Data from: Migratory divides and their consequences for dispersal, population size and parasite-host interactions

Anders P. Møller, Laszlo Z. Garamszegi, Juan M Peralta-Sánchez & Juan J. Soler
Populations of migratory birds differ in their direction of migration with neighboring populations often migrating in divergent directions separated by migratory divides. A total of 26% of 103 passerine bird species in Europe had migratory divides that were located disproportionately often along a longitudinal gradient in Central Europe, consistent with the assumption of a Quaternary glacial origin of such divides in the Iberian and Balkan peninsulas followed by re-colonization. Given that studies have shown significant...

Data from: Patterns and processes of dispersal behaviour in arvicoline rodents

Jean-François Le Galliard, Alice Rémy, Rolf A. Ims & Xavier Lambin
A good understanding of mammalian societies requires measuring patterns and comprehending processes of dispersal in each sex. We investigated dispersal behaviour in arvicoline rodents, a sub-family of mammals widespread in northern temperate environments and characterised by a multivoltine life cycle. In arvicoline rodents, variation in life history strategies occurs along a continuum from precocial to delayed maturation that reflects seasonal and ecological fluctuations. We compared dispersal across and within species focusing on the effects of...

Data from: Quantitative genetics of migration syndromes: a study of two barn swallow populations

Celine Teplitsky, Nissrine G Mouawad, Javier Balbontín, Florentino De Lope & Anders P Møller
Migration is a complex trait although little is known about genetic correlations between traits involved in such migration syndromes. To assess migratory responses to climate change, we need information on genetic constraints on evolutionary potential of arrival dates in migratory birds. Using two long term data sets on barn swallows Hirundo rustica (from Spain and Denmark), we show for the first time in wild populations that spring arrival dates are phenotypically and genetically correlated with...

Data from: Brain size and the expression of pheomelanin-based colour in birds

Ismael Galván & Anders P. Møller
Eumelanin and pheomelanin are the most common vertebrate pigments. They generate different colours and are synthesized under different physiological conditions. While pheomelanogenesis requires high levels of a key intracellular antioxidant (glutathione, GSH), eumelanogenesis is inhibited by GSH. This implies that species that present the molecular basis to produce large amounts of pheomelanin might be more limited to perform other costly processes that generate oxidative stress than species that produce eumelanin. Brain development requires large amounts...

Data from: Minimal ProtoHox cluster inferred from bilaterian and cnidarian Hox complements

Daniel Chourrout, Frédéric Delsuc, Pascal Chourrout, Rolph B Edvardsen, Fabian Rentzsch, Eduard Renfer, Marit F. Jensen, Baoli Zhu, Pieter De Jong, Robert E. Steele & Ulrich Technau
Bilaterian animals have a Hox gene cluster essential for patterning the main body axis, and a ParaHox gene cluster. Comparison of Hox and ParaHox genes has led workers to postulate that both clusters originated from the duplication of an ancient cluster named ProtoHox, which contained up to four genes with at least the precursors of anterior and posterior Hox/ParaHox genes. However, the way in which genes diversified within the ProtoHox, Hox and ParaHox clusters remains...

Data from: Within-population structure highlighted by differential introgression across semipermeable barriers to gene flow in Anguilla marmorata

Pierre Alexandre Gagnaire, Yuki Minegishi, Saliha Zenboudji, Pierre Valade, Jun Aoyama & Patrick Berrebi
In the marine environment, differential gene exchange between partially reproductively isolated taxa can result in introgression that extends over long distances due to high larval dispersal potential. However, the degree to which this process contributes to inter-locus variance of genetic differentiation within introgressed populations remains unclear. Using a genome-scan approach in the Indo-Pacific eel Anguilla marmorata, we investigated the degree of interpopulation genetic differentiation, the rate of introgression, and within-population genetic patterns at 858 AFLP...

Data from: Identifying insecticide resistance genes in mosquito by combining AFLP genome scan and 454 pyrosequencing

Margot Paris & Laurence Despres
AFLP-based genome scans are widely used to study the genetics of adaptation and to identify genomic regions potentially under selection. However, this approach usually fails to detect the actual genes or mutations targeted by selection due to the difficulty to obtain the sequences from AFLP fragments. Here we combine classical AFLP outlier detection to 454 sequencing of AFLP fragments obtained from chosen individuals to obtain the sequence of outliers. We applied this approach to the...

