Última Physiological and cellular responses in two populations of the mussel Perna perna collected at different sites from the coast of São Paulo, Brazil BABT Abessa,Denis Moledo de Souza; Zaroni,Letícia Pires; Sousa,Eduinetty Ceci Pereira Moreira de; Gasparro,Marcia Regina; Pereira,Camilo Dias Seabra; Rachid,Bauer Rodarte de Figueredo; Depledge,Michael; King,Rebecca Susan. The physiological conditions of mussels from Ubatuba and Santos and also of organisms transplanted from Ubatuba to Santos were studied by using different techniques. Assays for lysosomal stability were conducted on the haemolymph. Heart rate activity was monitored for 6h. The embryonic development of larvae obtained from the collected mussels was analysed. For all the compared groups of mussels, no significant differences were observed for the cardiac activity monitoring and the embryonic bioassays. The mean Neutral Red (NR) retention time was similar for the animals from Santos and Ubatuba, whereas the organisms transplanted to Santos showed a reduction in the retention time of the dye, indicating damage in the lysosomal membranes. These differences were... Tipo: Info:eu-repo/semantics/article Palavras-chave: Perna perna; Neutral red retention assay; Capmon system; Embryonic assay; Biomarkers; Physiology.

São Paulo, Brazil BABT Sousa,Eduinetty Ceci Pereira Moreira de; Tommasi,Luiz Roberto; David,Carlos João. The present study aimed to evaluate the seasonal variation of microphytobenthic biomass and its primary production in the intertidal zone in Santos Estuary (São Paulo, Brazil). This estuary is on the tropical region and it is regarded as a polluted area. The samples were collected at 3 sites, and environmental parameters, nutrients and heavy metals were analyzed. The primary production was evaluated according to GRφNTVED (1960) method whereas chlorophyll a and phaeopigment a were estimated by TETT et al. (1975) method. Total nitrogen K ranged from 20.0 to 115.0 µg·g-1 while total phosphate ranged from 26.0 to 223.0 µg·g-1. No significant seasonal variation of benthic primary production or chlorophyll a and phaeopigment a were observed. Significant positive...
