Data from: The reproductive biology of two poorly known relatives of the fig (Ficus) and insights into the evolution of the fig syconium.

Chris Thorogood, Naomi Dalton, Aisa Irvine & Simon Hiscock
We conducted the first detailed investigation of the floral architecture and reproductive biology of two species from the genus Dorstenia, which are poorly known relatives of Ficus (Moraceae). Our aims were to extend and refine knowledge of the understudied genus Dorstenia and to explore possible insights into the evolution of the fig syconium. We characterised four key stages of floral development using light microscopy, scanning electron microscopy and histological staining. Reproductive biology was found to...

Data from: Whole-body photoreceptor networks are independent of ‘lenses’ in brittle stars

Lauren Sumner-Rooney, Imran A. Rahman, Julia D. Sigwart & Esther Ullrich-Lüter
Photoreception and vision are fundamental aspects of animal sensory biology and ecology, but important gaps remain in our understanding of these processes in many species. The colour-changing brittle star Ophiocoma wendtii is iconic in vision research, speculatively possessing a unique whole-body visual system that incorporates information from nerve bundles underlying thousands of crystalline ‘microlenses’. The hypothesis that these form a sophisticated compound eye-like system regulated by chromatophore movement has been extensively reiterated, with consequent investigations...

Data from: An adaptable but threatened big cat: density, diet and prey selection of the Indochinese leopard (Panthera pardus delacouri) in eastern Cambodia

Susana Rostro-García, Jan F. Kamler, Rachel Crouthers, Keo Sopheak, Sovanna Prum, Visattha In, Chanratana Pin, Anthony Caragiulo & David W. Macdonald
We studied the Indochinese leopard (Panthera pardus delacouri) in eastern Cambodia, in one of the few potentially remaining viable populations in Southeast Asia. The aims were to determine the: (i) current leopard density in Srepok Wildlife Sanctuary (SWS) and (ii) diet, prey selection and predation impact of leopard in SWS. The density, estimated using spatially explicit capture–recapture models, was 1.0 leopard/100 km2, 72% lower than an estimate from 2009 at the same site, and one...

Data from: Spatiotemporal incidence of Zika and associated environmental drivers for the 2015-2016 epidemic in Colombia

Amir S. Siraj, I. Rodriguez-Barraquer, Christopher M. Barker, Natalia Tejedor-Garavito, Dennis Harding, Christopher Lorton, Dejan Lukacevic, Gene Oates, Guido Espana, Moritz U. G. Kraemer, Carrie Manore, Michael A. Johansson, Andrew J. Tatem, Robert C. Reiner & T. Alex Perkins
Despite a long history of mosquito-borne virus epidemics in the Americas, the impact of the Zika virus (ZIKV) epidemic of 2015-2016 was unexpected. The need for scientifically informed decision-making is driving research to understand the emergence and spread of ZIKV. To support that research, we assembled a data set of key covariates for modeling ZIKV transmission dynamics in Colombia, where ZIKV transmission was widespread and the government made incidence data publically available. On a weekly...

Data from: Structural and defensive roles of angiosperm leaf venation network reticulation across an Andes-Amazon elevation gradient

Benjamin Blonder, Norma Salinas, Lisa Patrick Bentley, Alexander Shenkin, Percy Orlando Chambi Porroa, Yolvi Valdez Tejeira, Tatiana Erika Boza Espinoza, Gregory R. Goldsmith, Lucas Enrico, Roberta Martin, Gregory P. Asner, Sandra Díaz, Brian J. Enquist, Yadvinder Malhi & Lisa Patrick Bentley
1.The network of minor veins of angiosperm leaves may include loops (reticulation). Variation in network architecture has been hypothesized to have hydraulic and also structural and defensive functions. 2.We measured venation network trait space in eight dimensions for 136 biomass-dominant angiosperm tree species along a 3,300 m elevation gradient in southeastern Peru. We then examined the relative importance of multiple ecological, and evolutionary predictors of reticulation. 3.Variation in minor venation network reticulation was constrained to...

Data from: Lepidosaurian diversity in the Mesozoic–Paleogene: the potential roles of sampling biases and environmental drivers

Terri J. Cleary, Roger B.J. Benson, Susan E. Evans, Paul M. Barrett & Roger B. J. Benson
Lepidosauria is a speciose clade with a long evolutionary history, but there have been few attempts to explore its taxon-richness through time. Here we estimate patterns of terrestrial lepidosaur genus diversity for the Triassic–Paleogene (252–23 Ma), and compare observed and sampling-corrected richness curves generated using Shareholder Quorum Subsampling and classical rarefaction. Generalized least-squares regression (GLS) is used to investigate the relationships between richness, sampling and environmental proxies. We found low levels of richness from the...

