Graham Coop, professor of evolution and ecology and director of the Center for Population Biology, has been elected to the American Academy of Arts and Sciences for his exceptional contribution to his field. Coop is one of nearly 250 new members announced by the academy on April 23.

How Are They Biting? High Speed Video Reveals Unexpected Jaw Movements in Reef Fish

Andy Fell — May 05, 2025 - 5:20pm

Some reef fish have the unexpected ability to move their jaws from side to side, biologists at the University of California, Davis have discovered. This ability – which is rare among vertebrate animals – allows these fish to feed rapidly and efficiently on algae growing on rocks. The work is published May 5 in Proceedings of the National Academy of Sciences.

Can Citizen Science Be Trusted? New Study of Birds Shows It Can

Platforms such as iNaturalist and eBird encourage people to observe and document nature, but how accurate is the ecological data that they collect?

Fish Teeth Show How Ease of Innovation Enables Rapid Evolution

Andy Fell — February 26, 2025 - 8:00am

It’s not what you do, it’s how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, according to new work by biologists at the University of California, Davis, who studied how teeth in certain fishes evolved in response to food sources and habitats.

Their work was published Feb. 26 in Nature.

Genetics of Alternating Sexes in Walnuts

The genetics behind the alternating sexes of walnut trees has been revealed by biologists at the University of California, Davis. The research, published Jan. 3 in Science, reveals a mechanism that has been stable in walnuts and their ancestors going back 40 million years — and which has some parallels to sex determination in humans and other animals.

Can Corals Be Saved?

It takes a strong constitution to be a coral researcher these days. These vibrant underwater ecosystems are beset by all manner of challenges in the 21st century, from bleaching events and pollution to storm surges and overfishing. But there’s good news on the way for coral conservation.

Invisible Anatomy in the Fruit Fly Uterus

Andy Fell — October 25, 2024 - 11:06am

You have likely not spent much time thinking about the uterus of the fruit fly, Drosophila melanogaster. But then, neither have most scientists, even though Drosophila is one of the most thoroughly studied lab animals. Now a team of biologists at the University of California, Davis, has taken the first deep look at the Drosophila uterus and found some surprises, which could have implications not just for understanding insect reproduction and potentially, pest control, but also for understanding fertility in humans.

Fighting Climate Change with Bee-utiful Pollinator Gardens
