Potamoplankton
potamoplankton
[¦päd·ə·mō¦plaŋk·tən]Potamoplankton
the passively floating plant and animal life in rivers and other freshwaters with a current. Potamoplankton consists predominantly of diatomaceous algae, rotiferans and water fleas. It results basically from the drifting of planktonic organisms into the river from lakes, swamps, and river backwaters. The pollution of the rivers by industrial and other wastes has a strong influence on the composition and abundance of the plankton.
