Four new combinations in Chomelia and Stenostomum (Rubiaceae, Guettardeae) from Central America, the Guianas and the Amazon Basin
Provedor de dados: 16
Autores: Delprete, P.G.; Achille, F.; Mouly, A.
According to current generic delimitations, supported by wood anatomy, palynology, and recent molecular phylogenies, Antirhea, traditionally treated as a Pantropical genus, is instead restricted to the Paleotropics. At the same time, the Neotropical species traditionally positioned in Antirhea should be positioned in Stenostomum. Following these definitions, Stenostomum is a genus with most of the species present in the Caribbean Region, and two species present in the Guianas, namely S. acreanum and S. guianensis, distributed throughout the Amazon Basin. In addition, according to these new generic delimitations, two species previously positioned in Guettarda and Antirhea need to be transferred to Chomelia, as C. triflora and C. ulei.

Provedor de dados: 16
Autores: Delprete, P.G.
During the preparation of the treatment of the family Rubiaceae for the Flora of the Guianas, two new species of Coussarea were discovered. One species, Coussarea longilaciniata, was collected in Guyana and is characterized by its long-lanceolate calyx lobes; the other, C. spicata, is from French Guiana and is unique in the genus by its spicate inflorescences. In addition, Faramea sessiliflora var. pedunculata is here elevated to the species level, and a new description of F. sessiliflora is also provided in view of the re-delimitation of this species.

A new species of Sipapoantha (Gentianaceae: Helieae) from northern Brazil
Provedor de dados: 16
Autores: Lepis, K.B.; Maas, P.J.M.; Struwe, L.
A new species from Gentianaceae (tribe Helieae) is described from northern Brazil. Sipapoantha obtusisepala sp. nov. is distinct from the previously single member of the genus, Sipapoantha ostrina, by having a woody and branched habit, sessile and ovate leaves with an acute apex, and a smaller calyx with circular lobes. Sipapoantha obtusisepala is based on somewhat incomplete material and tentatively placed in Sipapoantha based on the presence of key generic characters such as coriaceous leaves with strongly revolute margins and blue corollas. It has only been recorded from one locality in the Brazilian-Guyana border area in the state of Roraima.

Provedor de dados: 88
Autores: Conceição,Abel Augusto; Pirani,José Rubens; Meirelles,Sergio Tadeu.
Soil islands on rocky surfaces often harbor aggregated vegetation that consists of insular plant communities. These islands are typical of the rocky outcrops and in various parts of Brazil form the so-called "campos rupestres" vegetation. Four of such sites have been selected in the state of Bahia, Northeast Brazil, for this comparative study on floristics and vegetation structure: three areas situated inside the "Parque Nacional da Chapada Diamantina" (Guiné, Fumaça and "Gerais da Fumaça") and one is at the border of the Environmental Protection Area of "Marimbus-Iraquara" ("Mãe Inácia"). All occurring vegetation islands were studied in four random plots of 10 × 10 m per site. Soil was often shallow, sandy and acidic. Vascular plant species were...

Autores: Salm,Rodolfo.
This study investigates patterns of forest structure and tree species diversity in an anthropogenic palm grove and undisturbed areas at the seasonally-dry Pinkaití research station, in the Kayapó Indigenous Area. This site, managed by the Conservation International do Brasil, is the most southeastern site floristically surveyed in the Amazon until now. The secondary and a nearby undisturbed forest were sampled in a group of 52 floristic plots of 0.0625-ha (25x25-m) where all trees with DBH &gt; 10 cm were measured and identified. The analyses were complemented with other two floristic plots of 1-ha (10x1000-m). The present study has shown that the Pinkaití, like other seasonally-dry forests, have great heterogeneity in forest structure and composition,...

