Data from: Low second-to-fourth digit ratio predicts indiscriminate social suspicion, not improved trustworthiness detection

Wim De Neys, Astrid Hopfensitz, Jean-François Bonnefon & J.-F. Bonnefon
Testosterone administration appears to make individuals less trusting, and this effect has been interpreted as an adaptive adjustment of social suspicion, that improved the accuracy of trusting decisions. Here, we consider another possibility, namely that testosterone increases the subjective cost of being duped, decreasing the propensity to trust without improving the accuracy of trusting decisions. In line with this hypothesis, we show that second-to-fourth digit ratio (2D : 4D, a proxy for effects of testosterone...

Data from: Allee effects in ants

Gloria M. Luque, Tatiana Giraud & Franck Courchamp
1. Allee effects occur when the aggregation of individuals result in mutually beneficial intraspecific interactions whereby individual fitness, or per capita growth rate, increases with the number of individuals. Allee effects are common in social species due to their cooperative behaviours, such as breeding, feeding, or defence. Allee effects have important implications for many aspects of basic and applied ecology. Over the past decades, the study of Allee effects has influenced population dynamics, community ecology,...

Data from: Two colonisation stages generate two different patterns of genetic diversity within native and invasive ranges of Ulex europaeus

Benjamin Hornoy, Anne Atlan, Valérie Roussel, Yvonne M. Buckley & Michèle Tarayre
Genetic diversity and the way a species is introduced influence the capacity of populations of invasive species to persist in, and adapt to, their new environment. The diversity of introduced populations affects their evolutionary potential, which is particularly important for species that have invaded a wide range of habitats and climates, such as European gorse, Ulex europaeus. This species originated in the Iberian peninsula and colonised Europe in the Neolithic; over the course of the...

Data from: To breed or not to breed: endocrine response to mercury contamination by an Arctic seabird

Sabrina Tartu, Aurélie Goutte, Paco Bustamante, Frédéric Angelier, Børge Moe, Céline Clément-Chastel, Claus Bech, Geir Wing Gabrielsen, Jan Ove Bustnes & Olivier Chastel
Mercury, a ubiquitous toxic element, is known to alter expression of sex steroids and to impair reproduction across vertebrates but the mechanisms underlying these effects are not clearly identified. We examined whether contamination by mercury predicts the probability to skip reproduction in black-legged kittiwakes (Rissa tridactyla) from Svalbard. We also manipulated the endocrine system to investigate the mechanism underlying this relationship. During the pre-laying period, we injected exogenous GnRH (gonadotropin-releasing hormone) to test the ability...

Data from: Evolutionary history and genetic parallelism affect correlated responses to evolution

Mickael Le Gac, Tim F. Cooper, Stéphane Cruveiller, Claudine Médigue & Dominique Schneider
We investigated the relationship between genomic and phenotypic evolution among replicate populations of Escherichia coli evolved for 1000 generations in four different environments. By re-sequencing evolved genomes, we identified parallel changes in genes encoding transcription regulators within and between environments. Depending on both the environment and the altered gene, genetic parallelism at the gene level involved mutations that either repeatedly affected identical codons or domains or were more widely distributed within the relevant genes. Evolved...

Data from: Host resistance, population structure and the long-term persistence of bubonic plague: contributions of a modelling approach in the Malagasy focus

Fanny Gascuel, Marc Choisy, Jean-Marc Duplantier, Florence Débarre & Carine Brouat
Although bubonic plague is an endemic zoonosis in many countries around the world, the factors responsible for the persistence of this highly virulent disease remain poorly known. Classically, the endemic persistence of plague is suspected to be due to the coexistence of plague resistant and plague susceptible rodents in natural foci, and/or to a metapopulation structure of reservoirs. Here, we test separately the effect of each of these factors on the long-term persistence of plague....

