Data from: Egg morphology fails to identify nests parasitized by conspecifics in common pochard: a test based on protein fingerprinting and including female relatedness

Adéla Petrželková, Hannu Pöysä, Petr Klvaňa, Tomáš Albrecht & David Hořák
Conspecific brood parasites lay eggs in nests of other females of the same species. A variety of methods have been developed and used to detect conspecific brood parasitism (CBP). Traditional methods may be inaccurate in detecting CBP and in revealing its true frequency. On the other hand more accurate molecular methods are expensive and time consuming. Eadie developed a method for revealing CBP based on differences in egg morphology. That method is based on Euclidean...

Data from: Genome-wide analyses suggest parallel selection for universal traits may eclipse local environmental selection in a highly mobile carnivore

Astrid Vik Stronen, Bogumiła Jędrzejewska, Cino Pertoldi, Ditte Demontis, Ettore Randi, Magdalena Niedziałkowska, Tomasz Borowik, Vadim E. Sidorovich, Josip Kusak, Ilpo Kojola, Alexandros A. Karamanlidis, Janis Ozolins, Vitalii Dumenko & Sylwia D. Czarnomska
Ecological and environmental heterogeneity can produce genetic differentiation in highly mobile species. Accordingly, local adaptation may be expected across comparatively short distances in the presence of marked environmental gradients. Within the European continent, wolves (Canis lupus) exhibit distinct north–south population differentiation. We investigated more than 67-K single nucleotide polymorphism (SNP) loci for signatures of local adaptation in 59 unrelated wolves from four previously identified population clusters (northcentral Europe n = 32, Carpathian Mountains n =...

Data from: Sex-dependent dominance at a single locus maintains variation in age at maturity in salmon

Nicola J. Barson, Tuku Aykanat, Kjetil Hindar, Matthew Baranski, Geir H. Bolstad, Peder Fiske, Céleste Jacq, Arne J. Jensen, Susan E. Johnston, Sten Karlsson, Matthew Kent, Thomas Moen, Eero Niemelä, Torfinn Nome, Tor F. Næsje, Panu Orell, Atso Romakkaniemi, Harald Sægrov, Kurt Urdal, Jaakko Erkinaro, Sigbjørn Lien & Craig R. Primmer
Males and females share many traits that have a common genetic basis; however, selection on these traits often differs between the sexes, leading to sexual conflict. Under such sexual antagonism, theory predicts the evolution of genetic architectures that resolve this sexual conflict. Yet, despite intense theoretical and empirical interest, the specific loci underlying sexually antagonistic phenotypes have rarely been identified, limiting our understanding of how sexual conflict impacts genome evolution and the maintenance of genetic...

Data from: Food limitation constrains host immune responses to nematode infections

Kristian M. Forbes, Tapio Mappes, Tarja Sironen, Tomas Strandin, Peter Stuart, Seppo Meri, Olli Vapalahti, Heikki Henttonen & Otso Huitu
Trade-offs in the allocation of finite-energy resources among immunological defences and other physiological processes are believed to influence infection risk and disease severity in food-limited wildlife populations. However, this prediction has received little experimental investigation. Here we test the hypothesis that food limitation impairs the ability of wild field voles (Microtus agrestis) to mount an immune response against parasite infections. We conducted a replicated experiment on vole populations maintained in large outdoor enclosures during boreal...

Data from: Gene flow from domesticated escapes alters the life history of wild Atlantic salmon

Geir H. Bolstad, Kjetil Hindar, Grethe Robertsen, Bror Jonsson, Harald Sægrov, Ola H. Diserud, Peder Fiske, Arne J. Jensen, Kurt Urdal, Tor F. Næsje, Bjørn T. Barlaup, Bjørn Florø-Larsen, Håvard Lo, Eero Niemelä & Sten Karlsson
Interbreeding between domesticated and wild animals occurs in several species. This gene flow has long been anticipated to induce genetic changes in life-history traits of wild populations, thereby influencing population dynamics and viability. Here, we show that individuals with high levels of introgression (domesticated ancestry) have altered age and size at maturation in 62 wild Atlantic salmon Salmo salar populations, including seven ancestral populations to breeding lines of the domesticated salmon. This study documents widespread...

Data from: Taxon abundance, diversity, co-occurrence and network analysis of the ruminal microbiota in response to dietary changes in dairy cows

Ilma Tapio, Daniel Fischer, Lucia Blasco, Miika Tapio, R. John Wallace, Ali R. Bayat, Laura Ventto, Minna Kahala, Enyew Negussie, Kevin J. Shingfield & Johanna Vilkki
The effects of sunflower oil (SO) (0 or 50 g/kg diet dry matter), supplemented to diets contrasting in the proportion of forage and concentrate (FC) (65:35 vs 35:65), were evaluated for their influence on rumen microbiome. Four multiparous Nordic Red dairy cows fitted with rumen cannulae were used in a 4 × 4 Latin square with a 2 × 2 factorial arrangement of treatments and four 35-d periods. Ruminal digesta samples were collected on d...

