WebDiaptomus shoshone was found here in 30 of 32 sampled years, at densities ranging from 0.02–2.40/L; Chaoborus americanus appeared only twice (1979 and 1986; Table 1) and … WebI've never seen anything like these lakes in the Crazies. We've been to three of them by now, sampling the zoo-plankton populations, and not only are the plankton populations high for a mountain lake, hundreds per liter of water, but they're also dominated by a single, bright red Copepod (Diaptomus shoshone).

Some factors influencing size of Diaptomus shoshonel

Diaptomus is a genus of copepods with a single eye spot. It is superficially similar in size and appearance to Cyclops. However it has characteristically very long first antennae that exceed the body length. In addition, the females carry the eggs in a single sac rather than the twin sacs seen in Cyclops. It is a copepod of larger freshwater ponds, lakes and still waters. Webcopepod (Diaptomus shoshone), four harbored Daphnia middendorffiana and two had Daphnia pulex. The numbers of zooplankton had little correlation with the presence or absence of fish; however, preliminary analysis of the data suggests that population density of large zooplankton are influenced by fish density. optmatchとは
