Data from: MHC class II assortative mate choice in European badgers (Meles meles)

Yung Wa Sin, Geetha Annavi, Chris Newman, Christina Buesching, Terry Burke, David W. Macdonald & Hannah L. Dugdale
The major histocompatibility complex (MHC) plays a crucial role in the immune system, and in some species, it is a target by which individuals choose mates to optimize the fitness of their offspring, potentially mediated by olfactory cues. Under the genetic compatibility hypothesis, individuals are predicted to choose mates with compatible MHC alleles, to increase the fitness of their offspring. Studies of MHC-based mate choice in wild mammals are under-represented currently, and few investigate more...

Data from: A microsatellite-based linkage map for song sparrows (Melospiza melodia)

Pirmin Nietlisbach, Glauco Camenisch, Thomas Bucher, Jon Slate, Lukas F. Keller & Erik Postma
Although linkage maps are important tools in evolutionary biology, their availability for wild populations is limited. The population of song sparrows (Melospiza melodia) on Mandarte Island, Canada, is among the more intensively studied wild animal populations. Its long-term pedigree data, together with extensive genetic sampling, have allowed the study of a range of questions in evolutionary biology and ecology. However, the availability of genetic markers has been limited. We here describe 191 new microsatellite loci,...

Data from: The evolutionary legacy of size-selective harvesting extends from genes to populations

Silva Uusi-Heikkilä, Andrew R. Whiteley, Anna Kuparinen, Shuichi Matsumura, Paul A. Venturelli, Christian Wolter, Jon Slate, Craig R. Primmer, Thomas Meinelt, Shaun S. Killen, David Bierbach, Giovanni Polverino, Arne Ludwig & Robert Arlinghaus
Size-selective harvesting is assumed to alter life histories of exploited fish populations, thereby negatively affecting population productivity, recovery, and yield. However, demonstrating that fisheries-induced phenotypic changes in the wild are at least partly genetically determined has proved notoriously difficult. Moreover, the population-level consequences of fisheries-induced evolution are still being controversially discussed. Using an experimental approach, we found that five generations of size-selective harvesting altered the life histories and behavior, but not the metabolic rate, of...

Data from: The evolution of novel host use is unlikely to be constrained by tradeoffs or a lack of genetic variation

Zachariah Gompert, Joshua P. Jahner, Cynthia F. Scholl, Joseph S. Wilson, Lauren K. Lucas, Victor Soria-Carrasco, James A. Fordyce, Chris C. Nice, C. Alex Buerkle & Matthew L. Forister
The genetic and ecological factors that shape the evolution of animal diets remain poorly understood. For herbivorous insects, the expectation has been that trade-offs exist, such that adaptation to one host plant reduces performance on other potential hosts. We investigated the genetic architecture of alternative host use by rearing individual Lycaeides melissa butterflies from two wild populations in a crossed design on two hosts (one native and one introduced) and analysing the genetic basis of...

Data from: Troubleshooting the potential pitfalls of cross-fostering

Isabel S. Winney, Shinichi Nakagawa, Yu-Hsun Hsu, Terry Burke, Julia Schroeder & Isabel Winney
1. Cross-fostering is the transfer of offspring between their natal environment and a new social environment. This method allows researchers to disentangle the genetic and interacting environmental effects that influence phenotypes, and is popular in both wild and laboratory studies. Here, we discuss three factors that might bias cross-fostering and influence ecological and evolutionary conclusions if not accommodated. 2. First, cross-fostering tends to be spatially and temporally non-random because heterogeneous breeding conditions can result in...

Data from: Experimental evidence for phonemic contrasts in a nonhuman vocal system

Sabrina Engesser, Jodie M. S. Crane, James L. Savage, Andrew F. Russell & Simon W. Townsend
The ability to generate new meaning by rearranging combinations of meaningless sounds is a fundamental component of language. Although animal vocalizations often comprise combinations of meaningless acoustic elements, evidence that rearranging such combinations generates functionally distinct meaning is lacking. Here, we provide evidence for this basic ability in calls of the chestnut-crowned babbler (Pomatostomus ruficeps), a highly cooperative bird of the Australian arid zone. Using acoustic analyses, natural observations, and a series of controlled playback...

