The effect of handling and acclimation period on the grazing rate of Daphnia and Diaptomus
Grazing rates of Daphnia sp. and Diaptomus oregonensis measured using an in situ method (Haney 1971) were compared with rates measured by collecting animals in vertical townets and placing them in experimental chambers either immediately or after a 24-h acclimation period.… 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