Data from: The evolutionary history of polycotylid plesiosaurians

Valentin Fischer, Roger B J Benson, Patrick S Druckenmiller, Hilary F Ketchum, Nathalie Bardet, P. S. Druckenmiller, R. B. J. Benson, V. Fischer & H. F. Ketchum
Polycotylidae is a clade of plesiosaurians that appeared during the Early Cretaceous and became speciose and abundant early in the Late Cretaceous. However, this radiation is poorly understood. Thililua longicollis from the Middle Turonian of Morocco is an enigmatic taxon possessing an atypically long-neck and, as originally reported, a series of unusual cranial features that cause unstable phylogenetic relationships for polycotylids. We reinterpret the holotype specimen of Thililua longicollis and clarify its cranial anatomy. Thililua...

Data from: The evolutionary history of dogs in the Americas

Máire Ní Leathlobhair, Angela R. Perri, Evan K. Irving-Pease, Kelsey E. Witt, Anna Linderholm, James Haile, Ophelie Lebrasseur, Carly Ameen, Jeffrey Blick, Adam R. Boyko, Selina Brace, Yahaira Nunes Cortes, Susan J. Crockford, Alison Devault, Evangelos A. Dimopoulos, Morley Eldridge, Jacob Enk, Shyam Gopalakrishnan, Kevin Gori, Vaughan Grimes, Eric Guiry, Anders J. Hansen, Ardern Hulme-Beaman, John Johnson, Andrew Kitchen … & Laurent A. F. Frantz
Dogs were present in the Americas prior to the arrival of European colonists, but the origin and fate of these pre-contact dogs are largely unknown. We sequenced 71 mitochondrial and seven nuclear genomes from ancient North American and Siberian dogs spanning ~9,000 years. Our analysis indicates that American dogs were not domesticated from North American wolves. Instead, American dogs form a monophyletic lineage that likely originated in Siberia and dispersed into the Americas alongside people....

Data from: Inter-annual dynamics and persistence of small mammal communities in a selectively logged tropical forest in Borneo

Philip M. Chapman, Oliver R. Wearn, Terhi Riutta, Chris Carbone, J. Marcus Rowcliffe, Henry Bernard, Robert M Ewers & Robert. M. Ewers
Understanding temporal change and long-term persistence of species and communities is vital if we are to accurately assess the relative values of human-modified habitats for biodiversity. Despite a large literature and emerging consensus demonstrating a high conservation value of selectively logged tropical rainforests, few studies have taken a long-term perspective. We resampled small mammals (≤1kg) in a heavily logged landscape in Sabah, Borneo between 2011 and 2016 to investigate temporal patterns of species-level changes in...

Data from: Behavioural thermoregulation via microhabitat selection of winter sleeping areas in an endangered primate: Implications for habitat conservation

Liz A.D. Campbell, Patrick J. Tkaczynski, Mohamed Mouna, Abderrahim Derrou, Lahcen Oukannou, Bonaventura Majolo, Els Van Lavieren & Liz A. D. Campbell
Strategic microhabitat selection allows animals in seasonally cold environments to reduce homeostatic energy costs, particularly overnight when thermoregulatory demands are greatest. Suitable sleeping areas may therefore represent important resources for winter survival. Knowledge of microhabitat use and potential impacts of anthropogenic habitat modification can aid species conservation through development of targeted habitat management plans. Wild, endangered Barbary macaques (Macaca sylvanus) in logged cedar-oak forest were studied to investigate 1) the hypothesis that macaques select winter...

A time-series of strains in response to wind measured on 19 trees in Danum Valley, Malaysia

T. Jackson
Strain data measured on the trunks of 19 trees in the Danum Valley, Malaysia. It also contains wind speed data measured using anemometers attached to emergent trees nearby. This data can be used to extract the fundamental swaying frequencies of these trees, and to quantify the relationship between wind speed and bending strain and so estimate wind damage risk. This data would be useful for anyone studying the interaction between wind and trees. The tallest...

Data from: Privatisation rescues essential function following loss of cooperation

Sandra Breum Andersen, Melanie Ghoul, Rasmus Lykke Marvig, Zhuo-Bin Lee, Søren Molin, Helle Krogh Johansen, Ashleigh S. Griffin, Rasmus L Marvig & Ashleigh S Griffin
A single cheating mutant can lead to the invasion and eventual eradication of cooperation from a population. Consequently, cheat invasion is often considered equal to extinction in empirical and theoretical studies of cooperator-cheat dynamics. But does cheat invasion necessarily equate extinction in nature? By following the social dynamics of iron metabolism in Pseudomonas aeruginosa during cystic fibrosis lung infection, we observed that individuals evolved to replace cooperation with a ‘private’ behaviour. Phenotypic assays showed that...

