Data from: Pellets of proof: first glimpse of the dietary composition of adult odonates as revealed by metabarcoding of feces

Kari M. Kaunisto, Tomas Roslin, Ilari E. Sääksjärvi & Eero J. Vesterinen
Recent advances in molecular techniques allow us to resolve the diet of unstudied taxa. Odonates are potentially important top-down regulators of many insects. Yet, to date, our knowledge of odonate prey use is based mainly on limited observations of odonates catching or eating their prey. In this study, we examine the potential use of metabarcoding in establishing the diet of three adult odonate species (Lestes sponsa, Enallagma cyathigerum, and Sympetrum danae) at a site in...

Data from: Related herbivore species show similar temporal dynamics

F. Guillaume Blanchet, Tomas Roslin, Masahito T. Kimura, Tea Huotari, Riikka Kaartinen, Sofia Gripenberg & Ayco J. M. Tack
1.Within natural communities, different taxa display different dynamics in time. Why this is the case we do not fully know. This thwarts our ability to predict changes in community structure, which is important for both the conservation of rare species in natural communities and for the prediction of pest outbreaks in agriculture. 2.Species sharing phylogeny, natural enemies and/or life history traits have been hypothesized to share similar temporal dynamics. We operationalized these concepts into testing...

Data from: Advancing Precambrian palaeomagnetism with the PALEOMAGIA and PINT(QPI) databases

Toni H. Veikkolainen, Andrew J. Biggin, Lauri J. Pesonen, David A. Evans & Nicholas A. Jarboe
State-of-the-art measurements of the direction and intensity of Earth’s ancient magnetic field have made important contributions to our understanding of the geology and palaeogeography of Precambrian Earth. The PALEOMAGIA and PINT(QPI) databases provide thorough public collections of important palaeomagnetic data of this kind. They comprise more than 4,100 observations in total and have been essential in supporting our international collaborative efforts to understand Earth's magnetic history on a timescale far longer than that of the...

Data from: Extraordinarily rapid speciation in a marine fish

Paolo Momigliano, Henri Jokinen, Antoine Fraimout, Ann-Britt Florin, Alf Norkko & Juha Merilä
Divergent selection may initiate ecological speciation extremely rapidly. How often and at what pace ecological speciation proceeds to yield strong reproductive isolation is more uncertain. Here, we document a case of extraordinarily rapid speciation associated with ecological selection in the postglacial Baltic Sea. European flounders (Platichthys flesus) in the Baltic exhibit two contrasting reproductive behaviors: pelagic and demersal spawning. Demersal spawning enables flounders to thrive in the low salinity of the Northern Baltic, where eggs...

Data from: Does sex matter? Gender-specific responses to forest fragmentation in Neotropical bats

Ricardo Rocha, Diogo F. Ferreira, Adrià López-Baucells, Fabio Z. Farneda, Joao M.B. Carreiras, Jorge M. Palmeirim & Christoph F. J. Meyer
Understanding the consequences of habitat modification on wildlife communities is central to the development of conservation strategies. However, albeit male and female individuals of numerous species are known to exhibit differences in habitat use, sex-specific responses to habitat modification remain little explored. Here, we used a landscape-scale fragmentation experiment to assess, separately for males and females, the effects of fragmentation on the abundance of Carollia perspicillata and Rhinophylla pumilio, two widespread Neotropical frugivorous bats. We...

Data from: Climate-driven build-up of temporal isolation within a recently formed avian hybrid zone

Päivi Maria Sirkiä, S. Eryn McFarlane, William Jones, David Wheatcroft, Murielle Ålund, Jakub Rybinski & Anna Qvarnstrom
Divergence in the onset of reproduction can act as an important source of reproductive isolation (i.e. allochronic isolation) between co-occurring young species, but evidence for the evolutionary processes leading to such divergence is often indirect. While advancing spring seasons strongly affect the onset of reproduction in many taxa, it remains largely unexplored whether contemporary spring advancement directly affects allochronic isolation between young species. We examined how increasing spring temperatures affected onset of reproduction and thereby...

Data from: Genetic rescue of an endangered domestic animal through outcrossing with closely related breeds: a case study of the Norwegian Lundehund

Astrid V. Stronen, Elina Salmela, BK Baldursdóttir, P Berg, IS Espelien, Kirsi Järvi, Henrik Jensen, TN Kristensen, Claudia Melis, Tommaso Manenti, Hannes Lohi, Cino Pertoldi & Torsten N. Kristensen
Genetic rescue, outcrossing with individuals from a related population, is used to augment genetic diversity in populations threatened by severe inbreeding and extinction. The endangered Norwegian Lundehund dog (henceforth Lundehund) underwent at least two severe bottlenecks in the 1940s and 1960s that each left only five inbred dogs, and the approximately 1500 dogs remaining world-wide today appear to descend from only two individuals. The Lundehund has a high prevalence of a gastrointestinal disease, to which...

