Please join us on February 22, 2013 at 4:00PM in Jonas 305 to listen to Dr. Kaius Helenrun, the Chair of the Biology Department at USD, speak about conservation genetics and evolution of endemic plants on California’s Channel Islands. Below is an abstract of Dr. Helenrun’s seminar.
California's Channel Islands, although small and close to the mainland, have a substantial proportion of endemic plant taxa. Many of these are very rare, owing partly to their narrow range but also to a long history of grazing by introduced herbivores. I have been studying over twenty rare plant taxa of San Clemente Island using a variety of molecular markers to document patterns of genetic variation and to infer evolutionary processes. In addition, my lab is conducting phylogeographic studies on two plant groups that have dispersed and differentiated on this near-shore island system.
