TITLE: Stable isotopes reveal the trophic ecology and interactions by oceanic predators
Abstract: The feeding habits and foraging areas of marine predators determine their ecological roles in ecosystems and the strength of interspecific trophic interactions (e.g., competition). Yet, such information is often challenging to obtain due to limited sampling opportunities, especially when it concerns populations inhabiting the high seas. Dr. Genyffer Troina will talk about her research investigating the trophic ecology and interactions of oceanic predators from the South Atlantic and the North Pacific using carbon (ẟ13C) and nitrogen (ẟ15N) stable isotopes.
Bio: Dr. Genyffer Troina is a postdoc fellow at the Institute for the Oceans and Fisheries, University of British Columbia, investigating salmon food webs in the high seas. She completed her Ph.D. in 2019, in a co-tutelage between the Universidade Federal do Rio Grande (Brazil) and Vrije Universiteit Brussel (Belgium). Her research focuses on the feeding ecology and trophic interactions of marine predators and their food webs using stable isotopes.
