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...

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...

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...

European soil seed bank communities across a climate and land-cover gradient

Jan Plue, Hans Van Calster, Inger Auestad, Sofia Basto, Reneé M. Bekker, Hans Henrik Bruun, Richard Chevalier, Guillaume Decocq, Ulf Grandin, Martin Hermy, Hans Jacquemyn, Anna Jakobsson, Rein Kalamees, Rob H. Marrs, Bryndis Marteinsdóttir, Per Milberg, Robin J. Pakeman, Gareth Phoenix, Ken Thompson, Vigdis Vandvik, Markus Wagner, Sara A.O. Cousins, Ove Eriksson, Jamshid Ghorbani, Małgorzata Jankowska-Błaszczuk … & Alistair G. Auffret
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...

Migration of tagged silver eels in the Atlantic 2006 - 2014

Known and estimated locations of silver European eels in the Atlantic from 2006 to 2014 derived from popup satellite tags and archival tags. Other data associated with the tagging experiments such as the length, weight, fat percentage, Pankhurst index and Fin index are also included. Locations were either known (from transmitted positions) or were estimated based on the temperature at depth data recorded by electronic tags (latitude) and the timing of steep dives at dawn...

Scripts and files for \"Small-scale population divergence is driven by local larval environment in a temperate amphibian\"

Patrik Rödin Mörch, Hugo Palejowski, Maria Cortazar-Chinarro, Simon Kärvemo, Alex Richter-Boix, Jacob Höglund & Anssi Laurila
Genomic variation within and among populations is shaped by the interplay between natural selection and the effects of genetic drift and gene flow. Adaptive divergence can be found in small scale natural systems even when population sizes are small and the potential for gene flow is high, suggesting that local environments exert selection pressures strong enough to counteract the opposing effects of drift and gene flow. Here, we investigated genomic differentiation in nine moor frog...

Data from: Impact of a recolonizing, cross-border carnivore population on ungulate harvest in Scandinavia

Camilla Wikenros, Håkan Sand, Johan Månsson, Erling Maartmann, Petter Wabakken & Barbara Zimmermann
Predation from large carnivores and human harvest are the two main mortality factors affecting the dynamics of many ungulate populations. We examined long-term moose (Alces alces) harvest data from two countries that share cross-border populations of wolves (Canis lupus) and their main prey moose. We tested how a spatial gradient of increasing wolf territory density affected moose harvest density and age and sex composition of the harvested animals (n = 549,310), along a latitudinal gradient...

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...

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...

Data from: Island properties dominate species traits in determining plant colonizations in an archipelago system

Mikael Von Numers, Sami Aikio, Satu Ramula & Anne Muola
The extrinsic determinants hypothesis emphasizes the essential role of environmental heterogeneity in species’ colonization. Consequently, high resident species diversity can increase community susceptibility to colonizations because good habitats may support more species that are functionally similar to colonizers. On the other hand, colonization success is also likely to depend on species traits. We tested the relative importance of environmental characteristics and species traits in determining colonization success using census data of 587 vascular plant species...

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 for: Microclimate structures communities, predation and herbivory in the High Arctic

Tuomas Kankaanpää, Nerea Abrego, Eero Vesterinen & Tomas Roslin
In a warming world, changes in climate may result in species-level responses as well as changes in community structure through knock-on effects on ecological interactions such as predation and herbivory. Yet, the links between these responses at different levels are still inadequately understood. Assessing how microclimatic conditions affect each of them at local scales provides information essential for understanding the consequences of macroclimatic changes projected in the future. Focusing on the rapidly changing High Arctic,...

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...

Stochastic processes and ecological connectivity drive stream invertebrate community responses to short-term drought

Romain Sarremejane, Amélie Truchy, Brendan McKie, Heikki Mykrä, Richard Johnson, Ari Huusko, Ryan Sponseller & Timo Muotka
1. Community responses to and recovery from disturbances depend on local (e.g. presence of refuges) and regional (connectivity to recolonization sources) factors. Droughts are becoming more frequent in boreal regions, and are likely to constitute a severe disturbance for boreal stream communities where organisms largely lack adaptations to such hydrological extremes. 2. We conducted an experiment in 24 seminatural stream flumes to assess the effects of local and regional factors on the responses of benthic...

Data from: Influence of canopy openness, ungulate exclosure, and low-intensity fire for improved oak regeneration in temperate Europe

Linda Petersson, Daniel Dey, Annika Felton, Emile Gardiner & Magnus Löf
Failed oak regeneration is widely reported in temperate forests and has been linked in part to changed disturbance regimes and land-use. We investigated if the North American fire-oak hypothesis could be applicable to temperate European oaks (Q. robur, Q. petraea) using a replicated field experiment with contrasting canopy openness, protection against ungulate browsing (fencing/no fencing), and low-intensity surface fire (burn/no burn). Survival, relative height growth (RGRH), browsing damage on naturally regenerated oaks (≤300 cm tall),...

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...

