Data from: Senescence rates and late adulthood reproductive success are strongly influenced by personality in a long lived seabird

Samantha C. Patrick & Henri Weimerskirch
Studies are increasingly demonstrating that individuals differ in their rate of ageing, and this is postulated to emerge from a trade-off between current and future reproduction. Recent theory predicts a correlation between individual personality and life-history strategy, and from this comes the prediction that personality may predict the intensity of senescence. Here we show that boldness correlates with reproductive success and foraging behaviour in wandering albatrosses, with strong sex-specific differences. Shy males show a strong...

Data from: Postglacial climate changes and rise of three ecotypes of harbor porpoises, Phocoena phocoena, in western Palearctic waters

Michaël C. Fontaine, Kathleen Roland, Isabelle Calves, Frederic Austerlitz, Friso P. Palstra, Krystal A. Tolley, Sean Ryan, Marisa Ferreira, Thierry Jauniaux, Angela Llavona, Bayram Öztürk, Ayaka A. Öztürk, Vincent Ridoux, Emer Rogan, Ursula Siebert, Marina Sequeira, Gísli A. Vikingsson, Asunción Borrell, Johan R. Michaux & Alex Aguilar
Despite no obvious barriers to gene flow in the marine realm, environmental variation and ecological specializations can lead to genetic differentiation in highly mobile predators. Here, we investigated the genetic structure of the harbor porpoise over the entire species distribution range in western Palearctic waters. Combined analyses of ten microsatellite loci and a 5,085 bases-pairs portion of the mitochondrial genome revealed the existence of three ecotypes, equally divergent at the mitochondrial genome, distributed in the...

Data from: Genetic structure of populations of whale sharks among ocean basins and evidence for their historic rise and recent decline

Thomas M. Vignaud, Jeffrey A. Maynard, Raphael Leblois, Mark G. Meekan, Ricardo Vázquez-Juárez, Dení Ramírez-Macías, Simon J. Pierce, David Rowat, Michael L. Berumen, Champak Beeravolu, Sandra Baksay & Serge Planes
This study presents genetic evidence that whale sharks, Rhincodon typus, are comprised of at least two populations that rarely mix and is the first to document a population expansion. Relatively high genetic structure is found when comparing sharks from the Gulf of Mexico with sharks from the Indo-Pacific. If mixing occurs between the Indian and Atlantic Oceans, it is not sufficient to counter genetic drift. This suggests whale sharks are not all part of a...

Data from: C, N, and P fertilization in an Amazonian rainforest support stoichiometric dissimilarity as a driver of litter diversity effects on decomposition

Sandra Barantal, Heidy Schimann, Nathalie Fromin & Stephan Hättenschwiler
Plant leaf litter generally decomposes faster as a group of different species than when individual species decompose alone, but underlying mechanisms of these diversity effects remain poorly understood. Because resource C : N : P stoichiometry (i.e. the ratios of these key elements) exhibits strong control on consumers, we supposed that stoichiometric dissimilarity of litter mixtures (i.e. the divergence in C : N : P ratios among species) improves resource complementarity to decomposers leading to...

Data from: Re-visiting the phylogeography and demography of European badgers (Meles meles) based on broad sampling, multiple markers and simulations

Clements, Morten Elmeros, Guillem Molina-Vacas, Aritz Ruiz-Gonzalez, Alessandro Balestrieri, Koen Van Den Berge, Peter Breyne, Emmanuel Do Linh San, Erik O. Ågren, Franz Suchentrunk, Laurent Schley, Rafał Kowalczyk, Berit I. Kostka, Dusko Ćirović, Nikica Šprem, Marc Colyn, Marco Ghirardi, Venislava Racheva, Christophe Braun, Rita Oliveira … & Terry Burke
Although the phylogeography of European mammals has been extensively investigated since the 1990s, many studies were limited in terms of sampling distribution, the number of molecular markers used and the analytical techniques employed, frequently leading to incomplete postglacial recolonisation scenarios. The broad-scale genetic structure of the European badger (Meles meles) is of interest as it may result from historic restriction to glacial refugia and/or recent anthropogenic impact. However, previous studies were based mostly on samples...

Data from: Multidimensionality in host manipulation mimicked by serotonin injection

Marie-Jeanne Perrot-Minnot, Kevin Sanchez-Thirion & Frank Cézilly
Manipulative parasites often alter the phenotype of their hosts along multiple dimensions. ‘Multidimensionality’ in host manipulation could consist in the simultaneous alteration of several physiological pathways independently of one another, or proceed from the disruption of some key physiological parameter, followed by a cascade of effects. We compared multidimensionality in ‘host manipulation’ between two closely related amphipods, Gammarus fossarum and Gammarus pulex, naturally and experimentally infected with Pomphorhynchus laevis (Acanthocephala), respectively. To that end, we...

