Invertebrate activity data from an experiment in Malaysian Borneo, 2014-16 [HMTF]

H.M. Griffiths, L.A. Ashton, A.E. Walker, R. Hasan, T. Evans, P. Eggleton & C.L. Parr
This resource comprises a time series dataset of ant and other invertebrate abundance measured fortnightly at bait monitoring cards on an experimental plot in the Maliau Basin Conservation Area, Malaysian Borneo. The resource includes data regarding the amount of food resource removed from experimental plots when either ants or vertebrates were excluded from the resource. The data were collected to assess the roles that the different groups (ants, invertebrates, vertebrates) play in ecosystem function, and...

Data from: Continent-level drivers of African pyrodiversity

Gareth P. Hempson, Catherine L. Parr, Sally Archibald, T. Michael Anderson, Colin J. Courtney Mustaphi, Andrew P. Dobson, Jason E. Donaldson, Thomas A. Morrison, James Probert & Colin M. Beale
Pyrodiversity, which describes fire variability over space and time, is believed to increase habitat heterogeneity and thereby promote biodiversity. However, to date there is no standardised metric for quantifying pyrodiversity, and so broad geographic patterns and drivers of pyrodiversity remain unexplored. We present the first generalizable method to quantify pyrodiversity, and use it to address the fundamental questions of what drives pyrodiversity, which fire attributes constrain pyrodiversity under different conditions, and whether pyrodiversity is spatial...

Data from: Insect temperature-body size trends common to laboratory, latitudinal and seasonal gradients are not found across altitudes

Curtis R. Horne, Andrew G. Hirst & David Atkinson
1. Body size affects rates of most biological and ecological processes, from individual performance to ecosystem function, and is fundamentally linked to organism fitness. Within species, size at maturity can vary systematically with environmental temperature in the laboratory and across seasons, as well as over latitudinal gradients. Recent meta-analyses have revealed a close match in the magnitude and direction of these size gradients in various arthropod orders, suggesting that these size responses share common drivers....

Data from: Explaining ecological shifts: the roles of temperature and primary production in the long-term dynamics of benthic faunal composition

David S. Clare, Matthew Spencer, Leonie A. Robinson, Christopher L.J. Frid & Christopher L. J. Frid
Predicting the ecological consequences of environmental change requires that we can identify the drivers of long-term ecological variation. Biological assemblages can exhibit abrupt deviations from temporal trends, potentially resulting in irreversible shifts in species composition over short periods of time. Such dynamics are hypothesised to occur as gradual forcing eventually causes biological thresholds to be crossed, but could also be explained by biota simply tracking abrupt changes to their environment. Here, we modelled temporal variation...

Data from: Boldness predicts an individual's position along an exploration-exploitation foraging trade-off

Samantha C. Patrick, David Pinaud & Henri Weimerskirch
Individuals do not have complete information about the environment and therefore they face a trade-off between gathering information (exploration) and gathering resources (exploitation). Studies have shown individual differences in components of this trade-off but how stable these strategies are in a population and the intrinsic drivers of these differences is not well understood. Top marine predators are expected to experience a particularly strong trade-off as many species have large foraging ranges and their prey often...

Data from: Effect of the early social environment on behavioural and genomic responses to a social challenge in a cooperatively breeding vertebrate

Cecilia Nyman, Stefan Fischer, Nadia Aubin-Horth & Barbara Taborsky
The early social environment can have substantial, lifelong effects on vertebrate social behaviour, which can be mediated by developmental plasticity of brain gene expression. Early life effects can influence immediate behavioural responses towards later-life social challenges and can activate different gene expression responses. However, while genomic responses to social challenges have been reported frequently, how developmental experience influences the shape of these genomic reaction norms remains largely unexplored. We tested how manipulating the early social...

