✦ Synopsis
Defensive reactions of rhithron and epipotamon against low and early organic pollution are described. Hitherto two reactions could be found in streams: transformation of the epilithic energy flow to intensify microbial decomposition, and the mass production of Cludopliorci for elimination OF biomass, nutrients, heavy metals and other noxious agents. The Clndopkorcl production reaction leads to a centralization of the ecosystem, but functions incompletely. This can be compensated by an KO- system-adequate restoration method. Similarly the "whiting" (i.e. biogenic decalcification) during in pelagials Cladophorn mass production happens at the expense of the benthic communities and may be called "dysoecism".
