Data from: Bayesian clustering analyses for genetic assignment and study of hybridization in oaks: effects of asymmetric phylogenies and asymmetric sampling schemes

Charalambos Neophytou
Bayesian clustering methods have been widely used for studying species delimitation and genetic introgression. In order to test the effect of phylogenetic relationships and sampling scheme on the inferred clustering solution and on the performance of Bayesian clustering analysis, I simulated genotypes of the interfertile oak species Quercus robur, Quercus petraea, and Quercus pubescens and I run analyses using two popular software programs, STRUCTURE and BAPS. First, based on purebred simulations, I compared clustering solutions...

Data from: Predictors of Phytophthora diversity and community composition in natural areas across diverse Australian ecoregions

Treena I. Burgess, Keith L. McDougall, Peter M. Scott, Giles E. Hardy, Jeff Garnas & Giles E. StJ. Hardy
Comprehensive understanding of the patterns and drivers of microbial diversity at a landscape scale is in its infancy, despite the recent ease by which soil communities can be characterized using massively parallel amplicon sequencing. Here we report on a comprehensive analysis of the drivers of diversity distribution and composition of the ecologically and economically important Phytophthora genus from 414 soil samples collected across Australia. We assessed 22 environmental and seven categorical variables as potential predictors...

Data from: Unexpected population genetic structure of European roe deer in Poland: an invasion of the mtDNA genome from Siberian roe deer

Maciej Matosiuk, Anetta Borkowska, Magdalena Świsłocka, Paweł Mirski, Zbigniew Borowski, Kamil Krysiuk, Aleksey A. Danilkin, Elena Y. Zvychaynaya, Alexander P. Saveljev & Mirosław Ratkiewicz
Introgressive hybridization is a widespread evolutionary phenomenon which may lead to increased allelic variation at selective-neutral loci and to transfer of fitness-related traits to introgressed lineages. We inferred the population genetic structure of the European roe deer (Capreolus capreolus) in Poland from mitochondrial (CR and cyt b) and sex-linked markers (ZFX, SRY, DBY4 and DBY8). Analyses of CR mtDNA sequences from 452 individuals indicated widespread introgression of Siberian roe deer (C. pygargus) mtDNA in the...

Data from: Incorporating uncertainty into forest management planning: timber harvest, wildfire and climate change in the boreal forest

Colin J. Daniel, Michael T. Ter-Mikaelian, B. Mike Wotton, Bronwyn Rayfield & Marie-Josée Fortin
In an effort to ensure the sustainability of their forests, boreal forest managers often use forest planning models to make future projections of timber supply and other key services, such as habitat for wildlife. Projecting the fate of these services has proven to be challenging, however, as major uncertainties exist regarding the principal drivers of boreal ecosystem dynamics, including the future spatial and temporal distribution of wildfire and timber harvesting. Existing forest planning models are...

Data from: Maternal antibodies contribute to sex based difference in hantavirus transmission dynamics

Eva R. Kallio, Heikki Henttonen, Esa Koskela, Åke Lundkvist, Tapio Mappes, Olli Vapalahti & A. Lundkvist
Individuals often differ in their ability to transmit disease and identifying key individuals for transmission is a major issue in epidemiology. Male hosts are often thought to be more important than females for parasite transmission and persistence. However, the role of infectious females, particularly the transient immunity provided to offspring through maternal antibodies (MatAbs), has been neglected in discussions about sex-biased infection transmission. We examined the effect of host sex upon infection dynamics of zoonotic...

Data from: Contrasting effects of large density changes on relative testes size in fluctuating populations of sympatric vole species

Ines Klemme, Carl D. Soulsbury & Heikki Henttonen
Across species, there is usually a positive relationship between sperm competition level and male reproductive effort on ejaculates, typically measured using relative testes size (RTS). Within populations, demographic and ecological processes may drastically alter the level of sperm competition and thus, potentially affect the evolution of testes size. Here, we use longitudinal records (across 38 years) from wild sympatric Fennoscandian populations of five species of voles to investigate whether RTS responds to natural fluctuations in...

