Data from: Genetic, morphological and acoustic evidence reveals lack of diversification in the colonization process in an island bird

Juan Carlos Illera, Ana M. Palmero, Paola Laiolo, Felipe Rodríguez, Ángel C. Moreno & Miguel Navascués
Songbirds with recently (i.e. early Holocene) founded populations are suitable models for studying incipient differentiation in oceanic islands. On such systems each colonization event represents a different evolutionary episode that can be studied by addressing sets of diverging phenotypic and genetic traits. We investigate the process of early differentiation in the spectacled warbler (Sylvia conspicillata) in 14 populations separated by sea barriers from three Atlantic archipelagos and from continental regions spanning from tropical to temperate...

Data from: Morphometric analysis and taxonomic revision of Anisopteromalus Ruschka (Hymenoptera: Chalcidoidea: Pteromalidae) – an integrative approach

Hannes Baur, Yvonne Kranz-Baltensperger, Astrid Cruaud, Jean-Yves Rasplus, Alexander V. Timokhov & Vladimir E. Gokhman
We use an integrative taxonomic approach to revise the genus Anisopteromalus. In particular, we apply multivariate ratio analysis (MRA), a rather new statistical method based on principal component analysis (PCA) and linear discriminant analysis (LDA), to numerous body measurements and combine the data with those from our molecular analysis of Cytb and ITS2 genetic markers (on a subset of species) and all available published data on morphology, karyology, behavior, host associations, and geographic distribution. We...

Data from: Host-parasite network structure is associated with community-level immunogenetic diversity

Shai Pilosof, Miguel A. Fortuna, Jean-François Cosson, Maxime Galan, Chaisiri Kittipong, Alexis Ribas, Eran Segal, Boris R. Krasnov, Serge Morand & Jordi Bascompte
Genes of the major histocompatibility complex (MHC) encode proteins that recognize foreign antigens and are thus crucial for immune response. In a population of a single host species, parasite-mediated selection drives MHC allelic diversity. However, in a community-wide context, species interactions may modulate selection regimes because the prevalence of a given parasite in a given host may depend on its prevalence in other hosts. By combining network analysis with immunogenetics, we show that host species...

Data from: Contrasted invasion processes imprint the genetic structure of an invasive scale insect across southern Europe

Carole Kerdelhué, Thomas Boivin & Christian Burban
Deciphering the colonization processes by which introduced pests invade new areas is essential to limit the risk of further expansion and/or multiple introductions. We here studied the invasion history of the maritime pine bast scale Matsucoccus feytaudi. This host-specific insect does not cause any damage in its native area, but it devastated maritime pine forests of South-Eastern France where it was detected in the 1960s, and since then reached Italy and Corsica. We used population...

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: Congruent signals of population history but radically different patterns of genetic diversity between mitochondrial and nuclear markers in a mountain lizard

Anne-Laure Ferchaud, Rémy Eudeline, Véronique Arnal, Marc Cheylan, Gilles Pottier, Raphaël Leblois & Pierre-Andre Crochet
Historical factors, current population size, population connectivity and selective processes at linked loci contribute to shaping contemporary patterns of neutral genetic diversity. It is now widely acknowledged that nuclear and mitochondrial markers react differently to current demography as well as to past history, so the use of both types of markers is often advocated to gain insight on both historical and contemporary processes. We used 12 microsatellite loci genotyped in 13 populations of a mountain...

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: Blacktip reef sharks, Carcharhinus melanopterus, have high genetic structure and varying demographic histories in their Indo-Pacific range

Thomas M. Vignaud, Johann Mourier, Jeffrey A. Maynard, Raphael Leblois, Julia L. Y. Spaet, Eric Clua, Valentina Neglia, Serge Planes & Julia L.Y. Spaet
For free-swimming marine species like sharks, only population genetics and demographic history analyses can be used to assess population health/status as baseline population numbers are usually unknown. We investigated the population genetics of blacktip reef sharks, Carcharhinus melanopterus; one of the most abundant reef-associated sharks and the apex predator of many shallow water reefs of the Indian and Pacific Oceans. Our sampling includes 4 widely separated locations in the Indo-Pacific and 11 islands in French...

Data from: Short-term variations in gene flow related to cyclic density fluctuations in the common vole

Bertrand Gauffre, Karine Berthier, Pablo Inchausti, Yannick Chaval, Jean-François Cosson & Vincent Bretagnolle
In highly fluctuating populations with complex social systems genetic patterns are likely to vary in space and time due to demographic and behavioural processes. Cyclic rodents are extreme examples of demographically instable populations that often exhibit strong social organisation. In such populations, kin structure and spacing behaviour may vary with density fluctuations and impact both the composition and spatial structure of genetic diversity. In this study, we analysed the multiannual genetic structure of a cyclic...

Data from: Genetic structure and hybridization in the species group of Ficus auriculata: can closely related sympatric Ficus species retain their genetic identity while sharing pollinators?

Zuo-Dong Wei, Noppol Kobmoo, Astrid Cruaud, Finn Kjellberg & Z.-D. Wei
Obligate mutualistic nursery pollination systems between insects and plants have led to substantial co-diversification involving at least some parallel cladogenesis, as documented in Yucca, Ficus and Phyllanthaceae. In such systems pollinators are generally species specific thus limiting hybridization and introgression among interfertile host species. Nevertheless, in the three systems, cases of one insect pollinating several plant species are reported. In most cases host plants sharing pollinators are allopatric. However in the case of the species...
