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
UC Davis project scientist Kristin Aquilino directs the Bodega Marine Laboratory's white abalone captive breeding program. Last week marked the first time BML captive-bred white abalone were released to the ocean in hopes of saving the species.
As director of the Coastal and Marine Sciences Institute, Richard Grosberg oversees an interdisciplinary body that includes membership from the College of Biological Sciences, the College of Agricultural and Environmental Sciences, the College of Letters and Science, the College of Engineering, the School of Law, the School of Veterinary Medicine and the Graduate School of Management.
Sexual determination and differentiation work in myriad ways across the animal kingdom. In vertebrates, like mammals and fish, sexual determination leads to the development of either ovaries or testis. These organs then secrete hormones that go on to govern the sexual development of the rest of the organism’s body. Insects are a completely different beast.
Population Biology Ph.D. student Victoria Morgan uses genetics to understand how land crabs adapted to living on land. Her research has taken her all the way to Christmas Island, home to the annual Christmas lsland Red Crab migration.
The combination of a big population, good genes and luck helps explain how a species of fish in Texas’ Houston Ship Channel was able to adapt to what normally would be lethal levels of toxins for most other species, according to a study to be published May 3 in the journal Science.
