The study of mutualistic interaction networks has led to valuable insights into ecological and evolutionary processes. However, our understanding of network structure may depend upon the temporal scale at which we sample and analyze network data. To date, we lack a comprehensive assessment of the temporal scale-dependence of network structure across a wide range of temporal scales and geographic locations. If network structure is temporally scale-dependent, networks constructed over different temporal scales may provide very...

We report data from a fertilization experiment in three temperate beech forest with contrasting soil phosphorus concentrations. We used soil cores and the fractions of the organic layer and mineral topsoil separately of spring and fall 2018. We collected bulk soil and roots. We provide data on soil for pH, mineral elements, ammonium, nitrate,...

Data from: Nest attentiveness drives nest predation in arctic sandpipers

Nicolas Meyer, Loïc Bollache, François-Xavier Dechaume-Moncharmont, Jerôme Moreau, Eve Afonso, Anders Angerbjörn, Joël Bety, Dorothee Ehrich, Vladimir Gilg, Marie-Andrée Giroux, Jannik Hansen, Richard Lanctot, Johannes Lang, Nicolas Lecomte, Laura McKinnon, Jeroen Reneerkens, Sarah Saalfeld, Brigitte Sabard, Niels Schmidt, Benoît Sittler, Paul Smith, Aleksandr Sokolov, Vasiliy Sokolov, Natalya Sokolova, Rob Van Bemmelen … & Olivier Gilg
Most birds incubate their eggs to allow embryo development. This behaviour limits the ability of adults to perform other activities. Hence, incubating adults trade-off incubation and nest protection with foraging to meet their own needs. Parents can either cooperate to sustain this trade-off or incubate alone. The main cause of reproductive failure at this reproductive stage is predation and adults reduce this risk by keeping the nest location secret. Arctic sandpipers are interesting biological models...

The aim of the study was to determine the effect of belowground plant-derived carbohydrates on P uptake, P concentrations and enzymes activities related to P mobilization in roots, ectomycorrhizas and soil and on the abundances of P-related genes in soil bacteria. We report data from a girdling experiment in two temperate beech forest with contrasting soil phosphorus concentrations. We used soil cores and the fractions of the organic layer and mineral topsoil separately one and...

Forest habitat parameters influence abundance and diversity of cadaver-visiting dung beetles in Central Europe

Christian Von Hoermann, Sandra Weithmann, Markus Deißler, Manfred Ayasse & Sandra Steiger
Dung beetles (Scarabaeoidea) provide crucial ecosystem services and serve as model organisms for various behavioural, ecological and evolutionary studies. However, dung beetles have received little attention as consumers of large cadavers. In this study, we trapped copronecrophagous dung beetles on aboveground exposed piglet cadavers in 61 forest plots distributed over three geographically distinct regions in Germany, Central Europe. We examined the effects of land use intensity, forest stand, soil characteristics, vascular plant diversity and climatic...

Analysis of RNA-seq, DNA target enrichment, and Sanger nucleotide sequence data resolves deep splits in the phylogeny of cuckoo wasps (Hymenoptera: Chrysididae)

Thomas Pauli, Karen Meusemann, Sandra Kukowka, Manuela Sann, Alexander Donath, Christoph Mayer, Jan Philip Oeyen, Yolanda Ballesteros, Alexander Berg, Eric Van Den Berghe, Hermes Escalona, Adalgisa Guglielmino, Manfred Niehuis, Massimo Olmi, Lars Podsiadlowski, Carlo Polidori, Jeroen De Rond, Paolo Rosa, Thomas Schmitt, Franco Strumia, Mareike Wurdack, Shanlin Liu, Xin Zhou, Bernhard Misof, Ralph Peters … & Oliver Niehuis
The wasp family Chrysididae (cuckoo wasps, gold wasps) comprises exclusively parasitoid and kleptoparasitic species, many of which feature a stunning iridescent coloration and phenotypic adaptations to their parasitic life style. Previous attempts to infer phylogenetic relationships among the family’s major lineages (subfamilies, tribes, genera) based on Sanger sequence data were insufficient to statistically resolve the monophyly and the phylogenetic position of the subfamily Amiseginae and the phylogenetic relationships among the tribes Allocoeliini, Chrysidini, Elampini, and...

