摘 要(英文)： Enclosure experiments with three treatments (sediment addition,
sediment + nitrogen enrichment, sediment + phosphorus enrichment)
and unfertilized controls were performed in shallow hypereutrophic
Lake Donghu during the summer of 2000. Dense Microcystis
aeruginosa blooms occurred in all the enclosures during the
experimental period but not in the surrounding lake water.
Generally, the dominant rotifers were Polyarthra vulgalis, Filinia
longiseta, Proales sp. and Asplanchna sp. at the beginning of the
experiment, followed by a shift to Brachionus calyciflorus,
Trichocerca similis, Cephalodella catellina and Anuraeopsis fissa,
and finally to F. longiseta, Proales sp. and Keratella cochlearis.
M. aeruginosa blooms strongly suppressed the larger Diaphanosoma
brachyurum but enhanced the development of the smaller cladocerans
and rotifers that probably efficiently utilized organic matter
from M. aeruginosa through the detritus food chain. The smaller
cladoceran and rotifers coexisted successfully throughout the
experimental period.
