| Response-species of zooplankton on precipitation and temperature were investigated in the tributatries of Han River from May to November, 2002. Total 42 species (Rotifer twenty three species, chadocera ten species, Copepoda eight species and Protozoa one species) were collected in the target location. The highest abundance and the number of species were observed in May. Due to the summer precipitation the abundance of Rotifer and Cladocera were largely decreased in August. Dominant species of Rotifer appeared Brachionus urceolaris, Euclanis dilatata, Lecane luna, Brachionus quadridentatus and Brachionus calyciflorus in May, Monostyla bulla and Conochilus unicornis in August and Brachionus quadridentatus, Euclanis dilatata and Lecane luna in November. Also, the dominant species of Cladocera were Moina weismanni, Simocephalus vetulus, Scapholebris mucronata, Chydorus sphaericus in May, Chydorus sphaericus, Scapholebris mucronata in August, Chydorus sphaericus and Alona rectangular in November. Nearest neighbour clustering was implemented for classification of zooplankton abundance in different month of survey locations. The patterning of May and November appeared similar but August was different. |
