Morphological Diversity in Lake Trout within Large North American Lakes: Effects of Lake Physiography on Differentiation between Deep and Shallow Forms
Principal Investigator: Eschenroder, Randy
Licenced Year(s): 2002
Summary: 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...


Paleohydrological and Paleoecological Reconstruction of the Mackenzie Basin Deltas
Principal Investigator: Wolfe, Brent BBW
Licenced Year(s): 2007 2006 2005 2004 2003 2002
Summary: This project will formulate a comprehensive history of the frequency and magnitude of floods and droughts and corresponding ecological responses in the Mackenzie Basin deltas over the past 1000 years. Results from this study will provide an essential dat...


1999 Aquatic Baseline Studies Program.
Principal Investigator: Tyson, J. David
Licenced Year(s): 1999
Summary: The objectives of this project are to: 1. determine the presence of fishes in selected waterbodies on the BHP Diamonds claim block, 2. determine the extent of utilization of streams by fishes as migration routes, and 3. inventory the quantity and quality of fish habitat in waterbodies supporting fishes. The potential species involved in this monitoring program are Arctic grayling, burbot, lake tr...


Ecological and geomorphological investigations in the alpine tundra of the Mackenzie Mountains, NWT.
Principal Investigator: Kershaw, G. Peter
Licenced Year(s): 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: The main study objectives are to: 1) determine the status of permafrost landforms in the study area, and 2) determine long-term recovery after abandonment of the CANOL No. 1 project. Access during the summer is via the Yukon along the Canol Road through Macmillan Pass. Beyond the base camp mountain bikes and foot will be the means of transport. Automated microclimate stations powered by solar ene...


Geomorphologic analysis of the Mackenzie Delta, N.W.T. using spatial image processing.
Principal Investigator: Boyes, Donald M.
Licenced Year(s): 1995 1994 1990
Summary: The collection of the field data is required to calibrate satellite image clasifications and interpretations concerning water body measurements, plant community types, and sedimentation patterns. Field measurements will include measuring ground distances and recording plant characteristics. Nothing in the field area will be destroyed or removed....


Grizzly and Black Bear Habitat Use Study and Bear Hazard Assessment of the Rabbitkettle Lake Area of Nahanni National Park Reserve.
Principal Investigator: Ashton, Sandra
Licenced Year(s): 1995 1994
Summary: Data collection for food habits analysis will involve collection and analysis of bear scats and will be supplemented by direct observation of bears in the field. Where feeding or other sign (e.g., mark tree, digging, tracks) site investigations will be carried carried out involving recording inventory, cover value and phenology of all potential bear foods present and taking measurements pertinent...


Investigation of Distribution and Range Boundaries for Some Common Subarctic Inscects Occuring at or Near Treeline
Principal Investigator: Royer, Ronald A.
Licenced Year(s): 1995
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...


Paleontology & Sedimentology of Late Proterozoic Reefs, Mackenzie Mountains, NWT.
Principal Investigator: Narbonne, Guy
Licenced Year(s): 2001 1999 1998 1996 1994 1992 1991 1989 1988
Summary: Field work will involve detailed measurement & description of stratigraphic sections using a range pole and compass, and mapping and selective sampling of reefs using a geological hammer. Follow-up work at Queen's University will involve analysis of field data and examination of samples using a variety of laboratory techniques. These reefs are an ecological "missing link" between the two major re...


Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licenced Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: Researchers will evaluate the spatial variability of nutrient chemistry during the snowmelt period within the drainage network of the tundra stream ecosystem. Evaluation of the controls on nutrient chemistry and community metabolism in streams withing the borel forest/tundra ecotone through the measurement of algae and organic matter in the stream. Evaluation of the potential role of Mackenzie De...


Northern River Basins Study Traditional Knowledge Documentation Project
Principal Investigator: Bill, Lea
Licenced Year(s): 1994
Summary: The primary focus of this study will be on the older population (65 years and older). Data on traditional knowledge will be collected by interviews, survey questionnaire, and audio and video taping. Information gathered will be used to document the history of traditional ecological knowledge and to demonstrate the value of traditional ecological knowledge in scientific research and in predictions ...
