Provedor de dados: 74
Autores: Cevallos,Miguel A.; Guerrero,Gabriela; Ríos,Selma; Arroyo,Analilia; Villalobos,Miguel Angel; Porta,Helena.
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 Pseudocrossidium replicatum, a moss belonging to the Pottiaceae family that is common in the central highlands of Mexico, in South America, in southern USA, and in Kenia. The cp genome (plastome) of P. replicatum is 123,512 bp in size, comprising inverted repeats of 9,886 bp and single-copy regions of 85,146 bp (LSC) and 18,594 bp (SSC). The plastome encodes 82 different proteins, 31 different tRNAs, and 4...

Species richness and origin of the bryophyte flora of the Colombian Andes
Provedor de dados: 16
Autores: Gradstein, S.R.; Reenen, G.B.A. van; Griffin, D.
Based on data from the ECOANDES project, a phytogeographical analysis has been made of the bryophyte flora along the wet, foggy western slope (1000-4500 m) and the drier eastern slope (500-4500 m) of the Colombian Central Cordillera at the ‘Parque de los Nevados’. Species richness increases with altitude to the upper montane forest, which holds the largest diversity. Liverworts outnumber mosses in the upper submontane and montane forests on the western slope, but elsewhere, in drier environments, their number is lower and falls to below that of mosses. Furthermore, it appears that at lower altitudes, below 3000 m, wide-ranging tropical species prevail whereas narrowranging tropical species (andean and endemic element) and species of temperate origin are...

An approach to calculate a Species Temperature Index for flora based on open data
Provedor de dados: 16
Autores: Sparrius, L.B.; Top, G.G. van den; Swaay, C.A.M. van.
To study the relation between changes in local plant communities and shifts in temperature, the temperature niches of the species need to be defined. We calculated the Species Temperature Index (STI) as a proxy for this niche. STI is defined as the mean annual temperature within the range of a species. In this paper, a method is described to calculate the STI for the European flora from open data provided by the Global Biodiversity Information Facility (GBIF) and WorldClim global climate data, for 7254 taxa of European vascular plants, bryophytes, algae, and ascomycetes including lichens. The algorithm accounts for incomplete and unbalanced species distribution data. The Community Temperature Index (CTI) is defined as the weighted mean of the STIs of a...

Biogeography of Mindoro mosses
Provedor de dados: 16
Autores: 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...

Spore germination and young gametophyte development of the endemic Brazilian hornwort Notothylas vitalii Udar &amp;amp; Singh (Notothyladaceae - Anthocerotophyta), with insights into sporeling evolution
Provedor de dados: 39
Autores: Oliveira,Bárbara Azevedo; Pereira,Anna Flora de Novaes; Pôrto,Kátia Cavalcanti; Maciel-Silva,Adaíses Simone.
ABSTRACT Notothylas vitalii is an endemic Brazilian hornwort species, easily identified by the absence of pseudoelaters and columella, and the presence of yellow spores. Plant material was collected in Recife, Brazil, and the spores were sown onto Knop’s medium, germinating after thirty days only with the presence of light. Germination occurred outside the exospore, and only after the walls had separated into three or four sections did a globose sporeling initiate its development. Following longitudinal and transversal divisions, the initial loose mass of cells became a thalloid gametophyte, subsequently developing into a rosette-like juvenile thallus with flattened lobes. Additional information concerning sporeling types in key genera of hornworts, such...

Bryophyte flora in upland forests at different successional stages and in the various strata of host trees in northeastern Pará, Brazil
Provedor de dados: 39
Autores: Tavares-Martins,Ana Cláudia Caldeira; Lisboa,Regina Célia Lobato; Costa,Denise Pinheiro da.
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 various strata of host trees, in terms of the bryophyte species composition. Bryophyte specimens were collected between August 2005 and September 2006 from host trees in primary and secondary forests of different ages and of different heights, within the municipality of Capitão Poço, in the state of Pará. The vertical distribution of bryophytes was evaluated in 15 host trees within the primary forest. We...

Complex sporoderm structure in bryophyte spores: a palynological study of Erpodiaceae Broth.
Provedor de dados: 39
Autores: 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...

Richness of Marchantiophyta and Bryophyta in a protected area of the Brazilian Amazon
Provedor de dados: 39
Autores: Macedo,Luciana Priscila Costa; Ilkiu-Borges,Anna Luiza.
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 northeastern part of the state of Pará, because the latter shows similarities with the study area in terms of vegetation, geography, demography, and history of occupation. We recorded 983 occurrences of bryophytes (549 Marchantiophyta and 434 Bryophyta) corresponding to 62 species (43 liverworts and 19 mosses), 39 genera, and 12 families. Of those 62 species, 25 have previously been collected from all regions of...

