Data from: Are there general laws for digit evolution in squamates? The loss and re-evolution of digits in a clade of fossorial lizards (Brachymeles, Scincinae)

Günter P. Wagner, Oliver W. Griffith, Philip J. Bergmann, Gaelle Bello-Hellegouarch, Tiana Kohlsdorf, Anjan Bhullar & Cameron D. Siler
Evolutionary simplification of autopodial structures is a major theme in studies of body‐form evolution. Previous studies on amniotes have supported Morse's law, that is, that the first digit reduced is Digit I, followed by Digit V. Furthermore, the question of reversibility for evolutionary digit loss and its implications for “Dollo's law” remains controversial. Here, we provide an analysis of limb and digit evolution for the skink genus Brachymeles. Employing phylogenetic, morphological, osteological, and myological data,...

Data from: An exceptionally preserved association of complete dinosaur skeletons reveals the oldest long-necked sauropodomorphs

Rodrigo Temp Müller, Max Cardoso Langer & Sérgio Dias-Da-Silva
The rise of sauropodomorphs is still poorly understood due to the scarcity of well-preserved fossils in early Norian rocks. Here, we present an association of complete and exceptionally well-preserved dinosaur skeletons that helps filling that gap. They represent a new species, which is recovered as member of a clade solely composed of Gondwanan Triassic taxa. The new species allows defining a set of anatomical changes that shaped sauropodomorph evolution along a period from 233–225 Ma,...

Data from: Increases in sampling support the southern Gondwanan hypothesis for the origin of dinosaurs

Júlio C. A. Marsola, Gabriel S. Ferreira, Max C. Langer, David J. Button & Richard J. Butler
Dinosaurs were ubiquitous in terrestrial ecosystems through most of the Mesozoic and are still diversely represented in the modern fauna in the form of birds. Recent efforts to better understand the origins of the group have resulted in the discovery of many new species of early dinosaurs and their closest relatives (dinosauromorphs). In addition, recent re-examinations of early dinosaur phylogeny have highlighted uncertainties regarding the interrelationships of the main dinosaur lineages (Sauropodomorpha, Theropoda and Ornithischia),...

Maga Gei, Danaë M. A. Rozendaal, Lourens Poorter, Frans Bongers, Janet I. Sprent, Mira D. Garner, T. Mitchell Aide, José Luis Andrade, Patricia Balvanera, Justin M. Becknell, Pedro H.S. Brancalion, George A. L. Cabral, Ricardo Gomes César, Robin L. Chazdon, Rebecca J. Cole, Gabriel Dalla Colletta, Ben De Jong, Julie S. Denslow, Daisy H. Dent, Saara J. DeWalt, Juan Manuel Dupuy, Sandra M. Durán, Mário Marcos Do Espírito Santo, G. Wilson Fernandes, Yule Roberta Ferreira Nunes … & Jennifer S. Powers
The nutrient demands of regrowing tropical forests are partly satisfied by nitrogen (N)-fixing legume trees, but our understanding of the abundance of those species is biased towards wet tropical regions. Here we show how the abundance of Leguminosae is affected by both recovery from disturbance and large-scale rainfall gradients through a synthesis of forest-inventory plots from a network of 42 Neotropical forest chronosequences. During the first three decades of natural forest regeneration, legume basal area...

Data from: The use of metabarcoding for meiofauna ecological patterns assessment

Laiza Cabral De Faria, Maikon Di Domenico, Sónia C. S. Andrade, Monique Cristina Dos Santos, Gustavo Fonseca, Joana Zanol & A. Cecilia Z. Amaral
Marine meiofauna comprises up to 22 phyla. Its morphological identification requires time and taxonomists' expertise, and molecular tools can make this task faster. We aim to disentangle meiofaunal diversity patterns at Araçá Bay by applying a model selection approach and estimating the effectiveness of metabarcoding (18S rDNA) and morphological methods for estimating the response of meiofauna diversity in small-scale interactions with environmental variables. A rarefaction curve indicated that ten samples were sufficient for estimating the...

