Abstract
Species diversity and community assemblage of planktonic rotifers were
determined with respect to seasonal variations in a pond of Pipnakha village,
Gujranwala. Sampling was executed on monthly basis at three sites of the pond
from October, 2011 to September, 2012. Altogether, 74 rotifers belonging to 24
genera and 13 families were identified. Highest (128.7±40 ind/ml) ppopulation
density of rotifers was observed in June while lowest (64.9±22 ind/ml) population
density was seen in January. Brachionus havanaensis was found to the the
dominant species with the highest mean population density (40±11.9 ind/ml) while
Philodina roseola was a least dominant with lowest population density (3±1.2
ind/ml). ANOVA displayed a significant difference in population density of rotifers
among months. Rotifers exhibited positive correlations with temperature, total
hardness pH, TDS, electrical conductivity and turbidity however, DO and
transparency indicated negative correlations. Shannon-Weaver index stretched
from 3.036 to 3.802 and exhibited great diversity. Values o
