摘要：

Three riverine habitats differed in ambient suspended particle concentration. Filtration rates were significantly different across the habitats, and were inversely correlated with the mean ambient suspended particle concentrations: 66.4 mL/h for 11 mg/L, 100.2 mL/h for 7 mg/L, and 144.9 mL/h for 4 mg/L for the Tombigbee, Ouachita and Tangipahoa rivers, respectively. However, the weight of particles filtered by clams from the 3 rivers was not significantly different. C. fluminea can make physiological adjustments to its filtration rate to achieve some "optimal' rate of particle removal. Filter feeding in C. fluminea is a complex phenomenon, requiring an understanding of how the physiological process of feeding is influenced by morphological constraints imposed upon gill functioning and by the temporal effects of environmental variables. The plasticity in the filter-feeding response and the capacity for alternative feeding modes contribute to the success of C. fluminea as an invasive species. -from Authors
