Data from: Ontogenetic changes in genetic variances of age-dependent plasticity along a latitudinal gradient

Viktor Nilsson-Örtman, Bjorn Rogell, Robby Stoks & Frank Johansson
The expression of phenotypic plasticity may differ among life stages of the same organism. Age-dependent plasticity can be important for adaptation to heterogeneous environments, but this has only recently been recognized. Whether age-dependent plasticity is a common outcome of local adaptation and whether populations harbor genetic variation in this respect remains largely unknown. To answer these questions, we estimated levels of additive genetic variation in age-dependent plasticity in six species of damselflies sampled from 18...

Data from: AFLPs and mitochondrial haplotypes reveal local adaptation to extreme thermal environments in a freshwater gastropod

María Quintela, Magnus P. Johansson, Bjarni K. Kristjánsson, Rodolfo Barreiro & Anssi Laurila
The way environmental variation shapes neutral and adaptive genetic variation in natural populations is a key issue in evolutionary biology. Genome scans allow the identification of the genetic basis of local adaptation without previous knowledge of genetic variation or traits under selection. Candidate loci for divergent adaptation are expected to show higher FST than neutral loci influenced solely by random genetic drift, migration and mutation. The comparison of spatial patterns of neutral markers and loci...

Data from: Experimental evolution for generalists and specialists reveals multivariate genetic constraints on thermal reaction norms

David Berger, Richard J. Walters, Wolf U. Blanckenhorn, D. Berger, R. J. Walters & W. U. Blanckenhorn
Theory predicts the emergence of generalists in variable environments and antagonistic pleiotropy to favour specialists in constant environments, but empirical data seldom support such generalist–specialist trade-offs. We selected for generalists and specialists in the dung fly Sepsis punctum (Diptera: Sepsidae) under conditions that we predicted would reveal antagonistic pleiotropy and multivariate trade-offs underlying thermal reaction norms for juvenile development. We performed replicated laboratory evolution using four treatments: adaptation at a hot (31 °C) or a...

Data from: Reassessment of the non-titanosaurian somphospondylan Wintonotitan wattsi (Dinosauria: Sauropoda: Titanosauriformes) from the mid-Cretaceous Winton Formation, Queensland, Australia

Stephen F. Poropat, Philip D. Mannion, Paul Upchurch, Scott A. Hocknull, Benjamin P. Kear & David A. Elliott
Wintonotitan wattsi, a Cretaceous titanosauriform sauropod from central Queensland, Australia, is redescribed following a full revision of its osteology. The holotype specimen, a partial postcranial skeleton derived from the lower Upper Cretaceous Winton Formation, comprises axial and appendicular elements. Wintonotitan has been commonly resolved as a non-titanosaurian somphospondylan titanosauriform since its description, in contrast to its more derived contemporary Diamantinasaurus matildae. We provide a detailed redescription, taking this opportunity to correct four misinterpretations made in...

Data from: Flowering time QTL in natural populations of Arabidopsis thaliana and implications for their adaptive value

Emily L. Dittmar, Christopher G. Oakley, Jon Ågren & Douglas W. Schemske
The genetic basis of phenotypic traits is of great interest to evolutionary biologists, but their contribution to adaptation in nature is often unknown. To determine the genetic architecture of flowering time in ecologically relevant conditions, we used a recombinant inbred line population created from two locally adapted populations of Arabidopsis thaliana from Sweden and Italy. Using these RILs, we identified flowering time QTL in growth chambers that mimicked the natural temperature and photoperiod variation across...

Data from: Disentangling the contribution of sexual selection and ecology to the evolution of size dimorphism in pinnipeds

Oliver Krüger, Jochen B. W. Wolf, Rudy M. Jonker, Joseph I. Hoffman & Fritz Trillmich
The positive relationship between sexual size dimorphism (SSD) and harem size across pinnipeds is often cited as a textbook example of sexual selection. It assumes that female aggregation selected for large male size via male-male competition. Yet, it is also conceivable that SSD evolved prior to polygyny due to ecological forces. We analysed eleven life history traits in 35 pinniped species to determine their co-evolutionary dynamics and infer their most likely evolutionary trajectories contrasting these...

