High-severity wildfire is increasing in Sierra Nevada and Southern Cascade forests and has been burning at unprecedented rates compared to the years before Euro-American settlement, according to a study from the Safford Lab at the University of California, Davis, and its collaborators. Those rates have especially shot up over the past decade. 

Spring is the sweet spot for breeding songbirds in California’s Central Valley – not too hot, not too wet. But climate change models indicate the region will experience more rainfall during the breeding season, and days of extreme heat are expected to increase. Both changes threaten the reproductive success of songbirds, according to a study from the University of California, Davis. 

UC Davis researchers are providing more insight into how grape skins and seeds, which usually go to waste during the making of chardonnay wine, may be a valuable and healthful ingredient in new food products.

A review paper published by the Journal of Agricultural and Food Chemistry outlines how chardonnay marc can serve as a model for developing plant-based natural product food ingredients, and perhaps make upcycling agricultural byproducts relevant to other post-harvest processing scenarios.

UC Davis student Sophia Simon, who is pursuing a Ph.D. in ecology, has received a Quad Fellowship. She is part of the Fellowship’s first cohort of 100 exceptional science, technology, engineering and mathematics (STEM) graduate students. 

A team of UC Davis doctoral and undergraduate students have something to celebrate as the fall quarter comes to a close. UC Davis sent a team to the Region 6 (southwest) Collegiate Soil Judging Competition, where groups are scored on their ability to describe and classify soils and landscapes.

A solution to world hunger might start with boba and caviar.

Using an innovative process, engineers at UC Davis are growing “myco-foods” — small balls of edible fungi that can be processed into products like boba and lab-grown caviar with a wide range of textures, colors and flavors. These myco-foods, grown from the nutrients of agricultural byproducts like coffee grounds and almond hulls, provide an important new source of protein to feed the world.

People are increasingly trying to grow both food and clean energy on the same land to help meet the challenges of climate change, drought and a growing global population that just topped 8 billion. This effort includes agrivoltaics, in which crops are grown under the shade of solar panels, ideally with less water.

Now scientists from the University of California, Davis, are investigating how to better harvest the sun — and its optimal light spectrum — to make agrivoltaic systems more efficient in arid agricultural regions like California. 

An ordinary bus stop in Vallejo has a fresh new look. The local site got a makeover designed by UC Davis students Ashley Gear and Katie Wong, both seniors majoring in landscape architecture.

Solano County Transit (SolTrans), which runs the bus service in Vallejo, recently unveiled its newly transformed bus stop located at Gary Circle and Magazine Street. SolTrans chose the students’ design, which Gear and Wong created last spring for the “Plants in the City” course led by Assistant Professor Haven Kiers.

Bus stops, bike paths, sidewalks and other spots often overlooked in the community will become areas of beauty — for the sake of science. That’s the idea behind the Seed Pile Project, which asks community members from as far east as Sacramento and as far west as the East Bay to drop a pile of native wildflower seeds near their home or office and monitor the growth.

Viral communities across a grassland area are not uniform, and understanding viral dynamics could lead to better insight into how bacteria in soil will react to drought and other climate changes, according to research out of UC Davis.

Viruses can affect microbes, the food web, the carbon cycle and other ecosystem processes, including controlling bacteria.