Data from: Diversification in temporally heterogeneous environments: effect of the grain in experimental bacterial populations.

Patrick A Venail, Nicolas Mouquet, Oliver Kaltz, Isabelle Olivieri & Thomas Pommier
Although theory established the necessary conditions for diversification in temporally heterogeneous environments, empirical evidence remains controversial. One possible explanation is the difficulty of designing experiments including the relevant range of temporal grains and the appropriate environmental tradeoffs. Here, we experimentally explore the impact of the grain on the diversification of the bacterium Pseudomonas fluorescens SBW25 in a temporally fluctuating environment by including twenty different pairs of environments and four temporal grains. In general, higher levels...

Data from: Negative frequency-dependent selection of sexually antagonistic alleles in Myodes glareolus

Mikael Mokkonen, Hanna Kokko, Esa Koskela, Jussi Lehtonen, Tapio Mappes, Henna Martiskainen & Suzanne C. Mills
Sexually antagonistic genetic variation, where optimal values of traits are sex-dependent, is known to slow the loss of genetic variance associated with directional selection on fitness-related traits. However, sexual antagonism alone is not sufficient to maintain variation indefinitely. Selection of rare forms within the sexes can help to conserve genotypic diversity. We combined theoretical models and a field experiment with Myodes glareolus to show that negative frequency-dependent selection on male dominance maintains variation in sexually...

Data from: Catching-up but telomere loss: half-opening the black box of growth and ageing trade-off in wild king penguin chicks

Sylvie Geiger, Maryline Le Vaillant, Thomas Lebard, Sophie Reichert, Antoine Stier, Yvon Le Maho & Francois Criscuolo
One of the reasons for animals not to grow as fast as they potentially could is that fast growth has been shown to be associated with reduced lifespan. However, we are still lacking a clear description of the reality of growth-dependent modulation of ageing mechanisms in wild animals. Using the particular growth trajectory of small king penguin chicks naturally exhibiting higher-than-normal growth rate to compensate for the winter break, we tested whether oxidative stress and...

Data from: Soil sampling and isolation of extracellular DNA from large amount of starting material suitable for metabarcoding studies

Pierre Taberlet, Sophie M. Prud'homme, Etienne Campione, Julien Roy, Christian Miquel, Wasim Shehzad, Ludovic Gielly, Delphine Rioux, Philippe Choler, Jean-Christophe Clément, Christelle Melodelima, François Pompanon & Eric Coissac
DNA metabarcoding corresponds to the DNA-based identification of multiple species from a single complex and degraded environmental sample. We developed new sampling and extraction protocols suitable for DNA metabarcoding analyses, targeting soil extracellular DNA. The proposed sampling protocol has been designed to reduce as much as possible the influence of the local heterogeneity by processing large amount of soil, resulting from the mixing of many different cores. The DNA extraction is based on the use...

Data from: Tunicate mitogenomics and phylogenetics: peculiarities of the Herdmania momus mitochondrial genome and support for the new chordate phylogeny

Tiratha R. Singh, Georgia Tsagkogeorga, Frédéric Delsuc, Samuel Blanquart, Noa Shenkar, Lossi Loya, Emmanuel J. P. Douzery & Dorothée Huchon
BACKGROUND: Tunicates represent a key metazoan group as the sister-group of vertebrates within chordates. The six complete mitochondrial genomes available so far for tunicates have revealed distinctive features. Extensive gene rearrangements and particularly high evolutionary rates have been evidenced with regard to other chordates. This peculiar evolutionary dynamics has hampered the reconstruction of tunicate phylogenetic relationships within chordates based on mitogenomic data. RESULTS: In order to further understand the atypical evolutionary dynamics of the mitochondrial...

