As wildflowers go, the mountain jewelflower is demure, clever and quietly unbreakable. It has spread across many of California’s iconic landscapes, from Sonoma wine country to the oak-dotted foothills, even over the Sierra Crest, where snow covers the ground during winter.

A kestrel swoops to grab a smaller bird on the wing and eats it, right in front of a group of men in the garden at California Health Care Facility, or CHCF, a prison in Stockton, where the garden has become both a thriving ecosystem and a science classroom for people incarcerated there. As the feathers fly, UC Davis researcher Laci Gerhart pulls out a bird guide and shows the incarcerated men how to identify the bird by its size and coloration, noting that kestrels are North America’s smallest raptor and one of the few that are sexually dimorphic. 

On her first day of graduate school, Karolina Zabinski rose at 4:00am. She spent the day on the muddy shores of Tomales Bay, collecting eelgrass for a survey of aquatic plant diseases. These ribbon-like seagrasses are common along the California coast and form knee-high meadows that undulate in the water.

As she scooped plants out of the mud, she noticed how much they varied from place to place. Eelgrass (Zostera marina) at one site had long, slender roots. But just a few miles north, the roots were short and bushy. 

The National Academy of Sciences has elected Jeffrey Ross-Ibarra, professor in the Department of Evolution and Ecology at University of California, Davis, as a member. His election was announced April 28.

Ross-Ibarra is one of 120 members and 25 international members elected this year in recognition of distinguished and continuing achievements in original research. Membership in the academy is considered one of the highest honors a scientist can achieve.

Why are there so many species of coral reef fish? According to a new study, it’s because about 50 million years ago, some fish figured out how to bite food from hard surfaces. 

Evolution doesn’t proceed at an even pace—species evolve in jumps and spurts, followed by lulls. These periods of rapid diversification usually occur after a dramatic environmental change or upheaval, or when a lineage develops a new “innovation” that allows them to use a previously inaccessible resource. For fish, the ability to feed from a hard surface was one such innovation.

Anya Brown and Rachael Bay are featured in a new National Geographic article exploring their research on coral reef resilience in the Cook Islands. Working in a remote, makeshift field lab, the UC Davis scientists are studying why some corals survive rising ocean temperatures while others bleach and die. Their work combines genetics and community ecology, investigating how relationships among corals, algae, and microbes may help reefs recover—and even “rescue” more vulnerable corals.

Four faculty, two each in CBS departments and graduate groups, are among this year’s recipients of the Academic Senate and Federation top awards. They are in a cohort of 15 academics across various disciplines throughout the university to be recognized.

The awards cite the impact these academics have had on their fields, on UC Davis students and on the broader community through public service.

Long ago, on a faraway Aleutian island, a pair of rare beaked whales got stranded. One was saved by biologists and swam back out to sea. The other perished and its skeleton now hangs inland, thousands of miles from home.

Coral reefs make up less than 1% of ocean habitat but are home to at least 25% of marine species. These incredibly biodiverse ecosystems are increasingly threatened by human actions, including anthropogenic climate change.

The college is very pleased to have welcomed four new faculty during the 2025 calendar year. Joining the Departments of Microbiology and Molecular, Evolution and Ecology, and Molecular and Cellular Biology, each new faculty member adds expertise and breadth to the college’s research and teaching portfolio.
