An Annotated Checklist of the Vascular Flora of Guinea-Bissau (West Africa)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Catarino, L.; Martins, E.S.; Pinto Basto, M.F.; Diniz, M.A.
A Checklist of Guinea-Bissau’s vascular flora is presented, based on the inventory of herbarium material and on recent collections. In addition to the name, we cite for each taxon the basionym and synonyms, the life form and habitat, as well as the chorology, Raunkiaer’s biological type, phenology and vernacular names if known. 1507 specific and infra-specific taxa were recorded, of which 1459 are autochthonous, belonging to 696 genera. This shows a higher diversity than the 1000 species estimated so far. In the autochthonous flora there are 22 species of Pteridophyta from 14 families; 1041 taxa of Dicotyledons from 107 families, and 396 taxa of Monocotyledons belonging to 33 families. Three taxa are probably endemic to the country.

Species richness and origin of the bryophyte flora of the Colombian Andes
Provedor de dados: Naturalis Digital Academic Repository
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...

Rock outcrop habitats in the Venezuelan Guayana lowlands: their main vegetation types and floristic components
Provedor de dados: Revista Brasileira de Botânica
Autores: Gröger,Andreas; Huber,Otto.
The Guayana Shield, located in north-eastern South America, consists of a highly complex and composite mosaic of landscape elements. Amongst these, inselbergs are very conspicuous, because of their peculiar shape and their unusual associated vegetation. Geologically, these rock outcrops are part of the underlying ancient igneous-metamorphic basement and occur mainly in the lowlands of the periphery of the shield. As azonal habitats, inselbergs harbour a highly specialized flora. The characteristic vegetation is composed of lithophytic and savanna-like plant communities, as well as low dry forests. As a whole, the vegetation of an inselberg may be interpreted as a mosaic of marginal habitats. Therefore a large number of taxa find suitable niches in a quite...

Plant species and habitat structure in a sand dune field in the brazilian Caatinga: a homogeneous habitat harbouring an endemic biota
Provedor de dados: Revista Brasileira de Botânica
Autores: Rocha,Pedro Luís B. da; Queiroz,Luciano P. de; Pirani,José Rubens.
One dune habitat in the semi-arid Caatinga Biome, rich in endemisms, is described based on plant species composition, woody plant density, mean height and phenology and a multivariate analysis of the micro-habitats generated by variables associated to plants and topography. The local flora is composed mainly by typically sand-dweller species of Caatinga, suggesting the existence of a phytogeographic unity related to the sandy areas in the Caatinga biome, which seems to be corroborated by faunal distribution. Moreover, some species are probably endemic from the dunes, a pattern also found in vertebrates. The plant distribution is patchy, there is no conspicuous herbaceous layer and almost 50% of the ground represents exposed sand. Phenology is not...

Composição, estrutura e relações florísticas do componente arbóreo de uma floresta estacional no Rio Grande do Sul, Brasil
Provedor de dados: Revista Brasileira de Botânica
Autores: JARENKOW,JOÃO ANDRÉ; WAECHTER,JORGE LUIZ.
A composição específica de florestas estacionais no Rio Grande do Sul é fortemente influenciada por dois contingentes florísticos diferentes, um coincidente com as florestas atlânticas do leste e outro com as florestas paranaense-uruguaias do oeste. Um levantamento fitossociológico de uma floresta central sul-rio-grandense foi realizado para detectar a estrutura comunitária do componente arbóreo e a participação local dos diferentes contingentes florísticos. Todas as árvores com DAP  &gt; ou =  5 cm foram registradas em uma área de 1 ha, subdividida em 100 unidades amostrais de 10 x 10 m. As espécies amostradas foram classificadas como amplas ou restritas, segundo suas distribuições geográficas, considerando as afinidades florísticas leste ou oeste. A...

Distribution of grasses along an altitudinal gradient in a Venezuelan paramo
Provedor de dados: Revista Chilena de Historia Natural
Autores: MÁRQUEZ,EDJULY J.; FARIÑAS,MARIO R.; BRICEÑO,BENITO; RADA,FERMÍN J.
In Venezuelan paramos grasses, after Asteraceae, are the second family in numerical importance. We studied their distribution in an altitudinal gradient located in Venezuela, Sierra de La Culata, between 2,500 and 4,200 m of altitude. Twenty one 32 m parallel line transects every 50 m were placed along the gradient, perpendicular to the main slope. Each line was divided into contiguous 50 x 50 cm sampling units. Grass species occurrence inside each sample unit was considered to determine their frequency in each line or altitude. The peak and altitudinal amplitude was determined through the weighted averaging method. A total of 47 grass species were found along the gradient. Agrostis was the best-represented genus in the gradient. Considering the...

