Data from: DNA metabarcoding unveils multi‐scale trophic variation in a widespread coastal opportunist

Andjin Siegenthaler, Owen S. Wangensteen, Chiara Benvenuto, Joana Campos & Stefano Mariani
A thorough understanding of ecological networks relies on comprehensive information on trophic relationships among species. Since unpicking the diet of many organisms is unattainable using traditional morphology‐based approaches, the application of high‐throughput sequencing methods represents a rapid and powerful way forward. Here, we assessed the application of DNA‐metabarcoding with nearly universal primers for the mitochondrial marker cytochrome c oxidase I (COI) in defining the trophic ecology of adult brown shrimp, Crangon crangon, in six European...

Data from: White shark genome reveals ancient elasmobranch adaptations associated with wound healing and the maintenance of genome stability

Nicholas J. Marra, Michael J. Stanhope, Nathaniel K. Jue, Minghui Wang, Qi Sun, Paulina P. Bitar, Vincent P. Richards, Aleksey Komissarov, Mike Rayko, Sergey Kliver, Bryce J. Stanhope, Chuck Winkler, Stephen J. O'Brien, Agostinho Antunes, Salvador J. Jorgensen & Mahmood S. Shivji
The white shark (Carcharodon carcharias; Chondrichthyes, Elasmobranchii) is one of the most publicly recognized marine animals. Here we report the genome sequence of the white shark and comparative evolutionary genomic analyses to the chondrichthyans, whale shark (Elasmobranchii) and elephant shark (Holocephali), as well as various vertebrates. The 4.63-Gbp white shark genome contains 24,520 predicted genes, and has a repeat content of 58.5%. We provide evidence for a history of positive selection and gene-content enrichments regarding...

Data from: Limited refugia and high velocity range-shifts predicted for bat communities in drought-risk areas of the Northern Hemisphere

Rachel Blakey, Mattia Piccioli Cappelli, Daniel Taylor, Jon Flanders, Trish Badeen, Sally Butts, Winifred Frick & Hugo Rebelo
Species occupying semi-arid and dry regions around the globe face an uncertain future due to increases in the frequency and severity of droughts. In this study we modelled the potential effect of climate change on bat communities within two high-drought risk regions of the world and assessed the magnitude and direction of the predicted shifts in climatic suitability, locating climate change refugia and identifying species at greatest risk of population declines. To do this, we...

Intense nocturnal warming alters growth strategies, coloration, and parasite load in a diurnal lizard

Alexis Rutschmann, Andréaz Dupoué, Donald Miles, Rodrigo Megía-Palma, Clémence Lauden, Murielle Richard, Arnaud Badiane, David Rozen-Rechels, Mathieu Brevet, Pauline Blaimont, Sandrine Meylan, Jean Clobert & Jean-François Le Galliard
1. In the past decades, nocturnal temperatures have been playing a disproportionate role in the global warming of the planet. Yet, they remain a neglected factor in studies assessing the impact of global warming on natural populations. In ectotherms, physiological performance is influenced by thermal conditions and an increase in body temperature of a few degrees during night-time is sufficient to induce a disproportionate increase in metabolic expenditure. 2. Here, we question whether an intense...

Data from: Global patterns of functional trait variation along aridity gradients in bats

Irene Conenna, Luca Santini, Ricardo Rocha, Ara Monadjem, Mar Cabeza & Danilo Russo
Aim: Our understanding of the biological strategies employed by species to cope with challenges posed by aridity is still limited. Despite being sensitive to water loss, bats successfully inhabit a wide range of arid lands. We here investigated how functional traits of bat assemblages vary along the global aridity gradient to identify traits that favour their persistence in arid environments. Methods: We mapped the assemblage-level averages of four key bat traits describing wing morphology, echolocation...

Don’t judge a lizard by its colour: no evidence for differential socio-sexual behaviour and space use in the colour morphs of the European common wall lizard (Podarcis muralis)

Javier Abalos, Guillem Pérez I De Lanuza, Alicia Bartolomé, Océane Liehrmann, Hanna Laakkonen, Fabien Aubret, Tobias Uller, Pau Carazo & Enrique Font
Explaining the evolutionary origin and maintenance of colour polymorphisms is a major challenge in evolutionary biology. Such polymorphisms are commonly thought to reflect the existence of alternative behavioural or life-history strategies under negative frequency-dependent selection. The European common wall lizard Podarcis muralis exhibits a striking ventral colour polymorphism that has been intensely studied and is often assumed to reflect alternative reproductive strategies, similar to the iconic “rock-paper-scissors” system described in the North American lizard Uta...

Data from: Network structure and the optimisation of proximity-based association criteria

Ana Cristina Gomes, Neeltje Boogert & Gonçalo Cardoso
Animal social network analysis (SNA) often uses proximity data obtained from automated tracking of individuals. Identifying associations based on proximity requires deciding on quantitative criteria such as the maximum distance or the longest time interval between visits of different individuals to still consider them associated. These quantitative criteria are not easily chosen based on a priori biological arguments alone. Here we propose a procedure for optimising proximity-based association criteria in SNA, whereby different spatial and...

SNP datasets obtained with ddRADseq from four contact zones between Podarcis carbonelli and four other Podarcis species

Guilherme Caeiro-Dias, Alan Brelsford, Antigoni Kaliontzopoulou, Mariana Meneses-Ribeiro, Pierre-André Chrochet & Catarina Pinho
We used double digestion restriction site associated DNA (ddRAD) sequencing to discover SNPs in samples from four contact zones between Podarcis carbonelli and four other Podarcis species. We obtained a panel of SNPs for each for each contact zone and reference populations and a dataset of diagnostic SNPs between reference populations for each contact zone but excluding private alleles from references, i.e. excluding alleles that are not present in the populations of contact. The final...

