If you are in the Nashville area this Thursday, please join us at the
Radnor Lake State Natural Area Visitor's Center, 1160 Otter Creek Rd,,
Nashville for our monthly meeting starting at 7:15. p.m. We will gather at
7:00 p.m.
Dr. John Niedzwiecki, Professor of Biology at Belmont University, will
present his program "Using Comparative Landscape Genetics to Quantify
Interisland Gene Flow in Darwin's Finches". Dr. Niedzwiecki recently
worked on the migration of Darwin's Finches between islands in the
Galapagos, investigating connections with ecology as well as the
evolutionary consequences of migration. One assumption persistent over
the last 100 years is that speciation occurred, with birds effectively
isolated on different islands, allopathic speciation. His team was
interested if speciation may have occurred despite persistent gene flow
between islands. Dr. Niedzwiecki will present his data, and describe a
collecting trip to get a data set to test intraisland gene flow.
