Native bees in the Oregon Coast Range are diverse and abundant in clearcut areas within a few years of timber harvest but their numbers drop sharply as planted trees grow and the forest canopy closes, research by Oregon State University shows.

It epitomizes the Great Plains in spirit and in form: a 2,000-pound tank on hooves, cloaked in shaggy winter-tested coat, capped by horns acting as warning and weapon.

Killer whales (also known as orcas) are intelligent predators. While it’s known that killer whales in the Pacific Northwest exploit widely different food types, even within the same region, we know much less about the feeding habits of those found throughout the North Atlantic. 

Deteriorating habitat conditions caused by climate change are wreaking havoc with the timing of bird migration.

Like many animals in the far north, snowshoe hares change their coats from brown to white each autumn.

During August 2019, more than 40,000 tourists visited Hawai`i’s Molokini island to snorkel or dive. 

As the climate changes, many species are expected to adjust where and how they live. 

Marine predators have expanded their ranges  into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.

Enock Bwambale stopped at the lip of the dying glacier, its blunted nose arcing steeply down to scoured rocks, then shouted up to his fellow guide Uziah Kule that the ice was too sheer to descend on foot. 

Larvae produced by black rockfish, a linchpin of the West Coast commercial fishing industry for the past eight decades, fared better during two recent years of unusually high ocean temperatures than had been feared, new research by Oregon State University shows.
