AB  - The phytoplankton and physico-chemical
characteristics of Shadawanka river Nigeria were
monitored to determine the impact of change of some
parameters on the distribution, species richness, relative
abundance and diversity of phytoplankton composition.
Water was sampled and analysed for both Biological and
physico-chemical characteristics of the river. Three
major components were identified that influence the
physico-chemistry of the water, namely: rainfall,
dissolved, oxygen and ionic composition. However, the
result revealed that, the Bacillariophyceae (pinnate
diatoms) had the highest abundance in all the stations,
seasons and communities followed by Chlorophyceae
which tended to decline with increase in flow and with
reduction in nutrients and few species of Euglenophyceae
dominated the total algal biomass. Correlation analysis
showed that, harmful algal biomass increased with
increase in total algal biomass. Total Dissolved Solids
(TDS), Dissolved Oxygen (DO), Biochemical Oxygen
Demand (BOD) and pH were generally high during the
dry season. pH increases with increase in electrical
conductivity and rainfall. DO increases with increase in
rainfall and BOD.
