Data from: Co-inheritance of sea age at maturity and iteroparity in the Atlantic salmon vgll3 genomic region

Tutku Aykanat, Mikhail Ozerov, Juha-Pekka Vähä, Panu Orell, Eero Niemelä, Jaakko Erkinaro & Craig R Primmer
Co-inheritance in life history traits may result in unpredictable evolutionary trajectories if not accounted for in life-history models. Iteroparity (the reproductive strategy of reproducing more than once) in Atlantic salmon (Salmo salar) is a fitness trait with substantial variation within and among populations. In the Teno River in northern Europe, iteroparous individuals constitute an important component of many populations and have experienced a sharp increase in abundance in the last 20 years, partly overlapping with...

Data from: Patterns of modern pollen and plant richness across northern Europe

Triin Reitalu, Anne E. Bjune, Ansis Blaus, Thomas Giesecke, Aveliina Helm, Isabelle Matthias, Sylvia H. Peglar, J. Sakari Salonen, Heikki Seppa, Vivika Väli & H. John B. Birks
1. Sedimentary pollen offers excellent opportunities to reconstruct vegetation changes over past millennia. Number of different pollen taxa or pollen richness is used to characterise past plant richness. To improve the interpretation of sedimentary pollen richness, it is essential to understand the relationship between pollen and plant richness in contemporary landscapes. This study presents a regional-scale comparison of pollen and plant richness from northern Europe and evaluates the importance of environmental variables on pollen and...

Data from: Epigenome-wide association study of lung function level and its change

Medea Imboden, Matthias Wielscher, Faisal I Rezwan, Andre F S Amaral, Emmanuel Schaffner, Ayoung Jeong, Anna Beckmeyer-Borowko, Sarah E Harris, John M Starr, Ian J Deary, Claudia Flexeder, Melanie Waldenberger, Annette Peters, Holger Schulz, Su Chen, Shadia KHan Sunny, Wilfried J J Karmaus, Yu Jiang, Gertraud Erhart, Florian Kronenberg, Ryan Arathimos, Gemma C Sharp, Alexander John Henderson, Yu Fu, Paivi Piirila … & Nicole M Probst-Hensch
Previous reports link differential DNA methylation (DNAme) to environmental exposures which are associated with lung function. Direct evidence on lung function DNAme is however limited. We undertook an agnostic epigenome-wide association study (EWAS) on pre-bronchodilation lung function and its change in adults. In a discovery-replication EWAS design, DNAme in blood and spirometry were measured twice, six-to-15 years apart, in the same participants of three adult population-based discovery cohorts (n=2,043). Associated DNAme markers (P<5x10-7) were tested...

Data from: Growth mode and carbon source impact the surfaceome dynamics of Lactobacillus rhamnosus GG

Kirsi Savijoki, Tuula A. Nyman, Veera Kainulainen, Ilkka Miettinen, Pia Siljamäki, Adyary Fallarero, Jouko Sandholm, Reetta Satokari & Pekka Varmanen
Bacterial biofilms have clear implications in disease and in food applications involving probiotics. Here, we show that switching the carbohydrate source from glucose to fructose increased the biofilm formation and the total surface-antigenicity of a well-known probiotic, Lactobacillus rhamnosus GG. Surfaceomes (all cell surface-associated proteins) of GG cells grown with glucose and fructose in planktonic and biofilm cultures were identified and compared, which indicated carbohydrate source-dependent variations, especially during biofilm growth. The most distinctive differences...

Data from: Water as a resource, stress and disturbance shaping tundra vegetation

Julia Kemppinen, Pekka Niittynen, Juha Aalto, Peter C. Le Roux & Miska Luoto
Water is crucial for plant productivity and survival as a fundamental resource, but water conditions can also cause physiological stress and mechanical disturbance to vegetation. However, these different influences of water on vegetation patterns have not been evaluated simultaneously. Here, we demonstrate the importance of three water aspects (spatial and temporal variation of soil moisture and fluvial disturbance) for three ecologically and evolutionary distinct taxonomical groups (vascular plants, mosses, and lichens) in Fennoscandian mountain tundra....

