A new glanapterygine catfish of the genus Listrura (Siluriformes: Trichomycteridae) from southeastern Brazil, corroborated by morphological and molecular data Neotropical Ichthyology
Villa-Verde,Leandro; Lazzarotto,Henrique; Lima,Sergio M. Q..
Listrura costai, new species, is described from small streams in a swampy coastal plain in the rio Jurumirim basin, Angra dos Reis Municipality, Rio de Janeiro State, southeastern Brazil. The new species is morphologically very similar to L. nematopteryx and L. picinguabae, all possessing only one long pectoral-fin ray. It differs from its congeners by possessing an autapomorphic character: first hypobranchial with an anterior process (vs. process absent). Other features such as coloration, numbers of opercular and interopercular odontodes, number of anal-fin rays, head length, and shape of some bone structures help to distinguish the new species from L. nematopteryx and L. picinguabae. Molecular analyses using partial sequences of the mitochondrial DNA...

A riqueza de espécies arbóreas na floresta atlântica de encosta no estado de São Paulo (Brasil) Rev. Bras. Bot.
TABARELLI,MARCELO; MANTOVANI,WALDIR.
Extensa literatura refere-se à floresta atlântica de encosta no estado de São Paulo como possuidora de elevada diversidade florística. Esta afirmação está baseada em dados e conclusões de estudos florísticos e fitossociológicos locais. A maioria destes trabalhos não define com clareza o que considera diversidade, de que grupos estão tratando, a escala de abordagem e, principalmente, quais as florestas usadas para comparação. Neste estudo, são comparados dados sobre riqueza de plantas arbóreas (<FONT FACE="Symbol">³</font> 2,5 cm dap) na floresta atlântica de encosta em São Paulo com os de outras florestas neotropicais. Posteriormente, são discutidas as principais relações conhecidas entre a riqueza de plantas lenhosas nas florestas neotropicais...

Bats from Fazenda Intervales, Southeastern Brazil: species account and comparison between different sampling methods Zoologia
Portfors,Christine V.; Fenton,M. Brock; Aguiar,Ludmilla M. de S.; Baumgarten,Julio E.; Vonhof,Maarten J.; Bouchard,Sylvie; Faria,Deborah M. de; Pedro,Wagner A.; Rauntenbach,Naas I. L.; Zortea,Marlon.
Assessing the composition of an area's bat fauna is typically accomplished by using captures or by monitoring echolocation calls with bat detectors. The two methods may not provide the same data regarding species composition. Mist nets and harp traps may be biased towards sampling low flying species, and bat detectors biased towards detecting high intensity echolocators. A comparison of the bat fauna of Fazenda Intervales, southeastern Brazil, as revealed by mist nets and harp trap captures, checking roosts and by monitoring echolocation calls of flying bats illustrates this point. A total of 17 species of bats was sampled. Fourteen bat species were captured and the echolocation calls of 12 species were recorded, three of them not revealed by mist nets or...

Climate change and Araucaria angustifolia Bert. O. Ktze conservation strategy. Repositório Alice
WREGE, M. S.; HIGA, R. C. V.; BRITEZ, R. M.; SOUSA, V. A. de; CARAMORI, P. H.; BRAGA, H. J.; RADIN, B..
Araucaria angustifolia, known as Parana pine, sets the boundary of the Ombrophylous Mixed Forest. Natural occurrence is above 500 m on the Brazilian Southern tableland and it has been related to climatic fluctuation during the Quaternary. The species was intensively exploited for timber use and due to the expansion of the area for agricultural use. The bioma conservation status is considered critical and only a restricted area is left on an advanced successional stage. The majority of the remaining area is under considerable pressure because it is located on the most populated areas. Besides human pressure, the species is also threatened by recent global climate change. It is a threat to some protected sites that can be decimated in a nearby future. The...

Different slopes of a mountain can determine the structure of ferns and lycophytes communities in a tropical forest of Brazil Anais da ABC (AABC)
NETTESHEIM,FELIPE C.; DAMASCENO,ELAINE R.; SYLVESTRE,LANA S..
A community of Ferns and Lycophytes was investigated by comparing the occurrence of species on different slopes of a paleoisland in Southeastern Brazil. Our goal was to evaluate the hypothesis that slopes with different geographic orientations determine a differentiation of Atlantic Forest ferns and lycophytes community. We recorded these plants at slopes turned towards the continent and at slopes turned towards the open sea. Analysis consisted of a preliminary assessment on fern beta diversity, a Non Metric Multidimensional Scaling (NMDS) and a Student t-test to confirm if sites sampling units ordination was different at each axis. We further used the Pearson coefficient to relate fern species to the differentiation pattern and again Student's t-test to...

Fine root biomass and root length density in a lowland and a montane tropical rain forest, SP, Brazil Biota Neotropica
Rosado,Bruno Henrique Pimentel; Martins,Amanda Cristina; Colomeu,Talita Cristina; Oliveira,Rafael Silva; Joly,Carlos Alfredo; Aidar,Marcos Pereira Marinho.
Fine roots, <2 mm in diameter, are responsible for water and nutrient uptake and therefore have a central role in carbon, nutrient and water cycling at the plant and ecosystem level. The root length density (RLD), fine root biomass (FRB) and vertical fine root distribution (VRD) in the soil profile have been used as good descriptors of resource-use efficiency and carbon storage in the soil. Along altitudinal gradients, decreases in temperature and radiation inputs (depending on the frequency of fog events) may reduce decomposition rates and nutrient availability what might stimulate plants to invest in fine roots, increasing acquisition of resources. We evaluated the seasonal variation of fine root parameters in a Lowland and Montane forest at the...

Genetic structure of natural populations of Cryptocarya moschata Nees (Lauraceae) from southeastern Brazilian Atlantic rain forest Biota Neotropica
Moraes,Pedro Luís Rodrigues de; Derbyshire,Maria Teresa Vitral de Carvalho.
This study was accomplished on a more comprehensive basis to evaluate previous questions that were raised from a preliminary article about the genetic structure of Cryptocarya moschata populations. Thus, through the analysis of 40 polymorphic allozyme loci, allele frequencies were estimated from 335 individuals of 11 natural populations of C. moschata from six hydrographic basins of São Paulo state and Serra da Estrela, Rio de Janeiro, Brazil. Estimates of Wright's F statistics were done through the analysis of variance, presenting average values of <img border=0 width=32 height=32 id="_x0000_i1026" src="../../../../../../img/revistas/bn/v4n1/img/a04car(f).jpg" align=absmiddle > or = 0.352, <img border=0 width=32 height=32 id="_x0000_i1027"...

Influence of environmental variation on Atlantic Forest tree-shrub-layer phytogeography in southeast Brazil Acta Botanica
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...

Species composition and biogeographic relations of the rock outcrop flora on the high plateau of Itatiaia, SE-Brazil Rev. Bras. Bot.
Ribeiro,Kátia Torres; Medina,Branca Maria Opazo; Scarano,Fabio Rubio.
We studied the flora of vegetation islands on rock outcrops on the Itatiaia Plateau (22°21'S and 44°40'W), at 2,400 m.a.s.l. A total of 114 vascular plant species, which correspond to ca. 20%-25% of the currently inventoried flora of the plateau, were sampled in 197 small vegetation islands (total area of 0.034 ha). Xerophytes and hydrophytes were often found side by side due to environmental heterogeneity at a small scale, explaining in part the high species diversity. Rock outcrops may support floras quite distinct from those in neighbouring habitats, due to the action of strong environmental filters, but in Itatiaia the geographic distribution patterns among rupicolous plants appear to mimic those described for the whole flora around it, with 15.1% of...
