1. Competition can be fully hierarchical or intransitive, and this degree of hierarchy is driven by multiple factors, including environmental conditions, the functional traits of the species involved or the topology of competition networks. Studies simultaneously analyzing these drivers of competition hierarchy are rare. Additionally, organisms compete either directly or via interference competition for resources or space, within a local neighbourhood or across the habitat. Therefore, the drivers of competition could change accordingly and depend...

Data from: Variation in home-field advantage and ability in leaf litter decomposition across successional gradients

G.F. Ciska Veen, Ashley D. Keiser, Wim H. Van Der Putten, David A. Wardle & G. F. Ciska Veen
1. It is increasingly recognized that interactions between plants and soil (a)biotic conditions can influence local decomposition processes. For example, decomposer communities may become specialized in breaking down litter of plant species that they are associated with, resulting in accelerated decomposition, known as ‘home-field advantage’ (HFA). Also, soils can vary inherently in their capacity to degrade organic compounds, known as ‘ability’. However, we have a poor understanding how environmental conditions drive the occurrence of HFA...

Data from: Modelling the co-evolution of indirect genetic effects and inherited variability

Jovana Marjanovic, Han A. Mulder, Lars Rönnegård & Piter Bijma
When individuals interact, their phenotypes may be affected by genes in their social partners, a phenomenon known as Indirect Genetic Effects (IGEs). In aquaculture species and some plants, competition not only affects trait levels of individuals, but also inflates variation of trait values among individuals. Variability of trait values has been studied as a quantitative trait in itself, and is often referred to as inherited variability. Although the observed phenotypic relationship between competition and variability...

Data from: Spatial contraction of demersal fish populations in a large marine ecosystem

Alessandro Orio, Ulf Bergström, Ann-Britt Florin, Andreas Lehmann, Ivo Šics & Michele Casini
Aim: The interdependencies between trophic interactions, environmental factors and anthropogenic forcing determine how species distributions change over time. Large changes in species distributions have occurred as a result of climate change. The objective of this study was to analyse how the spatial distribution of cod and flounder have changed in the Baltic Sea during the past four decades characterized by large hydrological changes. Location: Baltic Sea Taxon: Cod (Gadus morhua) and flounder (Platichthys flesus) Methods:...

Data from: Crop pests and predators exhibit inconsistent responses to surrounding landscape composition

Daniel S. Karp, Rebecca Chaplin-Kramer, Timothy D. Meehan, Emily A. Martin, Fabrice DeClerck, Heather Grab, Claudio Gratton, Lauren Hunt, Ashley E. Larsen, Alejandra Martínez-Salinas, Megan E. O’Rourke, Adrien Rusch, Katja Poveda, Mattias Jonsson, Jay A. Rosenheim, Nancy A. Schellhorn, Teja Tscharntke, Stephen D. Wratten, Wei Zhang, Aaron L. Iverson, Lynn S. Adler, Matthias Albrecht, Audrey Alignier, Gina M. Angelella, Muhammad Zubair Anjum … & Yi Zou
The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Data from: Annual flower strips support pollinators and potentially enhance red clover seed yield

, Ola Lundin & Riccardo Bommarco
1. Ecological intensification provides opportunity to increase agricultural productivity while minimizing negative environmental impacts, by supporting ecosystem services such as crop pollination and biological pest control. For this we need to develop targeted management solutions that provide critical resources to service-providing organisms at the right time and place. 2. We tested whether annual strips of early flowering phacelia Phacelia tanacetifolia support pollinators and natural enemies of seed weevils Protapion spp., by attracting and offering nectar...

Data from: Identifying native plants for coordinated habitat management of arthropod pollinators, herbivores and natural enemies

Ola Lundin, Kimiora L. Ward & Neal M. Williams
1. Providing non-crop flowering resources in agricultural landscapes is widely promoted as a strategy to support arthropods that deliver pollination and pest control services. However, management options have largely been developed separately for pollinators and natural enemies, whereas possible effects on insect herbivores, such as crop pests, have often been overlooked. A first critical step for design and implementation of multifunctional plantings that promote beneficial arthropods while controlling insect pests is to identify suitable plant...

