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...

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: 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...

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...

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...

Modeling Dynamic Ideological Behavior in Political Networks

Carlos Henrique Gomes Ferreira, Fabricio Murai Ferreira, Breno de Souza Matos & Jussara Marques de Almeida
In this article, we model and analyze the dynamic behavior of political networks, both at the individual (party member) and ideological community levels. Our study relies on public data covering 15 years of voting sessions of the House of Representatives of two diverse party system, namely, Brazil and the United States. Whereas the former is an example of a highly fragmented party system, the latter illustrates the case of a highly polarized and non-fragmented system....

Data from: Genetic evaluation of migratory fish: implications for conservation and stocking programs

Juliana Pimentel, Sandra Ludwig, Leonardo Resende, Pedro Brandão-Dias, Adriana Pereira, Nazaré Abreu, Izinara Rosse, Ana Paula Martins, Susanne Facchin, João Lopes, Gilmar Santos, Carlos Alves & Evanguedes Kalapothakis
Fish stocking programs have been implemented to mitigate the blockage of original riverbeds by the construction of hydropower dams, which affects the natural migration of fish populations. However, this method raises concerns regarding the genetic rescue of the original populations of migratory fish species. We present the first study to investigate the genetic diversity, population structure, and gene flow (migration) of the Neotropical migratory fish Prochilodus costatus in the Três Marias dam in São Francisco...

Social Solidarity and the Ontological Foundations of Exclusionary Nationalism

C. J. Eland & Nicole L. M. T. de Pontes
This paper seeks to explore the dynamics of contemporary authoritarian populism from a historical perspective, relying on the approaches of Durkheim’s experimental sociology and Levinas’s ethical phenomenology. By reading the works of these two thinkers in concert, a pathology is exposed within this particular form of politics in that the State must necessarily close itself off to the critique of exteriority. Our reading of Durkheim explores the social pathology of nationalism while our reading of...

Data from: Spatiotemporal dynamics of the ant community in a dry forest differ by vertical strata but not by successional stage

Frederico Neves, Reuber Antoniazzi, Flávio Camarota, Fábio Pacelhe & Scott Powell
Ants are diverse and ecologically important organisms in tropical forests, where their spatiotemporal distribution can be highly complex. This complexity arises mainly from marked differences in microclimatic conditions and resource availability through space and time that is even more evident in highly seasonal environments, such as tropical dry forests. However, it is unclear how seasonality interacts with other factors that might shape temporal variation of ant composition (β-diversity), like vertical strata and habitat disturbance. Our...

Climate and plant structure determine the spatiotemporal butterfly distribution in a tropical mountain

Marina Beirão, Frederico S Neves & G Wilson Fernandes
Mountains are among the most powerful natural gradients for testing ecological and evolutionary responses of biota to environmental influences because differences in climate and plant structure occur over short spatial scales. We describe the spatiotemporal distribution patterns and drives of fruit-feeding butterfly diversity on the mountaineous region of Serra do Cipó, Minas Gerais, Brazil. Seven elevations from 822 to 1388 m were selected for evaluating the effects of abiotic factors and vegetation characteristics on butterfly...

Weather effects on nestling survival of great tits vary according to the developmental stage

Fernando Marques-Santos & Niels J. Dingemanse
Organisms change breeding investments as a function of the environment, thereby maximizing reproductive success. Climate change studies of avian life-history have long focused on plasticity of laying dates and clutch sizes in response to weather conditions prior to clutch initiation. By contrast, effects of unpredictable weather events occurring after initial reproductive decisions are made have largely been ignored, despite becoming increasingly important with ongoing climate change. We studied the detrimental effects of fluctuations in temperature...

Sex affects immunolabeling for histone 3 K27me3 in the trophectoderm of the bovine blastocyst but not labeling for histone 3 K18ac

Peter Hansen, Luciano Carvalheira, Paula Tribulo & Alan Borges
The mammalian embryo displays sexual dimorphism in the preimplantation period. Moreover, competence of the embryo to develop is dependent on the sire from which the embryo is derived and can be modified by embryokines produced by the endometrium such as colony stimulating factor 2 (CSF2). The preimplantation period is characterized by large changes in epigenetic modifications of DNA and histones. It is possible, therefore, that effects of sex, sire, and embryo regulatory molecules are mediated...

Sales, Erika R. Manuli, Julien Thézé, Luiz Almeida, Mariane T. Menezes, Carolina M. Voloch, Marcilio J. Fumagalli, Thaís M. Coletti, Camila A. M. Da Silva, Mariana S. Ramundo, Mariene R. Amorim, Henrique H. Hoeltgebaum, Swapnil Mishra, Mandev S. Gill, Luiz M. Carvalho, Lewis F. Buss … & Nuno R. Faria
Brazil currently has one of the fastest growing SARS-CoV-2 epidemics in the world. Owing to limited available data, assessments of the impact of non-pharmaceutical interventions (NPIs) on virus spread remain challenging. Using a mobility-driven transmission model, we show that NPIs reduced the reproduction number from >3 to 1–1.6 in São Paulo and Rio de Janeiro. Sequencing of 427 new genomes and analysis of a geographically representative genomic dataset identified >100 international virus introductions in Brazil....

The challenges to plan and develop pedagogical practices involving digital written culture in childhood education

Mônica Daisy Vieira Araújo, Isabel Cristina Alves da Silva FRADE & Julianna Silva Glória
Nowadays children are part of the digital culture (Cassany, 2002), using its supports and involving themselves in different uses of digital written culture (Chartier, 2011, 2016). Are teachers considering these uses in preschools? How can we create teaching proposals that attend the learning conditions of young children? How do children deal with the devices, languages, and the particular uses of digital written culture? This text aims to reflect on the processes to incorporate digital technologies...

Anatomical partitioning has little influence in topologies from Bayesian phylogenetic analyses of morphological data

Daniel Casali, Felipe Freitas & Fernando Perini
Morphological data is a fundamental source of evidence to reconstruct the Tree of Life, and Bayesian phylogenetic methods are increasingly being used for this task, along with, or instead of, traditional parsimony approaches. Bayesian phylogenetic analyses require the use of proper evolutionary models and their performance have been intensively studied in the past few years, with significant improvements to our knowledge regarding their performance. Notwithstanding, it was only recently that partitioned models for morphology received...
