Data from: Fitness costs in spatially structured environments

Florence Débarre
The clustering of individuals that results from limited dispersal is a double-edged sword: while it allows for local interactions to be mostly among related individuals, it also results in increased local competition. Here I show that, because they mitigate local competition, fitness costs such as reduced fecundity or reduced survival are less costly in spatially structured environments than in non spatial settings. I first present a simple demographic example to illustrate how spatial structure weakens...

Data from: Population genetic structure of serotine bats (Eptesicus serotinus) across Europe and implications for the potential spread of bat rabies (European bat lyssavirus EBLV-1)

Caroline Moussy, Helen Atterby, Amber G. F. Griffiths, Theodore R. Allnut, Fiona Mathews, Graham C. Smith, James N. Aegerter, Stuart Bearhop & David J. Hosken
Understanding of the movements of species at multiple scales is essential to appreciate patterns of population connectivity and in some cases, the potential for pathogen transmission. The serotine bat (Eptesicus serotinus) is a common and widely distributed species in Europe where it frequently harbours European bat lyssavirus type 1 (EBLV-1), a virus causing rabies and transmissible to humans. In the United Kingdom, it is rare, with a distribution restricted to south of the country and...

Data from: Temporal dynamics of linkage disequilibrium in two populations of bighorn sheep

Joshua M. Miller, Jocelyn Poissant, René M. Malenfant, John T. Hogg & David W. Coltman
Linkage disequilibrium (LD) is the nonrandom association of alleles at two markers. Patterns of LD have biological implications as well as practical ones when designing association studies or conservation programs aimed at identifying the genetic basis of fitness differences within and among populations. However, the temporal dynamics of LD in wild populations has received little empirical attention. In this study, we examined the overall extent of LD, the effect of sample size on the accuracy...

Data from: Assessing bundles of ecosystem services from regional to landscape scale: insights from the French Alps

Emilie Crouzat, Maud Mouchet, Francis Turkelboom, Coline Byczek, Jeroen Meersmans, Frederic Berger, Pieter Johannes Verkerk & Sandra Lavorel
1. Assessments of ecosystem services (ES) and biodiversity (hereafter ecological parameters) provide a comprehensive view of the links between landscapes, ecosystem functioning and human well-being. The investigation of consistent associations between ecological parameters, called bundles, and of their links to landscape composition and structure is essential to inform management and policy, yet it is still in its infancy. 2. We mapped over the French Alps an unprecedented array of 18 ecological parameters (16 ES and...

Data from: Diet complexity in early life affects survival in released pheasants by altering foraging efficiency, food choice, handling skills and gut morphology

Mark A. Whiteside, Rufus Sage & Joah R. Madden
1. Behavioural and physiological deficiencies are major reasons why reintroduction programmes suffer from high mortality when captive animals are used. Mitigation of these deficiencies is essential for successful reintroduction programmes. 2. Our study manipulated early developmental diet to better replicate foraging behaviour in the wild. Over 2 years, we hand-reared 1800 pheasants (Phasianus colchicus), from 1 day old, for 7 weeks under different dietary conditions. In year one, 900 pheasants were divided into three groups...

Data from: Anthropogenic and ecological drivers of amphibian disease (Ranavirosis)

Alexandra C. North, David J. Hodgson, Stephen J. Price & Amber G. F. Griffiths
Ranaviruses are causing mass amphibian die-offs in North America, Europe and Asia, and have been implicated in the decline of common frog (Rana temporaria) populations in the UK. Despite this, we have very little understanding of the environmental drivers of disease occurrence and prevalence. Using a long term (1992-2000) dataset of public reports of amphibian mortalities, we assess a set of potential predictors of the occurrence and prevalence of Ranavirus-consistent common frog mortality events in...

