Levantamento florístico expedito das espécies de trepadeiras na Estação Ecológica Municipal de Fênix, Paraná

Abstract

Knowledge of vines in Paraná State is still scarce. They are characteristic members of Semideciduous Forest, abundant and ecologically important, taking an active role in the dynamics of forest communities. This study aimed to survey the species of vines in Estação Ecológica Municipal de Fênix, as well as rating their dispersal syndromes and climbers habits. Weekly samples between December 2012 and February 2014 were made. The dispersal syndromes, the same way that the classification of the mode of ascent followed those of field observation, query the records present in the Herbarium HCF, morphological analysis (flower, fruit and seed) and literature review. Nineteen species of vines were recorded at Station, distributed in 14 botanical families, a smaller number of species in other works, explained by atypical year 2013, with strong frosts and high volume of rainfall, and for being a primary job. The richest families in terms of species were Bignoniaceae and Fabaceae with three species each, followed by two Cucurbitaceae species, which together make up a total of 42% of the wealth of the place. About dispersion syndrome, it has nine anemochoric, the most representative syndrome with 47,4%, followed six zoochoric species (31,6%) and four species autochorous (21%). The habit was the predominant climbing scandent (nine species), followed by prehensile (eight species) and switchers (two species). The Bignoniaceae and Cucurbitaceae families present exclusively prehensile species, Fabaceae presents only scandent species. It is strongly recommended to continue this work.
