The N: P: Si Stoichiometry and Relative Abundance of Diatoms in Ganga River

Jitendra Pandey, Amita Yadav & Rachna Singh · Current Journal of Applied Science and Technology · 2015

In order to assess the changing pattern of N: P: Si stoichiometry and associated shift in the abundance of diatoms, we analysed DO, BOD, NO3-, PO43-, DOC and DSi in a 37 km long stretch of Ganga River. The N: P stoichiometry declined (from 13.6 to 5.3) at downstream sites receivi...
