Bacteria of the Flies: Tracing the Spread of Disease-Controlling Wolbachia

March 09, 2018
In a study appearing in Current Biology, Michael Turelli, distinguished professor of genetics in the Department of Evolution and Ecology, and his colleagues traced the spread of closely related Wolbachia across Drosophila fly species. They found that while the flies evolutionarily diverged tens of millions of years ago, their Wolbachia bacteria diverged only tens of thousands of years ago.

It’s Good to Be Rare, for Some Species

December 12, 2017
When most people think of rare species, they think of endangered ones that humans have caused to be rare through habitat loss, poaching, climate change and other disturbances. But some species have always been rare — occurring in small densities throughout their range — throughout their evolutionary history.

Long-Lived: Remembering Melvin Green, A UC Davis Genetics Pioneer

December 11, 2017
Melvin M. Green, distinguished professor emeritus of molecular and cellular biology, was a geneticist and member of the National Academy of Sciences. Green co-founded the historic UC Davis Genetics Department (now part of the Department of Molecular and Cellular Biology). He passed away on Tuesday, Oct. 24, 2017, at the age of 101.

Fly Genomes Provide Clues to Parallel Evolution

November 27, 2017
In a paper appearing in PLOS Genetics, Professor David Begun, Department of Evolution and Ecology in the UC Davis College of Biological Sciences, compared the genomes of different fly species to understand how genes—both within and between species—evolve adaptively. He found that two fly species that diverged from a common ancestor some 50 million years ago, exhibited parallel evolution on both short- and long-term timescales.

Peter Wainwright Recognized with Faculty Research Lecture Award, Academic Senate's Highest Honor

May 01, 2017
There’s a distinctly fishy feel to Peter Wainwright’s office. Books on a side table have titles like this one: Basslets, Dottybacks and Hawkfishes. Fish skeletons and skulls adorn boxes and bookshelves. A painting of tropical ocean fish hangs on the wall. Wainwright will be talking about all this and more on Tuesday, May 9, when he presents the annual Faculty Research Lecture. The lecture is the highest award presented by the faculty of the University of California, Davis, to one of their colleagues
