Principal Investigator: Nielsen, Jennifer L.
Licensed Year(s): 2008 2007
Summary: This study aims to: 1) use genetics and otolith (ear bone) microchemistry to determine if differences exist between collections of Arctic cisco (herring) made from tributaries of the Mackenzie River (Canada) and the Colville River (Alaska) and 2) use differences to identify population-of-origin of fish caught in the Colville River subsistence fishery. Approximately 60 Arctic cisco will be colle...

Principal Investigator: Millar, Nathan P
Licensed Year(s): 2006
Summary: This study involves the determination of the population structure of fish in the Mackenzie River. Specific objectives include the delineation of stocks of three fish species: loche (Lota lota), crookedback (Coregonus clupeaformis) and coney (Stenodus leucicthys), and the identification of downstream fisheries as mixed-stock or single-stock fisheries. A population genetics approach will be employed...

Summary: The objectives of this research are: 1) to gather baseline data on size, age structure, fecundity (egg number per female), growth and mortality for lake trout in the study area; 2) to determine if lake trout are genetically distinct between basins of Great Bear Lake; and, 3) to determine the extent of movements by lake trout in Great Bear Lake by using molecular genetics. Field crews will be tr...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2005
Summary: This study is designed to investigate various measures of small fish health at a number of locations along the Mackenzie River. The researchers want to find out if small fish health is different near oil seepages and the islands at Norman Wells than in other parts of the river. Also, the researchers will investigate fish and benthic invertebrate abundance and species composition at selected strea...

Summary: Butterflies are easily studied and can provide valuable information of changes occuring in northern ecosystems - including climate changes, and habitat changes. Many areas of the NWT have few studies on insects; therefore, this inventory work can inprove the baseline information of these species. The main investigator will travel with other NWT biologists to remote study sites and near comm...

Principal Investigator: Sheldon, Tom
Licensed Year(s): 2004
Summary: The deepwater sculpin is a small species of fish found only in the deepest lakes in Canada. Its closest relative is the marine fourhorn sculpin which is distributed in shallow marine waters of the arctic North American coast. To resolve the issue of orig...

Principal Investigator: Pratt, Brian R.
Licensed Year(s): 2012 2002 2000 1998
Summary: The researcher will study half a billion year old rocks in the Mackenzie Mountains, chartering a helicopter from Watson Lake to install and move light-weight camps and bring back samples. The strata of interest are exposed on mountain sides in remote are...

Principal Investigator: Moore, Steve M
Licensed Year(s): 2002 2001 2000
Summary: This study will gather baseline information on wildlife and vegetation to help fulfill step 5 of the protected areas strategy process. Two people (Steve Moore and one guide from Deline) will travel by boat from Deline to Edacho Peninsula and spend six days collecting baseline information on wildlife and ecosystem units. Thirty-six sites will be assessed and classified to ecosystem type. For eac...
