Dr. Brian Hayden

I am an aquatic ecologist currently working with the Stable Isotopes in Nature Laboratory at University of New Brunswick, Fredericton. My research covers all trophic levels from zooplankton to aquatic mammals although primarily focused on fish. I am particularly interested in interactions between resident and invasive species, examining how the trophic ecology of invasives allows them to take hold in new environments and how resident species respond to the presence of a new competitor. I employ a variety of research techniques including field surveys stomach content and stable isotope analyses, geometric morphometrics and molecular genetics to investigate these topics and more….

Since 2014 I have served as Social Media Editor for the Fisheries Society of the British Isles. Follow us on Twitter @TheFSBI and Facebook, www.facebook.com/TheFSBI