Data from: Tangled banks: a landscape genomic evaluation of wallace's riverine barrier hypothesis for three amazon plant species

Alison G. Nazareno, Christopher W. Dick & Lúcia G. Lohmann
Wallace’s Riverine Barrier hypotheses is one of the earliest biogeographic explanations for Amazon speciation, but it has rarely been tested in plants. In this study, we used three woody Amazonian plant species to evaluate Wallace’s Hypothesis using tools of landscape genomics. We generated unlinked single-nucleotide polymorphism (SNP) data from the nuclear genomes of 234 individuals (78 for each plant species) across 13 sampling sites along the Rio Branco, Brazil, for Amphirrhox longifolia (8,075 SNPs), Psychotria...

Data from: Prevalence of sleep-disordered breathing after stroke and TIA: a meta-analysis

Andrea Seiler, Millene Camilo, Lyudmila Korostovtseva, Alan G. Haynes, Anne-Kathrin Brill, Thomas Horvath, Matthias Egger & Claudio L. Bassetti
Objective: To perform a systematic review and meta-analysis on the prevalence of sleep-disordered breathing (SDB) after stroke. Methods: We searched PubMed, Embase (Ovid), the Cochrane Library, and CINAHL (from their commencements to 7th of April 2017) for clinical studies reporting prevalence and/or severity of SDB after stroke or transitory ischemic attack (TIA). Only sleep apnea tests performed with full polysomnography and diagnostic devices of the AASM categories I-IV were included. We conducted random-effects meta-analysis. PROSPERO...

Data from: Multi-proxy evidence highlights a complex evolutionary legacy of maize in South America

Logan Kistler, S. Yoshi Maezumi, Jonas Gregorio De Souza, Natalia A. S. Przelomska, Flaviane Malaquias Costa, Oliver Smith, Hope Loiselle, Jazmín Ramos-Madrigal, Nathan Wales, Eduardo Rivail Ribeiro, Ryan R. Morrison, Claudia Grimaldo, Andre P. Prous, Bernardo Arriaza, M. Thomas P. Gilbert, Fabio De Oliveira Freitas & Robin G. Allaby
Domesticated maize evolved from wild teosinte under human influences in Mexico beginning around 9,000 BP, traversed Central America by ~7,500 BP, and spread into South America by ~6,500 BP. Landrace and archaeological maize genomes from South America suggest that the ancestral population to South American maize was brought out of the domestication center in Mexico and became isolated from the wild teosinte gene pool before traits of domesticated maize were fixed. Deeply structured lineages then...

Data from: How well can we estimate diversity dynamics for clades in diversity decline?

Gustavo Burin, Laura R.V. Alencar, Jonathan Chang, Michael E. Alfaro, Tiago B. Quental & Laura R V Alencar
The fossil record shows that the vast majority of all species that ever existed are extinct and that most lineages go through an expansion and decline in diversity. However, macroevolutionary analyses based upon molecular phylogenies have difficulty inferring extinction dynamics, raising questions about whether the neontological record can contribute to an understanding of the decline phenomenon. Two recently developed diversification methods for molecular phylogenies (RPANDA and BAMM) incorporate models that theoretically have the capacity to...

Data from: Landscape structure regulates pest control provided by ants in sun coffee farms

Natalia Aristizabal & Jean Paul Metzger
1. Ants play a fundamental role in coffee pest control. Despite this, there is a lack of understanding about how landscape configuration and composition regulate the ecosystem service provided by ants in sun coffee farms within highly fragmented landscapes. 2. We measured whether landscape structure influences ants’ ability to regulate coffee berry borer (CBB) in sun coffee farms in Southeastern Brazil. Considering the ecological interactions between ants and CBB at three different stages of pest...