Data from: Range expansion and retraction along a moving contact zone has no effect on the genetic diversity of two passerine birds

Jan O. Engler, Jean Secondi, Deborah A. Dawson, Ortwin Elle & Axel Hochkirch
Disentangling the factors shaping species distributions remains a central goal in biogeography, ecology and evolutionary biology. The extrinsic pressures that may facilitate range shifts, such as climatic factors or biotic interactions are well known. However, in contrast, the possible intrinsic factors are manifold and hard to generalize across taxa. Recently, several theoretical studies have investigated the consequences of moving range borders on genetic diversity. However, empirical studies that support or refute these theoretical predictions are...

Data from: Distinguishing between determinate and indeterminate growth in a long-lived mammal

Hannah S. Mumby, Simon N. Chapman, Jennie A. H. Crawley, Khyne U. Mar, Win Htut, Aung Thura Soe, Htoo Htoo Aung & Virpi Lummaa
Background: The growth strategy of a species influences many key aspects of its life-history. Animals can either grow indeterminately (throughout life), or grow determinately, ceasing at maturity. In mammals, continued weight gain after maturity is clearly distinguishable from continued skeletal growth (indeterminate growth). Elephants represent an interesting candidate for studying growth because of their large size, long life and sexual dimorphism. Objective measures of their weight, height and age, however, are rare. Results: We investigate...

Data from: Low but contrasting neutral genetic differentiation shaped by winter temperature in European great tits

Mélissa Lemoine, Kay Lucek, Charles Perrier, Verena Saladin, Frank Adriaensen, Emilio Barba, Eduardo J. Belda, Anne Charmantier, Mariusz Cichon, Eeva Tapio, Arnaud Gregoire, Camilla A. Hinde, Arild Johnsen, Jan Komdeur, Raivo Mand, Erik Matthysen, Ana Claudia Norte, Natalia Pitala, Ben C. Sheldon, Tore Slagsvold, Joost M. Tinbergen, Janos Torok, Richard Ubels, Kees Van Oers, Marcel E. Visser … & Tapio Eeva
Gene flow is usually thought to reduce genetic divergence and impede local adaptation by homogenising gene pools between populations. However, evidence for local adaptation and phenotypic differentiation in highly mobile species, experiencing high levels of gene flow, is emerging. Assessing population genetic structure at different spatial scales is thus a crucial step towards understanding mechanisms underlying intraspecific differentiation and diversification. Here, we studied the population genetic structure of a highly mobile species – the great...

Root and leaf phenology of Scandinavian subarctic plant communities, 2008-2009

V.L Sloan, B.J Fletcher & G.K Phoenix
This dataset consists of measurements of leaf and root growth, species abundance and soil temperature made in ten subarctic plant communities located at the Arctic Biosphere Atmosphere Coupling at Multiple Scales (ABACUS) project sites near to Abisko, Sweden, and Kevo, Finland. The data were collected during the summer growing seasons (May to September) in 2008 and 2009, and comprise field survey measurements, temperature logs and values derived from analyses of mini-rhizotron images.

Data from: Disruptive viability selection on a black plumage trait associated with dominance

Paul Acker, Arnaud Grégoire, Margaux Rat, Claire N. Spottiswoode, René E. Van Dijk, Matthieu Paquet, Jennifer C. Kaden, Roger Pradel, Ben J. Hatchwell, Rita Covas & Claire Doutrelant
Traits used in communication, such as colour signals, are expected to have positive consequences for reproductive success, but their associations with survival are little understood. Previous studies have mainly investigated linear relationships between signals and survival, but both hump-shaped and U-shaped relationships can also be predicted, depending on the main costs involved in trait expression. Furthermore, few studies have taken the plasticity of signals into account in viability selection analyses. The relationship between signal expression...

Data from: The genetic architecture of sexually selected traits in two natural populations of Drosophila montana

Paris Veltsos, Emma Gregson, Barbara Morrissey, Jon Slate, Anneli Hoikkala, Roger K. Butlin & Michael G. Ritchie
We investigated the genetic architecture of courtship song and cuticular hydrocarbon traits in two phygenetically distinct populations of Drosophila montana. In order to study natural variation in these two important traits, we analysed within-population crosses among individuals sampled from the wild. Hence, the genetic variation analysed should represent that available for natural and sexual selection to act upon. In contrast to previous between-population crosses in this species, no major QTLs were detected, perhaps because the...

