Data from: Landscape heterogeneity filters functional traits of rice arthropods in tropical agroecosystems

Christophe Dominik, Ralf Seppelt, Finbarr G. Horgan, Josef Settele & Tomáš Václavík
Biological control services of agroecosystems depend on the functional diversity of species traits. However, the relationship between arthropod traits and landscape heterogeneity is still poorly understood, especially in tropical rice agroecosystems which harbour a high diversity of often specialized species. We investigated how landscape heterogeneity, measured by three metrics of landscape composition and configuration, influenced body size, functional group composition, dispersal ability and vertical distribution of rice-arthropods in the Philippines. We found that landscape composition...

Data from: Multi-trophic guilds respond differently to changing elevation in a subtropical forest

Julia Binkenstein, Alexandra-Maria Klein, Thorsten Assmann, Francois Buscot, Alexandra Erfmeier, Keping Ma, Katherina A. Pietsch, Karsten Schmidt, Thomas Scholten, Tesfaye Wubet, Helge Bruelheide, Andreas Schuldt & Michael Staab
Negative relationships between species richness and elevation are common and attributed to changes in single environmental properties associated to elevation, such as temperature and habitat area. However, research has lacked taxonomic breadth and comprehensive elevation studies that consider multiple groups from different trophic levels are rare. We thus analysed 24 groups of plants, arthropods, and microorganisms grouped into six trophic guilds (predators, detritivores, herbivores, plants, bacteria and fungi) along a relatively short elevational gradient (~600...

Data from: A model-derived short-term estimation method of effective size for small populations with overlapping generations

Annegret Grimm, Bernd Gruber, Marion Hoehn, Katrin Enders & Klaus Henle
If not actively managed, small and isolated populations lose their genetic variability and the inbreeding rate increases. Combined, these factors limit the ability of populations to adapt to environmental changes, increasing their risk of extinction. The effective population size (Ne) is proportional to the loss of genetic diversity and therefore of considerable conservation relevance. However, estimators of Ne that account for demographic parameters in species with overlapping generations require sampling of populations across generations, which...

Data from: Interspecific competition alters leaf stoichiometry in 20 grassland species

Jordan Guiz, Anne Ebeling, Nico Eisenhauer, Nina Hacker, Lionel Hertzog, Yvonne Oelmann, Christiane Roscher, Cameron Wagg & Helmut Hillebrand
The extensive use of traits in ecological studies over the last few decades to predict community functions has revealed that plant traits are plastic and respond to various environmental factors. These plant traits are assumed to predict how plants compete and capture resources. Variation in stoichiometric ratios both within and across species reflects resource capture dynamics under competition. However, the impact of local plant diversity on species-specific stoichiometry remains poorly studied. Here, we analyze how...

Data from: Predicting forest management effects on oak–rodent mutualisms

Teresa Morán-López, Thorsten Wiegand, Juan Manuel Morales, Fernando Valladares & Mario Díaz
Wood mice Apodemus sylvaticus are the main dispersers of acorns in highly managed Mediterranean holm-oak woodlands. Mice mobilize and cache acorns to store them for winter consumption. They carry acorns away from potential competitors, face predation risks during mobilization, and cache acorns in areas where pilfering risks are low. However, mice can act either as net predators or as moderately efficient dispersers, depending on the way landscape management affects intraspecific competition for acorns and shelter...

Data from: Life in leaf litter: novel insights into community dynamics of bacteria and fungi during litter decomposition

Witoon Purahong, Tesfaye Wubet, Guillaume Lentendu, Michael Schloter, Marek J. Pecyna, Danuta Kapturska, Martin Hofrichter, Dirk Krüger & François Buscot
Microorganisms play a crucial role in the biological decomposition of plant litter in terrestrial ecosystems. Due to the permanently changing litter quality during decomposition, studies of both fungi and bacteria at a fine taxonomic resolution are required during the whole process. Here we investigated microbial community succession in decomposing leaf litter of temperate beech forest using pyrotag sequencing of the bacterial 16S and the fungal internal transcribed spacer (ITS) rRNA genes. Our results reveal that...

