Carbon Capture by Boreal Afforestation: feasibility for Canada's net-zero emission goals
Principal Investigator: Whyte, Lyle
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 6013. The overall goal of this project is to provide a comprehensive evaluation of carbon capture capacity of the northern tree line migration into the northern regions of Canada. Specifically, the research group's objective is to identify if soil and plant root associated microbial communities inhabiting areas very close ...

Ecology of white spruce at the species limit in NWT, Canada
Principal Investigator: Walker, Xanthe J
Licensed Year(s): 2009 2008
Summary: The overall objective of this research is to determine the impact of climate change on the ecological patterns and processes of white spruce trees within the forest-tundra transition zone in the Tuktoyaktuk region of the Northwest Territories, Canada. White spruce reproduction, establishment, and growth will be assessed to determine how these parameters may have changed since they were last measur...

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...

Environmental Studies Across Treeline, Mackenzie Delta Region
Principal Investigator: Kokelj, Steven V
Licensed Year(s): 2012 2011 2010 2009 2008 2007 2006 2005
Summary: There are three main parts in the researchers' project: 1) investigating the relationships between air and ground temperatures across treeline; 2) investigating the effects of permafrost degradation on the water quality of tundra lakes; and 3) examining...

2000 Years of Climate Change at Treeline North of Yellowknife
Principal Investigator: MacDonald, Glen M
Licensed Year(s): 2005
Summary: The researchers believe that the treeline zone is one of the most sensitive areas on earth to temperature changes, both natural and caused by global warming. They would like to take a small core (5 cm diameter) from the mud at the bottom of two small lakes close to Back Lake, northeast of Yellowknife. In the laboratory, they will analyze the cores for temperature-sensitive aquatic insect remains...
