- Abstract
In order to determine the spatial and temporal relationship between environmental factors and zooplankton functional groups in the Harbin section of the Songhua River, China, we collected water samples of zooplankton separately at 6 sampling sites in spring, summer and autumn in 2012. In this study, a total of 26 species of zooplankton were collected from Harbin section of the Songhua River, belonging to 6 functional groups. Both environmental factors and the biomass of zooplankton functional groups exhibited spatial and seasonal differences. Water temperature (WT), chemical oxygen demand (CODcr), total phosphorus (TP), nitrate (NO3-) and dissolved iron (Fe3+) were significantly higher in summer. On the contrary, pH, dissolved oxygen (DO) and 5 days' biochemical oxygen demand (BOD5) were significantly lower in summer. The biomass of zooplankton functional groups was higher in spring and lower in summer. According to the results of Redundancy analysis (RDA): water temperature (WT), dissolved oxygen (DO), pH, chemical oxygen demand (CODcr), 5 days biochemical oxygen demand (BOD5), total phosphorus (TP), N: P ratio (N:P) and dissolved iron (Fe3+) were the major factors influencing zooplankton functions.
