Migratory Birds Track Climate Across the Year

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.

What is the Connection Between Genotype and Phenotype? Study Describes New Statistical Method to Identify Active and Inactive Genes from Transcriptomes

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.

Male Size Advantage Drives Evolution of Sex Change in Reef Fish

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.

Bumblebees Carry Heavy Loads in Economy Mode

Bumblebees are the big lifters of the insect world, able to fly back to the hive with almost their own body weight in nectar on board. A study published Feb. 5 in Science Advances shows how they do it — and that bees can show more flexibility in behavior than you might expect from a bumbling insect.

The Art-Science Loop: Creating Worlds with Evolution, Ecology and Biodiversity Undergraduate Megan Ma

Since enrolling at UC Davis nearly four years ago, undergraduate Megan Ma has lent her artistic talent to the Aggie community. She’s taught scientific illustration, provided artwork for the BIS 2C lab manual and currently works as a graphic designer for the Center for Leadership Learning, all the while taking classes and rotating through research labs.

VIDEO: Summers at the Bodega Marine Laboratory with UC Davis Marine and Coastal Sciences Major Michael Brito

Every summer, the UC Davis Bodega Marine Laboratory (BML) offers classes to undergraduate students interested in coastal and marine sciences. After hearing about the summer sessions from his friends, Michael Brito, a fourth-year majoring in marine and coastal sciences, knew he had to check out this life-changing experience.
