Levantamento da flora de Pteridophyta em um fragmento de floresta estacional semidecidual em Fênix Paraná, Brasil

Abstract

The present work deals about the floristic survey of the species of Pteridophyta of RPPN Agro Mercantil Vila Rica Ltda. This RPPN located in the city of Fênix in the State of Paraná, Brazil and aimed to survey the flora of Pteridophyta and their different habitus. For the collect of the material shipments on a weekly basis for a period of three months and were recorded in the study area Pteridophyta of 14 species, distributed in 12 genera and eight families were conducted. Among the species found in the study area, three families make up more than 70% of the diversity of the local of Pteridophyta: Pteridaceae, Polypodiaceae and Dryopteridaceae. The most common habit among the terrestrial species collected was 72%. There was no correlation between the relative humidity and temperature with diversity. Studies are needed to prove or refute the relationship between soils and diversity of Pteridophyta. It is recommended to continue the work, considering that the sampling effort was not adequate.
