Regional synchrony of lemming populations in the northern Yukon and Tuktoyaktuk region
Principal Investigator: Krebs, Charles
Licenced Year(s): 1993 1992 1991
Summary: The researchers will examine the cycles in lemming abundance (i.e., increases and decreases in the lemming population) for the western arctic region. Ongoing research suggests that lemmings in the Pearce Point area do not appear to reach very high numbers as has been noted in the eastern arctic and Scandinavia. Licence issued for use of Inuvik Research Centre....


Bathymetry of Lac Belot
Principal Investigator: Lockhart, W.L.
Licenced Year(s): 1993 1992
Summary: The researcher and his team will engage in a bathymetric survey to map the contours of the bottom of Lac Belot, as well as determine the distribution of fish in the lake. Several soil samples will be collected to determine the amount of atmospheric dust fallout. As well, tissue samples from 6 lake trout and 6 ground squirrels are to be collected to compare some aspects of their biochemistry with ...
