Climate Change Could Shrink Oyster Habitat in California

August 05, 2019
Ocean Acidification Just One of Several Climate-Related Threats for Shellfish

Ocean acidification is bad news for shellfish, making it harder for them to form their calcium-based shells. But several other factors related to climate change could also make California bays less hospitable to shelled organisms like oysters, which are a key part of the food web.

To Explore or Exploit? Fishing Vessel Records Show Trade-offs

When making choices, people tend either to go with what they know or try something new. We experience this trade-off every day, whether choosing a route to work or buying breakfast cereal. But does one strategy have an advantage over another? Researchers decided to examine this question by looking at fishing boat captains, who face this choice again and again when deciding where to fish.

Treatments May Reduce Loss in Future Droughts and Bark Beetle Epidemics

Thinning forests and conducting prescribed burns may help preserve trees in future droughts and bark beetle epidemics expected under climate change, suggests a study from the University of California, Davis.

Study: ‘Remarkable’ Weather Becomes Normal Within a Few Years

What kinds of weather do people find remarkable, when does that change, and what does that say about the public’s perception of climate change? A study led by the University of California, Davis, examined those questions through the lens of more than 2 billion U.S. Twitter posts.  

How Climate Change Is Affecting Small Sierra Nevada Lakes

Spring Snowpack a Bigger Predictor of Lake Warming Than Air Temperature

Scientists at the University of California, Davis, are taking the temperature — and other measurements — of lakes of all sizes and shapes throughout the mountains of California to see how climate change is affecting them and what, perhaps, can be done about it.

USAID and UC Davis to Establish World's First Index Insurance Quality Certification in East Africa

September 05, 2018

High-quality agricultural index insurance has shown promise in promoting resilience among small-scale farmers who face a constant risk of drought and other weather-related shocks. However, despite decades of investments this tool has yet to achieve its broadest impact in part because of low-quality contracts that don’t reliably pay farmers for losses and that sometimes pay when there are none. 

Lichens Are Losing to Wildfire, Years After Flames Are Gone

August 09, 2018

As increasingly hot and severe wildfires scorch the West, some lichen communities integral to conifer forests aren’t returning, even years after the flames have been extinguished, according to a study from scientists at the University of California, Davis.
