Social networking, even between competing species, plays a much bigger role in ecology than anyone previously thought, according to three biologists at the University of California, Davis. “There’s mounting evidence that different species pay attention to each other in the wild, especially if they share predators,” said Mike Gil, postdoctoral researcher at UC Davis. “The…

A team of Princeton ecologists took advantage of a rare opportunity to study what happens to an ecosystem when large carnivores are wiped out. “Large carnivores play a critical, and disproportionate, role in their ecosystems, and their populations are declining worldwide,” said Justine Atkins, a graduate student in ecology and evolutionary biology at Princeton. “However,…
