Disease data of Triphragmium ulmariae on Filipendula ulmaria in the Skeppsvik archipelago

Jiasui Zhan, Lars Ericson, Jose González-Jiménez & Jeremy Burdon
The data set provides information on the incidence, prevalence and severity of a rust fungus Triphragmium ulmariae occurring in populations of the herbaceous perennial Filipendula ulmaria growing on a range of islands in the Skeppsvik archipelago, northern Sweden. These data, together with information on the size of individual host populations, has been used to monitor the impact of the disease on host population growth rates and temporal and spatial dynamics in a natural plant pathogen...

Resistance mixtures reduce insect herbivory in strawberry (Fragaria vesca) plantings: leaf damage and yield data

Tuuli-Marjaana Koski, Sanne De Jong, Anne Muola, Daniel B. Amby, Erik Andreasson & Johan A. Stenberg
The transition towards more sustainable plant protection with reduced pesticide use is difficult, because there is no ‘silver bullet’ available among non-chemical tools. Integrating several plant protection approaches may thus be needed for efficient pest management. Recently, increasing the genetic diversity of plantations via cultivar mixing has been proposed as a possible method to reduce pest damage. However, previous studies have not addressed either the relative efficiency of exploiting cultivar mixing and intrinsic plant herbivore...

Data from: Traits mediate niches and co-occurrences of forest beetles in ways that differ among bioclimatic regions

Ryan C. Burner, Jörg G. Stephan, Lukas Drag, Tone Birkemoe, Jörg Muller, Tord Snäll, Otso Ovaskainen, Mária Potterf, Juha Siitonen, Olav Skarpaas, Inken Doerfler, Martin M. Gossner, Peter Schall, Wolfgang W. Weisser & Anne Sverdrup-Thygeson
Aim To investigate the role of traits in beetle community assembly and test for consistency in these effects among several bioclimatic regions. We asked (1) whether traits predicted species’ responses to environmental gradients (i.e., their niches), (2) whether these same traits could predict co-occurrence patterns, and (3) how consistent were niches and the role of traits among study regions. Location Boreal forests in Norway and Finland, temperate forests in Germany. Methods We complied capture records...

Data from: Size-dependent sensitivity of stream amphipods indicates population-level responses to chemical pollution

Francis J. Burdon, Anja Taddei & Kajta Räsanen
Global change assessments have typically ignored synthetic chemical pollution, despite the rapid increase of pharmaceuticals, pesticides, and industrial chemicals in the environment. The paucity of research on the ecological effects of these ‘micropollutants’ undermines our efforts to address the freshwater biodiversity crisis. Understanding the responses of individual organisms to chemical pollution can help address this knowledge gap because individual-level effects can cascade across populations, communities, and ecosystems with devastating consequences. Inputs of treated municipal wastewater...

Capturing the dynamics of small populations: A retrospective assessment using long-term data for an island reintroduction

Doug Armstrong, Elizabeth Parlato, Barbara Egli, Wendy Dimond, Åsa Berggren, Mhairi McCready, Kevin Parker & John Ewen
1. The art of population modelling is to incorporate factors essential for capturing a population’s dynamics while otherwise keeping the model as simple as possible. However, it is unclear how optimal model complexity should be assessed, and whether this optimal complexity has been affected by recent advances in modelling methodology. This issue is particularly relevant to small populations because they are subject to complex dynamics but inferences about those dynamics are often constrained by small...

The relative effects of pace of life and habitat characteristics on the evolution of sexual ornaments: a comparative assessment

Will Sowersby, Simon Eckerström-Liedholm, Piotr Rowiński, Julia Balogh, Stefan Eiler, Joseph Upstone, Alejandro Gonzalez-Voyer & Björn Rogell
Selection may favor greater investment into sexual ornaments when opportunities for future reproduction are limited (e.g., due to high adult mortality). However, a key driver of mortality, predation, typically selects against elaborate sexual ornaments. Here, we examine the evolution of sexual ornaments in a group of killifishes, which have marked contrasts in life-history strategy between species and inhabit environments that differ in their accessibility to aquatic predators. We first assessed if the size of sexual...

Recreation and hunting differentially affect deer behaviour and sapling performance.

