Sweaty cows may not sound like the most exciting company, but in a warming world, researchers can’t get enough of them.

Gray whales that spend their summers feeding in the shallow waters off the Pacific Northwest coast have undergone a significant decline in body length since around the year 2000, a new Oregon State University study found.

Following decades of decline, even fewer birds will darken North American skies by the end of the century, according to a new analysis by scientists at the University of Illinois Urbana-Champaign.

A study conducted by Brazilian researchers affiliated with São Paulo State University (UNESP), the Federal University of São Carlos (UFSCar) and the Federal University of Viçosa (UFV) has shown how three pesticides widely used by farmers in Brazil – imidacloprid, pyraclostrobin and glyphosate – affect native stingless bees of the species Melipona scutellaris. Whether they are used singly or combined, the pesticides impaired the bees’ ability to move about and weakened their defenses.

What species live in this coral reef, and are they healthy? Chemical clues emitted by marine organisms might hold that information. 

Late last year federal officials discovered the carcass of a mule deer buck near Yellowstone Lake in a remote region of Yellowstone National Park.

New research has connected warming ocean temperatures to higher Pacific salmon abundance in the Canadian Arctic, an indicator that climate change is creating new corridors for the fish to expand their range.

A new study offers first-time insights into three emerging climate innovations to safeguard or increase the carbon naturally captured by ocean and coastal ecosystems: rapid interventions to save the Great Barrier Reef, satellite-tracked kelp beds in the deep ocean, and seagrass nurseries in the United Kingdom. 

Winters can be tough on managed honey bee colonies, with beekeepers in the United States reporting that one-third of their colonies die each winter.

Burrowed into streambeds and rarely moving for their decades-long lifespans, freshwater mussels are biomonitors, meaning they indicate how clean their environment is, according to Penn State researchers.
