Diavik Fish Palatability & Metals Program
Principal Investigator: English, Colleen J
Licensed Year(s): 2012 2009 2003
Summary: The purpose of the study is to have Aboriginal participation in monitoring programs at the Diavik site; to assess the quality of fish for eating – records of fish taste, smell and texture from fish caught in Lac de Gras; collection of fish tissue samples to analyze for metals concentrations; collection of fish otoliths to determine age of fish; focus on sampling fish of similar size/age in order t...


Miramar Con Mine Environmental Effects Monitoring (EEM) Phase 3 Study – Investigation of Cause
Principal Investigator: Machtans, Hilary
Licensed Year(s): 2018 2015 2012 2009 2007
Summary: The EEM will investigate the cause of differences in fish health that were observed in fish from an area exposed to mine effluent (Jackfish Bay) when compared to fish not exposed to mine effluent (Horseshoe Island Bay). Data will be examined to see what environmental factors are causing the observed effects. Fish Program: A small-bodied fish survey will be conducted within one exposure ar...


Bioaccumulation of Brominated Flame Retardants, Currently Used Pesticides, and emerging metal trends in the Vegetation-Caribou-Wolf Food Chain
Principal Investigator: Katz, Sharon
Licensed Year(s): 2009
Summary: The objectives of this study are: (a) To determine whether brominated flame retardants (BFRs), current use pesticides (CUPs), perfluorinated compounds (PFCs), and mercury bioaccumulate using the vegetation-caribou-wolf food chain and the Bathurst caribou herd as a model; (b) To explore possible sources of lead contamination in the Bathurst herd caribou; (c) To elucidate the pathway of lead uptake ...


Quantifying the effects of mining activities on the health of streams in the South Nahanni Watershed (NWT)
Principal Investigator: Scrimgeour, Garry J
Licensed Year(s): 2009 2008 2007
Summary: The researchers propose to address critical information gaps by embarking on a research project in the South Nahanni River Watershed. The objectives of the research are: 1) To quantify natural variability of benthic macroinvertebrate communities at reference sites un-impacted by human activity; 2) To determine whether mining activities degrade the health of streams in the South Nahanni Watershed...


Botanical collecting - Dempster Highway and Mackenzie Delta
Principal Investigator: Darnell, David M.
Licensed Year(s): 2009
Summary: This licence is being issued for the scientific research application No.1095. The objective of this research is to obtain specimens of the major plant species comprising the plant communities found in the northwestern Northwest Territories, especially those riparian ones not found in the adjacent Yukon Territory. The researchers will employ standard botanical field techniques and equipment...


Dezé Energy Corporation Ltd. Taltson Expansion Project
Principal Investigator: Azzolini, Louie
Licensed Year(s): 2009 2008
Summary: This licence is being issued for the scientific research application No. 1124. This is a three part study with separate objectives for each. The objectives are as follows: 1) The Fish Study: Evaluate the impacts associated with four locations requiring in-stream works; quantify and qualify fish habitat values at each of the four locations; identify potential locations to improve existing fish...


Changing fire regimes in northern coniferous forests
Principal Investigator: Wallenius, Tuomo H
Licensed Year(s): 2009
Summary: This licence is being issued for the scientific research application No.1103. The research objective is to study the occurrence of forest fires in Northern Canada during the past 200 years. They are especially interested in large scale averages and changes in the estimated fire return intervals/annually burned proportions of the landscape. Specific research questions are: 1. How often for...


Treeline Dynamics in Western Canadian Arctic
Principal Investigator: Green, Scott
Licensed Year(s): 2009 2008
Summary: The project will examine past tree growth patterns at the northern treeline in Western Canada as a baseline to predict future growth responses to climate change. Additionally, the researchers will examine tree regeneration and plant associations at the northern treeline. Annual tree rings represent a growth response to local climate. Wide growth rings represent good growing conditions, and nar...


Black Spruce Fertility at the Arctic Treeline
Principal Investigator: Greene, David F
Licensed Year(s): 2009
Summary: The research objective is to show that the fertility of black spruce (Picea mariana) in the Arctic is limited by the amount of pollen in the surrounding air. After snowmelt, the researchers will choose unburned black spruce “islands” at different distances from the perimeter of the 1999 Lynx Creek fire. Subsequently, as the developing black spruce pollen cones become easy to see, they will remo...


Conceptual and Mechanistic Models for the Development and Survival of the Trichostrongylid, Ostertagia gruehneri, in Barrenground Caribou, With Respect to Northern Climate Change
Principal Investigator: Hoar, Bryanne M
Licensed Year(s): 2009 2008 2007
Summary: The objective of this study in 2009 is to determine if parasites (Ostertagia gruehneri) can survive on the tundra over winter. This is the third year of a three year study. This work is to study the parasite Ostertagia gruehneri. This is the most common stomach worm in barrenground caribou. Adult worms live in the stomach of caribou and eggs are shed in the feces of the caribou. Once in the env...
