Descripción
Vegetation associated to the Paraná River is subject to conditions imposed by the pulse regime. This study aimed to evaluate the pulse regime influence on the vegetation of the Paraná River islands. Using multivariate techniques for classification and ordination, six communities were identified and described: willow forests of marginal levees, riverine forest of internal levees, floating meadows, floating rooted plants, a tall grass herbaceous community and a marshy community. The forests were the most diverse and the richest communities while the floating meadows and the marshy community were less rich and diverse. Our results indicate that duration and recurrence of floods are important variables in determining the characteristics of the vegetation. However, forests with a similar flood recurrence and duration showed important differences in physiognomy, structure and floristic composition. The differences between the forests could be explained by the connectivity degree, geomorphological dynamics and succession time.
A vegetação associada ao rio Paraná está sujeita ao regime do pulso. O objetivo deste estudo é avaliar como o pulso influencia a vegetação em ilhas do rio Paraná. Após aplicação de técnicas multivariadas, seis comunidades foram identificadas e descritas: mata de salgueiro de diques marginais, mata ciliar de diques internos, vegetação aquática flutuante, comunidade aquática arraigada, comunidade herbáceas de grama alta e comunidade pantanosa. As matas foram os mais diversos e o mais rico entre as comunidades. Entretanto, as vegetações flutuantes e pantanosas foram menos ricas e diversas. Nossos resultados indicam que o tempo e periodicidade das inundações é uma variável importante para determinar as características da vegetação. No entanto, a mata, com semelhantes periodicidade e duração de inundações mostrou diferenças na fisionomia, estrutura e composição florística
