O êxtase do povo: P.M. (Cuba, 1961) e Arrasta a bandeira colorida (Brasil, 1970)

Victor Guimarães
O artigo traça uma comparação figurativa entre P.M. (Sabá Cabrera Infante & Orlando Jiménez Leal, Cuba, 1961) e Arrasta a bandeira colorida (Aloysio Raulino & Luna Alkalay, Brasil, 1970), no sentido de interrogar como a figuração do povo no cinema latino-americano é atravessada pela experiência histórica.

Data from: Changes in tree and liana communities along a successional gradient in a tropical dry forest in south-eastern Brazil

Yule Roberta Ferreira Nunes, Mario Marcos Espirito-Santo, Giovana Rodrigues Da Luz, Maria Das Dores Magalhaes Veloso, Rubens Manuel Dos Santos, Sofia Calvo-Alvarado, Sandra Milena Duran, Santos D'Ângelo Neto, Bruno G. Madeira, G. Wilson Fernandes & G. Arturo Sánchez Azofeifa
We investigated changes in species composition and structure of tree and liana communities along a successional gradient in a seasonally dry tropical forest. There was a progressive increase in tree richness and all tree structural traits from early to late stages, as well as marked changes in tree species composition and dominance. This pattern is probably related to pasture management practices such as ploughing, which remove tree roots and preclude regeneration by resprouting. On the...

Data from: Bioacoustics reveals two new syntopic species of Adenomera Steindachner (Anura: Leptodactylidae: Leptodactylinae) in the Cerrado of central Brazil

Thiago Ribeiro De Carvalho & Ariovaldo Antonio Giaretta
In this paper, we describe two syntopic species of Adenomera from the Chapada dos Veadeiros microregion, northern State of Goiás, central Brazil, recognized based on morphology, color patterns, and bioacoustics. Specimens and calls were obtained in the Municipality of Teresina de Goiás, central Brazil. Adenomera cotuba sp. nov. is diagnosed from the other 16 congeneric species by its 1) small size (adult male SVL 18.6–20.5 mm) and very robust body; 2) dorsum glandular/granular with no...

Data from: Searching for keystone plant resources in fruit-frugivore interaction networks across the Neotropics

João Vitor De S. Messeder, Tadeu J. Guerra, Wesley Dáttilo & Fernando A. O. Silveira
Identifying keystone plant resources (KPR) is a contentious issue in ecology and conservation. Despite recent advances provided by mutualistic networks, we still lack studies addressing large-scale identification of keystone plants. We developed a novel quantitative framework for the large-scale identification of KPR that combines centrality and effects of simulated removals on networks properties. We built a database with 38 fruit-frugivore networks comprising 6180 pairwise interactions from Neotropical forest and non-forest ecosystems ranging from sea level...

New set of microsatellite markers for the great-billed seed-finch (Sporophila maximiliani – Passeriformes: Thraupidae): tools for inspection and conservation

Amanda De Melo, Evanguedes Kalapothakis, Sandra Ludwig, Luiz Alfredo Baptista, Mariana Lara, Leo Silva & Mariana Telles
The Thraupidae family is one of the most wanted by bird breeders in Brazil due to its diverse, colorful and melodious singers as representatives. The Great-billed Seed-finch, Sporophila maximiliani, is the only representative of the genus Sporophila considered critically endangered in Brazil. Due to the demands of environmental agencies and of conservation programs, there is a need to increase the number of molecular markers available for the genus and specially for S.maximiliani. Therefore, this work...

Jesper Sonne, Jeferson Vizentin-Bugoni, Pietro K. Maruyama, Andréa C. Araújo, Edgar Chávez-González, Aline G. Coelho, Peter A. Cotton, Oscar H. Marín-Gómez, Carlos Lara, Liliana R. Lasprilla, Caio G. Machado, Maria A. Maglianesi, Tiago S. Malucelli, Ana M. Martín-González, Genilda M. Oliveira, Paulo E. Oliveira, Raul Ortiz-Pulido, Márcia A. Rocca, Licléia C. Rodrigues, Ivan Sazima, Benno I. Simmons, Boris Tinoco, Isabela G. Varassin, Marcelo F. Vasconcelos, Bob O’Hara … & Bo Dalsgaard
Interactions between species are influenced by different ecological mechanisms, such as morphological matching, phenological overlap, and species abundances. How these mechanisms explain interaction frequencies across environmental gradients remains poorly understood. Consequently, we also know little about the mechanisms that drive the geographical patterns in network structure, such as complementary specialization and modularity. Here, we use data on morphologies, phenologies and abundances to explain interaction frequencies between hummingbirds and plants at a large geographic scale. For...