Bjorn Mols, Bjorn Mols, Evert Lambers, Joris Cromsigt, Dries Kuijper & Christian Smit
Humans are increasingly acknowledged as apex predators that shape landscapes of fear to which herbivores adapt their behaviour. Here, we investigate how humans modify deer space-use and their effects on vegetation at two spatial scales; zones with different types of human use (large-scale risk factor) and, nested within that, trails (fine-scale risk factor). In zones with three contrasting types of human activities: (1) no recreation, no hunting, (2) with recreation, no hunting, and (3) with...

Moose habitat selection under the landscape of predation risk

Håkan Sand, Mark Jamieson, Henrik Andrén, Camilla Wikenros, Joris Cromsigt & Johan Månsson
Landscape of fear refers to the spatial variation in prey perception of predation risk, that under certain conditions, may lead to changes in their behavior. Behavioral responses of prey in relation to large carnivore predation risk have mainly been conducted in areas with low anthropogenic impact. We used long-term data on the distribution of moose in different habitat types in a system characterized by intensive management of all three trophic levels (silviculture, harvest of wolves...

Data from: Unravelling hybridization in Phytophthora using phylogenomics and genome size estimation

Kris Van Poucke, Annelies Haegeman, Thomas Goedefroit, Fran Focquet, Leen Leus, Marília Horta Jung, Corina Junker, Miguel Redondo, Claude Husson, Kaloyan Kostov, Aneta Lyubenova, Petya Christova, Anne Chandelier, Slavcho Slavov, Arthur De Cock, Peter Bonants, Sabine Werres, Jonàs Palau, Benoit Marçais, Thomas Jung, Jan Stenlid, Tom Ruttink & Kurt Heungens
The genus Phytophthora comprises many economically and ecologically important plant pathogens. Hybrid species have previously been identified in at least six of the 12 phylogenetic clades. These hybrids can potentially infect a wider host range and display enhanced vigour compared to their progenitors. Phytophthora hybrids therefore pose a serious threat to agriculture as well as to natural ecosystems. Early and correct identification of hybrids is therefore essential for adequate plant protection but this is hampered...

Genomic data from: Are you ready for the heat? Phenotypic plasticity vs adaptation of heat tolerance in three-spined stickleback

Giovanna Mottola, María-Eugenia López, Anti Vasemägi, Mikko Nikinmaa & Katja Anttila
Heat waves constitute a challenge for aquatic ectotherms. However, the thermal tolerance of animals and their individual phenotypic plasticity to respond to heat waves may be influenced by thermal history. We tested these hypotheses by comparing the upper thermal tolerance and the individual capacities of three-spined sticklebacks from populations with different thermal histories to respond to heat waves. Two populations originated from thermally polluted nuclear power plant (NPP) habitats, while four locations represented geographically adjacent...

Data from: Context matters: the landscape matrix determines the population genetic structure of temperate forest herbs across Europe

Tobias Naaf, Jannis Till Feigs, Siyu Huang, Jörg Brunet, Sara A. O. Cousins, Guillaume Decocq, Pieter De Frenne, Martin Diekmann, Sanne Govaert, Per-Ola Hedwall, Jonathan Lenoir, Jaan Liira, Camille Meeussen, Jan Plue, Pieter Vangansbeke, Thomas Vanneste, Kris Verheyen, Stephanie I. J. Holzhauer & Katja Kramp
Context. Plant populations in agricultural landscapes are mostly fragmented and their functional connectivity often depends on seed and pollen dispersal by animals. However, little is known about how the interactions of seed and pollen dispersers with the agricultural matrix translate into gene flow among plant populations. Objectives. We aimed to identify effects of the landscape structure on the genetic diversity within, and the genetic differentiation among, spatially isolated populations of three temperate forest herbs. We...

Links between boreal forest management, soil fungal communities and belowground carbon sequestration

Karolina Jörgensen, Gustaf Granath, Joachim Strengbom & Björn Lindahl
Forest management has a potential to alter belowground carbon storage. However, the underlying mechanisms, and the relative importance of carbon input and decomposition in regulation of soil carbon dynamics are poorly understood. We examined whether interactive effects of forest fertilization and thinning on carbon stocks in the topsoil of boreal forests were linked to changes in fungal community composition, biomass, and enzyme activities, in a long-term fertilization and thinning experiment distributed across 29 Pinus sylvestris...

