Maize is one of the world’s most widely grown crops. It is used for both human and animal foods and holds great cultural significance, especially for indigenous peoples in the Americas. Yet despite its importance, the origins of the grain have been hotly debated for more than a century. Now new research, published Dec. 1 in Science, shows that all modern maize descends from a hybrid created just over 5000 years ago in central Mexico, thousands of years after the plant was first domesticated.
Jay Stachowicz, a professor in the Department of Evolution and Ecology, has been named the interim director of the Coastal and Marine Sciences Institute (CMSI). Stachowicz succeeds the institute’s founding director, Rick Grosberg, a distinguished professor emeritus of evolution and ecology who retired from the university earlier this year.
Many mammals, from domestic cats and dogs to giant pandas, use scent to communicate with each other. A new study from the University of California, Davis, shows how domestic cats send signals to each other using odors derived from families of bacteria living in their anal glands. The work was published Nov. 8 in Scientific Reports.
Beds of eelgrass (Zostera marina) form an important habitat in coastal regions throughout the northern hemisphere, crucial to many fish and other species and storing vast amounts of carbon. A new study published July 20 in Nature Plants shows that eelgrass spread around the world much more recently than previously thought, just under a quarter-million years ago. The results have implications for how eelgrass could be affected by a changing climate.
Peter Wainwright, a Distinguished Professor and Chair of the Department of Evolution and Ecology, has been honored with the 2023 Joseph S. Nelson Lifetime Achievement Award in Ichthyology. Conferred by the American Society of Ichthyologists and Herpetologists (ASIH), the award recognizes exceptional contributions to the realm of fish biology and aquatic ecosystems.
Wainwright received the award in honor of a distinguished career marked by groundbreaking research, transformative education and dedicated service to his field.
Elena Suglia, a soon-to-graduate Ph.D. candidate in the Population Biology Graduate Group, has spent her time at Davis tackling the “inextricably intertwined issues” of environmental protection, environmental justice, and equity.
In recognition of her leadership in working at the intersection of science and public policy, Suglia was awarded the 2023 Emerging Public Policy Leadership Award from the American Institute of Biological Sciences.
In the College of Biological Sciences, principles of diversity, equity and inclusion are guiding principles. As such, an array of special DEI-related programs led by graduate students, each of whom was awarded a Graduate DEIJ Leader Fellowship for the 2022-23 academic year, will culminate in an open house event highlighting their achievements from 1:00-3:00pm on June 8, in Walker Hall.
In testing the genetic material of current populations in Africa and comparing against existing fossil evidence of early Homo sapiens populations there, researchers have uncovered a new model of human evolution — overturning previous beliefs that a single African population gave rise to all humans. The new research was published today, May 17, in the journal Nature.
“Do relatives make good neighbors?” UC Davis Distinguished Professor Emerita Sharon Strauss will answer this question and provide additional thoughts on species diversity in natural communities at the spring Emeriti Lecture in person and online on Monday, April 17, at 3pm.
