A Coastal, Pan-Canadian Collection of Plants, Microalgae, and Marine Invertebrates for the Canadian Museum of Nature
Principal Investigator: Graham, Mark S
Licenced Year(s): 2017
Summary: The goal of this work is to assemble a representative collection of marine invertebrates, vascular plants, lichens, mosses, liverworts and aquatic, microscopic algae for research and educational purposes at the national museum (the Canadian Museum of Nature). Specimens will be used in ongoing research projects at the Canadian Museum of Nature, focused on the biodiversity of the vascular plant, lic...


Drivers of lichen diversity at different latitudes
Principal Investigator: Scharnagl, Klara
Licenced Year(s): 2017
Summary: The objectives at Scotty Creek in the Northwest Territories of Canada is to get a high latitudinal point for the field sampling study. Many latitudinal gradient studies overlook the boreal and tundra ecosystems, yet they are host to a rich lichen flora. The Principal Investigator (PI) will survey lichen diversity at Scotty Creek, contributing to local knowledge in addition to the understanding of ...


Reclamation of Disturbed Sites Research at Diavik Diamond Mine, NWT
Principal Investigator: Naeth, M. Anne
Licenced Year(s): 2017 2016 2015 2014 2009 2008 2005
Summary: The overall research goal is to determine appropriate methods to restore disturbed sites at Diavik Diamond Mine to productive and sustainable tundra communities following mine closure. There are three main research areas 1) building suitable reclamation substrates for plant establishment and growth, 2) methods of collection and propagation of locally common native plant and lichen species, and 3) ...


Lichen Sampling Program - Diavik 2013
Principal Investigator: Wells, David A
Licenced Year(s): 2013 2010 2005
Summary: The aim of this research 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 to caribou may be conducted to determine risks associated with consumpti...


Environmental Studies for the Proposed Parsons Lake Development Area During Summer 2007 – Vegetation Studies
Principal Investigator: Graf, Linda H
Licenced Year(s): 2007 2006
Summary: The objective of the vegetation study is to continue to record baseline information on lichen health and productivity which may then be used to monitor impacts as a result of construction and operation activities in the proposed Parsons Lake development area. These studies are a continuation of those conducted previously in summer and fall of 2006. The study will link to caribou monito...


Metals Uptake from Vegetation to Caribou in the Canadian Arctic
Principal Investigator: Katz, Sharon
Licenced 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...


Glaciological Investigations in the Ragged Range
Principal Investigator: McCarthy, Daniel P
Licenced Year(s): 2006 2005
Summary: The objectives of this study are to: 1) inventory the size and morphometry of glaciers in the Ragged Range; 2) find and document geological and botanical evidence of former glacier activity; 3) develop a chronology for Holocene glacier activity in the Ragged Range; and, 4) develop one or more growth curves for lichens growing on carbonate and/or silicate rocks. Also, the field reconnaissance and b...


Environmental Investigations for Reclamation Planning at the Tundra Mine
Principal Investigator: Robinson, Cindy
Licenced 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...


Phylogenetics of Omphalina (Basidiomycotina, Agaricales) and the evolution of lichenization
Principal Investigator: Lutzoni, Francois
Licenced Year(s): 1993 1992
Summary: I will be collecting lichens in the vicinity of Iqaluit in order to better understand the variety of species that grow in the high arctic. Some species of fungi grow with algae: these partnerships are recognized as lichens. In an attempt to study this partnership, I will separate the fungi part from the algae and grow each separately in a laboratory. I will also be visiting Greenland and Icelan...


Lichens as indicators of trace-element air pollution in the environment and environmental controls on plant species richness and composition along an arctic river
Principal Investigator: Gould, William
Licenced 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...
