Data from: Early arrival and climatically-linked geographic expansion of New World monkeys from tiny African ancestors

Daniele Silvestro, Marcelo F. Tejedor, Martha L. Serrano-Serrano, Oriane Loiseau, Victor Rossier, Jonathan Rolland, Alexander Zizka, Sebastian Höhna, Alexandre Antonelli & Nicolas Salamin
New World monkeys (platyrrhines) are one of the most diverse groups of primates, occupying today a wide range of ecosystems in the American tropics and exhibiting large variations in ecology, morphology, and behavior. Although the relationships among the almost 200 living species are relatively well understood, we lack robust estimates of the timing of origin, ancestral morphology, and geographic range evolution of the clade. Here we integrate paleontological and molecular evidence to assess the evolutionary...

Data from: Consumption of carotenoids not increased by bacterial infection in brown trout embryos (Salmo trutta)

Lucas Marques Da Cunha, Laetitia G.E. Wilkins, Laure Menin, Daniel Ortitz, Véronique Vocat-Mottier, Claus Wedekind & Laetitia G. E. Wilkins
Carotenoids are organic pigment molecules that play important roles in signalling, control of oxidative stress, and immunity. Fish allocate carotenoids to their eggs, which gives them the typical yellow to red colouration and supports their resistance against microbial infections. However, it is still unclear whether carotenoids act mainly as a shield against infection or are used up during the embryos' immune defence. We investigated this question with experimental families produced from wild-caught brown trout (Salmo...

Data from: Heterogeneity in local density allows a positive evolutionary relationship between self-fertilisation and dispersal

James Rodger, Pietro Landi, Cang Hui & James G. Rodger
Despite empirical evidence for a positive relationship between dispersal and self-fertilisation (selfing), theoretical work predicts that these traits should always be negatively correlated, and the Good Coloniser Syndrome of high dispersal and selfing (Cf. Baker’s Law) should not evolve. Critically, previous work assumes that adult density is spatiotemporally homogeneous, so selfing results in identical offspring production for all patches, eliminating the benefit of dispersal for escaping from local resource competition. We investigate the joint evolution...

Data from: Avian malaria and bird humoral immune response

Jessica Delhaye, Tania Jenkins, Olivier Glaizot & Philippe Christe
Background: Plasmodium parasites are known to impose fitness costs on their vertebrate hosts. Some of these costs are due to the activation of the immune response, which may divert resources away from self-maintenance. Plasmodium parasites may also immuno-deplete their hosts. Thus, infected individuals may be less able to mount an immune response to a new pathogen than uninfected ones. However, this has been poorly investigated. Methods: The effect of Plasmodium infection on bird humoral immune...

Data from: Evolutionary dynamics of specialisation in herbivorous stick insects

Chloé Larose, Sergio Rasmann & Tanja Schwander
Understanding the evolutionary dynamics underlying herbivorous insect mega-diversity requires investigating the ability of insects to shift and adapt to different host plants. Feeding experiments with nine related stick insect species revealed that insects retain the ability to use ancestral host plants after shifting to novel hosts, with host plant shifts generating fundamental feeding niche expansions. These expansions were however not accompanied by expansions of the realized feeding niches, as species on novel hosts are generally...

Data from: Phylogenomics and the evolution of hemipteroid insects

Kevin P. Johnson, Christopher H. Dietrich, Frank Friedrich, Rolf G. Beutel, Benjamin Wipfler, Ralph S. Peters, Julie M. Allen, Malte Petersen, Alexander Donath, Kimberly K. O. Walden, Alexey M. Kozlov, Lars Podsiadlowski, Christoph Mayer, Karen Meusemann, Alexandros Vasilikopoulos, Robert M. Waterhouse, Stephen L. Cameron, Christiane Weirauch, Daniel R. Swanson, Diana M. Percy, Nate B. Hardy, Irene Terry, Shanlin Liu, Xin Zhou, Bernhard Misof … & Kazunori Yoshizawa
Hemipteroid insects (Paraneoptera), with over 10% of all known insect diversity, are a major component of terrestrial and aquatic ecosystems. Previous phylogenetic analyses have not consistently resolved the relationships among major hemipteroid lineages. We provide maximum likelihood-based phylogenomic analyses of a taxonomically comprehensive dataset comprising sequences of 2,395 single-copy, protein-coding genes for 193 samples of hemipteroid insects and outgroups. These analyses yield a well-supported phylogeny for hemipteroid insects. Monophyly of each of the three hemipteroid...

