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. 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

3. 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

4. Complex sporoderm structure in bryophyte spores: a palynological study of Erpodiaceae Broth.
ABSTRACT Palynological studies of bryophytes are critical for evaluating the taxonomic relevance of their spores. They also provide important support to paleoecological investigations that, usually, treat bryophytes as a whole, which does not permit the evaluation of specific functional traits of a special taxonomic unit. The present study investigated the m

5. Distribution, ecology, and reproduction of bryophytes in a humid enclave in the semiarid region of northeastern Brazil
ABSTRACT The ready availability of water resources distinguishes the humid forest of Chapada do Araripe, Ceará State, Brazil, from the semiarid vegetation around it. The regional climate demonstrates a marked seasonality of rainfall that affects the ecological strategies of the species found there. We studied the bryophytes of the humid forest of Chapada do

6. Bryophyte richness of soil islands on rocky outcrops is not driven by island size or habitat heterogeneity
ABSTRACT The species-area relationship (SAR) is one of the oldest and most studied ecological models, having even served as the foundation of the Theory of Island Biogeography. Nevertheless, the relative importance of habitat heterogeneity to SAR remains poorly understood. Our aim was to test the relative importance of habitat heterogeneity to the SAR of bry

7. Species richness and composition of epiphytic bryophytes in flooded forests of Caxiuanã National Forest, Eastern Amazon, Brazil
ABSTRACT This study aimed to compare the richness and composition of the epiphytic bryoflora between várzea and igapó forests in Caxiuanã National Forest, Brazilian Amazon. Bryophytes were collected on 502 phorophytes of Virola surinamensis. Average richness per phorophyte and composition between forests and between dry and rainy periods was tested by two

8. 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,

9. Spore germination, early development and some notes on the effects of in vitro culture medium on Frullania ericoides (Nees) Mont. (Frullaniaceae, Marchantiophyta)
ABSTRACT In bryophytes, establishment can occur by a sexual or asexual process, but the production of spores enables colonization of a wider range of habitats and substrates than can asexual propagules. Successful germination is critical for establishment in a new environment. This paper addresses germination and sporeling development in Frullania ericoides,

10. Vertical distribution of epiphytic bryophytes in Atlantic Forest fragments in northeastern Brazil
ABSTRACT The microclimatic gradient established from the forest understory to the canopy provides a range of different conditions for the establishment of bryophytes along the height of a tree. We investigated epiphytic bryophyte communities of four fragments of Atlantic Forest with the aim of describing their vertical zonation and assessing differentiation

11. Bryophyte communities of restingas in Northeastern Brazil and their similarity to those of other restingas in the country
ABSTRACT Restingas are a coastal component of the Atlantic Forest. They experience high temperatures and possess soils with a low capacity to retain water, low nutrient content and high salt concentrations. Studies on bryophytes of restingas have been mostly conducted in Southeastern Brazil, and so we aimed to characterize the bryophyte flora of seven areas

12. Seasonality of reproduction of epiphytic bryophytes in flooded forests from the Caxiuanã National Forest, Eastern Amazon
Este trabalho teve como objetivo conhecer a biologia reprodutiva da brioflora epífita de forófitos de Virola surinamensis (Rol. ex. Rottb.) Warb. na várzea e igapó na Floresta Nacional de Caxiuanã, para responder à seguinte pergunta: O período de reprodução das espé cies de briófitas é influenciado pelo ambiente devido a sazonalidade climática p
