Integrated Management Planning in the Husky Lakes Area of the Inuvialuit Settlement Region.
chercheur principal:
Année(s) de permis: 2001 2000
Résumé: The research team will be based out of Tuktoyaktuk, and travel to Tuktoyaktuk from Inuvik will be by scheduled flight. No field camps will be used, and all transport in the field will be on foot or by boat. The study will be done through individual and group interviews, using maps and semi-directed interviews. Interviews will be taped, to facilitate data collection. Participation in the study i...


Flora of the Canadian Arctic Archipelago
chercheur principal:
Année(s) de permis: 2001 1999
Résumé: The research team will be based in Tuktoyaktuk, and travel by scheduled flight from Inuvik. No field camps will be used, and all transport in the field will be on foot. Data will be collected primarily through photographic documentation of both the plants of interest, and the typical environments in which these plants are found. A single voucher specimen of each plant photographed will be mainta...


Tuktoyaktuk Lake and Fish Habitat Survey
chercheur principal:
Année(s) de permis: 2001 2000
Résumé: The research team will conduct a lake and fish habitat survey, to identify which water bodies have the following characteristics: overwintering fish, lake depths greater than 3.5 feet and water quality conditions which are not suitable for overwintering fish. The research team will consist of 3 crews, 4 men/crew. Crews will receive their safety and sampling orientation in Tuktoyaktuk Harbour at ...


Genetic Diversity in the Biota of Arctic Lakes
chercheur principal:
Année(s) de permis: 1997
Résumé: Our research will involve the survey of zooplankton communities in lakes and ponds of the Mackenzie Delta area (Inuvialuit private lands). Samples will be collected by either wading in ponds or by towing at net behind a float equipped helicopter. Samples will be frozen in liquid nitrogen, and subsequently examined for genetic variation. Our work aims to establish the species diversity of zoopla...


Hybridization and genetic variation in arctic grasses: molecular, morphological and ecological evidence.
chercheur principal:
Année(s) de permis: 1997 1995 1994
Résumé: 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...


Biology, ecology and cold tolerance of arctic insects
chercheur principal:
Année(s) de permis: 1993 1992 1990 1987
Résumé: As part of a long term study, I will continue to examine the biology of arctic and subarctic insects. Information will be collected on insect distributions as well as insect adaptations to living in environments with extremely cold winters and short summers. Studies on insect communities in the north may be good indicators of global climate change since they are short-lived species with limited a...


Genetics and postglacial dispersal of lake trout (Salvelinus namaycush) and arctic charr (S. alpinus) in the western arctic
chercheur principal:
Année(s) de permis: 1993 1992 1991 1990
Résumé: The researcher will be collecting lake trout and/or arctic charr from lakes in the vicinities of Hay River, Inuvik, Paulatuk and Tuktoyaktuk in order to examine the distributions of these species. Samples of liver and muscle tissue will be collected from these fish for genetic analyses: this research will provide information about how different populations are related to each other (i.e., their o...


Investigation of the nervous and immune systems in the beluga
chercheur principal:
Année(s) de permis: 1993
Résumé: This research will examine the nervous (i.e., brain) and immune systems of beluga by collecting these tissues from harvested animals for laboratory analyses. This study will help to determine how contaminants affect the health of belugas. In addition, the data collected may lead to a better understanding of why whales strand themselves on the shoreline as it has been suggested that beached whale...


Regional synchrony of lemming populations in the northern Yukon and Tuktoyaktuk region
chercheur principal:
Année(s) de permis: 1993 1992 1991
Résumé: The researchers will examine the cycles in lemming abundance (i.e., increases and decreases in the lemming population) for the western arctic region. Ongoing research suggests that lemmings in the Pearce Point area do not appear to reach very high numbers as has been noted in the eastern arctic and Scandinavia. Licence issued for use of Inuvik Research Centre....


Mitochondrial DNA Diversity in High-Arctic Populations of Daphnia pulex (water fleas)
chercheur principal:
Année(s) de permis: 1992
Résumé: The researcher and her team will collect Daphnia pulex (water flea) samples and maintain them in culture to obtain sufficient material for genetic analysis....