Data from: Environment and host as large-scale controls of ectomycorrhizal fungi

Sietse Van Der Linde, Laura M. Suz, C. David L. Orme, Filipa Cox, Henning Andreae, Endla Asi, Bonnie Atkinson, Sue Benham, Christopher Carroll, Nathalie Cools, Bruno De Vos, Hans-Peter Dietrich, Johannes Eichhorn, Joachim Germann, Tine Grebenc, Hyun S. Gweon, Karin Hansen, Frank Jacob, Ferdinand Kristöfel, Pawel Lech, Miklos Manninger, Jan Martin, Henning Meesenburg, Päivi Merilä, Manuel Nicolas … & Martin I. Bidartondo
Explaining the large-scale diversity of soil organisms that drive biogeochemical processes—and their responses to environmental change—is critical. However, identifying consistent drivers of belowground diversity and abundance for some soil organisms at large spatial scales remains problematic. Here we investigate a major guild, the ectomycorrhizal fungi, across European forests at a spatial scale and resolution that is—to our knowledge—unprecedented, to explore key biotic and abiotic predictors of ectomycorrhizal diversity and to identify dominant responses and thresholds...

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: A meta-analysis on nitrogen retention by buffer zones

Elena Valkama, Kirsi Usva, Merja Saarinen & Jaana Uusi-Kämppä
Buffer zones, established between agricultural fields and water bodies, are widely used as a measure to reduce nitrogen (N) in surface runoff and groundwater. However, the literature indicates inconsistent results on the N removal efficiency of buffer zones between studies. We performed a weighed meta-analysis on the buffer zone effects on nitrate-N and total N in surface runoff and groundwater by summarizing 46 studies published between 1980 and 2017. The overall effects of buffer zones...

Data from: Genetic evidence of female kin clusters in a continuous population of a solitary carnivore, the Eurasian lynx

Katja Holmala, Annika Herrero, Alexander Kopatz, Julia Schregel, Hans G. Eiken & Snorre B. Hagen
Large terrestrial carnivores can sometimes display strong family bonds affecting the spatial distribution of related individuals. We studied the spatial genetic relatedness and family structure of female Eurasian lynx, continuously distributed in southern Finland. We hypothesized that closely related females form matrilineal assemblages, clustering together with relatives living in the neighboring areas. We evaluated this hypothesis using tissue samples of 133 legally harvested female lynx (from year 2007 to 2015), genotyped with 23 microsatellite markers,...

Data from: Reliable wolf-dog hybrid detection in Europe using a reduced SNP panel developed for non-invasively collected samples

Jenni Harmoinen, Alina Von Thaden, Jouni Aspi, Laura Kvist, Berardino Cocchiararo, Anne Jarausch, Andrea Gazzola, Teodora Sin, Hannes Lohi, Marjo Hytönen, Ilpo Kojola, Astrid Vik Stronen, Romolo Caniglia, Federica Mattucci, Marco Galaverni, Raquel Godinho, Aritz Ruiz-González, Ettore Randi, Violeta Muñoz-Fuentes & Carsten Nowak
Background: Understanding the processes that lead to hybridization of wolves and dogs is of scientific and management importance, particularly over large geographical scales, as wolves can disperse great distances. However, a method to efficiently detect hybrids in routine wolf monitoring is lacking. Microsatellites offer only limited resolution due to the low number of markers showing distinctive allele frequencies between wolves and dogs. Moreover, calibration across laboratories is time-consuming and costly. In this study, we selected...

Recent changes in mountain birch forest structure and understory vegetation depend on the seasonal timing of reindeer grazing

Sari Stark, Henni Ylänne & Jouko Kumpula
1. Subarctic forest-tundra ecotones dominated by mountain birch (Betula pubescens ssp. czerepanovii) is an important habitat for semi-domestic reindeer (Rangifer tarandus). The seasonal timing of reindeer grazing may direct vegetation trajectories in these systems, because in the summer ranges, mountain birches are subjected to browsing, while in the winter ranges, reindeer feed on understorey vegetation and arboreal lichens but leave the mountain birches intact. 2. Based on earlier research, we predicted that (1) summer browsing...

