Data from: Payoff-based learning explains the decline in cooperation in public goods games

Maxwell N. Burton-Chellew, Heinrich H. Nax, Stuart A. West, M. N. Burton-Chellew & S. A. West
Economic games such as the public goods game are increasingly being used to measure social behaviours in humans and non-human primates. The results of such games have been used to argue that people are pro-social, and that humans are uniquely altruistic, willingly sacrificing their own welfare in order to benefit others. However, an alternative explanation for the empirical observations is that individuals are mistaken, but learn, during the game, how to improve their personal payoff....

Data from: Impacts of selective logging on inbreeding and gene flow in two Amazonian timber species with contrasting ecological and reproductive characteristics

Christina C. Vinson, Milton Kanashiro, Stephen A. Harris, Dave H. Boshier, C. C. Vinson, S. A. Harris & D. H. Boshier
Selective logging in Brazil allows for the removal of up to 90% of trees above 50 cm diameter of a given timber species, independent of a species’ life history characteristics or how quickly it will recover. The genetic and demographic effects of selective logging on two Amazonian timber species (Dipteryx odorata Leguminosae, Jacaranda copaia Bignoniaceae) with contrasting ecological and reproductive characteristics were assessed in the same forest. Genetic diversity and gene flow were characterized by...

Data from: strap: an R package for plotting phylogenies against stratigraphy and assessing their stratigraphic congruence

Mark A. Bell & Graeme T. Lloyd
strap (Stratigraphic Tree Analysis for Palaeontology) is a new package for the freely available statistical programming language R designed to perform three main tasks: (1) to time-scale phylogenies of fossil taxa; (2) to plot those time-scaled trees against stratigraphy; and (3) to assess congruence between phylogenies and stratigraphy. Time-scaling is performed with the DatePhylo function, with three approaches offered. Plotting trees against a choice of five different geological time scaless is possible using the geoscalePhylo...

Data from: Linking system-wide impacts of RNA polymerase mutations to the fitness cost of rifampin resistance in Pseudomonas aeruginosa

Qin Qi, Gail M. Preston & R. Craig MacLean
Fitness costs play a key role in the evolutionary dynamics of antibiotic resistance in bacteria by generating selection against resistance in the absence of antibiotics. Although the genetic basis of antibiotic resistance is well understood, the precise molecular mechanisms linking the genetic basis of resistance to its fitness cost remain poorly characterized. Here, we examine how the system-wide impacts of mutations in the RNA polymerase (RNAP) gene rpoB shape the fitness cost of rifampin resistance...

Data from: Dispersal and the transition to sympatry in vertebrates

Alex L. Pigot, Joseph A. Tobias, A. L. Pigot & J. A. Tobias
Under allopatric speciation models, a key step in the build-up of species richness is population dispersal leading to the co-occurrence of previously geographically isolated forms. Despite its central importance for community assembly, the extent to which the transition from spatial segregation (allopatry or parapatry) to coexistence (sympatry) is a predictable process, or alternatively one governed by chance and the vagaries of biogeographic history, remains poorly understood. Here, we use estimated divergence times and current patterns...

Data from: Establishing macroecological trait datasets: digitalization, extrapolation, and validation of diet preferences in terrestrial mammals worldwide

Wilm Daniel Kissling, Lars Dalby, Camilla Fløjgaard, Jonathan Lenoir, Brody Sandel, Christopher Sandom, Kristian Trøjelsgaard, Jens-Christian Svenning & Jens-Christian Svenning
Ecological trait data are essential for understanding the broad-scale distribution of biodiversity and its response to global change. For animals, diet represents a fundamental aspect of species’ evolutionary adaptations, ecological and functional roles, and trophic interactions. However, the importance of diet for macroevolutionary and macroecological dynamics remains little explored, partly because of the lack of comprehensive trait datasets. We compiled and evaluated a comprehensive global dataset of diet preferences of mammals (“MammalDIET”). Diet information was...

