Data from: Subsidy type and quality determine direction and strength of trophic cascades in arthropod food web in agro‐ecosystems

Laura G. A. Riggi & Riccardo Bommarco
1. The subsidy hypothesis states that communities receiving nutrient subsidies will demonstrate top-down trophic cascades where predators indirectly increase plant biomass. This has been both confirmed and refuted, which might depend on whether the subsidy has mainly targeted the plant or the detrital food-web compartment, and on the subsidy quality. This is particularly poorly understood for terrestrial communities such as heavily subsidized agroecosystems. 2. Using cages covering 4 m2 of ground in a long-term agricultural...

Data from: Linking plant genes to insect communities: identifying the genetic bases of plant traits and community composition

Hilary L. Barker, Jennifer F. Riehl, Carolina Bernhardsson, Kennedy Rubert-Nason, Liza Holeski, Pär K. Ingvarsson & Richard L. Lindroth
Community genetics aims to understand the effects of intraspecific genetic variation on community composition and diversity, thereby connecting community ecology with evolutionary biology. Thus far, research has shown that plant genetics can underlie variation in the composition of associated communities (e.g., insects, lichen, endophytes), and those communities can therefore be considered as extended phenotypes. This work, however, has been conducted primarily at the plant genotype level and has not identified the key underlying genes. To...

Host plant phenology, insect outbreaks and herbivore communities – The importance of timing

Adam Ekholm, Ayco J. M. Tack, Pertti Pulkkinen & Tomas Roslin
1. Climate change may alter the dynamics of outbreak species by changing the phenological synchrony between herbivores and their host plants. As host plant phenology has a genotypic component that may interact with climate, infestation levels among genotypes might change accordingly. When the outbreaking herbivore is active early in the season, its infestation levels may also leave a detectable imprint on herbivores colonizing the plant later in the season. 2. In this study, we first...

Data from: Trophic interactions and abiotic factors drive functional and phylogenetic structure of vertebrate herbivore communities across the Arctic tundra biome

James D.M. Speed, Ina A. Skjelbred, Isabel C. Barrio, Michael D. Martin, Dominique Berteaux, C. Guillermo Bueno, Katie S. Christie, Bruce C. Forbes, Jennifer Forbey, Daniel Fortin, Jon-Arvid Grytnes, Katrine S. Hoset, Nicolas Lecomte, Bryndis Marteinsdottir, Jesper B. Mosbacher, Åshild O. Pedersen, Virve Ravolainen, Eileen C. Rees, Anna Skarin, Natalya Sokolova, Andrew H. Thornhill, Ingunn Tombre & Eeva M. Soininen
Communities are assembled from species that evolve or colonise a given geographic region, and persist in the face of abiotic conditions and interactions with other species. The evolutionary and colonisation histories of communities are characterised by phylogenetic diversity, while functional diversity is indicative of abiotic and biotic conditions. The relationship between functional and phylogenetic diversity infers whether species functional traits are divergent (differing between related species) or convergent (similar among distantly related species). Biotic interactions...

Data from: Carbon use efficiency of mycorrhizal fungal mycelium increases during the growing season but decreases with forest age across a Pinus sylvestris chronosequence

Andreas Hagenbo, David Hadden, Karina E. Clemmensen, Achim Grelle, Stefano Manzoni, Meelis Mölder, Alf Ekblad & Petra Fransson
1. In boreal forest soils, mycelium of mycorrhizal fungi is pivotal for regulating soil carbon (C) cycling and storage. The carbon use efficiency (CUE), a key parameter in C cycling models, can inform on the partitioning of C between microbial biomass, and potential soil storage, and respiration. Here we test the dependency of mycorrhizal mycelial CUE on stand age and seasonality in managed boreal forest stands. 2. Based on mycelial production and respiration estimates, derived...

