Data from: Temperature effects on prey and basal resources exceed that of predators in an experimental community

Madhav P. Thakur, John N. Griffin, Tom Künne, Susanne Dunker, Andrea Fanesi & Nico Eisenhauer
Climate warming alters the structure of ecological communities by modifying species interactions at different trophic levels. Yet, the consequences of warming-led modifications in biotic interactions at higher trophic levels on lower trophic groups are lesser known. Here, we test the effects of multiple predator species on prey population size and traits, and subsequent effects on basal resources along an experimental temperature gradient (12-15C, 17-20C, and 22-25C). We experimentally assembled food web modules with two congeneric...

Data from: Convergent evolution of the ladder-like ventral nerve cord in Annelida

Conrad Helm, Patrick Beckers, Thomas Bartolomaeus, Stephan H. Drukewitz, Ioannis Kourtesis, Anne Weigert, Günter Purschke, Katrine Worsaae, Torsten H. Struck & Christoph Bleidorn
Background: A median, segmented, annelid nerve cord has repeatedly been compared to the arthropod and vertebrate nerve cords and became the most used textbook representation of the annelid nervous system. Recent phylogenomic analyses, however, challenge the hypothesis that a subepidermal rope-ladder-like ventral nerve cord (VNC) composed of a paired serial chain of ganglia and somata-free connectives represents either a plesiomorphic or a typical condition in annelids. Results: Using a comparative approach by combining phylogenomic analyses...

Data from: Incomplete datasets obscure associations between traits affecting dispersal ability and geographic range size of reef fishes in the Tropical Eastern Pacific

Adriana Alzate, Fons Van Der Plas, Fernando A. Zapata, Dries Bonte & Rampal S. Etienne
Dispersal is thought to be an important process determining range size, especially for species in highly spatially structured habitats, such as tropical reef fishes. Despite intensive research efforts, there is conflicting evidence about the role of dispersal on determining range size. We hypothesize that traits related to dispersal drive range sizes, but that complete and comprehensive datasets are essential for detecting relationships between species’ dispersal ability and range size. We investigate the roles of six...

Data from: Applying generalised allometric regressions to predict live body mass of tropical and temperate arthropods

Esra H. Sohlström, Lucas Marian, Andrew D. Barnes, Noor F. Haneda, Stefan Scheu, Björn C. Rall, Ulrich Brose & Malte Jochum
1. The ecological implications of body size extend from the biology of individual organisms to ecosystem–level processes. Measuring body mass for high numbers of invertebrates can be logistically challenging, making length-mass regressions useful for predicting body mass with minimal effort. However, standardised sets of scaling relationships covering a large range in body length, taxonomic groups, and multiple geographical regions are scarce. 2. We collected 6212 arthropods from 19 higher-level taxa in both temperate and tropical...

Data from: Growth responses to soil water potential indirectly shape local species distributions of tropical forest seedlings

Stefan J. Kupers, Bettina M.J. Engelbrecht, Andrés Hernández, S. Joe Wright, Christian Wirth, Nadja Rüger, Bettina M. J. Engelbrecht & S. Joseph Wright
1. Local tree species distributions in tropical forests correlate strongly with soil water availability. However, it is unclear how species distributions are shaped by demographic responses to soil water availability. Specifically, it remains unknown how growth affects species distributions along water availability gradients relative to mortality. 2. We quantified spatial variation in dry season soil water potential (SWP) in the moist tropical forest on Barro Colorado Island, Panama, and used a hierarchical Bayesian approach to...

Data from: Trait means, trait plasticity and trait differences to other species jointly explain species performances in grasslands of varying diversity

Christiane Roscher, Marlén Gubsch, Annett Lipowsky, Jens Schumacher, Alexandra Weigelt, Nina Buchmann, Ernst-Detlef Schulze & Bernhard Schmid
Functional traits may help to explain the great variety of species performances in plant communities, but it is not clear whether the magnitude of trait values of a focal species or trait differences to co-occurring species are key for trait-based predictions. In addition, trait expression within species is often plastic, but this variation has been widely neglected in trait-based analyses. We studied functional traits and plant biomass of 59 species in 66 experimental grassland mixtures...

Data from: Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs

Jennifer Firn, James M. McGree, Eric Harvey, Habacuc Flores-Moreno, Martin Schütz, Yvonne M. Buckley, Elizabeth T. Borer, Eric W. Seabloom, Kimberly J. La Pierre, Andrew M. MacDougall, Suzanne M. Prober, Carly J. Stevens, Lauren L. Sullivan, Erica Porter, Emma Ladouceur, Charlotte Allen, Karine H. Moromizato, John W. Morgan, W. Stanley Harpole, Yann Hautier, Nico Eisenhauer, Justin P. Wright, Peter B. Adler, Carlos Alberto Arnillas, Jonathan D. Bakker … & Anita C. Risch
Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental treatments across 27 globally distributed grassland sites across 4 continents. We find that specific leaf area (leaf area per unit mass)—a commonly measured morphological trait inferring shifts between plant growth strategies—did not respond to up to four years of soil nutrient additions. Leaf nitrogen, phosphorus...