Data from: Capturing genetic variation in crop wild relatives: an evolutionary approach

Paul A. Egan, Anne Muola & Johan A. Stenberg
Crop wild relatives (CWRs) offer novel genetic resources for crop improvement. To assist in the urgent need to collect and conserve CWR germplasm, we advance here the concept of an ‘evolutionary’ approach. Central to this approach is the predictive use of spatial proxies of evolutionary processes (natural selection, gene flow, and genetic drift) to locate and capture genetic variation. As a means to help validate this concept, we screened wild-collected genotypes of woodland strawberry (Fragaria...

Data from: Experimental rewilding enhances grassland functional composition and pollinator habitat use

Pablo Garrido, Anders Mårell, Erik Öckinger, Anna Skarin, Anna Jansson & Carl-Gustaf Thulin
1. Semi-natural grasslands are rich in biodiversity and thus important habitats for conservation, yet subjected to rapid declines due to agricultural intensification or abandonment. Promoting a more diverse mammalian herbivore community, including large and megaherbivores, may result in positive cascade effects for biodiversity and ecosystem functioning. Therefore, reintroducing an ecologically functional substitute of an extinct large herbivore could mitigate current biodiversity declines and foster semi-natural grassland conservation. 2. To test this hypothesis, we set up...

Data from: Pest suppression in cultivar mixtures is influenced by neighbor-specific plant-plant communication

Iris Dahlin, Diana Rubene, Robert Glinwood & Velemir Ninkovic
Increased plant genotypic diversity in crop fields can promote ecosystem services including pest control, but understanding of mechanisms behind herbivore population responses to cultivar mixtures is limited. We studied aphid settling on barley plants exposed to volatiles from different cultivars, aphid population development in monocultures and two-cultivar mixtures, and differences in volatile composition between studied cultivars. Aphid responses to one cultivar in a mixture were neighbor-specific and this was more important for pest suppression than...

Data from: Plasticity in leaf litter traits partly mitigates the impact of thinning on forest floor carbon cycling

Ludovic Henneron, Matthieu Chauvat, Frédéric Archaux, Marthe Akpa-Vinceslas, Fabrice Bureau, Yann Dumas, Francois Ningre, Claudine Richter, Philippe Balandier & Michael Aubert
1. Reducing stand density by thinning intensification has been emphasized as an efficient strategy of forest adaptation to climate change as it improves stand resistance to drought. Yet, it is still unclear how it could affect litter C cycling processes. Recent evidence indicates that the plasticity of an oak tree species can lead to a decline in its leaf litter quality and decomposability following thinning. The consequences for litter decomposition and forest floor C storage...

Data from: Conservation value of low-productive forests measured as the amount and diversity of dead wood and saproxylic beetles

Aino Hämäläinen, Joachim Strengbom & Thomas Ranius
In many managed landscapes, low-productive land comprises most of the remaining relatively untouched areas, and is often over-represented within protected areas. The relationship between the productivity and conservational value of a site is poorly known; however, it has been hypothesized that biodiversity increases with productivity due to higher resource abundance or heterogeneity, and that the species communities of low-productive land are a nested sub-set of communities from more productive land. We tested these hypotheses for...

Data from: Transient synchrony among populations of five foliage-feeding Lepidoptera

Maartje J. Klapwijk, Jonathan A. Walter, Aniko Hirka, György Csóka, Christer Björkman & Andrew M. Liebhold
1. Studies of transient population dynamics have largely focused on temporal changes in dynamical behavior, such as the transition between periods of stability and instability. The present study explores a related dynamic pattern, namely transient synchrony during a 49-year period among populations of five sympatric species of forest insects that share host tree resources. The long time-series allows a more comprehensive exploration of transient synchrony patterns than most previous studies. Considerable variation existed in the...

