Summary: Through this project the research team will address the following objectives: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the discontinuous and continuous permafrost zones? Is the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale ...

Summary: The ultimate aim of the proposed project is to develop and evaluate a detailed process-based model of vegetation-soil-permafrost interactions using data collected through directed field campaigns in the discontinuous and sporadic permafrost zones of western Canada. The research team will (i) elucidate the role of plant biodiversity in controlling permafrost status in contrasting ecosystems with di...

Summary: The objectives of this research is to: determine total arsenic and arsenic species in edible and non-edible mushrooms from contaminated and uncontaminated locations (mine properties and roadsides/parks); determine total arsenic and arsenic species in plants including Labrador tea, horsetails, buffaloberry, fireweed and berries (if available) from contaminated and uncontaminated locations (mine pro...

Summary: This project is to fill gaps in ecological information on a Candidate Protected Area while it makes its way through the NWT Protected Areas Strategy (PAS) process. This information will be used by the working group to make recommendations on final boundary and management planning for the area. The study will be done at the same time as a study on mercury in fish being conducted by the Dehcho F...

Summary: The objective is to quantify the amount of fuel combustion and carbon losses during wildfires in boreal conifer forests and peatlands. These data will allow us to quantify climatic and weather controls on the severity of biomass burning. Boreal forests and peatlands store a large amount of carbon in vegetation and soils. Climate change is predicted to increase summer drought, which could mak...

Summary: The objective of this study is to continue with phytoremediation planting on the Nota Creek C-17 well site. Additional plantings are necessary to determine the efficiency of the phytoremediation program and to further assess its viability as a remediation strategy for the well site. A backhoe will be mobilized to the site under frozen ground conditions. A portion of or all of the impacted soil ...

Summary: The Research long term goals are to: 1) produce the first “Flora of the Canadian Arctic”, a field guide to all plant species of the Canadian arctic; 2) implement an Arctic Plant website to provide easy access to information; 3) undertake studies on diversity and distribution of arctic plants and mosses; and 4) obtain DNA barcodes for all Canadian Arctic plants. The objectives on Victoria Island in...

Summary: Main objective of the 2009 fieldwork is to collect data in jack pine and black spruce forests on annual movement of organic matter and carbon. For this purpose, the researchers will continue measurement of the growth of fine roots and amount of aboveground litter. Additional objective is to establish a several-square-kilometer study area of mostly black spruce for a regional study of stand devel...

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 ...

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...
