The ecology and paleoecology of benthic macroinvertebrates in the Mackenzie Delta region
chercheur principal: Quinlan, Roberto
Année(s) de permis: 2017 2016 2015 2014 2013
Résumé: This study will examine the effects of permafrost and flooding on the ecological structure of contrasting lakes in the Mackenzie River Delta. Patterned ground marked by ice-wedge polygons is formed by freezing and thawing of the soil, which forms cracks into which ice can spread and cause the soil to uplift. These processes have effects on the hydrology and water chemistry of adjacent aquatic envi...

Environmental Studies of the Aquatic Resources of Spyder Lake.
chercheur principal: Reed, Shawna
Année(s) de permis: 1994
Résumé: The researcher will determine fish presence/absence and/or densities (number of fish per unit stream length) by electrofishing representative habitat (eg. pool, riffle, run) and the setting of baited minnow traps. When these two methods are not practical (eg. depth too great or flow too fast), gillnets and/or beach seines will be used. Fish caught will be identified, measured, weighed, sexed and t...


Environmental Studies of the Aquatic Resources in the Lac de Gras Area.
chercheur principal: Pelletier, Clem
Année(s) de permis: 1994
Résumé: In project area streams, fish presence/absence and/or densities will be obtained by electrofishing representative habitat. Benthic invertebrates ans periphyton (stream algae) will be sampled at stream sites to determine seasonal changes in composition, distribution and abundance. Lake fisheries population studies will involve fish trapping. Lake limnology, plankton and benthic invertebrates wil...
