Data from: High-protein paternal diet confers an advantage to sons in sperm competition

Felix Zajitschek, Susanne Zajitschek & Mollie Manier
Parental environment can widely influence offspring phenotype, but paternal effects in the absence of parental care remain poorly understood. We asked if protein content in the larval diet of fathers affected paternity success and gene expression in their sons. We found that males reared on high-protein diet had sons that fared better during sperm competition, suggesting that postcopulatory sexual selection is subject to transgenerational paternal effects. Moreover, immune response genes were downregulated in sons of...

Data from: Haploid selection within a single ejaculate increases offspring fitness

Ghazal Alavioon, Cosima Hotzy, Khriezhanuo Nakhro, Sandra Rudolf, Douglas Scofield, Susanne Zajitschek, Alexei Maklakov & Simone Immler
An inescapable consequence of sex in eukaryotes is the evolution of a biphasic life cycle with alternating diploid and haploid phases. The occurrence of selection during the haploid phase can have far-reaching consequences for fundamental evolutionary processes including the rate of adaptation, the extent of inbreeding depression, and the load of deleterious mutations, as well as for applied research into fertilization technology. Although haploid selection is well established in plants, current dogma assumes that in...

Data from: The influence of habitat accessibility on the dietary and morphological specialisation of an aquatic predator

Maria H.K. Marklund, Richard Svanbäck, Yinghua Zha, Kristin Scharnweber, Peter Eklov & Maria H. K. Marklund
Individual diet and habitat specialisation are widespread in animal taxa and often related to levels of predation and competition. Mobile consumers such as predatory fish can stabilise lake food webs by ranging over a larger area than their prey, thereby switching between habitats. Although, this switching assumes that the predator has equal preference for the available prey, individual diet specialisation and morphological adaptations to different habitats could potentially prevent individuals from switching between habitats. In...

Data from: Subtle but ubiquitous selection on body size in a natural population of collared flycatchers over 33 years

Mats Björklund & Lars Gustafsson
Understanding the magnitude and long-term patterns of selection in natural populations is of importance, for example, when analyzing the evolutionary impact of climate change. We estimated univariate and multivariate directional, quadratic and correlational selection on four morphological traits (adult wing, tarsus and tail length, body mass) over a time period of 33 years (≈ 19 000 observations) in a nest-box breeding population of collared flycatchers (Ficedula albicollis). In general, selection was weak in both males...

Data from: Widespread increases in iron concentration in European and North American freshwaters

Caroline Björnerås, Gesa A. Weyhenmeyer, Chris D. Evans, Mark O. Gessner, Hans-Peter Grossart, Külli Kangur, Ilga Kokorite, Pirkko Kortelainen, Hjalmar Laudon, Jouni Lehoranta, Noah Lottig, Don T. Monteith, Peter Nõges, Tiina Nõges, Filip Oulehle, Gunnhild Riise, James A. Rusak, Antti Räike, Janis Sire, Shannon Sterling & Emma Kritzberg
Recent reports of increasing iron (Fe) concentrations in freshwaters are of concern, given the fundamental role of Fe in biogeochemical processes. Still, little is known about the frequency and geographical distribution of Fe trends, or about the underlying drivers. We analyzed temporal trends of Fe concentrations across 340 water bodies distributed over 10 countries in northern Europe and North America in order to gain a clearer understanding of where, to what extent, and why Fe...

Data from: Northeast African genomic variation shaped by the continuity of indigenous groups and Eurasian migrations

Nina Hollfelder, Carina M. Schlebusch, Torsten Günther, Hiba Babiker, Hisham Y. Hassan & Mattias Jakobsson
Northeast Africa has a long history of human habitation, with fossil-finds from the earliest anatomically modern humans, and housing ancient civilizations. The region is also the gate-way out of Africa, as well as a portal for migration into Africa from Eurasia via the Middle East and the Arabian Peninsula. We investigate the population history of northeast Africa by genotyping ~3.9 million SNPs in 221 individuals from 18 populations sampled in Sudan and South Sudan and...