Security for Software-Defined Wireless Sensor Networks: Performance evaluation comparison

Gustavo Segura
Software-defined networking (SDN) is a paradigm that has been proposed as a holistic solution for the inherent problems of wireless sensor networks (WSN). Security is a challenge in WSN. Because of resources constraints, to implement very secure systems may be complicated. This project aims to study the SDN characteristics to establish real benefits of using SDN in WSN to improve its security. We will carry out a performace evaluation and comparison between traditionals WSN and...

Data from: Organisation enhances collective vigilance in the hovering guards of Tetragonisca angustula bees

Kyle Shackleton, Denise A. Alves, Francis L.W. Ratnieks & Francis L W Ratnieks
One benefit of group living is vigilance against predators. Previous studies have investigated the group size effect, where individual vigilance decreases as group size increases without reducing the overall ability of the group to detect predators. However, there has been comparatively little research on whether the positioning of individuals can improve the collective vigilance of the group. We studied the coordination of vigilance and its effect on predator detection in the eusocial bee Tetragonisca angustula....

Data from: Males, but not females, perform strategic mate searching movements between host plants in a leaf beetle with scramble competition polygyny

Danilo G. Muniz, Martha L. Baena, Rogélio Macías-Ordóñez & Glauco Machado
1. Mate searching is assumed to be performed mostly by males, but when females benefit from multiple mating or are under risk of failing to mate, they may also perform mate searching. This is especially important in scramble competition polygynies, in which mate searching is the main mechanism of mate competition. Typically, more mobile individuals are expected to achieve higher mating success because mobility increases their probability of finding mates. 2. If we assume individual...

Data from: Evidence for heterochrony in the cranial evolution of fossil crocodyliforms

Pedro L. Godoy, Gabriel S. Ferreira, Felipe C. Montefeltro, Bruno C. Vila Nova, Richard J. Butler & Max C. Langer
The southern supercontinent of Gondwana was home to an extraordinary diversity of stem-crocodylians (Crocodyliformes) during the Late Cretaceous. The remarkable morphological disparity of notosuchian crocodyliforms indicates that this group filled a wide range of ecological roles more frequently occupied by other vertebrates. Among notosuchians, the distinctive cranial morphology and large body sizes of Baurusuchidae suggest a role as apex predators in ecosystems in which the otherwise dominant predatory theropod dinosaurs were scarce. Large-bodied crocodyliforms, modern...

Data from: Recent chapters of Neotropical history overlooked in phylogeography: shallow divergence explains phenotype and genotype uncoupling in Antilophia manakins

Fábio Raposo Do Amaral, Marcos M. Coelho, Alexandre Aleixo, Leilton W. Luna, Péricles S. Do Rêgo, Thainara O. Souza, Weber A.G. Silva & Gregory Thom
Establishing links between phenotypic and genotypic variation is a central goal of evolutionary biology, as they might provide important insights into evolutionary processes shaping genetic and species diversity in nature. One of the more intriguing possibilities is when no genetic divergence is found to be associated with conspicuous phenotypic divergence. In that case, speciation theory predicts that phenotypic divergence may still occur in the presence of significant gene flow—thereby resulting in little genomic divergence—when genetic...

Data from: Jaguar Movement Database: a GPS-based movement dataset of an apex predator in the Neotropics

Ronaldo G. Morato, Jeffrey J. Thompson, Agustín Paviolo, J. Antonio De La Torre, Fernando Lima, , Rogério C. Paula, , Leandro Silveira, Daniel L.Z. Kantek, Emiliano E. Ramalho, Louise Maranhão, Mario Haberfeld, Denis A. Sana, Rodrigo A. Medellin, Eduardo Carrillo, Victor Montalvo, Octavio Monroy-Vilchis, Paula Cruz, Anah Tereza Jácomo, Natalia M. Torres, Giselle B. Alves, Ivonne Cassaigne, Ron Thompson, Carolina Saenz-Bolanos … & Joares A. May
The field of movement ecology has rapidly grown during the last decade, with important advancements in tracking devices and analytical tools that have provided unprecedented insights into where, when, and why species move across a landscape. Although there has been an increasing emphasis on making animal movement data publicly available, there has also been a conspicuous dearth in the availability of such data on large carnivores. Globally, large predators are of conservation concern. However, due...

