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.
In a study appearing in Proceedings of the National Academy of Sciences, UC Davis researchers present a statistical method that—by virtue of providing a mathematical description of the relevant biological and technical processes associated with transcriptomic data—allows researchers to identify the expression state of genes.
Congratulations to Professor of Evolution and Ecology Sharon Strauss for winning the American Society of Naturalists’ Sewall Wright Award, which honors a senior and active investigator “promoting the conceptual unification of the biological sciences.”
The City Nature Challenge, a global event encouraging people to explore and record the natural world around them, returns to the Sacramento Region from April 24-27, albeit with a few changes due to the coronavirus pandemic.
Some species of fish, notably parrotfish and wrasses living on coral reefs, change their biological sex as they age, beginning life as females and later becoming functionally male. New work from the University of California, Davis, shows that this sequential hermaphroditism evolves when bigger males gain an advantage in reproductive success.
Recently, graduate students in Professor Eric Sanford's Scientific Filmmaking Seminar shared their films at the Ecology Film Festival. Now you can view all 11 films in one place.
Professor Art Shapiro predicted it: The cabbage white butterfly would be out this week, alerting his “posse” to their opportunity to win his annual Beer for a Butterfly contest — the prize going to the person who catches the first cabbage white of the new year.
Associate Professor Santiago Ramirez, Department of Evolution and Ecology, was among the 20th class of Chancellor's Fellows. This marks the 20th anniversary of the program that provides philanthropic support to exceptional early career faculty members.
In a study appearing in Proceedings of the National Academy of Sciences, UC Davis researchers used the staple plant model organism Arabidopsis thaliana, known commonly as the thale cress, to uncover the genetic mechanisms that control its seeds responses to chilly weather.
To attract a mate, male orchid bees collect scents from the environment to create the perfect aroma. In a study appearing in Nature Communications, UC Davis researchers link the evolution of sexual signaling in orchid bees to a gene that’s been shaped by each species’ perfume preferences
