Diversidade florística em três unidades de conservação do município de Nova Tebas - Paraná

Abstract

This study registered 375 species for the total vascular flora, distributed among 89 families and 276 genera, in which 4 (four) families had the highest number of species: Asteraceae, Fabaceae, Solanaceae and Piperaceae. The predominant way of life is herbs, followed by shrubs, subshrubs, vines and trees. For the use of substrate, there was a predominance of terrestrial species, followed by rupicolous, epiphytes, aquatic and hemiparasites. As for the dispersion syndrome, zoochory was predominant, then anemochory, autochory, barochory, and no hydrochory species occurred. Until the present moment, 9 (nine) species are endangered in Paraná and 1 (one) in Brazil. Regarding exotic species, 13 species were identified as exotic, among them 8 (eight) are considered invasive exotics in the state of Paraná. The floristic similarity analysis resulted in a listing with 1,245 species, in 6 (six) study areas, and the clusters formed indicate a greater influence of the Semideciduous Seasonal Forest on the floristic composition.