Data from: Selection for sex in finite populations

Denis Roze
Finite population size generates interference between selected loci, which has been shown to favour increased rates of recombination. In this article, I present different analytical models exploring selection acting on a ‘sex modifier locus’ (that affects the relative investment into asexual and sexual reproduction) in a finite population. Two forms of selective forces act on the modifier: direct selection due to intrinsic costs associated with sexual reproduction and indirect selection generated by one or two...

Data from: Heritable variation in host tolerance and resistance inferred from a wild host– parasite system

Elise Mazé-Guilmo, Géraldine Loot, David James Páez, Thierry Lefèvre, Simon Blanchet, T. Lefevre, D. J. Paez & E. Maze-Guilmo
Hosts have evolved two distinct defence strategies against parasites: resistance (which prevents infection or limit parasite growth) and tolerance (which alleviates the fitness consequences of infection). However, heritable variation in resistance and tolerance and the genetic correlation between these two traits have rarely been characterized in wild host populations. Here, we estimate these parameters for both traits in Leuciscus burdigalensis, a freshwater fish parasitized by Tracheliastes polycolpus. We used a genetic database to construct a...

Data from: Across-year social stability shapes network structure in wintering migrant sparrows

Daizaburo Shizuka, Alexis S. Chaine, Jennifer Anderson, Oscar Johnson, Inger Marie Laursen & Bruce E. Lyon
Migratory birds often form flocks on their wintering grounds, but important details of social structure such as the patterns of association between individuals are virtually unknown. We analysed networks of co-membership in short-term flocks for wintering golden-crowned sparrows (Zonotrichia atricapilla) across three years and discovered social complexity unsuspected for migratory songbirds. The population was consistently clustered into distinct social communities within a relatively small area (~ 7 ha). Birds returned to the same community across...

Data from: A quantitative review of MHC-based mating preference: the role of diversity and dissimilarity

T. Kamiya, K. O'Dwyer, H. Westerdahl, A. Senior & S. Nakagawa
Sexual selection hypotheses stipulate that the major histocompatibility complex genes (MHC) constitute a key molecular underpinning for mate choice in vertebrates. The last four decades saw growing empirical literature on the role of MHC diversity and dissimilarity in mate choice for a wide range of vertebrate animals, but with mixed support for its significance in natural populations. Using formal phylogenetic meta-analysis and meta-regression techniques, we quantitatively review the existing literature on MHC-dependent mating preferences in...

Data from: Evidence of genetic change in the flowering phenology of sea beets along a latitudinal cline within two decades

Henk Van Dijk & Nina C. Hautekèete
Sea beets grown from seeds collected in 1989 and 2009 along the coasts of France and adjacent regions were compared for flowering date under controlled conditions. Seeds from both collection years were sown simultaneously and cultivated under the same glasshouse conditions. Date of flowering onset and year of first flowering were recorded. There was an overall northward shift in flowering time of about 0.35° latitude (i.e. 39 km) over the 20 year period. The southern...

Data from: Consistency pays: sex differences and fitness consequences of behavioural specialisation in a wide ranging seabird

Samantha C. Patrick & Henri Weimerskirch
Specialists and generalists often coexist within a single population, but the biological drivers of individual strategies are not fully resolved. When sexes differ in their foraging strategy, this can lead them to different environmental conditions and stability across their habitat range. As such, sexual segregation, combined with dominance, may lead to varying levels of specialization between the sexes. Here, we examine spatial and temporal niche width (intraindividual variability in aspects of foraging behaviour) of male...

Data from: Morphological vs. molecular delineation of taxa across montane regions in Europe: the case study of Gammarus balcanicus Schäferna, 1922 (Crustacea: Amphipoda)

Tomasz Mamos, Remi Wattier, Aneta Majda, Boris Sket & Michał Grabowski
Mountainous areas are characterized by substantial biodiversity and endemicity due to their complex geological history and habitat fragmentation. Hence, it can be assumed that particularly high species richness can be found in organisms with limited dispersal capabilities that inhabit mountain streams. A number of scientific papers focus on molecular phylogeography or traditional taxonomy of species or species groups inhabiting such habitats. However, there is a lack of studies that integrate morphological and molecular data to...

Data from: Microsatellite markers from the Ion Torrent: a multi-species contrast to 454 shotgun sequencing

Carole P. Elliott, Neal J. Enright, Richard J. N. Allcock, Michael G. Gardner, Emese Meglécz, Janet Anthony & Siegfried L. Krauss
The development and screening of microsatellite markers have been accelerated by next-generation sequencing (NGS) technology and in particular GS-FLX pyro-sequencing (454). More recent platforms such as the PGM semiconductor sequencer (Ion Torrent) offer potential benefits such as dramatic reductions in cost, but to date have not been well utilized. Here, we critically compare the advantages and disadvantages of microsatellite development using PGM semiconductor sequencing and GS-FLX pyro-sequencing for two gymnosperm (a conifer and a cycad)...

