Data from: Symbiont strain is the main determinant of variation in Wolbachia-mediated protection against viruses across Drosophila species

Julien Martinez, Ignacio Tolosana, Suzan Ok, Sophie Smith, Kiana Snoeck, Jonathan P. Day, Frank Jiggins & Francis M. Jiggins
Wolbachia is a common heritable bacterial symbiont in insects. Its evolutionary success lies in the diverse phenotypic effects it has on its hosts coupled to its propensity to move between host species over evolutionary timescales. In a survey of natural host–symbiont associations in a range of Drosophila species, we found that 10 of 16 Wolbachia strains protected their hosts against viral infection. By moving Wolbachia strains between host species, we found that the symbiont genome...

Data from: Widespread paleopolyploidy, gene tree conflict, and recalcitrant relationships among the carnivorous Caryophyllales

Joseph F. Walker, Ya Yang, Moore J. Michael, Jessica Mikenas, Alfonso Timoneda, Samuel Frasier Brockington, Stephen Andrew Smith & Michael J. Moore
PREMISE OF STUDY: The carnivorous members of the large, hyperdiverse Caryophyllales (e.g., Venus flytrap, sundews, and Nepenthes pitcher plants) represent perhaps the oldest and most diverse lineage of carnivorous plants. However, despite numerous studies seeking to elucidate their evolutionary relationships, the early-diverging relationships remain unresolved. METHODS: To explore the utility of phylogenomic data sets for resolving relationships among the carnivorous Caryophyllales, we sequenced 10 transcriptomes, including all the carnivorous genera except those in the rare...

Data from: Exploring evolutionary relationships across the genome using topology weighting

Simon Henry Martin & Steven M. Van Belleghem
We introduce the concept of topology weighting, a method for quantifying relationships between taxa that are not necessarily monophyletic, and visualising how these relationships change across the genome. A given set of taxa can be related in a limited number of ways, but if each taxon is represented by multiple sequences, the number of possible topologies becomes very large. Topology weighting reduces this complexity by quantifying the contribution of each 'taxon topology' to the full...

Data from: Seed dispersers help plants to escape global warming

Juan P. González-Varo, José V. López-Bao & José Guitián
Plants are shifting their ranges towards higher elevations in response to global warming, yet such shifts are occurring at a rate slower than is needed to keep pace with a rapidly changing climate. There is, however, an almost complete lack of knowledge on seed dispersal across altitude, a key process to understand what constrains climate-driven range shifts. Here, we report the first direct empirical evidence on altitudinal seed dispersal mediated by two common frugivorous mammals:...

Data from: No evidence for maintenance of a sympatric Heliconius species barrier by chromosomal inversions

John W. Davey, Sarah L. Barker, Pasi M. Rastas, Ana Pinharanda, Simon H. Martin, Richard Durbin, W. Owen McMillan, Richard M. Merrill & Chris D. Jiggins
Mechanisms that suppress recombination are known to help maintain species barriers by preventing the breakup of coadapted gene combinations. The sympatric butterfly species Heliconius melpomene and Heliconius cydno are separated by many strong barriers, but the species still hybridize infrequently in the wild, and around 40% of the genome is influenced by introgression. We tested the hypothesis that genetic barriers between the species are maintained by inversions or other mechanisms that reduce between-species recombination rate....

Data from: Estimates of observer expertise improve species distributions from citizen science data

Alison Johnston, Daniel Fink, Wesley M Hochachka & Steve Kelling
1. Citizen science data are increasingly making valuable contributions to ecological studies. However, many citizen science surveys are also designed to encourage wide participation and therefore the participants have a range of natural history expertise, leading to variation and potentially bias in the data. 2. We assessed a recently proposed measure of observer expertise, calculated based on the average numbers of species recorded by observers. We investigated if this observer expertise score is associated with...

Data from: Global biogeographic patterns in bipolar moss species

Elisabeth Machteld Biersma, Jennifer A. Jackson, Jaakko Hyvonen, Satu Koskinen, Katrin Linse, Howard Griffiths & Peter Convey
A bipolar disjunction is an extreme, yet common, biogeographic pattern in non-vascular plants, yet its underlying mechanisms (vicariance or long-distance dispersal), origin and timing remain poorly understood. Here, combining a large-scale population dataset and multiple dating analyses, we examine the biogeography of four bipolar Polytrichales mosses, common to the Holarctic (temperate and polar Northern Hemisphere regions) and the Antarctic region (Antarctic, sub-Antarctic, southern South America) and other Southern Hemisphere (SH) regions. Our data reveal contrasting...