Data from: Estimating environmental suitability

John M. Drake & Robert L. Richards
Methods for modeling species’ distributions in nature are typically evaluated empirically with respect to data from observations of species occurrence and, occasionally, absence at surveyed locations. Such models are relatively “theory‐free.” In contrast, theories for explaining species’ distributions draw on concepts like fitness, niche, and environmental suitability. This paper proposes that environmental suitability be defined as the conditional probability of occurrence of a species given the state of the environment at a location. Any quantity...

Data from: Parallel pattern of differentiation at a genomic island shared between clinal and mosaic hybrid zones in a complex of cryptic seahorse lineages

Florentine Riquet, Cathy Liautard-Haag, Lucy Woodall, Carmen Bouza, Patrick Louisy, Bojan Hamer, Francisco Otero-Ferrer, Philippe Aublanc, Vickie Béduneau, Olivier Briard, Tahani El Ayari, Sandra Hochscheid, Khalid Belkhir, Sophie Arnaud-Haond, Pierre-Alexandre Gagnaire & Nicolas Bierne
Diverging semi-isolated lineages either meet in narrow clinal hybrid zones, or have a mosaic distribution associated with environmental variation. Intrinsic reproductive isolation is often emphasized in the former and local adaptation in the latter, although both can contribute to isolation. Rarely these two patterns of spatial distribution are reported in the same study system. Here we report that the long-snouted seahorse Hippocampus guttulatus is subdivided into discrete panmictic entities by both types of hybrid zones....

Data from: Understanding co-occurrence by modelling species simultaneously with a Joint Species Distribution Model (JSDM)

Laura J. Pollock, Reid Tingley, William K. Morris, Nick Golding, Robert B. O'Hara, Kirsten M. Parris, Peter A. Vesk & Michael A. McCarthy
A primary goal of ecology is to understand the fundamental processes underlying the geographic distributions of species. Two major strands of ecology – habitat modelling and community ecology – approach this problem differently. Habitat modellers often use species distribution models (SDMs) to quantify the relationship between species’ and their environments without considering potential biotic interactions. Community ecologists, on the other hand, tend to focus on biotic interactions and, in observational studies, use co‐occurrence patterns to...

Data from: Hosts do not simply outsource pathogen resistance to protective symbionts

Jan Hrcek, Benjamin J. Parker, Ailsa H.C. McLean, Jean-Christophe Simon, Ciara M. Mann & H. Charles J. Godfray
Microbial symbionts commonly protect their hosts from natural enemies, but it is unclear how protective symbionts influence the evolution of host immunity to pathogens. One possibility is that ‘extrinsic’ protection provided by symbionts allows hosts to reduce investment in ‘intrinsic’ immunological resistance mechanisms. We tested this idea using pea aphids (Acyrthosiphon pisum) and their facultative bacterial symbionts that increase host resistance to the fungal pathogen Pandora neoaphidis. The pea aphid taxon is composed of multiple...

Data from: Glutamate receptor delta2 serum antibodies in paediatric opsoclonus myoclonus ataxia syndrome

Georgina Berridge, David A Menassa, Teresa Moloney, Patrick J Waters, Imogen Welding, Selina Thomsen, Sameer Zuberi, Roman Fischer, A. Radu Aricescu, Michael Pike, Russell C Dale, Benedikt Kessler, Angela Vincent, Ming Lim, Sarosh R Irani & Bethan Lang
Objective: To identify neuronal surface antibodies in opsoclonus myoclonus ataxia syndrome (OMAS) usingcontemporary antigen discovery methodology. Methods: OMAS patient serum IgG immunohistochemistry using age-equivalent rat cerebellar tissue was followed by immunoprecipitation, gel electrophoresis and mass spectrometry. Data are available via ProteomeXchange (identifier PXD009578). This generated a list of potential neuronal surface cerebellar autoantigens. Live cell-based assays (CBA) were used to confirm membrane-surface antigens and adsorb antigen-specific IgGs. The serological results were compared to the clinical...

Data from: Experimental signal dissection and method sensitivity analyses reaffirm the potential of fossils and morphology in the resolution of the relationship of angiosperms and Gnetales

Mario Coiro, Guillaume Chomicki & James A. Doyle
The placement of angiosperms and Gnetales in seed plant phylogeny remains one of the most enigmatic problems in plant evolution, with morphological analyses (which have usually included fossils) and molecular analyses pointing to very distinct topologies. Almost all morphology-based phylogenies group angiosperms with Gnetales and certain extinct seed plant lineages, while most molecular phylogenies link Gnetales with conifers. In this study, we investigate the phylogenetic signal present in published seed plant morphological datasets. We use...

