Distribution of Dark-Celled Fungal Root Endophytes Along an Arctic to Boreal Latitudinal Gradient
chercheur principal: Piercey, Melissa
Année(s) de permis: 2000
Résumé: Roots of plants inhabiting cold-stressed environments are often colonized by vegetatively reproducing fungi. The researcher will examine the genetic variation within and among populations of Phialocephala fortinii P. along a latitudinal gradient encompassing the boreal, subarctic and arctic zones in Northern Canada. The researcher will travel from Yellowknife to 3 study sites surrounding Great ...

Trilobite biostratigraphy of Rockslide Formation (Middle Cambrian)
chercheur principal: Pratt, Brian R.
Année(s) de permis: 2012 2002 2000 1998
Résumé: Outcrops in the Mackenzie Mountains preserve an almost uninterrupted sequence of strata of Cambrian age. This study aims to collect in bed-by-bed detail the trilobite fossils from the Rockslide Formation, the Middle Cambrian portion of the sequence. The taxonomy and biostratigraphy of these fossils will generate a refined time scale for this part of the geologic column, some half a billion years o...

Genetic Diversity in the Biota of Arctic Lakes
chercheur principal: Hebert, Paul
Année(s) de permis: 1997
Résumé: Our research will involve the survey of zooplankton communities in lakes and ponds of the Mackenzie Delta area (Inuvialuit private lands). Samples will be collected by either wading in ponds or by towing at net behind a float equipped helicopter. Samples will be frozen in liquid nitrogen, and subsequently examined for genetic variation. Our work aims to establish the species diversity of zoopla...

Investigation of Distribution and Range Boundaries for Some Common Subarctic Inscects Occuring at or Near Treeline
chercheur principal: Royer, Ronald A.
Année(s) de permis: 1995
Résumé: The researcher will investigate range boundaries and species intergrade zones. The researcher will also possibly define ecological limiting factors for selected apecies of common arctic insects, principally in the order of Lepidoptera. This data will fill numerous gaps in understanding of distribution and speciation for the targeted species, the ranges of many of which are assumed but not yet co...

Ranch Lake Environmental Base-line Study
chercheur principal: Somji, Feisal
Année(s) de permis: 1995
Résumé: The researcher will conduct an intensive gillnetting program using multi-mesh gillnet gangs to determine the size and characteristics of fish populaitons in the project area. Both floating and bottom sets will be used, perpendicular and parallel to the shoreline. It is proposed that 40 fish of each species found will be taken from each lake sampled....

Permo-Triassic Vertebrates from Axel Heiberg and Ellesmere Islands, Northwest Territories.
chercheur principal: Gardner, James D.
Année(s) de permis: 1994
Résumé: The researcher will examine the following geological localities and units: Sabine Bay (Permian) and Heiberg (Triassic) formations, northern Axel Heiberg Island and Blind Fiord, Blaa Mountain, and Heiberg and Sabine Bay and Svartevaeg formations, east- central Ellesmere Island. At each fossil site the researcher will record relevant stratigraphic and sedimentological information and collect repres...

Collection of Inuit traditional knowledge of the distribution and biology of High Arctic beluga and narwhal
chercheur principal: Stewart, D. Bruce
Année(s) de permis: 1993
Résumé: The researchers will be documenting Inuit traditional knowledge of the distribution, abundance and biology of High Arctic beluga and narwhal. This information will be used to identify research and management needs for local and co-management plans. A questionnaire will be used to interview elders and hunters; the interviewer will be a community resident. Information will be compiled into a repo...

Shallow water benthic fish communities of Resolute Bay
chercheur principal: Green, John M.
Année(s) de permis: 1993 1990 1988
Résumé: As part of a long-term study, I will continue to make underwater observations of the benthic fishes found in the shallow waters of Resolute Bay. Some fish will be collected for further laboratory studies in order to examine their food habits, growth rates and population growth rates. The species Gymnelus viridis will be studied in greater detail....

Biology, ecology and cold tolerance of arctic insects
chercheur principal: Ring, Richard A.
Année(s) de permis: 1993 1992 1990 1987
Résumé: As part of a long term study, I will continue to examine the biology of arctic and subarctic insects. Information will be collected on insect distributions as well as insect adaptations to living in environments with extremely cold winters and short summers. Studies on insect communities in the north may be good indicators of global climate change since they are short-lived species with limited a...