Data from: Phenotype-environment matching in sand fleas

Martin Stevens, Annette C. Broderick, Brendan J. Godley, Alice E. Lown, Jolyon Troscianko, Nicola Weber & Sam B. Weber
Camouflage is perhaps the most widespread anti-predator strategy in nature, found in numerous animal groups. A long-standing prediction is that individuals should have camouflage tuned to the visual backgrounds where they live. However, while several studies have demonstrated phenotype–environment associations, few have directly shown that this confers an improvement in camouflage, particularly with respect to predator vision. Here, we show that an intertidal crustacean, the sand flea (Hippa testudinaria), has coloration tuned to the different...

Data from: How integrated are behavioural and endocrine stress response traits? A repeated measures approach to testing the stress coping style model

Kay Boulton, Elsa Couto, Andrew J. Grimmer, Ryan L. Earley, Adelino V.M. Canario, Alastair J. Wilson, Craig A. Walling & Adelino V. M. Canario
It is widely expected that physiological and behavioral stress responses will be integrated within divergent stress-coping styles (SCS) and that these may represent opposite ends of a continuously varying reactive–proactive axis. If such a model is valid, then stress response traits should be repeatable and physiological and behavioral responses should also change in an integrated manner along a major axis of among-individual variation. While there is some evidence of association between endocrine and behavioral stress...

Data from: Siderophore cooperation of the bacterium Pseudomonas fluorescens in soil

Adela M. Luján, Pedro Gómez & Angus Buckling
While social interactions play an important role for the evolution of bacterial siderophore production in vitro, the extent to which siderophore production is a social trait in natural populations is less clear. Here, we demonstrate that siderophores act as public goods in a natural physical environment of Pseudomonas fluorescens: soil-based compost. We show that monocultures of siderophore producers grow better than non-producers in soil, but non-producers can exploit others' siderophores, as shown by non-producers' ability...

Data from: An invasive non-native mammal population conserves genetic diversity lost from its native range

Andrew J. Veale, Olivia J. Holland, Robbie A. McDonald, Mick N. Clout, Dianne Gleeson & D.M. Gleeson
Invasive, non-native species are one of the major causes of global biodiversity loss. Although they are, by definition, successful in their non-native range, their populations generally show major reductions in their genetic diversity during the demographic bottleneck they experience during colonization. By investigating the mitochondrial genetic diversity of an invasive non-native species, the stoat Mustela erminea, in New Zealand and comparing it to diversity in the species’ native range in Great Britain, we reveal the...

Data from: Genome-wide transcriptional signatures of migratory flight activity in a globally invasive insect pest

Christopher M. Jones, Alexie Papanicolaou, George K. Mironidis, John Vontas, Yihua Yang, Ka S. Lim, Kumar S. Singh, John G. Oakeshott, Christopher Bass, Jason W. Chapman & Chris Bass
Migration is a key life history strategy for many animals and requires a suite of behavioural, morphological and physiological adaptations which together form the ‘migratory syndrome’. Genetic variation has been demonstrated for many traits that make up this syndrome, but the underlying genes involved remain elusive. Recent studies investigating migration-associated genes have focussed on sampling migratory and nonmigratory populations from different geographic locations but have seldom explored phenotypic variation in a migratory trait. Here, we...

Data from: Sexual selection and population divergence I: the influence of socially flexible cuticular hydrocarbon expression in male field crickets (Teleogryllus oceanicus)

Sonia Pascoal, Magdalena Mendrok, Christopher Mitchell, Alastair J. Wilson, John Hunt & Nathan W. Bailey
Debates about how coevolution of sexual traits and preferences might promote evolutionary diversification have permeated speciation research for over a century. Recent work demonstrates that the expression of such traits can be sensitive to variation in the social environment. Here we examined social flexibility in a sexually selected male trait – cuticular hydrocarbon (CHC) profiles – in the field cricket Teleogryllus oceanicus and tested whether population genetic divergence predicts the extent or direction of social...

Data from: Human mining activity across the ages determines the genetic structure of modern brown trout (Salmo trutta L.) populations

R. Andrew King, Jamie R. Stevens & Josephine R. Paris
Humans have exploited the earth's metal resources for thousands of years leaving behind a legacy of toxic metal contamination and poor water quality. The southwest of England provides a well-defined example, with a rich history of metal mining dating to the Bronze Age. Mine water washout continues to negatively impact water quality across the region where brown trout (Salmo trutta L.) populations exist in both metal-impacted and relatively clean rivers. We used microsatellites to assess...