Data from: Genetic structure in a dynamic baboon hybrid zone corroborates behavioral observations in a hybrid population

Marie J.E. Charpentier, Michael C. Fontaine, Julien P. Renoult, Thomas Jenkins, Erwan Cherel, Laure Benoit, Nicolas Barthès, Susan C. Alberts & Jenny Tung
Behavior and genetic structure are intimately related: mating patterns and patterns of movement between groups or populations influence the movement of genetic variation across the landscape and from one generation to the next. In hybrid zones, the behavior of the hybridizing taxa can also have an important impact on the incidence and outcome of hybridization events. Hybridization between yellow baboons and anubis baboons has been well-documented in the Amboseli basin of Kenya, where more anubis-like...

Data from: A new malaria agent in African hominids.

Benjamin Ollomo, Patrick Durand, Franck Prugnolle, Emmanuel J. P. Douzery, Céline Arnathau, Dieudonné Nkoghe, Eric Leroy & François Renaud
Plasmodium falciparum is the major human malaria agent responsible for 200 to 300 million infections and one to three million deaths annually, mainly among African infants. The origin and evolution of this pathogen within the human lineage is still unresolved. A single species, P. reichenowi, which infects chimpanzees, is known to be a close sister lineage of P. falciparum. Here we report the discovery of a new Plasmodium species infecting Hominids. This new species has...

Data from: Variation in patriline reproductive success during queen production in orphaned colonies of the thelytokous ant Cataglyphis cursor

Blandine Chéron, Thibaud Monnin, Pierre Fédérici & Claudie Doums
In genetically diverse insect societies (polygynous or polyandrous queens), the production of new queens can set the ground for competition among lineages. This competition can be very intense when workers can reproduce using thelytoky as worker patrilines that manage to produce new queens gain a huge benefit. Selection at the individual level might then lead to the evolution of cheating genotypes, i.e. genotypes that reproduce more than their fair share. We studied the variation in...

Data from: Scale-specific sex-biased dispersal in the Valais shrew unveiled by genetic variation on the Y chromosome, autosomes, and mitochondrial DNA

Glenn Yannic, Patrick Basset, Lucie Büchi, Jacques Hausser & Thomas Broquet
We investigated sex-specificities in the evolutionary processes shaping Y chromosome, autosomes and mitochondrial DNA patterns of genetic structure in the Valais shrew (Sorex antinorii), a mountain dwelling species with a hierarchical distribution. Both hierarchical analyses of variance and isolation-by-distance analyses revealed patterns of population structure that were not consistent across maternal, paternal and bi-parentally inherited markers. Differentiation on a Y microsatellite was lower than expected from the comparison with autosomal microsatellites and mtDNA, and it...

Data from: Testicular melanization has evolved in birds with high mtDNA mutation rates

Ismael Galván, Anders P. Møller & Johannes Erritzøe
Melanin is mainly found in the integument of animals, but it also appears in several extracutaneous tissues. The presence of melanin in testes has been anecdotally reported in all vertebrate groups, but the causes and functions of this melanin remain unknown. Similar to other extracutaneous melanins, testicular melanin may protect male germ cells from oxidative stress. Given the high respiratory activity of spermatozoa, oxidative stress generated by mitochondrial dysfunction as a consequence of mtDNA mutations...

Data from: Comparing the genetic architecture and potential response to selection of native and invasive populations of reed canary grass

Brittny Calsbeek, Manisha Patel, Sebastien Lavergne & Jane Molofsky
Evolutionary processes such as migration, genetic drift, and natural selection are thought to play a prominent role in species invasions into novel environments. However, few empirical studies have explored the mechanistic basis of invasion in an evolutionary framework. One promising tool for inferring evolutionarily important changes in introduced populations is the genetic variance-covariance matrix (G matrix). G matrix comparisons allow for the inference of changes in the genetic architecture of introduced populations relative to their...

Data from: High-throughput microsatellite isolation through 454 GS-FLX Titanium pyrosequencing of enriched DNA libraries

Thibaut Malausa, André Gilles, Emese Meglécz, Hélène Blanquart, Stéphanie Duthoy, Caroline Costedoat, Vincent Dubut, Nicolas Pech, Philippe Castagnone-Sereno, Christophe Délye, Nicolas Feau, Pascal Frey, Philippe Gauthier, Thomas Guillemaud, Laurent Hazard, Valérie Le Corre, Brigitte Lung-Escarmant, Pierre-Jean G Malé, Stéphanie Ferreira & Jean-François Martin
Microsatellites (or SSR: simple sequence repeat) are among the most frequently used DNA markers in many areas of research. The use of microsatellite markers is limited by the difficulties involved in their de novo isolation from species for which no genomic resources are available. We describe here a high-throughput method for isolating microsatellite markers based on coupling multiplex microsatellite enrichment and Next-Generation Sequencing on 454 GS-FLX Titanium platforms. The procedure was calibrated on a model...