ABSTRACT Shade-tolerant forest species are among the most susceptible to habitat loss in agricultural mosaics, where a variety of croplands is connected to forests at different levels of anthropogenic disturbance. We aimed to evaluate the community similarity of shade-tolerant species among different land use types across agricultural mosaics with different levels of disturbance. The study was conducted in three municipalities in southern and southeastern Pará state, in eastern Amazonia. A multiple-community similarity measure based on the Horn similarity index was used to compare land use types and assess the resilience of shade-tolerant species towards forest loss and disturbance at the landscape level. High shade-tolerant species similarity was found...

Generic additions to the Rapateaceae of Rondônia, Brazil
Provedor de dados: 36
Autores: RODRIGUES,Rodrigo Schütz.
ABSTRACT Rapateaceae is a monocot family centered in the Guiana Shield region of South America. This article reports four generic additions to the Rapateaceae of Rondônia, a state in northern Brazil. Cephalostemon gracilis (Poepp. &amp; Endl.) R.H.Schomb., Duckea cyperaceoidea (Ducke) Maguire, Monotrema xyridoides Gleason, and Schoenocephalium cucullatum Maguire were recorded in lowland savannas and open white-sand ecosystems in the state. These findings extend significantly the known diversity of the Rapateaceae taxa occurring in Rondônia, and represent an extension of their geographical distribution to a Brazilian state with no part of its territory in the Guiana Shield.

Field collection and herbaria data did not allow to quantify the diversity of aquatic plants from Northern Brazil, so we could not detect biogeographic patterns. Therefore, our objectives were to identify and quantify the aquatic macrophytes of North Brazilian states, analyzing herbaria data plataforms (SpeciesLink and Flora do Brasil). The checklist was produced by bibliographic search (articles published between 1980 and 2000), herbaria collections of the platforms SpeciesLink and Flora do Brasil and field expeditions, where we utilized asystematic sampling. We also analyzed the floristic similarity of aquatic macrophytes among Northern Brazil, wetlands of distinct Brazilian regions and the Neotropics. We recorded 539 species, of which 48 are endemic to...

Angiosperm disjunction "Campos rupestres - restingas": a re-evaluation
Provedor de dados: 39
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: 39
Autores: Eggers,Lilian; Marchioretto,Rafaella; Souza-Chies,Tatiana T.; Chauveau,Olivier.
ABSTRACT A taxonomic synopsis of Cypella (Iridaceae) in Brazil is presented with recognition of 16 species, two of them represented by two subspecies. An identification key to the taxa is provided and species are described and illustrated. New synonyms are indicated, and eight lectotypes, two epitypes and one neotype are designated. Results include distribution, habitat, phenology, conservation status, notes and examined specimens of all taxa, as well as comments on dubious and misused names. The resulting framework revealed that most of the Brazilian species of Cypella occur in the state of Rio Grande do Sul and in the Pampa Biome, although Río de la Plata grasslands (RPG) is the most species-rich biogeographic unit of the genus.

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...

Autores: Batalha,Marco Antônio; Mantovani,Waldir.
We studied a 1225 ha area, composed mainly of cerrado, in Santa Rita do Passa Quatro, São Paulo State, southeastern Brazil (21°36-38'S, 47°36-39'W). In three cerrado physiognomies (campo cerrado -- a wooded savanna, cerrado sensu stricto -- a woodland, and cerradão -- a tall woodland), we collected all vascular plants in reproductive stage, and identified them to species level. We found 360 species, representing 236 genera and 69 families. The richest families were: Asteraceae, Fabaceae, Poaceae, and Rubiaceae. The savanna physiognomies were richer than the forest one. The ratio between herbaceous and woody species was approximately 2:1. We analysed the whole flora and its two components separately, woody and herbaceous, comparing them with other disjunct...

