Data from: Resources alter the structure and increase stochasticity in bromeliad microfauna communities

Jana S. Petermann, Pavel Kratina, Nicolas A. C. Marino, A. Andrew M. MacDonald, Diane S. Srivastava & Nicholas A. C. Marino
Although stochastic and deterministic processes have been found to jointly shape structure of natural communities, the relative importance of both forces may vary across different environmental conditions and across levels of biological organization. We tested the effects of abiotic environmental conditions, altered trophic interactions and dispersal limitation on the structure of aquatic microfauna communities in Costa Rican tank bromeliads. Our approach combined natural gradients in environmental conditions with experimental manipulations of bottom-up interactions (resources), top-down...

Data from: Cellular basis of morphological variation and temperature-related plasticity in Drosophila melanogaster strains with divergent wing shapes

Libéria Souza Torquato, Daniel Mattos, Bruna Palma Matta & Blanche Christine Bitner-Mathé
Organ shape evolves through cross-generational changes in developmental patterns at cellular and/or tissue levels that ultimately alter tissue dimensions and final adult proportions. Here, we investigated the cellular basis of an artificially selected divergence in the outline shape of Drosophila melanogaster wings, by comparing flies with elongated or rounded wing shapes but with remarkably similar wing sizes. We also tested whether cellular plasticity in response to developmental temperature was altered by such selection. Results show...

Data from: Atolchelys lepida, a new side-necked turtle from the Early Cretaceous of Brazil and the age of crown Pleurodira

Pedro S. R. Romano, Valéria Gallo, Renato R. C. Ramos & Luzia Antonioli
We report a new pleurodiran turtle from the Barremian Morro do Chaves Formation, Sergipe-Alagoas Basin, Brazil. We tested the phylogenetic position of Atolchelys lepida gen. et sp. nov. by including it in a comprehensive cladistic analysis of pleurodires. The new species is a basal member of Bothremydidae and simultaneously the oldest unambiguous crown Pleurodira. The biogeographic and chronostratigraphic significance of the finding has implications for the calibration of molecular clocks studies by pushing back the...

Data from: In silico phylogenomics using complete genomes: a case study on the evolution of hominoids

Igor Rodrigues Costa, Francisco Prosdocimi & W. Bryan Jennings
The increasing availability of complete genome data is facilitating the acquisition of phylogenomic datasets, but the process of obtaining orthologous sequences from other genomes and assembling multiple sequence alignments remains piecemeal and arduous. We designed software that performs these tasks and outputs anonymous loci (AL) or anchor loci (AE/UCE) datasets in ready-to-analyze formats. We demonstrate our program by applying it to the hominoids. Starting with human, chimpanzee, gorilla, and orangutan genomes, our software generated an...

Data from: Is there a correlation between abundance and environmental suitability derived from ecological niche modelling? A meta-analysis

Marcelo M. Weber, Richard D. Stevens, José Alexandre F. Diniz-Filho & Carlos Eduardo V. Grelle
It is thought that species abundance is correlated with environmental suitability and that environmental variables, scale, and type of model fitting can confound this relationship. We performed a meta-analysis to (i) test whether species abundance is positively correlated with environmental suitability derived from correlative ecological niche models (ENM), (ii) test whether studies encompassing large areas within a species range (>50%) exhibited higher AS correlations than studies encompassing small areas within a species range (<50%), (iii)...

Data from: A global meta-analysis on the ecological drivers of forest restoration success

Renato Crouzeilles, Michael Curran, Mariana S. Ferreira, David B. Lindenmayer, Carlos E. V. Grelle & José M. Rey Benayas
Two billion ha have been identified globally for forest restoration. Our meta-analysis encompassing 221 study landscapes worldwide reveals forest restoration enhances biodiversity by 15–84% and vegetation structure by 36–77%, compared with degraded ecosystems. For the first time, we identify the main ecological drivers of forest restoration success (defined as a return to a reference condition, that is, old-growth forest) at both the local and landscape scale. These are as follows: the time elapsed since restoration...

