Implication

Limnological survey identifies 22 smooth-walled Cosmarium taxa across varying iron and pH conditions in riverine periphyton, highlighting high microscopic algal diversity post-disaster.

Key Points

Identify and document smooth or finely punctate cell-walled Cosmarium species in the lower Doce River basin and assess the environmental conditions in which they occur.
Collected monthly periphytic samples from October 2018 through February 2020 (omitting October 2019) in the lower Doce River region, Espírito Santo State, Brazil.
Measured environmental parameters, including trophic state, pH, and total iron concentrations, associated with the occurrence of each identified taxon.
Identified 22 taxa belonging to smooth or finely punctate cell-walled Cosmarium species.
Documented 21 new records for Espírito Santo State and one new record (Cosmarium trilobulatum var. tumidum) for Brazil.
