Precipitation patterns, along with temperature, dictate where tropical forests are distributed around the world.

Astronauts face a very difficult challenge in space. In microgravity, their muscles and bones weaken over time.

A virus affecting wood frog tadpoles throughout the eastern United States is offering scientists a rare opportunity to investigate the role of environmental factors in the spread of infectious disease.

The fast-warming Arctic has started to transition from a predominantly frozen state into an entirely different climate, according to a comprehensive new study of Arctic conditions.

Honey bees heavy with pollen and nectar foraged from wildflowers on Utah’s Uinta-Wasatch-Cache National Forest collide with tall grass and tumble to the ground. 

A Texas A&M AgriLife Research and USDA project looks to honey bee diets to strengthen immunity to disease pathogens and reduce population losses.

Miniature fitness trackers for lobsters and devices to monitor the quality of their shipping conditions are being prototyped as part of an initiative to reduce stress points and improve survival in the lobster supply chain for the Maine lobster industry.

Sparrows show increased stress when exposed to more numerous and more severe winter storms, says a Western study that tested the songbirds’ resilience to the effects of climate change.

By studying the wood-cutting behaviour of ancient beavers that once roamed the Canadian high Arctic, an international team of scientists has discovered that tree predation – feeding on trees and harvesting wood – evolved in these now-extinct rodents long before dam-building.

It’s a rare privilege to welcome newborn bison calves into the world. It’s even more rare when those calves are the fruit of your labour.
