Rotifer Species in Shantou, China
Rotifers, small but essential invertebrates in aquatic
ecosystems, are sensitive to environmental changes and are proposed to
be indicators of trophic state. Our results indicated that hydrological
heterogeneity is the macro-factor that regulates rotifer community
structures in the Shantou City area.
It is necessary to combine the rotifer
community structure and the Carlson’s trophic state index in water
quality assessment. Rotifer abundance alone failed compare the trophic
status with different water bodies because of the effects of
hydrological conditions. It is more efficient to use rotifer
composition, including B/T, KIN and TSIROT indices in water
quality assessment when comparing different water bodies.