Data from: Ranking and characterization of established BMI and lipid associated loci as candidates for gene-environment interactions

Dmitry Shungin, Wei Q. Deng, Tibor V. Varga, Jian'an Luan, Evelin Mihailov, Andres Metspalu, Andrew P. Morris, Nita G. Forouhi, Cecilia Lindgren, Patrik K. E. Magnusson, Nancy L. Pedersen, Göran Hallmans, Audrey Y. Chu, Anne E. Justice, Mariaelisa Graff, Thomas W. Winkler, Lynda M. Rose, Claudia Langenberg, L. Adrienne Cupples, Paul M. Ridker, Nicholas J. Wareham, Ken K. Ong, Ruth J. F. Loos, Daniel I. Chasman, Erik Ingelsson … & Paul W. Franks
Phenotypic variance heterogeneity across genotypes at a single nucleotide polymorphism (SNP) may reflect underlying gene-environment (G·E) or gene-gene interactions. We modeled variance heterogeneity for blood lipids and BMI in up to 44,211 participants and investigated relationships between variance effects (Pv), G·E interaction effects (with smoking and physical activity), and marginal genetic effects (Pm). Correlations between Pv and Pm were stronger for SNPs with established marginal effects (Spearman's ρ=0.401 for triglycerides, and ρ=0.236 for BMI) compared...

Data from: Experimental investigation of alternative transmission functions: quantitative evidence for the importance of non-linear transmission dynamics in host-parasite systems

Sarah A. Orlofske, Samuel M. Flaxman, Maxwell B. Joseph, Andy Fenton, Brett A. Melbourne & Pieter T. J. Johnson
1. Understanding pathogen transmission is crucial for predicting and managing disease. Nonetheless, experimental comparisons of alternative functional forms of transmission remain rare, and those experiments that are conducted are often not designed to test the full range of possible forms. 2. To differentiate among ten candidate transmission functions, we used a novel experimental design in which we independently varied four factors—duration of exposure, numbers of parasites, numbers of hosts, and parasite density—in laboratory infection experiments....

Data from: Conflicting selection alters the trajectory of molecular evolution in a tripartite bacteria–plasmid–phage interaction

Ellie Harrison, James Hall, Steve Paterson, Andrew Spiers, Michael Brockhurst, James P. J. Hall & Michael A. Brockhurst
Bacteria engage in a complex network of ecological interactions, which includes mobile genetic elements (MGEs) such as phages and plasmids. These elements play a key role in microbial communities as vectors of horizontal gene transfer but can also be important sources of selection for their bacterial hosts. In natural communities, bacteria are likely to encounter multiple MGEs simultaneously and conflicting selection among MGEs could alter the bacterial evolutionary response to each MGE. Here, we test...

Data from: From the animal house to the field: are there consistent individual differences in immunological profile in wild populations of field voles (Microtus agrestis)?

Elena Arriero, Klara M. Wanelik, Richard J. Birtles, Janette E. Bradley, Joseph A. Jackson, Steve Paterson & Mike Begon
Inbred mouse strains, living in simple laboratory environments far removed from nature, have been shown to vary consistently in their immune response. However, wildlife populations are typically outbreeding and face a multiplicity of challenges, parasitological and otherwise. In this study we seek evidence of consistent difference in immunological profile amongst individuals in the wild. We apply a novel method in this context, using longitudinal (repeated capture) data from natural populations of field voles, Microtus agrestis,...

Data from: The evolution of costly mate choice against segregation distorters

Andri Manser, Anna K. Lindholm, Franjo J. Weissing & Franz J. Weissing
The evolution of female preference for male genetic quality remains a controversial topic in sexual selection research. One well-known problem, known as the lek paradox, lies in understanding how variation in genetic quality is maintained in spite of natural selection and sexual selection against low-quality alleles. Here, we theoretically investigate a scenario where females pay a direct fitness cost to avoid males carrying an autosomal segregation distorter. We show that preference evolution is greatly facilitated...

Data from: Advancing Precambrian palaeomagnetism with the PALEOMAGIA and PINT(QPI) databases

Toni H. Veikkolainen, Andrew J. Biggin, Lauri J. Pesonen, David A. Evans & Nicholas A. Jarboe
State-of-the-art measurements of the direction and intensity of Earth’s ancient magnetic field have made important contributions to our understanding of the geology and palaeogeography of Precambrian Earth. The PALEOMAGIA and PINT(QPI) databases provide thorough public collections of important palaeomagnetic data of this kind. They comprise more than 4,100 observations in total and have been essential in supporting our international collaborative efforts to understand Earth's magnetic history on a timescale far longer than that of the...

