'Dark Matter of the Biosphere' deals with agriculturally important bacteria

Bert Eardly, professor of biology at Penn State Berks, will present "Dark Matter in the Biosphere" as part of the 2007-2008 Division of Science Colloquium at 1:10 p.m. Friday, Sept. 21, in 123 Luerssen Building. This lecture is free to the public. Light refreshments will be served.

His talk will address the scientific community's recent recognition of the many different types of genetic bacteria that exist. His research involves the use of non-isotopic DNA sequence-based analyses to investigate how evolutionary forces (mutation, selection, recombination and genetic drift) influence the genetic structure in naturally occurring populations of soil bacteria. His current research involves collaborations with scientists from the USDA, as well as scientists in England, Finland, China and New Zealand.

Eardly earned his doctoral degree in crop science from Oregon State University, and a master's and bachelor's degree in agronomy from The Ohio State University.

The Division of Science Colloquium features Penn State Berks faculty who conduct research on a wide variety of topics. Upcoming events will include a lecture on "The Accelerating Universe" by Ruth Daly, professor of physics, on Friday, Oct. 19, in 123 Luerssen Building.