Data from: Range-wide multilocus phylogeography of the red fox reveals ancient continental divergence, minimal genomic exchange, and distinct demographic histories

Mark J. Statham, Zhenghuan Wang, Carl D. Soulsbury, Jan Janecka, Benjamin N. Sacks, Keith B. Aubry, Oliver Berry, Ceiridwen J. Edwards & James Murdoch
Widely distributed taxa provide an opportunity to compare biogeographic responses to climatic fluctuations on multiple continents and to investigate speciation. We conducted the most geographically and genomically comprehensive study to date of the red fox (Vulpes vulpes), the world's most widely distributed wild terrestrial carnivore. Analyses of 697 bp of mitochondrial sequence in ~1000 individuals suggested an ancient Middle Eastern origin for all extant red foxes and a 400 kya (SD = 139 kya) origin...

Data from: The genetic basis of the fitness costs of antimicrobial resistance: a meta-analysis approach

Tom Vogwill & R. Craig MacLean
The evolution of antibiotic resistance carries a fitness cost, expressed in terms of reduced competitive ability in the absence of antibiotics. This cost plays a key role in the dynamics of resistance by generating selection against resistance when bacteria encounter an antibiotic-free environment. Previous work has shown that the cost of resistance is highly variable, but the underlying causes remain poorly understood. Here, we use a meta-analysis of the published resistance literature to determine how...

Data from: Pathogen burden, co-infection and major histocompatibility complex variability in the European badger (Meles meles)

Yung Wa Sin, Geetha Annavi, Hannah L. Dugdale, Chris Newman, Terry Burke & David W. Macdonald
Pathogen-mediated selection is thought to maintain the extreme diversity in the major histocompatibility complex (MHC) genes, operating through the heterozygote advantage, rare-allele advantage and fluctuating selection mechanisms. Heterozygote advantage (i.e., recognizing and binding a wider range of antigens than homozygotes) is expected to be more detectable when multiple pathogens are considered simultaneously. Here, we test if MHC diversity in a wild population of European badgers (Meles meles) is driven by pathogen-mediated selection. We examined individual...

Data from: The importance of microhabitat for biodiversity sampling

Zia Mehrabi, Eleanor M. Slade, Angel Solis & Darren J. Mann
Responses to microhabitat are often neglected when ecologists sample animal indicator groups. Microhabitats may be particularly influential in non-passive biodiversity sampling methods, such as baited traps or light traps, and for certain taxonomic groups which respond to fine scale environmental variation, such as insects. Here we test the effects of microhabitat on measures of species diversity, guild structure and biomass of dung beetles, a widely used ecological indicator taxon. We demonstrate that choice of trap...

Data from: Virtual reconstruction of endocast anatomy in early ray-finned fishes (Osteichthyes: Actinopterygii)

Sam Giles & Matt Friedman
Cranial endocasts, infillings of the skeletal void that once contained the brain and associated soft tissues, represent detailed anatomical structures that have long been the focus of paleontological investigation. We applied computed tomographics (CTs) in order to generate endocast models for the Paleozoic actinopterygian fishes Mimipiscis and Kentuckia, which serve as key representatives of anatomically primitive, early ray fins in analyses of early vertebrate relationships. The resultant endocranial models generally corroborate existing accounts of endocranial...

Data from: Heterozygosity–fitness correlations in a wild mammal population: accounting for parental and environmental effects

Geetha Annavi, Chris Newman, Christina D. Buesching, David W. Macdonald, Terry Burke, Hannah L. Dugdale & Christopher Newman
HFCs (heterozygosity–fitness correlations) measure the direct relationship between an individual's genetic diversity and fitness. The effects of parental heterozygosity and the environment on HFCs are currently under-researched. We investigated these in a high-density U.K. population of European badgers (Meles meles), using a multimodel capture–mark–recapture framework and 35 microsatellite loci. We detected interannual variation in first-year, but not adult, survival probability. Adult females had higher annual survival probabilities than adult males. Cubs with more heterozygous fathers...

Data from: An experimental study of strong reciprocity in bacteria

R. Fredrik Inglis, Stuart West, Angus Buckling, A. Buckling & S. West
Strong reciprocity, whereby cooperators punish non-cooperators, may help to explain the evolutionary success of cooperative behaviours. However, theory suggests that selection for strong reciprocity can depend upon tight genetic linkage between cooperation and punishment, to avoid the strategy being outcompeted by non-punishing cooperators. We tested this hypothesis using experimental populations of the bacterium Pseudomonas aeruginosa, which cooperate by producing iron-scavenging siderophores and, in this context, punish non-cooperators with toxins. Consistent with theory, we show that...