Data from: Exploring a Pool-seq only approach for gaining population genomic insights in non-model species

Sara Kurland, Chris Wheat, Maria De La Paz Celorio-Mancera, Verena Kutschera, Jason Hill, Anastasia Andersson, Carl Johan Rubin, Leif Andersson, Nils Ryman & Linda Laikre
Developing genomic insights is challenging in non-model species for which resources are often scarce and prohibitively costly. Here, we explore the potential of a recently established approach using Pool-seq data to generate a de novo genome assembly for mining exons, upon which Pool-seq data is used to estimate population divergence and diversity. We do this for two pairs of sympatric populations of brown trout (Salmo trutta); one naturally sympatric set of populations and another pair...

Data from: Mechanisms of trophic niche compression: evidence from landscape disturbance

Francis J. Burdon, Angus R. McIntosh & Jon S. Harding
1. Natural and anthropogenic disturbances commonly alter patterns of biodiversity and ecosystem functioning. However, how networks of interacting species respond to these changes remains poorly understood. We described aquatic food webs using invertebrate and fish community composition, functional traits, and stable isotopes from twelve agricultural streams along a landscape disturbance gradient. 2. We predicted that excessive deposition of fine inorganic sediment (sedimentation) associated with agricultural activities would negatively influence aquatic trophic diversity (e.g., reduced vertical...

Distribution patterns of fungal taxa and inferred functional traits reflect the non-uniform vertical stratification of soil microhabitats in a coastal pine forest

Kerri Kluting, Karina Clemmensen, Stanislovas Jonaitis, Rimvydas Vasaitis, Sara Holmström, Roger Finlay & Anna Rosling
In boreal systems, soil profiles typically consist of distinct stratified horizons, with organic layers at the surface overlying deeper mineral horizons providing microhabitat variation along a depth gradient, and vertical stratification of fungal communities along such soil profiles is commonly observed. We studied fungal community structure in a coastal pine forest along a gradient of decreasing influence from the coast. In this system, the vertical stratification pattern of soil microhabitats (defined here as organic, mineral...

Accuracy of genomic selection for growth and wood quality traits in two control-pollinated progeny trials using exome capture as genotyping platform in Norway spruce

Zhi-Qiang Chen, John Baison, Jin Pan, Johan Westin, Maria Rosario Garcia Gil & Harry X. Wu
A genomic selection (GS) study of growth and wood quality traits is reported based on control-pollinated Norway spruce families established in two Northern Swedish trials at two locations using exome capture as a genotyping platform. Non-additive effects including dominance and first-order epistatic interactions (including additive-by-additive, dominance-by-dominance, and additive-by-dominance) and marker-by-environment interaction (MxE) effects were dissected in genomic and phenotypic selection models. GS models partitioned additive and non-additive genetic variances more precisely than pedigree-based models. In...

Data from: Fear of the dark? contrasting impacts of humans vs lynx on diel activity of roe deer across Europe

Nadège C. Bonnot, Ophélie Couriot, Anne Berger, Francesca Cagnacci, Simone Ciuti, Johannes De Groeve, Benedikt Gehr, Marco Heurich, Petter Kjellander, Max Kröschel, Nicolas Morellet, Leif Sönnichsen & A.J. Mark Hewison
Humans, as super predators, can have strong effects on wildlife behaviour, including profound modifications of diel activity patterns. Subsequent to the return of large carnivores to human-modified ecosystems, many prey species have adjusted their spatial behaviour to the contrasting landscapes of fear generated by both their natural predators and anthropogenic pressures. The effects of predation risk on temporal shifts in diel activity of prey, however, remain largely unexplored in human-dominated landscapes. We investigated the influence...

Data from: Genetic dissection of complex behaviour traits in German Shepherd dogs

Juliane Friedrich, Erling Strandberg, Per Arvelius, Enrique Sánchez-Molano, Ricardo Pong-Wong, John M. Hickey, Marie J. Haskell & Pamela Wiener
A favourable genetic structure and diversity of behavioural features highlights the potential of dogs for studying the genetic architecture of behaviour traits. However, behaviours are complex traits, which have been shown to be influenced by numerous genetic and non-genetic factors, complicating their analysis. In this study, the genetic contribution to behaviour variation in German Shepherd dogs (GSDs) was analysed using genomic approaches. GSDs were phenotyped for behaviour traits using the established Canine Behavioral Assessment and...

