Data from: Assessment of a 16S rRNA amplicon Illumina sequencing procedure for studying the microbiome of a symbiont-rich aphid genusEmmanuelle Jousselin, Anne-Laure Clamens, Maxime Galan, Maria Bernard, Sarah Maman, Bernhard Gschloessl, Marie-Gabrielle Duport, Andrea S. Meseguer, Federica Calevro, Armelle Coeur D'acier, G. Duport & A.-L. Clamens
The bacterial communities inhabiting arthropods are generally dominated by a few endosymbionts that play an important role in the ecology of their hosts. Rather than comparing bacterial species richness across samples, ecological studies on arthropod endosymbionts often seek to identify the main bacterial strains associated with each specimen studied. The filtering out of contaminants from the results and the accurate taxonomic assignment of sequences are therefore crucial in arthropod microbiome studies. We aimed here to...
Capture–recapture software packages have proven to be very powerful tools for analysing factors affecting survival in wild populations. However, all such packages are limited to discrete-time protocols. Appropriate survival analysis tools are still lacking for data acquired from continuous-time protocols. We have developed a statistical method and propose an r package for analysing such data based on an extension of classical survival analysis models incorporating an inhomogeneous Poisson process for modelling capture histories. First, data...
Data from: Molecular phylogeny of the highly diversified catfish subfamily Loricariinae (Siluriformes, Loricariidae) reveals incongruences with morphological classificationRaphaël Covain, Sonia Fisch-Muller, Claudio Oliveira, Jan H. Mol, Juan I. Montoya-Burgos & Stéphane Dray
The Loricariinae belong to the Neotropical mailed catfish family Loricariidae, the most species-rich catfish family. Among loricariids, members of the Loricariinae are united by a long and flattened caudal peduncle and the absence of an adipose fin. Despite numerous studies of the Loricariidae, there is no comprehensive phylogeny of this morphologically highly diversified subfamily. To fill this gap, we present a molecular phylogeny of this group, including 350 representatives, based on the analysis of mitochondrial...
Data from: Microsatellite evolutionary rate and pattern in Schistocerca gregaria inferred from direct observation of germline mutationsMarie-Pierre Chapuis, Christophe Plantamp, Réjane Streiff, Laurence Blondin, Cyril Piou & M.-P. Chapuis
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...
1. Animal space use has been studied by focusing either on geographic (e.g. home ranges, species' distribution) or on environmental (e.g. habitat use and selection) space. However, all patterns of space use emerge from individual movements, which are the primary means by which animals change their environment. 2. Individuals increase their use of a given area by adjusting two key movement components: the duration of their visit and/or the frequency of revisits. Thus, in spatially...
Data from: Spatiotemporal spike coding of behavioral adaptation in the dorsal anterior cingulate cortexLaureline Logiaco, René Quilodran, Emmanuel Procyk & Angelo Arleo
The frontal cortex controls behavioral adaptation in environments governed by complex rules. Many studies have established the relevance of firing rate modulation after informative events signaling whether and how to update the behavioral policy. However, whether the spatiotemporal features of these neuronal activities contribute to encoding imminent behavioral updates remains unclear. We investigated this issue in the dorsal anterior cingulate cortex (dACC) of monkeys while they adapted their behavior based on their memory of feedback...
Data from: A non-lethal sampling method to obtain, generate and assemble whole-blood transcriptomes from small, wild mammalsZixia Huang, Aurore Gallot, Nga T. Lao, Sébastien J. Puechmaille, Nicole M. Foley, David Jebb, Michaël Bekaert & Emma C. Teeling
The acquisition of tissue samples from wild populations is a constant challenge in conservation biology, especially for endangered species and protected species where nonlethal sampling is the only option. Whole blood has been suggested as a nonlethal sample type that contains a high percentage of bodywide and genomewide transcripts and therefore can be used to assess the transcriptional status of an individual, and to infer a high percentage of the genome. However, only limited quantities...
Data from: Bayesian phylogeographic inferences reveal contrasting colonization dynamics among European groundwater isopodsDavid Eme, Florian Malard, Lara Konecny-Dupré, Tristan Lefébure & Christophe J. Douady
The potentially important role of northern microrefugia during postglacial dispersal is challenging the view of southern Europe as a refuge and source area of European biota. In groundwaters, large geographic ranges of presumably good dispersers are increasingly suspected to consist of assemblages of cryptic species with narrow ranges. Moreover, a large species range, even when confirmed by molecular evidence, tells us little about the spatiotemporal dynamics of dispersal. Here, we used phylogenetic inferences, species delineation...
Data from: Immunogenetic heterogeneity in a widespread ungulate: the European roe deer (Capreolus capreolus)Erwan Quéméré, Maxime Galan, Jean-François Cosson, François Klein, Stéphane Aulagnier, Emmanuelle Gilot-Fromont, Joël Merlet, A. J. Mark Hewison & Nathalie Charbonnel
Understanding how immune genetic variation is shaped by selective and neutral processes in wild populations is of prime importance in both evolutionary biology and epidemiology. The European roe deer (Capreolus capreolus) has considerably expanded its distribution range these last decades, notably by colonizing agricultural landscapes. This range shift is likely to have led to bottlenecks and increased roe deer exposure to a new range of pathogens that until recently predominantly infected humans and domestic fauna....
Data from: Postglacial recolonisation in a cold climate specialist in Western Europe: patterns of genetic diversity in the adder (Vipera berus) support the central-marginal hypothesisSylvain Ursenbacher, Michaël Guillon, Hervé Cubizolle, Andréaz Dupoué, Gabriel Blouin-Demers & Olivier Lourdais
Understanding the impact of postglacial recolonization on genetic diversity is essential in explaining current patterns of genetic variation. The central–marginal hypothesis (CMH) predicts a reduction in genetic diversity from the core of the distribution to peripheral populations, as well as reduced connectivity between peripheral populations. While the CMH has received considerable empirical support, its broad applicability is still debated and alternative hypotheses predict different spatial patterns of genetic diversity. Using microsatellite markers, we analysed the...
Data from: Changes in horn size of Stone's sheep over four decades correlate with trophy hunting pressureMathieu Douhard, Marco Festa-Bianchet, Fanie Pelletier, Jean-Michel Gaillard & Christophe Bonenfant
Selective harvest may lead to rapid evolutionary change. For large herbivores, trophy hunting removes males with large horns. That artificial selection, operating in opposition to sexual selection, can lead to undesirable consequences for management and conservation. There have been no comparisons of long-term changes in trophy size under contrasting harvest pressures. We analyzed horn measurements of Stone's rams (Ovis dalli stonei) harvested over 37 years in two large regions of British Columbia, Canada, with marked...