Data from: Plant species richness negatively affects root decomposition in grasslands

Hongmei Chen, Liesje Mommer, Jasper Van Ruijven, Hans De Kroon, Christine Fischer, Arthur Gessler, Anke Hildebrandt, Michael Scherer-Lorenzen, Christian Wirth & Alexandra Weigelt
Plant diversity enhances many ecosystem functions, including root biomass production, which drives soil carbon input. Although root decomposition accounts for a large proportion of carbon input for soil, little is known about plant diversity effect on this process. Plant diversity may affect root decomposition in two non-exclusive ways: by providing roots of different substrate quality (e.g. root chemistry) and/or by altering the soil environment (e.g. microclimate). To disentangle these two pathways, we conducted three decomposition...

Data from: Patterns of size variation in bees at a continental scale: does Bergmann’s rule apply?

Maxence Gérard, Maryse Vanderplanck, Markus Franzen, Michael Kuhlmann, Simon G. Potts, Pierre Rasmont, Oliver Schweiger & Denis Michez
Body size latitudinal clines have been widley explained by the Bergmann’s rule in homeothermic vertebrates. However, there is no general consensus in poikilotherms organisms in particular in insects that represent the large majority of wildlife. Among them, bees are a highly diverse pollinators group with high economic and ecological value. Nevertheless, no comprehensive studies of species assemblages at a phylogenetically larger scale have been carried out even if they could identify the traits and the...

Trait data of European and Maghreb butterflies

Joseph Middleton Welling, Leonardo Dapporto Dapporto, Enrique García-Barros, Martin Wiemers, Piotr Nowicki, Elisa Plazio, Simona Bonelli, Michele Zaccagno, Martina Šašić, Jana Lipárová, Oliver Schweiger, Alexander Harpke, Martin Musche, Josef Settele, Reto Schmucki & Tim Shreeve
Trait-based analyses explaining the different responses of species and communities to environmental changes are increasing in frequency. European butterflies are an indicator group that responds rapidly to environmental changes with extensive citizen science contributions to documenting changes of abundance and distribution. Species traits have been used to explain long- and short-term responses to climate, land-use and vegetation changes. Studies are often characterised by limited traits sets being used, with risks that the relative roles of...

Detection dogs in nature conservation: a database on their worldwide deployment with a review on breeds used and their performance compared to other methods

Annegret Grimm-Seyfarth, Wiebke Harms & Anne Berger
Over the last century, dogs have been increasingly used to detect rare and elusive species or traces of them. The use of wildlife detection dogs (WDD) is particularly well established in North America, Europe and Oceania, and projects deploying them have increased worldwide. However, if they are to make a significant contribution to conservation and management, their strengths, abilities, and limitations should be fully identified. We reviewed the use of WDD with particular focus on...

Biodiversity facets, canopy structure and surface temperature of grassland communities

Claudia Regina Guimaraes-Steinicke, Alexandra Weigelt, Raphaël Prouxl, Thomas Lanners, Nico Eisenhauer, Joaquín Duque-Lazo, Björn Reu, Christiane Roscher, Cameron Wagg, Nina Buchmann & Christian Wirth
Canopy structure is an important driver of the energy budget of the grassland ecosystem and is, at the same time, altered by plant diversity. Diverse plant communities typically have taller and more densely packed canopies than less diverse communities. With this, they absorb more radiation, have a higher transpiring leaf surface, and are better coupled to the atmosphere which leads to cooler canopy surfaces. However, whether plant diversity generally translates into a cooling potential remains...

Data from: Intraspecific trait variation increases species diversity in a trait-based grassland model

Michael Crawford, Florian Jeltsch, Felix May, Volker Grimm & Ulrike E. Schlägel
Intraspecific trait variation (ITV) is thought to play a significant role in community assembly, but the magnitude and direction of its influence are not well understood. Although it may be critical to better explain population persistence, species interactions, and therefore biodiversity patterns, manipulating ITV in experiments is challenging. We therefore incorporated ITV into a trait- and individual-based model of grassland community assembly by adding variation to the plants’ functional traits, which then drive life-history trade-offs....

