Data from: Differential responses of herbivores and herbivory to management in temperate European beech

Martin M. Gossner, Esther Pašalić, Markus Lange, Patricia Lange, Dominik Hessenmöller, Jörg Müller, Stephanie A. Socher, Markus Fischer, Ernst-Detlef Schulze, Wolfgang W. Weisser & Steffen Boch
Forest management not only affects biodiversity but also might alter ecosystem processes mediated by the organisms, i.e. herbivory the removal of plant biomass by plant-eating insects and other arthropod groups. Aiming at revealing general relationships between forest management and herbivory we investigated aboveground arthropod herbivory in 105 plots dominated by European beech in three different regions in Germany in the sun-exposed canopy of mature beech trees and on beech saplings in the understorey. We separately...

Data from: A single-nucleotide polymorphism-based approach for rapid and cost-effective genetic wolf monitoring in Europe based on noninvasively collected samples

Robert H. S. Kraus, Bridgett VonHoldt, Berardino Cocchiararo, Verena Harms, Helmut Bayerl, Ralph Kühn, Daniel W. Förster, Jörns Fickel, Christian Roos & Carsten Nowak
Noninvasive genetics based on microsatellite markers has become an indispensable tool for wildlife monitoring and conservation research over the past decades. However, microsatellites have several drawbacks, such as the lack of standardisation between laboratories and high error rates. Here, we propose an alternative single-nucleotide polymorphism (SNP)-based marker system for noninvasively collected samples, which promises to solve these problems. Using nanofluidic SNP genotyping technology (Fluidigm), we genotyped 158 wolf samples (tissue, scats, hairs, urine) for 192...

Data from: Experimental test of plant defense evolution in four species using long-term rabbit exclosures

Teresa J. Didiano, Nash E. Turley, Georg Everwand, Hanno Schaefer, Michael J. Crawley & Marc T. J. Johnson
Plant defense traits have evolved over macro- and microevolutionary timescales in response to herbivores. Although a number of studies have investigated the evolutionary impacts of herbivores over short timescales, few studies have experimentally examined what defense traits most commonly evolve and whether multiple coexisting species exhibit similar evolutionary responses to herbivores. We addressed these questions using a long-term experiment at Silwood Park, England, United Kingdom, where we excluded rabbits from 38 grassland plots for <1...

Data from: Sequence co-evolution gives 3D contacts and structures of protein complexes

Thomas A. Hopf, Charlotta P. I. Schärfe, João P. G. L. M. Rodrigues, Anna G. Green, Chris Sander, Alexandre M. J. J. Bonvin, Debora S. Marks & Oliver Kohlbacher
Protein-protein interactions are fundamental to many biological processes. Experimental screens have identified tens of thousands of interactions and structural biology has provided detailed functional insight for select 3D protein complexes. An alternative rich source of information about protein interactions is the evolutionary sequence record. Building on earlier work, we show that analysis of correlated evolutionary sequence changes across proteins identifies residues that are close in space with sufficient accuracy to determine the three-dimensional structure of...

Data from: Functional identity and diversity of animals predict ecosystem functioning better than species-based indices

Vesna Gagic, Ignasi Bartomeus, Astrid Taylor, Camilla Winqvist, Christina Fischer, Eleanor M. Slade, Ingolf Steffan-Dewenter, Mark Emmerson, Simon G. Potts, Teja Tscharntke, Wolfgang Weisser, Riccardo Bommarco & T. Jonsson
Drastic biodiversity declines have raised concerns about the deterioration of ecosystem functions and have motivated much recent research on the relationship between species diversity and ecosystem functioning. A functional trait framework has been proposed to improve the mechanistic understanding of this relationship, but this has rarely been tested for organisms other than plants. We analysed eight datasets, including five animal groups, to examine how well a trait-based approach, compared with a more traditional taxonomic approach,...

Data from: Electromyographic permutation entropy quantifies diaphragmatic denervation and reinnervation

Christopher Kramer, Denis Jordan, Alexander Kretschmer, Veronika Lehmeyer, Kristine Kellermann, Stefan J. Schaller, Manfred Blobner, Eberhard F. Kochs, Heidrun Fink & Stephan J. Schaller
Spontaneous reinnervation after diaphragmatic paralysis due to trauma, surgery, tumors and spinal cord injuries is frequently observed. A possible explanation could be collateral reinnervation, since the diaphragm is commonly double-innervated by the (accessory) phrenic nerve. Permutation entropy (PeEn), a complexity measure for time series, may reflect a functional state of neuromuscular transmission by quantifying the complexity of interactions across neural and muscular networks. In an established rat model, electromyographic signals of the diaphragm after phrenicotomy...

Data from: Resource-mediated indirect effects of grassland management on arthropod diversity

Nadja K. Simons, Martin M. Gossner, Thomas M. Lewinsohn, Steffen Boch, Markus Lange, Jörg Müller, Esther Pašalić, Stephanie A. Socher, Manfred Türke, Markus Fischer & Wolfgang W. Weisser
Intensive land use is a driving force for biodiversity decline in many ecosystems. In semi-natural grasslands, land-use activities such as mowing, grazing and fertilization affect the diversity of plants and arthropods, but the combined effects of different drivers and the chain of effects are largely unknown. In this study we used structural equation modelling to analyse how the arthropod communities in managed grasslands respond to land use and whether these responses are mediated through changes...

Data from: Population signatures of large-scale, long-term disjunction and small-scale, short-term habitat fragmentation in an Afromontane forest bird

Jan Christian Habel, Luc Lens, Martin Husemann, Ronald K. Mulwa, Luca Borghesio, Franz Gassert, Dennis Rödder & Werner Ulrich
The Eastern Afromontane cloud forests occur as geographically distinct mountain exclaves. The conditions of these forests range from large to small and from fairly intact to strongly degraded. For this study, we sampled individuals of the forest bird species, the Montane White-eye Zosterops poliogaster from 16 sites and four mountain archipelagos. We analysed 12 polymorphic microsatellites and three phenotypic traits, and calculated Species Distribution Models (SDMs) to project past distributions and predict potential future range...

Data from: Niche divergence promotes rapid diversification of East African sky island white-eyes (Aves: Zosteropidae)

Siobhan C. Cox, Robert P. Prys-Jones, Jan C. Habel, Bernard A. Amakobe & Julia J. Day
The Eastern Afromontane biodiversity hotspot composed of highly fragmented forested highlands (sky islands) harbours exceptional diversity and endemicity, particularly within birds. To explain their elevated diversity within this region, models founded on niche conservatism have been offered, although detailed phylogeographic studies are limited to a few avian lineages. Here we focus on the recent songbird genus Zosterops, represented by montane and lowland members, to test the roles of niche conservatism versus niche divergence in the...

Data from: Speed of adaptation and genomic footprints of host-parasite coevolution under arms race and trench warfare dynamics

Aurélien Tellier, Stefany Moreno-Gámez & Wolfgang Stephan
Coevolution between hosts and their parasites is expected to follow a range of possible dynamics, the two extreme cases being called trench warfare (or Red Queen) and arms races. Long-term stable polymorphism at the host and parasite coevolving loci is characteristic of trench warfare, and is expected to promote molecular signatures of balancing selection, while the recurrent allele fixation in arms races should generate selective sweeps. We compare these two scenarios using a finite size...
