Contemporary Dynamics of Forest-Tundra Ecotones in Central NWT
Principal Investigator: Danby, Ryan K
Licenced Year(s): 2016
Summary: Objectives of this research project are to: 1) analyze Landsat satellite images to understand regional vegetation change over the past 30 years; 2) determine the timing of tree establishment as well as the climate influence on tree growth across the forest tundra transition zone over the past 300 years; and, 3. measure spruce seedling growth across the forest-tundra ecotone in relation to varia...

Quantifying carbon fluxes and budgets of boreal forest-tundra landscapes under the influence of rapidly changing permafrost regimes
Principal Investigator: Sonnentag, Oliver
Licenced Year(s): 2016 2015 2014 2013
Summary: The objectives of this research project are to: 1) determine if the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the discontinuous and continuous permafrost zones; 3) determine if the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale...

Soil Carbon in the Mackenzie Delta Region
Principal Investigator: Phillips, Marcus R
Licenced Year(s): 2015 2014 2013
Summary: The goal of this research is to understand how landscape processes influence the quantity and quality of soil carbon in the Mackenzie Delta Region. Particular attention will be paid to the depth distribution of soil carbon and how it is affected by differences in vegetation and soil forming processes. Key environmental differences that will be examined include forest vs. tundra and delta vs. uplan...

Carbon dynamics in chronosequence of boreal forest ecosystems: a production ecological approach
Principal Investigator: Osawa, Akira
Licenced Year(s): 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001
Summary: Northern forests are closely connected to the issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The main objectives of the 2005 field season are to collect data on the annual growth of fine roots, and to further examine the rate of soil respiration. Both of these...

Social-Ecological Indicators for Community Based Monitoring and Resource Management
Principal Investigator: Parlee, Brenda L
Licenced Year(s): 2004 2003
Summary: This project involves working with the Gwich'in Renewable Resources Board, the Tetlit Gwich'in Renewable Resources Committee and elders/harvesters from Fort McPherson to document traditional indicators and methods for community-based monitoring. The main...

An Exploratory Evaluation of the Effect of the Climate Change During the Past Two Centuries on Structure of Jack Pine Forests.
Principal Investigator: Osawa, Akira
Licenced Year(s): 1999
Summary: The main objective of the proposed research is to reconstruct the structure of monospecific forests of different ages, and to explore whether or not the recent climate change has affected the structure of the forests in northern Canada. Pure stands of Jack pine or aspen will be studied in Wood Buffalo National Park. The intent is to determine the effect of the so-called Climate Change on those f...

Licence #1963
Principal Investigator: Rouse, W.
Licenced Year(s): 1976
Summary: To develop a classification of fire effects on the microclimate of forest and tundra ecosystems....
