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: 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: 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: Adaptation to local climate in a multi-trait space: evidence from silver fir (Abies alba Mill.) populations across a heterogeneous environment

Katalin Csilléry, Otso Ovaskainen, Christoph Sperisen, Nina Buchmann, Alex Widmer & Felix Gugerli
Heterogeneous environments, such as mountainous landscapes, create spatially varying selection pressure that potentially affects several traits simultaneously across different life stages, yet little is known about the general patterns and drivers of adaptation in such complex settings. We studied silver fir (Abies alba Mill.) populations across Switzerland and characterized their mountainous landscape using downscaled historical climate data. We sampled 387 trees from 19 populations and genotyped them at 374 single-nucleotide polymorphisms (SNPs) to estimate their...

Data from: Profile of and risk factors for post-stroke cognitive impairment in diverse ethno-regional groups

Jessica W Lo, John D Crawford, David W Desmond, Olivier Godefroy, Hanna Jokinen, Simin Mahinrad, Hee-Joon Bae, Sebastian Köhler, Elles Douven, Julie Staals, Christopher Chen, Xin Xu, Eddie J Chong, Rufus O Akinyemi, Rajesh N Kalaria, Adesola Ogunniyi, Mélanie Barbay, Martine Roussel, Byung-Chul Lee, Velandai K Srikanth, Christopher Moran, Nagaendran Kandiah, Russell J Chander, Behnam Sabayan, J. Wouter Jukema … & Perminder S Sachdev
OBJECTIVE: To address the variability in prevalence estimates and inconsistencies in potential risk factors for post-stroke cognitive impairment (PSCI) using a standardised approach and individual participant data (IPD) from international cohorts in the STROKOG consortium. METHODS: We harmonised data from thirteen studies based in eight countries. Neuropsychological test scores 2 to 6 months after stroke or TIA and appropriate normative data were used to calculate standardised cognitive domain scores. Domain-specific impairment was based on percentile...

Data from: Gray plumage color is more cryptic than brown in snowy landscapes in a resident color polymorphic bird

Katja Koskenpato, Aleksi Lehikoinen, Carita Lindstedt & Patrik Karell
Camouflage may promote fitness of given phenotypes in different environments. The tawny owl (Strix aluco) is a colour polymorphic species with a grey and brown morph resident in the Western Palearctic. A strong selection pressure against the brown morph during snowy and cold winters has been documented earlier but the selection mechanisms remain unresolved. Here we hypothesise that selection favors the grey morph because it is better camouflaged against predators and mobbers in snowy conditions...

Data from: Climate limitation at the cold edge – contrasting perspectives from species distribution modelling and a transplant experiment

Caroline Greiser, Eric Meineri, Miska Luoto, Kristoffer Hylander & Johan Ehrlén
The role of climate in determining range margins is often studied using species distribution models (SDMs), which are easily applied but have well-known limitations, e.g. due to their correlative nature and colonization and extinction time lags. Transplant experiments can give more direct information on environmental effects, but often cover small spatial and temporal scales. We simultaneously applied an SDM using high-resolution spatial predictors and an integral projection (demographic) model based on a transplant experiment at...

Data from: Scaling up the effects of inbreeding depression from individuals to metapopulations

Etsuko Nonaka, Jukka Sirén, Panu Somervuo, Lasse Ruokolainen, Otso Ovaskainen & Ilkka Hanski
1. Inbreeding is common in nature, and many laboratory studies have documented that inbreeding depression can reduce the fitness of individuals. Demonstrating the consequences of inbreeding depression on the growth and persistence of populations is more challenging because populations are often regulated by density- or frequency-dependent selection and influenced by demographic and environmental stochasticity. A few empirical studies have shown that inbreeding depression can increase extinction risk of local populations. The importance of inbreeding depression...

Data from: Seasonal ecosystem metabolism across shallow benthic habitats measured by aquatic eddy covariance

Karl M. Attard, Ivan F. Rodil, Ronnie N. Glud, Peter Berg, Joanna Norkko & Alf Norkko
This submission consists of 40 eddy covariance datasets collected from six shallow sites in the Baltic Sea over an 18 month period. Hourly fluxes were extracted from the high-density data streams and were used to compute daily rates of benthic metabolism (gross primary production (GPP), respiration (R), and net ecosystem metabolism (NEM); in mmol O2 m-2 d-1). These were converted to C assuming an O2 : C of 1.0 for GPP and R. A description...

Reading Bond Films through the Lens of “Religion”

Teemu Taira
“Religion” has been absent from the study of James Bond films. Similarly, James Bond has been absent from studies on religion and popular culture. This article aims to fill the gap by examining 25 Bond films through the lens of “religion”. The analysis suggests that there are a number of references to “religion” in Bond films, although “religion” is typically not a main topic of the films. Furthermore, there is a detectable pattern in the...

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...

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: 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: 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: 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: 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: 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....
