This is the data set used for the publication Buffering effects of soil seed banks on plant community composition in response to land use and climate, published in the journal Global Ecology and Biogeography. Aim. Climate and land use are key determinants of biodiversity, with past and ongoing changes posing serious threats to global ecosystems. Unlike most other organism groups, plant species can possess dormant life-history stages such as soil seed banks, which may help...

Data from: Fire and grazing controlling a tropical tree line: Effects of long‐term grazing exclusion in Bale Mountains, Ethiopia

Maria Ulrika Johansson & Anders Granström
Aims: Tropical tree lines are often associated with abrupt shifts in vegetation, soils and disturbance regimes, but the underlying mechanisms are poorly understood. We analysed the role of grazing, fuels and fire in maintaining a sharp tree line with flammable heathland above non-flammable forest. Location: Bale Mountains, Ethiopia. Methods: Grazing exclosures, repeated vegetation sampling, soil analyses and burning and sowing experiments along an altitudinal gradient with Hagenia abyssinica forest, Erica trimera forest and Erica heathland;...

Genetic diversity of farmed and wild Rufiji tilapia (Oreochromis urolepis urolepis) populations

Christos Palaiokostas
Rufiji tilapia (Oreochromis urolepis urolepis) is an endemic cichlid in Tanzania. In addition to its importance for biodiversity conservation, Rufiji tilapia is also attractive for farming due to its high growth-rate, salinity tolerance, and the production of all-male hybrids when crossed with Nile tilapia (Oreochromis niloticus). The aim of the current study was to assess the genetic diversity and population structure of both wild and farmed Rufiji tilapia populations in order to inform conservation and...

Evolution of chain migration in an aerial insectivorous bird, the common swift Apus apus

Susanne Akesson, Phil Atkinson, Ana Bermejo, Javier De La Puente, Mauro Ferri, Chris Hewson, Jan Holmgren, Erich Kaiser, Lyndon Kearsley, Raymond Klaassen, Heikki Kolunen, Gittan Matsson, Fausto Minelli, Gabriel Norevik, Hannu Pietiäinen, Navinder J Singh, Fernando Spina, Lukas Viktora & Anders Hedenstrom
Spectacular long-distance migration has evolved repeatedly in animals enabling exploration of resources separated in time and space. In birds, these patterns are largely driven by seasonality, cost of migration, and asymmetries in competition leading most often to leap-frog migration, where northern breeding populations winter furthest to the south. Here we show that the highly aerial common swift Apus apus, spending the non-breeding period on the wing, instead exhibits a rarely-found chain migration pattern, where the...

Data from: Why we should care about movements: Using spatially explicit integrated population models to assess habitat source-sink dynamics

Matthieu Paquet, Debora Arlt, Jonas Knape, Matthew Low, Pär Forslund & Tomas Pärt
1. Assessing the source-sink status of populations and habitats is of major importance for understanding population dynamics and for the management of natural populations. Sources produce a net surplus of individuals (per capita contribution to the metapopulation >1) and will be the main contributors for self-sustaining populations, whereas sinks produce a deficit (contribution < 1). However, making these types of assessments is generally hindered by the problem of separating mortality from permanent emigration, especially when...

Modelled spatiotemporally explicit fish densities at different fisheries management scenarios

Jonas Hentati-Sundberg
Conflicts of interest between resource extraction and conservation are widespread, and negotiating such conflicts or trade-offs is a key issue for ecosystem managers. One such trade-off is resource competition between fisheries and marine top predators. Managing this trade-off has so far been difficult due to a lack of knowledge regarding the amount and distribution of prey required by top predators. Here, we develop a framework that can be used to address this gap: a bio-energetic...

Forest inventory data from Finland and Sweden for: Demographic performance of European tree species at their hot and cold climatic edges, plus ancillary climate data

Sophia Ratcliffe, Jonas Dahlgren, Aleksi Lehtonen, Christian Wirth, Paloma Ruiz-Benito, Miguel A. Zavala, Gerald Kaendler, Raisa Mäkipää & Georges Kunstler
1. Species range limits are thought to result from a decline in demographic performance at range edges. However, recent studies reporting contradictory patterns in species demographic performance at their edges cast doubt on our ability to predict climate change demographic impacts. To understand these inconsistent demographic responses at the edges, we need to shift the focus from geographic to climatic edges and analyse how species responses vary with climatic constraints at the edge and species’...

