Two laboratory experiments were conducted to evaluate the amount of P utilization from two different types of sparingly soluble phosphate rock by aquatic biotic communities. The first type was Mussoorie Phosphate Rock or MPR (sedimentary in origin) and other was Purulia Phosphate Rock or PPR (igneous in origin). The two trials were with eight different treatment combinations. Among various trea...

In the present study, total thirty planktonic members from four sampling sites of selected research area in which, twelve phytoplanktons and eighteen zooplanktons each under different groups namely (Chlorophyceae, Bacillariophyceae, Cyanophyceae, Euglenophyceae) (Protozoans, Rotiferans, Cladocerans, Copepods) were recorded respectively. Among all phytoplanktonic groups, Chlorophyceae was domina...

in this study, the effect of some toxic organic chemicals on mogan lake has been investigatedusing the aquatox model. the unique property of the model includes the sub ecotoxicological modelwhen compared to the other water quality models. the ecosystem model aquatox, which is one of the fewgeneral ecological risk models that represents the combined environmental repercussions and effects of tox...

The concept of surrogates in biodiversity assessments has been widely accepted the recent years. Surrogates are taxonomic groups that indicate overall at a particular site. Zooplankton is an important component aquatic ecosystem, playing major role energy transfer between phytoplankton or producers and consumers higher trophic levels. In this study zooplanktons were considered as for biomonitor...