Data from: Selection on the morphology-physiology-performance nexus: lessons from freshwater stickleback morphs

Sergey Morozov, Tuomas Leinonen, Juha Merilä, R.J. Scott McCairns & R. J. Scott McCairns
Conspecifics inhabiting divergent environments frequently differ in morphology, physiology and performance, but the interrelationships amongst traits and with Darwinian fitness remains poorly understood. We investigated population differentiation in morphology, metabolic rate and swimming performance in three-spined sticklebacks (Gasterosteus aculeatus L.), contrasting a marine/ancestral population with two distinct freshwater morphotypes derived from it: the ‘typical’ low-plated morph, and a unique ‘small-plated’ morph. We test the hypothesis that similar to plate loss in other freshwater populations, reduction...

Data from: Safety of single low-dose primaquine in glucose-6-phosphate dehydrogenase deficient falciparum-infected African males: two open-label, randomized, safety trials

Guido Bastiaens, Alfred B. Tiono, Joseph Okebe, Helmi Pett, Sam A. Coulibaly, Bronner P. Gonçalves, Muna Affara, Alphonse Ouédraogo, Edith C. Bougouma, Guillaume S. Sanou, Issa Nébié, John Bradley, Kjerstin H. W. Lanke, Mikko Niemi, Sodiomon B. Sirima, Umberto D'Alessandro, Teun Bousema, Chris Drakeley, Guido J. H. Bastiaens, Helmi E. Pett & Umberto D’Alessandro
Background: Primaquine (PQ) actively clears mature Plasmodium falciparum gametocytes but in glucose-6-phosphate dehydrogenase deficient (G6PDd) individuals can cause hemolysis. We assessed the safety of low-dose PQ in combination with artemether-lumefantrine (AL) or dihydroartemisinin-piperaquine (DP) in G6PDd African males with asymptomatic P. falciparum malaria. Methods and findings: In Burkina Faso, G6PDd adult males were randomized to treatment with AL alone (n = 10) or with PQ at 0.25 (n = 20) or 0.40 mg/kg (n =...

Data from: Assessing the dynamics of natural populations by fitting individual based models with approximate Bayesian computation

Jukka Sirén, Luc Lens, Laurence Cousseau & Otso Ovaskainen
1. Individual based models (IBMs) allow realistic and flexible modelling of ecological systems, but their parametrization with empirical data is statistically and computationally challenging. Approximate Bayesian computation (ABC) has been proposed as an efficient approach for inference with IBMs, but its applicability to data on natural populations has not been yet fully explored. 2. We construct an IBM for the metapopulation dynamics of a species inhabiting a fragmented patch network, and develop an ABC method...

Data from: Breeding bird species diversity across gradients of land use from forest to agriculture in Europe

Matti J. Koivula, Dan E. Chamberlain, Robert J. Fuller, Stephen C. F. Palmer, Attila Bankovics, Fintan Bracken, Tom Bolger, Eduardo De Juana, Marc Montadert, Renato Neves, Rui Rufino, Angel Sallent, Luís Lopes Da Silva, Pedro J. Leitão, Manfred Steffen & Allan D. Watt
Loss, fragmentation and decreasing quality of habitats have been proposed as major threats to biodiversity world-wide, but relatively little is known about biodiversity responses to multiple pressures, particularly at very large spatial scales. We evaluated the relative contributions of four landscape variables (habitat cover, diversity, fragmentation and productivity) in determining different components of avian diversity across Europe. We sampled breeding birds in multiple 1-km2 landscapes, from high forest cover to intensive agricultural land, in eight...

Data from: Insights into the genetic architecture of morphological traits in two passerine bird species

Catarina N. S. Silva, S. Eryn McFarlane, Ingerid J. Hagen, Lars Rönnegård, Anna M. Billing, Thomas Kvalnes, Petri Kemppainen, Bernt Rønning, Thor Harald Ringsby, Bernt-Erik Sæther, Anna Qvarnström, Hans Ellegren, Henrik Jensen & Arild Husby
Knowledge about the underlying genetic architecture of phenotypic traits is needed to understand and predict their evolutionary dynamics. The number of causal loci, magnitude of their effects and location in the genome is however still largely unknown. Here we use genome-wide SNP data from two large-scale datasets on house sparrows and collared flycatchers to examine the genetic architecture of different morphological traits (tarsus length, wing length, body mass, bill depth, bill length, total and visible...