Urbanization extends flight phenology and leads to local adaptation of seasonal plasticity in Lepidoptera

Thomas Merckx, Matthew Nielsen, Janne Heliölä, Mikko Kuussaari, Lars Pettersson, Juha Pöyry, Juha Tiainen, Karl Gotthard & Sami Kivelä
Urbanization is globally gaining force and challenges biodiversity but has recently also emerged as an agent of evolutionary change. Seasonal phenology and life-cycle regulation are essential processes that urbanization is likely to alter through both the urban-heat-island effect (UHI) and artificial-light-at-night (ALAN). However, how UHI and ALAN affect the evolution of seasonal adaptations has received little attention. Here, we test for urban evolution of seasonal life-history plasticity, specifically changes in the photoperiodic induction of diapause...

Genomics of humic adaptation in Eurasian perch (Perca fluviatilis): SNP genotypes of 32 perch individuals, supplementary figures and tables

Mikhail Ozerov, Kristina Noreikiene, Siim Kahar, Magnus Huss, Ari Huusko, Toomas Kõiv, Margot Sepp, María López, Anna Gårdmark, Riho Gross & Anti Vasemägi
Extreme environments are inhospitable to the majority of species, but some organisms are able to survive in such hostile conditions due to evolutionary adaptations. For example, modern bony fishes have colonized various aquatic environments, including perpetually dark, hypoxic, hypersaline and toxic habitats. Eurasian perch (Perca fluviatilis) is among the few fish species of northern latitudes that is able to live in very acidic humic lakes. Such lakes represent almost “nocturnal” environments; they contain high levels...

Data from: Host developmental stage effects on parasite resistance and tolerance

Ines Klemme, Paul Vincent Debes, Craig Robert Primmer, Laura Härkönen, Jaakko Erkinaro, Pekka Hyvärinen & Anssi Karvonen
Hosts can defend themselves against parasites by either preventing or limiting infections (resistance), or limiting parasite-induced damage (tolerance). However, it remains underexplored how these defense types vary over host development with shifting patterns of resource allocation priorities. Here, we studied the role of developmental stage on resistance and tolerance in Atlantic salmon (Salmo salar). This anadromous fish has distinct life stages related to living in fresh and sea water. We experimentally exposed one-year old salmon,...

Data from: Sediments and flow have mainly independent effects on multitrophic stream communities and ecosystem functions

Kaisa-Riikka Mustonen, Heikki Mykrä, Pauliina Louhi, Annamari Markkola, Mikko Tolkkinen, Ari Huusko, Nico Alioravainen, Sirkku Mäkinen, Timo Muotka & Sirkku Lehtinen
Stream ecosystems are affected by multiple abiotic stressors, and species responses to simultaneous stressors may differ from those predicted based on single-stressor responses. Using 12 semi-natural stream channels, we examined the individual and interactive effects of flow level (low or high flow) and addition of fine sediments (grain size < 2mm) on key ecosystem processes (leaf breakdown, algal biomass accrual) and benthic macroinvertebrate and fungal communities. Both stressors had mostly independent effects on biological responses,...

Data from: Genetic diversity and genomic signatures of selection among cattle breeds from Siberia, eastern and northern Europe

Terhi Iso-Touru, Miika Tapio, Johanna Vilkki, Tatyana Kiseleva, Innokentyi Ammosov, Zoya Ivanova, Ruslan Popov, Mikhail Ozerov & Juha Kantanen
Domestication in the near eastern region had a major impact on the gene pool of humpless taurine cattle (Bos taurus). As a result of subsequent natural and artificial selection, hundreds of different breeds have evolved, displaying a broad range of phenotypic traits. Here, 10 Eurasian B. taurus breeds from different biogeographic and production conditions, which exhibit different demographic histories and have been under artificial selection at various intensities, were investigated using the Illumina BovineSNP50 panel...

Data from: Differences in endophyte communities of introduced trees depend on the phylogenetic relatedness of the receiving forest

Michael J. Gundale, Juan P. Almeida, Håkan Wallander, David A. Wardle, Paul Kardol, Marie-Charlotte Nilsson Hegethorn, Alex Fajardo, Anibal Pauchard, Duane A. Peltzer, Seppo Ruotsalainen, Bill Mason, Nicholas Rosenstock & Marie-Charlotte Nilsson
Plant species sometimes perform extraordinarily well when introduced to new environments, through achieving higher growth rates, individual biomasses or higher densities in their receiving communities compared to their native range communities. One hypothesis proposed to explain enhanced performance in species’ new environments is that their soil microbial communities may be different and provide greater benefit than microbial communities encountered in species’ native environments. However, detailed descriptions of soil biota associated with species in both their...

