Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
Principal Investigator: Tonn, William
Licensed Year(s): 2014 2013 2012 2011 2010 2009
Summary: The objectives of this research project are: to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and to assess the effectiveness of such habitat modifications ...

Biogeochemistry of Lakes in the Mackenzie Delta
Principal Investigator: Lesack, Lance
Licensed Year(s): 2017 2016 2015 2014 2010 2009 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998 1997 1996 1995 1994 1993
Summary: Specific activities for this field season include the following: (1) Resolution of the sources and fates of dissolved organic carbon (DOC) in aquatic food webs of the Mackenzie Delta (year 3 of PhD thesis project of S. Tank). This information is needed to ultimately understand the relative role of bacterial (fueled by DOC) versus photosynthetic organisms and their importance in ultimately sup...

Environmental Studies of the Aquatic Resources of Spyder Lake.
Principal Investigator: Reed, Shawna
Licensed Year(s): 1994
Summary: 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.
Principal Investigator: Pelletier, Clem
Licensed Year(s): 1994
Summary: 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...

Environmental Studies of the Aquatic Resources in the Prairie Creek Area.
Principal Investigator: Reed, Shawna
Licensed Year(s): 1994
Summary: In project area creeks & streams, fish presence/absence and/ or densities will be obtained by electrofishing representative habitat & the setting of baited minnow traps. Each fish caught will be identified, measured, weighed & sexed, & condition will be noted. Furthermore, in order to assess background tissue metal levels, ten specimens of each species must be sacrificed in order to obtain the req...
