Biodiversity survey, ecology and new distribution records of Marchantiophyta in a remnant of Brazilian Atlantic Forest

We present the results of a survey of the liverwort species occurring in a fragment of dense montane ombrophilous forest in Parque Nacional de Boa Nova, located in a transition zone between Caatinga and Atlantic Forest in southwestern Bahia State, Brazil. A total of 126 species distributed among 41 genera and 14 families were found. Sixteen species are reported for the fi rst time from the state of Bahia, while ten species represent new records for the Northeast Region of Brazil. The family Acrobolbaceae E.A. Hodgs and the genus Dicranolejeunea (Spruce) Schiff n. are also reported for the fi rst time from Bahia. Cololejeunea winkleri (Morales & Benecker) Bernecker & Pcs, is cited for the fi rst time from the Brazilian Atlantic Forest. The results obtained in this study demonstrate the importance of Parque Nacional de Boa Nova for the conservation of bryophyte biodiversity in Brazil.
