Abstract | An investigation of the prosobranch snail Brotia hainanensis (Brot, 1872) (Gastropoda: Thiaridae) in Tai Po Kau Forest Stream, New Territories, Hong Kong, has been undertaken with population samples collected at approximately 14-day intervals between August, 1977 and March, 1979. This species shows two peaks of recruitment per annum, one in spring and a second in the latter part of summer. Growth to sexual maturity is rapid, taking approximately 8.5 months, and in this respect, as well as its dual peak of recruitment, B. hainanensis displayed some variation from the iteroparous pattern of life cycles considered to be characteristic of freshwater prosobranch snails. Mortality after the young snails reach maturity is high due to severe seasonal spates in the stream and it is suggested that the modification of the life cycle of B. hainanensis from the type more usually encountered in freshwater prosobranchs reflects that this is an r-selected species adapted to a habitat where high density-independent mortality occurs. © 1982. |
