Data from: Lessons from genome skimming of arthropod-preserving ethanol

Benjamin Linard, Paula Arribas, Carmelo Andújar, Alex Crampton-Platt & Alfried P. Vogler
Field-collected specimens of invertebrates are regularly killed and preserved in ethanol, prior to DNA extraction from the specimens, while the ethanol fraction is usually discarded. However, DNA may be released from the specimens into the ethanol, which can potentially be exploited to study species diversity in the sample without the need for DNA extraction from tissue. We used shallow shotgun sequencing of the total DNA to characterize the preservative ethanol from two pools of insects...

Data from: Is predictability salient? A study of attentional capture by auditory patterns

Rosy Southwell, Anna Baumann, Cécile Gal, Nicolas Barascud, Karl Friston & Maria Chait
In this series of behavioural and electroencephalography (EEG) experiments, we investigate the extent to which repeating patterns of sounds capture attention. Work in the visual domain has revealed attentional capture by statistically predictable stimuli, consistent with predictive coding accounts which suggest that attention is drawn to sensory regularities. Here, stimuli comprised rapid sequences of tone pips, arranged in regular (REG) or random (RAND) patterns. EEG data demonstrate that the brain rapidly recognizes predictable patterns manifested...

Data from: Time-calibrated molecular phylogeny of pteropods

Alice K. Burridge, Christine Hörnlein, Arie W. Janssen, Martin Hughes, Stephanie L. Bush, Ferdinand Marlétaz, Rebeca Gasca, Annelies C. Pierrot-Bults, Ellinor Michel, Jonathan A. Todd, Jeremy R. Young, Karen J. Osborn, Steph B.J. Menken, Katja T.C.A. Peijnenburg, Katja T. C. A. Peijnenburg & Steph B. J. Menken
Pteropods are a widespread group of holoplanktonic gastropod molluscs and are uniquely suitable for study of long-term evolutionary processes in the open ocean because they are the only living metazoan plankton with a good fossil record. Pteropods have been proposed as bioindicators to monitor the impacts of ocean acidification and in consequence have attracted considerable research interest, however, a robust evolutionary framework for the group is still lacking. Here we reconstruct their phylogenetic relationships and...

Data from: Dynamic population codes of multiplexed stimulus features in primate area MT

Erin Goddard, Samuel G. Solomon & Thomas A. Carlson
The middle-temporal area (MT) of primate visual cortex is critical in the analysis of visual motion. Single-unit studies suggest that the response dynamics of neurons within area MT depend on stimulus features, but how these dynamics emerge at the population level, and how feature representations interact, is not clear. Here, we used multivariate classification analysis to study how stimulus features are represented in the spiking activity of populations of neurons in area MT of marmoset...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...

Data from: Variation in promiscuity and sexual selection drives avian rate of Faster-Z evolution

Alison E. Wright, Peter W. Harrison, Fabian Zimmer, Stephen H. Montgomery, Marie A. Pointer & Judith E. Mank
Higher rates of coding sequence evolution have been observed on the Z chromosome relative to the autosomes across a wide range of species. However, despite a considerable body of theory, we lack empirical evidence explaining variation in the strength of the Faster-Z Effect. To assess the magnitude and drivers of Faster-Z Evolution, we assembled six de novo transcriptomes, spanning 90 million years of avian evolution. Our analysis combines expression, sequence and polymorphism data with measures...

Data from: Blinded by the load: attention, awareness and the role of perceptual load

Nilli Lavie, Diane M. Beck & Nikos Konstantinou
What is the relationship between attention and conscious awareness? Awareness sometimes appears to be restricted to the contents of focused attention, yet at other times irrelevant distractors will dominate awareness. This contradictory relationship has also been reflected in an abundance of discrepant research findings leading to an enduring controversy in cognitive psychology. Lavie's load theory of attention suggests that the puzzle can be solved by considering the role of perceptual load. Although distractors will intrude...

