Data from: Dung beetle species interactions and multifunctionality are affected by an experimentally warmed climate

Eleanor M. Slade & Tomas Roslin
While substantial effort has been invested in modelling changes in species distribution with climate change, less attention has been given to how climate warming will affect interactions among co-occurring species, and the cascading functional consequences. In this study, realistic dung beetle communities were subjected to an experimental warming treatment and the net effect on the functions of dung decomposition (in terms of dung mass) and plant productivity (in terms of biomass production of ryegrass grown...

Data from: Short-term climate change manipulation effects do not scale up to long-term legacies: effects of an absent snow cover on boreal forest plants

Gesche Blume-Werry, Juergen Kreyling, Hjalmar Laudon & Ann Milbau
1. Despite time lags and non-linearity in ecological processes, the majority of our knowledge about ecosystem responses to long-term changes in climate originates from relatively short-term experiments. 2. We utilized the longest ongoing snow removal experiment in the world and an additional set of new plots at the same location in northern Sweden to simultaneously measure the effects of long-term (11 winters) and short-term (1 winter) absence of snow cover on boreal forest understorey plants,...

Data from: Intensity of space use reveals conditional sex-specific effects of prey and conspecific density on home range size

Malin Aronsson, Matthew Low, José V. López-Bao, Jens Persson, John Odden, John D C. Linnell & Henrik Andrén
Home range (HR) size variation is often linked to resource abundance, with sex differences expected to relate to sex-specific fitness consequences. However, studies generally fail to disentangle the effects of the two main drivers of HR size variation, food and conspecific density, and rarely consider how their relative influence change over spatiotemporal scales. We used location data from 77 Eurasian lynx (Lynx lynx) from a 16-year Scandinavian study to examine HR sizes variation relative to...

Data from: Hypoxic areas, density-dependence and food limitation drive the body condition of a heavily exploited marine fish predator

Michele Casini, Filip Käll, Martin Hansson, Maris Plikshs, Tatjana Baranova, Olle Karlsson, Karl Lundström, Stefan Neuenfeldt, Anna Gardmark & Joakim Hjelm
Investigating the factors regulating fish condition is crucial in ecology and the management of exploited fish populations. The body condition of cod (Gadus morhua) in the Baltic Sea has dramatically decreased during the past two decades, with large implications for the fishery relying on this resource. Here, we statistically investigated the potential drivers of the Baltic cod condition during the past 40 years using newly compiled fishery-independent biological data and hydrological observations. We evidenced a...

Data from: Establishment of a refined oral glucose tolerance test in pigs, and assessment of insulin, glucagon and glucagon-like peptide-1 responses

Elin Manell, Patricia Hedenqvist, Anna Svensson & Marianne Jensen-Waern
Diabetes mellitus is increasing worldwide and reliable animal models are important for progression of the research field. The pig is a commonly used large animal model in diabetes research and the present study aimed to refine a model for oral glucose tolerance test (OGTT) in young growing pigs, as well as describing intravenous glucose tolerance test (IVGTT) in the same age group. The refined porcine OGTT will reflect that used in children and adolescents. Eighteen...

Data from: Disentangling associational effects: both resource density and resource frequency affect search behaviour in complex environments

Thomas A. Verschut, Paul G. Becher, Peter Anderson & Peter A. Hambäck
Neighbouring resources have been found to either decrease or increase the likelihood that a consumer organism attacks a focal resource. These phenomena are referred to as associational resistance (AR) and associational susceptibility (AS), respectively. While associational effects have been observed in various field studies, little is known on how resource heterogeneity can cause associational effects. We used a laboratory approach in which we studied the effects of resource density and frequency in the search behaviour...

Data from: Consequences for piglet performance of group housing lactating sows at one, two, or three weeks post-farrowing

Ola Thomsson, Ylva Sjunnesson, Ulf Magnusson, Lena Eliasson-Selling, Anna Wallenbeck & Ann-Sofi Bergqvist
Housing lactating sows with piglets in a multi-suckling pen from around 14 days post-farrowing is common practice in Swedish organic piglet production. However, nursing-suckling interaction is less frequent in multi-suckling pens than in individual farrowing pens, thus affecting piglet performance, e.g., piglet growth. Moreover, piglet mortality is higher in systems using multi-suckling pens. Three management routines whereby lactating sows with piglets were moved from individual farrowing pens to multi-suckling pens at one, two, or three...

Data from: Photosynthesis, growth, and decay traits in Sphagnum – a multispecies comparison

Fia Bengtsson, Gustaf Granath & Håkan Rydin
Peat mosses (Sphagnum) largely govern carbon sequestration in Northern Hemisphere peatlands. We investigated functional traits related to growth and decomposition in Sphagnum species. We tested the importance of environment and phylogeny in driving species traits and investigated trade-offs among them. We selected 15 globally important Sphagnum species, representing four sections (subgenera) and a range of peatland habitats. We measured rates of photosynthesis and decomposition in standard laboratory conditions as measures of innate growth and decay...

