Spatial Dynamics of Mesocyclops edax (S. A. FORBES), Tropocyclops prasinus mexicanus KIEFER,Diaptomus pallidus HERRICK,Ceriodaphnia lacustris (BIRGE), Bosmina longirostris (O. F. MÜLLER), Daphnia parvula (FORDYCE) and Nauplii in a Northeastern Ohio Pond

A hypothesis on spatial dynamics of pelagic crustacean plankters was tested with the copepods and cladocerans of Squire Pond, Ohio. There was an agreement between the expected and the observed pattern of overall horizontal distribution in most instances for Mesocyclops edax, Tropocyclops prasinus mexicanus, Ceriodaphnia lacustris, Bosmina longirostris and nauplii, but only in a few instances for Diaptomus pallidus and Daphnia parvula. Windward accumulation was common for the first 4 species and near uniform distribution was frequent for the nauplii. Vertical-distribution trend along transect for all species rarely corresponded with the expectation. Alternation of modal depth along transect was one of the most frequently observed trends. Ways to test the hypothesis in the future are discussed.