Data from: Limited dietary overlap amongst resident Arctic herbivores in winter - complementary insights from complementary methods

Niels M. Schmidt, Jesper B. Mosbacher, Eero J. Vesterinen, Tomas Roslin & Anders Michelsen
Snow may prevent Arctic herbivores from accessing their forage in winter, forcing them to aggregate in the few patches with limited snow. In High Arctic Greenland, Arctic hare and rock ptarmigan often forage in muskox feeding craters. We therefore hypothesized that due to limited availability of forage, the dietary niches of these resident herbivores overlap considerably, and that the overlap increases as winter progresses. To test this, we analyzed fecal samples collected in early and...

Data from: Management trade-offs on ecosystem services in apple orchards across Europe: direct and indirect effects of organic production

Ulrika Samnegard, Georgina Alins, Virginie Boreux, Jordi Bosch, Daniel García, Anne-Kathrin Happe, Alexandra Klein, Marcos Miñarro, Karsten Mody, Mario Porcel, Anselm Rodrigo, Laura Roquer-Beni, Marco Tasin, Peter A. Hambäck & Alexandra-Maria Klein
1. Apple is considered the most important fruit crop in temperate areas and profitable production depends on multiple ecosystem services, including the reduction of pest damage and the provision of sufficient pollination levels. Management approaches present an inherent trade-off as each affects species differently. 2. We quantified the direct and indirect effects of management (organic versus integrated pest management (IPM)) on species richness, ecosystem services and fruit production in 85 apple orchards in three European...

Data from: Can opportunistically-collected Citizen Science data fill a data gap for habitat suitability models of less common species?

Ute Bradter, Louise Mair, Mari Jönsson, Jonas Knape, Alexander Singer & Tord Snäll
1. Opportunistically-collected species observations contributed by volunteer reporters are increasingly available for species and regions for which systematically collected data are not available. However, it is unclear if they are suitable to produce reliable habitat suitability models (HSMs), and hence if the species-habitat relationships found and habitat suitability maps produced can be used with confidence to advice conservation management and address basic and applied research questions. 2. We evaluated HSMs with opportunistically-collected observations against HSMs...

Data from: Responses of macroinvertebrate communities to small dam removals: implications for bioassessment and restoration

Peter Erich Carlson, Serena Donadi & Leonard Sandin
1.Small dam removals are increasing on a global scale; yet general predictions of organism response to dam removal are constrained by heterogeneity of study designs, implementation strategies, geographies, and characteristics of dams and their removals. 2.Macroinvertebrate data extracted from 29 studies including 34 small dam removals over a broad geographical range was re-analysed utilizing dam removal effect sizes (a quantified change from before to after removal). Effect sizes of 10 metrics of community structure were...

Data from: Strategies of Phytophtora infestans adaptation to local UV radiation conditions

E-Jiao Wu, Yan-Ping Wang, Linin Shen, Lurwanu Yahuza, Jichen Tian, Lina Yang, LIping Shang, Wen Zhu, Jiasui Zhan, Lin-Lin Shen, Ji-Chen Tian, Li-Na Yang & Li-Ping Shang
Expected global changes in environmental conditions underline the need for a better understanding of genetic variation in ecological traits and their strategies of adaptation to the stresses. In this study, evolutionary mechanisms and processes of UV adaptation in plant pathogens were investigated by combining statistical genetics, physiological assays and common garden experiment approaches in an assessment of the potato late blight pathogen, Phytophthora infestans, sampled from various geographic locations in China. We found spatial divergence...

Data from: The role of plant-soil feedbacks in stabilizing a reindeer-induced vegetation shift in subarctic tundra

Dagmar Egelkraut, Paul Kardol, Jonathan R. De Long & Johan Olofsson
1.Herbivory can drive vegetation into different states of productivity and community composition, and these changes may be stable over time due to historical contingency effects. Interactions with abiotic and biotic soil components can contribute to such long‐term legacies in plant communities through stabilizing positive feedbacks. 2.We studied the role of plant‐soil feedbacks in maintaining vegetation changes caused by historical (~1350‐1900 AD) reindeer herding in northern Sweden. These historical milking grounds (HMGs) consist of meadow plant...

