Composition and seasonality of nocturnal peracarid zooplankton from coastal New Hampshire (USA) waters, 19781980
Environmental Protection Commission of Hillsborough County 1410 N. 21st Street, Tampa, FL 33605, USA
Received on June 7, 1995; accepted on January 15, 1996 Seasonal changes in the nocturnal peracarid zooplankton from a nearshore area of the Gulf of Maine were studied from January 1978 through December 1980 as a requirement of an ecological monitoring program for the Public Service Company of New Hampshire's Seabrook Generating Stanon. Numerically dominant species included the mysids Michteimysis mixta and Neomysis americana. the amphipods Pontogeneia inermis, Themisto gaudichaudi and Monoculodes edwardsi. and the cumaceans Diastylis polita and Lamprops quadriplicata. A general seasonal cycle was documented with a more abundant and speciose assemblage during fall and winter than summer. Peak abundance occurred during spring months prior to emigration of juvenile M.mixta from the study area. Abiotic and biotic factors which may affect the structure and composition of this assemblage are discussed.