Data from: The importance of species identity and interactions on multifunctionality depends on how ecosystem functions are valued

Eleanor M. Slade, Laura Kirwin, Thomas Bell, Christopher D. Philipson, Owen T. Lewis & Tomas Roslin
Studies investigating how biodiversity affects ecosystem functioning increasingly focus on multiple functions measured simultaneously (‘multifunctionality’). However, few such studies assess the role of species interactions, particularly under alternative environmental scenarios, despite interactions being key to ecosystem functioning. Here we address five questions of central importance to ecosystem multifunctionality using a terrestrial animal system: 1) Does the contribution of individual species differ for different ecosystem functions?; 2) Do inter-species interactions affect the delivery of single functions...

Data from: Wind conditions and geography shape the first outbound migration of juvenile honey buzzards and their distribution across sub-Saharan Africa

Wouter M. G. Vansteelant, Jaana Kekkonen & Patrik Byholm
Contemporary tracking studies reveal that low migratory connectivity between breeding and non-breeding ranges is common in migrant landbirds. It is unclear, however, how internal factors and early-life experiences of individual migrants shape the development of their migration routes and concomitant population-level non-breeding distributions. Stochastic wind conditions and geography may determine whether and where migrants end up by the end of their journey. We tested this hypothesis by satellite-tagging 31 fledgling honey buzzards Pernis apivorus from...

Data from: High-throughput sequencing of transposable element insertions suggests adaptive evolution of the invasive Asian Tiger Mosquito towards temperate environments

Clément Goubert, Hélène Henri, Guillaume Minard, Claire Valiente Moro, Patrick Mavingui, Cristina Vieira & Matthieu Boulesteix
Invasive species represent unique opportunities to evaluate the role of local adaptation during colonization of new environments. Among these species, the Asian tiger mosquito, Aedes albopictus, is a threatening vector of several human viral diseases, including dengue and chikungunya, and raises concerns about the Zika fever. Its broad presence in both temperate and tropical environments has been considered the reflection of great “ecological plasticity.” However, no study has been conducted to assess the role of...

Data from: Global biogeographic patterns in bipolar moss species

Elisabeth Machteld Biersma, Jennifer A. Jackson, Jaakko Hyvonen, Satu Koskinen, Katrin Linse, Howard Griffiths & Peter Convey
A bipolar disjunction is an extreme, yet common, biogeographic pattern in non-vascular plants, yet its underlying mechanisms (vicariance or long-distance dispersal), origin and timing remain poorly understood. Here, combining a large-scale population dataset and multiple dating analyses, we examine the biogeography of four bipolar Polytrichales mosses, common to the Holarctic (temperate and polar Northern Hemisphere regions) and the Antarctic region (Antarctic, sub-Antarctic, southern South America) and other Southern Hemisphere (SH) regions. Our data reveal contrasting...

Data from: Maternal effects in vulnerability to eye-parasites and correlations between behaviour and parasitism in juvenile Arctic charr

Raine Kortet, Tiina Lautala, Jukka Kekäläinen, Jouni Taskinen & Heikki Hirvonen
Hatchery-reared fish show high mortalities after release to the wild environment. Explanations for this include potentially predetermined genetics, behavioural and physiological acclimation to fish farm environments, and increased vulnerability to predation and parasitism in the wild. We studied vulnerability to Diplostomum spp. parasites (load of eye-flukes in the lenses), immune defence (relative spleen size) and anti-predator behaviours (approaches toward predator odour, freezing, and swimming activity) in hatchery-reared juvenile Arctic charr (Salvelinus alpinus) using a nested...

W. Sun, L. M. J. Kooijmans, K. Maseyk, H. Chen, I. Mammarella, T. Vesala, J. Levula, H. Keskinen & U. Seibt
This is the dataset (ver. 2017.02.13) for the manuscript "Soil fluxes of carbonyl sulfide (COS), carbon monoxide, and carbon dioxide in a boreal forest in southern Finland" submitted to the journal Atmospheric Chemistry and Physics.

Data from: Low heritability of nest construction in a wild bird

Pauliina Järvinen, Edward Kluen & Jon E. Brommer
In birds and other taxa, nest construction varies considerably between and within populations. Such variation is hypothesized to have an adaptive (i.e. genetic) basis, but estimates of heritability in nest construction are largely lacking. Here, we demonstrate with data collected over 10 years of 1010 nests built by blue tits in nest boxes that nest size (height of nest material) and nest composition (proportion of feathers in the nest) are repeatable but only weakly (12-13%)...

