Aquatic oligochaetes associated with bryophytes in an Atlantic Forest stream Biota Neotropica
Rodrigues,Luciana Falci Theza; Santana,Lucas Deziderio; Alves,Roberto da Gama.
There are few reports in the literature about the colonization of benthic macroinvertebrates on bryophytes. The aim of the present study was to analyzed the oligochaetes established on bryophytes adhered to stones in a first-order stream. The collections were carried out in an Atlantic Forest fragment area during the dry and rainy seasons. We identified 15 taxa from a total of 422 oligochaetes specimens, of which the most abundant were Pristina sp.1, Enchytraeidae and Pristina jenkinae. Unlike other habitats, where the abundance of macroinvertebrates tends to be greater in the dry season, we did not find any significant differences in the abundance, richness, composition and diversity between the two periods. The results of this study indicate that...

Biogeography of Mindoro mosses Naturalis
Linis, V.C..
The moss flora of Mindoro Island was updated based on the 2004–2006 expeditions conducted by the author. The island’s moss flora now consists of 282 species in 128 genera and 39 families, which is higher than Palawan but far less than those of Luzon and Mindanao. Generally, the flora is most abundant in the eastern rainy part of the island, especially along mid-elevations on the east-facing slope of the central mountain range in the transition zone between montane and mossy forests. Moss diversity is also greater in riverine forests than in inland forests at low elevations. Only three moss taxa, Rhaccocarpus alpinus, Dicranoloma daymannianum and Distichophyllum noguchianum, have their Philippine range restricted to the island. Distichophyllum noguchianum...

BIOPROSPECTING: A TOOL TO CONSERVE CHILEAN BRYOPHYTES Gayana Botánica
Cuvertino-Santoni,Jorge; Montenegro,Gloria.
Here, we present the current state of knowledge on the diversity of Chilean bryophytes (mosses, liverworts, and hornworts), the secondary metabolites present in these plants, and the biological activity of extracts from populations of Chilean species. Our goal is to establish the potential of these plants as a source of useful molecules for pharmaceutical and agricultural industries, thus promoting their conservation. Only 3,7% of Chilean bryophytes (55 spp.) have been analyzed using chemical characterization of their extracts (methanol, ether, ethanol, dichloromethane, acetone and hexane). Only four species from Chilean and Argentinian populations (Porella chilensis (Lehm. & Lindenb.) Trevi., Riccardiapolyclada (Mitt. ex Thurn) Hässel,...

Bryophyte communities of restingas in Northeastern Brazil and their similarity to those of other restingas in the country Acta Botanica
Silva,Mércia Patrícia Pereira; Zickel,Carmen Sílvia; Pôrto,Kátia Cavalcanti.
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 of restinga in the Northeastern Region and to establish their floristic affinities with other restingas in Brazil. Fifty-five species were found in the studied restingas, the vast majority of which are generalist species with life forms of intermediate tolerance to desiccation and of corticicolous and terrestrial habitat. The number of species per area is low compared to the species richness of other...

Can regional and local filters explain epiphytic bryophyte distributions in the Atlantic Forest of southeastern Brazil? Acta Botanica
Batista,Wanessa Vieira Silva Menezes; Santos,Nivea Dias dos.
ABSTRACT Environmental conditions in distinct tropical rainforest phytophysiognomies can act as regional filters in determining the distribution of montane bryoflora likewise, local filters inherent to phorophyte species can have modulating influences. We analyzed the bryophyte communities in three phytophysiognomies of Atlantic Forest, in order to examine the influences of local (phorophyte species) and regional (forest phytophysiognomies) filters on their distributions. The study was undertaken in the Serra do Mar State Park, Ubatuba, SP, Brazil, using 1 ha plots in three forest phytophysiognomies along an elevational gradient. Four phorophyte species were selected, with three to seven replicates each. The line-intercept method was used on each...

Complex sporoderm structure in bryophyte spores: a palynological study of Erpodiaceae Broth. Acta Botanica
Luizi-Ponzo,Andrea Pereira; Silva-e-Costa,Juliana da Costa.
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 morphology and ultrastructure of spores of five species of Erpodiaceae (Bryophyta), and assessed the implications for taxonomy and the recognition of spores of past records. Erpodiaceae includes corticolous and saxicolous plants that are widely distributed throughout tropical and temperate regions. The spores were found to be isomorphic and apolar with a subcircular amb, granulate, inaperturate. The...

Distribution, ecology, and reproduction of bryophytes in a humid enclave in the semiarid region of northeastern Brazil Acta Botanica
Batista,Wanessa Vieira Silva Menezes; Pôrto,Kátia Cavalcanti; Santos,Nivea Dias dos.
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 Araripe, analyzing their diversity, geographic distributions, and ecological and reproductive aspects. Bryophytes were collected from different substrates using the random-walk method. We gathered information concerning the geographic distribution, functional groups (life forms, light tolerance guilds, and habits) and reproductive aspects of each taxon. We found 76 bryophyte species, predominantly...

Diversity and distribution of the bryophyte flora in montane forests in the Chapada Diamantina region of Brazil Acta Botanica
Valente,Emilia de Brito; Pôrto,Kátia Cavalcanti; Bastos,Cid José Passos; Ballejos-Loyola,Jana.
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...

Floristic overview of the epiphytic bryophytes of terra firme forests across the Amazon basin Acta Botanica
Oliveira,Sylvia Mota de; ter Steege,Hans.
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 generated 3104 records, identifying 222 species and 39 morphospecies, within 29 families. The most common families were Lejeuneaceae (in 55%), Calymperaceae (in 8%), Leucobryaceae (in 4%) and Sematophyllaceae (in 4%). Richness and species composition did not show any geographical gradient. The bryoflora was significantly richer in the localities of Saül, in French Guiana, and Tiputini, in Ecuador, than in...

Habitat heterogeneity and diversity of bryophytes in campos rupestres Acta Botanica
Valente,Emilia de Brito; Pôrto,Kátia Cavalcanti; Bastos,Cid José Passos.
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...

Naididae (Annelida, Oligochaeta) associated with briophytes in Brotas, State of São Paulo, Brazil Zoologia
Gorni,Guilherme Rossi; Alves,Roberto da Gama.
Mosses and liverworts can be colonized by various invertebrates, including fresh water oligochaete worms. However, little information is available on the habits and habitats of this oligochaetes in Brazil. Therefore, the present study was undertaken to examine the occurrence of naidids in mosses, as well as to broaden the knowledge about the habitats of these oligochaetes. Sampling of bryophytes adhered to rock substrates in the rapids of the Jacaré Pepira River (municipality of Brotas, São Paulo, Brazil) and to a vertical rock wall of a waterfall near the river revealed 191 Naididae individuals of the species Naiscommunis Piguet, 1906, Pristinellajenkinae (Stephenson, 1931) and Pristinellamenoni (Aiyer, 1929). We believe this to be the first record of...

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-way analysis and by cluster analysis, respectively. In total, 54 species of 13 families were identified. Richness was greater in igapó forest (44 species) compared to várzea forest (38 species). There was no significant difference in the number of species between the studied periods. Cluster analysis showed the bryoflora composition was different between várzea and igapó, but not between dry and rainy...
