A phylogenetic and phylogeographic study of predaceous diving beetles in the Nearctic with a focus on the tribe Agabini (Coleoptera, Dytiscidae, Colymbetinae).
Principal Investigator: Venables, Chandra
Licenced Year(s): 2011
Summary: The objectives of this research project are to: 1) establish evolutionary relationships of diving beetles in the Nearctic, in addition to identifying colonization routes for exemplars in the tribe Agabini; 2) assess genetic diversity of target species and among-population genetic mixing, and compare these data to historical data (where possible) with an aim at assessing latitudinal and historica...


2000 Years of Climate Change at Treeline North of Yellowknife
Principal Investigator: MacDonald, Glen M
Licenced Year(s): 2005
Summary: The researchers believe that the treeline zone is one of the most sensitive areas on earth to temperature changes, both natural and caused by global warming. They would like to take a small core (5 cm diameter) from the mud at the bottom of two small lakes close to Back Lake, northeast of Yellowknife. In the laboratory, they will analyze the cores for temperature-sensitive aquatic insect remains...


Insect Biodiversity and Biogeography along the Horton River, NWT
Principal Investigator: Currie, Douglas C.
Licenced Year(s): 2002 2000
Summary: This study will be a comprehensive collecting programme that will provide baseline information about aquatic-insect composition along the Horton River. The survey will also provide baseline information about aquatic insect composition, which may be used to monitor changes in water quality over time. The survey will last 3 1/2 weeks as the research team travels by canoe along the Horton River. T...


Resource Utilization and Competition Among High Arctic Hydroporus Species (Coleoptera: Dytiscidae)
Principal Investigator: DeBruyn, Adrian
Licenced 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....


BORUP FIORD 91
Principal Investigator: Hankinson, Flt. LT. K.W.
Licenced Year(s): 1991 1988
Summary: Multi-disciplinary research will be undertaken in botany, geology, micro meteorology, soil science, remote sensing, breeding biology of Arctic char and archaeological survey. These studies are a continuation of those begun in 1988....


Licence #4076
Principal Investigator: Courtney, Gregory W.
Licenced Year(s): 1984

Licence #2654
Principal Investigator: Barr, David W.
Licenced Year(s): 1981
Summary: To make a detailed study of aquatic mite and benthic invertebrates (small aquatic organisms) in the lakes, ponds and streams. Samples of all types will be collected for preservation in the museum's research collection....