Data from: Trait variation in response to varying winter temperatures, diversity patterns and signatures of selection along the latitudinal distribution of the widespread grassland plant Arrhenatherum elatius

Stefan G. Michalski, Andrey V. Malyshev & Juergen Kreyling
Across Europe, genetic diversity can be expected to decline toward the North because of stochastic and selective effects which may imply diminished phenotypic variation and less potential for future genetic adaptations to environmental change. Understanding such latitudinal patterns can aid provenance selection for breeding or assisted migration approaches. In an experiment simulating different winter temperatures, we assessed quantitative trait variation, genetic diversity, and differentiation for natural populations of the grass Arrhenatherum elatius originating from a...

Plant cover and plant-pollinator interactions in Central European grasslands (Poland/Czech Republic)

Demetra Rakosy, Elena Motivans, Valentin Ştefan, Arkadiusz Nowak, Sebastian Świerszcz, Reinart Feldmann, Elisabeth Kühn, Costanza Geppert, Neeraja Venkataraman, Anna Sobieraj-Betlińska, Anita Grossmann, Wiktoria Rojek, Katarzyna Pochrząst, Magdalena Cielniak, Anika Kirstin Gathof, Kevin Baumann & Tiffany Marie Knight
Complex socio-economic, political and demographic factors have driven the increased conversion of Europe’s semi-natural grasslands to intensive pastures. This trend is particularly strong in some of the most biodiverse regions of the continent, such as Central and Eastern Europe. Intensive grazing is known to decrease species diversity and alter the composition of plant and insect communities. Comparatively little is known, however, about how intensive grazing influences plant functional traits related to pollination and the structure...

Abundances of xylobiont beetles in the Leipzig floodplain forest 2016

Nora Haack, Ingo Brunk, Martin Schlegel, Detlef Bernhard, Klaus Henle, Annegret Grimm-Seyfarth & Christian Wirth
The dataset includes abundance data from xylobiont beetles, captured in the Leipzig floodplain forest between March and October 2016. We sampled three strata and three tree species. The strata were the understory with 2 traps, the lower canopy with 12 traps and the upper canopy with 12 traps. The 24 traps in the lower and upper canopy can further be assigned to the tree species Quercus robur, Tilia cordata and Fraxinus excelsior. Each tree was...

Data from: Genetic differentiation and regional adaptation among seed origins used for grassland restoration: lessons from a multispecies transplant experiment

Anna Bucharova, Stefan Michalski, Julia-Maria Hermann, Karola Heveling, Norbert Hölzel, Johannes Kollmann, Walter Durka & Oliver Bossdorf
One of the key questions in ecosystem restoration is the choice of seed material for restoring plant communities. More and more scientists and practitioners are currently advocating the use of regional seed sources, based on the argument that plants are often adapted to local or regional environmental conditions, and thus, regional seed sources should provide the best restoration success. However, there is still substantial debate about this approach, partly because of a lack of solid...

Data from: Invasion success in polyploids: the role of inbreeding in the contrasting colonization abilities of diploid versus tetraploid populations of Centaurea stoebe s.l

Christoph Rosche, Isabell Hensen, Patrik Mráz, Walter Durka, Matthias Hartmann & Susanne Lachmuth
As a consequence of founder effects, inbreeding can hamper colonization success: First, in species with self-incompatibility controlled by an S-locus, inbreeding may decrease cross-compatibility, mainly due to the sharing of identical S-alleles between closely related mating partners. Secondly, inbreeding can reduce fitness of inbred relative to outbred offspring (i.e. inbreeding depression). Polyploids often show reduced inbreeding depression compared to diploids, which may contribute to the overrepresentation of polyploids among invasive species. This is the first...

