Julius A. Ellrich

Marine Ecologist
St. Francis Xavier University, Antigonish, Nova Scotia, Canada
I am examining predator-prey interactions, predator nonconsumptive effects on prey populations, trait-mediated indirect interactions and the function of bioengineering species in benthic communities by using intertidal organisms as model systems. Recently, I started to investigate benthic-pelagic coupling processes along the coasts of Nova Scotia, Canada. I can be reached at Prof. Dr. Ricardo Scrosati's Marine Ecology Lab at St. Francis Xavier University.
