Data from: Cold tadpoles from Arctic environments waste less nutrients – high gross growth efficiencies lead to low consumer-mediated nutrient recycling in the North

Antonia Liess, Martin I. Lind, Junwen Guo & Owen Rowe
1. Endothermic organisms can adapt to short growing seasons, low temperatures and nutrient limitation by developing high growth rates and high gross growth efficiencies (GGEs). Animals with high GGEs are better at assimilating limiting nutrients and thus should recycle (or lose) fewer nutrients. Longer guts in relation to body mass may facilitate higher GGE under resource limitation. 2. Within the context of ecological stoichiometry theory, this study combines ecology with evolution by relating latitudinal life-history...

Data from: Relaxed predation results in reduced phenotypic integration in a suite of dragonflies

Dirk Johannes Mikolajewski, Linda Rüsen, Rüdiger Mauersberger, Frank Johansson & Jens Rolff
While changes in magnitude of single traits responding to selective agents have been studied intensively, little is known about selection shaping networks of traits and their patterns of co-variation. However, this is central for our understanding of phenotypic evolution since traits are embedded in a multivariate environment with selection affecting a multitude of traits simultaneously rather than individually. Here, we investigate inter- and intraspecific patterns of trait integration (trait correlations) in the larval abdomen of...

Data from: Fine-scale kin recognition in the absence of social familiarity in the Siberian jay, a monogamous bird species

Michael Griesser, Peter Halvarsson, Szymon M. Drobniak & Carles Vilà
Kin recognition is a critical element to kin cooperation, and in vertebrates, it is primarily based on associative learning. Recognition of socially unfamiliar kin occurs rarely, and it is reported only in vertebrate species where promiscuity prevents recognition of first-order relatives. However, it is unknown whether the recognition of socially unfamiliar kin can evolve in monogamous species. Here, we investigate whether genetic relatedness modulates aggression among group members in Siberian jays (Perisoreus infaustus). This bird...

Data from: The evolutionary history of ferns inferred from 25 low-copy nuclear genes

Carl J. Rothfels, Fay-Wei Li, Erin M. Sigel, Layne Huiet, Anders Larsson, Dylan O. Burge, Markus Ruhsam, Michael Deyholos, Douglas E. Soltis, , Shane W. Shaw, Lisa Pokorny, Tao Chen, Claude DePamphilis, Lisa DeGironimo, Li Chen, Xiaofeng Wei, Xiao Sun, Petra Korall, Dennis W. Stevenson, Sean W. Graham, Gane Ka-Shu Wong, Kathleen M. Pryer, C. Neal Stewart, Gane K-S. Wong … & Claude De Pamphilis
Premise of the study: Understanding fern (monilophyte) phylogeny and its evolutionary timescale is critical for broad investigations of the evolution of land plants, and for providing the point of comparison necessary for studying the evolution of the fern sister group, seed plants. Molecular phylogenetic investigations have revolutionized our understanding of fern phylogeny, however, to date, these studies have relied almost exclusively on plastid data. Methods: Here we take a curated phylogenomics approach to infer the...

Data from: Effects of the demographic transition on the genetic variances and covariances of human life history traits

Elisabeth Bolund, Adam Hayward, Jenni E. Pettay & Virpi Lummaa
The recent demographic transitions to lower mortality and fertility rates in most human societies have led to changes and even quick reversals in phenotypic selection pressures. This can only result in evolutionary change if the affected traits are heritable, but changes in environmental conditions may also lead to subsequent changes in the genetic variance and covariance (the G matrix) of traits. It currently remains unclear if there have been concomitant changes in the G matrix...

Data from: How a haemosporidian parasite of bats gets around: the genetic structure of a parasite, vector and host compared

Fardo Witsenburg, Laura Clément, Ludovic Dutoit, Adrià López-Baucells, Jorge Palmeirim, Dino Scaravelli, Martin Ševčík, Nicolas Salamin, Jérôme Goudet, Philippe Christe & Igor Pavlinić
Parasite population structure is often thought to be largely shaped by that of its host. In the case of a parasite with a complex life cycle, two host species, each with their own patterns of demography and migration, spread the parasite. However, the population structure of the parasite is predicted to resemble only that of the most vagile host species. In this study we tested this prediction in the context of a vector-transmitted parasite. We...