Data from: Does recognized genetic management in supportive breeding prevent genetic changes in life-history traits?

Rémi Chargé, Gabriele Sorci, Michel Saint Jalme, Loïc Lesobre, Yves Hingrat, Frédéric Lacroix & Celine Teplitsky
Supportive breeding is one of the last resort conservation strategies to avoid species extinction. Management of captive populations is challenging because several harmful genetic processes need to be avoided. Several recommendations have been proposed to limit these deleterious effects, but empirical assessments of these strategies remain scarce. We investigated the outcome of a genetic management in a supportive breeding for the Houbara Bustard. At the phenotypic level, we found an increase over generations in the...

Data from: Genetic architecture of inbreeding depression and the maintenance of gametophytic self-incompatibility

Camille Elsa Gervais, Diala Abu Awad, Denis Roze, Vincent Castric, Sylvain Billiard & Camille Gervais
Gametophytic self-incompatibility is a widespread genetic system, which enables hermaphroditic plants to avoid self-fertilization and mating with close relatives. Inbreeding depression is thought to be the major force maintaining self-incompatibility; however, inbreeding depression is a dynamical variable that depends in particular on the mating system. In this paper we use multilocus, individual based simulations to examine the co-evolution of self-incompatibility and inbreeding depression within finite populations. We focus on the conditions for the maintenance of...

Data from: One tree to link them all: a phylogenetic dataset for the European Tetrapoda

Cristina Roquet, Sébastien Lavergne & Wilfried Thuiller
Since the ever-increasing availability of phylogenetic informative data, the last decade has seen an upsurge of ecological studies incorporating information on evolutionary relationships among species. However, detailed species-level phylogenies are still lacking for many large groups and regions, which are necessary for comprehensive large-scale eco-phylogenetic analyses. Here, we provide a dataset of 100 dated phylogenetic trees for all European tetrapods based on a mixture of supermatrix and supertree approaches. Phylogenetic inference was performed separately for...

Data from: Sex in an uncertain world: environmental stochasticity helps restore competitive balance between sexually and asexually reproducing populations

Andrew W. Park, Jochen Vandekerkhove & Yannis Michalakis
Like many organisms, individuals of the freshwater ostracod species Eucypris virens can have either obligate sexual or asexual reproductive modes. Both types of individual routinely co-occur, including in the same temporary freshwater pond (their natural habitat in which they undergo seasonal diapause). Given the well-known two-fold cost of sex, this begs the question of how sexually reproducing individuals are able to co-exist with their asexual counterparts in spite of such overwhelming costs. Environmental stochasticity in...

Data from: Diet quality in a wild grazer declines under the threat of an ambush predator

Florian Barnier, Marion Valeix, Patrick Duncan, Simon Chamaillé-Jammes, Philippe Barre, Andrew J. Loveridge, David W. Macdonald, Hervé Fritz & S. Chamaille-Jammes
Predators influence prey populations not only through predation itself, but also indirectly through prompting changes in prey behaviour. The behavioural adjustments of prey to predation risk may carry nutritional costs, but this has seldom been studied in the wild in large mammals. Here, we studied the effects of an ambush predator, the African lion (Panthera leo), on the diet quality of plains zebras (Equus quagga) in Hwange National Park, Zimbabwe. We combined information on movements...

Data from: Performance of individual vs group sampling for inferring dispersal under isolation by distance

Natacha Luximon, Eric J. Petit & Thomas Broquet
Models of isolation-by-distance formalize the effects of genetic drift and gene flow in a spatial context where gene dispersal is spatially limited. These models have been used to show that, at an appropriate spatial scale, dispersal parameters can be inferred from the regression of genetic differentiation against geographic distance between sampling locations. This approach is compelling because it is relatively simple and robust, and has rather low sampling requirements. In continuous populations, dispersal can be...

Data from: Meteorological conditions influence short-term survival and dispersal in a reinforced bird population.

Loïc A. Hardouin, Alexandre Robert, Marie Nevoux, Olivier Gimenez, Frederic Lacroix & Yves Hingrat
A high immediate mortality rate of released animals is an important cause of translocation failure (“release cost”). Post-release dispersal (i.e. the movements from the release site to the first breeding site) has recently been identified as another source of local translocation failure. In spite of their potential effects on conservation program outcomes, little is known about the quantitative effects of these two sources of translocation failure and their interactions with environmental factors and management designs....

Data from: Cultural evolution of systematically structured behaviour in a non-human primate

Nicolas Claidière, Kenny Smith, Simon Kirby & Joël Fagot
Culture pervades human life and is at the origin of the success of our species. A wide range of other animals have culture too, but often in a limited form that does not complexify through the gradual accumulation of innovations. We developed a new paradigm to study cultural evolution in primates in order to better evaluate our closest relatives' cultural capacities. Previous studies using transmission chain experimental paradigms, in which the behavioural output of one...
