The study of climbing plants is still scarce in Brazil. Aiming to characterise the floristic composition of climbing plants, it was performed a research about climbing plants species at the Municipal Ecological Station Reinaldo Petrechen, which has approximately 300 ha and is located in Nova Tebas town, Paraná. The collection of plant samples were monthly, from August to October 2015. The climbing plants collected were classified according to their crawling way in: voluble, with tendril or scandent. Moreover, they were listed by their respective dispersion syndromes into Anemochory, Autochory and Zoochory. It was found 25 species, from 15 different families. In terms of richness of species, the families with more representativity were Bignoniaceae (five species) and Sapindaceae (four species), followed by Asteraceae, Convolvulaceae and Fabaceae with two species each. These families constitute 60% of climbing species present at the Ecological Station, demonstrating that the majority of climbing plant species found at the local pertain to few families, corroborating with other studies performed in different forestal fragments. It was verified the predominance of prehensile and voluble habits, both with 40%, followed by the scandent mechanism, with 20%. In relation with the dispersion syndromes, anemochory was predominant in the collection of plant samples performed, where 56% of species disperse its diaspores through the wind action, followed by autochory (32%) e zoochory (12%). The fact of this study being a preliminary one, it is implied that the results might change, being suggested the continuity of this research at the Municipal Ecological Station Reinaldo Petrechen. |