Data from: A DNA metabarcoding study of a primate dietary diversity and plasticity across its entire fragmented range

Erwan Quéméré, Fabrice Hibert, Christian Miquel, Emeine Lhuillier, Emmanuel Rasolondraibe, Julie Champeau, Clément Rabarivola, Louis Nusbaumer, Cyrille Chatelain, Laurent Gautier, Patrick Ranirison, Brigitte Crouau-Roy, Pierre Taberlet, Lounès Chikhi & Emeline Lhuillier
In tropical regions, most primary ecosystems have been replaced by mosaic landscapes in which species must cope with a large shift in the distribution of their habitat and associated food resources. Primates are particularly vulnerable to habitat modifications. Most species persist in small fragments surrounded by complex human-mediated matrices whose structure and connectivity may strongly influence their dispersal and feeding behavior. Behavioral plasticity appears to be a crucial parameter governing the ability of organisms to...

Data from: Investigation of the geographic scale of adaptive phenological variation and its underlying genetics in Arabidopsis thaliana

Benjamin Brachi, Romain Villoutreix, Nathalie Faure, Nina-Coralie Hautekèete, Yves Piquot, Maxime Pauwels, Dominique Roby, Joel Cuguen, Joy Bergelson & Fabrice Roux
Despite the increasing number of genomic tools, identifying the genetics underlying adaptive complex traits remains challenging in the model species Arabidopsis thaliana. This is due, at least in part, to the lack of data on the geographical scale of adaptive phenotypic variation. The aims of this study were (i) to tease apart the historical roles of adaptive and nonselective processes in shaping phenological variation in A. thaliana in France and (ii) to gain insights into...

Data from: Surviving in mountain climate refugia: new insights from the genetic diversity and structure of the relict shrub Myrtus nivellei (Myrtaceae) in the Sahara desert

Jérémy Migliore, Alex Baumel, Marianick Juin, Bruno Fady, Anne Roig, Nathalie Duong & Frédéric Médail
The identification of past glacial refugia has become a key topic for conservation under environmental change, since they contribute importantly to shaping current patterns of biodiversity. However, little attention has been paid so far to interglacial refugia despite their key role for the survival of relict species currently occurring in climate refugia. Here, we focus on the genetic consequences of range contraction on the relict populations of the evergreen shrub Myrtus nivellei, endemic in the...

Data from: Estimation of the dispersal of a major pest of maize by cline analysis of a temporary contact zone between two invasive outbreaks

Gérald Bermond, Aurélie Blin, Elodie Vercken, Virginie Ravigné, Adrien Rieux, Sophie Mallez, Thibaut Morel-Journel, Thomas Guilllemaud & Thomas Guillemaud
Dispersal is a key factor in invasion, and in the persistence and evolution of species. Despite the importance of estimates of dispersal distance, dispersal measurement remains a real methodological challenge. In this study, we characterized dispersal by exploiting a specific case of biological invasion, in which multiple introductions in disconnected areas lead to secondary contact between two differentiated expanding outbreaks. By applying cline theory to this ecological setting, we estimated σ, the standard deviation of...

Data from: Migration and stress during reproduction govern telomere dynamics in a seabird

Jannik Schultner, Børge Moe, Olivier Chastel, Claus Bech & Alexander S. Kitaysky
Changes in telomere length are believed to reflect changes in physiological state and life expectancy in animals. However, much remains unknown about the determinants of telomere dynamics in wild populations, and specifically the influence of conditions during highly mobile life-history stages, for example migration. We tested whether telomere dynamics were associated with migratory behaviour and/or with stress during reproduction in free-living seabirds. We induced short-term stress during reproduction in chick-rearing, black-legged kittiwakes (Rissa tridactyla), tracked...

Data from: Sexual selection against natural hybrids may contribute to reinforcement in a house mouse hybrid zone

Yasmin Latour, Guila Ganem, Carole M. Smadja, Pierre Boursot, Pierre Caminade & Marco Perriat-Sanguinet
Sexual selection may hinder gene flow across contact zones when hybrid recognition signals are discriminated against. We tested this hypothesis in a unimodal hybrid zone between Mus musculus musculus and Mus musculus domesticus where a pattern of reinforcement was described and lower hybrid fitness documented. We presented mice from the border of the hybrid zone with a choice between opposite sex urine from the same subspecies versus hybrids sampled in different locations across the zone....