Bryosphere loss impairs litter decomposition consistently across moss species, litter types, and micro-arthropod abundance

Roger Grau-Andrés, David A. Wardle & Paul Kardol
The bryosphere (i.e., ground mosses and their associated biota) is a key driver of nutrient and carbon dynamics in many terrestrial ecosystems, in part because it regulates litter decomposition. However, we have a poor understanding of how litter decomposition responds to changes in the bryosphere, including changes in bryosphere cover, moss species, and bryosphere-associated biota. Specifically, the contribution of micro-arthropods to litter decomposition in the bryosphere is unclear. Here, we used a 16-month litterbag field...

Data from: Direct and indirect effects of landscape and field management intensity on carabids through trophic resources and weeds

Benjamin Carbonne, David A. Bohan, Hana Foffovà, Eirini Daouti, Britta Frei, Veronika Neidel, Pavel Saska, Jiří Skuhrovec & Sandrine Petit
Carabids are important biological control agents of weeds and other pests in agricultural fields. The carabid community is built upon direct and indirect ecological effects of landscape complexity, field management intensity and biotic components that in interaction make any prediction of community size and composition challenging. We analyse a large-scale sample of 60 European cereal fields using Structural Equation Modelling to quantify the direct effects of field management intensity and the surrounding landscape, and their...

Seasonal release from competition explains partial migration in European moose

Bram Van Moorter, Navinder Singh, Christer Rolandsen, Erling Solberg, Holger Dettki, Jyrki Pusenius, Johan Månsson, Hakan Sand, Jos Milner, Ole Roer, Aimee Tallian, Wiebke Neumann, Göran Ericsson & Atle Mysterud
Partial migration, whereby a proportion of a population migrates between distinct seasonal ranges, is common throughout the animal kingdom. However, studies linking existing theoretical models of migration probability, with empirical data are lacking. The competitive release hypothesis for partial migration predicts that due to density-dependent habitat selection, the proportion of migrants increases as the relative quality and size of the seasonal range increases, but decreases with increasing migration cost and population density. To test this...

Macronutritional composition of Swedish moose rumen samples collected 2014/15

Annika Felton, Hilde Wam, Adam Felton, Stephen Simpson, Caroline Stolter, Per-Ola Hedwall, Jonas Malmsten, Torsten Eriksson, Mulualem Tigabu & David Raubenheimer
At northern latitudes, large spatial and temporal variation in the nutritional composition of available foods poses challenges to wild herbivores trying to satisfy their nutrient requirements. Studies conducted in mostly captive settings have shown that animals from a variety of taxonomic groups deal with this challenge by adjusting the amounts and proportions of available food combinations to achieve a target nutrient balance. In this study, we used proportions-based nutritional geometry to analyse the nutritional composition...

Consequences of migratory coupling of predators and prey when mediated by human actions

Navinder Singh, Frauke Ecke, Todd Katzner, Sumanta Bagchi, Per Sandstöm & Birger Hörnfeldt
Aim: Animal migrations influence ecosystem structure, dynamics, and persistence of predator and prey populations. The theory of migratory coupling postulates that aggregations of migrant prey can induce large-scale synchronized movements in predators, and this coupling is consequential for the dynamics of ecological communities. The degree to which humans influence these interactions remains largely unknown. We tested whether the creation of large resource pulses by humans such as seasonal herding of reindeer Rangifer tarandus and hunting...

Data from: Sensitivity to habitat fragmentation across European landscapes in three temperate forest herbs

Tobias Naaf, Jannis Till Feigs, Siyu Huang, Jörg Brunet, Sara A. O. Cousins, Guillaume Decocq, Pieter De Frenne, Martin Diekmann, Sanne Govaert, Per-Ola Hedwall, Kenny Helsen, Jonathan Lenoir, Jaan Liira, Camille Meeussen, Jan Plue, Pedro Poli, Fabien Spicher, Pieter Vangansbeke, Thomas Vanneste, Kris Verheyen, Stephanie I. J. Holzhauer & Katja Kramp
Context. Evidence for effects of habitat loss and fragmentation on the viability of temperate forest herb populations in agricultural landscapes is so far based on population genetic studies of single species in single landscapes. However, forest herbs differ in their life histories, and landscapes have different environments, structures and histories, making generalizations difficult. Objectives. We compare the response of three slow-colonizing forest herbs to habitat loss and fragmentation and set this in relation to differences...

