Predation on rotifers by the suspension-feeding calanoid copepod Diaptomus
Consumer growth response of selected model species (Chlamydomonas, Selenastrum, Brachionus, Diaptomus
, Daphnia, Drosophila) will be measured at each level in terms of: ribosomal DNA genes and intergenic spacers; genome size; nucleic acid and protein content; cell size; body size and elemental composition; and growth rates.
Black crappie displayed a population feeding pattern in which Diaptomus
and Cyclops each represented nearly 50% of the prey consumed by the sample population and Daphnia was consumed in low abundance (Fig.

, and Eurytemora species, were found (Selkere, 1955).
pulex is present in a pond, the only other species found are the two ubiquitous Arctic copepods Cyclops scutifer and Diaptomus

Moreover, the other intermediary hosts of the fish tapeworm, the calanoid copepods Diaptomus
diabolicus and Boeckela gracilipes, are also abundant (16).
Of the two calanoid copepod genera, Diaptomus
abundances exceeded Eurytemora abundances for the periods August through November 1996 and midMay through mid-June 1997 (Fig.
oregonensis and the juvenile copepod stages) to the omnivorous Orthocyclops modestus, which can prey on rotifers, juvenile copepods, and small cladocerans.
Growth was positively correlated to biomass of Hemiptera, Trichoptera, Coleoptera, Ceriodaphnia, Daphnia, and Diaptomus
and negatively related to biomass of Chironomidae larvae (Table 5).