Autores: Nettesheim,Felipe Cito; Garbin,Mário Luís; Pereira,Marcos Gervasio; Araujo,Dorothy Sue Dunn de.
ABSTRACT Tropical forests with high species diversity are commonly found in rugged montane areas. We investigated causes of local tropical forest tree community assembly on a continental island with heterogeneous terrain. We recorded tree community (absolute species abundance), topography, soil, litter and location in 40 sampling units on two opposite sides of the island with similar heterogeneous terrain. We used transformation based Redundancy Analyses and variation partitioning to determine the contribution of environment (topography, soil and litter), spatial structure (geographic location and Moran Eigenvector Maps) and the shared effects of these to explain community assembly. The environment made a significant contribution to explain tree community...

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...

ABSTRACT The Brazilian Pantanal is an extensive wetland with heterogeneous habitats, primarily due to the river-floodplain system and plants with differential adaptations and reproductive strategies. Factors such as altitude, distance among plant formations, and flood pulse must be considered to better understand its diversity. Aiming to assess the influence of biogeographic patterns in this system, we analyzed the floristic composition of six areas along the Paraguay River, including residual relieves, verifying the pattern of similarity, and effects of distance and altitude. We recorded 356 species in 87 families, mostly perennial (75%), and some annuals (15%) and pluriannuals (5%). Herbaceous plants were the most represented (48%), followed by arboreal...

Provedor de dados: 42
Autores: CERQUEIRA,GABRIELA R.; ILKIU-BORGES,ANNA LUIZA; FERREIRA,LEANDRO V.
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...

Provedor de dados: 42
Autores: LIMA-VERDE,LUIZ W.; LOIOLA,MARIA I.B.; FREITAS,BRENO M.
Information about the use of floristic resources of the immediate edges of ombrophilous forest (Atlantic rainforest) fragments by stingless bees is not readily available in the scientific literature. Considering the importance of these plant species for local guilds of stingless bees, this study aimed to identify and characterize the flora of the immediate borders of four Atlantic rainforest fragments situated in Baturité massif, state of Ceará, used as food resource by stingless bees. We studied the growth-form of the plants, the floristic similarity between edges and the effect of rainfall on the flowering, and suggested simple techniques for handling these areas. We compiled a total of 82 plant species with a predominance of tree and shrub form. There...

Provedor de dados: 49
Autores: Brito,Aline Franco Sampaio; Souza,Élvia Rodrigues de; Conceição,Adilva de Souza.
Abstract: Leguminosae includes six subfamilies, where the traditionally recognised subfamily Mimosoideae was accepted as a distinct clade included within the recircumscribed subfamily Caesalpinioideae, called informally as Mimosoid clade. The representatives of the tribes Acacieae and Ingeae can be differentiated principally in terms of the patterns of their stamens, being free in Acacieae and monadelphous in Ingeae. The floristic survey of Acacieae and Ingeae in the Environmental Protection Area Serra Branca included analysis of specimens collected from June 2011 to September 2012. The analyses were supplemented with dried collections from the following herbaria: ALCB, HRB and HUEFS. Ten species were cataloged, distributed among four genera of Ingeae:...

The Flora of Paraíba State, Brazil: subfamilies Ajugoideae and Viticoideae (Lamiaceae)
Provedor de dados: 49
Autores: Monteiro,Fernanda Kalina da Silva; Pastore,José Floriano Barêa; Melo,José Iranildo Miranda de.
Abstract: The Lamiaceae family includes about 7,000 species allocated in 236 genera, with almost cosmopolitan distribution, currently divided into nine subfamilies. In Brazil 46 genera and 525 species occur, distributed in four subfamilies. Among these subfamilies, Ajugoideae and Viticoideae were originally parts of the Verbenaceae family, being transferred to Lamiaceae as a result of several systematic studies on the two families. Ajugoideae is characterized by having drupes with four mericarps, non-persistent styles and pollen grains with exine formed by granular and branched columns. On the other hand, Viticoideae is characterized to have drupes with 4-locular pyrenes or 2 2-locular pyrenes and exine microreticulate or slightly rough. We present here...

The vascular flora of the cerrado in Emas National Park (Central Brazil): a savanna flora summarized
Provedor de dados: 52
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...