Data from: Evolution of morphological integration in the skull of Carnivora (Mammalia): changes in Canidae lead to increased evolutionary potential of facial traits

Fabio Andrade Machado, Thiago Macek Gonçalves Zahn & Gabriel Marroig
Morphological integration refers to the fact that different phenotypic traits of organisms are not fully independent from each other, and tend to covary to different degrees. The covariation among traits is thought to reflect properties of the species' genetic architecture and thus can have an impact on evolutionary responses. Furthermore, if morphological integration changes along the history of a group, inferences of past selection regimes might be problematic. Here we evaluated the stability and evolution...

Data from: An affordable apparatus for fine‐controlled emulation of buzzing frequencies of bees for the testing hypothesis in buzz interactions

Ernani V. Rodrigues, Júlia R. Riguete, Henrique R.C. Pereira, Juliétty A. Tesch & Ary G. Silva
1. The buzzing foraging behavior of female bees for pollen harvesting called the attention of early pollination biologists. Flower-types that demand this buzzing behavior comprise about 20.000 species of different and phylogenetically unrelated plant taxa, suggesting that it had independently evolved many times among the flowering plants. Between the late 70’s and early 80’s, theoretical papers had modeled the energetics of buzz-pollination, but, up to this moment, no hypothesis was experimentally tested concerning the theoretical...

Data from: Origin and hidden diversity within the poorly known Galápagos snake radiation (Serpentes: Dipsadidae)

Hussam Zaher, Mario H. Yánez-Munõz, Miguel T. Rodrigues, Roberta Graboski, Fabio A. Machado, Marco Altamirano-Benavides, Sandro L. Bonatto & Felipe G. Grazziotin
Galápagos snakes are among the least studied terrestrial vertebrates of the Archipelago. Here, we provide a phylogenetic analysis and a time calibrated tree for the group, based on a sampling of the major populations known to occur in the Archipelago. Our study revealed the presence of two previously unknown species from Santiago and Rábida Islands, and one from Tortuga, Isabela, and Fernandina. We also recognize six additional species of Pseudalsophis in the Galápagos Archipelago (Pseudalsophis...

Data from: Local adaptation in mainland anole lizards: Integrating population history and genome-environment associations

Ivan Prates, Anna Penna, Miguel Trefaut Rodrigues & Ana Carolina Carnaval
Environmental gradients constrain physiological performance and thus species’ ranges, suggesting that species occurrence in diverse environments may be associated with local adaptation. Genome-environment association analyses (GEAA) have become central for studies of local adaptation, yet they are sensitive to the spatial orientation of historical range expansions relative to landscape gradients. To test whether potentially adaptive genotypes occur in varied climates in wide-ranged species, we implemented GEAA on the basis of genome-wide data from the anole...

Data from: Functional redundancy in bird community decreases with riparian forest width reduction

Lucas A. Maure, Rodolpho C. Rodrigues, Ângelo V. Alcântara, Bruno F.C.B. Adorno, Douglas L. Santos, Eduardo L. Abreu, Rafael M. Tanaka, Rute M. Gonçalves, Erica Hasui & Bruno F. C. B. Adorno
1. Riparian ecosystems are suffering anthropogenic threats that reduce biodiversity and undermine ecosystem services. However, there is a great deal of uncertainty about the way species composition of assemblages is related to ecosystem function, especially in a landscape fragmentation context. 2. Here we assess the impact of habitat loss and disturbance on Functional Diversity (FD) components Functional Redundancy (FRed), Functional Evenness (FEve) and Functional Richness (FRic) of riparian forest bird assemblages to evaluate (1) how...
