Data from: New resources for genetic studies in Populus nigra: genome wide SNP discovery and development of a 12k Infinium array

P. Faivre Rampant, G. Zaina, V. Jorge, S. Giacomello, V. Segura, S. Scalabrin, V. Guérin, E. De Paoli, C. Aluome, M. Viger, F. Cattonaro, A. Payne, P. PaulStephenRaj, MC. Le Paslier, A. Berard, M. R. Allwright, M. Villar, G. Taylor, C. Bastien, M. Morgante, P. Faivre-Rampant & M. C. Le Paslier
Whole genome resequencing of 51 Populus nigra (L.) individuals from across Western Europe was performed using Illumina platforms. A total number of 1,878,727 SNPs distributed along the P. nigra reference sequence were identified. The SNP calling accuracy was validated with Sanger sequencing. SNPs were selected within 14 previously identified QTL regions; 2916 expressional candidate genes related to rust resistance, wood properties, water-use efficiency and bud phenology and 1732 genes randomly spread across the genome. Over...

Data from: Modeling spatial expansion of invasive alien species: relative contributions of environmental and anthropogenic factors to the spreading of the harlequin ladybird in France

Sophie Veran, Sylvain Piry, Vincent Ternois, Christine N. Meynard, Benoit Facon & Arnaud Estoup
Species distribution models (SDM) have often been used to predict the potential ranges of introduced species and prioritize management strategies. However, this approach assumes equilibrium between occurrences and environmental gradients, an assumption which is violated during the invasion process, where many suitable sites are empty because the species has not yet reached them. Here we considered the invasive ladybird Harmonia axyridis as a case study to show the benefits of using a dynamic colonization–extinction model...

Data from: Varroa destructor changes cuticular hydrocarbons to mimic its new host.

Zachary Y. Huang, Yves Le Conte, Jean-Philippe Christidès, Zhi Jiang Zeng, Maurice Roux, Anne-Genevieve Bagnères, Z. Y. Huang, Y. Le Conte & Z. J. Zeng
Varroa destructor (Vd) is a honeybee ectoparasite. Its original host is the Asian honeybee, Apis cerana, but it has also become a severe, global threat to the European honeybee, Apis mellifera. Previous studies have shown that Varroa can mimic a host's cuticular hydrocarbons (HC), enabling the parasite to escape the hygienic behaviour of the host honeybees. By transferring mites between the two honeybee species, we further demonstrate that Vd is able to mimic the cuticular...

Data from: Globally, functional traits are weak predictors of juvenile tree growth, and we do not know why

C. E. Timothy Paine, Lucy Amissah, Harald Auge, Christopher Baraloto, Martin Baruffol, Nils Bourland, Helge Bruelheide, Kasso Daïnou, Roland C. De Gouvenain, Jean-Louis Doucet, Susan Doust, Paul V. A. Fine, Claire Fortunel, Josephine Haase, Karen D. Holl, Hervé Jactel, Xuefei Li, Kaoru Kitajima, Julia Koricheva, Cristina Martínez-Garza, Christian Messier, Alain Paquette, Christopher Philipson, Daniel Piotto, Lourens Poorter … & Andy Hector
1. Plant functional traits, in particular specific leaf area (SLA), wood density and seed mass, are often good predictors of individual tree growth rates within communities. Individuals and species with high SLA, low wood density and small seeds tend to have faster growth rates. 2. If community-level relationships between traits and growth have general predictive value, then similar relationships should also be observed in analyses that integrate across taxa, biogeographic regions and environments. Such global...

