dc.description.abstractFrom 2003 to 2008, research on spatial and temporal dynamics of Corbicula fluminea was conducted at 10 sites along the Mondego Estuary (Portugal). A clear spatial and temporal variation in terms of density and biomass was observed, the highest values being found in the upstream oligohaline site, especially in warmer seasons. Seasonal density ranged from 4 to 11 500 individuals m22 . Biomass ranged from 0.01 to 323 g ash-free dry weight m22 . Comparing the results collected in the Mondego Estuary with other European and American invaded ecosystems, the density values are extremely high, but the biomass is lower than some of the reported values. This can be explained by the dominance of very small animals in the Mondego Estuary. Furthermore, the stepwise multiple regression model combining environmental variables and biomass of C. fluminea predicted that the areas with higher values of temperature and phosphate, together with lower values of salinity, water flow and silt and clay, support higher biomass. In 2005, a large reduction in density was recorded and was related to the massive mortality of small individuals as a consequence of the severe drought that occurred in the Mondego Estuarypor
dc.description.sponsorshipThe dataset used was obtained as part of the research project RECONNECT (PTDC/MAR/64627/2006) and the study was subsidized by the European Social Fund and MCTES Portuguese National Funds (QREN and POPH: Human Potential Operational Program – NSRF: National Strategic Reference Framework 4.4), by contract to J. Patrı´cio and J.M. Neto. Special thanks are addressed to all colleagues from IMAR-CMA that assisted in field and laboratory work and to the two anonymous referees for their suggestions.por
