Summer REU positions

From Susan Mazer - a Professor in EEMB:

This a great (and well-paying) opportunity for two motivated and NSF is particularly interested in funding students from under-represented groups.

Evolutionary Genetics, Ecological and Physiological Research: The Mazer lab recently received a five-year grant from the National Science Foundation to study the evolution of different pollination mechanisms (or “mating systems”), along with the evolution of physiological performance and life history in a group of California native wildflower species (in the genus Clarkia). This group of wildflowers is unusual in that the ability to self-fertilize (that is, to produce seeds without the assistance of crosspollinating insects) has evolved multiple times from insect-dependent, outcrossing relatives. Two subspecies of the species Clarkia xantiana (shown above) illustrate the kind of floral trait that is associated with the evolution of the ability to self-fertilize: smaller flowers with pollen that is “dumped” right onto the adjacent stigma. Our research group develops and tests a variety of genetic and ecological predictions and hypotheses concerning the causes and the consequences of the evolution of selffertilization. If you are selected as an REU student for the summer of 2010, you would help us to measure the physiological stress responses (anti-oxidant production) that these plants exhibit throughout the flowering season. Much of the activity would be conducting chemical assays in our lab at UCSB, but you would also have the opportunity to assist with field work in June and July, visiting our remote and rugged field sites in the southern Sierra Nevada.