Data from: Is evolution predictable? quantitative genetics under complex genotype-phenotype maps

Lisandro Milocco
A fundamental aim of post-genomic 21st century biology is to understand the genotype-phenotype map (GPM) or how specific genetic variation relates to specific phenotypic variation. Quantitative genetics approximates such maps using linear models, and has developed methods to predict the response to selection in a population. The other major field of research concerned with the GPM, developmental evolutionary biology or evo-devo, has found the GPM to be highly nonlinear and complex. Here we quantify how...

Estimating uncertainty in divergence times among three-spined stickleback clades using the multispecies coalescent

Bohao Fang, Juha Merilä, Michael Matschiner & Paolo Momigliano
Incomplete lineage sorting (ILS) can lead to biased divergence time estimates. To explore if and how ILS has influenced the results of a recent study of worldwide phylogeny of three-spined sticklebacks (Gasterosteus aculeatus), we estimated divergence times among major clades by applying both a concatenation approach and the multispecies coalescent (MSC) model to single-nucleotide polymorphisms. To further test the influence of different calibration strategies, we applied different calibrations to the root and to younger nodes...

Data from: Size‐dependent stress response in juvenile Arctic charr (Salvelinus alpinus) under prolonged predator conditioning

Raine Kortet, Mika V.M. Laakkonen, Jouni Tikkanen, Anssi Vainikka & Heikki Hirvonen
Predator conditioning can be used to improve post-release antipredator recognition of hatchery-reared salmonids. However, possible negative stress-related effects of prolonged predator conditioning on juvenile fish physiology are poorly understood. We studied the effects of prolonged (91 days) predator odour exposure on whole-body cortisol level and spleen size in six full-sib families of juvenile hatchery-bred Arctic charr (Salvelinus alpinus). Chemical cues from water containing charr-fed pikeperch (Sander lucioperca) were used as the predator exposure stimuli, and...

Data from: Home ground advantage: local Atlantic salmon have higher reproductive fitness than dispersers in the wild

Kenyon B. Mobley, Hanna Granroth-Wilding, Mikko Ellmen, Juha-Pekka Vähä, Tutku Aykanat, Susan E. Johnston, Panu Orell, Jaakko Erkinaro & Craig R. Primmer
A long-held, but poorly tested, assumption in natural populations is that individuals that disperse into new areas for reproduction are at a disadvantage compared to individuals that reproduce in their natal habitat, underpinning the eco-evolutionary processes of local adaptation and ecological speciation. Here, we capitalize on fine-scale population structure and natural dispersal events to compare the reproductive success of local and dispersing individuals captured on the same spawning ground in four consecutive parent-offspring cohorts of...

Data from: Carbon dioxide and methane fluxes from different surface types in a created urban wetland

Xuefei Li, Outi Wahlroos, Sami Haapanala, Jukka Pumpanen, Harri Vasander, Anna Ojala1, Timo Vesala & Ivan Mammarella
Many wetlands have been drained due to urbanization, agriculture, forestry or other purposes, which has resulted in losing their ecosystem services. To protect receiving waters and to achieve services such as flood control and stormwater quality mitigation, new wetlands are created in urbanized areas. However, our knowledge of greenhouse gas exchange in newly created wetlands in urban areas is currently limited. In this paper we present measurements carried out at a created urban wetland in...

Data from: A four-questions perspective on public information use in sticklebacks (Gasterosteidae)

Mike M. Webster, Laura Chouinard-Thuly, Gábor Herczeg, Jun Kitano, Riva Riley, Sean Rogers, Michael D. Shapiro, Takahito Shikano & Kevin N. Laland
Whether learning primarily reflects general processes or species-specific challenges is a longstanding matter of dispute. Here we present a comprehensive analysis of public information use (PI-use) in sticklebacks (Gasterosteidae). PI-use is a form of social learning by which animals are able to assess the relative quality of resources, here prey patches, by observing the behaviour of others. PI-use was highly species-specific with only two of the assayed species, Pungitius spp. and their closest relative Culaea...

