Summary: This study aims to: 1) use genetics and otolith (ear bone) microchemistry to determine if differences exist between collections of Arctic cisco (herring) made from tributaries of the Mackenzie River (Canada) and the Colville River (Alaska) and 2) use differences to identify population-of-origin of fish caught in the Colville River subsistence fishery. Approximately 60 Arctic cisco will be colle...

Summary: The primary objective of the fieldwork is to collect small samples of seed from grass species in six primary Genera: Festuca, Poa, Deschampsis, Leymus, Elymus and Alopecurus. Other species may be collected. Wild mustard species (Crucifer species) will also be collected. The collections will be compared visually and genetically to other collections of the same or closely related species from Alaska...

Licensed Year(s): 2006
Summary: The main activities in this program are: 1) forming a project steering committee involving industry, aboriginal groups and government; 2) identifying plant species suitable for revegetation; 3) developing practices for commercial production; and 4) identifying employment opportunities. Seed collection will be carried out in late August through to mid-September. Sites will be accessed by boat an...

Summary: The objectives of this research are: 1) to gather baseline data on size, age structure, fecundity (egg number per female), growth and mortality for lake trout in the study area; 2) to determine if lake trout are genetically distinct between basins of Great Bear Lake; and, 3) to determine the extent of movements by lake trout in Great Bear Lake by using molecular genetics. Field crews will be tr...

Principal Investigator: Gillespie, Lynn J.
Licensed Year(s): 2003 2000
Summary: This research will study variation among arctic plants (bluegrasses, alkali grasses, arctic poppies, arctic mustards) to better define species so that arctic plants may be more easily identified, and to better understand the origin and evolutionary relat...

Principal Investigator: Ballantyne, James
Licensed Year(s): 1998
Summary: The project will develop new, improved lines of arctic charr for the aquaculture industry by sampling arctic charr from sites throughout the Canadian arctic, characterizing the charr physiologically and genetically, and selectively breeding for traits desirable for hatchery culture (improved survival at higher temperatures and salinities). Genetic characterization will facilitate future stock iden...

Licensed Year(s): 1997 1995 1994
Summary: We plan to collect living plants, 6-10 plants of each species from each collection site. In addition, several plants of each species will be pressed and dried as voucher specimens to be used to check the identification. Photographs of the plants and their habitats will be made in the field and will be used for both research and teaching purposes. Upon our return to Ottawa the plant material wil...

Principal Investigator: Schwert, Donald P.
Licensed Year(s): 1995 1992
Summary: The sample of arctic-alpine ground-beetles will be collected under rocks and by pitfall traps (dixie cups placed in 8 cm diameter drilled holes) in the tundra habitat. All rocks will be replaced exactly and pitfall trap holes refilled with their soil plugs. No chemicals will be used in any of the trapping or collecting. Specimens will be analysed using DNA techniques which include RLPF's and PC...

Principal Investigator: Rode, Andris
Licensed Year(s): 1995
Summary: The study requires the subject to swallow a harmless "marker" substance (similar to cough syrup) at bedtime, followed by the collection of subject's total urine output over the next 8-12 hours. The urine will be analysed to see how well the subject's body metabolised or used the marker and whether the subject is a "good" or "poor" drug metaboliser. Blood samples will be taken to determine the gene...

Principal Investigator: Hebert, Paul D.N.
Licensed Year(s): 1994 1992
Summary: The research involves the use of helicopters with floats to sample the animal life present in lakes on the Melville Peninsula and northwestern Baffin Island. Most of our work will concentrate on the capture of zooplankton, small animals which foram an important part of the diet of young fish. After the collections are made, the samples are taken back to the Igloolik labratory, where they are sor...