Data from: The interaction of fatigue cracks with a residual stress field using thermoelastic stress analysis and synchrotron x-ray diffraction experiments

Khurram Amjad, David Asquith, Eann A. Patterson, Christopher M. Sebastian & Wei-Chung Wang
This article presents an experimental study on the fatigue behaviour of cracks emanating from cold-expanded holes utilising thermoelastic stress analysis (TSA) and synchrotron x-ray diffraction (SXRD) techniques with the aim of resolving the long-standing ambiguity in the literature regarding potential relaxation, or modification, of beneficial compressive residual stresses as a result of fatigue crack propagation. The crack growth rates are found to be substantially lower as the crack tip moved through the residual stress zone...

Data from: High virulence sub-populations in Pseudomonas aeruginosa long-term cystic fibrosis airway infections

Siobhan O'Brien, David Williams, Joanne L. Fothergill, Steve Paterson, Winstanley Craig & Michael A. Brockhurst
Background: Pseudomonas aeruginosa typically displays loss of virulence-associated secretions over the course of chronic cystic fibrosis infections. This has led to the suggestion that virulence is a costly attribute in chronic infections. However, previous reports suggest that overproducing (OP) virulent pathotypes can coexist with non-producing mutants in the CF lung for many years. The consequences of such within-patient phenotypic diversity for the success of this pathogen are not fully understood. Here, we provide in-depth quantification...

Data from: Habitat disturbance selects against both small and large species across varying climates

Heloise Gibb, Nathan J. Sanders, Robert R. Dunn, Xavier Arnan, Heraldo L. Vasconcellos, David A. Donoso, Alan N. Andersen, Rogerio R. Silva, Tom R. Bishop, Crisanto Gomez, Blair F. Grossman, Kalsum M. Yusah, Sarah H. Luke, Renata Pacheco, Jessica Pearce-Duvet, Javier Retana, Melanie Tista, Catherine L. Parr & H. L. Vasconcelos
Global extinction drivers, including habitat disturbance and climate change, are thought to affect larger species more than smaller species. However, it is unclear if such drivers interact to affect assemblage body size distributions. We asked how these two key global change drivers differentially affect the interspecific size distributions of ants, one of the most abundant and ubiquitous animal groups on earth. We also asked whether there is evidence of synergistic interactions and whether effects are...

Data from: Sperm competition suppresses gene drive among experimentally evolving populations of house mice

Andri Manser, Anna K. Lindholm, Leigh W. Simmons & Renée C. Firman
Drive genes are genetic elements that manipulate the 50% ratio of Mendelian inheritance in their own favour, allowing them to rapidly propagate through populations. The action of drive genes is often hidden, making detection and identification inherently difficult. Yet drive genes can have profound evolutionary consequences for the populations that harbour them: most known drivers are detrimental to organismal gamete development, reproduction and survival. In this study, we identified the presence of a well-known drive...

Data from: A test for paedomorphism in domestic pig cranial morphology

Allowen Evin, Joseph Owen, Greger Larson, Mélanie Debiais-Thibaud, Thomas Cucchi, Una Strand Vidarsdottir & Keith Dobney
Domestic animals are often described as paedomorphic, meaning that they retain juvenile characteristics into adulthood. Through a three-dimensional landmark-based geometric morphometric analysis of cranial morphology at three growth stages, we demonstrate that wild boar (n = 138) and domestic pigs (n = 106) (Sus scrofa) follow distinct ontogenetic trajectories. With the exception of the size ratio between facial and neurocranial regions, paedomorphism does not appear to be the primary pattern describing the observed differences between...

Data from: Routine habitat switching alters the likelihood and persistence of infection with a pathogenic parasite

David R. Daversa, Andrea Manica, Jaime Bosch, Jolle W. Jolles & Trenton W. J. Garner
1.Animals switch habitats on a regular basis, and when habitats vary in suitability for parasitism, routine habitat switching alters the frequency of parasite exposure and may affect post-infection parasite proliferation. However, the effects of routine habitat switching on infection dynamics are not well understood. 2.We performed infection experiments, behavioural observations, and field surveillance to evaluate how routine habitat switching by adult alpine newts (Ichthyosaura alpestris) influences infection dynamics of the pathogenic parasite, Batrachochytrium dendrobatidis (Bd)....

