Data from: Phylogenetic relationships of Trachylepis skink species from Madagascar and the Seychelles (Squamata: Scincidae)

Alexandra Lima, David James Harris, Sara Rocha, Aurélien Miralles, Frank Glaw & Miguel Vences
Lizards of the genus Trachylepis are a species-rich group of skinks mainly inhabiting Africa, Madagascar, and several other islands in the western Indian Ocean. All except one probably introduced species of Madagascan Trachylepis are endemic. Two species groups have been distinguished on the basis of subocular scale shape but their phylogenetic relationships remained unclear. We inferred a multilocus phylogeny of the Madagascan Trachylepis species, based on a concatenated dataset of 3261 bp from 3 mitochondrial...

Data from: Towards a functional understanding of species coexistence: ecomorphological variation in relation to whole-organism performance in two sympatric lizards

Anamarija Žagar, Miguel A. Carretero, Al Vrezec, Katarina Drašler & Antigoni Kaliontzopoulou
1. We examined intra- and interspecific variation in functional morphology and whole-organism performance in a sympatric lizard species pair, Iberolacerta horvathi and Podarcis muralis, in the area with a high potential for competition. 2. The biggest variation between species was found in two functional traits, bite force and climbing speed, linked with corresponding morphological traits. 3. The species with larger and taller heads, P. muralis, exhibited correspondingly stronger bite forces. The other species exhibited smaller...

Data from: Genetic evidence for multiple events of hybridization between wolves and domestic dogs in the Iberian Peninsula

Raquel Godinho, Luís Llaneza, Juan Carlos Blanco, Susana Lopes, Francisco Álvares, Emilio J. García, Vicente Palacios, Yolanda Cortés, Javier Talegón & Nuno Ferrand
Hybridization between wild species and their domestic counterparts may represent a major threat to natural populations. However, high genetic similarity between the hybridizing taxa makes the detection of hybrids a difficult task and may hinder attempts to assess the impact of hybridization in conservation biology. In this work, we used a combination of 42 autosomal microsatellites together with Y-chromosome microsatellite-defined haplotypes and mtDNA sequences to investigate the occurrence and dynamics of wolf–dog hybridization in the...

Data from: The allometry of sound frequency bandwidth in songbirds

Jakob Isager Friis, Joana Sabino, Pedro Santos, Torben Dabelsteen & Goncalo C. Cardoso
Theory predicts that allometric constraints on sound production should be stronger for the lower frequencies of vocalizations than for their higher frequencies, which could originate an allometry for sound frequency bandwidth, but this was never tested. Using song recordings of ca. 1000 passerine species (from >75% passerine genera), we show a significantly steeper allometry for the lower than the higher song frequencies, resulting in a positive allometry of frequency bandwidth: larger species can use wider...

Genome-wide markers redeem the lost identity of a heavily managed gamebird

Qian Tang, Giovanni Forcina, Qian Tang, Emilie Cros, Monica Guerrini, Frank Rheindt & Filippo Barbanera
Heavily managed wildlife may suffer from genetic homogenisation and reshuffling of locally adapted genotypes with non-native ones. This phenomenon often affects natural populations by reducing their evolutionary potential and speeding up the ongoing biodiversity crisis. For decades, the red-legged partridge (Alectoris rufa), an intensively managed gamebird of conservation concern and considerable socio-economic importance, has been subjected to extensive releases of farm-reared hybrids with the chukar partridge (A. chukar) and translocations irrespective of subspecific affinity. These...

Bat phylogenetic responses to regenerating Amazonian forests

Fábio Z. Farneda, Ricardo Rocha, Sabhrina Gita Aninta, Adrià López-Baucells, Erica M. Sampaio, Jorge M. Palmeirim, Paulo E. D. Bobrowiec, Cristian S. Dambros & Christoph F. J. Meyer
1. Throughout the tropics, regenerating secondary forests occupy vast areas previously cleared for agriculture and cattle ranching. However, despite the importance of regenerating forests in mitigating the pervasive negative consequences of forest loss and fragmentation on forest-associated biodiversity, longitudinal studies on species’ phylogenetic responses to matrix regeneration are rare. 2. We surveyed bats in continuous primary forest, primary forest fragments and in the regenerating secondary forest matrix of a whole-ecosystem Amazonian fragmentation experiment, ~15 and...

Data from: Interpreting the genomic landscape of speciation: a road map for finding barriers to gene flow

Mark Ravinet, Rui Faria, Roger K. Butlin, Juan Galindo, Nicolas Bierne, Marina Rafajlović, Mohamed A. F. Noor, Bernhard Mehlig & Anja M. Westram
Speciation, the evolution of reproductive isolation amongst populations, is continuous, complex, and involves multiple, interacting barriers. Until it is complete, the effects of this process vary along the genome and can lead to a heterogeneous genomic landscape with peaks and troughs of differentiation and divergence. When gene flow occurs during speciation, barriers restricting migration locally in the genome lead to patterns of heterogeneity. However, genomic heterogeneity can also be produced or modified by variation in...

