Dr. Julius A. Ellrich, Postdoctoral Fellow
|
Marine Ecologist I am examining predator-prey interactions, predator nonconsumptive effects on prey populations, trait-mediated indirect interactions and the function of foundation species in benthic communities. For my research, I am using rocky intertidal organisms as model systems. Recently, I started to investigate benthic-pelagic coupling along the Atlantic coast of Nova Scotia, Canada and biological invasions on the Pacific coast of Hokkaido, Japan. Enjoy my website.
