Diversidade e distribuição geográfica de angiospermas epífitas em áreas de ecótono de floresta ombrófila mista e estacional no Paraná, Brasil

Abstract

This study aimed to evaluate the diversity and distribution of epiphytic angiosperms in six Municipal Ecological Stations of Mato Rico and Nova Tebas, Paraná. Twentysix species were sampled in five families (Bromeliaceae, Cactaceae, Orchidaceae, Gesneriaceae and Piperaceae), with Orchidaceae being the most representative, with nine species. The six Ecological Stations have relatively low diversity, probably related to the degree of degradation of the areas. Altering the local microclimate can directly affect this group, due to its high vulnerability to environmental changes. The floristic similarity of the six study areas was evaluated along with 18 other areas of Mixed Ombrophylous Forest, Seasonal Semideciduous Forest and ecotone.