Data from: Coupling of palaeontological and neontological reef coral data improves forecasts of biodiversity responses under global climatic change

Lewis A. Jones, Philip D. Mannion, Alexander Farnsworth, Paul J. Valdes, Sarah-Jane Kelland & Peter A. Allison
Reef corals are currently undergoing climatically-driven poleward range expansions, with some evidence for equatorial range retractions. Predicting their response to future climate scenarios is critical to their conservation, but ecological models are based only on short-term observations. The fossil record provides the only empirical evidence for the long-term response of organisms under perturbed climate states. The palaeontological record from the Last Interglacial (LIG; 125,000 years ago), a time of global warming, suggests that reef corals...

Data from: Cross-species hybridization and the origin of North African date palms

Jonathan M. Flowers, Khaled M. Hazzouri, Muriel Gros-Balthazard, Ziyi Mo, Konstantina Koutroumpa, Andreas Perrakis, Sylvie Ferrand, Hussam S. M. Khierallah, Dorian Q. Fuller, Frederique Aberlenc, Christini Fournaraki & Michael D. Purugganan
Date palm (Phoenix dactylifera L.) is a major fruit crop of arid regions that were domesticated 7,000 y ago in the Near or Middle East. This species is cultivated widely in the Middle East and North Africa, and previous population genetic studies have shown genetic differentiation between these regions. We investigated the evolutionary history of P. dactylifera and its wild relatives by resequencing the genomes of date palm varieties and five of its closest relatives....

Data from: Selective bird predation on the peppered moth: the last experiment of Michael Majerus

Laurence M. Cook, Bruce S. Grant, Ilik J. Saccheri & James Mallet
Colour variation in the peppered moth Biston betularia was long accepted to be under strong natural selection. Melanics were believed to be fitter than pale morphs because of lower predation at daytime resting sites on dark, sooty bark. Melanics became common during the industrial revolution, but since 1970 there has been a rapid reversal, assumed to have been caused by predators selecting against melanics resting on today's less sooty bark. Recently, these classical explanations of...

Data from: Visual and non-visual navigation in blind patients with a retinal prosthesis

Sara Garcia, Karin Petrini, Gary S. Rubin, Lyndon Da Cruz & Marko Nardini
Human adults with normal vision can combine visual landmark and non-visual self-motion cues to improve their navigational precision. Here we asked whether blind individuals treated with a retinal prosthesis could also benefit from using the resultant new visual signal together with non-visual information when navigating. Four patients (blind for 15-52 years) implanted with the Argus II retinal prosthesis (Second Sight Medical Products Inc. Sylmar, CA), and five age-matched and six younger controls, participated. Participants completed...

Data from:Spatio-temporal networks: reachability, centrality and robustness

Matthew J. Williams & Mirco Musolesi
Recent advances in spatial and temporal networks have enabled researchers to more-accurately describe many real-world systems such as urban transport networks. In this paper, we study the response of real-world spatio-temporal networks to random error and systematic attack, taking a unified view of their spatial and temporal performance. We propose a model of spatio-temporal paths in time-varying spatially embedded networks which captures the property that, as in many real-world systems, interaction between nodes is non-instantaneous...

Data from: Identification of the Beagle 2 lander on Mars

John C. Bridges, Jim Clemmet, Michael Croon, Mark R. Sims, Derek Pullan, Jan-Peter Muller, Yu Tao, Xiong Xiong, Alfiah R. Putri, Tim Parker, Stuart M. R. Turner & Judith M. Pillinger
The 2003 Beagle 2 Mars lander has been identified in Isidis Planitia at 90.43° E, 11.53° N, close to the predicted target of 90.50° E, 11.53° N. Beagle 2 was an exobiology lander designed to look for isotopic and compositional signs of life on Mars, as part of the European Space Agency Mars Express (MEX) mission. The 2004 recalculation of the original landing ellipse from a 3-sigma major axis from 174 km to 57 km,...