Data from: A meta-analysis of nestedness and turnover components of beta diversity across organisms and ecosystems

Janne Soininen, Jani Heino & Jianjun Wang
The number of studies investigating the nestedness and turnover components of beta diversity has increased substantially, but our general understanding of the drivers of turnover and nestedness remains elusive. Here, we examined the effects of species traits, spatial extent, latitude and ecosystem type on the nestedness and turnover components of beta diversity. From the 99 studies that partition total beta diversity into its turnover and nestedness components, we assembled 269 and 259 data points for...

Data from: De novo assembly of genomes from long sequence reads reveals uncharted territories of Propionibacterium freudenreichii

Paulina Deptula, Pia K. Laine, Richard J. Roberts, Olli-Pekka Smolander, Helena Vihinen, Vieno Piironen, Lars Paulin, Eija Jokitalo, Kirsi Savijoki, Petri Auvinen & Pekka Varmanen
Background: Propionibacterium freudenreichii is an industrially important bacterium granted the Generally Recognized as Safe (the GRAS) status, due to its long safe use in food bioprocesses. Despite the recognized role in the food industry and in the production of vitamin B12, as well as its documented health-promoting potential, P. freudenreichii remained poorly characterised at the genomic level. At present, only three complete genome sequences are available for the species. Results: We used the PacBio RS...

Data from: Oxygen and carbon isoscapes for the Baltic Sea: testing their applicability in fish migration studies

Jyrki Torniainen, Anssi Lensu, Pekka J. Vuorinen, Eloni Sonninen, Marja Keinänen, Roger I. Jones, William P. Patterson & Mikko Kiljunen
Conventional tags applied to individuals have been used to investigate animal movement, but these methods require tagged individuals be recaptured. Maps of regional isotopic variability known as “isoscapes” offer potential for various applications in migration research without tagging wherein isotope values of tissues are compared to environmental isotope values. In this study, we present the spatial variability in oxygen (math formula) and dissolved inorganic carbon (δ13CDIC) isotope values of Baltic Sea water. We also provide...

Data from: The evolutionary dynamics of adaptive virginity, sex-allocation and altruistic helping in haplodiploid animals

Petri Rautiala, Heikki Helantera & Mikael Puurtinen
In haplodiploids, females can produce sons from unfertilized eggs without mating. However, virgin reproduction is usually considered to be a result of a failure to mate, rather than an adaptation. Here we build an analytical model for evolution of virgin reproduction, sex-allocation, and altruistic female helping in haplodiploid taxa. We show that when mating is costly (e.g. when mating increases predation risk), virginity can evolve as an adaptive female reproductive strategy. Furthermore, adaptive virginity results...

Data from: Intestinal Ralstonia pickettii augments glucose intolerance in obesity

Shanthadevi Udayappan, Petia Kovatcheva-Datchary, Guido Bakker, Stefan Havik, Hilde Herrema, Patrice Cani, Kristien Bouter, Clara Belzer, Julia J. Witjes, Anne Vrieze, Eleonore Susanne Victoria De Sonnaville, Alice Chaplin, Daniel Van Raalte, Steven Aalvink, Geesje Dallinga-Thie, Hans Heilig, Goran Bergstrom, Suzan Van Der Meij, Bart Van Wagensveld, Joost Hoekstra, Frits Holleman, Erik Stroes, Albert Groen, Fredrik Backhed, Willem De Vos … & Daniel H. Van Raalte
An altered intestinal microbiota composition has been implicated in the pathogenesis of metabolic disease including obesity and type 2 diabetes mellitus (T2DM). Low grade inflammation, potentially initiated by the intestinal microbiota, has been suggested to be a driving force in the development of insulin resistance in obesity. Here, we report that bacterial DNA is present in mesenteric adipose tissue of obese but otherwise healthy human subjects. Pyrosequencing of bacterial 16S rRNA genes revealed that DNA...

Data from: Serum copeptin and neuron specific enolase are markers of neonatal distress and long-term neurodevelopmental outcome

Dorottya Kelen, Csilla Andorka, Miklós Szabó, Aleksander Alafuzoff, Kai Kaila & Milla Summanen
The objective of this study was to evaluate the early changes in serial serum levels of copeptin and neuron-specific enolase (NSE) in neonates diagnosed with birth asphyxia, and to determine whether these biomarkers measured in the first 168 hours after birth are predictive of long-term neurodevelopmental outcome. Copeptin and NSE levels were measured from serum samples collected 6, 12, 24, 48, 72, and 168 hours after birth from 75 term neonates diagnosed with hypoxic-ischemic encephalopathy...
