The fate of emperor penguins is largely tied to sea ice, making them particulary vulnerable to warming.

Scientists have linked the decline in Arctic sea ice to the emergence of a deadly virus that could threaten marine mammals in the North Pacific, according to a study from the University of California, Davis.

Red deer on a Scottish island are providing scientists with some of the first evidence that wild animals are evolving to give birth earlier in the year as the climate warms.

Monarch numbers have declined about 82% over the last 23 years, and road mortality can significantly contribute to their dwindling numbers.

New genetic research has identified fin whales in the northern Pacific Ocean as a separate subspecies, reflecting a revolution in marine mammal taxonomy as scientists unravel the genetics of enormous animals otherwise too large to fit into laboratories.

Mitch Aide, a tropical ecologist based in Puerto Rico, thinks we should listen to the earth a lot more than we do now — and not just listen to it, but record and store its sounds on a massive scale. 

Research highlights that mercurcy concentrations in fish cannot be predicted by emissions inventories alone.

Birds come in an astounding array of shapes and colours. But it’s their physical prowess—like a bald eagle’s incredible ability to soar—that captivates human imagination.

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.