Data from: Transient synchrony among populations of five foliage-feeding Lepidoptera

Maartje J. Klapwijk, Jonathan A. Walter, Aniko Hirka, György Csóka, Christer Björkman & Andrew M. Liebhold
1. Studies of transient population dynamics have largely focused on temporal changes in dynamical behavior, such as the transition between periods of stability and instability. The present study explores a related dynamic pattern, namely transient synchrony during a 49-year period among populations of five sympatric species of forest insects that share host tree resources. The long time-series allows a more comprehensive exploration of transient synchrony patterns than most previous studies. Considerable variation existed in the...

Data from: Long-term species loss and homogenization of moth communities in Central Europe

Anu Valtonen, Aniko Hirka, Levente Szőcs, Matt Ayres, Heikki Roininen & György Csóka
As global biodiversity continues to decline steeply, it is becoming increasingly important to understand diversity patterns at local and regional scales. Changes in land use and climate, nitrogen deposition and invasive species are the most important threats to global biodiversity. Because land use changes tend to benefit a few species but impede many, the expected outcome is generally decreasing population sizes, decreasing species richness at local and regional scales, and increasing similarity of species compositions...

Data from: Spatial genetic analyses reveal cryptic population structure and migration patterns in a continuously harvested grey wolf (Canis lupus) population in north-eastern Europe

Maris Hindrikson, Jaanus Remm, Peep Männil, Egle Tammeleht, Janis Ozolins & Urmas Saarma
Spatial genetics is a relatively new field in wildlife and conservation biology that is becoming an essential tool for unravelling the complexities of animal population processes, and for designing effective strategies for conservation and management. Conceptual and methodological developments in this field are therefore critical. Here we present two novel methodological approaches that further the analytical possibilities of STRUCTURE and DResD. Using these approaches we analyse structure and migrations in a grey wolf (Canis lupus)...

Data from: The importance of individual heterogeneity for interpreting faecal glucocorticoid metabolite levels in wildlife studies

Joy Coppes, Jim-Lino Kämmerle, Mirjam Willert, Annette Kohnen, Rupert Palme & Veronika Braunisch
1. Being a non-invasive and inexpensive method, the analysis of faecal corticosteroid metabolites (FCM) is increasingly being applied in wildlife research. Various environmental factors have been shown to influence FCM levels, but most studies did not account for inter-individual variance, which we hypothesized may substantially affect the results. 2. We combined FCM analysis with genetic analysis to identify the sex and individual of samples collected in three consecutive winters, with repeated samples per individual, across...

Data from: Targeted re-sequencing of five Douglas-fir provenances reveals population structure and putative target genes of positive selection

Thomas Müller, Fabian Freund, Henning Wildhagen & Karl J. Schmid
Douglas-fir (Pseudotsuga menziesii) occurs in a coastal and an interior variety that differ in drought tolerance and other adaptive traits. To characterize genome-wide levels of genetic diversity in coding regions and to identify genes involved in local adaptation, we used targeted sequence capture to re-sequence 72 trees representing one interior and four coastal provenances. A custom NimbleGen sequence capture array was designed from 57,110 putative unique transcripts (PUTs) to enrich genomic sequencing libraries for these...

Data from: Lower body mass and higher metabolic rate enhance winter survival in root voles, Microtus oeconomus

Karol Zub, Zbigniew Borowski, Paulina A. Szafrańska, Monika Wieczorek & Marek Konarzewski
Although the biological significance of individual variation in physiological traits is widely recognized, studies of their association with fitness in wild populations are surprisingly scarce. We investigated the effect of individual phenotypic variation in body mass, resting (RMR) and peak metabolic rates (PMR) on mortality of the root vole Microtus oeconomus. Body mass and metabolic rates varied significantly among consecutive years and were also age dependent, as individuals born in late summer and autumn were...

Data from: Assessment of spatial discordance of primary and effective seed dispersal of European beech (Fagus sylvatica L.) by ecological and genetic methods

Matías Millerón, Unai López De Heredia, Zaida Lorenzo, Jesús Alonso, Aikaterini Dounavi, Luis Gil & Nikos Nanos
Spatial discordance between primary and effective dispersal in plant populations indicates that postdispersal processes erase the seed rain signal in recruitment patterns. Five different models were used to test the spatial concordance of the primary and effective dispersal patterns in a European beech (Fagus sylvatica) population from central Spain. An ecological method was based on classical inverse modelling (SSS), using the number of seed/seedlings as input data. Genetic models were based on direct kernel fitting...