Data from: Developmental plasticity affects sexual size dimorphism in an anole lizard

Camille Bonneaud, Erin Marnocha, Anthony Herrel, Bieke Vanhooydonck, Duncan J. Irschick & Thomas B. Smith
While developmental plasticity has been shown to contribute to sexual size dimorphism (SSD) in laboratory studies, its role in shaping SSD variation in wild vertebrate populations is unclear. Here we use a field study and a laboratory experiment to show that resource availability influences the degree of SSD among insular populations of Anolis sagrei lizards in the Bahamas. Total amounts of food biomass explained variation in male, but not female, body size on six Bahamian...

Data from: Assembly mechanisms determining high species turnover in aquatic communities over regional and continental scales

Duarte S. Viana, Jordi Figuerola, Klaus Schwenk, Marina Manca, Anders Hobæk, Marit Mjelde, Christopher D. Preston, Richard J. Gornall, Jane M. Croft, Robert A. King, Andy J. Green & Luis Santamaría
Niche and neutral processes drive community assembly and metacommunity dynamics, but their relative importance might vary with the spatial scale. The contribution of niche processes is generally expected to increase with increasing spatial extent at a higher rate than that of neutral processes. However, the extent to what community composition is limited by dispersal (usually considered a neutral process) over increasing spatial scales might depend on the dispersal capacity of composing species. To investigate the...

Data from: Impacts of regular and random noise on the behaviour, growth and development of larval Atlantic cod (Gadus morhua)

Sophie L. Nedelec, Stephen D. Simpson, Erica L. Morley, Brendan Nedelec & Andrew N. Radford
Anthropogenic noise impacts behaviour and physiology in many species, but responses could change with repeat exposures. As repeat exposures can vary in regularity, identifying regimes with less impact is important for regulation. We use a 16-day split-brood experiment to compare effects of regular and random acoustic noise (playbacks of recordings of ships), relative to ambient-noise controls, on behaviour, growth and development of larval Atlantic cod (Gadus morhua). Short-term noise caused startle responses in newly hatched...

Data from: Male burying beetles extend, not reduce, parental care duration when reproductive competition is high

Paul E. Hopwood, Allen J. Moore, Tom Tregenza & Nick J. Royle
Male parents spend less time caring than females in many species with biparental care. The traditional explanation for this pattern is that males have lower confidence of parentage, so they desert earlier in favor of pursuing other mating opportunities. However, one recent alternative hypothesis is that prolonged male parental care might also evolve if staying to care actively improves paternity. If this is the case, an increase in reproductive competition should be associated with increased...

Data from: Direct and indirect effects of nursery habitats on coral-reef fish assemblages, grazing pressure, and benthic dynamics

Alastair R. Harborne, Ivan Nagelkerken, Nicholas H. Wolff, Yves-Marie Bozec, Martijn Dorenbosch, Monique G. G. Grol & Peter J. Mumby
Migrating species are common within seascapes, but the potential for these movements to alter the populations and functional roles of non-migrating species (e.g. by increasing predation) is rarely investigated. This study considers whether the presence of nursery habitats (mangroves and seagrass) simply enhances the abundance of nursery-using parrotfishes and piscivores on nearby coral reefs, or also affects other parrotfishes. Data from 131 reef sites and multiple seascape configurations across 13 degrees of latitude were used...

Data from: Sex differences in senescence: the role of intra-sexual competition in early adulthood

Christopher Beirne, Richard Delahay & Andrew Young
Males and females frequently differ in their rates of ageing, but the origins of these differences are poorly understood. Sex differences in senescence have been hypothesized to arise, because investment in intra-sexual reproductive competition entails costs to somatic maintenance, leaving the sex that experiences stronger reproductive competition showing higher rates of senescence. However, evidence that sex differences in senescence are attributable to downstream effects of the intensity of intra-sexual reproductive competition experienced during the lifetime...