Data from: Species delimitation and phylogeny in the genus Nasutitermes (Termitidae: Nasutitermitinae) in French Guiana

Virginie Roy, Reginaldo Constantino, Vincent Chassany, Stephanie Giusti-Miller, Michel Diouf, Philippe Mora & Myriam Harry
Species delimitation and identification can be arduous for taxa whose morphologic characters are easily confused, which can hamper global biodiversity assessments and pest species management. Exploratory methods of species delimitation that use DNA sequence as their primary information source to establish group membership and estimate putative species boundaries are useful approaches, complementary to traditional taxonomy. Termites of the genus Nasutitermes make interesting models for the application of such methods. They are dominant in Neotropical primary...

Data from: Genetic diversity, clonality and connectivity in the scleractinian coral Pocillopora damicornis: a multi-scale analysis in an insular, fragmented reef system

Mehdi Adjeroud, Aurélie Guérécheau, Jeremie Vidal-Dupiol, Jean-François Flot, Sophie Arnaud-Haond & François Bonhomme
Clonality and genetic structure of the coral Pocillopora damicornis sensu lato were assessed using five microsatellites in 12 populations from four islands of the Society Archipelago (French Polynesia) sampled in June 2008. The 427 analysed specimens fell into 132 multilocus genotypes (MLGs), suggesting that asexual reproduction plays an important role in the maintenance of these populations. A haploweb analysis of ITS2 sequences of each MLG was consistent with all of them being conspecific. Genetic differentiation...

Data from: Multiple aspects of plasticity in clutch size vary among populations of a globally distributed songbird

David F. Westneat, Veronika Bókony, Terry Burke, Olivier Chastel, Henrik Jensen, Thomas Kvalnes, Ádám Z. Lendvai, András Liker, Douglas Mock, Julia Schroeder, P. L. Schwagmeyer, Gabriele Sorci & Ian R. K. Stewart
1. Plasticity in life-history characteristics can influence many ecological and evolutionary phenomena, including how invading organisms cope with novel conditions in new locations or how environmental change affects organisms in native locations. Variation in reaction norm attributes is a critical element to understanding plasticity in life history, yet we know relatively little about the ways in which reaction norms vary within and among populations. 2. We amassed data on clutch size from marked females in...

Data from: Applicability of RAD-tag genotyping for inter-familial comparisons: empirical data from two cetaceans

Amélia Viricel, Eric Pante, Willy Dabin & Benoît Simon-Bouhet
Restriction site-Associated DNA tag (RAD-tag) sequencing has become a popular approach to generate thousands of SNPs used to address diverse questions in population genomics. Comparatively, the suitability of RAD-tag genotyping to address evolutionary questions across divergent species has been the subject of only a few recent studies. Here, we evaluate the applicability of this approach to conduct genome-wide scans for polymorphisms across two cetacean species belonging to distinct families: the short-beaked common dolphin (Delphinus delphis;...

Data from: Cryptic differences in colour among Müllerian mimics: how can the visual capacities of predators and prey shape the evolution of wing colours?

Violaine Llaurens, Mathieu Joron & Marc Théry
Antagonistic interactions between predators and prey often lead to co-evolution. In the case of toxic prey, aposematic colours act as warning signals for predators and play a protective role. Evolutionary convergence in colour patterns among toxic prey evolves due to positive density-dependent selection and the benefits of mutual resemblance in spreading the mortality cost of educating predators over a larger prey assemblage. Comimetic species evolve highly similar colour patterns, but such convergence may interfere with...

Data from: Wolbachia increases susceptibility to Plasmodium infection in a natural system

Flore Zélé, Antoine Nicot, Arnaud Berthomieu, Mylène Weill, Olivier Duron, Ana Rivero & F. Zele
Current views about the impact of Wolbachia on Plasmodium infections are almost entirely based on data regarding artificially transfected mosquitoes. This work has shown that Wolbachia reduces the intensity of Plasmodium infections in mosquitoes, raising the exciting possibility of using Wolbachia to control or limit the spread of malaria. Whether natural Wolbachia infections have the same parasite-inhibiting properties is not yet clear. Wolbachia–mosquito combinations with a long evolutionary history are, however, key for understanding what...

