Fig. 2. Summer spatial distributions of outflow for the Rupert and inflow for the Pepeshquasati, Cheno, and Takwa populations of brook charr (Salvelinus fontinalis) in Mistassini Lake, according to scientific data from Fraser and Bernatchez (2005a). Genetic markers were used to assign individuals captured throughout the lake to their respective population of origin (details of methodology in Fraser and Bernatchez 2005a). Inflow populations are denoted in black because their spatial distributions did not differ from one another; the spatial distribution depicted is for the year 2001, but similar results were obtained for year 2000 (Fraser and Bernatchez 2005a). The size of the circles within the legend is proportional to the number of individuals assigned to populations at each sampling location.
