Composição florística e estrutura da comunidade de trepadeiras da Floresta Atlântica no Sul de Santa Catarina, Brasil

Abstract

Climbers are important for the composition and structure of tropical and subtropical forests. This study aimed to analyze the floristic and community structure survey of climbers in the Parque Estadual da Serra Furada, in southern Santa Catarina, Brazil. The fl oristic survey was carried out in disturbed areas by the walking method, and the structural survey was conducted in inland areas of the forest. Seventy species of climbers were recorded, 44 were woody and 26 were herbaceous. The most representative families were Asteraceae (14), Bignoniaceae (12) and Apocynaceae (eight). Anemochory was the most common dispersion strategy. Mickelia scandens (Raddi) R.C. Moran was the most abundant species and had the highest Importance Value Index. Voluble was the climbing mechanism most found, while radicant was most abundant. This study contributes to the knowledge of vine fl ora from southern Brazil, including herbaceous climbers, rarely included in quantitative studies of this plant group.
