- Abstract
In this study, the concept of functional feeding groups was used to classify macroinvertebrate community structure. A total of 55 genera or species were sampled in the Tuanjie Reservoir in China and identified into six functional feeding groups. The mean values of water transparency (SD), dissolved oxygen (DO), pH, water temperature (T), total phosphorus (TP), chemical oxygen demand (CODMn), dissolved copper (Cu2+), depth (D), electrical conductivity (EC), total nitrogen (TN) and dissolved iron (Fe3+) showed significant difference between sampling sites (P<0.05), while ammonium nitrogen (NH4+-N) and nitrate nitrogen (NO3--N) were not significantly different (P>0.05). Macroinvertebrate samples were also different, we find that the highest abundance was observed in summer at all sampling sites except S5 which was documented in spring, while the lowest abundance recorded in autumn except for S1 (in spring). Pearson and redundancy analysis (RDA) results showed that T, NH4+-N, Fe3+, DO and CODMn were the major factors influencing zooplankton functional groups in Tuanjie Reservoir.