Angiosperm disjunction "Campos rupestres - restingas": a re-evaluation
Provedor de dados: Acta Botanica Brasilica
Autores: Alves,Ruy José Válka; Cardin,Leonora; Kropf,Marcela Stuker.
A disjunct distribution pattern between the extrazonal formations of the campos rupestres (rocky grasslands) in the Espinhaço mountain range and the restingas (coastal strand vegetation) in Brazil has been proposed repeatedly for several flowering-plant species. In order to validate this distribution pattern, available data from the literature and major herbaria were compiled and evaluated. Some of these species also occur in campos rupestres on mountain ranges in Goiás state, campos de altitude (high altitude grasslands) of the Serra do Mar, and on geologically homologous rocky formations of the Guyana shield. Species that were also recorded for distinct zonal formations like cerrado, caatinga and forests were excluded from the pattern. The campo...

Provedor de dados: Acta Botanica Brasilica
Autores: Sühs,Rafael Barbizan; Hoeltgebaum,Marcia Patricia; Nuernberg-Silva,Anelise; Fiaschi,Pedro; Neckel-Oliveira,Selvino; Peroni,Nivaldo.
ABSTRACT Upper montane ecosystems in Brazil are little known, and their structural and functional aspects poorly understood. Our goals were to describe tree species diversity and community structure, and to characterize tree species in relation to their ecological traits, phytogeographic history and conservation status in an upper montane araucaria forest remnant. A total of 26 species belonging to 18 families were found in a 1-hectare permanent plot. The tree community mainly comprised trees with diameters of less than 20 cm and heights of between 6.5 and 9.5 m. Drimys angustifolia and Myrceugenia regnelliana had the highest importance values. Most species were shade tolerant while most individuals were pioneers. Most species and individuals presented...

Mixed rain forest in southeastern Brazil: tree species regeneration and floristic relationships in a remaining stretch of forest near the city of Itaberá, Brazil
Provedor de dados: Acta Botanica Brasilica
Autores: Ribeiro,Tiago Maciel; Ivanauskas,Natália Macedo; Martins,Sebastião Venâncio; Polisel,Rodrigo Trassi; Santos,Rochelle Lima Ramos dos; Miranda Neto,Aurino.
The aim of this work was to evaluate the floristic composition, richness, and diversity of the upper and lower strata of a stretch of mixed rain forest near the city of Itaberá, in southeastern Brazil. We also investigated the differences between this conservation area and other stretches of mixed rain forest in southern and southeastern Brazil, as well as other nearby forest formations, in terms of their floristic relationships. For our survey of the upper stratum (diameter at breast height [DBH] &amp;gt; 15 cm), we established 50 permanent plots of 10 × 20 m. Within each of those plots, we designated five, randomly located, 1 × 1 m subplots, in order to survey the lower stratum (total height &amp;gt; 30 cm and DBH &lt; 15 cm). In the upper stratum, we...

Influence of environmental variation on Atlantic Forest tree-shrub-layer phytogeography in southeast Brazil
Provedor de dados: Acta Botanica Brasilica
Autores: Nettesheim,Felipe Cito; Menezes,Luis Fernando Tavares de; Carvalho,Daniel Costa de; Conde,Marilena Menezes Silva; Araujo,Dorothy Sue Dunn de.
This work assessed data from 32 forest sites in Rio de Janeiro and São Paulo, Brazil, using multivariate analysis to answer the question: Are there floristic patterns of the Atlantic Forest tree-shrub layer related to the Serra do Mar and the width of coastal plains in the states of Rio de Janeiro and São Paulo? Three multivariate analyses were performed to investigate the relationship between the tree-shrub flora and environmental variation in these 32 study areas. Our analyses demonstrated the influence of geo-climatic variation on floristic differentiation of tree and shrub species in Atlantic Forest regions generating groups of areas based on similar biotic and abiotic characteristics. These groups support the existence of floristic patterns within the...

