Data from: Sexual selection on song and cuticular hydrocarbons in two distinct populations of Drosophila montana

Paris Veltsos, Claude Wicker-Thomas, Roger K. Butlin, Anneli Hoikkala & Michael G. Ritchie
Sexual selection has the potential to contribute to population divergence and speciation. Most studies of sexual selection in Drosophila have concentrated on a single signaling modality, usually either courtship song or cuticular hydrocarbons (CHCs), which can act as contact pheromones. We have examined the relationship between both signal types and reproductive success using F1-3 offspring of wild-collected flies, raised in the lab. We used two populations of the Holarctic species Drosophila montana, that represent different...

Data from: Testing gradual and speciational models of evolution in extant taxa: the example of ratites

Michel Laurin, Sander W.S. Gussekloo, David Marjanovic, Lucas Legendre & Jorge Cubo
Ever since Eldredge and Gould proposed their model of punctuated equilibria, evolutionary biologists have debated how often this model is the best description of nature and how important it is compared to the more gradual models of evolution expected from natural selection and the neo-Darwinian paradigm. Recently, Cubo proposed a method to test whether morphological data in extant ratites are more compatible with a gradual or with a speciational model (close to the punctuated equilibrium...

Data from: Effects of parasitic sex-ratio distorters on host genetic structure in the Armadillidium vulgare-Wolbachia association

Sébastien Verne, Monique Johnson, Didier Bouchon & Frédéric Grandjean
In the pill bug Armadillidium vulgare (Crustacea, Oniscidea) Wolbachia facilitates its spread through vertical transmission via the eggs by inducing feminization of genetic males. The spread of feminizing Wolbachia within and across populations is therefore expected to influence mtDNA genetic structure by hitchhiking. To test this hypothesis, we analysed nuclear and mtDNA genetic structure, and Wolbachia prevalence in 13 populations of the pill bug host. Wolbachia prevalence (ranging from 0 to 100% of sampled females)...

Data from: Islands in the ice: detecting past vegetation on Greenlandic nunataks using historical records and sedimentary ancient DNA meta-barcoding

Tina Jørgensen, Kurt H Kjær, James Haile, Morten Rasmussen, Sanne Boessenkool, Kenneth Andersen, Eric Coissac, Pierre Taberlet, Christian Brochmann, Ludovic Orlando, M. Thomas P. Gilbert & Eske Willerslev
Nunataks are isolated bedrocks protruding through ice sheets. They vary in age, but represent island environments in “oceans” of ice through which organism dispersals and replacements can be studied over time. The J.A.D. Jensen’s Nunataks at the southern Greenland ice sheet are the most isolated nunataks on the northern hemisphere - some 30 km from the nearest biological source. They constitute around 2 km2 of ice-free land that was established in the early Holocene. We...

Data from: A comparative study of ancient sedimentary DNA, pollen and macrofossils from permafrost sediments of northern Siberia reveals long-term vegetational stability

Tina Jørgensen, James Haile, Per Möller, Andrei Andreev, Sanne Boessenkool, Morten Rasmussen, Frank Kienast, Eric Coissac, Pierre Taberlet, Christian Brochmann, Nancy H. Bigelow, Kenneth Andersen, Ludovic Orlando, M. Thomas P. Gilbert & Eske Willerslev
Although ancient DNA from sediments (sedaDNA) has been used to investigate past ecosystems, the approach has never been directly compared to the traditional methods of pollen and macrofossil analysis. We conducted a comparative survey of 18 ancient permafrost samples spanning the Late Pleistocene (46–12.5 thousand years ago), from the Taymyr Peninsula in northern Siberia. The results show that pollen, macrofossils and sedaDNA are complementary rather than overlapping, and in combination reveal more detailed information on...

Data from: An updated 18S rRNA phylogeny of tunicates based on mixture and secondary structure models

Georgia Tsagkogeorga, Xavier Turon, Russell R. Hopcroft, Marie-Ka Tilak, Tamar Feldstein, Noa Shenkar, Yossi Loya, Dorothée Huchon, Emmanuel J. P. Douzery & Frédéric Delsuc
BACKGROUND: Tunicates have been recently revealed to be the closest living relatives of vertebrates. Yet, with more than 2500 described species, details of their evolutionary history are still obscure. From a molecular point of view, tunicate phylogenetic relationships have been mostly studied based on analyses of 18S rRNA sequences, which indicate several major clades at odds with the traditional class-level arrangements. Nonetheless, substantial uncertainty remains about the phylogenetic relationships and taxonomic status of key groups...

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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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: 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...
