摘要:
Three years of observations on a population of Notomastus latericeus SARS from Acquatina lagoon (Lecce, Italy) are reported. The population dynamics, life cycle, and reproduction were investigated in order to explain periodic density variations of this species. Some physical parameters of the water column were measured and sediment analyses were performed to characterize the environment. Secondary production was also estimated as part of a functional study of the benthic system in the Acquatina lagoon. The species is opportunistic; its density is apparently Correlated to variation in salinity, but its presence in the lagoon is dependent on recruitment success and competition with other polychaete species.