Data from: The alignment between phenotypic plasticity, the major axis of genetic variation and the response to selection

Martin I. Lind, Kylie Yarlett, Julia Reger, Mauricio J. Carter & Andrew P. Beckerman
Phenotypic plasticity is the ability of a genotype to produce more than one phenotype in order to match the environment. Recent theory proposes that the major axis of genetic variation in a phenotypically plastic population can align with the direction of selection. Therefore, theory predicts that plasticity directly aids adaptation by increasing genetic variation in the direction favoured by selection and reflected in plasticity. We evaluated this theory in the freshwater crustacean Daphnia pulex, facing...

Data from: Linkage mapping of a polymorphic plumage locus associated with intermorph incompatibility in the Gouldian finch (Erythrura gouldiae)

Kang-Wook Kim, Simon C. Griffith & Terry Burke
Colour polymorphism is known to facilitate speciation but the genetic basis of animal pigmentation and how colour polymorphisms contribute to speciation is poorly understood. Restricted recombination may promote linkage disequilibrium between the colour locus and incompatibility genes. Genomic rearrangement and the position of relevant loci within a chromosome are important factors that influence the frequency of recombination. Therefore, it is important to know the position of the colour locus, gene order and recombination landscape of...

Data from: No evidence for MHC class I based disassortative mating in a wild population of great tits

Irem Sepil, Reinder Radersma, Anna W. Santure, Isabelle De Cauwer, Jon Slate & Ben C. Sheldon
Genes of the major histocompatibility complex (MHC) are regarded as a potentially important target of mate choice due to the fitness benefits that may be conferred to the offspring. According to the complementary genes hypothesis, females mate with MHC dissimilar males to enhance the immunocompetence of their offspring or to avoid inbreeding depression. Here, we investigate whether selection favours a preference for maximally dissimilar or optimally dissimilar MHC class I types, based on MHC genotypes,...

Data from: Sources of variability in cytosolic calcium transients triggered by stimulation of homogeneous uro-epithelial cell monolayers

Peter A. Appelby, Saqib Shabir, Jennifer Southgate & Dawn Walker
Epithelial tissue structure is the emergent outcome of the interactions between large numbers of individual cells. Experimental cell biology offers an important tool to unravel these complex interactions, but current methods of analysis tend to be limited to mean field approaches or representation by selected subsets of cells. This may result in bias towards cells that respond in a particular way and/or neglect local, context-specific cell responses. Here, an automated algorithm was applied to examine...

Data from: Genetic pollution of a threatened native crested newt species through hybridization with an invasive congener in the Netherlands

Willem R. M. Meilink, Jan W. Arntzen, Jeroen J. C. W. Van Delft & Ben Wielstra
Genetic pollution of a native species through hybridization with an invasive species poses an insidious conservation threat. To expose genetic pollution, molecular methods employing multilocus data are required. We present a case study of genetic pollution via hybridization of a native crested newt species, Triturus cristatus, by the invasive T. carnifex on the Veluwe in the Netherlands. We sequenced 50 nuclear markers by next generation sequencing and one mitochondrial marker by Sanger sequencing for four...

Data from: Comparison of Nottingham Prognostic Index and Adjuvant Online prognostic tools in young women with breast cancer: review of a single-institution experience

Benjamin Joseph Hearne, M. Dawn Teare, Mohammad Butt & Leslie Donaldson
Objective: Accurately predicting the prognosis of young patients with breast cancer (<40 years) is uncertain since the literature suggests they have a higher mortality and that age is an independent risk factor. In this cohort study we considered two prognostic tools; Nottingham Prognostic Index and Adjuvant Online (Adjuvant!), in a group of young patients, comparing their predicted prognosis with their actual survival. Setting: North East England. Participants: Data was prospectively collected from the breast unit...

Data from: Sex differences in parental care: gametic investment, sexual selection and social environment

András Liker, Robert P. Freckleton, Vladimir Remes & Tamás Székely
Male and female parents often provide different type and amount of care to their offspring. Three major drivers have been proposed to explain parental sex roles: (i) differential gametic investment by males and females that precipitates into sex difference in care, (ii) different intensity of sexual selection acting on males and females, and (iii) biased social environment that facilitates the more common sex to provide more care. Here we provide the most comprehensive assessment of...

