Abstract
We studied the newly-created Shiroro lake, Nigeria, at the extremes of its hydrological cycle: high water level (HWL) and low water level (LWL). Temperatures reflected prevailing weather conditions; pH, dissolved oxygen, turbidity and suspended solids were highest during HWL, but transparency, conductivity, NO3−-N, PO43−-P and Na+ were higher during LWL. A total of twenty-six species of pelagic zooplankton were identified: five species of cladocerans, eight species of copepods, and thirteen species of rotifers. The freshwater medusa (Limnocnida) and Daphnia longispina were absent during HWL but present at LWL, suggesting seasonality of the zooplankton community. Thermocyclops consimilis and T. emini are new records for Nigeria, bringing to nine the number of known Thermocyclops species in Nigeria.
