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: 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: 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: 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: 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...

Darlan S. Candido, Ingra M. Claro, Jaqueline G. De Jesus, William M. Souza, Filipe R. R. Moreira, Simon Dellicour, Thomas A. Mellan, Louis Du Plessis, Rafael H. M. Pereira, Flavia C. S. 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....

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...

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,...

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...

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...

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...

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...

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...

Data from: Molecular phylogeny of Triatomini (Hemiptera: Reduviidae: Triatominae)

Silvia Andrade Justi, Claudia A. M. Russo, Jacenir Reis Dos Santos Mallet, Marcos Takashi Obara & Cleber Galvão
Background: The Triatomini and Rhodniini (Hemiptera: Reduviidae) tribes include the most diverse Chagas disease vectors; however, the phylogenetic relationships within the tribes remain obscure. This study provides the most comprehensive phylogeny of Triatomini reported to date. Methods: The relationships between all of the Triatomini genera and representatives of the three Rhodniini species groups were examined in a novel molecular phylogenetic analysis based on the following six molecular markers: the mitochondrial 16S; Cytochrome Oxidase I and...

Data from: A new species of Allophryne (Anura: Allophrynidae) from the Atlantic Rain Forest biome of eastern Brazil

Ulisses Caramaschi, Victor G. D. Orrico, Julián Faivovich, Iuri R. Dias & Mirco Solé
A new species of the genus Allophryne is described and, in contrast to its congeners that occur in the Amazon Basin, is based on specimens obtained in Uruçuca, State of Bahia, in the Atlantic Rain Forest of eastern Brazil. Allophryne relicta sp. nov. is characterized by a medium body size for the genus (snout–vent length range 19.9–21.9 mm in males); large head (head width about 35% of SVL); large, red-orange eyes, with a large black...

Data from: Revised classification and evolution of leucotrichiine microcaddisflies (Trichoptera: Hydroptilidae) based on morphological and molecular data

Allan P. M. Santos, Jorge L. Nessimian & Daniela M. Takiya
Hydroptilidae constitute the most diverse caddisfly family, with over 2000 species known from every habitable continent. Leucotrichiinae are exclusively New World microcaddisflies, currently including over 200 species and 17 genera. Phylogenetic analyses of Leucotrichiinae relationships based on 114 morphological characters and 2451 molecular characters from DNA sequences were conducted. DNA sequences analysed were from one mitochondrial gene, cytochrome oxidase I (653 bp), and four nuclear genes, carbamoylphosphate synthase (802 bp), elongation factor 1α (352 bp),...

Data from: Dynamics of coral reef benthic assemblages of the Abrolhos Bank, eastern Brazil: inferences on natural and anthropogenic drivers

Ronaldo B. Francini-Filho, Ericka O. C. Coni, Pedro M. Meirelles, Gilberto M. Amado-Filho, Fabiano L. Thompson, Guilherme H. Pereira-Filho, Alex C. Bastos, Douglas P. Abrantes, Camilo M. Ferreira, Fernando Z. Gibran, Arthur Z. Güth, Paulo Y. G. Sumida, Nara L. Oliveira, Les Kaufman, Carolina V. Minte-Vera & Rodrigo L. Moura
The Abrolhos Bank (eastern Brazil) encompasses the largest and richest coral reefs of the South Atlantic. Coral reef benthic assemblages of the region were monitored from 2003 to 2008. Two habitats (pinnacles’ tops and walls) were sampled per site with 3-10 sites sampled within different reef areas. Different methodologies were applied in two distinct sampling periods: 2003-2005 and 2006-2008. Spatial coverage and taxonomic resolution were lower in the former than in the latter period. Benthic...

Data from: The curious case of Hermodice carunculata (Annelida: Amphinomidae): evidence for genetic homogeneity throughout the Atlantic Ocean and adjacent basins

Joseph B. Ahrens, Elizabeth Borda, Rômulo Barroso, Paulo C. Paiva, Alexandra M. Campbell, Alexander Wolf, Maggy M. Nugues, Greg W. Rouse & Anja Schulze
Over the last few decades, advances in molecular techniques have led to the detection of strong geographic population structure and cryptic speciation in many benthic marine taxa, even those with long-lived pelagic larval stages. Polychaete annelids, in particular, generally show a high degree of population divergence, especially in mitochondrial genes. Rarely have molecular studies confirmed the presence of ‘cosmopolitan’ species. The amphinomid polychaete Hermodice carunculata was long considered the sole species within its genus, with...

