Epífitas vasculares do Parque Natural Municipal Curió, Paracambi, RJ: riqueza, composição de espécies, conservação e relação com outras localidades

Abstract

Epiphytes are plants that grow on other plants without causing damage to your hosts. These vegetables have attracted interest because of their wealth, mainly in tropical and subtropical forests. This study is focused on this important group of plants. The work is divided into three chapters and has as general objectives: introduce a scientometric review and analysis of vascular epiphytes in Atlantic Forest; gather information on the vascular epiphytes flora of the Parque Natural Municipal Curió Paracambi and evaluating the influence of the characteristics of phorophytes on the distribution of vascular epiphytes. On the first chapter introduce an analysis of studies published between 1990 and 2015 showing the increase in production on the subject, but still slowly with concentrated studies in areas of the South and Southeast of Brazil. The category of articles is the most important in terms of production. In the second chapter the results showed the log of 43 species of vascular epiphytes distributed in 25 genera and 12 families, of which Polypodiaceae (10 ssp), Bromeliaceae (10 ssp) and Araceae (10 ssp) are the richest. The epiphytic flora similarity of the unit is very low compared to other studies developed in the same plant training areas. Half of the species is holoepífita dispersion characteristic and prevalent syndrome was zoochory. Regarding the risk of extinction of any species recorded included the National Official Species of Flora Endangered (Portaria no. 443 de 17/12/2014). For the third chapter it was observed that the different categories of cortical morphology were not associated with the colonization of phorophytes by vascular epiphytes.As for the correlation between dendrometric parameters of tree species with and without vascular epiphytes it found that those directly correlated to the presence of epiphytes were: total height, DAP and the depth of the crown and the surface of the shaft inverse correlation to the presence vascular epiphytes.
