Data from: The legacy of Eastern Mediterranean mountain uplifts – rapid disparity of phylogenetic niche conservatism and divergence in mountain vipers

Mohsen Ahmadi, Mahmoud-Reza Hemami, Mohammad Kaboli, Masoud Nazarizadeh, Mansoureh Malekian, Roozbeh Behrooz, Philippe Geniez, John Alroy & Niklaus E. Zimmermann
Aim The orogeny of the eastern Mediterranean region has substantially affected ecological speciation patterns, particularly of mountain-dwelling species. Mountain vipers of the genus Montivipera are among the paramount examples of Mediterranean neo-endemism, with restricted ranges in the mountains of Anatolia, the Levant, Caucasus, Alborz, and Zagros. Here we explore the phylogenetic and ecological diversification of Montivipera to reconstruct its ecological niche evolution and biogeographic history. Location Eastern Mediterranean mountain ecosystems Methods Using 177 sequences of...

Consequences of population structure for sex allocation and sexual conflict

Leonor R Rodrigues, Mario Torralba Sáez, João Alpedrinha, Sophie Lefèvre, Muriel Brengues, Sara Magalhães & Alison Duncan
Both sex allocation and sexual conflict can be modulated by spatial structure. However, how the interplay between the type of dispersal and the scale of competition simultaneously affects these traits in sub-divided populations is rarely considered. We investigated sex allocation and sexual conflict evolution in meta-populations of the spider mite Tetranychus urticae evolving under budding (pairing females from the same patch) or random (pairing females from different patches) dispersal and either local (fixed sampling from...

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...

Data from: Detection of the elusive dwarf sperm whale (Kogia sima) using environmental DNA at Malpelo island (Eastern Pacific, Colombia)

Jean-Baptiste Juhel
Monitoring large marine mammals is challenging due to their low abundances in general, an ability to move over large distances and wide geographical range sizes. The distribution of the pygmy (Kogia breviceps) and dwarf (Kogia sima) sperm whales is informed by relatively rare sightings, which does not permit accurate estimates of their distribution ranges. Hence, their conservation status has long remained Data Deficient (DD) in the Red list of the International Union for Conservation of...

In silico and empirical evaluation of twelve metabarcoding primer sets for insectivorous diet analyses

Orianne Tournayre, Ondine Filippi-Codaccioni, Marine Trillat, Sylvain Piry, Dominique Pontier, Nathalie Charbonnel, Maxime Galan & Maxime Leuchtmann
During the most recent decade, environmental DNA metabarcoding approaches have been both developed and improved to minimize the biological and technical biases in these protocols. However, challenges remain, notably those relating to primer design. In the current study, we comprehensively assessed the performance of ten COI and two 16S primer pairs for eDNA metabarcoding, including novel and previously published primers. We used a combined approach of in silico, in vivo-mock community (33 arthropod taxa from...

Pre-introduction introgression contributes to parallel differentiation and contrasting hybridisation outcomes between invasive and native marine mussels

Iva Popovic, Nicolas Bierne, Federico Gaiti, Miloš Tanurdžić & Cynthia Riginos
Non-native species experience novel selection pressures in introduced environments and may interbreed with native lineages. Species introductions therefore provide opportunities to investigate repeated patterns of adaptation and introgression across replicated contact zones. Here, we investigate genetic parallelism between multiple introduced populations of the invasive marine mussel, Mytilus galloprovincialis, in the absence (South Africa and California) and presence of hybridisation with a native congener (Mytilus planulatus in Batemans Bay and Sydney Harbour, Australia). Repeatability in post-introduction...

The legacy of recurrent introgression during the radiation of hares

Mafalda S. Ferreira, Matthew R. Jones, Colin M. Callahan, Liliana Farelo, Zelalem Tolesa, Franz Suchentrunk, Pierre Boursot, L. Scott Mills, Paulo C. Alves, Jeffrey M. Good & José Melo-Ferreira
Hybridization may often be an important source of adaptive variation, but the extent and long-term impacts of introgression have seldom been evaluated in the phylogenetic context of a radiation. Hares (Lepus) represent a widespread mammalian radiation of 32 extant species characterized by striking ecological adaptations and recurrent admixture. To understand the relevance of introgressive hybridization during the diversification of Lepus, we analyzed whole exome sequences (61.7 Mb) from 15 species of hares (1- 4 individuals...