Antiviral, antibiotics and decongestants in wastewater treatment plants and receiving rivers in the Thames catchment

A.C. Singer, Järhult, R. Grabic, G.A. Khan, R.H. Lindberg, G. Fedorova, J. Fick, M.J. Bowes, B. Olsen & H. Söderström
This dataset contains the concentration of eleven antibiotics (trimethoprim, oxytetracycline, ciprofloxacin, azithromycin, cefotaxime, doxycycline, sulfamethoxazole, erythromycin, clarithromycin, ofloxacin, norfloxacin), three decongestants (naphazoline, oxymetazoline, xylometazoline) and the antiviral drug oseltamivir's active metabolite, oseltamivir carboxylate, measured at 21 locations within the River Thames catchment in England. The measurements were taken weekly during November 2009, once in March 2010 and once in May 2011, with the aim to quantify pharmaceutical usage during the influenza pandemic of 2009 and...

Data from: Worldwide patterns of ancestry, divergence, and admixture in domesticated cattle

Jared Egan Decker, Stephanie D. McKay, Megan M. Rolf, JaeWoo Kim, Antonio Molina Alcalá, Tad S. Sonstegard, Olivier Hanotte, Anders Götherström, Christopher M. Seabury, Lisa Praharani, Masroor Ellahi Babar, Luciana Correia De Almieda Regitano, Mehmet Ali Yildiz, Michael P. Heaton, Wan-Sheng Liu, Chu-Zhao Lei, James M. Reecy, Muhammad Saif-Ur-Rehman, Robert D. Schnabel, Jeremy F. Taylor, Jared E. Decker & Antonio Molina Alcalá
The domestication and development of cattle has considerably impacted human societies, but the histories of cattle breeds have been poorly understood especially for African, Asian, and American breeds. Using genotypes from 43,043 autosomal single nucleotide polymorphism markers scored in 1,543 animals, we evaluate the population structure of 134 domesticated bovid breeds. Regardless of the analytical method or sample subset, the three major groups of Asian indicine, Eurasian taurine, and African taurine were consistently observed. Patterns...

Data from: PCR-based isolation of multigene families: lessons from the avian MHC class IIB

Reto Burri, Marta Promerová, Julien Goebel & Luca Fumagalli
The amount of sequence data available today highly facilitates the access to genes from many gene families. Primers amplifying the desired genes over a range of species are readily obtained by aligning conserved gene regions, and laborious gene isolation procedures can often be replaced by quicker PCR-based approaches. However, in the case of multigene families, PCR-based approaches bear the often ignored risk of incomplete isolation of family members. This problem is most prominent in gene...

Data from: Transcriptome resources for the perennial sunflower Helianthus maximiliani obtained from ecologically divergent populations

Takeshi Kawakami, Brian J. Darby & Mark C. Ungerer
Next generation sequencing (NGS) technologies provide a rapid means to generate genomic resources for species exhibiting interesting ecological and evolutionary variation but for which such resources are scant or nonexistent. In the current report, we utilize 454 pyrosequencing to obtain transcriptome information for multiple individuals and tissue types from geographically disparate and ecologically differentiated populations of the perennial sunflower species Helianthus maximiliani. A total of 850,275 raw reads were obtained averaging 355 bp in length....

Data from: The role of pleiotropy and linkage in genes affecting a sexual ornament and bone allocation in the chicken

Martin Johnsson, Carl-Johan Rubin, Andrey Höglund, Anna-Stina Sahlqvist, Kenneth B. Jonsson, Susanne Kerje, Olov Ekwall, Olle Kämpe, Leif Andersson, Per Jensen & Dominic Wright
Sexual selection and the ornaments that inform such choices have been extensively studied, particularly from a phenotypic perspective. Although more is being revealed about the genetic architecture of sexual ornaments, much still remains to be discovered. The comb of the chicken is one of the most widely recognized sexual ornaments, which has been shown to be correlated with both fecundity and bone allocation. In this study we use a combination of multiple intercrosses between White...

Data from: Fine scale genetic correlates to condition and migration in a wild Cervid

Joseph M. Northrup, Aaron B. A. Shafer, , David W. Coltman, George Wittemyer & Charles R. Anderson
The relationship between genetic variation and phenotypic traits is fundamental to the study and management of natural populations. Such relationships often are investigated by assessing correlations between phenotypic traits and heterozygosity or genetic differentiation. Using an extensive data set compiled from free-ranging mule deer (Odocoileus hemionus), we combined genetic and ecological data to (i) examine correlations between genetic differentiation and migration timing, (ii) screen for mitochondrial haplotypes associated with migration timing, and (iii) test whether...

