| Descrição: | Introduction: Tropical montane forests are characterized by high species richness and endemism of bryophytes. However, this diversity is highly sensitive to microclimatic changes related to anthropogenic disturbance. Objective: In this study, we assessed the richness and composition of epiphytic bryophytes on the trunks of trees in undisturbed and disturbed montane forests on the Western slope of the Baru Volcano National Park. Methods: Undisturbed forests were highly humid, while disturbed forests showed high light levels and temperature. In each tree we measured the presence and cover of epiphytic bryophytes in 160 quadrants of 20 × 30 cm. Results: In total, we recorded 86 species (49 liverworts and 37 mosses). Bryophytes richness was positively influenced by disturbance, with disturbed forests showing a high number of sun epiphytes. Bryophyte community composition was different in each forest type, with shade epiphytes confined to primary forests and sun epiphytes restricted to disturbed sites. Conclusions: Bryophyte communities were effective indicators of montane forests disturbance on the Baru Volcano. Thus, protection of the undisturbed forests remnants might help to preserve a rich and diverse community of epiphytic bryophytes. |