Data from: Simplifying understory complexity in oil palm plantations is associated with a reduction in the density of a cleptoparasitic spider, Argyrodes miniaceus (Araneae: Theridiidae), in host (Araneae: Nephilinae) webs

Dakota M. Spear, William A. Foster, Andreas Dwi Advento, Mohammad Naim, Jean-Pierre Caliman, Sarah H. Luke, Jake L. Snaddon, Sudharto Ps & Edgar C. Turner
Expansion of oil palm agriculture is currently one of the main drivers of habitat modification in Southeast Asia. Habitat modification can have significant effects on biodiversity, ecosystem function, and interactions between species by altering species abundances or the available resources in an ecosystem. Increasing complexity within modified habitats has the potential to maintain biodiversity and preserve species interactions. We investigated trophic interactions between Argyrodes miniaceus, a cleptoparasitic spider, and its Nephila spp. spider hosts in...

Data from: Small carbonaceous fossils (SCFs) from the Terreneuvian (lower Cambrian) of Baltica

Ben J. Slater, Thomas HP Harvey, Nicholas J. Butterfield & Thomas H. P. Harvey
We describe a new assemblage of small carbonaceous fossils (SCFs) from diagenetically minimally altered clays and siltstones of Terreneuvian age from the Lontova and Voosi formations of Estonia, Lithuania and Russia. This is the first detailed account of an SCF assemblage from the Terreneuvian, and includes a number of previously undocumented Cambrian organisms. Recognisably bilaterian-derived SCFs include abundant protoconodonts (total-group Chaetognatha), and distinctive cuticular spines of scalidophoran worms. Alongside these metazoan remains are a range...

Data from: Multi-jawed chaetognaths from the Chengjiang Lagerstätte (Cambrian, Series 2, Stage 3) of Yunnan, China

Degan Shu, Simon Conway Morris, Jian Han, Jennifer F. Hoyal Cuthill, Zhifei Zhang, Meirong Cheng & Hai Huang
Chaetognaths (arrow-worms) are enigmatic in terms of their phylogenetic position, while the existence of Protosagitta spinosa from the Chengjiang Lagerstätte suggests minimal change in their unique bodyplan since at least the early Cambrian. Apart from rare (and sometimes controversial) soft-bodied remains, the fossil record of chaetognaths is otherwise almost entirely dependent on early Palaeozoic phosphatic microfossils, some of which are placed amongst so-called protoconodonts. Fused spine clusters are strikingly similar to the cephalic grasping apparatus...

Data from: Sexual selection and population divergence II. divergence in different sexual traits and signal modalities in field crickets (Teleogryllus oceanicus)

Sonia Pascoal, Magdalena Mendrok, Alastair J. Wilson, John Hunt & Nathan W. Bailey
Sexual selection can target many different types of traits. However, the relative influence of different sexually-selected traits during evolutionary divergence is poorly understood. We used the field cricket Teleogryllus oceanicus to quantify and compare how five traits from each of three sexual signal modalities and components diverge among allopatric populations: male advertisement song, cuticular hydrocarbon (CHC) profiles and forewing morphology. Population divergence was unexpectedly consistent: we estimated the among-population (genetic) variance-covariance matrix, D, for all...

Data from: RAD sequencing resolves fine-scale population structure in a benthic invertebrate: implications for understanding phenotypic plasticity

David L.J. Vendrami, Luca Telesca, Hannah Weigand, Martina Weiss, Katie Fawcett, Katrin Lehman, Melody S. Clark, Florian Leese, Carrie McMinn, Heather Moore & Joseph I. Hoffman
The field of molecular ecology is transitioning from the use of small panels of classical genetic markers such as microsatellites to much larger panels of single nucleotide polymorphisms (SNPs) generated by approaches like RAD sequencing. However, few empirical studies have directly compared the ability of these methods to resolve population structure. This could have implications for understanding phenotypic plasticity, as many previous studies of natural populations may have lacked the power to detect genetic differences,...

