2011 Summary:
The primary objective of this project is to collect B. chariclea arctica from sites in the Yukon and Northwest Territories. A network of haplotypes will be constructed, based on the mitochondrial cytochrome c oxidase subunit I (COI) gene, and a mismatch analysis will be performed to determine if genetic structure has been influenced by a sudden expansion in population size or long term stability. ...

Summary:
The research plan is to collect specimens of as many species (named or not) of the wasp subfamily Microgastrinae (Hymenoptera: Braconidae) to get recent and properly preserved specimens for DNA barcoding and taxonomic resolution. The goal is to know more about the diversity of these wasps and to be able to compare the recently wasp fauna with re-identified specimens sampled in the 1950’s.

Summary:
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...

2000 Summary:
The primary focus of the study is the numbers and kinds of insects that live in the Thelon River at its valley. A previous study in 2000 on the Horton River revealed a number of species that are not represented in Alaska and the Yukon. Collections from t...

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...

1992 Summary:
The sample of arctic-alpine ground-beetles will be collected under rocks and by pitfall traps (dixie cups placed in 8 cm diameter drilled holes) in the tundra habitat. All rocks will be replaced exactly and pitfall trap holes refilled with their soil plugs. No chemicals will be used in any of the trapping or collecting. Specimens will be analysed using DNA techniques which include RLPF's and PC...

Summary:
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...

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...

199219901987 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...

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...
