African carnivores face numerous threats from humans. So, it’s a fair assumption that the presence of more humans automatically equates to decreases across the board for carnivores. New research led by Matthew Farr and Elise Zipkin shows that’s not always the case.
When it comes to advancing social status, it’s not what you know, it’s who you know – for humans and spotted hyenas alike. Eli Strauss and Kay Holekamp show that hyenas that form strong coalitions can gain social status, which can have lasting benefits over many generations.
Monarch butterfly numbers have been dropping precipitously for more than two decades.

The American Ornithological Society recently named Catherine Lindell the 15th editor in chief of The Condor: Ornithological Applications, one of two peer-reviewed journals published by the American Ornithological Society.
