1. Bryophyte flora of the Apodi Plateau, Ceará, Brazil
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 d

2. Briófitas do Parque Estadual de Campos do Jordão, Estado de São Paulo, Brasil
RESUMO Parque Estadual de Campos do Jordão é uma importante área remanescente da Mata Atlântica e não apresenta levantamentos brioflorísticos. O objetivo deste estudo foi realizar o levantamento da flora de briófitas do PECJParque e, desta forma, fornecer dados sobre a diversidade desse grupo vegetalina área, destacando aquelas espécies que represen

3. The chloroplast genome of the desiccation-tolerant moss Pseudocrossidium replicatum (Taylor) R.H. Zander
Abstract Mosses in conjunction with hornworts and liverworts are collectively referred to as bryophytes. These seedless, nonvascular plants are the closest extant relatives of early terrestrial plants and their study is essential to understand the evolutionary first steps of land plants. Here we report the complete chloroplast (cp) genome sequence of Pseudoc

4. New records for the bryophyte flora of the Brazilian Amazon
Resumo Excursões botânicas recentes no norte do Brasil resultaram em 38 registros novos para estados brasileiros e o país. Resumido, sete (cinco hepáticas e dois musgos) espécies são novos registros para o Brasil, 18 sendo novos registros para o estado do Amazonas (10 hepáticas e oito musgos) e 20 para o estado de Roraima (16 hepáticas e quatro musgo

5. Spores of Plagiochila (Dumort.) Dumort.: the taxonomic relevance of morphology and ultrastructure
ABSTRACT Plagiochilaceae is a family of leafy liverworts that are distributed worldwide. It is of great importance due to its taxonomic and ecological implications among bryophytes. Most species of the family belong to the genus Plagiochila, but there is no consensus regarding its infrageneric circumscription. There have been few palynological studies involv

6. Habitat heterogeneity and diversity of bryophytes in campos rupestres
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,

7. Survey of bryophytes in Serra da Canastra National Park, Minas Gerais, Brazil
ABSTRACT Serra da Canastra National Park is located in southwestern Minas Gerais State and contains several phytophysiognomies of the Brazilian Cerrado. To date, no study on bryophytes has been conducted in this area and the present study is the first to be carried out in this major biological reserve of Cerrado located on the Brazilian Plateau. This study f

8. 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 northeas

9. Bryophyte flora in upland forests at different successional stages and in the various strata of host trees in northeastern Pará, Brazil
In the northeastern region of the Brazilian state of Pará, approximately 90% of the forested areas are secondary forests. Secondary forests are interesting areas for floristic studies aimed at determining the effects that clear-cutting has on bryophyte communities. The aim of this study was to compare upland forests at different successional stages and the

10. Bryophytes on rocky outcrops in the caatinga biome: a conservationist perspective
In the state of Paraíba, Brazil, there is an abundance of rocky outcrops, which are typical elements of the semi-arid landscape. Those outcrops provide refuge to species with morphological adaptations to stressful climates and to rare communities of plants, including bryophytes. Nevertheless, there have been no studies of bryophytes in such habitats in the

11. New records of bryophytes for the state of Rio Grande do Sul, Brazil
The aim of this study was to complete the species list and disseminate data regarding the diversity of bryophytes in the state of Rio Grande do Sul, Brazil. We registered 51 species of bryophytes (11 mosses and 40 liverworts) as new records for Rio Grande do Sul, of which six represent the second records for Brazil.

12. Bryoflora of the municipalities of Soure and Cachoeira do Arari, on Marajó Island, in the state of Pará, Brazil
This study aims to investigate the richness and ecological aspects (ecosystem and substrate) of mosses and liverworts at two municipalities on Marajó Island, in the state of Pará, Brazil. The study area (6615 km²) encompasses the municipalities of Soure and Cachoeira do Arari. Bryophytes were collected from the 10th to the 16th of January, 2007, during ra
