Temperature relations and interactions of arctic woolly-bear caterpillars and their insect parasitoids
Principal Investigator: Morewood, Dean
Licensed Year(s): 1994 1993
Summary: Surveys will be conducted in order to: (1) document the life stages of the caterpillars (e.g., eggs, larvae, pupae and adults) during the summer; (2) count the number of caterpillars killed by insect `parasites' or parasitoids; and (3) document the timing of the insect parasitoids's life cycle. Finally, since temperature affects growth, experiments with different temperatures will be use to exami...


Biology, ecology and cold tolerance of arctic insects
Principal Investigator: Ring, Richard A.
Licensed Year(s): 1993 1992 1990 1987
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...


Mosquito Baseline Study for the City of Yellowknife
Principal Investigator: Ellis, R.A.
Licensed Year(s): 1993
Summary: The mosquito baseline study is aimed at determining which mosquito species breed in and around Yellowknife. While sampling for mosquito larvae, samples of non-target (i.e., other) insect species will also be taken to determine which of these species are natural predators or parasites of mosquitoes, or should be protected for other reasons. The City of Yellowknife will be provided with recommenda...


Electrophoretic Studies of North American Halictid Bees
Principal Investigator: Taylor, John S.
Licensed Year(s): 1992
Summary: The researcher and his team will collect specimens of bees that belong to the subgenus Evylaeus (Family Halictid), which are small "ant-like" bees sometimes called "sweat bees." The researcher would like to determine how they are related to the European species, which, unlike the Evylaeus, are social in their behaviour. This study may shed some light on the evolution of social behaviour in bees....


Resource Utilization and Competition Among High Arctic Hydroporus Species (Coleoptera: Dytiscidae)
Principal Investigator: DeBruyn, Adrian
Licensed Year(s): 1992 1991
Summary: Hydroporus morio and H. Polaris (two species of small aquatic beetles) coexist as major predators in a series of shallow temporary ponds at Alexandra Fiord. This study will investigate the biology of predaceous insects in freshwater habitats in the high arctic....


Mechanisms Mediating Freezing Tolerance in Arctic Insects
Principal Investigator: Kukal, Olga
Licensed Year(s): 1992 1991
Summary: The research team will continue to study the ecophysiology of of arctic insects....


Fossil and Modern Coleopteran Ecology in Arctic Canada
Principal Investigator: Morgan, Alan
Licensed Year(s): 1991
Summary: The Researchers will collect sediment samples. Insect fossils will be extracted and analysed. The insect communities recovered will provide an indication of the climatic conditions in the area at the time the sediments were deposited. The age of the sediments will be determined with radiocarbon or other dating methods....


Early Quaternary and Late Tertiary Geology and Geomorphology, Arctic Islands
Principal Investigator: Fyles, John G.
Licensed Year(s): 1992 1991 1990
Summary: On Melville and Bathurst Islands, the Researchers will locate and describe the occurrence of high-level gravels and sands, record evidence of the flow-direction of the rivers in which they originated and search for plant and insect fossils that may provide clues about the age of these deposits and about the climate and environment at that time....


Inter-relationships Between Internally Feeding Insects and Species "Pedicularis" in the High Arctic
Principal Investigator: Meier, Sharon
Licensed Year(s): 1991 1990
Summary: The Researcher will continue to study plant-insect relationships and factors which play determining roles in the lives of organisms inhabiting the Arctic environment....


Ecologie de la Reproduction des Plants Turbicoles et Arctic
Principal Investigator: Comtois, Paul
Licensed Year(s): 1991
Summary: The Researcher will study the behavior of pollinating insects (bees) in ecosystems dominated by plants of the blueberry family (Ericacees). They will investigate competition between flowering plants syncronized for the same insect pollinators. Most of their work will be conducted on Herschel Island. Minimal study will be conducted near Tuktoyaktuk near their base camp at Polar Continental Shelf Pr...
