Abstract: foram feitas para cada característica morfométrica utilizada na análise taxonômica (Necchi Junior et al. 2001). A identificação específica baseou-se na observação de estruturas sexuais amplamente descritas na literatura especializada (Christensen 1969, Blum 1972, Rieth 1980, Entwisle 1988, Sarma & Rattan 1990). Na ausência de estruturas reprodutivas, não foi possível proceder a identificação específica e, assim, tais populações foram referidas como coletivas (spp). Para cada táxon identificado foram apresentad… Show more

“…Our results differ from those reported by Necchi Júnior (), who considered Vaucheria as intermediate in terms of light adaptation; however, they are in line with some ecological studies on tropical Vaucheria (e.g. Branco & Necchi Júnior, ; Tonetto, Peres, & Branco, ), which have reported a trend for occurrence in shaded or heavily shaded streams.…”

“…However, the current velocity preferred by algae of this genus varies according to species and populations (Necchi, 1997). Likewise, Vaucheria may be considered inhabitant of slow-moving streams in some studies (Tonetto et al, 2012), but fast stream dwellers in others. For instance, V. sessilis is able to adhere at the subsoil in fast flow streams, while V. debaryana is detected in low current habitats and stagnant waters (Schagerl & Kerschbaumer, 2009).…”
