The already-rare Stone’s sheep of the Yukon is 20 per cent less common than previously thought, according to new research by University of Alberta biologists.

When rains fell on the arid Atacama Desert, it was reasonable to expect floral blooms to follow. Instead, the water brought death.

Not all polar bears are in the same dire situation due to retreating sea ice, at least not right now.

A contagious facial cancer that has ravaged Tasmanian devils in southern Australia isn't the first place one would look to find the key to advancing cell therapies in humans.

In an unusually early start to the sea turtle cold-stun season, we’ve seen 44 sea turtles--42 live Kemp’s ridleys, one dead Kemp’s ridley, and one dead green--wash up on Massachusetts beaches before November 5.

A new Institute for Marine and Antarctic Studies (IMAS)-led study has found that Antarctic krill are resilient to the increasing acidification of the ocean as it absorbs more C02 from the atmosphere due to anthropogenic carbon emissions.

Hurricane Florence’s floodwaters and Hurricane Michael’s storm surge caused obvious devastation to natural areas, but a subtler set of harms is harder to see.

A shift in home range by a handful of bird species along an obscure ridge in the Peruvian Andes might once have seemed like sleepy stuff, even to ecologists. Instead, it made headlines last month when researchers reported that the birds’ uphill push for cooler terrain has already resulted in population losses for most species and the probable extirpation of five species that were common at the top of the ridge just 33 years ago.

Loom-sensitive neural circuits characterized in previous lab studies are shown to underlie complex evasive behaviors observed in a natural environment.

Study shows that simulating a clock shift of six hours causes hatchling Blanding’s turtles to shift their course, demonstrating that the sun is central to their navigational compass
