“…Two fairly dense populations of sphaeriids in the St Lawrence River produced only 1.2–13.3 g DM m −2 year −1 of shell (Vincent et al. , 1981; Vincent & Lafontaine, 1984). From these estimates, it seems doubtful that even dense populations of sphaeriids produce >100 g DM m −2 year −1 of shell.…”

“…Nevertheless, the very few measurements that have been made of either shell production (Aldridge & McMahon, 1978; Strayer et al. , 1981; Vincent, Vaillancourt & Lafontaine, 1981; Vincent & Lafontaine, 1984) or decay (Strayer et al. , 1981) by freshwater bivalves are insufficient to evaluate the importance of habitat engineering by freshwater bivalves across environments or species.…”

SUMMARY1. Spent shells of bivalves can provide habitat for other organisms, as well as playing important roles in biogeochemical cycles. The amount of spent shell material that will accumulate at a site depends on rates of both shell production and decay, although the latter is rarely considered. 2. We measured the instantaneous decay rates of four species of freshwater bivalves across a range of sites in south-eastern New York, and found that rates varied by more than 500-fold across sites and species. 3. Differences in decay rates were related to water chemistry (Ca, pH, dissolved inorganic C), the presence of a current, and the size of the bivalve shell. 4. Combining these decay rates with estimates of shell production derived from the literature, we conclude that the Unionidae, Corbicula, and Dreissena are all capable of producing large accumulations (>10 kg dry mass m )2 ) of spent shells, while members of the Sphaeriidae probably rarely will produce such large accumulations. 5. Hence the replacement of native unionid bivalves by the alien Corbicula and Dreissena may have little effect on standing stocks of spent shells, unless the aliens invade sites where unionids are scarce or absent.

“…C'est en particulier le cas pour les variations a court terme (mensuelles) dans des milieux tels que le Saint-Laurent o la rigueur du climat rend difficile l'acquisition de donnees pendant plus de la moiti6 de l'ann6e, de la prise des glaces a la fin de la debacle; c'est pourtant dans de ces milieux que de telles tudes semblent les plus int6ressants. De telles donn6es, couplees plusieurs tudes de dynamique de populations (McMurray et al, 1982;Vincent & Lafontaine, 1984;Vincent et al, 1981a, b) et une tude spatiale (Vincent, 1979) ont cependant pu tre obtenues pour la zone littorale du Saint-Laurent et elles seront present6es ici. Cette zone littorale presente l'interet d'etre tres riche, d'occuper de grandes superficies mais aussi d'etre la plus exposee h l'ensemble des principales perturbations affectant ce cours d'eau.…”

Monthly variations of macrobenthic communities were studied in three sites and during 13 months in the littoral zone of the St-Lawrence River (Qu6bec) where there are steep seasonal gradients of temperature and formation of an ice-foot during the long hivernal period. There is a good spatial distinction between the three benthic communities for all the year, except with the diversity index. Our results confirm the principal conclusions of precedent spatial and/or seasonal studies concerning means and temporal variability of uni-and multidimensional descriptors of community structure. Principal temporal discontinuities are observed during spring and are mainly explained by reproduction of dominant species, by migration of Gastropods between macrophytes and sediments and by emergence of Chironomids. During the six months of the hivernal period, there is a regular diminution of spatial heterogeneity in the littoral zone, temporal variations are weak and ice-foot do not affect community profiles. However, differences between thermal regime of the two years explain important variations at the community and at the population level. This inter-annual variations of the communities organisation are probably slowly compensated by interspecific competition as they were slowly compensated by intra-and interspecific competition at the population level.
