Lichens Slow to Return After Wildfire

May 10, 2021
Frequent Fire Narrows Recovery Window for Lichens in Chaparral Shrublands

Lichen communities may take decades — and in some cases up to a century — to fully return to chaparral ecosystems after wildfire, finds a study from the University of California, Davis, and Stanford University. 

The study, published today in the journal Diversity and Distributions, is the most comprehensive to date of long-term lichen recolonization after fire.

Lawn in Main Thoroughfare Will Become Pastoral

Sheep will graze the University of California, Davis, Campus Gateway on Old Davis Road this week in an academic experiment to see if sheep can eat weeds and grass, fertilize and control pests as well as or better than using conventional landscaping methods.

Solar Development: Super Bloom or Super Bust for Desert Species?

May 03, 2021
Rare Desert Plants More Sensitive to Solar Development

Throughout the history of the West, human actions have often rushed the desert — and their actions backfired. In the 1920s, the Colorado River Compact notoriously overallocated water still used today by several Western states because water measurements were taken during a wet period.

Finding New Life for Wine-Grape Residue

Chardonnay Pomace May Be Rich in Health-Enhancing Compounds

California produces nearly 4 million tons of world-class wine each year, but with that comes thousands of tons of residue like grape skins, seeds, stems and pulp. What if scientists could harness that viticultural waste to help promote human health?

Report to State Outlines Policy Pathways to Meet the Zero-Carbon Time Crunch

Transportation is the largest source of greenhouse gas emissions in California. In order to achieve the state’s goals of carbon neutrality by 2045 and avoid the worst impacts of climate change, decarbonizing this sector is essential. But such a transition is unlikely to occur rapidly without key policy intervention. 

Water Talk Podcast Launches Season 2: ‘Drought Is Back!’

April 02, 2021

The UC Davis-affiliated podcast Water Talk launches its second season today, April 2. This season will focus on drought, a water issue at the top of many minds during this relatively dry rainy season. 

“In California, drought is not ‘if,’ it’s ‘when,’” said Water Talk co-host Faith Kearns, academic coordinator with the California Institute for Water Resources.

Feeding Cattle Seaweed Reduces Their Greenhouse Gas Emissions 82 Percent

March 17, 2021
New Long-Term Study Could Mean More Sustainable Burgers

A bit of seaweed in cattle feed could reduce methane emissions from beef cattle as much as 82 percent, according to new findings from researchers at the University of California, Davis. The results, published today (March 17) in the journal PLOS ONE, could pave the way for the sustainable production of livestock throughout the world.

When ‘Eradicated’ Species Bounce Back With a Vengeance

March 15, 2021
Lessons From a Failed Experiment Mark New Way Forward

Some invasive species targeted for total eradication bounce back with a vengeance, especially in aquatic systems, finds a study led by the University of California, Davis.

Migratory Birds Track Climate Across the Year

February 18, 2021

As climate change takes hold across the Americas, some areas will get wetter, and others will get hotter and drier. A new study of the yellow warbler, a widespread migratory songbird, shows that individuals have the same climatic preferences across their migratory range. The work is published Feb. 17 in Ecology Letters.

Arctic Shrubs Add New Piece to Ecological Puzzle

February 03, 2021
Implications for Carbon Exchange in a Warming, Drying Tundra

15-year experiment on Arctic shrubs in Greenland lends new understanding to an enduring ecological puzzle: How do species with similar needs and life histories occur together at large scales while excluding each other at small scales? The answer to this question has important implications for how climate change might shift species’ distributions across the globe.
