Data from: De novo transcriptome assembly and polymorphism detection in two highly divergent evolutionary units of Bosca's newt (Lissotriton boscai) endemic to the Iberian Peninsula

Coralie Nourisson, Antonio Muñoz-Merida, Miguel Carneiro & Fernando Sequeira
This article reports the de novo transcriptomes of two highly divergent evolutionary units of the Iberian endemic Bosca’s newt, Lissotriton boscai. These two units are distributed allopatrically but meet in areas of secondary contact in central-southwestern coastal region of Portugal. The resources we provide include the raw sequence reads, the assembled transcripts and SNPs called for both lineages.

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: 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: 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: Signalling with a cryptic trait: the regularity of barred plumage in common waxbills

Cristiana I. J. Marques, Helena R. Batalha & Gonçalo C. Cardoso
Sexual signals often compromise camouflage, because of their conspicuousness. Pigmentation patterns, on the contrary, aid in camouflage. It was hypothesized that a particular type of pattern — barred plumage in birds, whereby pigmented bars extend across feathers — could simultaneously signal individual quality, because disruptions of these patterns should be perceptually salient at close range and help assess plumage condition. Here we show that common waxbills (Estrilda astrild), which have extensive barred plumage, have more...

Data from: Endemic species may have complex histories: within-refugium phylogeography of an endangered Iberian vole

Soraia Barbosa, Joana Paupério, Jeremy S. Herman, Clara M. Ferreira, Ricardo Pita, Hélia M. Vale-Gonçalves, João A. Cabral, José A. Garrido-García, Ramón C. Soriguer, Pedro Beja, António Mira, Paulo C. Alves & Jeremy B. Searle
Glacial refugia protected and promoted biodiversity during the Pleistocene, not only at a broader scale, but also for many endemics that contracted and expanded their ranges within refugial areas. Understanding the evolutionary history of refugial endemics is especially important in the case of endangered species to recognise the origins of their genetic structure and thus produce better informed conservation practices. The Iberian Peninsula is an important European glacial refugium, rich in endemics of conservation concern,...

Adam H. Freedman, Ilan Gronau, Rena M. Schweizer, Diego Ortega-Del Vecchyo, Eunjung Han, Pedro M. Silva, Marco Galaverni, Zhenxin Fan, Peter Marx, Belen Lorente-Galdos, Holly Beale, Oscar Ramirez, Farhad Hormozdiari, Can Alkan, Carles Vilà, Kevin Squire, Eli Geffen, Josip Kusak, Adam R. Boyko, Heidi G. Parker, Clarence Lee, Vasisht Tadigotla, Adam Siepel, Carlos D. Bustamante, Timothy T. Harkins … & John Novembre
To identify genetic changes underlying dog domestication and reconstruct their early evolutionary history, we generated high-quality genome sequences from three gray wolves, one from each of the three putative centers of dog domestication, two basal dog lineages (Basenji and Dingo) and a golden jackal as an outgroup. Analysis of these sequences supports a demographic model in which dogs and wolves diverged through a dynamic process involving population bottlenecks in both lineages and post-divergence gene flow....

Data from: Extended dispersal kernels in a changing world: insights from statistics of extremes

Cristina Garcia & Luís Borda-De-Água
Dispersal ecology is a topical discipline that involves understanding and predicting plant community responses to multiple drivers of global change. Propagule movements that entail long-distance dispersal (LDD) events are crucial for plants to reach and colonize suitable sites across fragmented landscapes. Yet, LDD events are extremely rare, and thus, obtaining reliable estimates of the maximum distances that propagules move across and of their frequency has been a long-lasting challenge in plant ecology. Recent advances in...

Data from: Maternal allocation in eggs when counting on helpers in a cooperatively breeding bird

Juliana Valencia, Concha Mateos, Carlos De La Cruz & Juan Carranza
For cooperatively breeding birds, it has been proposed that breeders should reduce their investment in eggs when they count on helpers, because this can be compensated for by helpers provisioning of nestlings. Data from some species have supported this prediction, but this is not the case in others. It has also been proposed that mothers should not reduce but rather increase investment if the presence of helpers enhances the reproductive value of offspring, a pattern...