Data from: Blood transcriptomes and de novo identification of candidate loci for mating success in lekking great snipe (Gallinago media)

Jacob Höglund, Biao Wang, Stein Are Saether, Mozes Pil Kyu Blom, Peder Fiske, Peter Halvarsson, Gavin J. Horsburgh, Terry Burke, John Atle Kålås & Robert Ekblom
We assembled the great snipe blood transcriptome using data from fourteen lekking males, in order to de novo identify candidate genes related to sexual selection, and determined the expression profiles in relation to mating success. The three most highly transcribed genes were encoding different haemoglobin subunits. All tended to be overexpressed in males with high mating success. We also called Single Nucleotide Polymorphisms (SNPs) from the transcriptome data and found considerable genetic variation for many...

Data from: Century-long tree population dynamics in a deciduous forest stand in central Sweden

Håkan Hytteborn, Brita M. Svensson, Kerstin Kempe, Andreas Press & Håkan Rydin
Question: We quantify tree dynamics over a century of free development in a small broadleaved forest dominated by Fraxinus excelsior and Ulmus glabra. What are the internal and external factors driving the changes, and how predictable are they? What were the time scale and effects of the spread of Dutch elm disease (DED)? Location: Vårdsätra, eastern central Sweden. Methods: The survival, growth and recruitment of all trees (≥ 12 cm in girth) were monitored in...

Data from: The earliest bird-line archosaurs and the assembly of the dinosaur body plan

Sterling J. Nesbitt, Richard J. Butler, Martin D. Ezcurra, Paul M. Barrett, Michelle R. Stocker, Kenneth D. Angielczyk, Roger M. H. Smith, Christian A. Sidor, Grzegorz Niedźwiedzki, Andrey G. Sennikov & Alan J. Charig
The relationship between dinosaurs and other reptiles is well established, but the sequence of acquisition of dinosaurian features has been obscured by the scarcity of fossils with transitional morphologies. The closest extinct relatives of dinosaurs either have highly derived morphologies or are known from poorly preserved or incomplete material. Here we describe one of the stratigraphically lowest and phylogenetically earliest members of the avian stem lineage (Avemetatarsalia), Teleocrater rhadinus gen. et sp. nov., from the...

Data from: The evolutionary origin of variation in song length and frequency in the avian family Cettiidae

Chentao Wei, Trevor D. Price, Jiayu Liu, Per Alström & Yanyun Zhang
Aspects of bird song have been shown to correlate with morphological and ecological features, including beak and body size, and habitat. Here we study evolution of song length and song frequency among 30 species belonging to the Cettiidae. Frequency is negatively correlated with body size, and song length increases with latitude. Although migration distance correlates with latitude, the association of song length with latitude is only present within the non-migratory species, implying the association is...

Data from: Ecology, biofacies, biogeography and systematics of micromorphic lingulate brachiopods from the Ordovician (Darriwilian–Sandbian) of south-central China

Lars E. Holmer, Mansoureh Ghobadi Pour, Leonid E. Popov, Zhiliang Zhang & Zhifei Zhang
Ordovician (Darriwilian to Sandbian) micromorphic linguliform lingulate brachiopods are described from the Guniutan Formation at the Fenxiang section in Hubei province, and the Maocaopu and Cili sections in Hunan province of south-central China, situated on the Yangtze Platform. A total of 7560 specimens from 155 limestone samples (within the interval of Lenodus variabilis – Pygodus anserinus biozones) are assigned to 22 species, representing a low taxonomic diversity and low abundance fauna. The fauna is dominated...

Data from: A worldwide phylogeography of the whiteworm lichen Thamnolia vermicularis reveals three lineages with distinct habitats and evolutionary histories

Ioana Onuţ-Brännström, Leif Tibell & Hanna Johannesson
Thamnolia is a lichenized fungus with an extremely wide distribution, being encountered in arctic and alpine environments in most continents. In this study, we used molecular markers to investigate the population structure of the fungal symbiont and the associated photosynthetic partner of Thamnolia. By analyzing molecular, morphological, and chemical variation among 253 specimens covering the species distribution range, we revealed the existence of three mycobiont lineages. One lineage (Lineage A) is confined to the tundra...

Data from: Male-benefit sexually antagonistic genotypes show elevated vulnerability to inbreeding

Karl Grieshop, David Berger & Göran Arnqvist
Background: There is theoretical and empirical evidence for strong sexual selection in males having positive effects on population viability by serving to purify the genome of its mutation load at a low demographic cost. However, there is also theoretical and empirical evidence for negative effects of sexual selection on female fitness, and therefore population viability, known as the gender load. This can take the form of sexually antagonistic (SA) genetic variation where alleles with a...

