Abstract Temperature is one of those physicochemical parameters that affect zooplankton dynamics, including their distribution and abundance. Changes in temperature in aquatic ecosystems usually affect the metabolic reactions in their body. Though, their distributions signify status of such water body. This study was carried out to evaluate the effects of temperature on zooplankton distribution of River Rima. Zooplankton samples were collected from three sampling points designed for the study. Samples of both zooplankton and water were collected in the morning and afternoon. Standard methods were used during the sample collection. Zooplankton samples were identified using standard identification keys and water physicochemical parameters were measured insitu and others in the laboratory. Results revealed that four groups of zooplankton were available in River Rima, represented by 25 species. The two dominant groups were; Cladocera (72 %) and Crustacera (16 %). Results also indicated a low distribution of zooplankton at temperature =31.6 0C and the least temperature recorded was of 29.8 0C, which has more distribution of these zooplanktons. Therefore, to study these zooplankton species, a low daytime temperature should be targeted. |
