Levantamento de espécies trepadeiras na Estação Ecológica Municipal Reinaldo Petrechen em Nova Tebas – PR

Abstract

The floristic and phytosociological knowledge and study of plant interactions with animals are key to understanding the structure and dynamics of communities and their regeneration process. In order to characterize the floristic composition of creepers, it performed a study of these species in the Municipal Ecological Station Reinaldo Petrechen, which has approximately 261 ha and is located in the municipality of Nova Tebas, Paraná. Samples were collected monthly over a period of 10 months from August 2015 to June 2016. The vines were classified as to their ways to scale and their dispersal syndromes. They found 46 species belonging to 23 families, especially Fabaceae one facing a very high risk of extinction in the state, demonstrating a significant importance of the Ecological Station for biodiversity in the state of Paraná. In terms of wealth, families most representative were Fabaceae and Bignoniaceae, Sapindaceae, followed by Convolvulaceae, Cucurbitaceae and Malpighiaceae. Together, these six families account for approximately 59% of the species of vines found in the Ecological Station. It was found that no pronounced predominance of the species, resulting in scandent and prehensile, followed by switchers. As the dispersion syndrome, there was a predominance of anemochory in which the species disperse their diasporas through wind action, followed by autochory, zoochory and a species was not classified. Despite the short sample period of time amounting to less than a biological year, so it can be assumed that the fragment in question has a greater diversity than ever found in the Conservation Unit.