Data from: On the scaling of activity in tropical forest mammals

Bruno Cid, Chris Carbone, Fernado Fernadez, Patrick A. Jansen, Marcus Rowcliffe, Timothy O'Brien, Emmanuel Akampurira, Robert Bitariho, Santiago Espinosa, Krishna Gajapersad, Thiago Rocha Dos Santos, André Gonçalves, Margaret Kinnaird, Marcela Lima, Emanuel Martin, Badru Mugerwa, Francesco Rovero, Julia Salvador, Fernanda Santos, Wilson Spironello, Soraya Wijntuin & Luiz Gustavo Rodrigues Oliveira-Santos
Activity range – the amount of time spent active per day – is a fundamental aspect contributing to the optimization process by which animals achieve energetic balance. Based on their size and the nature of their diet, theoretical expectations are that larger carnivores need more time active to fulfil their energetic needs than do smaller ones and also more time active than similar-sized non-carnivores. Despite the relationship between daily activity, individual range and energy acquisition,...

Data from: On the relative importance of CSR ecological strategies and integrative traits to explain species dominance at local scales

Bruno H. P. Rosado & Eduardo A. De Mattos
PLEASE NOTE, PART OF THESE DATA ARE ALSO REFERRED TO ANOTHER ARTICLE. PLEASE SEE http://dx.doi.org/10.1111/j.1654-1103.2009.01119.x FOR MORE INFORMATION. 1. Identifying ecological strategies based on functional traits has been one of the main focuses of studies on plant community assembly. Recently, an important and timely tool, “StrateFy”, has been proposed for detecting plant strategies across the globe according to the CSR scheme. The CSR scheme is undeniably efficient across scales, and distinct CSR strategies among species...

Species identity and diversity effects on invasion resistance of tropical freshwater plant communities

Antonella Petruzzella, Tauany A. Da S. S. R. Rodrigues, Casper H. A. Van Leeuwen, Francisco De Assis Esteves, Marcos Paulo Figueiredo-Barros & Elisabeth S. Bakker
Biotic resistance mediated by native plant diversity has long been hypothesized to reduce the success of invading plant species in terrestrial systems in temperate regions. However, still little is known about the mechanisms driving invasion patterns in other biomes or latitudes. We help to fill this gap by investigating how native plant community presence and diversity, and the presence of native phylogenetically closely related species to an invader, would affect invader Hydrilla verticillata establishment success...

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....

Methicillin-resistant Staphylococcus aureus from infected skin lesions present several virulence genes and are associated with the CC30 in Brazilian children with atopic dermatitis

Fernanda Sampaio Cavalcante, Simone Saintive, Dennis Carvalho Ferreira, Adriana Barbosa Rocha Silva, Lorrayne Cardoso Guimarães, Beatriz Stofel Braga, Eliane de Dios Abad, Marcia Ribeiro & Kátia Regina Netto dos Santos
Atopic dermatitis (AD) is a chronic inflammatory skin disease and colonization by Staphylococcus aureus may affect up to 100% of these patients. Virulent and resistant isolates can worsen AD patient clinical condition and jeopardize the treatment. We aimed to detect virulence genes and to evaluate the biofilm production of S. aureus isolates from infected skin lesions of children with AD. Methicillin resistance was detected by phenotypic and molecular tests and the virulence genes were detected...

Does stress mess with rodents’ heads? Influence of habitat availability and genetic factors in mandible fluctuating asymmetry (FA) in South American water rats (Nectomys squamipes, Sigmodontinae) from Brazilian Atlantic rainforest remnants

Aldo Caccavo, Hudson Lemos, Luana Maroja & Pablo Gonçalves
Loss of developmental stability can lead to deviations from bilateral symmetry (i.e. Fluctuating Asymmetry -FA), and is thought to be caused by environmental and genetic factors associated with habitat loss and stress. Therefore, levels of FA might be a valuable tool to monitor wild populations if FA serves an indicator of exposure to stress due to impacts of habitat loss and fragmentation. In studies examining FA and habitat fragmentation, FA levels are often explained by...