Data from: Accumulation rates and sources of external nitrogen in decaying wood in a Norway spruce dominated forest

Katja T. Rinne, Tiina Rajala, Krista Peltoniemi, Janet Chen, Aino Smolander & Raisa Mäkipää
Microbial respiration in dead wood contributes substantially to the long-lived forest carbon (C) pool and has a significant role in the forest nitrogen (N) cycle. Wood N content has been found to increase during the decay process; however, temporal dynamics and the sources of this external N remain unclear. To examine N dynamics at various stages of decomposition, we combined high variety of analytical methods on Norway spruce logs, including wood δ15N, N%, 14C-dating, fungal...

Data from: Origins of cattle on Chirikof Island, Alaska, elucidated from genome-wide SNP genotypes

Jared E. Decker, Jeremy F. Taylor, Leeson J. Alexander, Juha Kantanen, Ann Millbrooke, Robert D. Schnabel & Michael D. MacNeil
Feral livestock may harbor genetic variation of commercial, scientific, historical or esthetic value. The origins and uniqueness of feral cattle on Chirikof Island, Alaska, are uncertain. The island is now part of the Alaska Maritime Wildlife Refuge and Federal wildlife managers want grazing to cease, presumably leading to demise of the cattle. Here we characterize the cattle of Chirikof Island relative to extant breeds and discern their origins. Our analyses support the inference that Yakut...

Data from: Inter-annual variation and long-term trends in proportions of resident individuals in partially migratory birds

Kalle Meller, Anssi V Vähätalo, Tatu Hokkanen, Jukka Rintala, Markus Piha & Aleksi Lehikoinen
Partial migration – a part of a population migrates and another part stays resident year-round on the breeding site – is probably the most common type of migration in the animal kingdom, yet it has only lately garnered more attention. Theoretical studies indicate that in partially migratory populations, the proportion of resident individuals (PoR) should increase in high latitudes in response to the warming climate, but empirical evidence exists for few species. We provide the...

Data from: What data to use for forest conservation planning? A comparison of coarse open and detailed proprietary forest inventory data in Finland

Joona A. Lehtomäki, Sakari Tuominen, Tuuli Toivonen, Antti Leinonen & Joona Lehtomäki
The boreal region is facing intensifying resource extraction pressure, but the lack of comprehensive biodiversity data makes operative forest conservation planning difficult. Many countries have implemented forest inventory schemes and are making extensive and up-to-date forest databases increasingly available. Some of the more detailed inventory databases, however, remain proprietary and unavailable for conservation planning. Here, we investigate how well different open and proprietary forest inventory data sets suit the purpose of conservation prioritization in Finland....

Data from: The changing contribution of top-down and bottom-up limitation of mesopredators during 220 years of land use and climate change

Marianne Pasanen-Mortensen, Bodil Elmhagen, Harto Linden, Roger Bergström, Märtha Wallgren, Ype Van Der Velde, Sara A. O. Cousins & Sara A.O. Cousins
Apex predators may buffer bottom-up driven ecosystem change, as top-down suppression may dampen herbivore and mesopredator responses to increased resource availability. However, theory suggests that for this buffering capacity to be realized, the equilibrium abundance of apex predators must increase. This raises the question: will apex predators maintain herbivore/mesopredator limitation, if bottom-up change relaxes resource constraints? Here, we explore changes in mesopredator (red fox Vulpes vulpes) abundance over 220 years in response to eradication and...

Data from: Socio-economic impact classification of alien taxa (SEICAT)

Sven Bacher, Tim M. Blackburn, Franz Essl, Piero Genovesi, Jaakko Heikkilä, Jonathan M. Jeschke, Glyn Jones, Reuben Keller, Marc Kenis, Christoph Kueffer, Angeliki F. Martinou, Wolfgang Nentwig, Jan Pergl, Petr Pyšek, Wolfgang Rabitsch, David M. Richardson, Helen E. Roy, Wolf-Christian Saul, Riccardo Scalera, Montserrat Vila, John R. U. Wilson, Sabina Kumschick & Sabrina Kumschick
Many alien taxa are known to cause socio-economic impacts by affecting the different constituents of human well-being (security; material and non-material assets; health; social, spiritual and cultural relations; freedom of choice and action). Attempts to quantify socio-economic impacts in monetary terms are unlikely to provide a useful basis for evaluating and comparing impacts of alien taxa because they are notoriously difficult to measure and important aspects of human well-being are ignored. Here, we propose a...

Data from: Do environmental conditions experienced in early life affect recruitment age and performance at first breeding in common goldeneye females?

Hannu Pöysä, Robert G. Clark, Antti Paasivaara & Pentti Runko
Environmental conditions experienced early in life may have long-term impacts on life history traits and reproductive performance. We investigated whether ambient temperature experienced during the first two to four weeks of life and weather severity during the first two winters affected recruitment age and relative timing of breeding in the year of recruitment in female common goldeneyes (Bucephala clangula). Our sample consisted of 141 female recruits hatched in a study population in central Finland between...