In situ resistance, not immigration, supports invertebrate community resilience to drought intensification in a Neotropical ecosystem

Camille Bonhomme, Régis Céréghino, Jean-François Carrias, Arthur Compin, Bruno Corbara, Vincent E.J. Jassey, Joséphine Leflaive, Vinicius F. Farjalla, Nicholas A. C. Marino, Thibaut Rota, Diane S. Srivastava & Céline Leroy
While future climate scenarios predict declines in precipitations in many regions of the world, little is known of the mechanisms underlying community resilience to prolonged dry seasons, especially in “naïve” Neotropical rainforests. Predictions of community resilience to intensifying drought are complicated by the fact that the underlying mechanisms are mediated by species’ tolerance and resistance traits, as well as rescue through dispersal from source patches. We examined the contribution of in situ tolerance-resistance and immigration...

Michael Abrouk, Hanin Ibrahim Ahmed, Philippe Cubry, Denisa Šimoníková, Stéphane Cauet, Yveline Pailles, Jan Bettgenhaeuser, Liubov Gapa, Nora Scarcelli, Marie Couderc, Leila Zekraoui, Nagarajan Kathiresan, Jana Čížková, Eva Hřibová, Jaroslav Doležel, Sandrine Arribat, Hélène Bergès, Jan Wieringa, Mathieu Gueye, Ndjido Kane, Christian Leclerc, Sandrine Causse, Sylvie Vancoppenolle, Claire Billot, Thomas Wicker … & Simon Krattinger
Sustainable food production in the context of climate change necessitates diversification of agriculture and a more efficient utilization of plant genetic resources. Fonio millet (Digitaria exilis) is an orphan African cereal crop with a great potential for dryland agriculture. Here, we established high-quality genomic resources to facilitate fonio improvement through molecular breeding. These include a chromosome-scale reference assembly and deep re-sequencing of 183 cultivated and wild Digitaria accessions, enabling insights into genetic diversity, population structure,...

Data from: Exceptional but vulnerable microbial diversity in coral reef animal surface microbiomes

Marlène Chiarello, Jean-Christophe Auguet, Nicholas Graham, Thomas Claverie, Elliott Sucré, Corinne Bouvier, Fabien Rieuvilleneuve, Claudia Restrepo-Ortiz, Yvan Bettarel, Sébastien Villéger & Thierry Bouvier
Coral reefs host hundreds of thousands of animal species that are increasingly threatened by anthropogenic disturbances. These animals host microbial communities at their surface, playing crucial roles for their fitness. However the diversity of such microbiomes is mostly described in a few coral species, and still poorly defined in other invertebrates and vertebrates. Given the diversity of animal microbiomes, and the diversity of host species inhabiting coral reefs, the contribution of such microbiomes to the...

Data from: Decomposition of leaf litter mixtures across biomes: The role of litter identity, diversity and soil fauna

Shixing Zhou, Olaf Butenschoen, Sandra Barantal, I. Tanya Handa, Marika Makkonen, Veronique Vos, Rien Aerts, Matty P. Berg, Brendan McKie, Jasper Van Ruijven, Stephan Hättenschwiler & Stefan Scheu
1. At broad spatial scales, the factors regulating litter decomposition remain ambiguous, with the understanding of these factors largely based on studies investigating site-specific single litter species, whereas studies using multi litter species mixtures across sites are rare. 2. We exposed in microcosms containing single species and all possible mixtures of four leaf litter species differing widely in initial chemical and physical characteristics from a temperate forest to the climatic conditions of four different forests...

French (F) and Swedish (S) Founder (P) and Mutation Accumulation Line (MA) performance in France and Sweden

Charles Fenster, Mao-Lun Weng, Jon Agren, Henning Nottebrock, Eric Imbert & Matthew Rutter
Little is empirically known about the contribution of mutations to fitness in natural environments. However, Fisher's Geometric Model (FGM) provides a conceptual foundation to consider the influence of the environment on mutational effects. To quantify mutational properties in the field, we established eight sets of MA lines (7-10 generations) derived from eight founders collected from natural populations of Arabidopsis thaliana from French and Swedish sites, representing the range margins of the species in Europe. We...