Data from: Evolution of longevity improves immunity in Drosophila

Daniel K. Fabian, Kathrin Garschall, Peter Klepsatel, Gonçalo Santos-Matos, Élio Sucena, Martin Kapun, Bruno Lemaitre, Robert Arking, Christian Schloetterer & Thomas Flatt
Much has been learned about the genetics of aging from studies in model organisms, but still little is known about naturally occurring alleles that contribute to variation in longevity. For example, analysis of mutants and transgenes has identified insulin signaling as a major regulator of longevity, yet whether standing variation in this pathway underlies microevolutionary changes in lifespan and correlated fitness traits remains largely unclear. Here we have analyzed the genomes of a set of...

Data from: Dobzhansky-Muller incompatibilities, dominance drive, and sex-chromosome introgression at secondary contact zones: a simulation study

Luca Sciuchetti, Christophe Dufresnes, Elisa Cavoto, Alan Brelsford & Nicolas Perrin
Dobzhansky-Muller (DM) incompatibilities involving sex chromosomes have been proposed to account for Haldane’s rule (lowered fitness among hybrid offspring of the heterogametic sex) as well as Darwin’s corollary (asymmetric fitness costs with respect to the direction of the cross). We performed simulation studies of a hybrid zone to investigate the effects of different types of DM incompatibilities on cline widths and positions of sex-linked markers. From our simulations, X-Y incompatibilities generate steep clines for both...

Data from: The presence of kleptoparasitic fledglings is associated with a reduced breeding success in the host family in the barn owl

Motti Charter, Ido Izhaki & Alexandre Roulin
Fledgling birds sometimes abandon their own nest and move to neighboring nests where they are fed by host parents. This behaviour, referred to as “nest‐switching”, is well known in precocial birds that are mobile soon after hatching and can easily reach foster nests. In contrast, due to the difficulty of observing nest‐switching in territorial altricial birds, the causes and consequences of moving to others’ nests are poorly known in this group of birds. Nest‐switchers can...

Data from: Rapid seasonal evolution in innate immunity of wild Drosophila melanogaster

Emily L. Behrman, Virginia M. Howick, Martin Kapun, Fabian Staubach, Alan O. Bergland, Dmitri A. Petrov, Brian P. Lazzaro & Paul S. Schmidt
Understanding the rate of evolutionary change and the genetic architecture that facilitates rapid adaptation is a current challenge in evolutionary biology. Comparative studies show that genes with immune function are among the most rapidly evolving genes across a range of taxa. Here, we use immune defence in natural populations of Drosophila melanogaster to understand the rate of evolution in natural populations and the genetics underlying rapid change. We probed the immune system using the natural...

Data from: Profound genetic divergence and asymmetric parental genome contributions as hallmarks of hybrid speciation in polyploid toads

Caroline Betto-Colliard, Sylvia Hofmann, Roberto Sermier, Nicolas Perrin & Matthias Stöck
The evolutionary causes and consequences of allopolyploidization, an exceptional pathway to instant hybrid speciation, are poorly investigated in animals. In particular, when and why hybrid polyploids versus diploids are produced, and constraints on sources of paternal and maternal ancestors, remain underexplored. Using the Palearctic green toad radiation (including bisexually reproducing species of three ploidy levels) as model, we generate a range-wide multi-locus phylogeny of 15 taxa and present four new insights: (i) At least five...

