Diversity of the Passiflora L. in the Serra do Mar ecoregion and the relationships with environmental gradients, South and Southeast, Brazil

The species of the Passiflora (Passifloraceae s.s.) are distributed in tropical and subtropical regions great ecological importance. Serra do Mar is formed large escarpments along Brazil’s east coast, between States Rio de Janeiro Grande Sul. This study aims to point out occurrences herbaria Mar, addition evaluating conditions each specimen found. richness sample effort maps were prepared establish locations where greatest numbers records encountered. We evaluated relationship distribution through Canonical Correlation (CCA) Quadratic Polynomial Analysis. also floristic composition using a cluster analysis. Calculations Extent Occurrence (EOO) Area Occupancy (AOO) performed for endemic Atlantic Forest area occurring Mar. A total 53 species, belonging found São Paulo ones that recorded collection effort. climatic variables Precipitation Driest Quarter Annual Average Temperature most correlated area. Twenty-two area, 21 as having some degree threat on Official Lists. In this study, we present all including those endemics Forest, demonstrates importance conservation.