Full-likelihood genomic analysis clarifies a complex history of species divergence and introgression: the example of the erato-sara group of Heliconius butterflies

Yuttapong Thawornwattana, Fernando Seixas, Ziheng Yang & James Mallet
Introgression plays a key role in adaptive evolution and species diversification in many groups of species. However, frequent hybridization and gene flow between species makes estimation of the species phylogeny and key population parameters challenging. Here, we show that by accounting for phasing and by using full-likelihood analysis methods, introgression histories and population parameters can be estimated reliably from whole-genome sequence data. We employ full-likelihood methods under the multispecies coalescent (MSC) model with and without...

Analysis of independent cohorts of outbred CFW mice reveals novel loci for behavioral and physiological traits and identifies factors determining reproducibility

Jennifer Zou, Shyam Gopalakrishnan, Clarissa Parker, Jerome Nicod, Richard Mott, Na Cai, Arimantas Lionikas, Robert Davies, Abraham Palmer & Jonathan Flint
Combining samples for genetic association is standard practice in human genetic analysis of complex traits, but is rarely undertaken in rodent genetics. Here, using 23 phenotypes and genotypes from two independent laboratories, we obtained a sample size of 3,076 commercially available outbred mice and identified 70 loci, more than double the number of loci identified in the component studies. Fine-mapping in the combined sample reduced the number of likely causal variants, with a median reduction...

Bushmeat yields, species extinction rates and ecosystem-level impacts of bushmeat harvesting as predicted by the Madingley General Ecosystem Model

Tatsiana Barychka, Georgina Mace & Drew Purves
The datasets contain data generated using the Madingley General Ecosystem Model for experiments decribed in the paper: "T. Barychka, G.M.Mace and D.W.Purves (2021) The Madingley General Ecosystem Model predicts bushmeat yields, species extinction rates and ecosystem-level impacts of bushmeat harvesting. Oikos." The Madingley General Ecosystem Model was used to generate predictions of bushmeat yields, extinction rates and broader ecosystem impacts for a range of harvesting intensities of duiker-sized endothermic herbivores. Duiker antelope (such as Cephalophus...

Data from: A circuit mechanism for decision making biases and NMDA receptor hypofunction

Sean Cavanagh, Norman Lam, John Murray, Laurence Hunt & Steven Kennerley
Decision-making biases can be features of normal behaviour, or deficits underlying neuropsychiatric symptoms. We used behavioural psychophysics, spiking-circuit modelling and pharmacological manipulations to explore decision-making biases during evidence integration. Monkeys showed a pro-variance bias (PVB): a preference to choose options with more variable evidence. The PVB was also present in a spiking circuit model, revealing a potential neural mechanism for this behaviour. To model possible effects of NMDA receptor (NMDA-R) antagonism on this behaviour, we...

Tuning cell behavior with nanoparticle shape

Loris Rizzello, Alessandro Poma, Eva Liatsi-Douvitsa, Giuseppe Battaglia, Valeria De Matteis, Cesare De Pace, Adrian Joseph, Claudia Contini, Edoardo Scarpa, Josep Martí, Loris Rizzello & Senio De Souza
We investigated how the shape of polymeric vesicles, made by the exact same material, impacts the replication activity and metabolic state of both cancer and non-cancer cell types. First, we isolated discrete geometrical structures (spheres and tubes) from a heterogeneous sample using density-gradient centrifugation. Then, we characterized the cellular internalization and the kinetics of uptake of both types of polymersomes in different cell types (either cancer or non-cancer cells). We also investigated the cellular metabolic...

Data from: Palaeontology meets metacommunity ecology: The Maastricthian dinosaur fossil record of North America as a case study

Jorge García-Girón, Jani Heino, Janne Alahuhta, Alfio Alessandro Chiarenza & Steve Brusatte
Documenting the patterns and potential associated processes of ancient biotas has always been a central challenge in palaeontology. Over the last decades, intense debate has focused on the organisation of dinosaur–dominated communities, yet no general consensus has been reached on how these communities were organised in a spatial context and if primarily affected by abiotic or biotic agents. Here, we used analytical routines typically applied in metacommunity ecology to provide novel insights into dinosaurian distributions...