Data from: An early chondrichthyan and the evolutionary assembly of a shark body plan

Michael I. Coates, John A. Finarelli, Ivan J. Sansom, Plamen S. Andreev, Katharine E. Criswell, Kristen Tietjen, Mark L. Rivers & Patrick J. La Riviere
Although relationships among the major groups of living gnathostomes are well established, the relatedness of early jawed vertebrates to modern clades is intensely debated. Here, we provide a new description of Gladbachus, a Middle Devonian (Givetian ~385-million-year-old) stem chondrichthyan from Germany, and one of the very few early chondrichthyans in which substantial portions of the endoskeleton are preserved. Tomographic and histological techniques reveal new details of the gill skeleton, hyoid arch and jaws, neurocranium, cartilage,...

Above-ground carbon density derived from LiDAR data over oil palm plantations in Malaysian Borneo, 2014

M.H. Nunes, R.M. Ewers, E.C. Turner & D.A. Coomes
This data set provides above-ground carbon density derived from LiDAR data over oil palm plantations in the Stability of Altered Forest Ecosystems (SAFE) project site located in Sabah, Malaysian Borneo in 2014. This includes the number of trees in plots and the average forest canopy per hectare at different heights. Data were collected during a project which was included in the NERC Human-modified tropical forest (HMTF) Programme.

Foraging behaviour of Parus major held in temporary captivity

R Thorogood, H Kokko & J Mappes
The data set describes foraging decisions by great tits (Parus major), held in temporary captivity. Data were collected from birds caught from forest at the University of Jyväskylä Research Station, Konnevesi (62°37.7'N 026°17'E), Finland, and were collected during the winter of 2013-2014. Birds were presented with (1) two different coloured plastic cups, or (2) two different artificial prey (almond pieces inside a paper packet and printed with a black and white symbol). One symbol was...

Data from: Empirical phylogenies and species abundance distributions are consistent with pre-equilibrium dynamics of neutral community models with gene flow

Anne-Sophie Bonnet-Lebrun, Andrea Manica, Anders Eriksson, Ana S.L. Rodrigues & Ana S. L. Rodrigues
Community characteristics reflect past ecological and evolutionary dynamics. Here, we investigate whether it is possible to obtain realistically shaped modelled communities – i.e., with phylogenetic trees and species abundance distributions shaped similarly to typical empirical bird and mammal communities – from neutral community models. To test the effect of gene flow, we contrasted two spatially explicit individual-based neutral models: one with protracted speciation, delayed by gene flow, and one with point mutation speciation, unaffected by...

Data from: Does coevolution with a shared parasite drive hosts to partition their defences among species?

Eleanor M. Caves, Martin Stevens & Claire N. Spottiswoode
When mimicry imposes costs on models, selection may drive the model's phenotype to evolve away from its mimic. For example, brood parasitism often drives hosts to diversify in egg appearance among females within a species, making mimetic parasitic eggs easier to detect. However, when a single parasite species exploits multiple host species, parasitism could also drive host egg evolution away from other co-occurring hosts, to escape susceptibility to their respective mimics. This hypothesis predicts that...

Data from: Is bigger better? The relationship between size and reproduction in female Asian elephants

J. A. H. Crawley, H. S. Mumby, S. N. Chapman, M. Lahdenperä, K. U. Mar, W. Htut, A. Thura Soe, H. H. Aung & V. Lummaa
The limited availability of resources is predicted to impose trade-offs between growth, reproduction and self-maintenance in animals. However, although some studies have shown that early reproduction suppresses growth, reproduction positively correlates with size in others. We use detailed records from a large population of semi-captive elephants in Myanmar to assess the relationships between size (height and weight), reproduction and survival in female Asian elephants, a species characterized by slow, costly life history. Although female height...

Data from: Disparity, diversity, and duplications in the Caryophyllales

Stephen A. Smith, Joseph W. Brown, Ya Yang, Riva Bruenn, Chloe P. Drummond, Samuel F. Brockington, Joseph F. Walker, Noah Last, Norman A. Douglas & Michael J. Moore
The role played by whole genome duplication (WGD) in plant evolution is actively debated. WGDs have been associated with advantages such as superior colonization, various adaptations, and increased effective population size. However, the lack of a comprehensive mapping of WGDs within a major plant clade has led to uncertainty regarding the potential association of WGDs and higher diversification rates. Using seven chloroplast and nuclear ribosomal genes, we constructed a phylogeny of 5036 species of Caryophyllales,...

