Evolution & Ecology

Deep evolution casts a longer shadow than previously thought, scientists report in a new paper published Aug. 1 in the Proceedings of the National Academy of Sciences.

Coral reefs are home to a spectacular variety of fish. A new study by biologists at the University of California, Davis, shows that much of this diversity is driven by a relatively recent innovation among bony fish — feeding by biting prey from surfaces. The work was published the week of July 25 in Proceedings of the National Academy of Sciences.

A new film is in the works with more than one UC Davis connection.

Weeping Rocks, a feature-length documentary that focuses on the role of insects in our ecosystem, spotlights the work of Professor Art Shapiro in the College of Biological Sciences and is produced by Jackii Chun ’10. The film is in production now and raising funds on Kickstarter.

Sharon Strauss, a Distinguished Professor emerita in the Department of Evolution and Ecology, was among the three UC Davis faculty who have been elected as members of the National Academy of Sciences. They are among 120 new members and 30 international members announced by the academy on Tuesday, May 3.

A complete sequence of the human genome has finally been published by an international consortium of scientists. The new reference genome fills in gaps left by earlier drafts, which will help researchers better understand genetic variation and how it can sometimes lead to disease.

Studies comparing animal genomes generally focus on the DNA sequence itself. A new study by researchers at the University of California, Davis shows how the three-dimensional scaffolding of chromosomes is related across several species of carnivores, offering a new approach of “comparative scaffotyping” that could be used to identify related genes across species and place them in context. The work, published the week of Feb.

Habitat conservation can help buy time for heat-sensitive species in the face of climate change – but it might also leave them in a trap by preventing them from adapting in time, according to a study from the UC Davis Bodega Marine Laboratory published late last year in the journal Ecology.

A study led by the University of California, Davis, has found significant differences in gut bacteria between Black and white women, even after accounting for their insulin sensitivity status. The study, published in PLOS ONE, is the first to focus on premenopausal Black and white women and to show such differences.

A global effort to map the genomes of all plants, animals, fungi and other eukaryotic life on Earth is entering a new phase as it moves from pilot projects to full-scale production sequencing. This new phase of The Earth BioGenome Project, or EBP, is marked with a collection of papers published this week (Jan. 17) in Proceedings of the National Academy of Sciences, describing the project’s goals, achievements to date and next steps.  

University of California, Davis, evolutionary biologist Rachael Bay has been awarded a 2021 Packard Fellowship in Science and Engineering by the David and Lucile Packard Foundation. The fellowship offers Bay, assistant professor in the Department of Evolution and Ecology, College of Biological Sciences, an opportunity to advance her work on the role of human action on evolutionary trajectories of species.