Data from: Tracking earthworm communities from soil DNA

Friederike Bienert, Sébastien De Danieli, Christian Miquel, Eric Coissac, Carole Poillot, Jean-Jacques Brun & Pierre Taberlet
Earthworms are known for their important role within the functioning of an ecosystem, and their diversity can be used as an indicator of ecosystem health. To date, earthworm diversity has been investigated through conventional extraction methods such as handsorting, soil washing or the application of a mustard solution. Such techniques are time-consuming and often difficult to apply. We showed that combining DNA metabarcoding and next generation sequencing facilitates the identification of earthworm species from soil...

Data from: Diversity patterns of uncultured Haptophytes unravelled by pyrosequencing in Naples Bay

Lucie Bittner, Angélique Gobet, Stéphane Audic, Sarah Romac, Elianne S. Egge, Sébastien Santini, Hiroyuki Ogata, Ian Probert, Bente Edvardsen & Colomban De Vargas
Haptophytes are a key phylum of marine protists, including ~300 described morphospecies and 80 morphogenera. We used 454 pyrosequencing on large subunit ribosomal DNA (LSU rDNA) fragments to assess the diversity from size-fractioned plankton samples collected in the Bay of Naples. One group-specific primer set targeting the LSU rDNA D1/D2 region was designed to amplify Haptophyte sequences from nucleic acid extracts (total DNA or RNA) of two size fractions (0.8–3 or 3–20 μm) and two...

Data from: Inter-island divergence within Drosophila mauritiana, a species of the D. simulans complex: past history and/or speciation in progress?

Delphine Legrand, Thomas Chenel, Cécile Campagne, Daniel Lachaise & Marie-Louise Cariou
Speciation with gene flow may be more common than generally thought making detailed understanding of the extent and pattern of genetic divergence between geographically isolated populations useful. Species of the Drosophila simulans complex provide a good model for speciation and evolutionary studies; understanding their population genetic structure will increase our understanding of the context in which speciation has occurred. Here we describe the genetic diversity and the genetic differentiation, at mitochondrial and nuclear loci, of...

Data from: Host and habitat specialization of avian malaria in Africa

Claire Loiseau, Ryan J. Harrigan, Alexandre Robert, Rauri C. K. Bowie, Henri A. Thomassen, Thomas B. Smith & Ravinder N. M. Sehgal
Studies of both vertebrates and invertebrates have suggested that specialists, as compared to generalists, are likely to suffer more serious declines in response to environmental change. Less is known about the effects of environmental conditions on specialist vs. generalist parasites. Here, we study the evolutionary strategies of malaria parasites (Plasmodium spp.) among different bird host communities. We determined the parasite diversity and prevalence of avian malaria in three bird communities in the lowland forests in...

Data from: Ecological speciation in dynamic landscapes

Robin Aguilée, Amaury Lambert & David Claessen
Although verbal theories of speciation consider landscape changes, ecological speciation is usually modeled in a fixed geographical arrangement. Yet landscape changes occur, at different spatio-temporal scales, due to geological, climatic or ecological processes, and these changes result in repeated divisions and reconnections of populations. We examine the effect of such landscape dynamics on speciation. We use a stochastic, sexual population model with polygenic inheritance, embedded in a landscape dynamics model (allopatry-sympatry oscillations). We show that,...

Data from: Differential selection between the sexes and selection for sex

Denis Roze & Sarah P. Otto
Anisogamy is known to generate an important cost for sexual reproduction (the famous "twofold cost of sex"). However, male-female differences may have other consequences on the evolution of sex, due to the fact that selective pressures may differ among the sexes. On the one hand, intralocus sexual conflict should favor asexual females, which can fix female-beneficial, male-detrimental alleles. On the other hand, it has been suggested repeatedly that sexual selection among males may help to...