Data from: Postnatal dynamics of developmental stability and canalization of lizard head shape under different environmental conditions

Marko M. Lazić, Miguel A. Carretero, Jelka Crnobrnja-Isailović & Antigoni Kaliontzopoulou
Developmental stability (DS) and canalization are key determinants of phenotypic variation. To provide a better understanding of how postnatal growth is involved in determining the effects of DS and canalization on phenotypic variation, we studied within- and among-individual variation in head shape in ontogenetic series of lizards inhabiting urban and rural environments. Urban lizards exhibited increased fluctuating asymmetry during the early postnatal stages, but asymmetry levels decreased during growth. By contrast, asymmetry remained constant across...

Data from: Experimental contact zones reveal causes and targets of sexual selection in hybridizing lizards

Hannah E. A. MacGregor, Geoffrey M. While, Jade Barrett, Guillem Pérez I De Lanuza, Pau Carazo, Sozos Michaelides & Tobias Uller
Divergence in sexually selected traits in allopatry should affect the degree and direction of hybridization. However, few studies have established the causes and targets of sexual selection during secondary contact. Common wall lizards (Podarcis muralis) from north-central Italy have highly exaggerated male sexual traits compared to populations in Western Europe. Using experimental populations, we show that this creates asymmetries in male dominance, spatial habitat use and reproductive success upon secondary contact. Hybridization occurred almost exclusively...

Data from: Genetic basis for red coloration in birds

Ricardo J Lopes, James D Johnson, Matthew B Toomey, Mafalda S Ferreira, Pedro M Araújo, José Melo-Ferreira, Leif Andersson, Geoffrey E Hill, Joseph C Corbo & Miguel Carneiro
The yellow and red feather pigmentation of many bird species [1] plays pivotal roles in social signaling and mate choice [2, 3]. To produce red pigments, birds ingest yellow carotenoids and endogenously convert them into red ketocarotenoids via an oxidation reaction catalyzed by a previously unknown ketolase [4–6]. We investigated the genetic basis for red coloration in birds using whole-genome sequencing of red siskins (Spinus cucullata), common canaries (Serinus canaria), and ‘‘red factor’’ canaries, which...

Data from: Female dietary bias towards large migratory moths in the European free-tailed bat (Tadarida teniotis)

Vanessa A. Mata, Francisco Amorim, Martin F. V. Corley, Gary F. McCracken, Hugo Rebelo & Pedro Beja
In bats, sexual segregation has been described in relation to differential use of roosting and foraging habitats. It is possible that variation may also exist between genders in the use of different prey types. However, until recently this idea was difficult to test owing to poorly resolved taxonomy of dietary studies. Here, we use high-throughput sequencing to describe gender-related variation in diet composition of the European free-tailed bat (Tadarida teniotis), while controlling for effects of...

Data from: Stable isotopes reveal differences in diet among reed bunting subspecies that vary in bill size

Júlio Manuel Neto, Luís De Oliveira Gordinho, Benjamin Vollot, Marcial Marín, Juan S. Monrós & Jason Newton
Reed bunting (Emberiza schoeniclus) subspecies vary considerably in bill size and shape and seem to be at an early stage of speciation, in which bill might be indirectly causing reproductive isolation. Hence, we evaluated whether bill size, as well as age and sex, are associated with foraging niche in three West European subspecies of reed bunting: the thin-billed schoeniclus, the intermediate-billed lusitanica and the thick-billed witherbyi. Blood sampling was undertaken at three sites in southwest...

Data from: The evolution of colour pattern complexity: selection for conspicuousness favours contrasting within-body colour combinations in lizards

Guillem Pérez I De Lanuza & Enrique Font
Many animals display complex colour patterns that comprise several adjacent, often contrasting colour patches. Combining patches of complementary colours increases the overall conspicuousness of the complex pattern, enhancing signal detection. Therefore, selection for conspicuousness may act not only on the design of single colour patches, but also on their combination. Contrasting long- and short-wavelength colour patches are located on the ventral and lateral surfaces of many lacertid lizards. As the combination of long- and short-wavelength-based...