Data from: Rewilding in the English Uplands: policy and practice

Christopher J. Sandom, Benedict Dempsey, David Bullock, Adrian Ely, Paul Jepson, Stefan Jimenez-Wisler, Adrian Newton, Nathalie Pettorelli & Rebecca A. Senior
Rewilding is gaining momentum as a new approach to restore and conserve biodiversity and ecosystem services, despite being imprecisely defined, controversial, and with limited explicit empirical supporting evidence (Lorimer et al., 2015; Pettorelli et al., 2018; Svenning et al., 2016). In a case study region (the English uplands), we discuss what rewilding means to practitioners and policy makers; the risks, opportunities, and barriers to implementation, and potential paths for policy and practice.

Data from: Hotspot mutations and ColE1 plasmids contribute to the fitness of Salmonella Heidelberg in poultry litter

Adelumola Oladeinde, Kimberly Cook, Alex Orlek, Greg Zock, Kyler Herrington, Nelson Cox, Jodie Plumblee Lawrence & Carolina Hall
Salmonella enterica subsp. enterica serovar Heidelberg (S. Heidelberg) is a clinically-important serovar linked to food-borne illness, and commonly isolated from poultry. Investigations of a large, multistate outbreak in the USA in 2013 identified poultry litter (PL) as an important extra-intestinal environment that may have selected for specific S. Heidelberg strains. Poultry litter is a mixture of bedding materials and chicken excreta that contains chicken gastrointestinal (GI) bacteria, undigested feed, feathers, and other materials of chicken...

Data from: A neural mechanism underlying failure of optimal choice with multiple alternatives

Bolton K H Chau, Nils Kolling, Laurence T Hunt, Mark E Walton & Matthew F S Rushworth
Despite widespread interest in neural mechanisms of decision-making, most investigations focus on decisions between just two options. Here we adapt a biophysically plausible model of decision-making to predict how a key decision variable, the value difference signal—encoding how much better one choice is than another—changes with the value of a third, but unavailable, alternative. The model predicts a surprising failure of optimal decision-making: greater difficulty choosing between two options in the presence of a third...

Data from: The diversity of population responses to environmental change

Fernando Colchero, Owen R. Jones, Dalia A. Conde, Dave Hodgson, Felix Zajitschek, Benedikt R. Schmidt, Aurelio F. Malo, Susan C. Alberts, Peter H. Becker, Sandra Bouwhuis, Anne M. Bronikowski, Kristel M. De Vleeschouwer, Richard J. Delahay, Stefan Dummermuth, Eduardo Fernández-Duque, John Frisenvænge, Martin Hesselsøe, Sam Larson, Jean-Francois Lemaitre, Jennifer McDonald, David A.W. Miller, Colin O'Donnell, Craig Packer, Becky E. Raboy, Christopher J. Reading … & Chris J. Reading
The current extinction and climate change crises pressure us to predict population dynamics with ever-greater accuracy. Although predictions rest on the well-advanced theory of age-structured populations, two key issues remain poorly-explored. Specifically, how the age-dependency in demographic rates and the year-to-year interactions between survival and fecundity affect stochastic population growth rates. We use inference, simulations, and mathematical derivations to explore how environmental perturbations determine population growth rates for populations with different age-specific demographic rates and...

Data from: The influence of symbiotic bacteria on reproductive strategies and wing polyphenism in pea aphids responding to stress

Miguel L. Reyes, Alice M. Laughton, Benjamin James Parker, Hannah Wichmann, Maretta Fan, Daniel Sok, Jan Hrcek, Tarik Acevedo, Nicole M. Gerardo & Benjamin J. Parker
1. Environmental stressors can be key drivers of phenotypes, including reproductive strategies and morphological traits. The response to stress may be altered by the presence of microbial associates. For example, in aphids, facultative (secondary) bacterial symbionts can provide protection against natural enemies and stress induced by elevated temperatures. Furthermore, aphids exhibit phenotypic plasticity, producing winged (rather than wingless) progeny that may be better able to escape danger, and the combination of these factors improve the...

Environmental conditions at saiga calving and die-off sites in Kazakhstan, 1979 to 2016

S. Robinson
This dataset describes environmental conditions at 135 Saiga antelope calving sites (from a total of 214) in Kazakhstan where the predictor variables required for the modelling were available at sufficient resolution. Data collected included climatic variables associated with haemorrhagic septicaemia in the literature, including humidity, temperature and precipitation. Indicators of vegetation biomass, phenology and length of the winter preceding calving were represented using the Normalised Difference Vegetation Index (NDVI), snow depth and snow presence data....
