Comparação da assembléia de trepadeiras em dois fragmentos florestais do centro-oeste paranaense

Abstract

This study aimed to survey the flora of vines two forest fragments located in the central-western Parana, namely the Parque Estadual Lago Azul (PELA) and the Estação Ecológica Municipal Luiziana (Es.Ec.ML), the characterization of the syndromes pollination and dispersal, habit and way of ascent, as well as the comparison of the results obtained. The samples in Es.Ec.M.L.. conducted in the period of August 2010 to July 2012, with weekly samples. The occurrence of species in the PELA based on consultations with the acquis Herbarium HCF, which has records of previous collections, for the period from March 2006 to March 2009. The pollination and dispersal syndromes in the same way that the classification of habit and mode of ascent followed those of field observation, consultation records present in the Herbarium HCF, morphological analysis (flower, fruit and seed) and literature review. This finding study was conducted to compare the fragments studied since they are under similar climatic and ecological characteristics, and contribute to the understanding of this group of plants. Were recorded in PELA 80 species of vines and in the Es.Ec.ML. were 70, distributed respectively on 26 and 30 botanical families. The richest families were registered Apocynaceae (11), Bignoniaceae (11),Malpighiaceae (seven) and Passifloraceae (eight), the BY and Apocynaceae (eight), Bignoniaceae (eight), Fabaceae (six) and Sapindaceae (seven) in Es . Ec.ML where these represented the end of the survey 44% of the recorded species. Regarding dispersal syndromes, the most frequent in the two fragments was anemochory, representing 52% of all species recorded in this study. The pollination syndromes more frequently in the two fragments were melittophily and ambofilia of melittophily / myiophily, each corresponding to 31% of species. The herbaceous habit prevailed in two fragments, representing altogether 60% of the recorded species, as compared to the rise of so fickle vines were most frequent, accounting for nearly 40% of the recorded species. On the assumption of the similarity between the fragments, only 21% of the species have common places, showing significant differences between them. This inequality can be associated with different factors, which often associate the peculiarities of the local.
