Among the Academies: Studying How Plants Adapt

How can plants adapt to their environment, and how will they be able to adapt to climate change? Those are among the biggest questions Johanna Schmitt has sought to answer during her career as a plant geneticist and evolutionary ecologist.

Plants Seek Friendly Environments Rather Than Adapt

As jewelflowers spread into California from the desert Southwest over the past couple of million years, they settled in places that felt like home, according to a new study from the University of California, Davis. The work, published July 1 in Proceedings of the National Academy of Sciences, shows that the ability of plants and animals to adapt to changing climates might be more limited than it appears.

Fish "Beauty Salons" Offer Insight into How Microbes Move Within Reefs

Where do you go when you’re a fish and you need a skincare treatment? Coral reefs contain natural “beauty salons,” lively social hubs of activity where fish “clients” swim up and wait to be serviced by smaller fish cleaners. The little cleaners dart under and around their much bigger clients — even entering their mouths — cleaning their scales of bacteria and parasites like a team of car washers servicing a Buick. Sometimes cleaners even rub against their clients, providing a soothing massage.

Course Inspires Next Generation of California Naturalists

Nobody knew that badgers were inhabiting an ecosystem near Davis until recently — and finding them is the kind of discovery that would excite any seasoned biologist. But that’s not who identified the rare species just last year. It was spotted by undergraduates in Laci Gerhart’s popular “Wild Davis” course (EVE 16), who have also had rare glimpses of ringtails and other species. 

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

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.

Fish Teeth Show How Ease of Innovation Enables Rapid Evolution

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.
