capuchin

The immune performance of wild capuchin monkeys declines when the animals experience higher temperatures, and younger monkeys seem to be particularly vulnerable to heat, according to a University of Michigan study.

These tools may help them get at many questions surrounding capuchin monkey behavior, including how they decide whether to cooperate or compete with one another while they are interacting in their natural world.

She currently studies cooperation and other social behaviors in capuchin monkeys.

If a species is a generalist, able to adapt to its circumstances — think about the racoons or deer in your suburban neighborhood, or the capuchin in this study — it may need less help.

Another study — this one published last year in the journal Current Biology — involved scientists performing a magic trick known as the "French drop effect" in front of three types of monkeys: common marmosets, Humboldt's squirrel monkeys and yellow-breasted capuchin monkeys.
