Use of the morphoedaphic index to predict nutrient status and algal biomass in some Canadian lakes
The underlying assumptions of the morphsedaphic index (MEI; total dissolved solids (TBS)/rnean depth), which has been used to predict fish yields in lakes, and its power for predicting biomass at lower trophic levels were examined using published data. The assumptions included… Read More
An empirical model to predict in situ grazing rate of Diaptomus minutus Lilljeborg on small algal particles
Grazing rates of Diaptornus minuaus were measured in situ in six lakes in south-central Ontario using the tracer species Chlorella vulgaris and Scenedesmus ova%isA. n empiricat model was constructed to predict grazing rate as a function of the relative proportion of small (Read More
Factors regulating in situ filtering rates of Cladocera
Individual filtering rates of four species of Daphnia, as well as Holopedium, Diaphanosoma, Ceriodaphnia, and Bssmina, were measured in 10 lakes under various field conditions to identify important factors regulating in situ filter-feeding for these cladocerans. Linear regression… Read More