Data from: Single-nucleotide polymorphism discovery and validation in high-density SNP array for genetic analysis in European white oaks

Camille Lepoittevin, Catherine Bodénès, Emilie Chancerel, Laure Villate, Tiange Lang, Isabelle Lesur, Christophe Boury, François Ehrenmann, Diana Zelenika, Anne Boland, Céline Besse, Pauline Garnier-Géré, Christophe Plomion & Antoine Kremer
An Illumina Infinium SNP genotyping array was constructed for European white oaks. Six individuals of Quercus petraea and Q. robur were considered for SNP discovery using both previously obtained Sanger sequences across 676 gene regions (1371 in vitro SNPs) and Roche 454 technology sequences from 5112 contigs (6542 putative in silico SNPs). The 7913 SNPs were genotyped across the six parental individuals, full-sib progenies (one within each species and two interspecific crosses between Q. petraea...

Data from: Impact of past climatic changes and resource availability on the population demography of three food-specialist bees

Simon Dellicour, Denis Michez, Jean-Yves Rasplus & Patrick Mardulyn
Past climate change is known to have strongly impacted current patterns of genetic variation of animals and plants in Europe. However, ecological factors also have the potential to influence demographic history, and thus patterns of genetic variation. In this study, we investigated the impact of past climate, and also the potential impact of host plant species abundance, on intraspecific genetic variation in three co-distributed and related specialized solitary bees of the genus Melitta with very...

Data from: Combining GWAS and RNA-seq approaches for detection of the causal mutation for hereditary junctional epidermolysis bullosa in sheep

Aroa Suárez-Vega, Beatriz Gutiérrez-Gil, Julio Benavides, Valentín Perez, Gwenola Tosser-Klopp, Christophe Klopp, Stephen J. Keennel & Juan José Arranz
In this study, we demonstrate the use of a genome-wide association mapping together with RNA-seq in a reduced number of samples, as an efficient approach to detect the causal mutation for a Mendelian disease. Junctional epidermolysis bullosa is a recessive genodermatosis that manifests with neonatal mechanical fragility of the skin, blistering confined to the lamina lucida of the basement membrane and severe alteration of the hemidesmosomal junctions. In Spanish Churra sheep, junctional epidermolysis bullosa (JEB)...

Data from: Evidence of divergent selection for drought and cold tolerance at landscape and local scales in Abies alba Mill. in the French Mediterranean Alps

Anna M. Roschanski, Katalin Csilléry, Sascha Liepelt, Sylvie Oddou-Muratorio, Birgit Ziegenhagen, Frédéric Huard, Kristian K. Ullrich, Dragos Postolache, Giovanni G. Vendramin & Bruno Fady
Understanding local adaptation in forest trees is currently a key research and societal priority. Geographically and ecologically marginal populations provide ideal case studies, because environmental stress along with reduced gene flow can facilitate the establishment of locally adapted populations. We sampled European silver fir (Abies alba Mill.) trees in the French Mediterranean Alps, along the margin of its distribution range, from pairs of high and low elevation plots on four different mountains situated along a...

Data from: Are generalist Aphidiinae (Hym. Braconidae) mostly cryptic species complexes?

Stéphane A. P. Derocles, Manuel Plantegenest, Jean-Yves Rasplus, Alexia Marie, Darren M. Evans, David H. Lunt & Anne Le Ralec
Aphidiinae are mostly composed of specialist parasitoids and the few species described as generalist are suspected to be composed of cryptic specialists, almost indistinguishable based on morphological characteristics. The use of molecular markers has proven to be a useful tool for revealing cryptic species complexes and here we use seven mitochondrial and nuclear gene fragments to study possible genetic differentiation among seven Aphidiinae generalists. Maximum likelihood (ML) trees and Bayesian Poisson tree processes (bPTP) models...

Data from: "De novo assembly transcriptome for the rostrum dace (Leuciscus burdigalensis, Cyprinidae: fish) naturally infected by a copepod ectoparasite" in Genomic Resources Notes accepted 1 December 2014 to 31 January 2015

Olivier Rey, Géraldine Loot, Olivier Bouchez, Simon Blanchet, Maria Jose Ruiz-Lopez, Nelson Ting, Paul D. Etter, Eric A. Johnson, Tony L. Goldberg, Colin A. Chapman, James H. Jones, Patrick A. Omeja & William M. Switzer
The emergence of pathogens represents substantial threats to public health, livestock, domesticated animals, and biodiversity. How wild populations respond to emerging pathogens has generated a lot of interest in the last two decades. With the recent advent of high-throughput sequencing technologies it is now possible to develop large transcriptomic resources for non-model organisms, hence allowing new research avenues on the immune responses of hosts from a large taxonomic spectra. We here focused on a wild...

