Geneticists exploring the dark heart of the human genome have discovered big chunks of Neanderthal and other ancient DNA. The results open new ways to study both how chromosomes behave during cell division and how they have changed during human evolution.
In a new study, UC Davis postdoctoral researcher Didem Sarikaya and her colleagues analyzed egg-laying strategies of 65 different Hawaiian Drosophila species and found that egg-laying capacities diverged in response to their unique environments, which directly affected the number of cells involved in each species’ ovarian development.
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.
Scientists have successfully sequenced the coast redwood and giant sequoia genomes, completing the first major milestone of a five-year project to develop the tools necessary to study these forests’ genomic diversity.
For the past three summers, Professor Peter Wainwright and students have journeyed to the National Museum of Natural History’s Museum Support Center to collect data from preserved specimens in the National Fish Collection. In total, they've generated a dataset on 6,000 species and 16,000 individual specimens.
Determining how the planet’s plants will respond to changing environments is a monumental task, but thanks to a grant from the NSF, Assistant Professor Jennifer Gremer and colleagues will investigate how environmental factors influence the germination of California wildflowers.