Data from: A new family of Cambrian rhynchonelliformean brachiopods (Order Naukatida) with an aberrant coral-like morphology

Michael Streng, Aodhán D. Butler, John S. Peel, Russell J. Garwood & Jean-Bernard Caron
Tomteluva perturbata gen. et sp. nov. and Nasakia thulensis gen. et sp. nov., two new rhynchonelliformean brachiopod taxa, are described from carbonate beds from the lower middle Cambrian (Series 3, Stage 5) basinal Stephen Formation, Canada, and the upper lower Cambrian (Series 2, Stage 4) Henson Gletscher Formation, North Greenland, respectively. The two taxa are characterized by an unusual coral-like morphology typified by a high conical ventral valve with an anteriorly curved umbo and a...

Data from: The shepherds' tale: a genome-wide study across 9 dog breeds implicates two loci in the regulation of fructosamine serum concentration in Belgian shepherds

Simon K. G. Forsberg, Marcin Kierczak, Ingrid Ljungvall, Anne-Christine Merveille, Vassiliki Gouni, Maria Wiberg, Jakob Lundgren Willesen, Sofia Hanås, Anne-Sophie Lequarré, Louise Mejer Sørensen, Laurent Tiret, Kathleen McEntee, Eija Seppälä, Jørgen Koch, Géraldine Battaille, Hannes Lohi, Merete Fredholm, Valerie Chetboul, Jens Häggström, Örjan Carlborg, Kerstin Lindblad-Toh & Katja Höglund
Diabetes mellitus is a serious health problem in both dogs and humans. Certain dog breeds show high prevalence of the disease, whereas other breeds are at low risk. Fructosamine and glycated hemoglobin (HbA1c) are two major biomarkers of glycaemia where serum concentrations reflect glucose turnover over the past few weeks to months. In this study, we searched for genetic factors influencing variation in serum fructosamine concentration in healthy dogs using data from nine dog breeds....

Data from: How mechanisms of habitat preference evolve and promote divergence with gene flow

Daniel Berner & Xavier Thibert-Plante
Habitat preference may promote adaptive divergence and speciation, yet the conditions under which this is likely are insufficiently explored. We use individual-based simulations to study the evolution and consequence of habitat preference during divergence with gene flow, considering four different underlying genetically-based behavioral mechanisms: natal habitat imprinting, phenotype-dependent, competition-dependent, and direct genetic habitat preference. We find that the evolution of habitat preference generally requires initially high dispersal, is facilitated by asymmetry in population sizes between...

Data from: Genome-wide association mapping in a wild avian population identifies a link between genetic and phenotypic variation in a life-history trait

Arild Husby, Takeshi Kawakami, Lars Rönnegård, Linnéa Smeds, Hans Ellegren, Anna Qvarnström, L. Ronnegard & A. Qvarnstrom
Understanding the genetic basis of traits involved in adaptation is a major challenge in evolutionary biology but remains poorly understood. Here, we use genome-wide association mapping using a custom 50 k single nucleotide polymorphism (SNP) array in a natural population of collared flycatchers to examine the genetic basis of clutch size, an important life-history trait in many animal species. We found evidence for an association on chromosome 18 where one SNP significant at the genome-wide...

Data from: Serendipitous meta-transcriptomics: the fungal community of Norway spruce (Picea abies)

Nicolas Delhomme, Görel Sundström, Neda Zamani, Henrik Lantz, Yao-Cheng Lin, Torgeir R. Hvidsten, Marc P. Höppner, Patric Jern, Yves Van De Peer, Joakim Lundeberg, Manfred G. Grabherr & Nathaniel R. Street
After performing de novo transcript assembly of >1 billion RNA-Sequencing reads obtained from 22 samples of different Norway spruce (Picea abies) tissues that were not surface sterilized, we found that assembled sequences captured a mix of plant, lichen, and fungal transcripts. The latter were likely expressed by endophytic and epiphytic symbionts, indicating that these organisms were present, alive, and metabolically active. Here, we show that these serendipitously sequenced transcripts need not be considered merely as...