Data from: Roadside diversity in relation to age and surrounding source habitat: evidence for long time lags in valuable green infrastructure

Alistair Auffret & Evelina Lindgren
1. The severe and ongoing decline in semi-natural grassland habitat during the past two centuries means that it is important to consider how other, marginal grassland habitat elements can contribute to landscape-level biodiversity, and under what circumstances. 2. To examine how habitat age and the amount of core grassland habitat in the surrounding landscape affect diversity in green infrastructure, we carried out inventories of 36 rural road verges that were either historical (pre-1901) or modern...

Unravelling selection signatures in a single dog breed suggests recent selection for morphological and behavioural traits

Juliane Friedrich, Andrea Talenti, Per Arvelius, Erling Strandberg, Marie J Haskell & Pam Wiener
Strong selection has resulted in substantial morphological and behavioural diversity across modern dog breeds, which makes dogs interesting model animals to study the underlying genetic architecture of these traits. However, results from between-breed analyses may confound selection signatures for behaviour and morphological features that were co-selected during breed development. In this study, we assess population genetic differences in a unique resource of dogs of the same breed but with systematic behavioural selection in only one...

Trade-off between vegetation type, soil erosion control and surface water in global semi-arid regions: A meta-analysis

Gao-Lin Wu, Yi-Fan Liu, Zeng Cui, Yu Liu, Zhi-Hua Shi, Rui Yin & Paul Kardol
Soil erosion control and water resource protection can closely interact during restoration of terrestrial ecosystems. In semi‐arid ecosystems, an urgent issue is how vegetation restoration can achieve the goal of soil erosion mitigation and water conservation, which in turn, feeds back to ecosystem functioning. We reviewed 78 articles from 22 countries in semi‐arid areas to evaluate the effects of vegetation type (i.e. forest, grassland and scrubland) on runoff and sediment yields across different environmental conditions...

Threats from the air: damselfly predation on diverse prey taxa

Eero J. Vesterinen, Kari Kaunisto, , Mark Forbes, Andre Morrill, Anna Puisto, Ilari Sääksjärvi & Thomas Lilley
1. To understand the diversity and strength of predation in natural communities, researchers must quantify the total amount of prey species in the diet of predators. Metabarcoding approaches have allowed widespread characterization of predator diets with high taxonomic resolution. To determine the wider impacts of predators, researchers should combine DNA techniques with estimates of population size of predators using mark-release-recapture (MRR) methods, and with accurate metrics of food consumption by individuals. 2. Herein, we estimate...

Data from: Estimating density from presence/absence data in clustered populations

Magnus Ekström, Saskia Sandring, Anton Grafström, Per-Anders Esseen, Bengt Gunnar Jonsson & Göran Ståhl
1. Inventories of plant populations are fundamental in ecological research and monitoring, but such surveys are often prone to field assessment errors. Presence/absence (P/A) sampling may have advantages over plant cover assessments for reducing such errors. However, the linking between P/A data and plant density depends on model assumptions for plant spatial distributions. Previous studies have shown, for example, how that plant density can be estimated under Poisson model assumptions on the plant locations. In...

Data from: Crop production in the USA is frequently limited by a lack of pollinators

James Reilly, Derek Artz, David Biddinger, Kyle Bobiwash, Natalie Boyle, Claire Brittain, Julia Brokaw, Josh Campbell, Jaret Daniels, Elizabeth Elle, Jamie Ellis, Shelby Fleischer, Jason Gibbs, Robert Gillespie, Knute Gundersen, Larry Gut, George Hoffman, Neelendra Joshi, Ola Lundin, Keith Mason, Carley McGrady, Steve Peterson, Theresa Pitts-Singer, Sujaya Rao, Nikki Rothwell … & Rachael Winfree
Most of the world’s crops depend on pollinators, so declines in both managed and wild bees raise concerns about food security. However, the degree to which insect pollination is actually limiting current crop production is poorly understood, as is the role of wild species (as opposed to managed honey bees) in pollinating crops, particularly in intensive production areas. We established a nation-wide study to assess the extent of pollinator limitation in seven crops at 131...

Fifty years of European ungulate dietary studies: a synthesis

Robert Spitzer, Annika Felton, Marietjie Landman, Navinder Singh, Fredrik Widemo & Joris Cromsigt
Over recent decades, ungulate populations across Europe have undergone a rapid recovery. While this constitutes a conservation success, there is increasing concern about their impacts on shared resources with humans. Understanding ungulate food choices is crucial for predicting such impacts. Numerous studies have focused on single species or communities at narrow spatial scales. Here, we used 265 published diets from 87 European studies to investigate patterns of resource use by four common deer species (moose...

Disentangling ecological and taphonomic signals in ancient food webs

Jack Shaw, Emily Coco, Kate Wootton, Dries Daems, Andrew Gillreath-Brown, Anshuman Swain & Jennifer Dunne
Analyses of ancient food webs reveal important paleoecological processes and responses to a range of perturbations throughout Earth’s history, such as climate change. These responses can inform our forecasts of future biotic responses to similar perturbations. However, previous analyses of ancient food webs rarely accounted for key differences between modern and ancient community data, particularly selective loss of soft-bodied taxa during fossilization. To consider how fossilization impacts inferences of ancient community structure we (1) analyzed...
