology Eric Post examined how El Niño warming affected the abundance of four New World monkeys over decades.

Wiederholt and Post decided to concentrate on the way the oscillating weather patterns directly and indirectly influence plants and animals in the tropics. Until the research by Wiederholt and Post, this intricate network of interacting factors had rarely been analyzed as a single system. "We know very little about how climate change and global warming are affecting primate species," explains Wiederholt. "Up to one third of primates species are threatened with extinction, so it is really crucial to understand how these changes in climate may be affecting their populations."