Collective foraging: Experimentally-increased competition decreases group performance exploiting a permanent resource

Patrícia Beltrão, Ana Cristina R Gomes & Gonçalo C Cardoso
Foraging collectively offers advantages, such as access to social information on food locations, but it may also intensify competition for local resources. Social information may be most advantageous during ecologically challenging conditions, when food sources are scarce or unpredictable, which predicts more collective foraging during such conditions. Alternatively, higher within-group competition when resources are scarce might destabilize social groups and reduce collective foraging. To evaluate these effects, we experimentally decreased the number and predictability of...

Data for influence of avocado orchard landscapes on amphibians and reptiles in the trans-Mexican volcanic belt

Ireri Suazo-Ortuño, Ismaela Vega-Agavo, Leonel Lopez-Toledo, Neftali Sillero, Alberto Gómez-Tagle, Ruben Pineda-López & Javier Alvarado-Díaz
This database was used to evaluate the response of the local herpetofauna to conversion of POF to avocado orchards (AO) in the trans-Mexican volcanic belt in Western Mexico (Michoacán state). We also explored the effects of forest cover on species that differ in their levels of habitat specialization. In the avocado belt in Michoacan, we sampled 12 sites representing a gradient of AO embedded in native POF to evaluate the variation in structure of local...

Environmental data from: Potential distributions of invasive vertebrates in the Iberian Peninsula under projected changes in climate extreme events

Rocío A. Baquero, A. Márcia Barbosa, Daniel Ayllón, Carlos Guerra, Enrique Sánchez, Miguel B. Araújo & Graciela G. Nicola
This dataset includes climatic variables representing extreme events indices defined by the World Meteorological Organization (https://public.wmo.int/en). The variables were calculated based on five Regional Climate Models or RCMs (UAHE-REM, UCAN-WRA, UCAN-WRB, UCLM-PRO and UMUR-MM5) for the periods 1971-2000 (‘current climate’) and 2021-2050 (‘future climate’) under the SRES A1B Emissions Scenario. We used RCMs instead of global climate models (GCMs) because the latter have an overly coarse resolution compared to the spatial resolution of our species...

Data from: Multiple quantitative trait loci influence intra-specific variation in genital morphology between phylogenetically distinct lines of Drosophila montana

Martin A Schäfer, Jarkko Routtu, Jorge Vieira, Anneli Hoikkala, Mike G Ritchie & Christian Schlötterer
The evolution of animal genitalia has gained renewed interest, because of their potential roles during sexual selection and early stages of species formation. Although central to understanding the evolutionary process, knowledge of the genetic basis of natural variation in genital morphology is limited to a very few species. Using an out-bred cross between phylogenetically distinct lines of Drosophila montana, we characterized quantitative trait loci (QTLs) affecting the size and shape of the distiphallus, a prominent...

Data from: Two distinct genomic regions, harbouring the period and fruitless genes, affect male courtship song in Drosophila montana

Malgorzata Lagisz, Shuo-Yang Wen, Jarkko Routtu, Kirsten Klappert, Dominique Mazzi, Ramiro Morales-Hojas, Jorge Vieira, Anneli Hoikkala, Michael G. Ritchie, Roger K. Butlin, Martin A Schäfer, J Routtu, D Mazzi, A Hoikkala, M Lagisz, S-Y Wen, R K Butlin, K Klappert, M G Ritchie, R Morales-Hojas & J Vieira
Acoustic signals often play a significant role in pair formation and in species recognition. Determining the genetic basis of signal divergence will help to understand signal evolution by sexual selection and its role in the speciation process. An earlier study investigated QTL for male courtship song carrier frequency in Drosophila montana using microsatellite markers. We refined this study by adding to the linkage map markers for ten candidate genes known to affect song production in...

Data from: Interploidal hybridization and mating patterns in the Sphagnum subsecundum complex

Mariana Ricca, P. Szövényi, Matthew G Johnson, A Jonathan Shaw & Eva M. Temsch
Polyploidization is thought to result in instant sympatric speciation, but several cases of hybrid zones between one of the parental species and its polyploid derivative have been documented. Previous work showed that diploid Sphagnum lescurii is an allopolyploid derived from the haploids S. lescurii (maternal progenitor) and S. subsecundum (paternal progenitor). Here we report the results from analyses of a population where allodiploid and haploid S. lescurii co-occur and produce sporophytes. We tested (1) whether...

Data from: Citizen science reveals unexpected continental-scale evolutionary change in a model organism

Jonathan Silvertown, Laurence Cook, Robert Cameron, Mike Dodd, Kevin McConway, Jenny Worthington, Peter Skelton, Christian Anton, Oliver Bossdorf, Bruno Baur, Menno Schilthuizen, Benoît Fontaine, Helmut Sattmann, Giorgio Bertorelle, Maria Correia, Cristina Oliveira, Beata Pokryszko, Małgorzata Ożgo, Arturs Stalažs, Eoin Gill, Üllar Rammul, Péter Sólymos, Zoltan Féher & Xavier Juan
Organisms provide some of the most sensitive indicators of climate change and evolutionary responses are becoming apparent in species with short generation times. Large datasets on genetic polymorphism that can provide an historical benchmark against which to test for recent evolutionary responses are very rare, but an exception is found in the brown-lipped banded snail (Cepaea nemoralis). This species is sensitive to its thermal environment and exhibits several polymorphisms of shell colour and banding pattern...

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...