A large wild salmon stock shows genetic and life history differentiation within, but not between, rivers

Antti Miettinen, Stefan Palm, Johan Dannewitz, Emma Lind, Craig R. Primmer, Atso Romakkaniemi, Johan Östergren & Victoria L. Pritchard
Anadromous salmonid fishes frequently exhibit strong geographic population structuring. However, population genetic differentiation of Atlantic salmon (Salmo salar) at fine geographic scales differs across equivalent spatial extents in different regions. So far, fine-scale genetic differentiation has not been assessed in rivers of the Baltic Sea, a region that contains an evolutionarily distinct Atlantic salmon lineage. Thus, Baltic salmon are currently managed on the river level, without focus on potential genetic structure and diversity within rivers....

Cannot see the diversity for all the species: evaluating inclusion criteria for local species lists when using abundant citizen science data

Alejandro Ruete, Debora Arlt, Åke Berg, Jonas Knape, Michał Żmihorski & Tomas Pärt
Abundant citizen science data on species occurrences is becoming increasingly available and enables identifying composition of communities occurring at multiple sites with high temporal resolution. However, for species displaying temporary patterns of local occurrences, i.e. that are transient to some sites, biodiversity measures are clearly dependent on the criteria used to include species into local species lists. Using abundant opportunistic citizen science data from frequently visited wetlands we investigated the sensitivity of α- and β-diversity...

Effects of plant functional group removal on CO2 fluxes and belowground C stocks across contrasting ecosystems

Roger Grau-Andrés, David Wardle, Michael Gundale, Claire Foster & Paul Kardol
Changes in plant communities can have large effects on ecosystem carbon (C) dynamics and long-term C stocks. However, how these effects are mediated by environmental context or vary among ecosystems is not well understood. To study this, we used a long-term plant removal experiment set up across 30 forested lake islands in northern Sweden which collectively represent a strong gradient of soil fertility and ecosystem productivity. We measured forest floor CO2 exchange and aboveground and...

Data offspring performance following two-donor crosses at different floral stages and with different competitor types in greenhouse studies of Collinsia heterophylla

Åsa Lankinen, Josefin Madjidian, Henrik G. Smith & Stefan Andersson
Data on two offspring performance traits (seeds per capsule and flower number) in greenhouse studies of Collinsia heterophylla to investigate indirect benefits of mate choice. We performed two-donor pollinations during successive floral stages and with different competitor types (outcross and self) to assess how stigma receptivity and two pollen traits known to affect siring success influence offspring performance. We also investigated the link between seed production in mothers and offspring as an indication of heritability...

Data from: Genetic evidence for sexual reproduction and multiple infections of Norway spruce cones by the rust fungus Thekopsora areolata

Hernan Capador, Berit Samils, Juha Kaitera & Ake Olson
Rust fungi are obligate parasites of plants with complex and in many cases poorly known life cycles which may include host alteration and up to five spore types with haploid, diploid and dikaryotic nuclear stages. This study supports that Thekopasora areolata, the causal agent of cherry-spruce rust in Norway spruce, is a macrocyclic heteroecious fungus with all five spore stages which uses two host plants Prunus padus and Picea abies to complete its life cycle....

Central place foraging in a human-dominated landscape - how do common cranes select feeding sites?

Lovisa Nilsson, Jens Persson, Nils Bunnefeld & Johan Månsson
Human infrastructure and disturbance play an important role when animals select resources in human-modified landscapes. Theory predicts that animals trade food intake against costs of movement or disturbance to optimize net energy gain and fitness, but other necessary resources may also constrain the decisions, e.g. when animals repeatedly need to return to a central location, such as a nest, waterhole or night roost. Central place foraging theory states that the probability of occurrence of an...

