Abstract | Over a two year study period, zooplankton was sampled in Gazi Bay, Kenya, using a 335 mu m mesh size Bongo net. Two Way Indicator Species Analysis (TWINSPAN) classification demonstrated that rainfall and tidal regime had substantial influence on the zooplankton community structure. Samples collected during the rainy season clustered together when treated with TWINSPAN. Furthermore, the clustering was more pronounced for neap tide samples than for spring tide ones. Samples obtained during spring tide did not give a clear cut pattern. Canonical Correspondence Analysis (C.C.A.) confirmed these findings, a clustering together of rainy/neap tide samples; and little separation (based on environmental variables) between sampling stations. |
