To inform pest management techniques and fight threats like Citrus Greening disease, Walter Leal and his colleagues use reverse chemical ecology to identify sex pheromones in insects. From Brazil to Japan to Davis, Calif., Leal's research path has been unique.
In the last year, the Young Scientist Program has engaged roughly 1,100 students across the San Joaquin and Sacramento counties, bringing science education with a flair to underserved and poverty-stricken communities in the region.
In a study appearing in Science, researchers show that the pesticide imidacloprid, which has been sold in the U.S. since 1994, disrupts bumblebee (Bombus impatiens) nest behavior, causing reduced growth in exposed colonies.
Utilizing nearly 45 years of butterfly population field data, a new study published in Climate Change Responses reveals how recent record-setting temperatures and drought conditions affected butterfly populations at various elevations in Northern California. And the results are surprising.
In a study appearing in Genome Biology and Evolution, Assistant Professor Santiago Ramirez, Department of Evolution and Ecology, and postdoctoral researcher Julie Cridland provide a genetic snapshot of the state’s honey bee populations, defining how the species has changed over the past 105 years.
