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),...

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...

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: 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...

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: Does biological intimacy shape ecological network structure? A test using a brood pollination mutualism on continental and oceanic islands

David H. Hembry, Rafael L. G. Raimundo, Erica A. Newman, Lesje Atkinson, Chang Guo, & Rosemary G. Gillespie
Biological intimacy—the degree of physical proximity or integration of partner taxa during their life cycles—is thought to promote the evolution of reciprocal specialization and modularity in the networks formed by co‐occurring mutualistic species, but this hypothesis has rarely been tested. Here, we test this “biological intimacy hypothesis” by comparing the network architecture of brood pollination mutualisms, in which specialized insects are simultaneously parasites (as larvae) and pollinators (as adults) of their host plants to that...

Data from: Age‐dependent leaf physiology and consequences for crown‐scale carbon uptake during the dry season in an Amazon evergreen forest

Loren P. Albert, Jin Wu, Neill Prohaska, Plinio Barbosa De Camargo, Travis E. Huxman, Edgard S. Tribuzy, Valeriy Y. Ivanov, Rafael S. Oliveira, Sabrina Garcia, Marielle N. Smith, Raimundo Cosme Oliveira Junior, Natalia Restrepo-Coupe, Rodrigo Da Silva, Scott C. Stark, Giordane A. Martins, Deliane V. Penha & Scott R. Saleska
* Satellite and tower-based metrics of forest-scale photosynthesis generally increase with dry season progression across central Amazônia, but the underlying mechanisms lack consensus. * We conducted demographic surveys of leaf age composition, and measured age-dependence of leaf physiology in broadleaf canopy trees of abundant species at a central eastern Amazon site. Using a novel leaf-to-branch scaling approach, we used this data to independently test the much-debated hypothesis—arising from satellite and tower-based observations—that leaf phenology could...

Data from: Contemporary ecological interactions improve models of past trait evolution

Matthew C. Hutchinson, Marilia P. Gaiarsa & Daniel B. Stouffer
Despite the fact that natural selection underlies both traits and interactions, evolutionary models often neglect that ecological interactions may, and in many cases do, influence the evolution of traits. Here, we explore the interdependence of ecological interactions and functional traits in the pollination associations of hawkmoths and flowering plants. Specifically, we develop an adaptation of the Ornstein-Uhlenbeck model of trait evolution that allows us to study the influence of plant corolla depth and observed hawkmoth-plant...

Data from: Hydrological niche segregation defines forest structure and drought tolerance strategies in a seasonal Amazon forest

Mauro Brum, Matthew A. Vadeboncoeur, Valeriy Ivanov, Heidi Asbjornsen, Scott Saleska, Luciana F. Alves, Deliane Penha, Jadson D. Dias, Luiz E.O.C. Aragão, Fernanda Barros, Paulo Bittencourt, Luciano Pereira & Rafael S. Oliveira
1) Understanding if and how trees coordinate rooting depth and aboveground hydraulic traits to define drought-resistance strategies in seasonal Amazon forests is a major gap to model parametrization aimed at predicting the effects of climate change in these ecosystems. 2) We assessed the rooting depth of 12 dominant tree species (representing ~ 42% of the forest basal area) in a seasonal Amazon forest, using the stable isotope ratios (δ18O and δ²H) of water collected from...

The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with...