Data from: A Silurian short-great-appendage arthropod

Derek J. Siveter, Derek E. G. Briggs, David J. Siveter, Mark D. Sutton, David J. Legg, Sarah Joomun, D. E. G. Briggs, D. Legg, M. D. Sutton, S. Joomun & D. J. Siveter
A new arthropod, Enalikter aphson gen. et sp. nov., is described from the Silurian (Wenlock Series) Herefordshire Lagerstätte of the UK. It belongs to the Megacheira (=short-great-appendage group), which is recognized here, for the first time, in strata younger than mid-Cambrian age. Discovery of this new Silurian taxon allows us to identify a Devonian megacheiran representative, Bundenbachiellus giganteus from the Hunsrück Slate of Germany. The phylogenetic position of megacheirans is controversial: they have been interpreted...

Data from: Efficient inference of recombination hot regions in bacterial genomes

Koji Yahara, Xavier Didelot, M Azim. Ansari, Samuel K. Sheppard & Daniel Falush
In eukaryotes, detailed surveys of recombination rates have shown variation at multiple genomic scales and the presence of “hotspots” of highly elevated recombination. In bacteria, studies of recombination rate variation are less developed, in part because there are few analysis methods that take into account the clonal context within which bacterial evolution occurs. Here we focus in particular on identifying “hot regions” of the genome where DNA is transferred frequently between isolates. We present a...

High-resolution global topographic index values

T.R. Marthews, S.J. Dadson, B. Lehner, S. Abele & N. Gedney
The topographic index is a hydrological quantity describing the propensity of the soil at landscape points to become saturated with water as a result of topographic position (i.e. not accounting for other factors such as climate that also affect soil moisture but are accounted for separately). Modern land surface models require a characterisation of the land surface hydrological regime and this parameter allows the use of the TOPMODEL hydrological model to achieve this .This Geographic...

High-resolution hydraulic parameter maps for surface soils in tropical South America

T. Marthews, C.A. Quesada, D.R. Galbraith, Y. Malhi, C.E. Mullins, M.G. Hodnett & I. Dharssi
Spatial data files holding gridded parameter maps of surface soil hydraulic parameters derived from a selection of pedotransfer functions. Modern land surface model simulations capture soil profile water movement through the use of soil hydraulics sub-models, but good hydraulic parameterisations are often lacking - especially in the tropics - and it is this lack that we fill here in the context of South America. Optimal hydraulic parameter values are given for the Brooks and Corey,...

Data from: Sex and boldness explain individual differences in spatial learning in a lizard

Pau Carazo, Daniel W. A. Noble, Dani Chandrasoma, Martin J. Whiting, D. Chandrasoma, D. W. A. Noble, M. J. Whiting & P. Carazo
Understanding individual differences in cognitive performance is a major challenge to animal behaviour and cognition studies. We used the Eastern water skink (Eulamprus quoyii) to examine associations between exploration, boldness and individual variability in spatial learning, a dimension of lizard cognition with important bearing on fitness. We show that males perform better than females in a biologically relevant spatial learning task. This is the first evidence for sex differences in learning in a reptile, and...

Data from: Evolution of paternal care in diploid and haplodiploid populations

Nicholas G. Davies, Andy Gardner, A. Gardner & N. G. Davies
W. D. Hamilton famously suggested that the inflated relatedness of full sisters under haplodiploidy explains why all workers in the social hymenoptera are female. This suggestion has not stood up to further theoretical scrutiny and is not empirically supported. Rather, it appears that altruistic sib-rearing in the social hymenoptera is performed exclusively by females because this behaviour has its origins in parental care, which was performed exclusively by females in the ancestors of this insect...