Searching for drug leads targeted to the hydrophobic cleft of dengue virus capsid protein

Liliane O. Ortlieb, Ícaro P. Caruso, Nathane C. Mebus-Antunes, Andrea T. Da Poian, Elaine da C. Petronilho, José Daniel Figueroa-Villar, Claudia J. Nascimento & Fabio C. L. Almeida
We synthesised and screened 18 aromatic derivatives of guanylhydrazones and oximes aromatic for their capacity to bind to dengue virus capsid protein (DENVC). The intended therapeutic target was the hydrophobic cleft of DENVC, which is a region responsible for its anchoring in lipid droplets in the infected cells. The inhibition of this process completely suppresses virus infectivity. Using NMR, we describe five compounds able to bind to the α1-α2 interface in the hydrophobic cleft. Saturation...

Data from: Ontogeny and evolution of the elasmosaurid neck highlight a greater diversity of Antarctic plesiosaurians

Arthur S. Brum, Tiago R. Simões, Geovane A. Souza, André E. P. Pinheiro, Rodrigo G. Figueiredo, Michael W. Caldwell, Juliana M. Sayão & Alexander W. A. Kellner
The Antarctic plesiosaurian record is critical for understanding the evolution of elasmosaurids in the southern hemisphere. Elasmosaurids exhibit some of the most remarkable modifications of the vertebrate axial skeleton given their extreme elongation of the cervical region. Despite a considerable amount of information available on vertebral counts within Plesiosauria throughout the decades, we have a considerably more limited understanding of the diversity of cervical vertebral shapes in elasmosaurids and how these have changed throughout ontogeny...

Movement, translocation and MRR data for Heliconius butterflies

Priscila A. Moura, Gilberto Corso, Stephen H. Montgomery & Márcio Z. Cardoso
Site fidelity plays an important role in increasing foraging efficiency, particularly when food resources are reliable. In insects, site fidelity has largely been studied in Hymenopteran species, which consistently return to their nest site after foraging bouts. In butterflies, evidence of foraging site fidelity are limited but may be present in species with specific foraging specialisations, such as Heliconius, which have a derived foraging behaviour centred around active pollen feeding. Unlike many Hymenoptera, Heliconius are...

Pharmacogenetics of HIV therapy: State of the art in Latin American countries

Camila de Almeida Velozo, Flávia Rachel Moreira Lamarão, Lucia Elena Alvarado-Arnez & Cynthia Chester Cardoso
Abstract The use of combined antiretroviral therapy (cART) has resulted in a remarkable reduction in morbidity and mortality of people living with HIV worldwide. Nevertheless, interindividual variations in drug response often impose a challenge to cART effectiveness. Although personalized therapeutic regimens may help overcome incidence of adverse reactions and therapeutic failure attributed to host factors, pharmacogenetic studies are often restricted to a few populations. Latin American countries accounted for 2.1 million people living with HIV...

Feasibility of dried blood spot for hepatitis C diagnosis in vulnerable subjects and people living in remote areas from Brazil

Livia Melo Villar, Marjorie Parra de Lima, Helena Medina Cruz, Vanessa Salete de Paula, Leticia de Paula Scalioni, Geane Lopes Flores, Filipe Anibal Carvalho-Costa, Cynara Carvalho Parente, Maria Rosangela Cunha Duarte Coelho, Ana Cecilia Cavalcanti de Albuquerque, Flavio Augusto Pádua Milagres, Marcelo Santos Cruz, Tarcisio Matos Andrade, Ana Rita Coimbra Motta-Castro, Jurema Corrêa da Mota, Lia Laura Lewis-Ximenez & Francisco Inácio Bastos
Abstract Background Agile, accessible and cheap diagnosis of hepatitis C virus (HCV) infection is essential to achieve the elimination of this infection, worldwide, as mandated by the World Health Organzation as part of its strategy for 2030. Dried blood spots (DBS) can be an attractive alternative for sample collection among people living in remote areas and vulnerable populations due to the less invasive collection, its biosafety, and storage & transportation of samples at room temperature....

Social learning data in a foraging setting for Heliconius erato

Priscila Moura, Marcio Cardoso & Stephen Montgomery
Insects may acquire social information by active communication and through inadvertent social cues. In a foraging setting, the latter may indicate the presence and quality of resources. Although social learning in foraging contexts is prevalent in eusocial species, this behaviour has been hypothesised to also exist between conspecifics in non-social species with sophisticated behaviours, including Heliconius butterflies. Heliconius are the only butterfly genus with active pollen feeding, a dietary innovation associated with a specialised, spatially...