Data from: An inversion supergene in Drosophila underpins latitudinal clines in survival traits

Esra Durmaz, Clare Benson, Martin Kapun, Paul Schmidt & Thomas Flatt
Chromosomal inversions often contribute to local adaptation across latitudinal clines, but the underlying selective mechanisms remain poorly understood. We and others have previously shown that a clinal inversion polymorphism in Drosophila melanogaster, In(3R)Payne, underpins body size clines along the North American and Australian east coasts. Here we ask whether this polymorphism also contributes to clinal variation in other fitness-related traits, namely survival traits (lifespan, survival upon starvation, and survival upon cold shock). We generated homokaryon...

Data from: Positive selection on sociobiological traits in invasive fire ants

Eyal Privman, Pnina Cohen, Amir B. Cohanim, Oksana Riba-Grognuz, DeWayne Shoemaker & Laurent Keller
The fire ant Solenopsis invicta and its close relatives are highly invasive. Enhanced social cooperation may facilitate invasiveness in these and other invasive ant species. We investigated whether invasiveness in Solenopsis fire ants was accompanied by positive selection on sociobiological traits by applying a phylogenomics approach to infer ancient selection, and a population genomics approach to infer recent and ongoing selection in both native and introduced S. invicta populations. A combination of whole-genome sequencing of...

Data from: Host diet mediates a negative relationship between abundance and diversity of Drosophila gut microbiota

Berra Erkosar, Erika Yashiro, Felix Zajitschek, Urban Friberg, Alexei A. Maklakov, Jan Roelof Van Der Meer & Tadeusz J. Kawecki
Nutrient supply to ecosystems has major effects on ecological diversity, but it is unclear to what degree the shape of this relationship is general versus dependent on the specific environment or community. Although the diet composition in terms of the source or proportions of different nutrient types is known to affect gut microbiota composition, the relationship between the quantity of nutrients supplied and the abundance and diversity of the intestinal microbial community remains to be...

Data from: Disentangling the processes driving plant assemblages in mountain grasslands across spatial scales and environmental gradients

Daniel Scherrer, Heidi K. Mod, Julien Pottier, Anne Dubuis-Litsios, Loïc Pellissier, Pascal Vittoz, Lars Götzenberger, Martin Zobel & Antoine Guisan
Habitat filtering and limiting similarity are well‐documented ecological assembly processes that hierarchically filter species across spatial scales, from a regional pool to local assemblages. However, information on the effects of fine‐scale spatial partitioning of species, working as an additional mechanism of coexistence, on community patterns is much scarcer. In this study, we quantified the importance of fine‐scale spatial partitioning, relative to habitat filtering and limiting similarity in structuring grassland communities in the western Swiss Alps....

Data from: A melanin-based trait is more strongly related to body size in the tropics than in temperate regions in the globally distributed barn owl family

Alexandre Roulin, Vera Uva & Andrea Romano
Life history traits differ between organisms living in the tropics, northern and southern hemispheres, and sexual selection is thought to be stronger close to the equator than in temperate regions. Although birds are often supposed to be more brightly coloured in the tropics, the current evidence of geographic variation in the intensity of sexual selection and sex-specific natural selection is equivocal. Whether sex-specific traits signal aspects of individual quality better in the tropics than in...

Data from: Species divergence and maintenance of species cohesion of three closely related Primula species in the Qinghai-Tibet Plateau

Guangpeng Ren, Rubén G. Mateo, Antoine Guisan, Elena Conti & Nicolas Salamin
Aim: Understanding the relative roles of geography and ecology in driving speciation, population divergence and maintenance of species cohesion is of great interest to molecular ecology. Closely related species that are parapatrically distributed in mountainous areas provide an ideal model to evaluate these key issues, especially when genomic data are analyzed within a spatially and ecologically explicit context. Here we used three closely related species of Primula that occur in the Himalayas, the Hengduan Mountains...

Data from: A dedicated target capture approach reveals variable genetic markers across micro- and macro-evolutionary time scales in palms

Marylaure De La Harpe, Jaqueline Hess, Oriane Loiseau, Nicolas Salamin, Christian Lexer & Margot Paris
Understanding the genetics of biological diversification across micro- and macro-evolutionary time scales is a vibrant field of research for molecular ecologists as rapid advances in sequencing technologies promise to overcome former limitations. In palms, an emblematic, economically and ecologically important plant family with high diversity in the tropics, studies of diversification at the population and species levels are still hampered by a lack of genomic markers suitable for the genotyping of large numbers of recently...

