The UC Davis Department of Entomology and Nematology has booked associate professor of biology Tim Linksvayer of the University of Pennsylvania for a seminar on “Genomic Signatures of Social Evolution in Social Insects" on Wednesday, Oct. 4.
The seminar, open to all interested persons, takes place from 4:10 to 5 p.m. in 122 Briggs Hall, Kleiber Hall Drive.
"Eusociality in ants, bees, wasps, and termites is a major evolutionary innovation, yet the genomic basis of sociality is largely unknown," Linksvayer says. "I will discuss recent and ongoing research in my lab focused on elucidating the genetic basis and evolution of social traits and social systems in ants and honey bees."
"We study the genetic and behavioral underpinnings of complex social systems in order to understand how these systems function and evolve," he says on his website. "We are especially interested in how social interactions affect genetic architecture and trait evolution."
Access his website and you'll see a pharaoh ant. "We use social insects, such as the pharaoh ant, as a study system because they are exemplar social systems and are also well-established models for research in social evolution, behavioral genetics, and collective behavior."
This is the second of the fall seminar series hosted by the department. The seminars began Sept. 27 and will conclude Dec. 6. Assistant professor Rachel Vannette is coordinating the seminars.

The UC Davis Department of Entomology and Nematology has announced the list of speakers for the fall seminars. Agricultural entomologist and seminar coordinator Christian Nansen said the topics include everything from soapberry bugs to monarchs.
Instead of the previous noon-hour seminars, however, there's a change in the time: they're from 4:10 to 5 p.m. on Wednesdays in Room 122 of Briggs Hall, Kleiber Hall Drive.
Doctoral candidate Meredith Cenzer will speak on "Ecological and Evolutionary Interactions Between Soapberry Bugs (Jadera Haematoloma) and Their Host Plants" at the next UC Davis Department of Entomology and Nematology seminar, set from 4:10 to 5 p.m., Wednesday, Oct. 5 in 122 Briggs Hall. This is her exit seminar.
Soapberry bugs are a classic evolutionary example of how rapidly insects can switch hosts, adapting from a native to an invasive plant, she says.
Her newly published UC Davis research shows that soapberry bugs have not only lost adaptations to their native host plant but are regionally specializing on an invasive host. (Read about her latest publication here.)
