Scientists collect valuable data on marine mammals, seabirds, and sea turtles during the first part of a survey off the southeast coast of the United States.

Burnout. It is a syndrome that is said to afflict humans who feel chronic stress.

Texas A&M researchers found that the small mammals are internally warmed by thermogenic leak from their skeletal muscle, which elevates their metabolic rate.

The confluence of the tiny San Pedro River and the much larger Gila was once one of the richest locales in one of the most productive river ecosystems in the American Southwest, an incomparable oasis of biodiversity.

A study in the Proceedings of the National Academy of Sciences led by Michael Moore at Washington University in St. Louis finds that dragonfly males have consistently evolved less breeding coloration in regions with hotter climates.

The Arctic is warming at approximately twice the global rate. 

In addition to sequencing the RNA of 30 yellow-banded worker bees, the researchers also used the sequence data to directly search for pathogens infecting the bumblebees.

Changes in the colour and intensity of light pollution over the past few decades result in complex and unpredictable effects on animal vision, new research shows.

"People don't come to Denali and other parks in Alaska to look at bumblebees, but they should,” says Jessica Rykken, entomologist for Denali National Park and Preserve. 

New findings suggest that abnormal ocean currents cause the occasional appearance of pelagic red crabs outside their native range.
