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...

Summary: It is the objective of this project to collect information on the walleye population from the Horn River which can be used for managing the fishery and possibly changing the regulations. In order to reach this objective the following goals have been set out: 1. to collect population structure and spawning information by setting gill nets of varying mesh size and biologically sampling a portion of...

Summary: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of metals. Three types of sample collections are proposed. These would be done at selected sites along the Ingraham Trail (highway 4) east of Yellowknife. The...

Summary: The objective is to use Inconnu genetic samples to differentiate the inconnu populations residing in Great Slave Lake. If inconnu are philopatric (return to their natal spawning grounds) than each river should consist of a genetically distinct population. Methods include using gill nets to capture between 30 to 50 Inconnu per location (along Buffalo River, Buffalo Lake and Taltson River). Nets...

Summary: The purpose of this study is to directly measure temperature and dissolved oxygen concentrations in Airport Lake throughout the year, and to find out if low oxygen levels are limiting the growth rate of lake trout population in this lake. Repeated sampling at the same locations on the lake during fall, winter, spring, and summer will show whether oxygen levels are adequate for optimal lake trout t...

Summary: The objectives of our study are to 1) establish the importance of lake connectivity in determining the community composition and species richness of the invertebrate community of a lake, and the contribution of lakes of differing connectivity to the regional diversity of the Mackenzie Delta, 2) characterize the response of invertebrate communities to changing peak flood levels to allow prediction ...

Summary: This survey aims at discovering bioluminescent and biofluorescent species in Polar Regions (namely the Arctic), assessing and understanding the potential functions of the phenomena. Marcel Koken and his team hope to discover bioluminescent or biofluorescent species in the Arctic mesophotic zone. As the mission consists of an exploration of an under-studied part of the ocean, the scientific team...

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 ...

Summary: The objective is to describe the aquatic environment in the Yellowknife River between Bluefish Lake and Prosperous Lake as per the Fisheries Authorization and the Water Licence. This may include investigating aquatic vegetation, water quality and quantity, benthic invertebrates, fish and substrate. The results will be used to determine the most suitable means of fish habitat compensation or produc...

Summary: The objective of this project is to complete a Supplemental Baseline Monitoring Plan (SBMP) for water quality, fish population and benthic invertebrate programs. The SBMP contains two major study areas: Burke Lake, Reference Lake and the Marian River. Burke Lake will be the exposure area and Reference Lake will serve as the reference area for the SBMP. The exposure area for the Marian River wat...
