August 1990 to August 1991. Investigations were focused on species composition, seasonal variation, vertical and horizontal distribution and the size class distribution in the population structure of' zooplankton. Two species of cyclopoids, two species of calanoids,, nine species of' cladocerans and sixteen species of rotifers were recorded. Among these, the most abundant species duringthe study period were Mesocyclops sp., Phyllodiaptoin tts anime. Ceriodal-Vint'a cormita, Keratella troplea, Filina longiseta, Brachi(MIS caudatus and Tricocerce sinulis. A location at the deepest region of the reservol I' closer to the dam was selected as a representative station to investigate ffic vertical distribution of zooplankton. At this location, the vertical distribution patterns of all the zooplankton were almost similar throughout the year. As this location is situated at the down stream region of the river, it was expected to contain most of the zooplankton of the reservoir. The horizontal distribution of' zooplankton did not show much variation. The nauplii stages and cyclopolds showed hio-hest abundance In the population of zooplankton. However, during most of the months, the adult stages of calanoids and cladocerans were highly abundantItem Amphibian declines and possible etiologies:the case for Sri Lanka(National Science Foundation:Colombo, 2007-3) Rajakaruna, R.S.; Samarawickrama, V.A.M.P.K.; Ranawana, K.B.Item Recent developments in angiosperm phylogeny and classification in the light of molecular data and cladistics(National Science Foundation:Colombo, 2006) Yakandawala, D.Item Effect of acetylcholine on the contractility of the vas deferens and epididymis and on fertility of male rats(National Science Council:Colombo, 1986) Ratnasooriya, W.D.Item Eco-cultural diversity embedded in the cultural landscape:an approach to biosphere reserve management(National Science Foundation:Colombo, 2003) Ramakrishnan, P.S.Item A survey of rice-field weeds in Ratnapura and Kurunegala districts of Sri Lanka(Natural Resources Energy and Science Authority of Sri Lanka:Colombo, 1989) Chandrasena, J.P.N.R.Item Mosquito-larvicidal activity of Ceylon citronella {Cymbopogon Nardus (L.)