Data from: Predator–vole interactions in northern Europe: the role of small mustelids revised

Katri Korpela, Pekka Helle, Heikki Henttonen, Erkki Korpimäki, Esa Koskela, Otso Ovaskainen, Hannu Pietiäinen, Janne Sundell, Jari Valkama, Otso Huitu, H. Pietiainen & E. Korpimaki
The cyclic population dynamics of vole and predator communities is a key phenomenon in northern ecosystems, and it appears to be influenced by climate change. Reports of collapsing rodent cycles have attributed the changes to warmer winters, which weaken the interaction between voles and their specialist subnivean predators. Using population data collected throughout Finland during 1986–2011, we analyse the spatio-temporal variation in the interactions between populations of voles and specialist, generalist and avian predators, and...

Data from: Secondary successional trajectories of structural and catabolic bacterial communities in oil polluted soil planted with hybrid poplar

Shinjini Mukherjee, Timo Sipilä, Pertti Pulkkinen & Kim Yrjälä
Poplars have widely been used for rhizoremediation of a broad range of organic contaminants for the past two decades. Still, there is a knowledge gap regarding the rhizosphere associated bacterial communities of poplars and their dynamics during the remediation process. It is envisaged that a detailed understanding of rhizosphere associated microbial populations will greatly contribute to a better design and implementation of rhizoremediation. In order to investigate the long-term succession of structural and catabolic bacterial...

Data from: Tournament ABC analysis of the western palaearctic population history of an oak gallwasp, Synergus umbraculus

Graham N. Stone, Sarah C. White, György Csóka, George Melika, Serap Mutun, Zsolt Penzes, Ebrahim S. Sadeghi, Karsten Schonrogge, Majid Tavakoli & James A. Nicholls
Approximate Bayesian computation (ABC) is a powerful and widely used approach in inference of population history. However, the computational effort required to discriminate among alternative historical scenarios often limits the set that is compared to those considered more likely a priori. While often justifiable, this approach will fail to consider unexpected but well-supported population histories. We used a hierarchical tournament approach, in which subsets of scenarios are compared in a first round of ABC analyses...

Data from: Breeding increases the efficacy of Chondrostereum purpureum in the sprout control of birch

Leena Hamberg, Henna Vartiamäki & Jarkko Hantula
We tested whether the pairing of selected isolates could be used to increase the efficiency of a decay fungus Chondrostereum purpureum (Pers. Ex Fr.) Pouzar to control hardwood sprouting in Finland. We paired C. purpureum strains efficient in sprout control or highly active in laccase production, and tested the efficacy of their progeny in spout control experiments. This procedure resulted in a strain with an efficacy superior to that of the parental strains. The mortality...

Data from: Brewing trouble: coffee invasion in relation to edges and forest structure in tropical rainforest fragments of the Western Ghats, India

Atul Arvind Joshi, Divya Mudappa & T. R. Shankar Raman
While the conservation impacts of inva- sive plant species on tropical biodiversity is widely recognised, little is known of the potential for cultivated crops turning invasive in tropical forest regions. In the Western Ghats biodiversity hotspot, India, fragmented rainforests often adjoin coffee plantations. This study in the Anamalai hills assessed the effects of distance from edges and forest structure on the occurrence and abundance of shade-tolerant coffee (Arabica Coffea arabica and Robusta C. canephora) in...

Data from: Species interactions increase the temporal stability of community productivity in Pinus sylvestris-Fagus sylvatica mixtures across Europe

Miren Del Río, Hans Pretzsch, Ricardo Ruiz-Peinado, Evy Ampoorter, Peter Annighöfer, Ignacio Barbeito, Kamil Bielak, Gediminas Brazaitis, Lluis Coll, Lars össler, Marek Fabrika, David I. Forrester, Michael Heym, Václav Hurt, Viktor Kurylyak, Magnus Löf, Fabio Lombardi, Ekaterina Makrickiene, Bratislav Matovic, Frits Mohren, Renzo Motta, Jan Den Ouden, Maciej Pach, Quentin Ponette, Gerhard Schütze … & Lars Drössler
1.There is increasing evidence that species diversity enhances the temporal stability of community productivity in different ecosystems, although its effect at population and tree levels seems to be negative or neutral. Asynchrony in species responses to environmental conditions was found to be one of the main drivers of this stabilizing process. However, the effect of species mixing on the stability of productivity, and the relative importance of the associated mechanisms, remain poorly understood in forest...
