Classificação de briófitas bioindicadoras de qualidade ambiental da área conhecida como areal no município de Parintins AM

Abstract

Briofits are plants of tiny size, considered the simplest of the vegetable kingdom for they possess not conductive vases of sap (xilema and floema). Saint of extreme ecological importance because they participate in the maintenance of the ecosystem, mainly of the processes of ecological succession, being them, pioneering. The present work looked for to classify briófitas bioindicadoras starting from the rising of species in the area of the Sand dune in the municipal district of Parintins/AM, analyzing the briofits presence for substratum and identifying them taxonomicamente. They were collected and identified in the total 44 briófitas samples, which are distributed in the following families: Calymperacea, Leucobryaceae and Sematophylacea (Class of the mosses) and Lejeuneaceae and Radulaceae (Class of the liverworts), however, among the collected individuals, the largest occurrence was of the species Octoblepharum albidum Hedw., belonging the family of Calymperaceae. The plants were found colonizing different substrata, as: trunks, branches and alive branches of trees (corticícolo) or dead (epíxilo) and leaves (epífilo), besides soils (terrícolos), and the largest occurrence of collected briófitas was in the substratum corticícolo.
