Mat thickness associated with and spp. in the southern rivers of Chile.

is a diatom that can alter aquatic systems. Several investigations have shown as chemical, and hydraulic factors have a great influence on the proliferation of , 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 mat thickness, and another taxon that produces mucilage, , while also considering physical and chemical factors.
