Malaria Spike Linked to Amphibian Die-Off

Dozens of species of frogs, salamanders and other amphibians quietly disappeared from parts of Latin America in the 1980s and 2000s, with little notice from humans, outside of a small group of ecologists. Yet the amphibian decline had direct health consequences for people, according to a study from the University of California, Davis. 

Fall Is Best Time to Clean Nest Boxes for Barn Owls

When it comes to American barn owls, forget spring cleaning. 

The best time of year to clean out nest boxes to ready them for breeding pairs is the fall months of September through November, according to research out of the University of California, Davis, that analyzed nearly a century of banding and other records. 

Eric Post: Arctic Awe and Anxiety

UC Davis polar ecologist Eric Post has kept a close eye on Arctic Greenland for nearly 30 years, documenting changes to the warming landscape and the plants and animals who call it home. 

In the classroom environment, he’s seen climate change create a different shift among students — one in which climate anxiety is an unavoidable and increasingly frequent reality. 

Peter Moyle: Fish by Fish, Bird by Bird

Peter Moyle is widely considered the “godfather of California fish biology.” The UC Davis professor emeritus has been conducting native fish surveys here for more than 50 years. He also played a major role in restoring Yolo County’s beloved local stream, Putah Creek.

Amanda Frazier: Holding Kindness

Amanda Frazier studies young polar fish — species with no colder place to go as the planet warms. A Ph.D. candidate in the Graduate Group in Ecology at UC Davis, she travels to Antarctica to learn how these vulnerable fish use sea ice and how they adjust their bodies and behaviors to cope with climate change. She’s thought a lot about what humans may have to learn from them about dealing with stress. 

Growing Cereal Crops With Less Fertilizer

Researchers at the University of California, Davis, have found a way to reduce the amount of nitrogen fertilizers needed to grow cereal crops. The discovery could save farmers in the United States billions of dollars annually in fertilizer costs while also benefiting the environment.

The research comes out of the lab of Eduardo Blumwald, a distinguished professor of plant sciences, who has found a new pathway for cereals to capture the nitrogen they need to grow.

UC Davis Student Pursuing Ph.D. in Hydrologic Sciences Wins Award

UC Davis student Laura Garza Díaz, who is pursuing a Ph.D. in hydrologic sciences, has been selected as this year’s recipient of the Neal Van Alfen and James MacDonald Graduate Student Award. She’s being recognized by the College of Agricultural and Environmental Sciences’ Graduate Education Committee for her demonstrated leadership and original research that supports the college’s mission to serve agriculture, the environment and human health and development.

California’s 2020 Wildfire Season

Just over 9,900 wildfires burned about 4.3 million acres in 2020. That’s more than twice the previous record of acres burned in California. Yet it is about average compared to burn rates likely experienced before Euro-American settlement, according to a study from the University of California, Davis, that summarizes the 2020 fire season and examines its drivers.