Unexpectedly diverse forest dung beetle communities in degraded rainforest landscapes in Madagascar

Kaisa Torppa, Helena Wirta & Ilkka Hanski
Tropical forests, which harbor high levels of biodiversity, are being lost at an alarming speed. Madagascar, a biodiversity hotspot, has lost more than half of its original forest cover. Most of the remaining forests are small fragments of primary and secondary forest with differing degrees of human impact. These forests, as well as coffee and fruit plantations, may be important in supporting the forest dependent biodiversity in Madagascar but this has been little studied. In...

Data from: Molecular mapping and identification of quantitative trait loci for domestication traits in field cress (Lepidium campestre L.) genome

Zeratsion Abera Desta, Dirk-Jan De Koning & Rodomiro Ortiz
Lepidium campestre (L.) or field cress is a multifaceted oilseed plant, which has not been domesticated yet. Moreover, the molecular and genetic mechanisms underlying the domestication traits of field cress remain largely elusive. The overarching goal is to identify quantitative trait loci (QTL) that are fundamental for domestication of field cress. Mapping and dissecting quantitative trait variation may provide important insights into genomic trajectories underlying field cress domestication. We used 7624 single nucleotide polymorphism (SNP)...

Data from: Resource dispersion and relatedness interact to explain space use in a solitary predator

Malin Aronsson, Mikael Åkesson, Matthew Low, Jens Persson & Henrik Andrén
Resource dispersion or kin selection are commonly used to explain animal spatial and social organization. Despite this, studies examining how these factors interact in wild populations of solitary animals are rare. We used 16 years of individual-level spatial and genetic data to disentangle how resources and relatedness influence spatial organization of a solitary predator, the Eurasian lynx (Lynx lynx). As expected, space-use overlap between neighbouring individuals increased when food resources were heterogeneous and unpredictably distributed...

Data from: Ecosystem service multifunctionality of low-productivity forests and implications for conservation and management

Mari Jönsson & Tord Snäll
Low-productivity forests are often the last remaining pristine forests in managed forest landscapes and typically overrepresented among protected forests. However, the provisioning of individual and multiple ecosystem services (ES-multifunctionality) by these forests remains poorly assessed, making it difficult to evaluate their importance in forest conservation and management. Using nationwide data on ecosystem services (ES) from forest plots, we test whether levels of ES-multifunctionality and individual ES differ between low-productivity forested mires and rocky outcrops in...

Examining the link between relaxed predation and bird colouration on islands

Louis Bliard, Matthieu Paquet, Aloïs Robert, Paul Dufour, Julien Renoult, Arnaud Gregoire, Pierre-Andre Crochet, Rita Covas & Claire Doutrelant
Insular ecosystems share analogous ecological conditions, leading to patterns of convergent evolution that are collectively termed the “island syndrome”. In birds, part of this syndrome is a tendency for a duller plumage, possibly as a result of relaxed sexual selection and the reduced need for species recognition. Despite this global pattern, some insular species display a more colourful plumage than their mainland relatives, but why this occurs has remained unexplained. Here, we examine the hypothesis...

Genotype data from: Restoration of transborder connectivity for Fennoscandian brown bears (Ursus arctos)

Alexander Kopatz, Kleven Oddmund, Kojola Ilpo, Aspi Jouni, Anita J. Norman, Göran Spong, Niclas Gyllenstrand, Love Dalén, Ida Fløystad, Snorre B. Hagen, Jonas Kindberg & Øystein Flagstad
Knowledge about the connectivity among natural populations is essential to identify management units for effective conservation actions. Conservation-minded management has led to the recovery of large carnivore populations in northern Europe, possibly restoring connectivity between the two separated, but expanding brown bear (Ursus arctos) populations on the Scandinavian peninsula to the west and Karelia, a part of the large Eurasian population, to the east. The degree of connectivity between these populations has been poorly understood,...

Population structure of five native sheep breeds of Sweden estimated with high density SNP genotypes

Christina Marie Rochus, Elisabeth Jonas & Anna M. Johansson
Background Native Swedish sheep breeds are part of the North European short-tailed sheep group; characterized in part by their genetic uniqueness. Our objective was to study the population structure of native Swedish sheep. Five breeds were genotyped using the 600 K SNP array. Dalapäls and Klövsjö sheep are from the middle of Sweden; Gotland and Gute sheep from Gotland, an island in the Baltic Sea; and Fjällnäs sheep from northern Sweden. We studied population structure...

