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...


Aquatic Environmental Effects Monitoring - Flat River at CanTung Mine
chercheur principal: Hoos, Rick
Année(s) de permis: 2012 2009 2002
Résumé: This work is being done to assist with the development of a future aquatic effects monitoring program for the mine that will meet the terms of the recently promulgated federal Metal Mining Effluent Regulations. The survey data will be provided in support...


Morphological Diversity in Lake Trout within Large North American Lakes: Effects of Lake Physiography on Differentiation between Deep and Shallow Forms
chercheur principal: Eschenroder, Randy
Année(s) de permis: 2002
Résumé: The immediate objective of the research is to determine whether unique morphotypes of lake trout exist in Great Slave Lake. The long term objective is to determine the distribution and ecology of unique morphotypes in North America. By studying Great Sla...


New ischnacanthid acanthodians from the Lower Devonian of the Mackenzie Mountains, NT, Canada
chercheur principal: Hermus, Chelsea
Année(s) de permis: 2002
Résumé: The main objective of the project is to collect fossils of two specific groups of early fishes (acanthodians and heterostracans) to supplement specimens already collected for research projects at the University of Alberta. The field party plans to journe...


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...


Desperation Pond and Carrie Pond Fish Transfer Program
chercheur principal: Armstrong, Allison
Année(s) de permis: 2001
Résumé: The capture and processing of fishes, including biological data collection, sample analysis, and recording of field data are the responsibility of BHP based on DFO approved methods described herein. The Project Biologist will be at site during crew training, to participate in the collection of data and to ensure the quality of data. The Project Biologist will also be responsible for collating an...


2001 Baseline Slimy Sculpin/Lake Trout Habitat Utilization Studies
chercheur principal: Madsen, Eric
Année(s) de permis: 2001 2000
Résumé: The objective of this study is two fold: a) to collect slimy sculpin tissue samples for baseline metal analysis; b) to monitor seasonal lake trout habitat utilization in Lac de Gras using radio telemetry methodologies. Twenty-five Slimy sculpins will be collected using baited minnow traps and opportunistic underwater netting, using professional SCUBA divers if available. Samples will be sent to ap...


Distribution of Dark-Celled Fungal Root Endophytes Along an Arctic to Boreal Latitudinal Gradient
chercheur principal: Piercey, Melissa
Année(s) de permis: 2000
Résumé: Roots of plants inhabiting cold-stressed environments are often colonized by vegetatively reproducing fungi. The researcher will examine the genetic variation within and among populations of Phialocephala fortinii P. along a latitudinal gradient encompassing the boreal, subarctic and arctic zones in Northern Canada. The researcher will travel from Yellowknife to 3 study sites surrounding Great ...


Trilobite biostratigraphy of Rockslide Formation (Middle Cambrian)
chercheur principal: Pratt, Brian R.
Année(s) de permis: 2012 2002 2000 1998
Résumé: Outcrops in the Mackenzie Mountains preserve an almost uninterrupted sequence of strata of Cambrian age. This study aims to collect in bed-by-bed detail the trilobite fossils from the Rockslide Formation, the Middle Cambrian portion of the sequence. The taxonomy and biostratigraphy of these fossils will generate a refined time scale for this part of the geologic column, some half a billion years o...


Genetic Diversity in the Biota of Arctic Lakes
chercheur principal: Hebert, Paul
Année(s) de permis: 1997
Résumé: 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...