Data from: Bird and bat species' global vulnerability to collision mortality at wind farms revealed through a trait-based assessment

Chris B. Thaxter, Graeme M. Buchanan, Carr Jamie, Stuart H.M. Butchart, Tim Newbold, Rhys E. Green, Joseph A. Tobias, Wendy B. Foden, Sue O'Brien & James W. Pearce-Higgins
Mitigation of anthropogenic climate change involves deployments of renewable energy worldwide, including wind farms, which can pose a significant collision risk to volant animals. Most studies into the collision risk between species and wind turbines, however, have taken place in industrialized countries. Potential effects for many locations and species therefore remain unclear. To redress this gap, we conducted a systematic literature review of recorded collisions between birds and bats and wind turbines within developed countries....

Data from: Improved transcriptome sampling pinpoints 26 ancient and more recent polyploidy events in Caryophyllales, including two allopolyploidy events

Ya Yang, Michael J. Moore, Samuel F. Brockington, Jessica Mikenas, Julia Olivieri, Joseph F. Walker & Stephen A. Smith
• Studies of the macroevolutionary legacy of polyploidy are limited by an incomplete sampling of these events across the tree of life. To better locate and understand these events, we need comprehensive taxonomic sampling as well as homology inference methods that accurately reconstruct the frequency and location of gene duplications. • We assembled a dataset of transcriptomes and genomes from 169 species in Caryophyllales, of which 43 were newly generated for this study, representing one...

Data from: Resolving recent plant radiations: power and robustness of genotyping-by-sequencing

Mario Fernández-Mazuecos, Greg Mellers, Beatriz Vigalondo, Llorenç Sáez, Pablo Vargas & Beverley J. Glover
Disentangling species boundaries and phylogenetic relationships within recent evolutionary radiations is a challenge due to the poor morphological differentiation and low genetic divergence between species, frequently accompanied by phenotypic convergence, inter-specific gene flow and incomplete lineage sorting. Here we employed a genotyping-by-sequencing (GBS) approach, in combination with morphometric analyses, to investigate a small western Mediterranean clade in the flowering plant genus Linaria that radiated in the Quaternary. After confirming the morphological and genetic distinctness of...

Data from: When do trade-offs occur? The roles of energy constraints and trait flexibility in a bushcricket

Flavia Barbosa, Darren Rebar & Michael D. Greenfield
In many animal species, the expression of sexually-selected traits is negatively correlated with survival traits such as immune function, a relationship termed a ‘trade-off’. But an alternative in which sexually-selected traits are positively correlated with survival traits is also widespread. The nature of inter-trait relationships may be largely determined by overall energy expenditure, energy availability, and trait flexibility, with trade-offs expected when individuals are subject to energy constraints. We tested this hypothesis in Ephippiger diurnus,...

Field spectroscopy and leaf trait data from a field experiment in Surrey [HMTF]

D.A. Coomes, M. Davey & M.H. Nunes
The dataset comprises a range of leaf traits, measured from leaf samples collected from trees growing on deep alluvial soils and shallow chalk soils, near Mickleham in Surrey, UK. Across both sites, leaves were collected from 66 trees, representing six species. The six species common to both sites were: Acer campestre (field maple), Acer pseudoplatanus (sycamore), Corylus avellana (hazel), Crataegus monogyna (hawthorn), Fraxinus excelsior (ash) and Sambucus nigra (elder). Data were collected under the NERC...

Data from: Why on earth did I buy that? A study of regretted appliance purchases

Thomas Roberts, Aimie Hope & Alexandra Skelton
If targets to reduce greenhouse gas emissions and thereby tackle climate change are to be achieved, it will be necessary to reduce both embodied energy costs (e.g. in terms of producing and manufacturing the products and services that society consumes) and operational energy costs. Reducing the number of purchases that people regret could be a first step in changing the overall dynamic of consumption patterns. This research looks at some potentially adverse effects of consumption...
