Canadian Global Change Transect: Northern Transect
chercheur principal: Kerr, Jeremy T
Année(s) de permis: 2012
Résumé: The Canadian Global Change Transect (CGCT) is a project of the Canadian Facility for Ecoinformatics Research at the University of Ottawa. The goal of the project is to assess and predict the effects of historical and future global changes on the spatial distribution of Canadian butterfly species through time. One of the key aspects of the CGCT to develop historical range calibrated models is the c...


Butterfly Inventory in the NWT
chercheur principal: Layberry, Ross
Année(s) de permis: 2005
Résumé: Butterflies are easily studied and can provide valuable information of changes occuring in northern ecosystems - including climate changes, and habitat changes. Many areas of the NWT have few studies on insects; therefore, this inventory work can inprove the baseline information of these species. The main investigator will travel with other NWT biologists to remote study sites and near comm...


A Review of the Butterfly Genus Erebia
chercheur principal: Tennent, John
Année(s) de permis: 2002
Résumé: 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...


Investigation of Distribution and Range Boundaries for Some Common Subarctic Inscects Occuring at or Near Treeline
chercheur principal: Royer, Ronald A.
Année(s) de permis: 1995
Résumé: The researcher will investigate range boundaries and species intergrade zones. The researcher will also possibly define ecological limiting factors for selected apecies of common arctic insects, principally in the order of Lepidoptera. This data will fill numerous gaps in understanding of distribution and speciation for the targeted species, the ranges of many of which are assumed but not yet co...


Biology, ecology and cold tolerance of arctic insects
chercheur principal: Ring, Richard A.
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...


Fossil and Modern Coleopteran Ecology in Arctic Canada
chercheur principal: Morgan, Alan
Année(s) de permis: 1991
Résumé: 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....


Insects and arachnids in the northern Richardson Mountains of the Yukon and NWT and the Dempster Highway.
chercheur principal: Behan-Pelletier, Valerie
Année(s) de permis: 1987
Résumé: 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....


Ecology of beetles, especially ground beetles, of boreal forest, open woodland, and tundra of the Yukon Territory and Northwest Territories.
chercheur principal: Garry, Clarke E.
Année(s) de permis: 1988 1987
Résumé: 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....


Licence #2214
chercheur principal: Ball, G.E.
Année(s) de permis: 1977
Résumé: To study the distribution of cryobius (species of beetle) as a potential indicator of past climates....
