Research scientist

Jory Cabrol joined the Department of Fisheries and Oceans in November 2019 as a research scientist. Before to be a part of the research and conservation of marine mammals team. Dr. Cabrol was primarily interested on trophic interactions  and physiological conditions of arctic and subarctic zooplankton through the use of biochemical indicators such as fatty acids, lipids and stable isotopes. Currently, Jory uses his knowledge to the preservation species at risk including the St. Lawrence beluga population, but also baleen whales in the St. Lawrence. 

Current research and/or projects

Centre(s) of Expertise:

Dr. Jory Cabrol is a Research Scientist at Fisheries and Oceans Canada in Mont-Joli (Québec) with the Marin Mammal Research Division. His research focuses on characterizing beluga trophic interactions, diet and its evolution since 1930's. More specifically, his research focus on :

  • Determination and quantification of diet using trophic biomarker (eg, fatty acids and stable isoptopes).
  • Evolution of realized vs potential trophic niches in the actual context of climatic change and increasing human perturbation with a special focus on the last 30 years.
  • How temporal changes in the feeding specialization degree may affect inter-individual and inter-specific competition for share ressources in the St. Lawrence
  • The application, validation and development of trophic ecology theories and their application to marine mammal species.
