Metaschoepite dissolution in sediment column systems – groundwater/soil geochemistry and uranium X-ray spectroscopy data

W. Bower, K. Morris, F.R. Livens, J.F.W. Mosselmans, C.M. Fallon, A.J. Fuller, L.S. Natrajan, C. Boothman, J.R. Lloyd, S. Utsunomia, D. Grolimund, D. Ferreira Sanchez, T. Jilbert, J.E. Parker, T. Neill & G. Law
This dataset contains the results of a laboratory study investigating the dissolution of UO3•nH2O particles in dynamic sediment/groundwater column systems, representative of the shallow subsurface at the Sellafield Ltd. site, UK. Measurements were carried out to determine the extent of uranic particle dissolution and the speciation of dissolved uranium within the columns under contrasting biogeochemical conditions (oxic and electron-donor amended). Columns effluents were analysed periodically for key biogeochemical indicators (nitrate, sulfate) and trace metals (iron,...

Supporting data for Formation of Highly Oxidized Molecules from NO3 Radical Oxidation of Δ-3-Carene: A Computational Mechanism

Danielle Draper, Nanna Myllys, Noora Hyttinen, Kristian Moller, Henrik Kjaergaard, Juliane Fry, James Smith & Theo Kurten
NO3 radical oxidation of most monoterpenes is a significant source of secondary organic aerosol (SOA) in many regions influenced by both biogenic and anthropogenic emissions, but there are very few published mechanistic studies of NO3 chemistry beyond simple 1st generation products. Here, we present a computationally-derived mechanism detailing the unimolecular pathways available to the 2nd generation of peroxy radicals following NO3 oxidation of Δ-3-carene, defining generations based on the sequence of peroxy radicals formed rather...

Data from: Predator co-evolution and prey trait variability determine species coexistence

Thomas Scheuerl, Johannes Cairns, Lutz Becks & Teppo Hiltunen
Predation is one of the key ecological mechanisms allowing species coexistence and influencing biological diversity. However, ecological processes are subject to contemporary evolutionary change, and the degree to which predation affects diversity ultimately depends on the interplay between evolution and ecology. Furthermore, ecological interactions that influence species co-existence can be altered by reciprocal co-evolution especially in the case of antagonistic interactions such as predation or parasitism. Here we used an experimental evolution approach to test...

Data from: A phylogenomic perspective to diversity, hybridization and evolutionary affinities in the stickleback genus Pungitius

Guo Baocheng, Fang Bohao, Shikano Takahito, Momigliano Paolo, Wang Cui, Kravchenko Alexandra & Merilä Juha
Hybridization and convergent evolution are phenomena of broad interest in evolutionary biology, but their occurrence poses challenges for reconstructing evolutionary affinities among affected taxa. Sticklebacks in the genus Pungitius are a case in point: evolutionary relationships and taxonomic validity of different species and populations in this circumpolarly distributed species complex remain contentious due to convergent evolution of traits regarded as diagnostic in their taxonomy, and possibly also due to frequent hybridization among taxa. To clarify...

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: The possible role of ant larvae in the defence against social parasites

Unni Pulliainen, Heikki Helanterä, Liselotte Sundstrom & Eva Schultner
Temporary social parasite ant queens initiate new colonies by entering colonies of host species, where they begin laying eggs. As the resident queen can be killed during this process, host colonies may lose their entire future reproductive output. Selection thus favours the evolution of defence mechanisms, before and after parasite intrusion. Most studies on social parasites focus on host worker discrimination of parasite queens and their offspring. However, ant larvae can also influence brood composition...

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: 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...

Explaining illness with evil: Pathogen prevalence fosters moral vitalism

Brock Bastian, Christin-Melanie Vauclair, Steve Loughnan, Paul Bain, Ashwini Ashokkumar, Maja Becker, Michal Bilewicz, Emma Collier-Baker, Carla Crespo, Paul W. Eastwick, Ronald Fischer, Malte Friese, Ángel Gómez, Valeschka M. Guerra, Jose Luis Castellanos Guevara, Katja Hanke, Nic Hooper, Li-Li Huang, Shi Junqi, Minoru Karasawa, Peter Kuppens, Siri Leknes, Müjde Peker, Cesar Pelay, Afoditi Pina … & William B. Swann
Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in Studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on...

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: 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: 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: 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...

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...

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: 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: 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: 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: 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...

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...

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...
