Data from: Chromosomal rearrangements do not seem to affect the gene flow in hybrid zones between karyotypic races of the common shrew (Sorex araneus)

Agnès Horn
Chromosomal rearrangements are proposed to promote genetic differentiation between chromosomally differentiated taxa and therefore promote speciation. Due to their remarkable karyotypic polymorphism, the shrews of the Sorex araneus group were used to investigate the impact of chromosomal rearrangements on gene flow. Five intraspecific chromosomal hybrid zones characterized by different levels of karyotypic complexity were studied using 16 microsatellites markers. We observed low levels of genetic differentiation even in the hybrid zones with the highest karyotypic...

Data from: Group-size diversity in public goods games

Jorge Peña
Public goods games are models of social dilemmas where cooperators pay a cost for the production of a public good while defectors free ride on the contributions of cooperators. In the traditional framework of evolutionary game theory, the payoffs of cooperators and defectors result from interactions in groups formed by binomial sampling from an infinite population. Despite empirical evidence showing that group-size distributions in nature are highly heterogeneous, most models of social evolution assume that...

Data from: Multiple refugia and barriers explain the phylogeography of the Valais shrew, Sorex antinorii (Mammalia: Soricomorpha)

Glenn Yannic, Loïc Pellissier, Sylvain Dubey, Rodrigo Vega, Patrick Basset, Stefano Mazzotti, Elena Pecchioli, Cristiano Vernesi, Heidi C. Hauffe, Jeremy B. Searle & Jacques Hausser
The aim of the present study was to investigate the genetic structure of the Valais shrew (Sorex antinorii) by a combined phylogeographical and landscape genetic approach, and thereby to infer the locations of glacial refugia and establish the influence of geographical barriers. We sequenced part of the mitochondrial cytochrome b (cyt b) gene of 179 individuals of S. antinorii sampled across the entire species' range. Six specimens attributed to S. arunchi were included in the...

Data from: Chronic malnutrition favours smaller critical size for metamorphosis initiation in Drosophila melanogaster

Roshan K. Vijendravarma, Sunitha Narasimha & Tadeusz J. Kawecki
Critical size at which metamorphosis is initiated represents an important checkpoint in insect development. Here we use experimental evolution in Drosophila melanogaster to test the long-standing hypothesis that larval malnutrition should favour a smaller critical size. We report that six fly populations subject to 112 generations of laboratory natural selection on an extremely poor larval evolved an 18 % smaller critical size (compared to six unselected control populations). Thus, even though critical size is not...

Data from: Plastic and evolutionary responses of cell size and number to larval malnutrition in Drosophila melanogaster

Roshan K Vijendravarma, Sunitha Narasimha & Tadeusz J Kawecki
Both development and evolution under chronic malnutrition lead to reduced adult size in Drosophila. We studied the contribution of changes in size vs. number of epidermal cells to plastic and evolutionary reduction of wing size in response to poor larval food. We used flies from six populations selected for tolerance to larval malnutrition and from six unselected control populations, raised either under standard conditions or under larval malnutrition. In the control populations, phenotypic plasticity of...

Data from: Reconstructing the origins of high-alpine niches and cushion life form in the genus Androsace s.l. (Primulaceae)

Florian Boucher, Wilfried Thuiller, Cristina Roquet, Rolland Douzet, Serge Aubert, Nadir Alvarez & Sébastien Lavergne
Relatively few species have been able to colonize extremely cold alpine environments. We investigate the role played by the cushion life form in the evolution of climatic niches in the plant genus Androsace s.l., which spreads across the mountain ranges of the Northern Hemisphere. Using robust methods that account for phylogenetic uncertainty, intraspecific variability of climatic requirements and different life history evolution scenarios, we show that climatic niches of Androsace s.l. exhibit low phylogenetic signal...

Data from: Ecology and life history affect different aspects of the population structure of 27 high-alpine plants

Patrick G. Meirmans, Jerome Goudet, IntraBioDiv Consortium & Oscar E. Gaggiotti
A plant species' genetic population structure is the result of a complex combination of its life history, ecological preferences, position in the ecosystem, and historical factors. As a result, many different statistical methods exist that measure different aspects of species’ genetic structure. However, little is known about how these methods are interrelated and how they are related to a species’ ecology and life history. In this study, we used the IntraBioDiv AFLP-dataset from 27 high-alpine...

Data from: Evidence for morphological and adaptive genetic divergence between lake and stream habitats in European minnows (Phoxinus phoxinus, Cyprinidae)

Hélène Collin & Luca Fumagalli
Natural selection drives local adaptation, potentially even at small temporal and spatial scales. As a result, adaptive genetic and phenotypic divergence can occur among populations living in different habitats. We investigated patterns of differentiation between contrasting lake and stream habitats in the cyprinid fish European minnow (Phoxinus phoxinus) at both the morphological and genomic level using geometric morphometrics and AFLP markers, respectively. We also used a spatial correlative approach to identify AFLP loci associated with...

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: Systematics of snow voles (Chionomys, Arvicolinae) revisited

Glenn Yannic, Reto Burri, Vladimir G. Malikov & Peter Vogel
To elucidate the evolutionary history of snow voles, genus Chionomys, we studied the phylogeography of Chionomys nivalis across its range and investigated its relationships with two congeneric species, C. gud and C. roberti, using independent molecular markers. Analyses were based on mitochondrial (~940 bp cyt b) and Y-chromosomal (~2020 bp from three introns) genetic variation. Our data provide conclusive evidence for a Caucasian and Middle Eastern origin for the three species and a subsequent westward...

Data from: Nonspecific PCR amplification by high-fidelity polymerases: implications for next-generation sequencing of AFLP markers.

Alan Brelsford, Hélène Collin, Nicolas Perrin & Luca Fumagalli
High-fidelity “proofreading” polymerases are often used in library construction for next-generation sequencing projects, in an effort to minimize errors in the resulting sequence data. The increased template fidelity of these polymerases can come at the cost of reduced template specificity, and library preparation methods based on the AFLP technique may be particularly susceptible. Here, we compare AFLP profiles generated with standard Taq and two versions of a high-fidelity polymerase. We find that Taq produces fewer...

Data from: Genetic components to caste allocation in a multiple-queen ant species

Romain Libbrecht, Tanja Schwander & Laurent Keller
Reproductive division of labor and the coexistence of distinct castes are hallmarks of insect societies. In social insect species with multiple queens per colony, the fitness of nestmate queens directly depends on the process of caste allocation (i.e., the relative investment in queen, sterile worker and male production). The aim of this study is to investigate the genetic components to the process of caste allocation in a multiple-queen ant species. We conducted controlled crosses in...
