Abstract

The investigation of plankton diversity and their distribution in relation to the environmental conditions of a rare temporary water habitat (rock pool) in Upeh Guling, Endau Rompin, Johor, Malaysia, was undertaken. Samples were collected on a monthly basis for a period of one year. However, due to flash flooding during rainy season, sample collection was only possible for a period of six months (between March and September 2013). Plankton samples were collected from four stations representing two different conditions of the sampling area: (1) river fed rock pools which receive water primarily from the river (2) rain fed rock pools, which receive water primarily from rainfall. Physico-chemical parameters: temperature, pH, and dissolved oxygen were measured in situ. A total of 122 species of phytoplankton were recorded with 116 species at rain fed rock pools and 84 species at river fed rock pools. The most diverse phytoplankton genus was Staurastrum with 10 species. On the other hand, a total of 49 species of zooplankton were recorded with 48 species at rain fed rock pools and 40 species at river fed rock pools. The most diverse zooplankton genus was Lecane with 11 species in total. For both the phytoplankton and zooplankton, the rain fed rock pools recorded higher (P<0.05) variation in total species diversity and density, compared with river fed rock pools. High species diversity index in both rain fed and river fed rock pools, ranging from H'=3.14-H'=3.56 as a result of long period of inundation which suggested healthy condition of the ecosystem. Similarly, the environmental parameters (24.50 – 29.20 °C, 4.2 – 6.9 mg/L and 5.3 – 8.2 unit) of both rock pools were within the favourable range and suitable for organisms conservation. The canonical correspondence analysis ordination revealed that the water depth, which was controlled by unexpected rain fall, was the major factor in both rock pools that contributed to plankton diversities. The months of June, July and August recorded highest species similarity in composition and distribution due to the pools stability in these months. These all favours the proliferation of diverse species of phytoplankton and zooplankton.