Data from: Influence of salinity on bacterioplankton communities from the Brazilian rain forest to the coastal Atlantic Ocean

Cynthia B. Silveira, Ricardo P. Vieira, Alexander M. Cardoso, Rodolfo Paranhos, Rodolfo M Albano, Orlando B. Martins & Rodolpho M. Albano
BACKGROUND: Planktonic bacteria are recognized as important drivers of biogeochemical processes in all aquatic ecosystems, however, the taxa that make up these communities are poorly known. The aim of this study was to investigate bacterial communities in aquatic ecosystems at Ilha Grande, Rio de Janeiro, Brazil, a preserved insular environment of the Atlantic rain forest and how they correlate with a salinity gradient going from terrestrial aquatic habitats to the coastal Atlantic Ocean. METHODOLOGY/PRINCIPAL FINDINGS:...

Data from: Intraspecific genetic structure, divergence and high rates of clonality in an amphi-Atlantic starfish

Alex Garcia-Cisneros, Crue Palacín, Carlos Renato R. Ventura, Barbara Feital, Paulo C. Paiva & Rocio Perez Portela
Intraspecific genetic diversity and divergence have a large influence on the adaption and evolutionary potential of species. The widely distributed starfish, Coscinasterias tenuispina, combines sexual reproduction with asexual reproduction via fission. Here we analyse the phylogeography of this starfish to reveal historical and contemporary processes driving its intraspecific genetic divergence. We further consider whether asexual reproduction is the most important method of propagation throughout the distribution range of this species. Our study included 326 individuals...

Data from: Ecological restoration success is higher for natural regeneration than for active restoration in tropical forests

Renato Crouzeilles, Mariana S. Ferreira, Robin L. Chazdon, David B. Lindenmayer, Jerônimo B. B. Sansevero, Lara Monteiro, Alvaro Iribarrem, Agnieszka E. Latawiec & Bernardo B. N. Strassburg
Is active restoration the best approach to achieve ecological restoration success (the return to a reference condition, that is, old-growth forest) when compared to natural regeneration in tropical forests? Our meta-analysis of 133 studies demonstrated that natural regeneration surpasses active restoration in achieving tropical forest restoration success for all three biodiversity groups (plants, birds, and invertebrates) and five measures of vegetation structure (cover, density, litter, biomass, and height) tested. Restoration success for biodiversity and vegetation...

Data from: Metaproteomics reveals metabolic transitions between healthy and diseased stony coral Mussismilia braziliensis

Gizele D. Garcia, Eidy De O. Santos, Gabriele V. Sousa, Russolina B. Zingali, Cristiane C. Thompson & Fabiano L. Thompson
Infectious diseases such as white plague syndrome (WPS) and black band disease (BBD) have caused massive coral loss worldwide. We performed a metaproteomic study on the Abrolhos coral Mussismilia braziliensis to define the types of proteins expressed in healthy corals compared to WPS- and BBD-affected corals. A total of 6363 MS/MS spectra were identified as 361 different proteins. Healthy corals had a set of proteins that may be considered markers of holobiont homoeostasis, including tubulin,...

Species niches, not traits, determine abundance and occupancy patterns: a multi-site synthesis

Nicholas Marino, Régis Céréghino, Benjamin Glbert, Jana Petermann, Diane Srivastava, Paula De Omena, Fabiola Bautista, Laura Guzman, Gustavo Romero, Mark Trzcinski, Ignacio Barberis, Bruno Corbara, Vanderlei Debastiani, Olivier Dézerald, Pavel Kratina, Céline Leroy, Arthur Andrew MacDonald, Guillermo Montero, Valério Pillar, Barbara Richardson, Michael Riachardson, Stanislas Talaga, Ana Gonçalves, Gustavo Piccoli, Merlijn Jocque … & Vinicius Farjalla
Aim: Locally abundant species are usually widespread, and such pattern has been related to properties of the niches and traits of species. However, such explanations fail to account for the potential of traits to determine species niches, and often overlook statistical artifacts. Here we examine how trait distinctiveness determines species abilities to exploit either common habitats (niche position) or a range of habitats (niche breadth), and how niche position and breadth in turn affect abundance...