Data from: Plant odour and sex pheromone are integral elements of specific mate recognition in an insect herbivore

Felipe Borrero-Echeverry, Marie Bengtsson, Kiyoshi Nakamuta & Peter Witzgall
Specific mate recognition relies on the chemical senses in most animals, and especially in nocturnal insects. Two signal types mediate premating olfactory communication in terrestrial habitats: sex pheromones, which blend into an atmosphere of plant odorants. We show that host plant volatiles affect the perception of sex pheromone in males of the African cotton leafworm Spodoptera littoralis and that pheromone and plant volatiles are not perceived as independent messages. In clean air, S. littoralis males...

Data from: Effect of insect herbivory on plant community dynamics under contrasting water availability levels

Giovanni Tamburini, Elena Dani, Riccardo Bommarco & Lorenzo Marini
1. Diversity of plant communities is impacted by multiple global change drivers but also by altered biotic interactions with antagonist and mutualist organisms that can potentially affect species coexistence. 2. With a two-year outdoor mesocosm experiment in realistic mesic grassland communities, we explored the role of insect herbivory in impacting plant community dynamics under contrasting levels of water availability simulating altered rainfall regimes. We selected a grasshopper species (Calliptamus italicus) feeding predominantly on forbs while...

Data from: Does wolf presence reduce moose browsing intensity in young forest plantations?

Suzanne T.S. Van Beeck Calkoen, Dries P.J. Kuijper, Hakan Sand, Navinder J. Singh, Sip E. Van Wieren, Joris P.G.M. Cromsigt, Joris P. G. M. Cromsigt, Suzanne T. S. Van Beeck Calkoen & Dries P. J. Kuijper
Large carnivores can be a key factor in shaping their ungulate prey’s behavior, which may affect lower trophic levels. While most studies on trade-offs between food acquisition and risk avoidance by ungulate prey species have been conducted in areas with limited human impact, carnivores are now increasingly returning to highly anthropogenic landscapes. Many of these landscapes are dominated by forestry, and ungulate-forestry conflicts are an increasing issue. The aim of this study was to test...

Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements

Marlee A. Tucker, Katrin Böhning-Gaese, William F. Fagan, John M. Fryxell, Bram Van Moorter, Susan C. Alberts, Abdullahi H. Ali, Andrew M. Allen, Nina Attias, Tal Avgar, Hattie Bartlam-Brooks, Buuveibaatar Bayarbaatar, Jerrold L. Belant, Alessandra Bertassoni, Dean Beyer, Laura Bidner, Floris M. Van Beest, Stephen Blake, Niels Blaum, Chloe Bracis, Danielle Brown, P. J. Nico De Bruyn, Francesca Cagnacci, Justin M. Calabrese, Constança Camilo-Alves … & Thomas Mueller
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral...

Data from: Between-year changes in community composition shape species' roles in an Arctic plant-pollinator network

Alyssa R. Cirtwill, Tomas Roslin, Claus Rasmussen, Jens Mogens Olesen & Daniel B. Stouffer
Inter-annual turnover in community composition can affect the richness and functioning of ecological communities. If incoming and outgoing species do not interact with the same partners, ecological functions such as pollination may be disrupted. Here, we explore the extent to which turnover affects species' roles --as defined based on their participation in different motifs positions-- in a series of temporally replicated plant-pollinator networks from high-Arctic Zackenberg, Greenland. We observed substantial turnover in the plant and...

Data from: Soil microclimate changes affect soil fungal communities in a Mediterranean pine forest

Carles Castaño, Björn D. Lindahl, Josu G. Alday, Andreas Hagenbo, Juan Martínez De Aragón, Javier Parladé, Joan Pera & José Antonio Bonet
• Soil microclimate is a potentially important regulator of the composition of plant-associated fungal communities in climates with significant drought periods. Here, we investigated spatio-temporal dynamics of soil fungal communities in a Mediterranean Pinus pinaster forest in relation to soil moisture and temperature. • Fungal communities in 336 soil samples collected monthly during a year from 28 long-term experimental plots were assessed by PacBio sequencing of ITS2 amplicons. Total fungal biomass was estimated by analysing...
