POPULATION DYNAMICS AND SECONDARY PRODUCTION OF NEREIS OLIGOHALINA (NEREIDIDAE: POLYCHAETA) FROMA SUBTROPICAL MARSH IN SOUTHEAST BRAZIL

摘要

The population dynamics and production of Nereis oligohalina Rioja, one of the nu- merically dominant macrofaunal species in salt marshes of SE Brazil, were studied from May 1987 to June 1988 in Paranagua Bay. Despite large fluctuations in population den- Sity (490 ind 0.45 m~-2 in June 1987 to 15 ind 0.45 m~-2 in February 1988), N.