Data from: Affinity, life cycle, and intracellular complexity of organic-walled 2 microfossils from the Mesoproterozoic of Shanxi, China

Heda Agić, Małgorzata Moczydłowska & Lei-Ming Yin
Light microscope and scanning electron microscope observations on new material of unicellular microfossils Dictyosphaera macroreticulata and Shuiyousphaeridium macroreticulatum, from the Mesoproterozoic Ruyang Group in China, provide insights into the microorganisms’ biological affinity, life cycle and cellular complexity. Gigantosphaeridium fibratum n. gen. et sp., is described and is one of the largest Mesoproterozoic microfossils recorded. Phenotypic characters of vesicle ornamentation and excystment structures, properties of resistance and cell wall structure in Dictyosphaera and Shuiyousphaeridium are all...

Data from: The genetic basis of color-related local adaptation in a ring-like colonization around the Mediterranean

Reto Burri, Sylvain Antoniazza, Arnaud Gaigher, Anne-Lyse Ducrest, Céline Simon, The European Barn Owl Network, Luca Fumagalli, Jerome Goudet & Alexandre Roulin
Uncovering the genetic basis of phenotypic variation and the population history under which it established is key to understand the trajectories along which local adaptation evolves. Here, we investigated the genetic basis and evolutionary history of a clinal plumage color polymorphism in European barn owls (Tyto alba). Our results suggest that barn owls colonized the Western Palearctic in a ring-like manner around the Mediterranean and meet in secondary contact in Greece. Rufous coloration appears to...

Data from: Within species support for the expensive tissue hypothesis: a negative association between brain size and visceral fat storage in females of the Pacific seaweed pipefish

Masahito Tsuboi, Jun Shoji, Atsushi Sogabe, Ingrid Ahnesjö & Niclas Kolm
The brain is one of the most energetically expensive organs in the vertebrate body. Consequently, the high cost of brain development and maintenance is predicted to constrain adaptive brain size evolution (the expensive tissue hypothesis, ETH). Here, we test the ETH in a teleost fish with predominant female mating competition (reversed sex roles) and male pregnancy, the pacific seaweed pipefish Syngnathus schlegeli. The relative size of the brain and other energetically expensive organs (kidney, liver,...

Data from: Looking into the past – the reaction of three grouse species to climate change over the last million years using whole genome sequences

Radoslav Kozma, Páll Melsted, Kristinn P. Magnússon & Jacob Höglund
Tracking past population fluctuations can give insight into current levels of genetic variation present within species. Analysing population dynamics over larger time scales can be aligned to known climatic changes to determine the response of species to varying environments. Here, we applied the Pairwise Sequentially Markovian Coalescent (PSMC) model to infer past population dynamics of three widespread grouse species; black grouse, willow grouse and rock ptarmigan. This allowed the tracking of the effective population size...

Data from: Into and out of the tropics: global diversification patterns in a hyper-diverse clade of ectomycorrhizal fungi

Brian P. Looney, Martin Ryberg, Felix Hampe, Marisol Sánchez-García & P. Brandon Matheny
Ectomycorrhizal (ECM) fungi, symbiotic mutualists of many dominant tree and shrub species, exhibit a biogeographic pattern counter to the established latitudinal diversity gradient of most macroflora and fauna. However, an evolutionary basis for this pattern has not been explicitly tested in a diverse lineage. In this study, we reconstructed a mega-phylogeny of a cosmopolitan and hyper-diverse genus of ECM fungi, Russula, sampling from annotated collections and utilizing publically available sequences deposited in GenBank. Metadata from...

Data from: Evolution of haploid selection in predominantly diploid organisms

Sarah P. Otto, Michael F. Scott & Simone Immler
Diploid organisms manipulate the extent to which their haploid gametes experience selection. Animals typically produce sperm with a diploid complement of most proteins and RNA, limiting selection on the haploid genotype. Plants, however, exhibit extensive expression in pollen, with actively transcribed haploid genomes. Here we analyze models that track the evolution of genes that modify the strength of haploid selection to predict when evolution intensifies and when it dampens the “selective arena” within which male...

Data from: Seasonal time constraints reduce genetic variation in life history traits along a latitudinal gradient

Szymon Śniegula, Maria J. Golab, Szymon M. Drobniak & Frank Johansson
1. Time constraints cause strong selection on life history traits, because populations need to complete their life cycles within a shorter time. We therefore expect lower genetic variation in these traits in high- than in low-latitude populations, since the former are more time constrained. 2. The aim was to estimate life history traits and their genetic variation in an obligately univoltine damselfly along a latitudinal gradient of 2,730 km. 3. Populations were grown in the...