Data from: Tree litter functional diversity and nitrogen concentration enhance litter decomposition via changes in earthworm communities

Guillaume Patoine, Helge Bruelheide, Josephine Haase, Charles Nock, Niklas Ohlmann, Benjamin Schwarz, Michael Scherer-Lorenzen & Nico Eisenhauer
Biodiversity is a major driver of numerous ecosystem functions. However, consequences of changes in forest biodiversity remain difficult to predict because of limited knowledge about how tree diversity influences ecosystem functions. Litter decomposition is a key process affecting nutrient cycling, productivity and carbon storage, and can be influenced by plant biodiversity. Leaf litter species composition, environmental conditions, and the detritivore community are main components of the decomposition process, but their complex interactions are poorly understood....

Data from: Anonymous faecal sampling and NIRS studies of diet quality: problem or opportunity?

Luca Corlatti
Investigating the drivers of diet quality is a key issue in wildlife ecology and conservation. Faecal near infrared reflectance spectroscopy (f-NIRS) is widely used to study dietary quality since it allows for noninvasive, rapid and low-cost analysis of nutrients. Samples for f-NIRS can be collected and analyzed with or without knowledge of animal identities. While anonymous sampling allows to reduce the costs of individual identification, as it neither requires physical captures nor DNA genotyping, it...

Contrasting patterns of sexually selected traits in Mediterranean and continental populations of European mouflon

Kresimir Kavcic, Luca Corlatti, Toni Safner, Nikola Budak & Nikica Šprem
The expression of sexually selected traits in highly dimorphic ungulates may be influenced by environmental quality. Variations in habitat conditions can impose different constraints on the allocation of energy resources to male life-history traits, and possibly alter the female preferences for specific features. Here, we compared the horn growth patterns in male European mouflon Ovis aries musimon living in different habitats (Mediterranean vs. continental) but sharing a common genetic origin. We hypothesized that the expression...

Jonathan Henshaw
This dataset (Antechinus.csv) relates to the worked example in the appendix of the paper: Henshaw JM, Morrissey MB, Jones AG (2020). Quantifying the causal pathways contributing to natural selection. Evolution (doi:​10.1111/evo.14091) The worked example concerns a hypothetical study of female antechinus. These are small carnivorous marsupials that use torpor to reduce energy consumption from late summer to early winter. They reproduce once per year in late winter or early spring, following which most individuals die....

Data from: Four myriapod relatives – but who are sisters? No end to debates on relationships among the four major myriapod subgroups

Nikolaus U. Szucsich, Daniela Bartel, Alexander Blanke, Alexander Böhm, Alexander Donath, Makiko Fukui, Simon Grove, Shanlin Liu, Oliver Macek, Ryuichiro Machida, Bernhard Misof, Yasutaka Nakagaki, Lars Podsiadlowski, Kaoru Sekiya, Shigekazu Tomizuka, Björn M. Von Reumont, Robert M. Waterhouse, Manfred Walzl, Guanliang Meng, Xin Zhou, Günther Pass & Karen Meusemann
Background: Phylogenetic relationships among the myriapod subgroups Chilopoda, Diplopoda, Symphyla and Pauropoda are still not robustly resolved. The first phylogenomic study covering all subgroups resolved phylogenetic relationships congruently to morphological evidence but is in conflict with most previously published phylogenetic trees based on diverse molecular data. Outgroup choice and long-branch attraction effects were stated as possible explanations for these incongruencies. In this study, we addressed these issues by extending the myriapod and outgroup taxon sampling...

A novel method to measure hairiness in bees and other insect pollinators

Laura Roquer-Beni, Jordi Bosch, Anselm Rodrigo, Xavier Arnan, Alexandra-Maria Klein, Felix Fornoff & Virginie Boreux
1. Hairiness is a salient trait of insect pollinators that has been linked to thermoregulation, pollen uptake and transportation, and pollination success. Despite its potential importance in pollination ecology, hairiness is rarely included in pollinator trait analyses. This is likely due to the lack of standardized and efficient methods to measure hairiness. 2. We describe a novel methodology that uses a stereomicroscope equipped with a live measurement module software to quantitatively measure two components of...

