Adaptation in the Feeding of Predatory Snails- Eric Sanford
One of the most important mentors of my undergraduate career has been Dr. Eric Sanford, professor of Evolution and Ecology at UC Davis and invertebrate zoologist extraordinaire. This summer, I have been a research assistant for a project with Ph.D. student Emily Longman and Eric, examining the adaptation of predatory snails along the West Coast. I'm excited to share the background for that project here! First: what is adaptation? Evolutionary adaptation (or, just adaptation) is the process in which the environment favors organisms with traits that increase their survival or reproductive success. These are often long-term changes, occurring over multiple generations. Individuals can acclimate to changing environmental conditions during one lifetime, but these changes are not genetic and will not be passed down to their offspring. Local adaptation occurs when one species is spread over an environmental gradient, where individuals may need different characteristics to be success...