Data from: Range expansion underlies historical introgressive hybridization in the Iberian hare

João P. Marques, Liliana Farelo, Joana Vilela, Dan Vanderpool, Paulo C. Alves, Jeffrey M. Good, Pierre Boursot & José Melo-Ferreira
Introgressive hybridization is an important and widespread evolutionary process, but the relative roles of neutral demography and natural selection in promoting massive introgression are difficult to assess and an important matter of debate. Hares from the Iberian Peninsula provide an appropriate system to study this question. In its northern range, the Iberian hare, Lepus granatensis, shows a northwards gradient of increasing mitochondrial DNA (mtDNA) introgression from the arctic/boreal L. timidus, which it presumably replaced after...

Data from: Phylogenetic patterns of geographical and ecological diversification in the subgenus Drosophila

Ramiro Morales-Hojas & Jorge Vieira
Colonisation of new geographic regions and/or of new ecological resources can result in rapid species diversification into the new ecological niches available. Members of the subgenus Drosophila are distributed across the globe and show a large diversity of ecological niches. Furthermore, taxonomic classification of Drosophila includes the rank radiation, which refers to closely related species groups. Nevertheless, it has never been tested if these taxonomic radiations correspond to evolutionary radiations. Here we present a study...

Data from: A metabolic syndrome in terrestrial ectotherms with different elevational and distribution patterns

Anamarija Žagar, Miguel A. Carretero, Diana Marguč, Tatjana Simčič & Al Vrezec
The metabolic performance of ectotherms is expected to be driven by the environment in which they live. Ecologically similar species with contrasting elevation distributions occurring in sympatry at mid-elevations, provide good models for studying how physiological responses to temperature vary as a function of adaptation to different elevations.. Under sympatry, at middle elevations, where divergent species ranges overlap, sympatric populations are expected to have similar thermal responses, suggesting similar local acclimation or adaptation, while observed...

Data from: Antagonistic effect of helpers on breeding male and female survival in a cooperatively breeding bird

Matthieu Paquet, Claire Doutrelant, Ben J. Hatchwell, Claire N. Spottiswoode & Rita Covas
1. Cooperatively breeding species are typically long lived and hence, according to theory, are expected to maximize their lifetime reproductive success through maximizing survival. Under these circumstances, the presence of helpers could be used to lighten the effort of current reproduction for parents to achieve higher survival. 2. In addition, individuals of different sexes and ages may follow different strategies, but whether male and female breeders and individuals of different ages benefit differently from the...

Data from: \"Identification and assessment of single nucleotide polymorphisms (SNPs) between Culex complex mosquitoes.\" in Genomic Resources Notes Accepted 1 August 2014-30 September 2014

David S. Kang & Cheolho Sim
Culex pipiens complex mosquitoes are important vectors for many human pathogens including West Nile encephalitis, Rift Valley fever and Lymphatic filariasis. In this study we characterized a set of SNP markers between two biotypes of the Culex pipiens complex, Culex pipiens form molestus and Culex pipiens form pipiens, for use in a high-resolution genetic mapping and population genetics. DNA pooled from 10 specimens of each biotype were sequenced and analyzed for variation in 28 genes....

Data from: Heat tolerance is more variable than cold tolerance across species of Iberian lizards after controlling for intraspecific variation

Salvador Herrando-Pérez, Camila Monasterio, Wouter Beukema, Verónica Gomes, Francisco Gomes Ferri-Yáñez, Josabel Belliure, Steven L. Chown, Lauren B Buckley, David R. Vieites & Miguel B. Araújo
The widespread observation that heat tolerance is less variable than cold tolerance (‘cold-tolerance asymmetry’) leads to the prediction that species exposed to temperatures near their thermal maxima should have reduced evolutionary potential for adapting to climate warming. However, the prediction is largely supported by species-level global studies based on single estimates of both physiological metrics per taxon. We ask if cold-tolerance asymmetry holds for Iberian lizards after accounting for intraspecific variation in critical thermal maxima...

Data from: Phylogeography of the small Indian civet and origin of introductions to western Indian Ocean islands

Philippe Gaubert, Riddhi Patel, Geraldine Veron, Steve M. Goodman, Maraike Willsch, Raquel Vasconcelos, Andre Lourenço, Marie Sigaud, Fabienne Justy, Bheem Dutt Joshi, Joerns Fickel & Abdreas Wilting
The biogeographic dynamics affecting the Indian subcontinent, East and Southeast Asia during the Plio-Pleistocene has generated complex biodiversity patterns. We assessed the molecular biogeography of the small Indian civet (Viverricula indica) through mitogenome and cytochrome b + control region sequencing of 89 historical and modern samples to (i) establish a time-calibrated phylogeography across the species’ native range and (ii) test introduction scenarios to western Indian Ocean islands. Bayesian phylogenetic analyses identified three geographic lineages (East...