Data from: Light and nutrient dependent responses in secondary metabolites of Plantago lanceolata offspring are due to phenotypic plasticity in experimental grasslands

Annegret Miehe-Steier, Christiane Roscher, Michael Reichelt, Jonathan Gershenzon & Sybille B. Unsicker
A few studies in the past have shown that plant diversity in terms of species richness and functional composition can modify plant defense chemistry. However, it is not yet clear to what extent genetic differentiation of plant chemotypes or phenotypic plasticity in response to diversity-induced variation in growth conditions or a combination of both is responsible for this pattern. We collected seed families of ribwort plantain (Plantago lanceolata) from six-year old experimental grasslands of varying...

Data from: Neighbourhood effects on plant reproduction: an experimental-analytical framework and its application to the invasive Senecio inaequidens

Susanne Lachmuth, Colette Henrichmann, Juliane Horn, Joern Pagel & Frank M. Schurr
1. Density-dependence is of fundamental importance for population and range dynamics. Density-dependent reproduction of plants arises from competitive and facilitative plant-plant interactions that can be pollination-independent or pollination-mediated. In small and sparse populations, conspecific density-dependence often turns from negative to positive and causes Allee effects. Reproduction may also increase with heterospecific density (community-level Allee effect), but the underlying mechanisms are poorly understood and the consequences for community dynamics can be complex. Allee effects have crucial...

Data from: Too hot to die? The effects of vegetation shading on past, present, and future activity budgets of two diurnal skinks from arid Australia

Annegret Grimm-Seyfarth, Jean-Baptiste Mihoub & Klaus Henle
Behavioral thermoregulation is an important mechanism allowing ectotherms to respond to thermal variations. Its efficiency might become imperative for securing activity budgets under future climate change. For diurnal lizards, thermal microhabitat variability appears to be of high importance, especially in hot deserts where vegetation is highly scattered and sensitive to climatic fluctuations. We investigated the effects of a shading gradient from vegetation on body temperatures and activity timing for two diurnal, terrestrial desert lizards, Ctenotus...

Data from: Landscape composition, configuration, and trophic interactions shape arthropod communities in rice agroecosystems

Christophe Dominik, Ralf Seppelt, Finbarr G. Horgan, Josef Settele & Tomáš Václavík
1. Increasing landscape heterogeneity of agroecosystems can enhance natural enemy populations and promote biological control. However, little is known about the multi-scale effects of landscape heterogeneity on arthropod communities in rice agroecosystems, especially in combination with trophic interactions. 2. We examined for the first time how landscape heterogeneity, measured by four independent metrics of landscape composition and configuration at three spatial scales, affected species abundance and species richness of rice arthropods within four functional groups...

Data from: Sexual dimorphism modifies habitat‐associated divergence: evidence from beach and creek breeding sockeye salmon

Krista B. Oke, Elena Motivans, Thomas P. Quinn & Andrew P. Hendry
Studies of parallel or convergent evolution (the repeated, independent evolution of similar traits in similar habitats) rarely explicitly quantify the extent of parallelism (i.e., variation in the direction and/or magnitude of divergence) between the sexes; instead they often investigate both sexes together or exclude one sex. However, differences in male and female patterns of divergence could contribute to overall variation in the extent of parallelism among ecotype pairs, especially in sexually dimorphic traits. Failing to...

Data from: In situ analysis of a silver nanoparticle-precipitating Shewanella biofilm by surface enhanced confocal Raman microscopy

Gal Schkolnik, Matthias Schmidt, Marco G. Mazza, Falk Harnisch & Niculina Musat
Shewanella oneidensis MR-1 is an electroactive bacterium, capable of reducing extracellular insoluble electron acceptors, making it important for both nutrient cycling in nature and microbial electrochemical technologies, such as microbial fuel cells and microbial electrosynthesis. When allowed to anaerobically colonize an Ag/AgCl solid interface, S. oneidensis has precipitated silver nanoparticles (AgNp), thus providing the means for a surface enhanced confocal Raman microscopy (SECRaM) investigation of its biofilm. The result is the in-situ chemical mapping of...
