Arizona State University researchers have found that larger tropical stingless bee species fly better in hot conditions than smaller bees do. Larger size may help certain bee species better tolerate high body temperatures. The findings run contrary to the well-established temperature-size "rule," which suggests that ectotherms -- insects that rely on the external environment to...

In all animals, including humans, smell -- the oldest of the five senses -- plays a predominant role in many behaviors essential for survival and reproduction. It has been known since ancient times that animals react to odours.

A single mitochondrial DNA mutation common in animals could play a role in obesity and other health problems associated with a diet high in carbohydrates.

A new study by WCS, American Museum of Natural History, and other partners uses long term data on bear mortality to map high-probability hot-spots for human-bear conflicts. The authors say this is a critical tool for wildlife managers to reduce mortality of bears as they recolonize their former range in the Great Basin and in...

A substance in young mice's tears makes female mice more likely to reject male sexual advances. This research is part of ongoing efforts at the University of Tokyo to understand how animals communicate using chemicals called pheromones.
