Abstract

The riparian forest sustains an expressive richness and diversity of species and anthropogenic impacts
in certain sites have caused changes in the structure of the communities. This study aimed to analyze the
composition and structural parameters of the lichen community in riparian forests. The study was carried out
in seven sites surrounded by different matrices: rural, urban and industrial. The lichens were mapped using the
acetate method and the composition and phytosociological parameters were analyzed. A total of 208 species
were identified. The riparian forest sites of the rural matrix differed from the others by the dominance of the
morphological forms crustose and squamulose, as well as the predominance of species from humid and shaded
environments. Phyllopsora lividocarpa, Phyllopsora parvifolia and Herpothallon minimum presented the
highest importance values in the forest sites. The lichen community presented greater homogeneity in riparian
forest sites of the urban-industrial matrix. Modifications in the species’ composition and structural parameters
of the lichen community demonstrated a gradient of disturbances in the different matrices. Preservation actions
of riparian forests are essential for the conservation of the species and landscape connectivity since they act
as an important reservoir of biodiversity in sites of subtropical watersheds.

Key words: Atlantic Forest, lichenized fungi, rare species, urbanization

Resumo

As florestas ripárias sustentam expressiva riqueza e diversidade de espécies e os impactos antropogênicos
em determinados locais podem ocasionar modificações na estrutura das comunidades. O objetivo do estudo
foi analisar a composição e parâmetros estruturais da comunidade liquênica em florestas ripárias. O estudo
foi realizado em sete áreas inseridas em diferentes matrizes: rural, urbana e industrial. Os liquens foram
mapeados utilizando o método do acetato e foram analisadas a composição e os parâmetros fitossociológicos.
Um total de 208 espécies foram identificadas. As áreas florestais da matriz rural diferiram das outras pela
dominância das formas morfológicas crostosas e esquamulosas, assim como pela predominância de espécies
de ambientes úmidos e sombreados. Phyllopsora lividocarpa, Phyllopsora parvifolia e Herpothallon minimum
apresentaram os maiores valores de importância nas áreas florestais. As modificações na composição de
espécies e nos parâmetros estruturais demonstraram um gradiente de perturbação nas diferentes matrizes.
Ações de preservação nas áreas florestais ripárias são essenciais para a conservação das espécies e
conectividade da paisagem uma vez que atuam como importante reservatório de biodiversidade em áreas
de bacias hidrográficas subtropicais.
