phytoplankton communities play a significant role in the oceanic biological pump by forming the base of the trophic structure. increase in nutrients loading affects spatial and temporal distribution of phytoplankton. this study examined the phytoplankton community structure and ecological indices in relation to nutrients dynamics in both estuarine and oceanic areas of ramisi-vanga systems along...

the zerebar lake is a shallow freshwater lake located in the northwestern iran. the lake is surrounded by three human activities: agriculture, tourism and dam. the present study aimed to investigate (1) which human activity has the greatest impact on eutrophication of the zerebar lake (2) if phytoplankton communities, as the indicator, are correlated with the human activities. water samples wer...

Herein, we report the response of indices based on phytoplankton and zooplankton and their combination to different nutrient concentrations in lakes. The study was carried out in ten lakes in northeastern Poland. Integrated samples were collected from the epilimnion during the summer of 2012-2013. Secchi disk visibility (SD), total phosphorus (TP), total nitrogen (TN), and chlorophyll a were us...

The study of spatial and temporal variability of distribution of phytoplankton communities in Northern part of the Persian Gulf (Qeshm andLengeh Islands) was studied. In this study, five groups (47 genera) of phytoplankton include Bacillariophyceae, Dinophyceae, Cyanophyceae, Crysophyceae and Euglenophyceae were identified. The results showed that Diatoms group (79.6 %) and Rhizosolenia genus (...