Data from: Potential of typical highland and mountain forests in the Czech Republic for climate-smart forestry: ecosystem-scale drought responses

Georg Jocher, Natalia Kowalska, Manuel Acosta, Jan Krejza, Irena Marková, John Marshall, Tereza Uchytilová, Marian Pavelka & Michal Marek
Climate-smart forestry (CSF) consists of an extensive framework of actions directed to mitigating and adapting to global climate change impacts on the resilience and productivity of forest ecosystems. The study connected to this data set investigates the impact of the pan-European 2018 drought on carbon exchange dynamics in typical highland and mountain forests in the Czech Republic, including two coniferous (Norway spruce at Bílý Kříž and Rajec) and one deciduous (European beech at Štítná) stand....

Culture performance, gene marker, and transcriptome data for fungal isolates (Chalara longipes, Laccaria bicolor, Serpula lacrymans, and Trichoderma harzianum)

Fahri Hasby, Florian Barbi, Stefano Manzoni & Björn Lindahl
Metatranscriptomics holds the prospect of predicting fungal phenotypes based on patterns of gene expressions, providing new opportunities to obtain information about metabolic processes without disturbance of natural systems, and with taxonomic resolution. Acquisition of fungal metabolic carbon and its subsequent partitioning between biomass production and respiration, i.e. the carbon-use efficiency, are central parameters in biogeochemical modelling. However, current available techniques for estimating these parameters in natural systems are all associated with practical and theoretical shortcomings,...

Disentangling the nonlinear effects of habitat complexity on functional responses

Julien Mocq, Pavel Soukup, Joacim Näslund & David Boukal
1. Structural complexity of habitats modifies trophic interactions by providing refuges and altering predator and prey behaviour. Nonlinear effects on trophic interaction strengths driven by these mechanisms may alter food web dynamics and community structure in response to habitat modifications. However, changes in functional response, the relationship between prey density and feeding rate, along habitat complexity (HC) gradients are little understood. 2. We quantified functional responses along a HC gradient from an entirely unstructured to...

Environmental and seasonal correlates of capercaillie movement traits in a Swedish wind farm

Jim-Lino Kämmerle, Julia Taubmann, Henrik Andrén, Wolfgang Fiedler & Joy Coppes
Animals continuously interact with their environment through behavioural decisions, rendering the appropriate choice of movement speed and directionality an important phenotypic trait. Anthropogenic activities may alter animal behaviour, including movement. A detailed understanding of movement decisions is therefore of great relevance for science and conservation alike. The study of movement decisions in relation to environmental and seasonal cues requires continuous observation of movement behaviour, recently made possible by high-resolution telemetry. We studied movement traits of...

Organic fertilization suppresses aphid growth via carabids in the absence of specialist predators

Guillermo Aguilera Núñez
Biological control by natural enemies is a valuable ecosystem service. The predator community in a crop field is a combination of predators dwelling in the field and those moving into it from the surrounding landscape. The former is mainly affected by field management, the latter more by the composition of the surrounding landscape. Yet, separate and combined effects of local and landscape management on pest suppression have seldom been investigated. We set-up mesocosms within an...

Biochar increases tree biomass in a managed boreal forest, but does not alter N2O, CH4, and CO2 emissions

Roger Grau-Andrés, Melissa RA Pingree, Mats G Öquist, David A Wardle, Marie-Charlotte Nilsson & Michael J Gundale
Biochar soil amendment may provide the forestry sector with a formidable tool to simultaneously sequester carbon (C) in the soil and aboveground by enhancing plant productivity, yet several key uncertainties remain. Crucially, empirical evidence of long-term effects of biochar management on vegetation and on greenhouse gas emissions in forest ecosystems is scarce. Using a large field experiment in a young managed boreal forest in northern Sweden, we investigated the effects of biochar (applied either on...

Variation in developmental rates is not linked to environmental unpredictability in annual killifishes

Piotr Rowinski, Will Sowersby, Joacim Näslund, Simon Eckerström-Liedholm, Karl Gotthard & Björn Rogell
Comparative evidence suggests that adaptive plasticity may evolve as a response to predictable environmental variation. However, less attention has been placed on unpredictable environmental variation, which is considered to affect evolutionary trajectories by increasing phenotypic variation (or bet-hedging). Here, we examine the occurrence of bet-hedging in egg developmental rates in seven species of annual killifish that originate from a gradient of variation in precipitation rates, under three treatment incubation temperatures (21°C, 23°C, and 25°C). In...
