Levantamento de espécies de epífitas na estação ecológica municipal Reinaldo Petrechen em Nova Tebas – PR

Abstract

The forest fragmentation is a serious consequence of actuality which creates a high level of disturbance and environmental degradation. In order to preserve, conserve and promote the biodiversity regeneration of these fragments, the Conservation Units were created. The Reinaldo Petrechen Municipal Ecological Station is a type of Protected area located in a transition zone between the Mixed Ombrophylous Forest and the Semidecidual Forest. Therefore, a floristic survey of epiphytic species located at the Reinaldo Petrechen Municipal Ecological Station was surveyed, with the purpose of raising the existence of epiphytes species in the Station to classify them as their dispersion syndromes and as epiphytic habit. There were 22 vascular epiphytes species distributed in seven families. The families that had the highest occurrence in the area were Orchidaceae, with seven species, followed by, Piperaceae, with six species and Polypodiaceae, with four species. The categorical relationship to the host revealed the predominance of true holoepífitos, which has 15 species (68,19%). Among the dispersion syndromes, anemocoria stands out with 8 representatives. Gomesa cruciata (Rchb.f.) M.W.Chase & N.H.Williams e Gomesa lietzei (Regel) M.W.Chase & N.H.Williams are species found in the present study that are considered respectively, rare and vulnerable, at Paraná state. Due to the fact that the area are secondary, the amount of epiphytes raised was not considered large, although, through the construction of rarefaction curves, it was possible to conclude that the sampling effort employed in the work was sufficient to compile a list of Epiphytes species occurring at the Reinaldo Petrechen Municipal Ecological Station.