Data from: Ranking and characterization of established BMI and lipid associated loci as candidates for gene-environment interactions

Dmitry Shungin, Wei Q. Deng, Tibor V. Varga, Jian'an Luan, Evelin Mihailov, Andres Metspalu, Andrew P. Morris, Nita G. Forouhi, Cecilia Lindgren, Patrik K. E. Magnusson, Nancy L. Pedersen, Göran Hallmans, Audrey Y. Chu, Anne E. Justice, Mariaelisa Graff, Thomas W. Winkler, Lynda M. Rose, Claudia Langenberg, L. Adrienne Cupples, Paul M. Ridker, Nicholas J. Wareham, Ken K. Ong, Ruth J. F. Loos, Daniel I. Chasman, Erik Ingelsson … & Paul W. Franks
Phenotypic variance heterogeneity across genotypes at a single nucleotide polymorphism (SNP) may reflect underlying gene-environment (G·E) or gene-gene interactions. We modeled variance heterogeneity for blood lipids and BMI in up to 44,211 participants and investigated relationships between variance effects (Pv), G·E interaction effects (with smoking and physical activity), and marginal genetic effects (Pm). Correlations between Pv and Pm were stronger for SNPs with established marginal effects (Spearman's ρ=0.401 for triglycerides, and ρ=0.236 for BMI) compared...

Data from: The consequences of sexual selection in well-adapted and maladapted populations of bean beetles

Ivain Martinossi-Allibert, Uroš Savković, Mirko Đorđević, Göran Arnqvist, Biljana Stojkovic & David Berger
Whether sexual selection generally promotes or impedes population persistence remains an open question. Intralocus sexual conflict (IaSC) can render sexual selection in males detrimental to the population by increasing the frequency of alleles with positive effects on male reproductive success but negative effects on female fecundity. Recent modelling based on fitness landscape theory, however, indicates that the relative impact of IaSC may be reduced in maladapted populations and that sexual selection therefore might promote adaptation...

Data from: Inferring dispersal across a fragmented landscape using reconstructed families in the Glanville fritillary butterfly

Toby Fountain, Arild Husby, Etsuko Nonaka, Michelle F. DiLeo, Janne H. Korhonen, Pasi Rastas, Torsti Schulz, Marjo Saastamoinen & Ilkka Hanski
Dispersal is important for determining both a species ecological processes, such as population viability, and its evolutionary processes, like gene flow and local adaptation. Yet obtaining accurate estimates in the wild through direct observation can be challenging or even impossible, particularly over large spatial and temporal scales. Genotyping many individuals from wild populations can provide detailed inferences about dispersal. We therefore utilized genomewide marker data to estimate dispersal in the classic metapopulation of the Glanville...

Data from: Sex differences in adult mortality rate mediated by early-life environmental conditions

Robert M. Griffin, Adam D. Hayward, Elisabeth Bolund, Alexei A. Maklakov & Virpi Lummaa
Variation in sex differences is affected by both genetic and environmental variation, with rapid change in sex differences being more likely due to environmental change. One case of rapid change in sex differences is human lifespan, which has become increasingly female-biased in recent centuries. Long-term consequences of variation in the early-life environment may, in part, explain such variation in sex differences, but whether the early-life environment mediates sex differences in life-history traits is poorly understood...

Data from: Interaction intensity and pollinator-mediated selection

Judith Trunschke, Nina Sletvold & Jon Agren
In animal-pollinated plants, the opportunity for selection and the strength of pollinator-mediated selection are expected to increase with the degree of pollen limitation. However, whether differences in pollen limitation can explain variation in pollinator-mediated and net selection among animal-pollinated species is poorly understood. In the present study, we quantified pollen limitation, variance in relative fitness and pollinator-mediated selection on five traits important for pollinator attraction (flowering start, plant height, flower number, flower size) and pollination...

Data from: Ontogenetic timing as a condition-dependent life history trait: high-condition males develop quickly, peak early and age fast

Amy K. Hooper, Foteini Spagopoulou, Zachariah Gilmer Wylde, Alexei A. Maklakov, Russell Bonduriansky & Zachariah Wylde
Within-population variation in ageing remains poorly understood. In males, condition-dependent investment in secondary sexual traits may incur costs which limit ability to invest in somatic maintenance. Moreover, males often express morphological and behavioural secondary sexual traits simultaneously, but the relative effects on ageing of investment in these traits remain unclear. We investigated the condition-dependence of male life history in the neriid fly Telostylinus angusticollis. Using a fully factorial design, we manipulated male early-life condition by...