Distribution patterns of ferns and lycophytes in the Coastal Region of the state of Rio Grande do Sul, Brazil
Provedor de dados: Acta Botanica Brasilica
Autores: Gonzatti,Felipe; Machado,Letícia; Windisch,Paulo Günter.
ABSTRACT A survey of ferns and lycophytes of the Coastal Region of the state of Rio Grande do Sul (CRRS) was performed based on field work and collections of the main regional herbaria. The following were evaluated for each species: preferential habits (terrestrial, epiphytic or aquatic), geographic distribution patterns and habitats (forest, grassland, and wetland). The occurrence of a latitudinal gradient in diversity was tested over five latitudinal ranges using the Sørensen Similarity Index. A total of 17 lycophyte and 206 fern species representing 28 families was found between the latitudes of 29° and 34°S. Exclusively terrestrial species were predominant (162), with the majority (113) exhibiting wide Neotropical distributions, followed by species...

Structure and phytogeographic relationships of swamp forests of Southeast Brazil
Provedor de dados: Acta Botanica Brasilica
Autores: Kurtz,Bruno Coutinho; Gomes,Jorge Caruzo; Scarano,Fabio Rubio.
Swamp forests are associated with soils that are saturated or inundated because of a high water table. In Brazil, little is known about the plant ecology of such forests. In this paper, we aimed to describe the phytosociological structure of the tree layer of swamp forests in Restinga de Jurubatiba National Park, in the northern part of the state of Rio de Janeiro, and to evaluate the floristic similarities between these forests and some other possibly related types of vegetation formations in Brazil. The sampling included 84 species, within 62 genera and 34 families. The Shannon diversity index was 3.42, and the Shannon evenness index was 0.77. The forests studied showed an oligarchic structure; Tapirira guianensis, Calophyllum brasiliense and Protium...

Patterns of species diversity in different spatial scales and spatial heterogeneity on beta diversity
Provedor de dados: Acta Botanica Brasilica
Autores: Soares,Caio J. R. S.; Sampaio,Mauricio B.; Santos-Filho,Francisco S.; Martins,Fernando R.; Santos,Flavio A. M. dos.
ABSTRACT Patterns of species diversity are essential to understand community structure. We aimed to determine species diversity and patterns of beta diversity in different spatial scales. We sampled three thousand individuals between the coordinates 22°10'S to 22°16'S and 47°47'W to 48°00'W to assess species diversity in three spatial scales (maximum distances of 80 m, 1,400 m, and 12,000 m), using the point-centered-quarter method. We partitioned gamma diversity into alpha and beta components. Beta diversity was partitioned into dissimilarities produced by spatial species turnover and nestedness. The contribution of beta diversity to gamma diversity was greater than that of alpha diversity in all scales, although the patterns of species diversity were...

Autores: Giaretta,Augusto; Menezes,Luis Fernando Tavares de; Pereira,Oberdan José.
The Brazilian shrublands area (restinga) is composed of marine coast vegetation on Quaternary sandy plains, where the species composition can vary depending on the surrounding ecosystems. The aims of this study were to describe the structure and floristic composition of a restinga near the community of Itaúnas, in the northern part of the state of Espírito Santo, to identify any relationships between this restinga and surrounding plant formations, and to determine which are the species that occur preferentially in the coastal forests of Espírito Santo. We sampled woody plants with a diameter at breast height &gt; 2.5 cm, excluding lianas, in 50 plots of 100 m². We selected studies of coastal forests in the states of Espírito Santo and Bahia to prepare a...

Permian plants from the Chutani Formation (Titicaca Group, Northern Altiplano of Bolivia): II. The morphogenus Glossopteris
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Iannuzzi,Roberto; Vieira,Carlos E. L.; Guerra-Sommer,Margot; Díaz-Martínez,Enrique; Grader,George W.
Fossil plants belonging to the morphogenera Glossopteris, Pecopteris and Asterotheca were collected from the upper part of the Chutani Formation (Titicaca Group), near the town of San Pablo de Tiquina, on the southeastern shore of Lake Titicaca (northern Altiplano, Bolivia). This paper presents the first description of specimens of the morphogenus Glossopteris from Bolivia. The Bolivian specimens of Glossopteris consist of poorly-preserved impressions, although they present the diagnostic features of this morphogenus. They are fragments of leaves with secondary veins of taeniopterid-type, typical of glossopterids from Late Permian deposits of Gondwana. The only species of Pecopteris confirmed in the first part of this study, i.e. P. dolianitii Rösler and...

