13. 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

14. Diversity of bryophytes in priority areas for conservation in the Atlantic forest of northeast Brazil
The northeastern Brazilian Atlantic forest is the region with the greatest diversity of bryophytes in the country. However, knowledge about bryophytes is irregularly distributed among Brazilian regions. Therefore, we aimed to contribute to knowledge about bryophytes on a regional scale in the northeastern Atlantic forest, to identify the centers of bryophyte

15. Survey of the bryophytes of a gallery forest in the National Park of Serra do Cipó, Minas Gerais, Brazil
Serra do Cipó has attracted the interest of many researchers over the years because of its unique characteristics, particularly the fact that the site represents the transition between Cerrado and Atlantic Forest. The study area of Serra do Cipó is located along a gallery forest "córrego Três Pontinhas," at 19°16'00" S and 43°32'49" W and an altitude o

16. Bryophytes diversity in Brazil
Resumo A brioflora do Brasil conta com 1.524 espécies, 117 famílias e 413 gêneros (11 antóceros, 633 hepáticas e 880 musgos). As famílias mais diversas de hepáticas são: Lejeuneaceae (285 espécies), Lepidoziaceae (48), Frullaniaceae (37), Ricciaceae (36), Plagiochilaceae (27), Radulaceae e Metzgeriaceae (26 cada), Lophocoleaceae (18), Aneuraceae (15

17. 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

18. Palynomorphs in Holocene sediments from a paleolagoon in the coastal plain of extreme southern Brazil
This paper presents the results of a qualitative palynological analysis of a 140 cm-thick section of Holocene sediments from a paleolagoon, representing the last 2600 years, taken from an outcrop at Hermenegildo Beach (33º42'S; 53º18'W), located in the municipality of Santa Vitória do Palmar, in the state of Rio Grande do Sul, Brazil. Samples were treated

19. 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

20. 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

21. Aquatic oligochaetes associated with bryophytes in an Atlantic Forest stream
Existem poucos registros na literatura sobre a colonização de macroinvertebrados bentônicos em briófitas. O presente estudo teve como objetivo analisar a fauna de oligoquetas em briófitas aderidas a pedras em um córrego de primeira ordem. As coletas foram realizadas em um fragmento de Mata Atlântica durante os períodos seco e chuvoso. Foram identific

22. 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.

23. Diversity and distribution of the bryophyte flora in montane forests in the Chapada Diamantina region of Brazil
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

24. Floristic overview of the epiphytic bryophytes of terra firme forests across the Amazon basin
Epiphytic bryophyte communities in terra firme forests of the Amazon region were investigated for the first time through standardized sampling across the Amazon basin. The sampling was carried out at nine localities, where bryophytes were collected in five height zones, from the forest floor to the canopy of eight canopy trees per locality. The sampling gene
