| 中文摘要 | The changes of cladoceran zooplankton from 1980 to 1996 were studied in a hypereutrophic subtropical Chinese lake, Lake Donghu, and an enclosure experiment was conducted to examine the possible role of the increased fish production in the enhancement of Moina micrura in the lake after mid-1980s. During the 1980s, the most striking event of the cladoceran community in the lake was that dominance of Daphnia was replaced by Moina following a steady increase in the production of planktivorous fish. This replacement was a direct result of increased fish predation, since our enclosure experiment indicates that Moina are less vulnerable to fish predation than Daphnia, and that increase in fish-stocking rate favors the development of M. micrura. The stronger resistance of M. micrura to fish predation may be attributed to its smaller body size and higher intrinsic growth rate than the daphnids. The present study has a strong parallel with the responses of zooplankton community to predators observed in many temperate lakes, and perhaps the only real difference is that in our lake the small rapidly growing cladoceran is Moina, rather than Bosmina or some other typical temperate take species. In the present study, the strong fish predation caused a shift from Daphnia to small zooplankton but not a corresponding increase in phytoplankton, which is in sharp contrast to what is expected with the classic "trophic cascade" process. |