Data from: Abundance drives broad patterns of generalisation in plant-hummingbird pollination networks

Benno I. Simmons, Jeferson Vizentin-Bugoni, Pietro K. Maruyama, Peter A. Cotton, Oscar H. Marín-Gómez, Carlos Lara, Liliana Rosero-Lasprilla, María A Maglianesi, Raúl Ortiz-Pulido, Márcia A. Rocca, Licléia C. Rodrigues, Boris Tinocco, Marcelo F. Vasconcelos, Marlies Sazima, Ana M. Martín González, Jesper Sonne, Carsten Rahbek, Lynn V. Dicks, Bo Dalsgaard & William J. Sutherland
Abundant pollinators are often more generalised than rare pollinators. This could be because abundant species have more chance encounters with potential interaction partners. On the other hand, generalised species could have a competitive advantage over specialists, leading to higher abundance. Determining the direction of the abundance-generalisation relationship is therefore a ‘chicken-and-egg’ dilemma. Here we determine the direction of the relationship between abundance and generalisation in plant-hummingbird pollination networks across the Americas. We find evidence that...

Pablo A.S. Fonseca, Thiago P. Leal, Fernanda Caroline Santos, Mateus Henrique Gouveia, Samir Id-Lahoucine, Izinara C. Rosse, Ricardo V. Ventura, Frank Angelo T. Bruneli, Marco Antônio Machado, Maria Gabriela C.D. Peixoto, Eduardo Tarazona-Santos, Maria Raquel S. Carvalho & Pablo A. S. Fonseca
Cryptic relatedness is a confounding factor in genetic diversity and genetic association studies. Development of strategies to reduce cryptic relatedness in a sample is a crucial step for downstream genetic analyzes. The present study uses a node selection algorithm, based on network degrees of centrality, to evaluate its applicability and impact on evaluation of genetic diversity and population stratification. 1,036 Guzerá (Bos indicus) females were genotyped using Illumina Bovine SNP50 v2 BeadChip. Four strategies were...

Data from: Subtle changes in elevation shift bat-assemblage structure in Central Amazonia

, Lucas Gabriel Do Amaral Pereirab, Valéria Da Cunha Tavaresc, William E. Magnussond, Fabricio Beggiato Baccaroe & Paulo Estefano D. Bobrowiec
The distribution patterns of animal species at local scales have been explained by direct influences of vegetation structure, topography, food distribution and availability. However, these variables can also interact and operate indirectly on the distribution of species. Here, we examined the direct and indirect effects of food availability (fruits and insects), vegetation clutter and elevation in structuring phyllostomid-bat assemblages in a continuous terra firme forest in Central Amazonia. Bats were captured in 49 plots over...

Data from: Disentangling the pathways of land use impacts on the functional structure of fish assemblages in Amazon streams

Rafael P. Leitão, Jansen Zuanon, David Mouillot, Cecília G. Leal, Robert M. Hughes, Philip R. Kaufmann, Sébastien Villéger, Paulo S. Pompeu, Daniele Kasper, Felipe R. De Paula, Silvio F. B. Ferraz & Toby A. Gardner
Agricultural land use is a primary driver of environmental impacts on streams. However, the causal processes that shape these impacts operate through multiple pathways and at several spatial scales. This complexity undermines the development of more effective management approaches, and illustrates the need for more in-depth studies to assess the mechanisms that determine changes in stream biodiversity. Here we present results of the most comprehensive multi-scale assessment of the biological condition of streams in the...

