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

Smoothies can be a tasty and convenient way to get the important fruits and vegetables you need for a healthy diet. But is a banana and blueberry smoothie the best combo?

With an extendable pole fitted with a small camera, Alison Ke could get a clear view of the inside of a nest box, including one time when a small, green Pacific parrotlet laid eggs. Ke, who earned a Ph.D. in ecology from UC Davis, led a research project to find out how converting rainforest to farmland affects the habitat of birds who rely on tree holes, or cavities, for nesting.

In an increasingly diverse, multicultural world, adolescents struggle academically in multicultural environments if they don’t receive consistent and positive messages at school, home and among their peers about cultures that are not their own, a University of California, Davis, study suggests.

Nearly half of parents who relied on formula to feed their babies during the infant formula shortage last year resorted to potentially harmful feeding methods, according to a survey from researchers at the University of California, Davis. The study was published in the journal BMC Pediatrics. 

A group of researchers, which includes research affiliate Dr. John Trochet with the UC Davis Museum of Wildlife and Fish Biology, has been working for the past 10 years to collect evidence that the elusive ivory-billed woodpecker is still in existence.

Chickens provide one of the world's most popular animal proteins, with billions of birds grown every year for eggs and meat. Interpreting the farm animal’s genome is vital for understanding how genes control traits, such as growth, feed efficiency, reproduction and disease resistance.

As the climate changes, many species are expected to adjust where and how they live. Some are expected to seek cooler elevations as it warms, but what happens to species already at the top of a mountain? A study of squirrels living in California’s high-elevation Sierra Nevada indicates that climate is only one factor to consider when trying to predict where an animal will make its home in a changing world.  

The McCloud River redband trout, or O. mykiss calisulat, is newly identified as its own distinct subspecies of rainbow trout in a study from the University of California, Davis. It is the first newly identified subspecies of Pacific trout since 2008 and the youngest rainbow trout subspecies by more than 100 years.

California is home to four of the eight active soda taxes in the United States, but are these policies successfully decreasing the consumption of sugary beverages in these cities? New research out of UC Davis suggests that, in most cases, these soda taxes did not reduce retail sales.