Data from: Frugivores and cheap fruits make fruiting fruitful

Francisco Encinas-Viso, Tomas A. Revilla, Ellen Van Velzen & Rampal S. Etienne
Animal seed dispersal provides an important ecosystem service by strongly benefiting plant communities. There are several theoretical studies on the ecology of plant-animal seed-disperser interactions, but few studies have explored the evolution of this mutualism. Moreover, these studies ignore plant life-history and frugivore foraging behavior. Thus, it remains an open question what the conditions for the diversification of fruit traits are, in spite of the multitude of empirical studies on fruit trait diversity. Here we...

Data from: Wing shape variation associated with mimicry in butterflies

Robert Tyrrell Jones, Yann Le Poul, Annabel C. Whibley, Claire Mérot, Richard H. Ffrench-Constant & Mathieu Joron
Mimetic resemblance in unpalatable butterflies has been studied by evolutionary biologists for over a century, but has largely focused on the convergence in wing color patterns. In Heliconius numata, discrete color-pattern morphs closely resemble co-mimics in the distantly-related genus Melinaea. We examine the possibility that the shape of the butterfly wing also shows adaptive convergence. First, simple measures of forewing dimensions were taken of individuals in a cross between H. numata morphs, and showed quantitative...

Data from: Crop-to-wild gene flow and spatial genetic structure in the closest wild relatives of the cultivated apple

Amandine Cornille, Pierre Gladieux & Tatiana Giraud
Crop-to-wild gene flow have important evolutionary and ecological consequences and require careful consideration in conservation programs for wild genetic resources of potential use in breeding programs and in assessments of the risk of transgene escape into natural ecosystems. Using 26 microsatellites and a set of 1181 trees, we investigated the extent of introgression from the cultivated apple, Malus domestica, to its three closest wild relatives, M. sylvestris in Europe, M. orientalis in the Caucasus and...

Data from: Phylogenetic affiliation of SSU rRNA genes generated by massively parallel sequencing: new insights into the freshwater protist diversity

Najwa Taib, Jean-François Mangot, Isabelle Domaizon, Gisèle Bronner & Didier Debroas
Recent advances in next-generation sequencing (NGS) technologies spur progress in determining the microbial diversity in various ecosystems by highlighting, for example, the rare biosphere. Currently, high-throughput pyrotag sequencing of PCR-amplified SSU rRNA gene regions is mainly used to characterize bacterial and archaeal communities, and rarely to characterize protist communities. In addition, although taxonomic assessment through phylogeny is considered as the most robust approach, similarity and probabilistic approaches remain the most commonly used for taxonomic affiliation....

Data from: Phenotypic and genotypic convergences are influenced by historical contingency and environment in yeast

Aymé Spor, Daniel J. Kvitek, Thibault Nidelet, Juliette Martin, Judith Legrand, Christine Dillmann, Aurélie Bourgais, Dominique De Vienne, Gavin Sherlock & Delphine Sicard
Different organisms have independently and recurrently evolved similar phenotypic traits at different points throughout history. This phenotypic convergence may be caused by genotypic convergence and in addition, constrained by historical contingency. To investigate how convergence may be driven by selection in a particular environment and constrained by history, we analyzed nine life-history traits and four metabolic traits during an experimental evolution of six yeast strains in four different environments. In each of the environments, the...

Data from: Efficient exploration of the space of reconciled gene trees

Gergely J. Szöllősi, Wojciech Rosikiewicz, Bastien Boussau, Eric Tannier & Vincent Daubin
Gene trees record the combination of gene-level events, such as duplication, transfer and loss, and species-level events, such as speciation and extinction. Gene tree-species tree reconciliation methods model these processes by drawing gene trees into the species tree using a series of gene and species level events. The reconstruction of gene trees based on sequence alone almost always involves choosing between statistically equivalent or weakly distinguishable relationships that could be much better resolved based on...

Data from: Phylogenetic inference using discrete characters: performance of ordered and unordered parsimony and of three-item statements

Anaïs Grand, Lina Maria Duque Velez, Adèle Corvez & Michel Laurin
The cladistic literature does not always specify the kind of multistate character treatment that is applied for an analysis. Characters can be treated either as unordered transformation series or as rooted [three-item analysis (3ia)] or unrooted state trees (ordered characters). We aimed to measure the impact of these character treatments on phylogenetic inference. Discrete characters can be represented either as rows or columns in matrices (e.g. for parsimony) or as hierarchies for 3ia. In the...