Data from: The influence of mitonuclear genetic variation on personality in seed beetles

Hanne Løvlie, Elina Immonen, Emil Gustavsson, Erem Kazancioğlu, Göran Arnqvist, H. Lovlie, G. Arnqvist, E. Gustavsson & E. Immonen
There is a growing awareness of the influence of mitochondrial genetic variation on life-history phenotypes, particularly via epistatic interactions with nuclear genes. Owing to their direct effect on traits such as metabolic and growth rates, mitonuclear interactions may also affect variation in behavioural types or personalities (i.e. behavioural variation that is consistent within individuals, but differs among individuals). However, this possibility is largely unexplored. We used mitonuclear introgression lines, where three mitochondrial genomes were introgressed...

Data from: Proxy comparison in ancient peat sediments: pollen, macrofossil and plant DNA

Laura Parducci, Minna Väliranta, J. Sakari Salonen, Tiina Ronkainen, Irina Matetovici, Sonia L. Fontana, Tiina Eskola, Pertti Sarala & Yoshihisa Suyama
We compared DNA, pollen and macrofossil data obtained from Weichselian interstadial and Holocene (maximum age 8400 cal yr BP) peat sediments from northern Europe and used them to reconstruct contemporary floristic compositions at two sites. The majority of the samples provided plant DNA sequences of good quality with success amplification rates depending on age. DNA and sequencing analysis provided five plant taxa from the older site and nine taxa from the younger site, corresponding to...

Data from: Female responses to experimental removal of sexual selection in Drosophila melanogaster

Paolo Innocenti, Ilona Flis & Edward H. Morrow
Background: Despite the common assumption that multiple mating should in general be favored in males, but not in females, to date there is no consensus on the general impact of multiple mating on female fitness. Notably, very little is known about the genetic and physiological features underlying the female response to sexual selection pressures. By combining an experimental evolution approach with genomic techniques, we investigated the effects of single and multiple matings on female fecundity...

Data from: Evaluating the postcopulatory sexual selection hypothesis for genital evolution reveals evidence for pleiotropic harm exerted by the male genital spines of Drosophila ananassae

Karl Grieshop, Michal Polack, K. Grieshop & M. Polak
The contemporary explanation for the rapid evolutionary diversification of animal genitalia is that such traits evolve by post-copulatory sexual selection. Here, we test the hypothesis that the male genital spines of Drosophila ananassae play an adaptive role in post-copulatory sexual selection. Whereas previous work on two Drosophila species shows that these spines function in precopulatory sexual selection to initiate genital coupling and promote male competitive copulation success, further research is needed to evaluate the potential...

Data from: QTL mapping of freezing tolerance: links to fitness and adaptive trade-offs

Christopher G. Oakley, Jon Ågren, Rachel A. Atchison & Douglas W. Schemske
Local adaptation, defined as higher fitness of local vs. non-local genotypes, is commonly identified in reciprocal transplant experiments. Reciprocally adapted populations display fitness trade-offs across environments, but little is known about the traits and genes underlying fitness trade-offs in reciprocally adapted populations. We investigated the genetic basis and adaptive significance of freezing tolerance using locally adapted populations of Arabidopsis thaliana from Italy and Sweden. Previous reciprocal transplant studies of these populations indicated that sub-freezing temperature...

Data from: Between-sex genetic covariance constrains the evolution of sexual dimorphism in Drosophila melanogaster

Fiona C. Ingleby, Paolo Innocenti, Howard D. Rundle, E. H. Morrow, H. D. Rundle, F. C. Ingleby & P. Innocenti
Males and females share much of their genome, and as a result, intralocus sexual conflict is generated when selection on a shared trait differs between the sexes. This conflict can be partially or entirely resolved via the evolution of sex-specific genetic variation that allows each sex to approach, or possibly achieve, its optimum phenotype, thereby generating sexual dimorphism. However, shared genetic variation between the sexes can impose constraints on the independent expression of a shared...

Data from: ModelOMatic: fast and automated comparison between RY, nucleotide, amino acid, and codon substitution models

Simon Whelan, James E. Allen, Benjamin P. Blackburne & David Talavera
Molecular phylogenetics is a powerful tool for inferring both the process and pattern of evolution from genomic sequence data. Statistical approaches, such as maximum likelihood and Bayesian inference, are now established as the preferred methods of inference. The choice of models that a researcher uses for inference is of critical importance, and there are established methods for model selection conditioned on a particular type of data, such as nucleotides, amino acids, or codons. A major...