Genomic relatedness and diversity of Swedish native cattle breeds

Maulik Upadhyay, Susanne Eriksson, Sofia Mikko, Erling Strandberg, Hans Stålhammar, Martien AM Groenen, Richard PMA Crooijmans, Göran Andersson & Anna M Johansson
Background Native cattle breeds are important genetic resources given their adaptation to the local environment in which they are bred. However, the widespread use of commercial cattle breeds has resulted in a marked reduction in population size of several native cattle breeds worldwide. Therefore, conservation management of native cattle breeds requires urgent attention to avoid their extinction. To this end, we genotyped nine Swedish native cattle breeds with genome-wide 150K single nucleotide polymorphisms (SNPs) to...

Data from: Factors influencing plasticity in the arrival-breeding interval in a migratory species reacting to climate change

Matthew Low, Debora Arlt, Jonas Knape, Tomas Pärt & Meit Öberg
Climate change is profoundly affecting the phenology of many species. In migratory birds, there is evidence for advances in their arrival time at the breeding ground and their timing of breeding, yet empirical studies examining the interdependence between arrival and breeding time are lacking. Hence, evidence is scarce regarding how breeding time may be adjusted via the arrival-breeding interval to help local populations adapt to local conditions or climate change. We used long-term data from...

David L. Strayer, Boris V. Adamovich, Rita Adrian, David C. Aldridge, Csilla Balogh, Lyubov E. Burlakova, Hannah B. Fried-Petersen, László G.‐Tóth, Amy L. Hetherington, Thomas S. Jones, Alexander Y. Karatayev, Jacqueline B. Madill, Oleg A. Makarevich, J. Ellen Marsden, Andre L. Martel, Dan Minchin, Thomas F. Nalepa, Ruurd Noordhuis, Timothy J. Robinson, Lars G. Rudstam, Astrid N. Schwalb, David R. Smith, Alan D. Steinman & Jonathan M. Jeschke
Dreissenid mussels (including the zebra mussel Dreissena polymorpha and the quagga mussel D. rostriformis) are among the world's most notorious invasive species, with large and widespread ecological and economic effects. However, their long‐term population dynamics are poorly known, even though these dynamics are critical to determining impacts and effective management. We gathered and analyzed 67 long‐term (>10 yr) data sets on dreissenid populations from lakes and rivers across Europe and North America. We addressed five...

This dataset constains information on population counts in experimental populations of Plodia interpunctella (Pyralidae; Hübner) and the parasitoid wasp Venturia canescens (Ichneumonidae; Gravenhorst). The data was collected from a multi-generation microcosm experiment carried out to characterise the combined effects of daily stochastic temperature fluctuations and resource degradation on population responses in the Plodia-Venturia host-parasitoid trophic interaction. The population count data include the weekly total numbers of dead adult hosts and parasitoids and the numbers of...

Data from: Spatial variability in a plant-pollinator community across a continuous habitat: high heterogeneity in the face of apparent uniformity

Sara Reverté, Jordi Bosch, Xavier Arnan, Tomas Roslin, Constanti Stefanescu, J. A. Calleja, Roberto Molowny-Horas, Carlos Hernández-Castellano & Anselm Rodrigo
Large-scale spatial variability in plant-pollinator communities (e.g., along geographic gradients, across different landscapes) is relatively well understood. However, we know much less about how these communities vary at small scales within a uniform landscape. Plants are sessile and highly sensitive to microhabitat conditions, whereas pollinators are highly mobile and, for the most part, display generalist feeding habits. Therefore, we expect plants to show greater spatial variability than pollinators. We analysed the spatial heterogeneity of a...