Water stress and insect herbivory interactively reduce crop yield while the insect pollination benefit is conserved

Chloé Raderschall, Giulia Vico, Ola Lundin, Astrid Taylor & Riccardo Bommarco
Climate change is predicted to hamper crop production due to precipitation deficits and warmer temperatures inducing both water stress and increasing herbivory due to more abundant insect pests. Consequently, crop yields will be impacted simultaneously by abiotic and biotic stressors. Extensive yield losses due to such climate change stressors might, however, be mitigated by ecosystem services such as insect pollination. We examined the single and combined effects of water stress, insect herbivory and insect pollination...

Data from: Ecological speciation in European whitefish is driven by a large‐gaped predator

Gunnar Öhlund, Mats Bodin, Karin Nilsson, Sven-Ola Öhlund, Kenyon Mobley, Alan Hudson, Mikael Peedu, Åke Brännström, Pia Bartels, Kim Præbel, Catherine Hein, Petter Johansson & Göran Englund
Lake‐dwelling fish that form species pairs/flocks characterized by body size divergence are important model systems for speciation research. Although several sources of divergent selection have been identified in these systems, their importance for driving the speciation process remains elusive. A major problem is that in retrospect, we cannot distinguish selection pressures that initiated divergence from those acting later in the process. To address this issue, we studied the initial stages of speciation in European whitefish...

The effectiveness of flower strips and hedgerows on pest control, pollination services and crop yield: a quantitative synthesis

Matthias Albrecht, David Kleijn, Neal Williams, Matthias Tschumi, Brett Blaauw, Riccardo Bommarco, Alistair Campbell, Matteo Dainese, Frank Drummond, Martin Entling, Dominik Ganser, Arjen De Groot, David Goulson, Heather Grab, Hannah Hamilton, Felix Herzog, Rufus Isaacs, Katja Jacot, Philippe Jeanneret, Mattias Jonsson, Eva Knop, Claire Kremen, Doug Landis, Greg Loeb, Lorenzo Marini … & Louis Sutter
Floral plantings are promoted to foster ecological intensification of agriculture through provisioning of ecosystem services. However, a comprehensive assessment of the effectiveness of different floral plantings, their characteristics and consequences for crop yield is lacking. Here we quantified the impacts of flower strips and hedgerows on pest control (18 studies) and pollination services (17 studies) in adjacent crops in North America, Europe and New Zealand. Flower strips, but not hedgerows, enhanced pest control services in...

Crop diversity benefits carabid and pollinator communities in landscapes with semi-natural habitats

Guillermo Aguilera Núñez, Tomas Roslin, Kirsten Miller, Giovanni Tamburini, Klaus Birkhofer, Berta Caballero-Lopez, Sandra Lindström, Erik Öckinger, , Adrien Rusch, Henrik Smith & Riccardo Bommarco
1. In agricultural landscapes, arthropods provide essential ecosystem services such as biological pest control and pollination. Intensified crop management practices and homogenization of landscapes have led to declines among such organisms. Semi-natural habitats, associated with high numbers of these organisms, are increasingly lost from agricultural landscapes but diversification by increasing crop diversity has been proposed as a way to reverse observed arthropod declines and thus restore ecosystem services. However, whether or not an increase in...

Wild strawberry shows genetic variation in tolerance but not resistance to a generalist herbivore

Minggang Wang, Anne Muola, Peter Anderson & Johan Stenberg
Plants’ defenses against herbivores usually include both resistance and tolerance mechanisms. Their deployment has predominantly been studied in either single plant genotypes, or multiple genotypes exposed to single herbivores. In natural situations, however, most plants are attacked by multiple herbivores. Therefore, aims of this study were to assess and compare effects of single and multiple herbivores on plant resistance and tolerance traits, and the consequences for overall plant performance. For this, we exposed multiple genotypes...