Data from: Automixis in Artemia: solving a century-old controversy

Odrade Nougué, Nicolas O. Rode, Roula Zahab, Adeline Ségard, Luis-Miguel Chevin, Christoph R. Haag, Thomas Lenormand & R. Jabbour-Zahab
Parthenogenesis (reproduction through unfertilized eggs) encompasses a variety of reproduction modes with (automixis) or without (apomixis) meiosis. Different modes of automixis have very different genetic and evolutionary consequences but can be particularly difficult to tease apart. In this paper, we propose a new method to discriminate different types of automixis from population-level genetic data. We apply this method to diploid Artemia parthenogenetica, a crustacean whose reproductive mode remains controversial despite a century of intensive cytogenetic...

Data from: A comparison between transcriptome sequencing and 16S metagenomics for detection of bacterial pathogens in wildlife

Maria Razzauti, Maxime Galan, Maria Bernard, Sarah Maman, Christophe Klopp, Nathalie Charbonnel, Muriel Vayssier-Taussat, Marc Eloit & Jean-François Cosson
Background: Rodents are major reservoirs of pathogens responsible for numerous zoonotic diseases in humans and livestock. Assessing their microbial diversity at both the individual and population level is crucial for monitoring endemic infections and revealing microbial association patterns within reservoirs. Recently, NGS approaches have been employed to characterize microbial communities of different ecosystems. Yet, their relative efficacy has not been assessed. Here, we compared two NGS approaches, RNA-Sequencing (RNA-Seq) and 16S-metagenomics, assessing their ability to...

Data from: Microsatellite evolutionary rate and pattern in Schistocerca gregaria inferred from direct observation of germline mutations

Marie-Pierre Chapuis, Christophe Plantamp, Réjane Streiff, Laurence Blondin, Cyril Piou, R. Streiff, M.-P. Chapuis, C. Piou, L. Blondin & C. Plantamp
Unravelling variation among taxonomic orders regarding the rate of evolution in microsatellites is crucial for evolutionary biology and population genetics research. The mean mutation rate of microsatellites tends to be lower in arthropods than in vertebrates, but data are scarce and mostly concern accumulation of mutations in model species. Based on parent-offspring segregations and a hierarchical Bayesian model, the mean rate of mutation in the orthopteran insect Schistocerca gregaria was estimated at 2.1e-4 per generation...

Data from: How much would it cost to monitor farmland biodiversity in Europe?

Ilse R. Geijzendorffer, Stefano Targetti, Manuel K. Schneider, Dick J. Brus, Philippe Jeanneret, Robert H. G. Jongman, Martin Knotters, Davide Viaggi, Siyka Angelova, Michaela Arndorfer, Debra Bailey, Katalin Balzacs, András Báldim, Marion M. B. Bogers, Robert G.H. Bunce, Jean-Philippe Choisis, Peter Dennis, Sebastian Eiter, Wendy Fjellstad, Jürgen F. Friedel, Tiziano Gomiero, Arjan Griffioen, Max Kainz, Anikó Kovács-Hostyánszki, Gisela Lüscher … & András Báldi
To evaluate progress on political biodiversity objectives, biodiversity monitoring provides information on whether intended results are being achieved. Despite scientific proof that monitoring and evaluation increase the (cost) efficiency of policy measures, cost estimates for monitoring schemes are seldom available, hampering their inclusion in policy programme budgets. Empirical data collected from 12 case studies across Europe were used in a power analysis to estimate the number of farms that would need to be sampled per...

Data from: No early gender effects on energetic status and life history in a salmonid.

