Principal Investigator: Boa-Antwi, Kofi
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.5016. The goal of this project is to determine whether dust generated from mining activities is causing a measurable change in dust deposition to and/or metals uptake in lichen closer to and further from the mine. If a significant difference in uptake is noted closer to versus further from the mine, a health risk assessment...

Principal Investigator: Doubt, Jennifer
Licensed Year(s): 2018
Summary: The objective is to increase knowledge of bryophytes (e.g., mosses, liverworts) and (incidentally, where possible) lichens in the Northwest Territories. Waterfall areas can offer a wide diversity of microhabitats (featuring a large variety of substrates, moisture and light levels, and exposures) within a relatively small area. Bryophyte species and communities are often associated with specific...

Principal Investigator: Katz, Sharon
Licensed Year(s): 2007
Summary: The monitoring objectives of this project are: to conduct a targeted scientific program to analyze heavy metals and trace elements and stable isotopes in vegetation (caribou food); to correlate the results in vegetation with concentrations in caribou from a related NCP program [Gamberg 2006]; to test if contaminant patterns in caribou tissues will vary with patterns observed in lichen/moss, or wil...

Principal Investigator: Robinson, Cindy
Licensed Year(s): 2004
Summary: This fieldwork is for reclamation planning at the Tundra Mine site. An aquatic survey will be conducted to characterize the current conditions of water bodies adjacent to the Tundra Mine and downstream of the mine's two tailings ponds. A total of seven l...

Licensed Year(s): 1994 1993 1992 1991 1990
Summary: Project 1: Small samples of lichens will be collected from approximately 20 sites located along the Hood River and analyzed for contaminants. Lichens are good indicators of the types of air-borne contaminants that have been carried north to the arctic since they absorb their nutrients from the air. Project 2: The researcher will examine plant communities along the Hood River in order to study th...

Principal Investigator: Aspler, L.B.
Licensed Year(s): 1993 1992
Summary: A field crew of four people will map (by foot and boat) the rocks deposited in ancient (2,500 to 1,900 million year old) basins. These rocks will also be assessed for their economic potential. The field work will also involve the collection of water, moss and lichen to determine levels of contaminants as part of the northern contaminants study funded by the Arctic Environmental Strategy....

Principal Investigator: Fahselt, D.
Licensed Year(s): 1992 1991 1990
Summary: The Researcher will compare the levels of enzyme variation from populations of umbilicate species from the Arctic as well as from the southern limit of their ranges in southeastern USA. The objective will be to ascertain whether there is any correlation between the level of variability in enzyme patterns and latitude....

Principal Investigator: Svoboda, Josef
Licensed Year(s): 1994 1993 1992 1991 1988 1987
Summary: To study plant communities and conduct vegetation mapping; to study primary producers - herbivore (muskox) interactions (impact of grazing on vegetation); to document lichen diversity and growth; to document the history and age of the vegetation at Sverdrup Pass....

Principal Investigator: Svoboda, Josef
Licensed Year(s): 1985
Summary: To study productivity of high Arctic meadows; continue measurements of the Alexandra Fiord glacier; to remeasure marked colonies of saxicolous lichens....

Principal Investigator: Brassard, Guy R.
Licensed Year(s): 1980
Summary: To collect specimens and study the habitat of mosses and lichen in the field....
