Didymosphenia geminata, also known as “rock snot” and didymo, a freshwater, diatom algae is invading New Zealand and parts of the United States. Research findings on the effects of the algae on macroinvertebrate community structure, as well as the efficacy of releasing high flows from an irrigation storage dam to control the algae along a New Zealand stream were synthesized for publication.
