PH Fig. 2. 96 hr LC50 plots for pH for six species of freshwater mollusks in static laboratory bioassays. Data are from Mackie (1986). waters with alkalinities less than about 20 mg CaCo31"1. E. complanata exhibits another type of response where the shell becomes increasingly thinner as acidification proceeds. In fact, some populations in low-alkalinity lakes of southern On- tario have such thin shells that they are difficult to pick up without pushing the fingers through the shell. It is possible that dissolution of calcium carbonate from the shell may be buffering the excess hydrogen ions within the internal milieu of the clam. Perhaps the most significant effect of decreasing pH and alkalinities is the decreased reproductive capacities of mollusks. Rooke and Mackie (1984c) reported reduced pro- duction of eggs and extramarsupial larvae in Amnicola limosa + £ .? S
