Mat thickness associated with Didymosphenia geminata and Cymbella sp. in the southern rivers of Chile

Abstract

Didymosphenia geminata is a diatom that can alter aquatic systems. According to the international literature, chemical and hydraulic factors have a greater influence on the proliferation of D. geminata, but the study of other microalgae that could be associated with it has been poorly addressed. The objective of this study is to evaluate the relationship between the structure of mat thickness D. geminata and another taxon that produces mucilage, Cymbella sp., while also considering physical and chemical factors.