Long-term warming affects ecosystem functioning through species turnover and intraspecific trait variation

Tiina Salo, Johanna Mattila & Johan Eklöf
Effects of climate change on natural ecosystems can be mediated by ecological processes, but also by rapid evolutionary adaptations and/or non-heritable trait changes in organisms. So far, most studies testing the importance of inter- vs. intraspecific changes for how communities and their functioning responds to climate change are either short-term laboratory experiments in highly controlled (artificial) environments, or long-term field surveys suffering from lack of experimental manipulation. Here, we quantified how community composition and functioning...

Catchment properties and the photosynthetic trait composition of freshwater plant communities

Lars Lønsmann Iversen, A. Winkel, L. Baastrup-Spohr, A. B. Hinke, J. Alahuhta, A. Baattrup-Pedersen, S. Birk, P. Brodersen, P. A. Chambers, F. Ecke, T. Feldmann, D. Gebler, J. Heino, T. S. Jespersen, S. J. Moe, T. Riis, L. Sass, O. Vestergaard, S. C. Maberly, K. Sand-Jensen & O. Pedersen
Unlike in land plants, photosynthesis in many aquatic plants relies on bicarbonate in addition to carbon dioxide (CO2) to compensate for the low diffusivity and potential depletion of CO2 in water. Concentrations of bicarbonate and CO2 vary greatly with catchment geology. In this study, we investigate whether there is a link between these concentrations and the frequency of freshwater plants possessing the bicarbonate use trait. We show, globally, that the frequency of plant species with...

Insects reared out from logging residues on clear cuts in southern Sweden

Mats Jonsell
Growing interest in harvesting logging residues for energy production will reduce the amount of fine (small-diameter) wood. This could pose a threat to saproxylic (dead-wood living) organisms. Therefore, we asked firstly if logging residues have a beetle fauna of conservation interest, and secondly which differences there are between different categories of logging residues. Samples of logging-residue wood of aspen, birch, oak and spruce, divided into three diameter classes ranging between 1 and 15 cm were...

Data from: Bryophyte community composition and diversity are indicators of hydrochemical and ecological gradients in temperate kettle hole mires in Ohio, USA

Roger Grau-Andrés, G. Matt Davies, Camilo Rey-Sanchez & Julie Slater
Peatlands are subject to increased pressure from environmental and land-use change, particularly in temperate regions such as the US Midwest. Bryophytes dominate the ground cover of peatlands and play a key role in their functioning. Effective management and restoration of degraded peatlands requires good understanding of their bryophyte communities, and how these are shaped by environmental conditions. Furthermore, bryophytes are sensitive indicators of environmental conditions. We monitored microhabitat characteristics (hydrology, hydrochemistry, abundance of vascular vegetation,...

Presence-absence sampling for estimating plant density using survey data with variable plot size

Göran Ståhl, Magnus Ekström, Jonas Dahlgren, Per-Anders Esseen, Anton Grafström & Bengt Jonsson
1. Presence-absence sampling is an important method for monitoring state and change of both individual plant species and communities. With this method only the presence or absence of the target species is recorded on plots and thus the method is straightforward to apply and less prone to surveyor judgment compared to other vegetation monitoring methods. However, in the basic setting all plots must be equally large or otherwise it is unclear how data should be...

Data from: Relationships between plant traits, soil properties and carbon fluxes differ between monocultures and mixed communities in temperate grassland

Jonathan R. De Long, Benjamin G. Jackson, Anna Wilkinson, William J. Pritchard, Simon Oakley, Kelly E. Mason, Jörg G. Stephan, Nicholas J. Ostle, David Johnson, Elizabeth M. Baggs & Richard D. Bardgett
1. The use of plant traits to predict ecosystem functions has been gaining growing attention. Aboveground plant traits, such as leaf nitrogen (N) content and specific leaf area (SLA), have been shown to strongly relate to ecosystem productivity, respiration, and nutrient cycling. Further, increasing plant functional trait diversity has been suggested as a possible mechanism to increase ecosystem carbon (C) storage. However, it is uncertain whether belowground plant traits can be predicted by aboveground traits,...