Data from: Deconstructing species richness–environment relationships in Neotropical lianas

Leila Meyer, W. Daniel Kissling, Lucia G. Lohmann, Joaquín Hortal & José A. F. Diniz-Filho
Abstract Aim: Studying species richness patterns by considering all species as equivalent units may prevent a deeper understanding of the origin and maintenance of biodiversity. Here, we deconstructed the species richness of Neotropical lianas by specific attributes of species to study richness–environment relationships. Location: Neotropics Taxon: Tribe Bignonieae (Bignoniaceae), the largest clade of Neotropical lianas Methods: We used five morphological, one geographical and two evolutionary attributes of species, each with 2–7 attribute states. We compared...

Data from: Disentangling the factors that shape bromeliad and ant communities in the canopies of cocoa agroforestry and preserved Atlantic Forest

Reuber Antoniazzi, Wesley DaRocha, Jacques Delabie, Götz Schroth, Geraldo Fernandes & Frederico Neves
In tropical forest canopies, host tree characteristics shape epiphyte communities, and both host tree characteristics and epiphytes determine invertebrate communities, e.g., ants. Tree height is among the factors most often mentioned as a strong predictor for both bromeliad and ant communities. However, many factors interact dynamically in shaping the tree-bromeliad-ant association. Here, we investigated the effects of the host tree and canopy structural characteristics on both bromeliads and ants. We sampled bromeliads on 180 trees...

Abstract Background Chikungunya virus (CHIKV) emerged in the Americas in 2013 and has caused ~2.1 million cases and over 600 deaths. A retrospective investigation was undertaken to describe clinical, epidemiological and virus genomic features associated with deaths caused by CHIKV in Ceará state, northeast Brazil. Methods Sera, cerebrospinal fluid (CSF) and tissue samples from 100 fatal cases with suspected arbovirus infection were tested for CHIKV, dengue (DENV) and Zika virus (ZIKV). Clinical, epidemiological and death...

SNP dataset for Buchenavia oxycarpa

Alison Nazareno
Wallace’s (1854) Riverine Barrier hypothesis is one of the earliest explanations for Amazon biotic diversification. Despite the importance of this hypothesis for explaining speciation in some animal groups, it has not been studied extensively for plant species. In this study we use a prominent Amazon tree, Buchenavia oxycarpa (Mart.) Eichler (Combretaceae), to evaluate Wallace’s hypothesis along the Rio Negro, a major Amazon tributary that has driven allopatric speciation for several animal taxa. We sampled six...

Opposite latitudinal patterns for bird and arthropod predation revealed in the experiments with differently colored artificial prey

Elena Zvereva, Bastien Castagneyrol, Tatiana Cornelissen, Anders Forsman, Juan Antonio Hernández-Agüero, Tero Klemola, Lucas Paolucci, Vicente Polo, Norma Salinas, K. Jurie Theron, Guorui Xu, Vitali Zverev & Mikhail Kozlov
The strength of biotic interactions is generally thought to increase towards the equator, but support for this hypothesis is contradictory. We explored whether predator attacks on artificial prey of eight different colours vary among climates and whether this variation affects the detection of latitudinal patterns in predation. The data set provides number of damage marks on each of 1320 plasticine caterpillars of eight different colours, which were attached to branches of woody plants and exposed...

Data from: Females of a solitary bee reject males to collect food for offspring

Ana Laura Dutra, Clemens Schlindwein & Reisla Oliveira
The time dedicated to courtship and copulation is the most general cost of mating for females. However, quantitative estimates of this cost and the consequences for female mating behavior have been investigated for only a few model organisms, and mostly under laboratory conditions. We determined the costs of copulations and persistent courtship by males in terms of time for females of the solitary bee Anthrenoides micans. We estimated the rate and duration of male mating...

Data from: Assessing the conservation value of secondary savanna for large mammals in the Brazilian Cerrado

Guilherme B. Ferreira, Jorge A. Ahumada, Marcelo J. R. Oliveira, Fernando F. De Pinho, Izabela M. Barata, Chris Carbone & Ben Collen
Debate about the conservation value of secondary habitats has tended to focus on tropical forests, increasingly recognizing the role of secondary forests for biodiversity conservation. However, there remains a lack of information about the conservation value of secondary savannas. Here, we conducted a camera trap survey to assess the effect of secondary vegetation on large mammals in a Brazilian Cerrado protected area, using a single-season occupancy framework to investigate the response of individual species (species-level...