Data from: An empirical comparison of models for the phenology of bird migration

Andreas Lindén, Kalle Meller & Jonas Knape
Bird migration phenology shows strong responses to climate change. Studies of trends and patterns in phenology are typically based on annual summarizing metrics, such as means and quantiles calculated from raw daily count data. However, with irregularly sampled data and large day-to-day variation, such metrics can be biased and noisy, and may be analysed using phenological functions fitted to the data. Here we use count data of migration passage from a Finnish bird observatory to...

Data from: The ecology of wildlife disease surveillance: demographic and prevalence fluctuations undermine surveillance

Laura Walton, Glenn Marion, Ross S. Davidson, Piran C. L. White, Lesley A. Smith, Dolores Gavier-Widen, Lisa Yon, Duncan Hannant, Michael R. Hutchings & Piran C.L. White
Wildlife disease surveillance is the first line of defence against infectious disease. Fluctuations in host populations and disease prevalence are a known feature of wildlife disease systems. However, the impact of such heterogeneities on the performance of surveillance is currently poorly understood. We present the first systematic exploration of the effects of fluctuations' prevalence and host population size on the efficacy of wildlife disease surveillance systems. In this study, efficacy is measured in terms of...

Data from: A new paradigm for biomonitoring: an example building on the Danish Stream Plant Index

Annette Baattrup-Pedersen, Emma Göthe, Tenna Riis, Dagmar K. Andersen & Søren E. Larsen
Despite intensive efforts for more than a decade to develop Water Framework-compliant assessment systems, shortcomings continue to appear. In particular, the lack of reference conditions has hindered the development of assessment systems capturing the heart of the Water Framework Directive (WFD) – that ecological status should be set as the deviation from the natural, undisturbed condition. Recently, the Danish Stream Plant Index (DSPI) was developed. This system contrasts existing systems in that it builds on...

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...

Data from: The gut microbiota of the pine weevil is similar across Europe and resembles that of other conifer-feeding beetles

Aileen Berasategui, Karolin Axelsson, Göran Nordlander, Axel Schmidt, Anna-Karin Borg-Karlson, Jonathan Gershenzon, Olle Terenius & Martin Kaltenpoth
The pine weevil (Hylobius abietis, Coleoptera: Curculionidae) is an important pest of conifer seedlings in Europe. Despite its economic importance, little is known about the composition of its gut microbial community and the role it plays in mediating the weevil's ability to utilize conifers as a food source. Here, we characterized the gut bacterial communities of different populations of H. abietis across Europe and compared them to those of other beetles that occupy similar ecological...

Data from: Population structure in Atlantic cod in the eastern North Sea-Skagerrak-Kattegat: early life stage dispersal and adult migration

Carl André, Henrik Svedäng, Halvor Knutsen, Geir Dahle, Patrik Jonsson, Anna-Karin Ring, Mattias Sköld & Per Erik Jorde
Background: In marine fish species, where pelagic egg and larvae drift with ocean currents, population structure has been suggested to be maintained by larval retention due to hydrographic structuring and by homing of adult fish to natal areas. Whilst natal homing of adults has been demonstrated for anadromous and coral reef fishes, there are few documented examples of philopatric migration in temperate marine fish species. Results: Here, we demonstrate temporally stable genetic differentiation among spawning...

Data from: What you need is what you eat? Prey selection by the bat Myotis daubentonii

Eero J. Vesterinen, Lasse Ruokolainen, Niklas Wahlberg, Carlos Peña, Tomas Roslin, Veronika N. Laine, Ville Vasko, Ilari E. Sääksjärvi, Kai Norrdahl & Thomas M. Lilley
Optimal foraging theory predicts that predators are selective when faced with abundant prey, but become less picky when prey gets sparse. Insectivorous bats in temperate regions are faced with the challenge of building up fat reserves vital for hibernation during a period of decreasing arthropod abundances. According to optimal foraging theory, prehibernating bats should adopt a less selective feeding behaviour – yet empirical studies have revealed many apparently generalized species to be composed of specialist...

Data from: Comparison of capture and storage methods for aqueous macrobial eDNA using an optimized extraction protocol: advantage of enclosed filter

Johan Spens, Alice R. Evans, David Halfmaerten, Steen W. Knudsen, Mita E. Sengupta, Sarah S. T. Mak, Eva E. Sigsgaard & Micaela Hellström
Aqueous environmental DNA (eDNA) is an emerging efficient non-invasive tool for species inventory studies. To maximize performance of downstream quantitative PCR (qPCR) and next-generation sequencing (NGS) applications, quality and quantity of the starting material is crucial, calling for optimized capture, storage and extraction techniques of eDNA. Previous comparative studies for eDNA capture/storage have tested precipitation and ‘open’ filters. However, practical ‘enclosed’ filters which reduce unnecessary handling have not been included. Here, we fill this gap...

