Abstract EN
Changes in the density and species composition of planktonic rotifers as well as their relationship to several environmental variables were studied at Dadian Lake, a shallow subtropical lake, which was completely dredged and reconstructed.
Samples were taken monthly (2006–2009) at five stations.
The total rotifer abundance exponentially declined and reached a relatively stable stage in 2009.
Polyarthra dolichoptera and Trichocerca pusilla dominated the rotifer community in most seasons.
TN, TP, and CODMn went down at the beginning of the monitoring period, rebounded in the second winter, and then decreased and reached a stable state in 2009.
CCA showed that the most significant variations were caused by fluctuations in temperature, CODMn, SRP, and NO2-N.
The rotifer community experienced a two-stage succession and the difference of species between the stages was exhibited during warm seasons.
GAMs indicated that the selected factors were responsible for 64.8% of the total rotifer abundance variance and 16.5~64.3% of the variances of individual species abundance.
Most of the environmental parameters had effects on rotifer abundance that could only be described by complicated curves, characterised by unimodality and bimodality instead of linearity.
Our study highlighted the temperature influence on rotifer species composition and total abundance in subtropical lakes.
