Determinant factors for epiphyte-phorophyte interactions in patches of cloud forest within a matrix of campos rupestres [PDF]

Acta Botânica Brasílica
The epiphytic flora is influenced by the architecture and morpho-physiology of phorophytes. Our knowledge about the ecology of these communities remains limited, especially in the campos rupestres.
