Periphytic algae of two bioforms of macrophytes in a subtropical shallow lake of Argentina

The aim of this study was to analyse the structure and temporal variations in density and diversity of periphytic algae from Potamogeton illinoensis Morong (submerged and perennial macrophyte) and Nymphoides indica (Linné) Kuntze (rooted fl oating leaves and seasonal growth). The study was conducted...

The study was conducted in a shallow lake in northeastern Argentina (27° 29’ S; 58° 45’ W), between March 2007 and February 2010. Sixty-one taxa were exclusive to P. illinoensis, 12 were exclusive to N. indica, and 54 were common to both. Density, number of species and diversity were comparatively higher in P. illinoensis than in N. indica. Cyanobacteria (mainly Stigonema hormoides Bornet & Flahault) were dominant in P. illinoensis, whereas Chlorophyta (Oedogonium spp.) were dominant in N. indica. Potamogeton illinoensis developed a stable, mature epiphytic community over time. In N. indica, the density and diversity of periphytic algae were related to the plant seasonality and water level fl uctuations. Algas perifíticas de duas bioformas de macrófitas em um lago raso subtropical da Argentina. O objetivo deste estudo foi analisar a estrutura e as variações temporais de densidade e diversidade de algas perifíticas de Potamogeton illinoensis Morong (macrófi ta submersa e perene) e Nymphoides indica (Linné) Kuntze (enraizada com folhas fl utuantes e crescimento sazonal). O estudo foi realizado em um lago raso do nordeste da Argentina (27° 29’ S; 58° 45’ W), entre março de 2007 e fevereiro de 2010. Sessenta e um táxons foram exclusivos para P. illinoensis, 12 exclusivos para N. indica e 54 foram comuns a ambas as formas de macrófi tas. A abundância, número de espécies e diversidade foram comparativamente maior em P. illinoensis que em N. indica. Cyanobacteria (principalmente Stigonema hormoides Bornet & Flahault) dominaram em P. illinoensis, enquanto Chlorophyta (Oedogonium spp.) fez em N. indica. Potamogeton illinoensis desenvolveu uma comunidade epífi ta estável, madura ao longo do tempo. Em N. indica a densidade e diversidade de algas perifíticas foram relacionados pela sazonalidade da planta e as fl utuações do nível de água. 2021-08-26T13:44:26Z 2021-08-26T13:44:26Z 2015-08-15 Artículo Vallejos, Silvina Vanesa, Zalocar de Domitrovic, Yolanda y Martínez, María Soledad, 2015.