Data from: Experience buffers extrinsic mortality in a group-living bird species

Michael Griesser, Emeline Mourocq, Jonathan Barnaby, Katharine Bowegen, Sönke Eggers, Kevin Fletcher, Radoslav Kozma, Franziska Kurz, Anssi Laurila, Magdalena Nystrand, Enrico Sorato, Jan Ekman & Katharine M. Bowgen
Extrinsic mortality has a strong impact on the evolution of life-histories, prey morphology and behavioural adaptations, but for many animals the causes of mortality are poorly understood. Predation is an important driver of extrinsic mortality and mobile animals form groups in response to increased predation risk. Furthermore, in many species juveniles suffer higher mortality than older individuals, which may reflect a lower phenotypic quality, lower competitiveness, or a lack of antipredator or foraging skills. Here...

Data from: Evolutionary associations between host traits and parasite load: insights from Lake Tanganyika cichlids

Alexander Hayward, Masahito Tsuboi, Christian Owusu, Kotrschal Alexander, Severine D. Buechel, Josefina Zidar, Charlie K. Cornwallis, Hanne Lovlie, Niclas Kolm & A. Kotrschal
Parasite diversity and abundance (parasite load) vary greatly among host species. However, the influence of host traits on variation in parasitism remains poorly understood. Comparative studies of parasite load have largely examined measures of parasite species richness and are predominantly based on records obtained from published data. Consequently, little is known about the relationships between host traits and other aspects of parasite load, such as parasite abundance, prevalence and aggregation. Meanwhile, understanding of parasite species...

Data from: Female fecundity variation affects reproducibility of experiments on host plant preference and acceptance in a phytophagous insect

Alexander Schäpers, Hampus Petrén, Christopher W. Wheat, Christer Wiklund & Magne Friberg
Reproducibility is a scientific cornerstone. Many recent studies, however, describe a reproducibility crisis and call for assessments of reproducibility across scientific domains. Here, we explore the reproducibility of a classic ecological experiment—that of assessing female host plant preference and acceptance in phytophagous insects, a group in which host specialization is a key driver of diversification. We exposed multiple cohorts of Pieris napi butterflies from the same population to traditional host acceptance and preference tests on...

Data from: Evolution of brain region volumes during artificial selection for relative brain size

Alexander Kotrschal, Hong-Li Zeng, Wouter Van Der Bijl, Caroline Öhman-Mägi, Kurt Kotrschal, Kristiaan Pelckmans & Niclas Kolm
The vertebrate brain shows an extremely conserved layout across taxa. Still, the relative sizes of separate brain regions vary markedly between species. One interesting pattern is that larger brains seem associated with increased relative sizes only of certain brain regions, for instance telencephalon and cerebellum. Till now, the evolutionary association between separate brain regions and overall brain size is based on comparative evidence and remains experimentally untested. Here we test the evolutionary response of brain...

Data from: DNA metabarcoding of orchid-derived products reveals widespread illegal orchid trade

In eastern Mediterranean countries orchids continue to be collected from the wild for the production of salep, a beverage made of dried orchid tubers. In this study we used nrITS1 and nrITS2 DNA metabarcoding to identify orchid and other plant species present in 55 commercial salep products purchased in Iran, Turkey, Greece and Germany. Thirty samples yielded a total of 161 plant taxa, and 13 products (43%) contained orchid species and these belonged to 10...

Data from: Reproductive character displacement of female, but not male song discrimination in an avian hybrid zone

David Wheatcroft & Anna Qvarnstrom
Divergence of male sexual signals and female preferences for those signals often maintains reproductive boundaries between closely related, co-occurring species. However, contrasting sources of selection, such as interspecific competition, can lead to weak divergence or even convergence of sexual signals in sympatry. When signals converge, assortative mating can be maintained if the mating preferences of females diverge in sympatry (reproductive character displacement; RCD), but there are few explicit examples. Pied flycatchers (Ficedula hypoleuca) are sympatric...