Data from: Habitat attributes similarities reduce impacts of land-use conversion on seed removal

Ananza M. Rabello, Catherine L. Parr, Antônio C.M. Queiroz, Danielle L. Braga, Graziele S. Santiago & Carla R. Ribas
Changes in land use strongly influence habitat attributes (e.g., herbaceous ground cover and tree richness) and can consequently affect ecological functions. Most studies have focused on the response of these ecological functions to land-use changes within only a single vegetation type. These studies have often focused solely on agricultural conversion of forests, making it nearly impossible to draw general conclusions across other vegetation types or with other land use changes (e.g., afforestation). We examined the...

Data from: Biotic and abiotic variables influencing plant litter breakdown in streams: a global study

Luz Boyero, Richard Pearson, Cang Hui, Mark Gessner, Javier Perez, Markos Alexandrou, Manuel Graça, Bradley Cardinale, Ricardo Albariño, M. Arunachalam, Leon Barmuta, Andrew Boulton, Andreas Bruder, Marcos Callisto, Eric Chauvet, Russell Death, David Dudgeon, Andrea Encalada, Veronica Ferreira, Ricardo Figueroa, Alex Flecker, , Julie Helson, Tomoya Iwata, Tajang Jinggut … & Catherine Yule
Plant litter breakdown is a key ecological process in terrestrial and freshwater ecosystems. Streams and rivers, in particular, have high rates of carbon dioxide evasion and they contribute substantially to global carbon fluxes. However, there is little information available on the relative roles of different drivers of plant litter breakdown in fresh waters, particularly at large scales. We present a global-scale study of litter breakdown in streams to compare the roles of biotic, climatic and...

Data from: Climatic drivers of leaf traits and genetic divergence in the tree Annona crassiflora: a broad spatial survey in the Brazilian savannas

Priciane C. Ribeiro, Matheus L. Souza, Larissa A. C. Muller, Vincenzo A. Ellis, Myriam Heuertz, José P. Lemos-Filho & Maria Bernadete Lovato
The Cerrado is the largest South American savanna and encompasses substantial species diversity and environmental variation. Nevertheless, little is known regarding the influence of the environment on population divergence of Cerrado species. Here, we searched for climatic drivers of genetic (nuclear microsatellites) and leaf trait divergence in Annona crassiflora, a widespread tree in the Cerrado. The sampling encompassed all phytogeographic provinces of the continuous area of the Cerrado and included 397 individuals belonging to 21...

Data from: Nuclear markers reveal a complex introgression pattern among marine turtle species on the Brazilian coast

Sibelle T. Vilaça, Sarah M. Vargas, Paula Lara-Ruiz, Érica Molfetti, Estéfane C. Reis, Gisele Lôbo-Hajdu, Luciano S. Soares & Fabrício R. Santos
A surprisingly high frequency of interspecific sea turtle hybrids have been previously recorded in a nesting site along a short stretch of the Brazilian coast. Mitochondrial DNA data indicated that as much as 43% of the females identified as E. imbricata are hybrids in this area (Bahia State of Brazil). It is a remarkable find, since most of the nesting sites surveyed worldwide, including some in northern Brazil, presents no hybrids, and rare Caribbean sites...

Beta diversity of aquatic macroinvertebrate assemblages associated with leaf patches in neotropical montane streams

Marcos Callisto, Marden Linares, , Robert Hughes, Marcelo Moretti, Diego Macedo & Ricardo Ribeiro De Castro Solar
Over 70% of the total channel length in all river basins is formed by low order streams, many of which originate on mountaintops. Headwater streams play fundamental roles in processing and transporting terrestrial and aquatic organic matter, often harboring high biodiversity in bottom leaf patches deposited from riparian vegetation. The objective of this study was to assess the variation in taxonomic composition (measured by beta diversity of aquatic macroinvertebrates) among stream sites located in the...
