Levantamento florístico de trepadeiras na estação ecológica municipal Colombo em Mato Rico – Paraná

Abstract

In Paraná there are few studies involving vines. The Colombo Municipal Ecological Station is a Conservation Unit belonging to the municipality of Mato Rico - PR, with an area of 318 ha. The aim of this study was the floristic survey of climbing species, together with the identification of their dispersal syndromes and climber habit, as well as collaborating with the knowledge of this community and subsidizing future works related to this way of life and area of growth. A study that has as a forest formation the Mixed Ombrophilous Forest (FOM). In order to collect the material, expeditions were carried out every two months on average, between August 2015 and May 2016. The classification of dispersion syndromes and climber habit, followed the methodologies of field observation, consultation and records present in the collection of the Herbarium HCF and support based on bibliographic review. Thirty - four species of vines were recorded, distributed in 22 botanical families. The most representative families were: Bignoniaceae (four), Curcubitaceae (three), Euphorbiaceae (three) and Passifloraceae (three). These four families represent 37% of the total recorded species. In relation to the dispersion syndromes, the anemocoria presents first with 14 species, followed by zoocoria with 12 species and finally, autocoria with eight species. Regarding the climber habit, the prehensile, voluble and scandante mechanisms presented homogeneity among themselves, showing little difference between the number of species, and preisseis presented with 13 species. Followed by fickle with 11 species, and scandal with 10 species. For Colombo Municipal Ecological Station, it is recommended to continue the floristic survey, since the unit has not been extensively explored, which demonstrates that other species can be approached with opening of more trails to be covered, and a larger area addressed.