Data from: Neighbouring-group composition and within-group relatedness drive extra-group paternity rate in the European badger (Meles meles)

Geetha Annavi, Chris Newman, Hannah L. Dugdale, Christina C. Buesching, Yung W. Sin, Terry Burke, David W. Macdonald, H. L. Dugdale, G. Annavi, C. Newman, C. D. Buesching, Y. W. Sin, D. W. Macdonald & T. Burke
Extra-group paternity (EGP) occurs commonly among group-living mammals and plays an important role in mating systems and the dynamics of sexual selection; however, socio-ecological and genetic correlates of EGP have been underexplored. We use 23 years of demographic and genetic data from a high-density European badger (Meles meles) population, to investigate the relationship between the rate of EGP in litters and mate availability, mate incompatibility and mate quality (heterozygosity). Relatedness between within-group assigned mothers and...

Data from: Multi-serotype pneumococcal nasopharyngeal carriage prevalence in vaccine naïve Nepalese children, assessed using molecular serotyping.

Rama Kandasamy, Meeru Gurung, Anushil Thapa, Susan Ndimah, Neelam Adhikari, David R. Murdoch, Dominic F. Kelly, Denise E. Waldron, Katherine A. Gould, Stephen Thorson, Shrijana Shrestha, Jason Hinds & Andrew J. Pollard
Invasive pneumococcal disease is one of the major causes of death in young children in resource poor countries. Nasopharyngeal carriage studies provide insight into the local prevalence of circulating pneumococcal serotypes. There are very few data on the concurrent carriage of multiple pneumococcal serotypes. This study aimed to identify the prevalence and serotype distribution of pneumococci carried in the nasopharynx of young healthy Nepalese children prior to the introduction of a pneumococcal conjugate vaccine using...

Data from: Preference for outbred host plants and positive effects of inbreeding on egg survival in a specialist herbivore

Aino Kalske, Anne Muola, Pia Mutikainen, Roosa Leimu, A. Muola, A. Kalske & R. Leimu
Inbreeding can profoundly affect the interactions of plants with herbivores as well as with the natural enemies of the herbivores. We studied how plant inbreeding affects herbivore oviposition preference, and whether inbreeding of both plants and herbivores alters the probability of predation or parasitism of herbivore eggs. In a laboratory preference test with the specialist herbivore moth Abrostola asclepiadis and inbred and outbred Vincetoxicum hirundinaria plants, we discovered that herbivores preferred to oviposit on outbred...

Data from: Population-level effects of fitness costs associated with repressible female-lethal transgene insertions in two pest insects

Tim Harvey-Samuel, Thomas Ant, Neil Morrison, Hongfei Gong & Luke Alphey
Genetic control strategies offer great potential for the sustainable and effective control of insect pests. These strategies involve the field release of transgenic insects with the aim of introducing engineered alleles into wild populations, either permanently or transiently. Their efficacy can therefore be reduced if transgene-associated fitness costs reduce the relative performance of released insects. We describe a method of measuring the fitness costs associated with transgenes by analyzing their evolutionary trajectories when placed in...

Data from: Diet quality in a wild grazer declines under the threat of an ambush predator

Florian Barnier, Marion Valeix, Patrick Duncan, Simon Chamaillé-Jammes, Philippe Barre, Andrew J. Loveridge, David W. Macdonald, Hervé Fritz, A. J. Loveridge, D. W. Macdonald, M. Valeix, F. Barnier, P. Duncan, H. Fritz, P. Barre & S. Chamaille-Jammes
Predators influence prey populations not only through predation itself, but also indirectly through prompting changes in prey behaviour. The behavioural adjustments of prey to predation risk may carry nutritional costs, but this has seldom been studied in the wild in large mammals. Here, we studied the effects of an ambush predator, the African lion (Panthera leo), on the diet quality of plains zebras (Equus quagga) in Hwange National Park, Zimbabwe. We combined information on movements...

Data from: Colour in a new light: a spectral perspective on the quantitative genetics of carotenoid coloration

Simon R. Evans & Ben C. Sheldon
1. Carotenoid-based colours are model traits for research on animal signalling and sexual selection but, whereas the consequences of variable expression have been extensively studied, its causes are rarely quantified. This issue is complicated by the composite nature of carotenoid-based colour patches, which combine pigments and a reflective background. Ultimately, the evolution of such colours will be determined by the processes that govern variable expression of these mechanisms. 2. We present a novel approach to...
