The Relationship

We found no significant differences in slope or intercept for the regression of loge fecundity on loge fork length among samples of whitefish from four lakes near Yellowknife in the Northwest Territories. The equation describing the relationship between fecundity and fork length for these populations was:[Formula: see text]Five other populations for which length–fecundity relationships could be calculated had length exponents ranging from 3.20 to 4.38, suggesting a nonlinear relationship between weight and fecundity. Six of the nine populations as well as four others for which limited data were available all had similar relative fecundities. Fish from Buck Lake in Alberta and from Lake Erie had high relative fecundities while fish from Great Slave Lake had low relative fecundity.

History Of

Two alkaline igneous complexes and three lines of diatreme breccias were emplaced in the East Arm of Great Slave Lake during the lower Proterozoic. Field relationships suggest that those rocks are broadly cogenetic and were emplaced about 2.1 Ga ago.One of the intrusions, the Easter Island dyke, was rotated subsequent to emplacement such that both top and bottom are now exposed. Field and petrographic data are indicative of progressive differentiation along (i.e., up) the dyke and are substantiated by chemical data. The differentiation history of the early gabbros of the Blachford Lake complex is similar. Late differentiates of both complexes closely resemble the igneous matrices of the breccias and petrographic and chemical data support the proposal of cogenesis and contemporaneity.The field data show that there was a period of significant faulting and concomitant alkaline igneous activity in the East Arm area in the lower Proterozoic.

The City

Coyotes (Canis latrans) have resided in the Northwest Territories for several decades but have only rarely been sighted north of Great Slave Lake (>62° N. latitude) in the Taiga Shield ecozone. Records show Coyotes have been seen since the 1960s. Prior to 2000, evidence of Coyotes breeding in the Taiga Shield has been anecdotal. In 2000, a Coyote was repeatedly seen at the Yellowknife airport and in 2001, a pair of Coyotes was observed with two pups. Since then, Coyote pups have been observed annually at the airport and adult Coyotes are seen regularly within the city of Yellowknife, an urban island within the Taiga Shield ecozone. Unlike in most regions occupied by Coyotes, medium-sized prey are rarely seen. Recently, Coyotes have become a potential hazard to aircraft at the Yellowknife airport. Although Coyotes appear to have established themselves within the city of Yellowknife, maintaining a presence beyond the urbanized area remains uncertain.
