Reconstructing history of hummocky soil formation in drunken forest
Principal Investigator: Fujii, Kazumichi
Licensed Year(s): 2019 2018 2017
Summary: “Drunken forest” is developed on earth hummocks on shallow permafrost layer near Inuvik, Canada. Black spruce forests are typically grown on the shoulder of mounds and tree rings record the history of soil movement. By reading tree rings, The Principal Investigator (PI) is planning to reconstruct history of hummocky soil formation. The PI will collect tree core samples by making a hole in wood...

Photosynthetic Efficiency and Water Relations in Boreal Conifers under 24 Hour Environmental Light Conditions
Principal Investigator: Johnston-Schuetz, Cheryl
Licensed Year(s): 2007
Summary: The objective of this project is to examine the environmental thresholds to the successful establishment of a boreal (high latitude) conifer forest by measuring photosynthetic rates in conifer seedlings. Climate change has the potential to shift southern commercial tree species and treelines northward with implications for existing ecosystems and future economic development. The project’s goal ...

Environmental change in the 20th century, Mackenzie Delta region, Northwest Territories
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2008 2007 2006 2005
Summary: The impact of climate change on forest ecosystems in the Mackenzie Delta is being studied using dendrochronology. Earlier studies indicate a negative relationship between tree growth and summer temperatures. Summer temperatures may be exceeding the physiological threshold of northern trees or perhaps the trees are drought stressed. Manual and automatic dendrometers will be used to measure tree gro...

Autecology of Green Alder in the Mackenzie Delta
Principal Investigator: Lantz, Trevor C.
Licensed Year(s): 2006 2005 2004
Summary: The objective of this research is to explore the influence of temperature and disturbance on green alder by comparing alder characteristics on sites with different average temperatures and disturbance histories. Understanding of factors that influence alder populations today will assist in predicting the likely consequences of rising temperatures and increased disturbance on tall shrubs. A min...