Data from: Do stressful conditions make adaptation difficult? Guppies in the oil-polluted environments of southern Trinidad

Gregor Rolshausen, Dawn A. T. Phillip, Denise M. Beckles, Ali Akbari, Subhasis Ghoshal, Patrick B. Hamilton, Charles R. Tyler, Alan G. Scarlett, Indar Ramnarine, Paul Bentzen & Andrew P. Hendry
The ability of populations to rapidly adapt to new environments will determine their future in an increasingly human-modified world. Although meta-analyses do frequently uncover signatures of local adaptation, they also reveal many exceptions. We suggest that particular constraints on local adaptation might arise when organisms are exposed to novel stressors, such as anthropogenic pollution. To inform this possibility, we studied the extent to which guppies (Poecilia reticulata) show local adaptation to oil pollution in southern...

Data from: The evolution of bacterial resistance against bacteriophages in the horse chestnut phyllosphere is general across both space and time

Britt Koskella & Nicole Parr
Insight to the spatial and temporal scales of coevolution is key to predicting the outcome of host–parasite interactions and spread of disease. For bacteria infecting long-lived hosts, selection to overcome host defences is just one factor shaping the course of evolution; populations will also be competing with other microbial species and will themselves be facing infection by bacteriophage viruses. Here, we examine the temporal and spatial patterns of bacterial adaptation against natural phage populations from...

Data from: Banded mongooses avoid inbreeding when mating with members of the same natal group

Jennifer L. Sanderson, Jinliang Wang, Emma I. K. Vitikainen, Michael A. Cant & Hazel J. Nichols
Inbreeding and inbreeding avoidance are key factors in the evolution of animal societies, influencing dispersal and reproductive strategies which can affect relatedness structure and helping behaviours. In cooperative breeding systems, individuals typically avoid inbreeding through reproductive restraint and/or dispersing to breed outside their natal group. However, where groups contain multiple potential mates of varying relatedness, strategies of kin recognition and mate choice may be favoured. Here, we investigate male mate choice and female control of...

Data from: Macronutrient balance mediates the growth of sexually selected weapons but not genitalia in male broad-horned beetles

Clarissa M. House, Kim Jensen, James Rapkin, Sarah Lane, Kensuke Okada, David J. Hosken & John Hunt
Condition is defined as the pool of resources available to an individual that can be allocated to fitness-enhancing traits. Consequently, condition could influence developmental trade-offs if any occur. Although many studies have manipulated diet to demonstrate condition-dependent trait expression, few studies have determined the contribution of specific nutrients to condition or trade-offs. We used nutritional geometry to quantify the effects of dietary protein and carbohydrate content on larval performance and the development of adult morphology...

Data from: Reef flattening effects on total richness and species responses in the Caribbean

Steven P. Newman, Erik H. Meesters, Charlie S. Dryden, Stacey M. Williams, Cristina Sanchez, Peter J. Mumby, Nicholas V.C. Polunin & Nicholas V. C. Polunin
1. There has been ongoing flattening of Caribbean coral reefs with the loss of habitat having severe implications for these systems. Complexity and its structural components are important to fish species richness and community composition, but little is known about its role for other taxa or species-specific responses. 2. This study reveals the importance of reef habitat complexity and structural components to different taxa of macrofauna, total species richness, and individual coral and fish species...

Data from: Terminal investment in the gustatory appeal of nuptial food gifts in crickets

Kristin R. Duffield, John Hunt, James Rapkin, Ben M. Sadd & Scott K. Sakaluk
Investment in current versus future reproduction represents a prominent trade-off in life-history theory, and is likely dependent on an individual's life expectancy. The terminal investment hypothesis posits that a reduction in residual reproductive value (i.e., potential for future offspring) will result in increased investment in current reproduction. We tested the hypothesis that male decorated crickets (Gryllodes sigillatus), when cued to their impending mortality, should increase their reproductive effort by altering the composition of their nuptial...
