Tropical forest birds, which tend to have wings that are short and round relative to their body length and shape, are more sensitive to habitat fragmentation than the long, slender-winged species common in temperate forests, according to an international collaboration that included scientists from Oregon State University.

Tiny foxes — each no bigger than a five-pound housecat — inhabiting the Channel Islands off the coast of Southern California were saved from extinction in 2016. 

Arctic ground squirrels are unique among mammals. 

Heat stress not only afflicts fish in uncomfortably warm waters.
