Richness of Marchantiophyta and Bryophyta in a protected area of the Brazilian Amazon
The bryophytes of Gurupi Biological Reserve represent an important component of the biodiversity of the Amazon in the Brazilian state of Maranhão. This study aimed to investigate the richness of bryophytes (Marchantiophyta and Bryophyta) from Gurupi Biological Reserve and compare it with that found in other surveys conducted in Maranhão and in the northeastern part of the state of Pará, because the latter shows similarities with the study area in terms of vegetation, geography, demography, and history of occupation. We recorded 983 occurrences of bryophytes (549 Marchantiophyta and 434 Bryophyta) corresponding to 62 species (43 liverworts and 19 mosses), 39 genera, and 12 families. Of those 62 species, 25 have previously been collected from all regions of Brazil, two are restricted to two regions, and four are restricted to the northern (Amazon) region. The bryophyte species identified within the reserve correspond to 28.9% of the known bryophytes in Maranhão and 31.3% of the known bryophytes in northeastern Pará, the reserve therefore more closely resembling the latter area. The exclusively Amazonian elements found in the reserve underscore their affinity for this biome and their presence in the state of Maranhão. The importance of this conservation area to Maranhão and to the Amazon region of the state is confirmed by the high number of new records for the state (41 species), five of which are also new records for northeastern Brazil.