Data from: The lek mating system of the worm pipefish (Nerophis lumbriciformis): a molecular maternity analysis and test of the phenotype-linked fertility hypothesis

Nuno M. Monteiro, Diana Carneiro, Agostinho Antunes, Nuno Queiroz, Maria N. Vieira & Adam G. Jones
The origin and maintenance of mating preferences continues to be an important and controversial topic in sexual selection research. Leks and lek-like mating systems, where individuals gather in particular spots for the sole purpose of mate choice, are particularly puzzling, because the strong directional selection imposed by mate choice should erode genetic variation among competing individuals and negate any benefit for the choosing sex. Here, we take advantage of the lek-like mating system of the...

Data from: Bushmeat genetics: setting up a reference framework for the DNA-typing of African forest bushmeat

Philippe Gaubert, Flobert Njiokou, Ayodeji Olayemi, Paolo Pagani, Sylvain Dufour, Emmanuel Danquah, Mac Elikem K. Nutsuakor, Gabriel Ngua, Alain-Didier Missoup, Pablo A. Tedesco, Rémy Dernat & Agostinho Antunes
The bushmeat trade in tropical Africa represents illegal, unsustainable off-takes of millions of tons of wild game – mostly mammals – per year. We sequenced four mitochondrial gene fragments (cyt b, COI, 12S, 16S) in >300 bushmeat items representing nine mammalian orders and 59 morphological species from five western and central African countries (Guinea, Ghana, Nigeria, Cameroon and Equatorial Guinea). Our objectives were to assess the efficiency of cross-species PCR amplification and to evaluate the...

Data from: Dopamine disruption increases cleanerfish cooperative investment in novel client partners

Marta C. Soares, Teresa P. Santos & João P.M. Messias
Social familiarization is a process of gaining knowledge that results from direct or indirect participation in social events. Cooperative exchanges are thought to be conditional upon familiarity with others. Indeed, individuals seem to prefer to engage with those that have previously interacted with them, which are more accurate predictors of reward than novel partners. On the other hand, highly social animals do seek novelty. Truth is that the physiological bases underlying how familiarity and novelty...

Data from: Postglacial range expansion shaped the spatial genetic structure in a marine habitat-forming species: implications for conservation plans in the Eastern Adriatic Sea

Jean-Baptiste Ledoux, Maša Frleta-Valić, Silvija Kipson, Agostinho Antunes, Emma Cebrian, Cristina Linares, Pablo Sánchez, Raphael Leblois & Joaquim Garrabou
Aim: Understanding how historical and contemporary processes shaped and maintain spatial patterns of genetic diversity is a major goal for conservation biologists. Here, we characterized the pattern of neutral genetic diversity and we inferred underlying processes in the habitat-forming octocoral Paramuricea clavata in the Adriatic Sea, a peculiar phylogeographic region of the Mediterranean Sea. Location: Eastern coast of the Adriatic Sea. Methods: We genotyped seven microsatellites in 454 individuals of P. clavata from 13 populations...

Phenotypic divergence in two sibling species of shorebird: Common Snipe and Wilson's Snipe (Charadriiformes: Scolopacidae)

Tiago M Rodrigues, Edward Miller, Sergei V Drovetski, Robert M Zink, Jon Fjeldså & David Gonçalves
Natural selection and social selection are among the main shapers of biological diversity, but their relative importance in divergence remains understudied. Additionally, although neutral evolutionary processes may promote phenotypic divergence, their potential contribution in speciation is often overlooked in studies of comparative morphology. In this study, we investigated phenotypic differentiation in two allopatric shorebirds: the Palearctic Common Snipe Gallinago gallinago and the Nearctic Wilson’s Snipe G. delicata. Specimens of Common Snipe (n = 355 skins,...

Data from: Current climate, but also long-term climate changes and human impacts, determine the geographic distribution of European mammal diversity

Ana Margarida Coelho Dos Santos, Marcus Cianciaruso, A. Marcia Barbosa, Luis Mauricio Bini, José Alexandre Diniz-Filho, Frederico Augusto Faleiro, Sidney Gouveia, Rafael Loyola, Nagore Medina, Thiago Rangel, Geiziane Tessarolo & Joaquín Hortal
Aim. Historical climate variations, current climate and human impacts are known to influence current species richness, but their effects on phylogenetic and trait diversity have been seldom studied. We investigated the relationship of these three factors with the independent variations of species, phylogenetic and trait diversity of European mammals. Considering the position of the 0ºC isotherm in the Last Glacial Maximum as a tipping point, we tested the following hypotheses: northern European assemblages host less...

Data from: Fine-scale genetic structure reflects sex-specific dispersal strategies in a population of sociable weavers (Philetairus socius)

René E. Van Dijk, Rita Covas, Claire Doutrelant, Claire N. Spottiswoode & Ben J. Hatchwell
Dispersal is a critical driver of gene flow, with important consequences for population genetic structure, social interactions and other biological processes. Limited dispersal may result in kin-structured populations in which kin selection may operate, but it may also increase the risk of kin competition and inbreeding. Here, we use a combination of long-term field data and molecular genetics to examine dispersal patterns and their consequences for the population genetics of a highly social bird, the...
