Research Description:
Dr. Gregory has been a research scientist at DFO since 2000. He has conducted research on fish nursery habitats for over 30 years, including 18 years investigating marine fish nursery habitat in marine coastal waters of Newfoundland. Bob investigates population-habitat linkages, habitat-mediated juvenile fish survival and recruitment, fish movement and habitat associations, cumulative effects of anthropogenic environmental change and compensation mitigation of habitat change. Bob is an Adjunct Professor of Biology at Memorial University of Newfoundland, where he has co-supervised and mentored 24 graduate students in the past decade, all of whom now work on aquatic ecology issues in various university, federal and provincial government research facilities, or in industry. He is the Director of the Centre of Expertise for Aquatic Habitat Research (CAHR).

  • Memorial University of Newfoundland
Centre(s) of Expertise:
  1. Eelgrass patch size and proximity to the patch edge affect predation risk of recently settled age 0 cod (Gadus)
  2. Fatty acid biomarkers in coldwater eelgrass meadows: elevated terrestrial input to the food web of age-0 Atlantic cod Gadus morhua.
  3. Decreased lipid storage in juvenile Atlantic cod (Gadus morhua) during settlement in cold-water eelgrass habitat
  4. Discrete spatial dynamics in a marine broadcast spawner: re-evaluating scales of connectivity and habitat associations in Atlantic cod (Gadus morhua) in coastal Newfoundland.
  5. Episodic downwelling predicts recruitment of Atlantic cod, Greenland cod and white hake to Newfoundland coastal waters
  6. Predictive analysis of scale-dependent habitat association: juvenile cod (Gadus spp.) in eastern Newfoundland. Estuar
  7. Prey selection by marine-coastal river otters (Lontra canadensis) in Newfoundland, Canada
  8. Size-selective predation by river otter (Lontra canadensis) improve refuge properties of shallow coastal marine nursery habitats