Palynology of Amphidium Schimp. (Amphidiaceae M. Stech): can spore morphology circumscribe the genus?
Provedor de dados: 39
Autores: Passarella,Marcella de Almeida; Luizi-Ponzo,Andrea Pereira.
ABSTRACT Amphidium Schimp. is characterized by cushion-forming erect primary stems, linear-lanceolate leaves, and gymnostome capsules. The phylogenetic position of Amphidium is uncertain, with the genus having been variously included in Zygodontaceae Schimp., Rhabdoweisiaceae Limpr., Orthotrichaceae Arn. and Amphidiaceae M. Stech. A palynological investigation was performed of the three species of the genus that occur in the Americas: Amphidium lapponicum (Hedw.) Schimp., Amphidium mougeotii (Bruch &amp; Schimp.) Schimp., and Amphidium tortuosum (Hornsch.) Cufod. Spores were observed and measured for greatest diameter under light microscopy both before and after acetolysis. Non-acetolyzed spores were observed under scanning electron microscopy to assess...

Spores of Plagiochila (Dumort.) Dumort.: the taxonomic relevance of morphology and ultrastructure
Provedor de dados: 39
Autores: 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...

All green, but equal? Morphological traits and ecological implications on spores of three species of mosses in the Brazilian Atlantic forest
Provedor de dados: 42
Autores: MACIEL-SILVA,ADAÍSES S.; SILVA,FLÁVIA C.L. DA; VÁLIO,IVANY F.M.
Spores of the tropical mosses Pyrrhobryum spiniforme, Neckeropsis undulata and N. disticha were characterized regarding size, number per capsule and viability. Chemical substances were analyzed for P. spiniforme and N. undulata spores. Length of sporophyte seta (spore dispersal ability) was analyzed for P. spiniforme. Four to six colonies per species in each site (lowland and highland areas of an Atlantic Forest; Serra do Mar State Park, Brazil) were visited for the collection of capsules (2008 – 2009). Neckeropsis undulata in the highland area produced the largest spores (ca. 19 µm) with the highest viability. The smallest spores were found in N. disticha in the lowland (ca. 13 µm). Pyrrhobryum spiniforme produced more spores per capsule in the highland...

Soluble carbohydrate content variation in Sanionia uncinata and Polytrichastrum alpinum, two Antarctic mosses with contrasting desiccation capacities
Provedor de dados: 48
Autores: Zúñiga-González,Paz; Zúñiga,Gustavo E; Pizarro,Marisol; Casanova-Katny,Angélica.
BACKGROUND: Cryptogamic vegetation dominates the ice-free areas along the Antarctic Peninsula. The two mosses Sanionia uncinata and Polytrichastrum alpinum inhabit soils with contrasting water availability. Sanionia uncinata grows in soil with continuous water supply, while P. alpinum grows in sandy, non-flooded soils. Desiccation and rehydration experiments were carried out to test for differences in the rate of water loss and uptake, with non-structural carbohydrates analysed to test their role in these processes. RESULTS: Individual plants of S. uncinata lost water 60 % faster than P. alpinum; however, clumps of S. uncinata took longer to dry than those of P. alpinum (11 vs. 5 h, respectively). In contrast, rehydration took less than 10 min for both...

Bryophytes as a material to build birds&amp;#8217; nests in Brazil
Provedor de dados: 51
Autores: De Almeida Amélio,Leandro; Marchi Do Carmo,Dimas; Soares De Lima,Jéssica; Fernandes Peralta,Denilson.
Birds&amp;#8217; nests are elaborate constructions that are built to provide a safe and secure environment for the eggs and hatchlings of birds to develop. Twigs and leaves represent common nesting materials in birds&amp;#8217; nests globally and with their beaks, they can carry materials, sometimes larger than the birds themselves, to construct their nests. In addition to twigs and leaves, birds also use various other materials less frequently, such as bryophytes, and in this study we examined the prevalence of bryophytes in birds&amp;#8217; nests in Brazil. We analyzed the nest composition of 21 birds&amp;#8217; nests from the Brazilian bryophyte collection at the Institute of Botany (SP Herbarium) and found that bryophytes were a widely used nesting...
