Data from: Effect of oceanographic barriers and overfishing on the population genetic structure of the European spiny lobster (Palinurus elephas)

Ferran Palero, Pere Abelló, Enrique Macpherson, Mark Beaumont & Marta Pascual
Defining population structure and genetic diversity levels is of the utmost importance for developing efficient conservation strategies. Overfishing has caused mean annual catches of the European spiny lobster (Palinurus elephas) to decrease alarmingly along its distribution area. In this context, there is a need for comprehensive studies to evaluate the genetic health of the exploited populations. The present work is based on a set of 10 nuclear markers amplified in 331 individuals from 10 different...

Data from: From global to local genetic structuring in the red gorgonian Paramuricea clavata: the interplay between oceanographic conditions and limited larval dispersal

Kenza Mokhtar-Jamaï, Marta Pascual, Jean-Baptiste Ledoux, Rafel Coma, Jean-Pierre Féral, Joaquim Garrabou & Didier Aurelle
Defining the scale of connectivity among marine populations and identifying the barriers to gene flow are tasks of fundamental importance for understanding the genetic structure of populations and for the design of marine reserves. Here we investigated the population genetic structure at three spatial scales of the red gorgonian Paramuricea clavata (Cnidaria, Octocorallia) a key species dwelling in the coralligenous assemblages of the Mediterranean Sea. Colonies of P. clavata were collected from 39 locations across...

Data from: Candidate genes for colour and vision exhibit signals of selection across the pied flycatcher (Ficedula hypoleuca) breeding range

Paula K. Lehtonen, Toni Laaksonen, Aleksandr V. Artemyev, Eugen Belskii, Paul R. Berg, Christiaan Both, Laura Buggiotti, Stanislav Bureš, Malcolm D. Burgess, Andrey V. Bushuev, Indrikis Krams, Juan Moreno, Marko Mägi, Andreas Nord, Jaime Potti, Pierre-Alain Ravussin, Glenn Peter Sætre, Paivi Sirkiä, Wolfgang Winkel & Craig R. Primmer
The role of natural selection in shaping adaptive trait differentiation in natural populations has long been recognized. Determining its molecular basis, however, remains a challenge. Here, we search for signals of selection in candidate genes for colour and its perception in a passerine bird. Pied flycatcher plumage varies geographically in both its structural and pigment-based properties. Both characteristics appear to be shaped by selection. A single-locus outlier test revealed two of fourteen loci to exhibit...

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: Matching genetics with oceanography: directional gene flow in a Mediterranean fish species

Celia Schunter, Josep Carreras-Carbonell, Enrique Macpherson, Joaquin Tintoré, Enrique Vidal-Vijande, Ananda Pascual, Paolo Guidetti & Marta Pascual
Genetic connectivity and geographic fragmentation are two opposing mechanisms determining the population structure of species. While the first homogenizes the genetic background across populations the second one allows their differentiation. Therefore, knowledge of processes affecting dispersal of marine organisms is crucial to understand their genetic distribution patterns and for the effective management of their populations. In this study, we use genetic analyses of eleven microsatellites in combination with oceanographic satellite and dispersal simulation data to...

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: Is sociality required for the evolution of communicative complexity? Evidence weighed against alternative hypotheses in diverse taxonomic groups

Terry J. Ord & Joan Garcia-Porta
Complex social communication is expected to evolve whenever animals engage in many and varied social interactions; that is, sociality should promote communicative complexity. Yet informal comparisons among phylogenetically independent taxonomic groups seem to cast doubt on the putative role of social factors in the evolution of complex communication. Here, we provide a formal test of the sociality hypothesis along side alternative explanations for the evolution of communicative complexity. We compiled data documenting variation in signal...

Data from: Phylogenetic ecology of widespread uncultured clades of the Kingdom Euryarchaeota

Albert Barberán, Antoni Fernández-Guerra, Jean-Christophe Auguet, Pierre E Galand & Emilio O Casamayor
Despite its widespread distribution and high levels of phylogenetic diversity, microbes are poorly understood creatures. We applied a phylogenetic ecology approach in the Kingdom Euryarchaeota (Archaea) to gain insight into the environmental distribution and evolutionary history of one of the most ubiquitous and largely unknown microbial groups. We compiled 16S rRNA gene sequences from our own sequence libraries and public genetic databases for two of the most widespread mesophilic Euryarchaeota clades, Lake Dagow Sediment (LDS)...

Data from: Major histocompatability complex variation in insular populations of the Egyptian vulture: inferences about the roles of genetic drift and selection

Rosa Agudo, Miguel Alcaide, Ciro Rico, Jesus Angel Lemus, Guillermo Blanco, Fernando Hiraldo & Jose Antonio Donázar
Insular populations have attracted the attention of evolutionary biologists because of their morphological and ecological peculiarities with respect to their mainland counterparts. Founder effects and genetic drift are known to distribute neutral genetic variability in these demes. However, elucidating whether these evolutionary forces have also shaped adaptive variation is crucial to evaluate the real impact of reduced genetic variation in small populations. Genes of the Major Histocompatibility Complex (MHC) are classical examples of evolutionarily relevant...

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: Temporal variation in genetic diversity and effective population size of Mediterranean and subalpine Arabidopsis thaliana populations

Nasr H. Gomaa, Alicia Montesinos-Navarro, Carlos Alonso-Blanco & F. Xavier Picó
Currently there exists a limited knowledge on the extent of temporal variation in population genetic parameters of natural populations. Here we study the extent of temporal variation in population genetics by genotyping 151 genome-wide SNP markers polymorphic in 466 individuals collected from nine populations of the annual plant Arabidopsis thaliana during four years. Populations are located along an altitudinal climatic gradient from Mediterranean to subalpine environments in NE Spain, which has been shown to influence...