Thomas Regnier, Jacques Labonne, Joëlle Chat, Ayaka Yano, Yann Guiguen & Valérie Bolliet
Throughout an organism's early development, variations in physiology and behaviours may have long lasting consequences on individual life histories. While a large part of variation in critical life-history transitions remains unexplained, a significant proportion may be caused by early gender effects as part of gender-specific life histories shaped by sexual selection. In this study, we investigated the presence of early gender effects on the timing of emergence from gravel and the energetic status of brown...

Data from: Taxonomic and functional composition of arthropod assemblages across contrasting Amazonian forests

P. A. Greg Lamarre, Bruno Hérault, Paul V. A. Fine, Vincent Vedel, Roland Lupoli, Italo Mesones, Christopher Baraloto & Greg P. A. Lamarre
Arthropods represent most of global biodiversity, with the highest diversity found in tropical rainforests. Nevertheless, we have a very incomplete understanding of how tropical arthropod communities are assembled. We conducted a comprehensive mass-sampling of arthropod communities within three major habitat types of lowland Amazonian rainforest, including terra firme clay, white-sand, and seasonally-flooded forests in Peru and French Guiana. We examined how taxonomic and functional composition (at the family level) differed across these habitat types in...

Data from: Recasting the dynamic equilibrium model through a functional lens: the interplay of trait-based community assembly and climate

Jessy Loranger, Cyrille Violle, Bill Shipley, Sandra Lavorel, Anne Bonis, Pablo Cruz, Frédérique Louault, Grégory Loucougaray, François Mesléard, Nicole Yavercovski & Éric Garnier
1. According to the dynamic equilibrium hypothesis (DEH), plant species richness is locally controlled by productivity and disturbance. Given that regional conditions widely affect local environmental variables such as soil nutrient availability, the DEH predictions could be improved by considering how climate influences local controls of species richness. Further, a trait-based approach to community assembly has the potential to reveal a deeper, mechanistic understanding of species richness variation across environments. Here we bring together DEH...

Data from: Ecologically diverse and distinct neighbourhoods trigger persistent phenotypic consequences, and amine metabolic profiling detects them

Françoise Hennion, Isabelle Litrico, Igor Bartish, Alexandra Weigelt, Alain Bouchereau & Andreas Prinzing
1.Global change triggers rapid alterations in the composition and diversity of plant communities which may change ecosystem functioning. Do changes in community diversity also change traits persistently, i.e. does coexistence with numerous or functionally or phylogenetically distinct species trigger, in a given focal species, trait shifts that persist? 2.We studied the grass Dactylis glomerata. Dactylis was grown in experimental plots with different species compositions for five years, sampled, cloned and grown in a common garden....

Data from: Forest management adaptation to climate change: a Cornelian dilemma between drought resistance and soil macro-detritivore functional diversity

Ludovic Henneron, Michaël Aubert, Fabrice Bureau, Yann Dumas, François Ningre, Sandrine Perret, Claudine Richter, Philippe Balandier & Matthieu Chauvat
1. Global warming induces new constraints on forest ecosystems and requires forest management adaptation. The reduction in stand density is currently debated as a potential tool to face increasing summer drought risk by improving forest resistance to climate change-induced tree mortality. However, few studies have yet assessed the impacts of this management change on soil biodiversity. 2. We conducted a large-scale, multi-site assessment of the response of soil macro-detritivore assemblages and soil functioning to experimental...

Data from: The genetics of intra- and interspecific competitive response and effect in a local population of an annual plant species

Baron Etienne, Richirt Julien, Villoutreix Romain, Amsellem Laurent, Fabrice Roux & Etienne Baron
While competition is recognized as a major factor responsible for plant community dynamics, the genetics of intra- and interspecific competitive ability of a target species (i.e. level of intra-population genetic variation, identity of phenotypic traits under selection and genetic bases) still deserves a deeper investigation at the local spatial scale by considering both numerous genotypes and several interacting species In this study, we tested whether the genetics of competitive response and effect in Arabidopsis thaliana...

