Comparison of Tissue and Plasma Fatty Acid Composition from Temperate and Arctic Marine Organisms
Principal Investigator: Glemet, Helene
Licenced Year(s): 1991 1990
Summary: The Researcher will collect blood/hemolymph and tissues from representative Arctic marine fish, echinoderm, crustacean and mollusc species. The fish will be netted and the invertebrates dredged. Samples will be analyzed for their fatty acid composition. A sample size of 6-8 individuals will be required from each species....


The Role of Latitude on Mating Systems in Notostraca
Principal Investigator: Straszynski, Elizabeth
Licenced Year(s): 1990
Summary: "Tadpole shrimp" (Notostraca) occur in ponds at all latitudes in Canada. Activity and behavior show differences between the sexes. Mating behaviour shows differences between the two latitudes already tested. Studies in southern and northern Manitoba (Portage la Prairie; Churchill) will be compared with those in the eastern Northwest Territories (Igloolik)....


To determine the productivity of the most important components of marine mammal food chains
Principal Investigator: Welch, Harold
Licenced Year(s): 1988
Summary: To study epontic algae and amphipods in Chesterfield inlet area; to determine dynamics of Si and N as essential nutrients; to sample stomach contents of hunter-killed seals for food habit analysis....


Licence #5142
Principal Investigator: Sprague, J. B.
Licenced Year(s): 1985
Summary: To collect samples of common amphipod crustaceans, microscopic crustaceans, and algae in order to measure their cadmium content....


Licence #5127
Principal Investigator: Boileau, Marc G.
Licenced Year(s): 1985
Summary: To continue investigations on the ecology and population genetics of crustacean zooplankton: to focus on the genetic diversity of the four major species of copepods inhabiting the freshwater ponds in the Arctic and the distribution and dispersal of these species since glaciation....


Licence #5060
Principal Investigator: Beaton, Margaret
Licenced Year(s): 1985
Summary: To take water samples from ponds for a better understanding of the ecology and population genetics of the freshwater cladoceran species, Daphnia pulex....


Licence #5026
Principal Investigator: Welch, Harold
Licenced Year(s): 1985
Summary: Epontic primary production, phytoplankton production, and subice amphipod production in the Barrow Strait area; work at the ice edges in Lancaster Sound, and summer chlorophyll distribution....


Licence #4094
Principal Investigator: Sprague, John B.
Licenced Year(s): 1984
Summary: To collect samples of common amphipod crustaceans, microscopic crustaceans, and algae in order to measure their cadmium content....


Licence #2796
Principal Investigator: Sprague, John B.
Licenced Year(s): 1982
Summary: To collect specimens of arctic cod (Boreogadus saida) and common amphipod crustaceans in order to examine cadmium in food-chains....


Licence #2467
Principal Investigator: Korczinski, Rita
Licenced Year(s): 1979
Summary: To conduct a study of the life cycle and habitat of the isopod, Mesidotea entomon (a small crustacean). The study will also include consideration of the isopod as a food source for fish. To determine the extent of isopods as a food source, fish samples will be taken for subsequent laboratory analysis....
