Both of the food webs above contain the same number of species. Which one best describes how fish interact in nature? The graphs on the right also contain the same number of species and same prey, but have very different depictions of how fish species partition prey. Which one is most probable? How do they alter our interpretations of predator-prey interactions? How do they affect linked aquatic-terrestrial ecosystems?
If these questions interest you, you’re in luck! I have an opening for a MS or Ph.D. student to study stage-structured predation and cross-ecosystem subsidies in the Department of Biology at the University of South Dakota. The project will involve field sampling for fishes along the Missouri National Recreational River, along with mesocosm experiments in a modern 22,000 square-foot artificial stream facility at USD (Experimental Aquatic Research Site: ExARS). Along the way, students will also learn Bayesian data analysis in classes and research.
The position will start in Fall 2018 and is fully funded as a 12-month RA for two years at ~$22,000 per year with full tuition and fee waiver, along with funds for research and conference travel. Support beyond two years would be from a mix of internal 9-month TA’s and RA’s with summer support pending funding. Interested students shouldapply to the Graduate School at USD and should be prepared to submit an application that includes GRE scores, statement of interest, transcripts, three reference letters, and other materials as required by the Graduate School. Informal inquiries about the positions are welcome: Jeff.Wesner@usd.edu.