Data from: Human shields mediate sexual conflict in a top predator

Sam M.J.G. Steyaert, Martin Leclerc, Fanie Pelletier, Jonas Kindberg, Sven Brunberg, Jon E. Swenson, Andreas Zedrosser & S. M. J. G. Steyaert
Selecting the right habitat in a risky landscape is crucial for an individual's survival and reproduction. In predator–prey systems, prey often can anticipate the habitat use of their main predator and may use protective associates (i.e. typically an apex predator) as shields against predation. Although never tested, such mechanisms should also evolve in systems in which sexual conflict affects offspring survival. Here, we assessed the relationship between offspring survival and habitat selection, as well as...

Data from: Sensitivity of the farmland bird community to crop diversification in Sweden: does the CAP fit?

Jonas Josefsson, Åke Berg, Matthew Hiron, Tomas Pärt & Sönke Eggers
Crop diversification has been introduced as an environmental strategy in the ‘Greening’ of the EU Common Agricultural Policy (CAP) for 2015–2020. The primary target of crop diversification is soil and ecosystem resilience, but claims for potential benefits for farmland biodiversity are also common. However, understanding of relationships between the number (compositional heterogeneity) and spatial arrangement (configurational heterogeneity) of crop fields and biodiversity is generally poor, making such claims relatively unfounded. In this study, we monitored...

Data from: Prey selection of Scandinavian wolves: single large or several small?

Håkan Sand, Ann Eklund, Barbara Zimmermann, Camilla Wikenros & Petter Wabakken
Research on large predator-prey interactions are often limited to the predators’ primary prey, with the potential for prey switching in systems with multiple ungulate species rarely investigated. We evaluated wolf (Canis lupus) prey selection at two different spatial scales, i.e., inter- and intra-territorial, using data from 409 ungulate wolf-kills in an expanding wolf population in Scandinavia. This expansion includes a change from a one-prey into a two-prey system with variable densities of one large-sized ungulate;...

Data from: Blood does not buy goodwill: allowing culling increases poaching of a large carnivore

Guillaume Chapron & Adrian Treves
Quantifying environmental crime and the effectiveness of policy interventions is difficult because perpetrators typically conceal evidence. To prevent illegal uses of natural resources, such as poaching endangered species, governments have advocated granting policy flexibility to local authorities by liberalizing culling or hunting of large carnivores. We present the first quantitative evaluation of the hypothesis that liberalizing culling will reduce poaching and improve population status of an endangered carnivore. We show that allowing wolf (Canis lupus)...

Data from: The importance of accounting for larval detectability in mosquito habitat-association studies

Matthew Low, Admasu Tassew Tsegaye, Rickard Ignell, Sharon Hill, Rasmus Elleby, Vilhelm Feltelius & Richard Hopkins
Background: Mosquito habitat-association studies are an important basis for disease control programmes and/or vector distribution models. However, studies do not explicitly account for incomplete detection during larval presence and abundance surveys, with potential for significant biases because of environmental influences on larval behaviour and sampling efficiency. Methods: Data were used from a dip-sampling study for Anopheles larvae in Ethiopia to evaluate the effect of six factors previously associated with larval sampling (riparian vegetation, direct sunshine,...

Data from: Different-sized grazers have distinctive effects on plant functional composition of an African savannah

Fons Van Der Plas, Ruth A. Howison, Nokukhanya Mpanza, Joris P. G. M. Cromsigt & Han Olff
Grazing ungulates play a key role in many ecosystems worldwide and can form diverse assemblages, such as in African savannahs. In many of these ecosystems, present-day ungulate communities are impoverished subsets of once diverse assemblages. While we know that excluding all ungulates from grasslands can exert major effects on both the structure and composition of the vegetation, how different individual ungulate species may have contrasting effects on grassland communities remains poorly understood. Here, we performed...

Data from: A cross-continental comparison of plant and beetle responses to retention of forest patches during timber harvest

Susan C. Baker, Charles B. Halpern, Timothy J. Wardlaw, Christel Kern, Graham J. Edgar, Russell J. Thomson, Richard E. Bigley, Jerry F. Franklin, Kamal J.K. Gandhi, Lena Gustafsson, Samuel Johnson, Brian J. Palik, Thomas A. Spies, E. Ashley Steel, Jan Weslien, Joachim Strengbom & Kamal J. K. Gandhi
Timber harvest can adversely affect forest biota. Recent research and application suggest that retention of mature forest elements (‘retention forestry’), including unharvested patches (or ‘aggregates’) within larger harvested units, can benefit biodiversity compared to clearcutting. However, it is unclear whether these benefits can be generalized among the diverse taxa and biomes in which retention forestry is practiced. Lack of comparability in methods for sampling and analysing responses to timber harvest and edge creation presents a...
