| temporal variation in density and diversity of cyanobacteria and cyanotoxins in lakes at nagpur (maharashtra state), india. | toxic cyanobacteria (tcb) are known worldwide for the adverse impacts on humans and animals. species composition and the seasonal variation of tcb in water bodies depend on interactions between physical and chemical factors. the present investigation delineates temporal variations in physico-chemical water quality parameters, viz. nutrients and density, diversity, and distribution of toxic cyanobacteria and cyanotoxins in lake ambazari (21 degrees 7'52''n, 79 degrees 2'22''e) and lake phutala (2 ... | 2010 | 19757108 |
