Factors Influencing Selected Littoral Fauna in Saline Lakes in Saskatchewan
The lakes of Saskatchewan provide an excellent arena in which to study the ability of organisms to live under severe conditions. This thesis is concerned with a study of some key factors influencing the distribution of selected animal species in the littoral habitat. The literature on atha1assic lakes (Verhies 1917, Young 1924, Thorpe 1931, Beadle 1932, Hutchinson 1937, Rawson and Moore 1944, Lauer 1963, Bayly and Williams 1966, Cole 1968, Scudder 1969a, Walker 1973, Hammer et ale 1975) clearly establishes the importance of salinity as a key factor in this environment. Whilst the relative importance of the direct effects of salinity compared to the indirect effects also remains unclarified, the direct effect of salinity, particularly in athalassic lakes is still little understood.
