Podostemum rutifolium subsp. rutifolium como estruturador da comunidade de algas perifíticas em um rio neotropical

Abstract: Resumo As plantas da família Podostemaceae possuem caráter riacófilo, crescendo sobre substrato rochoso. O presente estudo foi desenvolvido no rio Paraná com o objetivo de registrar Podostemum rutifolium Warm. subsp. rutifolium e analisar a composição, a riqueza e a densidade da comunidade de algas perifíticas nesta macrófita. Para amostragem, foi utilizado um quadrado de borracha (25 cm2), mergulho em apnéia e a remoção da planta aderida à rocha. Posteriormente foi realizada a remoção, fixação, identificação … Show more

“…provides microhabitats for many algal species (mainly diatoms) and, therefore, is a key species in the structure of those communities. Aquatic plants are important structuring of algal communities and directly affect diversity and richness of the attached or associated microorganisms, especially in the lotic systems (Ferreira et al 2011).…”

“…These strategies include mucilaginous sheaths, stems for fixing to the substrate, excretory pores, and differentiated basal cells that facilitate adhesion to the substrate (Barsanti and Gualtieri, 2006). These characteristics promote efficient colonization and rapid growth in substrates and have been observed in other lentic environments (Stevenson, 1996;Vercellino and Bicudo, 2006;Felisberto and Rodrigues, 2010;Ferreira et al, 2011).…”