Data from: Shared and non-shared genomic divergence in parallel ecotypes of Littorina saxatilis at a local scale

Mark Ravinet, Anja Westram, Kerstin Johannesson, Roger Butlin, Carl André & Marina Panova
Parallel speciation occurs when selection drives repeated, independent adaptive divergence that reduces gene flow between ecotypes. Classical examples show parallel speciation originating from shared genomic variation, but this does not seem to be the case in the rough periwinkle (Littorina saxatilis) that has evolved considerable phenotypic diversity across Europe, including several distinct ecotypes. Small ‘wave’ ecotype snails inhabit exposed rocks and experience strong wave action, while thick-shelled, ‘crab’ ecotype snails are larger and experience crab...

Data from: Opportunities and challenges of Integral Projection Models for modeling host-parasite dynamics

C. Jessica E. Metcalf, Andrea L. Graham, Micaela Martinez-Bakker & Dylan Z. Childs
Epidemiological dynamics are shaped by and may in turn shape host demography. These feedbacks can result in hard to predict patterns of disease incidence. Mathematical models that integrate infection and demography are consequently a key tool for informing expectations for disease burden and identifying effective measures for control. A major challenge is capturing the details of infection within individuals and quantifying their downstream impacts to understand population-scale outcomes. For example, parasite loads and antibody titres...

Data from: Exact Bayesian inference for animal movement in continuous time

Paul G. Blackwell, Mu Niu, Mark S. Lambert & Scott D. LaPoint
It is natural to regard most animal movement as a continuous-time process, generally observed at discrete times. Most existing statistical methods for movement data ignore this; the remainder mostly use discrete-time approximations, the statistical properties of which have not been widely studied, or are limited to special cases. We aim to facilitate wider use of continuous-time modelling for realistic problems. We develop novel methodology which allows exact Bayesian statistical analysis for a rich class of...

Data from: Middle Jurassic vegetation dynamics based on quantitative analysis of spore/pollen assemblages from the Ravenscar Group, North Yorkshire, UK

Sam M. Slater & Charles H. Wellman
Quantitative analysis of the distribution of dispersed spores and pollen (sporomorphs) has been used to assess temporal floral variation through the Middle Jurassic Ravenscar Group (Aalenian–Bathonian), North Yorkshire, UK. Aalenian, Bajocian and Bathonian strata possess relatively distinct sporomorph and palynofacies assemblages, which potentially reflect a dynamic history regarding the nature of parent vegetation. Specifically, Aalenian palynofloras are composed of a heterogeneous mixture of conifers, ferns, simple monosulcate pollen producers, sphenophytes and Caytoniales; Bajocian palynofloras are...

Data from: Evolutionary novelty in a butterfly wing pattern through enhancer shuffling

Richard W. R. Wallbank, Simon W. Baxter, Carolina Pardo-Diaz, Joseph J. Hanly, Simon H. Martin, James Mallet, Kanchon K. Dasmahapatra, Camilo Salazar, Mathieu Joron, Nicola Nadeau, W. Owen McMillan & Chris D. Jiggins
An important goal in evolutionary biology is to understand the genetic changes underlying novel morphological structures. We investigated the origins of a complex wing pattern found among Amazonian Heliconius butterflies. Genome sequence data from 142 individuals across 17 species identified narrow regions associated with two distinct red colour pattern elements, dennis and ray. We hypothesise that these modules in non-coding sequence represent distinct cis-regulatory loci that control expression of the transcription factor optix, which in...

Data from: Replicated analysis of the genetic architecture of quantitative traits in two wild great tit populations

Anna W. Santure, Jocelyn Poissant, Isabelle De Cauwer, Kees Van Oers, Matthew R. Robinson, John L. Quinn, Martien A. M. Groenen, Marcel E. Visser, Ben C. Sheldon & Jon Slate
Currently there is much debate on the genetic architecture of quantitative traits in wild populations. Is trait variation influenced by many genes of small effect or by a few genes of major effect? Where is additive genetic variation located in the genome? Do the same loci cause similar phenotypic variation in different populations? Great tits (Parus major) have been studied extensively in long-term studies across Europe, and consequently are considered an ecological 'model organism'. Recently,...
