A remarkable new species of Cheilolejeunea (Marchantiophyta: Lejeuneaceae) from Colombia Boletín de la Sociedad
Gradstein,S. Robbert; Reiner-Drehwald,M. Elena.
We describe the new liverwort species Cheilolejeunea schiavoneana M.E.Reiner & Gradst. from submontane rainforest in the Western Cordillera of Colombia. The new species is related to C. adnata (C. sect. Cheilolejeunea) but differs by larger plant, leaf and underleaf size, robust stems, a 5-6 cells wide ventral merophyte, abundance of microphyllous branches, and vegetative reproduction by caducous leaf lobes produced on flagelliform shoots. The latter feature is characteristic of the genus Rectolejeunea and its presence in Cheilolejeunea is apparently a case of parallel evolution. The discovery of C. schiavoneana adds a further endemic taxon to the rich flora of the Colombian Western Cordillera.

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,...

Nobre,Camila Pinheiro; Huertas,Orlando Carlos Tavares; Tardin,José Rogério Figueira; Saggin Júnior,Orivaldo José; Fonseca,Henrique Manoel Apolónia Coutinho; Berbara,Ricardo Luis Louro.
In this study, we evaluated the growth of the liverwort Lunularia cruciata, inoculated or not with the arbuscular mycorrhizal fungi (AMF) Glomus proliferum (15 spores per Petri dish), in Strullu-Romand Variant (SRV) medium modified and enriched with humic acid (HA) at different concentrations (0, 20, 40 and 80 mg C L−1), as well as the sporulation of the AMF. We assessed the absolute growth rate (AGR) and relative growth rate (RGR) at inoculation, as well as at 7, 14, 21, 28, 43, 52 and 60 days after inoculation (DAI), whereas we assessed sporulation at 25, 43, 60 and 70 DAI. The main determinant of L. cruciata growth was the presence of AMF. With and without G. proliferum inoculation, respectively, the AGR peaked at 39 and 42 DAI, and the RGR was 0.0474...

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...

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...

Species richness and distribution of bryophytes within different phytophysiognomies in the Chapada Diamantina region of Brazil Acta Botanica
Valente,Emilia de Brito; Pôrto,Kátia Cavalcanti; Bastos,Cid José Passos.
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%,...

Spore germination, early development and some notes on the effects of in vitro culture medium on Frullania ericoides (Nees) Mont. (Frullaniaceae, Marchantiophyta) Acta Botanica
Silva-e-Costa,Juliana da Costa; Luizi-Ponzo,Andrea Pereira; Resende,Cristiano Ferrara de; Peixoto,Paulo Henrique Pereira.
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, a leafy liverwort species. Fresh spores were inoculated in vitro in different culture strengths of Knop’s nutrient solution (one-fourth strength, half strength, full strength, one and a half strength and double strength), in order to evaluate the effects of this solution on spore germination and on the development of external protonema. On the first assessment, spore germination was observed at all the...

Spores of Plagiochila (Dumort.) Dumort.: the taxonomic relevance of morphology and ultrastructure Acta Botanica
Silva-e-Costa,Juliana da Costa; Luizi-Ponzo,Andrea Pereira.
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 involving Plagiochilaceae and Plagiochila. Here, we describe the spore morphology of seventeen species of Plagiochila and discuss the taxonomic value of palynological characters for these taxa. The spores were processed by standard palynological techniques and analyzed using light and electron microscopy. The spores were found to be apolar, spheroidal, released monads that vary in size from 13µm to 58µm...

The bryophytes of Trindade Island, South Atlantic, Brazil Acta Botanica
Faria,Allan Laid Alkimim; Carvalho-Silva,Micheline; Costa,Denise Pinheiro da; Câmara,Paulo Eduardo Aguiar Saraiva.
Trindade is a Brazilian oceanic island located about 1,200 Km east of the Brazilian coast (between 20º 31' 30" S, 29º 19' 30'' W). The island originated from the abissal zone about 3 million years ago, has a maximum altitude of 620 meters and an area of 9.28 Km². Even though the fanerogamic flora is known, there were virtually no data on the bryophyte flora. Four expeditions to the island were carried out during two years and approximately 431 specimens collected. This work presents the Bryoflora of this island, which comprises 32 species, including 20 species of liverworts distributed among six families; the most speciose being Lejeuneaceae with 11 species and Frullaniaceae with four. There are also 11 species of mosses distributed among eight families,...
