Richness, abundance, and seasonality of macroalgal communities at different spatial scales in streams of the central-southern state region of Paraná State.
Keywords:
benthic algae, lotic ecosystem, seasonal variationAbstract
The structure and seasonality of benthic macroalgal communities of lotic ecosystems was evaluated at different spatial scales of observation in streams of the central-southern region of Paraná State. Samples were collected monthly from January to December 2007. We found 16 taxa (38% Cyanobacteria, 31% Chlorophyta, 19% Rhodophyta and 12% Heterokontophyta) without a confi rmed seasonality pattern.The fl oristic composition varied at all spatial scales corroborated by low values
