...ncluding 17 protozoa, 36 rotifera, 12 cladocera and 11 copepods species, respectively. Zooplankton species richness changed slightly in the four seasons but varied a lot in different positions. Protozoa was absolutely dominated in zooplankton abundance and its mean value ranged from 2710.2 ind./L in winter to 4259.5 ind./L in spring. Annual average biomasses of protozoa, rotifera, cladocera and copepods were 0.13 mg/L, 0.11 ...

...a viz.; copepoda, rotifera and cladocera. The diversity of the zooplankton species in the lake was determined by richness and evenness indices, which were found as follows; Margalef Index 1.30 to 3.87, Shannon’s Index 2.54 to 3.68, Simpson Index 0.92 to 0.97, Simpson’s Reciprocal Index 12.25 to 37.69 and Pielou’s Evenness Index 0.94 to 1.0. The zooplankton community was found abundant in summer as compared to winter. The copepods were ...

...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 ...

...e population dynamics of rotifers at specific sites of Khanki Headworks, District Gujranwala, Punjab, Pakistan from February 2021 to January 2022. During this time period, 34 species of rotifers belonging to 10 families and 12 different genera were identified. Brachionidae was proved to be the most abundant family followed by Asplanchnidae. Population density was maximum in June and lowest in January. <...

...n vivo on the species of rotifers Brachionus plicatilis. We analysed the relationship between the ratio of photoluminescence (PL) intensities (I585/I480) and MeHg concentration (CMeHg) to create a master curve for calculating MeHg concentration based on the measurement of PL intensities. Quantitative results showed that the bioaccumulation of MeHg in the rotifers increased from 1.65 μg at 30 min to 2.33 μg at 180 min a...