Data from: Latitudinal variation in resistance and tolerance to herbivory in the perennial herb Lythrum salicaria is related to intensity of herbivory and plant phenology

Lina Lehndal & Jon Ågren
Both the length of the growing season and the intensity of herbivory often vary along climatic gradients, which may result in divergent selection on plant phenology, and on resistance and tolerance to herbivory. In Sweden, the length of the growing season and the number of insect herbivore species feeding on the perennial herb Lythrum salicaria decrease from south to north. Previous common-garden experiments have shown that northern L. salicaria populations develop aboveground shoots earlier in...

Data from: Male seminal fluid substances affect sperm competition success and female reproductive behavior in a seed beetle

Takashi Yamane, Julieta Goenaga, Johanna Liljestrand Rönn & Göran Arnqvist
Male seminal fluid proteins are known to affect female reproductive behavior and physiology by reducing mating receptivity and by increasing egg production rates. Such substances are also though to increase the competitive fertilization success of males, but the empirical foundation for this tenet is restricted. Here, we examined the effects of injections of size-fractioned protein extracts from male reproductive organs on both male competitive fertilization success (i.e., P2 in double mating experiments) and female reproduction...

Data from: Direct and indirect genetic effects of sex-specific mitonuclear epistasis on reproductive ageing

Elina Immonen, Marie Collet, Julieta Goenaga & Göran Arnqvist
Mitochondria are involved in ageing and their function requires coordinated action of both mitochondrial and nuclear genes. Epistasis between the two genomes can influence lifespan but whether this also holds for reproductive senescence is unclear. Maternal inheritance of mitochondria predicts sex differences in the efficacy of selection on mitonuclear genotypes that should result in differences between females and males in mitochondrial genetic effects. Mitonuclear genotype of a focal individual may also indirectly affect trait expression...

Data from: Complex mitonuclear interactions and metabolic costs of mating in male seed beetles

Elina Immonen, Johanna Liljestrand-Rönn, Christopher Watson, David Berger & Göran Arnqvist
The lack of evolutionary response to selection on mitochondrial genes through males predicts the evolution of nuclear genetic influence on male-specific mitochondrial function, for example by gene duplication and evolution of sex-specific expression of paralogs involved in metabolic pathways. Intergenomic epistasis may therefore be a prevalent feature of the genetic architecture of male-specific organismal function. Here, we assess the role of mitonuclear genetic variation for male metabolic phenotypes [metabolic rate and respiratory quotient (RQ)] associated...

Data from: Maternal environment affects the genetic basis of seed dormancy in Arabidopsis thaliana

Froukje M. Postma & Jon Ågren
The genetic basis of seed dormancy, a key life-history trait important for adaptive evolution in plant populations, has yet been studied only using seeds produced under controlled conditions in greenhouse environments. However, dormancy is strongly affected by maternal environmental conditions, and interactions between seed genotype and maternal environment have been reported. Consequently, the genetic basis of dormancy of seeds produced under natural field conditions remains unclear. We examined the effect of maternal environment on the...

Data from: Herbivory differentially affects plant fitness in three populations of the perennial herb Lythrum salicaria along a latitudinal gradient

Lina Lehndal & Jon Ågren
Herbivory can negatively and selectively affect plant fitness by reducing growth, survival and reproductive output, thereby influencing plant population dynamics and evolution. Latitudinal variation in intensity of herbivory is common, but the extent to which it translates into corresponding variation in effects on plant performance is still poorly known. We tested the hypothesis that variation in the fitness-consequences of herbivory mirror differences in intensity of herbivory among three natural populations of the perennial herb Lythrum...

Data from: Experimental taphonomy of Artemia reveals the role of endogenous microbes in mediating decay and fossilization

Aodhán D. Butler, John A. Cunningham, Graham E. Budd & Philip C. J. Donoghue
Exceptionally preserved fossils provide major insights into the evolutionary history of life. Microbial activity is thought to play a pivotal role in both the decay of organisms and the preservation of soft tissue in the fossil record, though this has been the subject of very little experimental investigation. To remedy this, we undertook an experimental study of the decay of the brine shrimp Artemia, examining the roles of autolysis, microbial activity, oxygen diffusion and reducing...