Data from: Sampling schemes and drift can bias admixture proportions inferred by STRUCTURE

Ken Toyama, Pierre-André Crochet & Raphaël Leblois
The interbreeding of individuals coming from genetically differentiated but incompletely isolated populations can lead to the formation of admixed populations, having important implications in ecology and evolution. In this simulation study, we evaluate how individual admixture proportions estimated by the software structure are quantitatively affected by different factors. Using various scenarios of admixture between two diverging populations, we found that unbalanced sampling from parental populations may seriously bias the inferred admixture proportions; moreover, proportionally large...

Data from: Sequential co-infections drive parasite competition and the outcome of infection

Giacomo Zilio & Jacob Koella
1) Co-infections by multiple parasites are common in natural populations. Some of these are likely to be the result of sequential rather than simultaneous infections. The timing of the co-infections may affect their competitive interactions, thereby influencing the success of the parasites and their impact on the host. This may have important consequence for epidemiological and eco-evolutionary dynamics. 2) We examined in two ecological conditions the effect of sequential co-infection on the outcome of infection...

Data from: Submerged macrophytes affect the temporal variability of aquatic ecosystems

Moritz Lürig, Rebecca Best, Vasilis Dakos & Blake Matthews
1. Submerged macrophytes are important foundation species that can strongly influence the structure and functioning of aquatic ecosystems, but only little is known about the temporal variation and the timescales of these effects (i.e. from hourly, daily, to monthly). 2. Here, we conducted an outdoor experiment in replicated mesocosms (1000 L) where we manipulated the presence and absence of macrophytes to investigate the temporal variability of their ecosystem effects. We measured several parameters (chlorophyll-a, phycocyanin,...

Data from: Daridorexant, a new dual orexin receptor antagonist in elderly subjects with insomnia disorder: a randomized clinical trial

Gary Zammit, Yves Dauvilliers, Scott Pain, Dalma Sebök Kinter, Yosef Mansour & Dieter Kunz
Objective: To assess the dose-response of daridorexant, a new dual orexin receptor antagonist, on wake after sleep onset (WASO). Methods: Elderly (≥65 years) subjects (n = 58) with insomnia were randomly allocated (Latin square design) to receive five treatments (5, 10, 25, and 50 mg daridorexant and placebo) during five treatment periods, each consisting of two treatment nights followed by a 5–12-day washout period. Main efficacy endpoints were the absolute change from baseline in WASO...

A genomics resource for genetics, physiology, and breeding of West African sorghum

Jacques Faye, Fanna Maina, Eyanawa Akata, Bassirou Sine, Cyril Diatta, Aissata Mamadou, Sandeep Marla, Sophie Bouchet, Niaba Teme, Jean-Francois Rami, Daniel Fonceka, Ndiaga Cisse & Geoffrey Morris
Local landrace and breeding germplasm is a useful source of genetic diversity for regional and global crop improvement initiatives. Sorghum (Sorghum bicolor L. Moench) in West Africa has diversified across a mosaic of cultures and end-uses, and along steep precipitation and photoperiod gradients. To facilitate germplasm utilization, a West African sorghum association panel (WASAP) of 756 accessions from national breeding programs of Niger, Mali, Senegal, and Togo was assembled and characterized. Genotyping-by-sequencing was used to...

Data from: Markov-modulated continuous-time Markov chains to identify site- and branch-specific evolutionary variation in BEAST

Guy Baele, Mandev Gill, Paul Bastide, Philippe Lemey & Marc Suchard
Markov models of character substitution on phylogenies form the foundation of phylogenetic inference frameworks. Early models made the simplifying assumption that the substitution process is homogeneous over time and across sites in the molecular sequence alignment. While standard practice adopts extensions that accommodate heterogeneity of substitution rates across sites, heterogeneity in the process over time in a site-specific manner remains frequently overlooked. This is problematic, as evolutionary processes that act at the molecular level are...

