Abstract
    In the laboratory we examined the effect of pH (5–10 with one interval) on survival, reproduction, egg viability and growth rate (intrinsic growth rate—r m and population growth rate—r) of five Brachionus rotifer species (Bcalyciflorus, Bquadridentatus, Burceolaris, B. patulus and Bangularis). The pH was shown to exert a major influence on egg viability and growth rate (r m and r) for each species. The age-specific survivorship curves within a species were not significantly different at pH 6–10. The optimal pH for each species is near-neutral pH (pH 6–8), and the fecundity decreased as the pH deviated from these values. For each Brachionus species, there was no significant difference between age-specific fecundity curves at pH 7 and 8. At acid pH (pH 5 or 6) higher egg mortality was observed for each species. The r m and population r of the five Brachionus species incubated at different pHs were significantly influenced by pH. The pH supporting the highest r m or r was obtained at pH 6–8, but varied due to species. In this study Burceolaris and Bpatulus could tolerate a broad range of pH, while the populations of Bcalyciflorus, Bquadridentatus and Bangulari declined at acid conditions.