Data from: Chronic Trichuris muris Infection Decreases Diversity of the Intestinal Microbiota and Concomitantly Increases the Abundance of Lactobacilli

Jacob Bak Holm, Daniel Sorobetea, Pia Kiilerich, Yuliaxis Ramayo-Caldas, Jordi Estellé, Tao Ma, Lise Madsen, Karsten Kristiansen & Marcus Svensson-Frej
The intestinal microbiota is vital for shaping the local intestinal environment as well as host immunity and metabolism. At the same time, epidemiological and experimental evidence suggest an important role for parasitic worm infections in maintaining the inflammatory and regulatory balance of the immune system. In line with this, the prevalence of persistent worm infections is inversely correlated with the incidence of immune-associated diseases, prompting the use of controlled parasite infections for therapeutic purposes. Despite...

Data from: High genetic variation in resting stage production in a metapopulation: is there evidence for local adaptation?

Anne Carole Roulin, Mahendra Mariadassou, Matthew D. Hall, Jean-Claude Walser, Christoph Haag, Dieter Ebert & Anne C. Roulin
Local adaptation is a key process for the maintenance of genetic diversity and population diversification. A better understanding of the mechanisms that allow (or prevent) local adaptation constitutes a key in apprehending how and at what spatial scale it occurs. The production of resting stages is found in many taxa and reflects an adaptation to outlast adverse environmental conditions. Daphnia magna (Crustacea) can alternate between asexual and sexual reproduction, the latter being linked to dormancy,...

Data from: Temporal sampling helps unravel the genetic structure of naturally occurring populations of a phytoparasitic nematode. 1. Insights from the estimation of effective population sizes

Pierre-Loup Jan, Cécile Gracianne, Sylvain Fournet, Eric Olivier, Jean-Francois Arnaud, Catherine Porte, Sylvie Bardou-Valette, Marie-Christine Denis & Eric J. Petit
The sustainability of modern agriculture relies on strategies that can control the ability of pathogens to overcome chemicals or genetic resistances through natural selection. This evolutionary potential, which depends partly on effective population size (Ne), is greatly influenced by human activities. In this context, wild pathogen populations can provide valuable information for assessing the long-term risk associated with crop pests. In this study, we estimated the effective population size of the beet cyst nematode, Heterodera...

Data from: Costs of CRISPR-Cas mediated resistance in Streptococcus thermophilus

Pedro F. Vale, Guillaume Lafforgue, François Gatchitch, Rozenn Gardan, Sylvain Moineau & Sylvain Gandon
CRISPR-Cas is a form of adaptive sequence-specific immunity in microbes. This system offers unique opportunities for the study of coevolution between bacteria and their viral pathogens, bacteriophages. A full understanding of the coevolutionary dynamics of CRISPR-Cas requires knowing the magnitude of the cost of resisting infection. Here, using the gram-positive bacterium Streptococcus thermophilus and its associated virulent phage 2972, a well-established model system harbouring at least two type II functional CRISPR-Cas systems, we obtained different...

Data from: Habitat fragmentation alters the properties of a host-parasite network: rodents and their helminths in South-East Asia

Frédéric Bordes, Serge Morand, Shai Pilosof, Julien Claude, Jean-François Cosson, Yannick Chaval, Alexis Ribas, Kittipong Chaisiri, Kim Blasdell, Annelise Tran, Stéphane Dupuy & Boris R. Krasnov
1. While the effects of deforestation and habitat fragmentation on parasite prevalence or richness are well investigated, host–parasite networks are still understudied despite their importance in understanding the mechanisms of these major disturbances. Because fragmentation may negatively impact species occupancy, abundance and co-occurrence, we predict a link between spatiotemporal changes in habitat and the architecture of host–parasite networks. 2. For this, we used an extensive data set on 16 rodent species and 29 helminth species...
