in this research, we investigated the cytotoxic mechanisms of cochlodinium polykrikoidescell lysate on isolated rat liver hepatocytes.this micro algae is responsible for a severe and widespread harmful algal bloom in the persian gulf and gulf of oman (2008-2009). isolated hepatocytes were obtained by collagenase perfusion of sprague-dawley rat liver.according to our results, incubation of algal...

In a monsoon-affected tropical estuary, oscillations in freshwater discharge during monsoon shifted the phytoplankton blooms from those adapted to low salinities to high salinities and vice versa. Salinity stratification during monsoon (onset and restart after an intermittent break) favored diatom (Skeletonema) bloom in low-saline surface waters. In high-saline, nutrient-rich bottom waters, Fra...

Sporadic algal bloom development within a IO year monitoring program in Virginia tidal tributaries of Chesapeake Bay is reviewed. These blooms were common events, characteristically producing a color signature to the surface water, typically short lived, occurring mainly from spring into autumn throughout different salinity regions of these rivers. and were produced primarily by dinoflagcilatcs...

Algae are sensitive to a wide range of pollutants, and are effective bioindicators in ecotoxicity assessments. Here, we evaluated the sub-lethal sensitivity of the marine dinoflagellate Cochlodinium polykrikoides upon exposure to copper (Cu), lead (Pb), bisphenol A (BPA), and Aroclor 1016 (polychlorinated biphenyl, PCB). Toxic effects were assessed by observations of the reduction in cell count...