Data from: The functional roles of species in metacommunities, as revealed by metanetwork analyses of bird-plant frugivory networks

Hai-Dong Li, Linfang Tang, Chenxi Jia, Marcel Holyoak, Jochen Fründ, Xiaoqun Huang & Zhihsu Xiao
Understanding how biodiversity and interaction networks change across environmental gradients is a major challenge in ecology. We integrated metacommunity and metanetwork perspectives to test species’ functional roles in bird-plant frugivory interactions in a fragmented forest landscape in Southwest China, with consequences for seed dispersal. Availability of fruit resources both on and under trees created vertical feeding stratification for frugivorous birds. Bird-plant interactions involving birds feeding only on the tree or both on and under the...

Data from: Presynaptic GABAB receptors functionally uncouple somatostatin interneurons from the active hippocampal network

Sam A. Booker, Harumi Harada, Claudio Elguate, Julia Bank, Bartos Marlene, Akos Kulik & Imre Vida
Information processing in cortical neuronal networks relies on properly balanced excitatory and inhibitory neurotransmission. A ubiquitous motif for maintaining this balance is the somatostatin interneuron (SOM-IN) feedback microcircuit. Here, we investigate the modulation of this microcircuit by presynaptic GABAB receptors (GABABRs) in the rat hippocampus. Whole-cell recordings from SOM-INs reveal that both excitatory and inhibitory synaptic inputs are strongly inhibited by GABABRs, while optogenetic activation of the interneurons shows that their inhibitory output is also...

Data from: An integrative phylogenomic approach to elucidate the evolutionary history and divergence times of Neuropterida (Insecta: Holometabola)

Alexandros Vasilikopoulos, Bernhard Misof, Karen Meusemann, Doria Lieberz, Tomáš Flouri, Rolf G. Beutel, Oliver Niehuis, Torsten Wappler, Jes Rust, Ralph S. Peters, Alexander Donath, Lars Podsiadlowski, Christoph Mayer, Daniela Bartel, Alexander Böhm, Shanlin Liu, Paschalia Kapli, Carola Greve, James E. Jepson, Xingyue Liu, Xin Zhou, Horst Aspöck & Ulrike Aspöck
Background The latest advancements in DNA sequencing technologies have facilitated the resolution of the phylogeny of insects, yet parts of the tree of Holometabola remain unresolved. The phylogeny of Neuropterida has been extensively studied, but no strong consensus exists concerning the phylogenetic relationships within the order Neuroptera, and the timeline of diversification of thelineages of Neuropterida. Here, we assembled a novel transcriptomic dataset to address previously unresolved issues in the phylogeny of Neuropterida and to...

Multiscale drivers of carabid beetle (Coleoptera: Carabidae) assemblages in small European woodlands

Ronan Marrec, Vincent Le Roux, Ludmilla Martin, Jonathan Lenoir, Jörg Brunet, Sara Cousins, Pallieter De Smedt, Marc Deconchat, Martin Diekmann, Steffen Ehrmann, Emilie Gallet-Moron, Brice Giffard, Jaan Liira, Jessica Lindgren, Alicia Valdés, Kris Verheyen, Monika Wulf & Guillaume Decocq
Aim The spatiotemporal connectivity of forest patches in lowland agricultural landscapes and their age matter to explain current biodiversity patterns across regional as well as biogeographical extents, to the point that it exceeds the contribution of macroclimate for plant diversity in the understory of temperate forests. Whether this holds true for other taxonomic groups remains largely unknown. Yet, it has important consequences for ecosystem functioning and the delivery of ecosystem services. Focusing on carabid beetle...

In the shadows of snow leopards and the Himalayas: density and habitat selection of blue sheep in Manang, Nepal

Marc Filla, Rinzin Phunjok Lama, Tashi Rapte Ghale, Johannes Signer, Tim Filla, Raja Ram Aryal, Marco Heurich, Matthias Waltert, Niko Balkenhol & Igor Khorozyan
There is a growing agreement that conservation needs to be proactive and pay increased attention to common species and to the threats they face. The blue sheep (Pseudois nayaur) plays a key ecological role in sensitive high-altitude ecosystems of Central Asia and is among the main prey species for the globally vulnerable snow leopard (Panthera uncia). As the blue sheep has been increasingly exposed to human pressures, it is vital to estimate its population dynamics,...