Data from: Anthropogenic extinctions conceal widespread evolution of flightlessness in birds

Ferran Sayol, Manuel J. Steinbauer, Tim M. Blackburn, Alexandre Antonelli & Søren Faurby
Human-driven extinctions can affect our understanding of evolution, through the nonrandom loss of certain types of species. Here, we explore how knowledge of a major evolutionary transition—the evolution of flightlessness in birds—is biased by anthropogenic extinctions. Adding data on 581 known anthropogenic extinctions to the extant avifauna increases the number of species by 5%, but quadruples the number of flightless species. The evolution of flightlessness in birds is a widespread phenomenon, occurring in more than...

Evolution and development at the origin of a phylum

Bradley Deline, Jeffery Thompson, Nicholas Smith, Samuel Zamora, Imran Rahman, Sarah Sheffield, William Ausich, Thomas Kammer & Colin Sumrall
Quantifying morphological evolution is key to determining the patterns and processes underlying the origin of phyla. We constructed a hierarchical morphological character matrix to characterize the radiation and establishment of echinoderm body plans during the early Paleozoic. This showed that subphylum-level clades diverged gradually through the Cambrian, and the distinctiveness of the resulting body plans was amplified by the extinction of transitional forms and obscured by convergent evolution during the Ordovician. Higher-order characters that define...

Data from: An integrative phylogenomic approach to elucidate the evolutionary history and divergence times of Neuropterida (Insecta: Holometabola)

Alexandros Vasilikopoulos, Bernhard Misof, Karen Meusemann, Doria Lieberz, Tomáš Flouri, Rolf G. Beutel, Oliver Niehuis, Torsten Wappler, Jes Rust, Ralph S. Peters, Alexander Donath, Lars Podsiadlowski, Christoph Mayer, Daniela Bartel, Alexander Böhm, Shanlin Liu, Paschalia Kapli, Carola Greve, James E. Jepson, Xingyue Liu, Xin Zhou, Horst Aspöck & Ulrike Aspöck
Background The latest advancements in DNA sequencing technologies have facilitated the resolution of the phylogeny of insects, yet parts of the tree of Holometabola remain unresolved. The phylogeny of Neuropterida has been extensively studied, but no strong consensus exists concerning the phylogenetic relationships within the order Neuroptera, and the timeline of diversification of thelineages of Neuropterida. Here, we assembled a novel transcriptomic dataset to address previously unresolved issues in the phylogeny of Neuropterida and to...

Data from: Contrasting trajectories of morphological diversification on continents and islands in the Afrotropical white-eye radiation

Julia J. Day, Frederico C. Martins, Joseph A. Tobias & David J. Murrell
Aim Morphological and lineage evolution are predicted to follow different patterns in island and mainland radiations. However, the extent to which these geographical contexts influence evolutionary trajectories remains poorly understood, in part because few studies have focused on species-rich clades colonising continents and archipelagos over comparable timeframes. Focusing on a diverse songbird clade radiating on the African continent and adjacent islands, we tested whether morphological evolution is best explained by adaptive or non-adaptive processes, and...

Data from: Current ecology, not ancestral dispersal patterns, influences menopause symptom severity

Yuping Yang, Megan Arnot & Ruth Mace
All human females who reach midlife experience menopause, however, it is currently unclear why women experience this period of infertility, and why it is accompanied by many unpleasant symptoms. Using primary data from four ethnic groups in China, we test an existing theory that age of menopause and its symptoms are the result of intragenomic conflict between maternally and paternally inherited genes, with the outcome of such conflict predicted to be contingent on the ancestral...

Data from: Near-infrared dual bioluminescence imaging in mouse models of cancer using infraluciferin

James Anderson & Martin Pule
Bioluminescence imaging (BLI) is ubiquitous in scientific research for the sensitive tracking of biological processes in small animal models. However, due to the attenuation of visible light by tissue, and the limited set of near-infrared bioluminescent enzymes, BLI is largely restricted to monitoring single processes in vivo. Here we show, that by combining stabilised colour mutants of firefly luciferase (FLuc) with the luciferin (LH2) analogue infraluciferin (iLH2), near-infrared dual BLI can be achievedin vivo. The...
