Principal Investigator: Tennent, John
Licensed Year(s): 2002
Summary: This is the first part of a planned review of the circumpolar butterfly genus Erebia. The researcher will be self driven. Photographs will be taken of live Erebia specimens and habitats. Voucher specimens will be collected using standard insect net, for...

Summary: 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...

Summary: 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...

Principal Investigator: Wilson, Chris C.

Summary: 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...

Principal Investigator: Chiperzak, Doug
Licensed Year(s): 1992
Summary: The researchers will conduct a mobile hydroacoustic survey from a 20 ft. boat using a BioSonics dual-beam echo-sounder and recording system. A limited amount of gillnetting will be conducted to provide groundtruthing information for the acoustic data. Target strength analysis will also be conducted....

Principal Investigator: Nicholson, Barbara
Licensed Year(s): 1992
Summary: The Researcher will map the present distribution of boreal and subarctic wetlands in the Mackenzie River Basin. Wetland vegetation and water chemistry will be described for areas immediately surrounding permanent weather stations. The ecological relationships between climate, wetland water chemistry and wetland species distribution will be analyzed. A predictive indicator model will be built to pr...

Principal Investigator: Behan-Pelletier, Valerie
Licensed Year(s): 1987
Summary: To study and collect insects and mites along the Dempster Highway from the Yukon border to Inuvik and in the northern Richardson Mountains west of Inuvik....

Principal Investigator: Garry, Clarke E.
Licensed Year(s): 1988 1987
Summary: To determine the beetle species that are found in specific biogeographical zones, what species are likely to be found together in specific locations, and what the habitat preferences of the collected species are....

Principal Investigator: Norton, Pamela
Licensed Year(s): 1985
Summary: To monitor the white whale migration to and distribution and abundance in the Mackenzie Estuary. Secondary objectives are to observe white whale behaviour, to record whale-vessel interactions (if possible) and to quantify the number of whales missed by observers under normal survey conditions. All marine mammal sightings will be recorded....

Principal Investigator: Courtney, Gregory W.
Licensed Year(s): 1984
Summary: To determine what species of mountain midges (aquatic flies) inhabit the Richardson Mountains; describe any new species; determine the phylogentic and zoogeographic relationships of these species....