Data from: Megaphylogeny resolves global patterns of mushroom evolution

Torda Varga, Krisztina Krizsán, Csenge Földi, Bálint Dima, Marisol Sánchez-García, Santiago Sánchez-Ramírez, Gergely J. Szöllősi, János G. Szarkándi, Viktor Papp, László Albert, William Andreopoulos, Claudio Angelini, Vladimír Antonín, Kerrie W. Barry, Neale L. Bougher, Peter Buchanan, Bart Buyck, Viktória Bense, Pam Catcheside, Mansi Chovatia, Jerry Cooper, Wolfgang Dämon, Dennis Desjardin, Péter Finy, József Geml … & László G. Nagy
Mushroom-forming fungi (Agaricomycetes) have the greatest morphological diversity and complexity of any group of fungi. They have radiated into most niches and fulfill diverse roles in the ecosystem, including wood decomposers, pathogens or mycorrhizal mutualists. Despite the importance of mushroom-forming fungi, large-scale patterns of their evolutionary history are poorly known, in part due to the lack of a comprehensive and dated molecular phylogeny. Here, using multigene and genome-based data, we assemble a 5,284-species phylogenetic tree...

Data from: Diversity patterns of native and exotic fish species suggest homogenization processes, but partly fail to highlight extinction threats

Anna Gavioli, Marco Milardi, Giuseppe Castaldelli, Elisa Anna Fano & Janne Soininen
Exotic species are a major threat to biodiversity and have modified native communities worldwide. Invasion processes have been extensively studied, but studies on species richness and beta diversity patterns of exotic and native species are rare. We investigate such patterns among exotic and native fish communities in upland and lowland rivers to explore their relationship with environmental drivers. Location: Northern Italy. Exotic and native fish beta diversity patterns were investigated separately in lowland and upland...

Data from: Extended haplodiploidy hypothesis

Petri Rautiala, Heikki Helanterä & Mikael Puurtinen
Evolution of altruistic behaviour was a hurdle for the logic of Darwinian evolution. Soon after Hamilton formalised the concept of inclusive fitness, which explains how altruism can evolve, he suggested that the high sororal relatedness brought by haplodiploidy could be why Hymenopterans have a high prevalence in eusocial species, and why helpers in Hymenoptera are always female. Later it was noted that in order to capitalize on the high sororal relatedness, helpers would need to...

In this paper we studied, how five years of experimental warming and increased soil nitrogen availability interact with both long- and short-term differences in...

Data from: Limited thermal plasticity and geographic divergence in the ovipositor of Drosophila suzukii

Ceferino Varón González, Antoine Fraimout, Arnaud Delapré, Vincent Debat & Raphaël Cornette
Phenotypic plasticity has been repeatedly suggested to facilitate adaptation to new environmental conditions, as in invasions. Here we investigate this possibility by focusing on the worldwide invasion of Drosophila suzukii: an invasive species that has rapidly colonized all continents over the last decade. This species is characterized by a highly developed ovipositor, allowing females to lay eggs through the skin of ripe fruits. Using a novel approach based on the combined use of SEM and...

Modular chromosome rearrangements reveal parallel and nonparallel adaptation in a marine fish

Tony Kess, Paul Bentzen, Sarah Lehnert, Emma Sylvester, Sigbjørn Lien, Matthew Kent, Marion Sinclair-Waters, Corey Morris, Brendan Wringe, Robert Fairweather & Ian Bradbury
Genomic architecture and standing variation can play a key role in ecological adaptation, and contribute to the predictability of evolution. In Atlantic cod (Gadus morhua), four large chromosomal rearrangements have been associated with ecological gradients and migratory behaviour in regional analyses. However, the degree of parallelism , the extent of independent inheritance, and functional distinctiveness of these rearrangements remains poorly understood. Here, we use a 12K single nucleotide polymorphism (SNP) array to demonstrate extensive individual...

