A ground squirrel with cheeks stuffed with nuts, seeds or grains, is a common sight. But a new study provides the first evidence that California ground squirrels also hunt, kill and eat voles. The study, led by the University of Wisconsin-Eau Claire and the University of California, Davis, is the first to chronicle widespread carnivorous behavior among squirrels.

Not all cattle are the same when it comes to grazing. Some like to wander while others prefer to stay close to water and rest areas.

Recognizing those personality differences could help ranchers select herds that best meet grazing needs on rangelands, leading to better animal health and environmental conditions, according to a new paper from the University of California, Davis, published in the journal Applied Animal Behaviour Science.

Researchers using puzzle boxes, rain sticks and papier-mâché balls are studying captive gray wolves at the Oakland Zoo and the California Wolf Center to evaluate personality and problem-solving skills of the endangered animals.

The novel research out of University of California, Davis, which also incorporates hundreds of hours of video and observational surveys, is seeking to shed new light on the lives of gray wolves, how they interact as part of a pack and respond to strange, new things

Researchers at the University of California, Davis, have found that people may not recognize that their dog is stressed when exposed to common household noises. While it’s well established that sudden loud noises, such as fireworks or thunderstorms, commonly trigger a dog’s anxiety, a new study finds even common noises, such as a vacuum or microwave, can be a trigger. The study was published in Frontiers in Veterinary Science. 

Do you ever wonder why sometimes one, lone cow stands munching grass on a hillside while her fellow cattle graze in groups below?

Animal behavior experts at UC Davis do, and their curiosity may shed light on one of the most critical economic and ecological questions in rangeland management. How can we encourage more cattle to roam?

Social networking, even between competing species, plays a much bigger role in ecology than anyone previously thought, according to three biologists at the University of California, Davis. 

“There’s mounting evidence that different species pay attention to each other in the wild, especially if they share predators,” said Mike Gil, postdoctoral researcher at UC Davis. “The theory of ecology has lagged behind.”
