Hybridization and genetic variation in arctic grasses: molecular, morphological and ecological evidence.
chercheur principal: Gillespie, Lynn J.
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...


Distribution, systematics and genetic structure of western arctic zooplankton species
chercheur principal: Hebert, Paul D.N.
Année(s) de permis: 1993
Résumé: Zooplankton will be collected from lakes and ponds located along a transect between Paulatuk and Shingle Point (Yukon). The specimens that are collected will be identified according to species type and genetic analyses will be performed to determine what species are interbreeding to produce hybrid organisms. Knowledge about zooplankton is important as many organisms (such as fish) depend on thes...


Genetic Diversity and Hybridization Among Sympatric Populations of Arctic Char and Lake Trout
chercheur principal: Wilson, Chris C.
Année(s) de permis: 1993 1992 1991 1990
Résumé: The Researchers will continue to examine genetic diversity and hybridization between lake trout and Arctic char. They will gather data on the hybrid's ecological role. Different areas will be sampled to determine where the parent species and hybrids occur....
