dc.description.abstractThis study was set to determine the seasonal variations in the physical and chemical parameters of Imaboro River as well as the plankton, periphytic algae and macro benthic invertebrate community structure and dynamics of the river. Sample collection was done monthly from October, 2012 to September, 2013 (one year). The physico-chemical and biological parameters were analysed according to standard methods. Water temperature, pH and electrical conductivity were determined on the field. Dissolved oxygen (DO), biological oxygen demand (BOD), TDS, TSS and TS were determined at Chemistry Laboratory, Kogi State College of E ducation, Ankpa. Other analyses were done at Department of Biological Sciences Hydrobiology Laboratory, Ahmadu Bello University, Zaria. The study showed that temperature ranged between 23.24±0.39 and 28.36±0.190C, transparency between 39.80±9.16 and 59.30±9.41cm, TSS between 100.00±68.24 and 300.00±0.00 mg/l, TDS between 40.00±24.49 and 820.00±335.26 mg/l, velocity between 0.17±0.05 and 0.17±0.05 m/s. pH ranges between 5.75±0.11 and 6.19±0.17, EC between 17.80±3.54 and 34.60±10.27 μS/cm, DO between 2.96±0.17 and 4.62±0.45 mg/l, total hardness between 18.40±2.40 and 48.00±8.10 mg/l, alkalinity between 4.75±0.95 and 13.20±3.18 mg/l, NO3-N between 7.200±73 and 24.80±1.39 mg/l and PO4-P between 1.00±0.07 and 2.34±0.04 mg/l. The study revealed that the physico-chemical parameters vary significantly between stations and months of study. The community structure of the biological parameters studied showed no significant difference between stations and months. The canonical correspondent analysis (CCA) of the biological parameters showed a strong positive correlation between the species and the physico-chemical parameters. The dynamics of Imaboro river is a complex one showing some elements of organic pollution resulting from anthropogenic activities viii although most of the physico-chemical parameters studied fell within the tolerable limit. It was recommended that people should be sensitized on the danger of dumping refuse inside the river, molecular techniques be adopted for accurate identification of organisms, and further research be conducted to determine the heavy metal content of the river.en_US