Drivers of longitudinal telomere dynamics in the long-lived bat species, Myotis myotis

Nicole Foley, Eric Petit, Thomas Brazier, John Finarelli, Graham Hughes, Frederic Touzalin, Sebastien Puechmaille & Emma Teeling
Age related telomere shortening is considered a hallmark of the ageing process. However, a recent cross-sectional ageing study of relative telomere length (rTL) in bats failed to detect a relationship between rTL and age in the long-lived genus Myotis (M. myotis and M. bechsteinii), suggesting some other factors are responsible for driving telomere dynamics in these species. Here, we test if longitudinal rTL data show signatures of age-associated telomere attrition in M. myotis and differentiate...

Data from: Endosymbiont diversity in natural populations of Tetranychus mites is rapidly lost under laboratory conditions

Flore Zélé, Inês Santos, Margarida Matos, Mylène Weill, Fabrice Vavre & Sara Magalhães
Although the diversity of bacterial endosymbionts in arthropods is well documented, whether and how such diversity is maintained remains an open question. We investigated the temporal changes occurring in the prevalence and composition of endosymbionts after transferring natural populations of Tetranychus spider-mites from the field to the laboratory. These populations, belonging to three different Tetranychus species (T. urticae, T. ludeni and T. evansi) carried variable infection frequencies of Wolbachia, Cardinium, and Rickettsia. We report a...

Age-dependent phenological plasticity in a wild bird

Suzanne Bonamour, Luis-Miguel Chevin, Denis Reale, Celine Teplitsky & Anne Charmantier
Life-history traits are often plastic in response to environmental factors such as temperature or precipitation, and they also vary with age in many species. Trait variation during the lifetime could thus be partly driven by age-dependent plasticity in these traits. We study whether plasticity of a phenological trait – the egg-laying date – with respect to spring temperature, varies with age, and explore whether this variation relates to changes in breeding success throughout the life...

The Geometry and Genetics of Hybridization

Hilde Schneemann, Bianca De Sanctis, Denis Roze, Nicolas Bierne & John Welch
When divergent populations form hybrids, hybrid fitness can vary with genome composition, current environmental conditions, and the divergence history of the populations. We develop analytical predictions for hybrid fitness, which incorporate all three factors. The predictions are based on Fisher's geometric model, and apply to a wide range of population genetic parameter regimes and divergence conditions, including allopatry and parapatry, local adaptation and drift. Results show that hybrid fitness can be decomposed into intrinsic effects...

Data from: Genomic evidence of prevalent hybridization throughout the evolutionary history of the fig-wasp pollination mutualism

Gang Wang, Xingtan Zhang, Edward Herre, Charles Cannon, Doyle McKey, Carlos Machado, Wen-Bin Yu, Michael Arnold, Rodrigo Pereira, Ray Ming, Yi-Fei Liu, Yibin Wang, Dongna Ma & Jin Chen
Ficus (figs) and their agaonid wasp pollinators present an ecologically important mutualism that also provides a rich comparative system for studying functional co-diversification throughout its coevolutionary history (~75 million years). We obtained entire nuclear, mitochondrial, and chloroplast genomes for 15 species representing all major clades of Ficus. Multiple analyses of these genomic data suggest that hybridization events have occurred throughout Ficus evolutionary history. Furthermore, cophylogenetic reconciliation analyses detect significant incongruence among all nuclear, chloroplast, and...

Temporally consistent species differences in parasite infection but no evidence for rapid parasite-mediated speciation in Lake Victoria cichlid fish

Tiziana P Gobbin, Maarten PM Vanhove, Antoine Pariselle, Ton GG Groothuis, Martine E Maan & Ole Seehausen
Parasites may have strong eco-evolutionary interactions with their hosts. Consequently, they may contribute to host diversification. The radiation of cichlid fish in Lake Victoria provides a good model to study the role of parasites in the early stages of speciation. We investigated patterns of macroparasite infection in a community of 17 sympatric cichlids from a recent radiation and 2 older species from 2 non-radiating lineages, to explore the opportunity for parasite-mediated speciation. Host species had...
