Fig. 1: Benthic cyanobacteria relations to flow in rivers.
From: A whole-ecosystem experiment reveals flow-induced shifts in a stream community
a Experimental flow manipulations in a free-flowing high-altitude stream reach, b using a series of v-notch weirs to reduce natural flow in fixed percentages, c showed an increase in benthic cyanobacteria levels, d worldwide studies (circles, n = 53) reporting qualitative observations of benthic cyanobacteria biomass decreases (yellow) and qualitative and quantitative observations of biomass increases (teal-blue) with respect to flow reduction. Right-downside frame show data reported for New Zealand.