Data from: Negative effects of litter richness on root decomposition in the presence of detritivores

Yinong Li, Xi Chen, Ciska GF Veen, Nico Eisenhauer, Yu Liang, Xiaomei Zhou, Naili Zhang, Keping Ma & G. F. Ciska Veen
1. Decomposition is a vital process underlying many ecosystem functions. Although a growing number of studies have tested how litter richness affects the decomposition of aboveground plant organs, knowledge remains limited about the decomposition of root mixtures. Here, we used a field experiment in a subtropical forest to investigate how species richness in root litter mixtures (air-dried fresh fine roots) affects the decomposition of root litter material. 2. Based on the concept of resource complementarity,...

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: Tree species richness increases ecosystem carbon storage in subtropical forests

Xiaojuan Liu, Stefan Trogisch, Jin-Sheng He, Pascal A. Niklaus, Helge Bruelheide, Zhiyao Tang, Alexandra Erfmeier, Michael Scherer-Lorenzen, Katherina A. Pietsch, Bo Yang, Peter Kühn, Thomas Scholten, Yuanyuan Huang, Chao Wang, Michael Staab, Katrin N. Leppert, Christian Wirth, Bernhard Schmid & Keping Ma
Forest ecosystems are an integral component of the global carbon cycle as they take up and release large amounts of C in short time (C flux) or accumulate it over longer time (C stock). However, there remains uncertainty about whether and in which direction C fluxes and in particular C stocks may differ between forests of high vs. low species richness. Based on a comprehensive dataset derived from field-based measurements, we tested the effect of...

Data from: Group and kin recognition via olfactory cues in chimpanzees (Pan troglodytes)

Stefanie Henkel & Joanna M. Setchell
Primates were traditionally thought to have a reduced sense of smell. Although there is now evidence that olfaction plays a greater role in primate social life than previously assumed, research on the sense of smell in non-human apes is scarce. Chimpanzees sniff the ground and vegetation on boundary patrols, but the function of this behaviour is unclear. Since chimpanzees are highly territorial and can kill individuals that do not belong to their own community, sniffing...

Data from: Cascading spatial and trophic impacts of oak decline on the soil food web

Jara Domínguez-Begines, Gerlinde B. De Deyn, Luis V. Garcia, Nico Eisenhauer & Lorena Gomez-Aparicio
1. Tree defoliation and mortality have considerably increased worldwide during the last decades due to global change drivers such as increasing drought or invasive pests and pathogens. However, the effects of this tree decline on soil food webs are poorly understood. 2. In this study we evaluated the impacts of Quercus suber decline on soil food webs of Mediterranean mixed forests invaded by the exotic oomycete pathogen Phytophthora cinnamomi, using soil nematodes as bioindicator taxa....

Data from: Gene flow in the European coal tit, Periparus ater (Aves: Passeriformes): low among Mediterranean populations but high in a continental contact zone

Christian Tritsch, Heiko Stuckas, Jochen Martens, Stefan Pentzold, Laura Kvist, Mario Lo Valvo, Gabriele Giacalone, Dieter Thomas Tietze, Alexander A. Nazarenko & Martin PÄckert
Extant phylogeographic patterns of Palearctic terrestrial vertebrates are generally believed to have originated from glacial range fragmentation. Post-Pleistocene range expansions have led to the formation of secondary contact zones among genetically distinct taxa. For coal tits (Periparus ater), such a contact zone has been localized in Germany. In this study, we quantified gene flow between Fennoscandian and southern European coal tits using a set of 13 microsatellite loci. STRUCTURE analysis revealed four genetic clusters two...

Data from: Below-ground resource partitioning alone cannot explain the biodiversity–ecosystem function relationship: a field test using multiple tracers

Annette Jesch, Kathryn E. Barry, Janneke M. Ravenek, Dörte Bachmann, Tanja Strecker, Alexandra Weigelt, Nina Buchmann, Hans De Kroon, Arthur Gessler, Liesje Mommer, Christiane Roscher & Michael Scherer-Lorenzen
1. Belowground resource partitioning is among the most prominent hypotheses for driving the positive biodiversity-ecosystem function relationship. However, experimental tests of this hypothesis in biodiversity experiments are scarce, and the available evidence is not consistent. 2. We tested the hypothesis that resource partitioning in space, in time, or in both space and time combined drives the positive effect of diversity on both plant productivity and community resource uptake. At the community level, we predicted that...

Data from: Biotic predictors complement models of bat and bird responses to climate and tree diversity in European forests

Luc Barbaro, Eric Allan, Evy Ampoorter, Bastien Castagneyrol, Yohan Charbonnier, Hans De Wandeler, Christian Kerbiriou, Harriet Milligan, Aude Vialatte, Monique Carnol, Marc Deconchat, Pallieter De Smedt, Herve Jactel, Julia Koricheva, Isabelle Le Viol, Bart Muys, Michael Scherer-Lorenzen, Kris Verheyen & Fons Van Der Plas
Bats and birds are key providers of ecosystem services in forests. How climate and habitat jointly shape their communities is well studied, but whether biotic predictors from other trophic levels may improve bird and bat diversity models is less known, especially across large bioclimatic gradients. Here, we achieved multi-taxa surveys in 209 mature forests replicated in six European countries from Spain to Finland, to investigate the importance of biotic predictors (i.e., the abundance or activity...