Data from: Selection for associative learning of color stimuli reveals correlated evolution of this learning ability across multiple stimuli and rewards.

Maartje Liefting, Katja M. Hoedjes, Cécile Le Lann, Hans M. Smid & Jacintha Ellers
We are only starting to understand how variation in cognitive ability can result from local adaptations to environmental conditions. A major question in this regard is to what extent selection on cognitive ability in a specific context affects that ability in general through correlated evolution. To address this question we performed artificial selection on visual associative learning in female Nasonia vitripennis wasps. Using appetitive conditioning in which a visual stimulus was offered in association with...

Data from: First draft genome of an iconic clownfish species (Amphiprion frenatus)

Anna Marcionetti, Victor Rossier, Joris A.M. Bertrand, Glenn Litsios, Nicolas Salamin & Joris A. M. Bertrand
Clownfishes (or anemonefishes) form an iconic group of coral reef fishes, principally known for their mutualistic interaction with sea anemones. They are characterized by particular life-history traits, such as a complex social structure and mating system involving sequential hermaphroditism, coupled with an exceptionally long lifespan. Additionally, clownfishes are considered to be one of the rare group to have experienced an adaptive radiation in the marine environment. Here, we assembled and annotated the first genome of...

Data from: Sex in the wild: how and why field-based studies contribute to solving the problem of sex

Maurine Neiman, Patrick Gerardus Meirmans, Tanja Schwander & Stephanie Meirmans
Why and how sexual reproduction is maintained in natural populations, the so-called “queen of problems”, is a key unanswered question in evolutionary biology. Recent efforts to solve the problem of sex have often emphasized results generated from laboratory settings. Here, we use a survey of representative “sex in the wild” literature to review and synthesize the outcomes of empirical studies focused on natural populations. Especially notable results included relatively strong support for mechanisms involving niche...

Data from: Parasitic versus nutritional regulation of natural fish populations

Amélie Frantz, Marie-Elodie Perga & Jean Guillard
1. Although parasites are expected to affect their host’s fitness, quantitative proof for impacts of parasitism on wild populations is hampered by confounding environmental factors, including dietary resource. 2. Herein, we evaluate whether the physiological conditions of European perch (Perca fluviatilis) in three large peri-alpine lakes (Geneva, Annecy, and Bourget) depend on (a) the nutritional status of the juvenile fish, as revealed by stable isotope and fatty acid compositions, (b) the prevalence of the tapeworm...

Data from: Sex chromosome turnovers and genetic drift: a simulation study

Paul A Saunders, Samuel Neuenschwander & Nicolas Perrin
The recent advances of new genomic technologies has enabled to identify and characterize sex chromosomes in an increasing number of non-model species, revealing that many plants and animals undergo frequent sex chromosome turnovers. What evolutionary forces drive these turnovers remains poorly understood, but it was recently proposed that drift might play a more important role than generally assumed. We analyzed the dynamics of different types of turnovers using individual-based simulations, and show that when mediated...

Data from: Protoporphyrin-based eggshell pigmentation is associated with female plumage colouration and predicts offspring sex ratio in the barn swallow

Margherita Corti, Andrea Romano, Alessandra Costanzo, Alexandra B. Bentz, Kristen Navara, Marco Parolini, Nicola Saino, Diego Rubolini & Kristen J. Navara
Inter- and intraspecific variation in eggshell colouration has long fascinated evolutionary biologists. Among species, such variation may accomplish different functions, the most obvious of which is camouflage and background matching. Within species, it has been proposed that inter-female variation in eggshell pigmentation patterns can reflect egg, maternal or paternal traits and hence may provide cues to conspecifics about egg, maternal or paternal phenotypic quality. However, the relationship between protoporphyrin-based eggshell pigmentation and egg or maternal/paternal...
