The jewelflower, a small California wildflower, may help scientists understand how more plants could survive changing weather patterns.

Scientists Dispute Hypothesis That Climate Change Will Unleash Massive Ag Pest Populations

Andy Fell — May 12, 2026 - 10:27am

The widespread hypothesis that climate warming will result in unprecedented agricultural pest populations and cause food insecurity worldwide is oversimplified, according to a new study by a team led by Mia Lippey, an entomologist at the University of California, Davis. But the study does indicate that pests fare better in warmer temperatures than their natural enemies, which researchers identified as a cause for concern.

Experiences in the first days and weeks of life can have a profound impact on humans — and birds. A new study led by Sage Madden, a graduate student in evolution and ecology at the University of California, Davis, shows how weather conditions and family dynamics affect the growth of barn swallow (Hirundo rustica erythrogaster) chicks.

Study Projects Plant Extinction Rates Through 2100

Katherine E Kerlin — May 07, 2026 - 11:00am

A 51�ԹϺ�� Davis study in Science found that 7% to 16% of global plant species studied face high risk of extinction by 2100 under current climate change projections.

Forest Fuel Treatments Reduce Wildfire Spread, Prevent $2.8 Billion in Damage

Amy M Quinton — May 07, 2026 - 11:00am

A 51�ԹϺ�� Davis study finds every dollar spent on forest fuel treatments saves $3.75 in wildfire damages.

Climate Change Increases Spillover Risk of Rodent-Borne Arenaviruses

Katherine E Kerlin — May 04, 2026 - 9:00am

Climate change is likely to drive rodent-borne arenaviruses into parts of South America that have never faced these diseases, putting new communities of people at risk, finds a study from the University of California, Davis.

For the study, published in the journal npj Viruses, scientists incorporated climate projections, shifting rodent populations and the risks of human infection into a model to offer an early risk projection for arenaviruses and other diseases in the next 20 to 40 years.

National Academy of Sciences Elects 51�ԹϺ�� Davis Maize Geneticist Jeffrey Ross-Ibarra

Andy Fell — April 29, 2026 - 8:45am

The National Academy of Sciences has elected Jeffrey Ross-Ibarra, professor in the Department of Evolution and Ecology at University of California, Davis, as a member. His election was announced April 28.

Ross-Ibarra is one of 120 members and 25 international members elected this year in recognition of distinguished and continuing achievements in original research. Membership in the academy is considered one of the highest honors a scientist can achieve.