Phytogeographical patterns of dry forests sensu stricto in northern Minas Gerais State, Brazil
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: ARRUDA,DANIEL M.; FERREIRA-JUNIOR,WALNIR G.; DUQUE-BRASIL,REINALDO; SCHAEFER,CARLOS E.R.
The Deciduous Complex that occurs in northern Minas Gerais State, Brazil, raises questions about the floristic affinities of these formations in relation to neighboring phytogeographical domains. Little is known about the identity of the seasonal forest formations that comprise this complex, or about its relationships to abiotic components, such as soils, topography and climate. This study aimed to recognize the patterns of floristic similarity of all studied fragments of dry forest of northern Minas Gerais with soil and climate attributes, based on the available database. Cluster analysis indicated the existence of two floristic groups that had clear associations with either the Koppen's BSh (semi-arid) or Aw (seasonal tropical) climates. Likewise, the...

A new world natural vegetation map for global change studies
Provedor de dados: Anais da Academia Brasileira de Ciências
Autores: Lapola,David M.; Oyama,Marcos D.; Nobre,Carlos A.; Sampaio,Gilvan.
We developed a new world natural vegetation map at 1 degree horizontal resolution for use in global climate models. We used the Dorman and Sellers vegetation classification with inclusion of a new biome: tropical seasonal forest, which refers to both deciduous and semi-deciduous tropical forests. SSiB biogeophysical parameters values for this new biome type are presented. Under this new vegetation classification we obtained a consensus map between two global natural vegetation maps widely used in climate studies. We found that these two maps assign different biomes in ca. 1/3 of the continental grid points. To obtain a new global natural vegetation map, non-consensus areas were filled according to regional consensus based on more than 100 regional maps...

This study describes the tree and shrub component of the Atlantic Forest on the slopes of Marambaia Island, RJ. It further evaluates which species are found at threatened species lists and the similarity that the studied forest component has with other nearby locations with similar vegetation. Data gathering relied on the joint effort of arbitrary walks and sampling units known as Transect. The same sampling criterion was applied at both approaches (DBH greater than or equal to 5 cm). A similarity analysis, followed by a Cluster analysis, was used to compare the studied vegetation component. Similarity calculations were based in the Bray-Curtis coefficient. We detected a total of 235 species. These are divided in 134 genera and 52 families. The richest...

The adaptive value of shoot differentiation in deciduous trees and its evolutionary relevance
Provedor de dados: Boletín de la Sociedad Argentina de Botánica
Autores: Dörken,Veit M.; Stützel,Thomas.
Pronounced long shoot/short shoot differentiation is typical for deciduous angiosperm trees. It also occurs in a number of gymnosperms and very few evergreen angiosperm trees. The study of 719 angiosperm tree species (602 deciduous and 117 evergreen species) demonstrated that the deciduous condition is nearly always associated with shoot differentiation. Detailed measurements in 38 angiosperms showed that the leaf area of an entire short shoot equals the leaf area of a single long shoot leaf of the same species and individual. In the few cases where the leaf area of the short shoot is slightly larger than that of a single long-shoot leaf, the short shoot leaves shade each other and the projection of the short shoot equals the area of a single long shoot...

The vascular flora of the cerrado in Emas National Park (Central Brazil): a savanna flora summarized
Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Batalha,Marco Antônio; Martins,Fernando Roberto.
The Brazilian cerrado may be divided in two main phytogeographic sectors: one characterized by Piptocarpha rotundifolia, in which the Emas National Park (ENP) is located, and other characterized by Curatella americana. We carried out a floristic survey in ENP, which allowed an assessment of the taxonomic composition, taxa size, and similarity with other sites for the ENP's vascular flora. We compared the ENP's flora with southeastern outlying cerrado sites, also in the Piptocarpha sector, and with general floristic patterns in the cerrado vegetation. The distribution of species per family in ENP was significantly different from that obtained for each component of the general cerrado flora. The herbaceous component was characterized by an overproportion of...
