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

In a new study published in Citizen Science: Theory and Practice on March 28, UC Davis researchers show that citizen science data from iNaturalist and eBird can reliably capture known seasonal patterns of bird migration in Northern California and Nevada — from year-round residents such as California Scrub-Jays, to transient migrants such as the Western Tanager and Pectoral Sandpiper.

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.

A mussel bed along Northern California’s Dillon Beach is as healthy and biodiverse as it was about 80 years ago, when two young students surveyed it shortly before Pearl Harbor was attacked and one was sent to fight in World War II.

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.

The work of 12 early-career faculty members will get a boost as this year’s class of Hellman Fellows. They will receive grants ranging from $16,000 to $49,000, for a total of $330,000 awarded.

Their work covers a wide range of topics, from the educational experiences of Venezuelan immigrants to a wireless device that monitors for seizures.

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.

At UC Davis, undergraduates have opportunities to dive into independent research at the Bodega Marine Laboratory (BML) through the EVE Scholars Program. Students like Aishu Santosh and Caroline Donohew are pushing the frontiers of marine science while discovering a lot about themselves in the process.

Jeffrey Ross-Ibarra, Department of Evolution and Ecology, and Marina Ellefson, Department of Molecular and Cellular Biology, receive 2024 College of Biological Sciences faculty awards...  The college announced the recipients of the 2024 CBS Faculty Teaching and Research Awards.

Each year, the college’s top graduating seniors are recognized for their outstanding achievements at an awards ceremony attended by friends, family, mentors and donors. This year’s graduating senior and university award recipients were honored for their academic excellence, commitment to fostering community, service to campus and their peers and for exceptional research efforts.  Kyle Elshoff, Evolution, Ecology and Biodiversity major, was awarded the College of Biological Sciences Undergraduate of the Year.

Longtime UC Davis academic coordinator Carole Hom, who retires this year after a quietly influential career, is so beloved that she has two nametags: one bearing her official title, and another with alternates—“Spiritual Leader” and “Chief Guru”—made for her by colleague Rick Grosberg, a distinguished professor emeritus of Evolution and Ecology.