Data from: Comparative support for the expensive tissue hypothesis: big brains are correlated with smaller gut and greater parental investment in Lake Tanganyika cichlids

Masahito Tsuboi, Arild Husby, Alexander Kotrschal, Alexander Hayward, Séverine Denise Büchel, Josefina Zidar, Hanne Løvlie & Niclas Kolm
The brain is one of the most energetically expensive organs in the vertebrate body. Consequently, the energetic requirements of encephalization are suggested to impose considerable constraints on brain size evolution. Three main hypotheses concerning how energetic constraints might affect brain evolution predict covariation between brain investment and i) investment into other costly tissues, ii) overall metabolic rate, and iii) reproductive investment. To date, these hypotheses have mainly been tested in homeothermic animals and the existing...

Data from: Natural selection in a post-glacial range expansion: the case of the colour cline in the European barn owl

Sylvain Antoniazza, Ricardo Kanitz, Samuel Neuenschwander, Reto Burri, Arnaud Gaigher, Alexandre Roulin & Jérôme Goudet
Gradients of variation – or clines – have always intrigued biologists. Classically, they have been interpreted as the outcomes of antagonistic interactions between selection and gene flow. Alternatively, clines may also establish neutrally with isolation-by-distance or secondary contact between previously isolated populations. The relative importance of natural selection and these two neutral processes in the establishment of clinal variation can be tested by comparing genetic differentiation at neutral genetic markers and at the studied trait....

Data from: Short term variation in sperm competition causes sperm mediated epigenetic effects on early offspring performance in the zebrafish

Susanne R. K. Zajitschek, Cosima Hotzy, Felix Zajitschek, Simone Immler, C. Hotzy & S. Immler
The inheritance of non-genetic factors is increasingly seen to play a major role in ecology and evolution. While the causes and consequences of epigenetic effects transmitted from the mother to the offspring have received ample attention, much less is known about how variation in the condition of the father affects the offspring. Here, we manipulated the intensity of sperm competition experienced by male zebrafish Danio rerio to investigate the potential for sperm-mediated epigenetic effects over...

Data from: Estimation of linkage disequilibrium and interspecific gene flow in Ficedula flycatchers by a newly developed 50k SNP array

Takeshi Kawakami, Niclas Backstrom, Reto Burri, Arild Husby, Pall Olason, Amber Rice, Murielle Alund, Anna Qvarnstrom, Hans Ellegren & Amber M. Rice
With the access to draft genome sequence assemblies and whole-genome re-sequencing data from population samples, molecular ecology studies will be able to take truly genome-wide approaches. This now applies to an avian model system in ecological and evolutionary research: Old World flycatchers of the genus Ficedula, for which we recently obtained a 1.1 Gb collared flycatcher genome assembly and identified 13 million SNPs in population re-sequencing of this species and its sister species, pied flycatcher....

Data from: Rates of dinosaur body mass evolution indicate 170 million years of sustained ecological innovation on the avian stem lineage

Roger B. J. Benson, Nicolás E. Campione, Matthew T. Carrano, Philip D. Mannion, Corwin Sullivan, Paul Upchurch & David C. Evans
Large-scale adaptive radiations might explain the runaway success of a minority of extant vertebrate clades. This hypothesis predicts, among other things, rapid rates of morphological evolution during the early history of major groups, as lineages invade disparate ecological niches. However, few studies of adaptive radiation have included deep time data, so the links between extant diversity and major extinct radiations are unclear. The intensively studied Mesozoic dinosaur record provides a model system for such investigation,...

Data from: Sperm competition generates evolution of increased paternal investment in a sex role-reversed seed beetle

Isobel Booksmythe, Karoline Fritzsche, Göran Arnqvist, I. Booksmythe, K. Fritzsche & G. Arnqvist
When males provide females with resources at mating they can become the limiting sex in reproduction, in extreme cases leading to the reversal of typical courtship roles. The evolution of male provisioning is thought to be driven by male reproductive competition and selection for female fecundity enhancement. We used experimental evolution under male- or female-biased sex ratios and limited or unlimited food regimes to investigate the relative roles of these routes to male provisioning in...