Data from: Dominance and the initiation of group feeding events: the modifying effect of sociality

Julian C. Evans, Teri B. Jones & Julie Morand-Ferron
Individuals can differ in how much they benefit from being in a group depending on characteristics such as their dominance rank or their behaviour. Understanding which categories of individuals influence the decisions of a group could help understand which individuals are benefiting the most. We examine these ideas in wild flocks of black-capped chickadees (Poecile atricapillus), which feature stable group membership and linear dominance hierarchies. We attempt to infer which individuals are influencing group movement...

Data from: Life-history strategy determines constraints on immune function

Benjamin James Parker, Seth M. Barribeau, Alice M. Laughton, Lynn H. Griffin & Nicole M. Gerardo
1) Determining the factors governing investment in immunity is critical for understanding host-pathogen ecological and evolutionary dynamics. Studies often consider disease resistance in the context of life-history theory, with the expectation that investment in immunity will be optimized in anticipation of disease risk. Immunity, however, is constrained by context-dependent fitness costs. How the costs of immunity vary across life-history strategies has yet to be considered. 2) Pea aphids are typically unwinged but produce winged offspring...

Data from: Sexual conflict and correlated evolution between male persistence and female resistance traits in the seed beetle Callosobruchus maculatus

Liam R. Dougherty, Emile Van Lieshout, Kathryn B. McNamara, Joe A. Moschilla, Göran Arnqvist & Leigh W. Simmons
Traumatic mating (or copulatory wounding) is an extreme form of sexual conflict whereby male genitalia physically harm females during mating. In such species females are expected to evolve counter-adaptations to reduce male-induced harm. Importantly, female counter-adaptations may include both genital and non-genital traits. In this study, we examine evolutionary associations between harmful male genital morphology and female reproductive tract morphology and immune function across 13 populations of the seed beetle Callosobruchus maculatus. We detected positive...

Data from: A comparative analysis of the behavioral response to fishing boats in two albatross species

Julien Collet, Samantha C. Patrick & Henri Weimerskirch
Anthropogenic food resources have significantly modified the foraging behavior of many animal species. They enhance large multi-specific aggregations of individuals, with strong ecological consequences. It is challenging to predict how individuals or species can differ in their reaction to these resources. For instance, there are wide variations in seabird species abundance behind fishing boats, and individual variations in interaction rates. Whether this is reflecting variations in fine-scale encounter rates or rather variations in attraction strength...

Data from: Effects of age and reproductive status on individual foraging site fidelity in a long-lived marine predator

Stephen C. Votier, Annette L. Fayet, Stuart Bearhop, Thomas W. Bodey, Bethany L. Clark, James Grecian, Tim Guilford, Keith C. Hamer, Jana W.E. Jeglinski, Greg Morgan, Ewan Wakefield, Samantha C. Patrick & Jana W. E. Jeglinski
Individual foraging specializations, where individuals use a small component of the population niche width, are widespread in nature with important ecological and evolutionary implications. In long-lived animals, foraging ability develops with age, but we know little about the ontogeny of individuality in foraging. Here we use precision global positioning system (GPS) loggers to examine how individual foraging site fidelity (IFSF), a common component of foraging specialization, varies between breeders, failed breeders and immatures in a...

Data from: Offspring development and life-history variation in a water flea depends upon clone-specific integration of genetic, non-genetic and environmental cues

Ewan Harney, Steve Paterson & Stewart J. Plaistow
1. Theory predicts that offspring developmental strategies involve the integration of genetic, non-genetic and environmental ‘cues’. But it is unclear how cue integration is achieved during development, and whether this pattern is general or genotype-specific. 2. In order to test this, we manipulated the maternal and offspring environments of three genetically distinct clones of the water flea Daphnia magna taken from different populations. We then quantified the effect that the genotype, maternal environment and the...

Data from: X-ray micro-CT scanning reveals temporal separation of male harm and female kicking during traumatic mating in seed beetles

Liam R. Dougherty & Leigh W. Simmons
In the seed beetle Callosobruchus maculatus, the male intromittent organ is covered in sharp spines that pierce the female copulatory tract wall during mating. Although the fitness consequences of traumatic mating are well studied in this species, we know much less about how the male and female genitalia interact during mating. This is partly due to the fact that genital interactions occur primarily inside the female, and so are difficult to observe. In this study,...
