Resumo No estado do Ceará, as principais áreas amostradas com relação às briófitas são constituídas de encraves úmidos e subúmidos, remanescentes da Mata Atlântica. Estudos em áreas de Caatinga são praticamente inexistentes. O presente trabalho objetivou realizar um inventário florístico das briófitas da Chapada do Apodi, dentro dos limites do território do estado do Ceará, uma região com predominância do Domínio Caatinga. As coletas fizeram parte das atividades de campo do Programa de Pesquisa em Biodiversidade do Semiárido (PPBio). O material briológico foi coletado em 2014, na área da Chapada do Apodi localizada dentro do território do estado do Ceará. Foram encontradas 59 espécies de briófitas sendo 27 hepáticas - Marchantiophyta - distribuídas em sete famílias e 11 gêneros e 32 espécies de musgos - Bryophyta - distribuídas em 14 famílias e 26 gêneros. Das espécies encontradas, 25 se configuram como novos registros para o estado do Ceará e Riccia subplana está sendo citada pela primeira vez para a Região Nordeste. Estão sendo acrescentados ainda 23 novas ocorrências para a Caatinga. São fornecidos comentários taxonômicos para as novas ocorrências para o estado do Ceará e para a Caatinga. A espécie Weisiopsis bahiensis é ilustrada.

Abstract In the state of Ceará, bryophytes have been mainly sampled in humid and sub-humid enclaves, remnants of Atlantic rain forest, while studies in the Caatinga Domain are practically non-existent. The present work aimed to survey the floristic composition of bryophytes of the Apodi Plateau, a region predominantly covered by Caatinga. Collections were conducted as part of the field activities of the Program for Research in the Biodiversity of the Semiarid region of Brazil (PPBio). The briological material was collected in 2014, in the Apodi Plateau located within the territory of Ceará state. Fifty-nine bryophyte species were found: 27 liverworts - Marchantiophyta - distributed in seven families and 11 genera, and 32 mosses - Bryophyta - distributed in 14 families and 26 genera. Among the species found, 25 were new records for the state of Ceará and Riccia subplana is reported for the first time for the Northeast region of Brazil. Twenty-three are new records for the Caatinga Domain. Taxonomic comments are provided for the new records for the state of Ceará and for Caatinga, as well as an illustration of the species Weisiopsis bahiensis.

ABSTRACT Campos rupestres (rupestrian grasslands) are characterized by the presence of rock outcrops associated with an herbaceous-shrub physiognomy typically growing on quartzitic soils; they occur a wide variety of habitats. Bryophytes respond rapidly and efficiently to variation in microclimate. The present work aimed to study bryophyte species richness, diversity and composition, their life forms, and the substrates they colonize in exposed and shaded habitats in campos rupestres of Chapada Diamantina. Collections were made in 25 x 25 m sampling plots. One hundred and nine species were recorded and included a predominance of mosses (78 spp.) over liverworts (31 spp.). Most species (79 %) were restricted to one of the two types of habitat (exposed versus shaded). While the genera Campylopus, Polytrichum, Schlotheimia, Macromitrium and Syrrhopodon were prevalent in exposed habitats, Sphagnum, Lepidozia, Micropterygium, Bazzania and Odontoschisma prevailed in shaded habitats. The rupicolous community was more prominent than the other communities in both types of habitat. “Weft” was the most frequent life form in shaded areas, while “turf” predominated in exposed sites. The high number of rare, and exclusive, species illustrates the high degree of heterogeneity among bryophyte communities in campos rupestres, and demonstrates the importance of habitat heterogeneity for the high diversity.

Bryophytes constitute an important component of tropical rain forests, which provide microhabitats favorable for their establishment. Bryophytes are also quite responsive to changes in microclimate, which makes them good bioindicators. This study aimed to determine the diversity and distribution of bryophytes in upper and lower montane forests of the Chapada Diamantina region of the state of Bahia, Brazil. To that end, we studied community aspects such as richness, diversity, substrates colonized, life forms and floristic similarity between areas and regions. In 2007 and 2008, we collected specimens from six forest sites, located from the north to the south of the Chapada Diamantina region. We identified a total of 205 infrageneric taxa. In comparison with the lower montane forests, the upper montane forests presented higher diversity and species richness, as well as greater numbers of substrates colonized, life form types, species of restricted geographic distribution and species typical of shaded areas. We also found low similarity in the species composition, the populations of the upper and lower montane forests forming two large and distinct groups. Although presenting relatively high floristic homogeneity among themselves, the Chapada Diamantina areas presented little similarity with those of the Atlantic Forest. This can be explained by the differences between the two regions in terms of environmental conditions, precipitation, seasonality, elevation and continentality.

The Chapada Diamantina ecoregion is within the caatinga (shrublands) biome of Brazil. Environmental factors determine the phytophysiognomies that distinguish the ecoregion from the surrounding areas. This study aimed to investigate the distribution of bryophyte flora in this ecoregion, by phytophysiognomy and elevational zone. Analyzing specimens we collected from five municipalities in the region, together with specimens (previously collected from the region) in herbaria, we identified 400 taxa. The phytophysiognomies that presented the highest species richness and the greatest numbers of exclusive taxa were forests and campos rupestres (dry, rocky grasslands), which respectively accounted for 51% and 40% of the taxa, compared with only 5% and 4%, respectively, for the caatinga and cerrado (savanna). Species richness and the numbers of exclusive taxa were highest in the lower and upper montane zones. There was a predominance of neotropical taxa and a significant number of disjunct species found in Brazil and in the Andes region. We conclude that the Chapada Diamantina region is an important center of bryophyte diversity, harboring not only a great number of species overall but also a considerable number of species exclusive to the region, primarily in forests and campos rupestres at elevations above 800 m.
