Predation on rotifers by the suspension-feeding calanoid copepod Diaptomus
Preliminary report on six new species of Diaptomus
Life cycle of the parasite is indirect, involving two intermediate hosts, the first is a crustacean of genera Diaptomus
or Cyclops in which procercoid stage develops and second is a fresh water fish which harbour plerocercoid stage of the tapeworm.
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.

(Eubosmina) coregoni and Cyclops, Diaptomus
, 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

minutus using carotenoid pigments: a caution.
Also, experimental infection of two fish species (Cichlasoma synspilum, Poecilia reticulata), the Bullfrog (Rana catesbiana), and a copepod (Diaptomus
albuquerquensis) with second stage larvae of Dujardinascaris helicina yielded larvae only from 1 of 5 P.
