...y of the Nile River. Meroplanktonic larvae were the major component representing 39.4% of the total zooplankton abundance. Copepods and their larval stages contributed 36.2%. Rotifers ranked the third important group (12.6%). Protozoa contributed 10.6% of the total community. According to the Canonical Correspondence Analysis (CCA), the variations in the species data were significantly (P< 0.05) related to salinity, temperature, phosphate concentration and ...

...ia promoting or limiting planktonic larval dispersal. The clam, Meretrix meretrix, is an important aquaculture species in the coastal regions of China. However, the previous studies of genetic information about M. meretrix were vague. None integrated research to reveal the population genetic and structure of M. meretrix in China from north to south. In this study, we investigated the genetic variation of seven location samples distributing...

... significantly increased planktonic cells (after 3 days) and increased loosely bound cells (after 5 days). Similarly, air liquid interface coverslip indicated significant increase in biofilm after 1 day. Comparison of antibiofilm effect using proteolytic enzymes indicated that although all enzymes resulted in significant decrease (p<0.05) in biofilm formation after 1 hour, however, inhibitory effect of proteinase k was more pronounced (p<0.001; 80%) comp...

... 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 densi...

... T. clavigera has a long planktonic larval period (i.e., ~ two months). In order to identify the relevant factors affecting the genetic structure of T. clavigera, a total of 147 T. clavigera individuals distributed along the Chinese coast from 9 populations were analysed genetically on the bases of cytochrome oxidase I (COI) gene. Analysis of the COI genetics indicated a high level of genetic diversity among T. clavigera. Our analysis of population genetic and...