Data from: Predators’ consumption of unpalatable prey does not vary as a function of bitter taste perception

Liisa Hämäläinen, Johanna Mappes, Rose Thorogood, Janne Valkonen, Kaijamari Karttunen, Tuuli Salmi & Hannah Rowland
Many prey species contain defensive chemicals that are described as tasting bitter. Bitter taste perception is therefore assumed to be important when predators are learning about prey defenses. However, it is not known how individuals differ in their response to bitter taste, and how this influences their foraging decisions. We conducted taste perception assays in which wild-caught great tits (Parus major) were given water with increasing concentrations of bitter-tasting chloroquine diphosphate until they showed an...

Data from: Long-term demographic surveys reveal a consistent relationship between average occupancy and abundance within local populations of a butterfly metapopulation

Torsti Schulz, Jarno Vanhatalo & Marjo Saastamoinen
Species distribution models are the tool of choice for large-scale population monitoring, environmental association studies, and predictions of range shifts under future environmental conditions. Available data and familiarity of the tools rather than the underlying population dynamics often dictate the choice of specific method — especially for the case of presence–absence data. Yet, for predictive purposes, the relationship between occupancy and abundance embodied in the models should reflect the actual population dynamics of the modelled...

Data from: Joint evolution of dispersal and connectivity

Petteri Karisto & Eva Kisdi
Functional connectivity, the realized flow of individuals between the suitable sites of a heterogeneous landscape, is a prime determinant of the maintenance and evolution of populations in fragmented habitats. While a large body of literature examines the evolution of dispersal propensity, it is less known how evolution shapes functional connectivity via traits that influence the distribution of the dispersers. Here we use a simple model to demonstrate that, in a heterogeneous environment with clustered and...

Data from: Effects of marker type and filtering criteria on QST-FST comparisons

Zitong Li, Ari Löytynoja, Antoine Fraimout & Juha Merilä
Comparative studies of quantitative and neutral genetic differentiation (QST-FST tests) provide means to detect adaptive population differentiation. However, QST-FST tests can be overly liberal if the markers used deflate FST below its expectation, or overly conservative if methodological biases lead to inflated FST estimates. We investigated how marker type and filtering criteria for marker selection influence QST-FST comparisons through their effects on FST using simulations and empirical data on over 18 000 in silico genotyped...

Data from: Ornithine Decarboxylase Antizyme Inhibitor 2 (AZIN2) is a signature of secretory phenotype and independent predictor of adverse prognosis in colorectal cancer

Tuomas Kaprio, Tina Rasila, Jaana Hagström, Harri Mustonen, Caj Haglund & Leif C. Andersson
Ornithine decarboxylase (ODC) is the rate-limiting enzyme of polyamine synthesis. The two ODC antizyme inhibitors (AZIN1) and (AZIN2) are regulators of the catalytic activity of ODC. While AZIN1 is a regulator of cell proliferation, AZIN2 is involved in intracellular vesicle transport and secretion. There are no previous reports on the impact of AZIN2 expression in human cancer. We applied immunohistochemistry with antibodies to human AZIN2 on tissue micro- arrays of colorectal cancers (CRC) from 840...

Data from: Tail color signals performance in blue tit nestlings

Barbara Class, Edward Kluen & Jon E. Brommer
Indirect sexual selection arises when reproductive individuals choose their mates based on heritable ornaments that are genetically correlated to fitness. Evidence for genetic associations between ornamental coloration and fitness remain scarce. In this study we investigate the quantitative genetic relationship between different aspects of tail structural coloration (brightness, hue and UV chroma) and performance (cell mediated immunity, body mass and wing length) in blue tit (Cyanistes caeruleus) nestlings. In line with previous studies, we find...
