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: Widespread hybridization within mound-building wood ants in Southern Finland results in cytonuclear mismatches and potential for sex-specific hybrid breakdown

Jack Beresford, Marianne Elias, Lucy Pluckrose, Liselotte Sundström, Roger K. Butlin, Pekka Pamilo & Jonna Kulmuni
Hybridization and gene flow between diverging lineages is increasingly recognized as a common evolutionary process and its consequences can vary from hybrid breakdown to adaptive introgression. We have previously found a population of wood ant hybrids between Formica aquilonia and F. polyctena that shows antagonistic effects of hybridization: females with introgressed alleles show hybrid vigour, whereas males with the same alleles show hybrid breakdown. Here we investigate whether hybridization is a general phenomenon in this...

Data from: Local demographic and epidemiological patterns in the Linum marginale – Melampsora lini association – a multi-year study

Hanna Susi, Peter H. Thrall, Luke G. Barrett & Jeremy J. Burdon
1.Many theoretical and empirical studies operate from an assumption that pathogens have a significant influence on the fecundity and lifespan of their host species. However, there is surprisingly little data investigating the long-term fitness impacts and genetic consequences that arise from pathogen infection in natural populations. Here, we address this gap through the analysis of a dataset investigating the local population dynamics of a native host plant (Linum marginale) and an associated rust pathogen (Melampsora...

Data from: Template for using biological trait groupings when exploring large-scale variation in seafloor multifunctionality

Anna Villnäs, Judi Hewitt, Martin Snickars, Mats Westerbom & Alf Norkko
Understanding large-scale spatial variation in ecosystem properties and associated functionality is key for successful conservation of ecosystems. This study provides a template for how to estimate differences in ecosystem functionality over large spatial scales by using groupings of biological traits. We focus on trait groupings that describe three important benthic ecosystem properties, namely bioturbation, community stability and juvenile dispersal. Recognizing that groups of traits interact and are constrained within an organism, we statistically define important...

Data from: The importance of phytoplankton biomolecule availability for secondary production

Elina T. Peltomaa, Sanni L. Aalto, Kristiina M. Vuorio & Sami J. Taipale
The growth and reproduction of animals is affected by their access to resources. In aquatic ecosystems, the availability of essential biomolecules for filter-feeding zooplankton depends greatly on phytoplankton. Here, we analyzed the biochemical composition, i.e., the fatty acid, sterol and amino acid profiles and concentrations as well as protein, carbon, nitrogen, and phosphorus content of 17 phytoplankton monocultures representing the seven most abundant phytoplankton classes in boreal and sub-arctic lakes. To examine how the differences...

Data from: The more the merrier: conspecific density improves performance of gregarious larvae and reduces susceptibility to a pupal parasitoid

Elena Rosa, Saskya Van Nouhuys & Marjo Saastamoinen
Aggregation can confer advantages in animal foraging, defense and thermoregulation. There is a tight connection between the evolution of insect sociality and a highly effective immune system, presumably to inhibit rapid disease spread in a crowded environment. This connection is less evident for animals that spend only part of their life-cycle in a social environment, such as non-eusocial gregarious insects. Our aim was to elucidate the effects of group living by the gregarious larvae of...

Data from: Monthly microclimate models in a managed boreal forest landscape

Caroline Greiser, Eric Meineri, Miska Luoto, Johan Ehrlén & Kristoffer Hylander
The majority of microclimate studies have been done in topographically complex landscapes to quantify and predict how near-ground temperatures vary as a function of terrain properties. However, in forests understory temperatures can be strongly influenced also by vegetation. We quantified the relative influence of vegetation features and physiography (topography and moisture-related variables) on understory temperatures in managed boreal forests in central Sweden. We used a multivariate regression approach to relate near-ground temperature of 203 loggers...

Data from: Population genetic analysis of a global collection of Fragaria vesca using microsatellite markers

Hrannar Smári Hilmarsson, Timo Hytönen, Sachiko Isobe, Magnus Göransson, Tuomas Toivainen & Jón Hallsteinn Hallsson
The woodland strawberry, Fragaria vesca, holds great promise as a model organism. It not only represents the important Rosaceae family that includes economically important species such as apples, pears, peaches and roses, but it also complements the well-known model organism Arabidopsis thaliana in key areas such as perennial life cycle and the development of fleshy fruit. Analysis of wild populations of A. thaliana has shed light on several important developmental pathways controlling, for example, flowering...

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...
