1. Sedimentary pollen offers excellent opportunities to reconstruct vegetation changes over past millennia. Number of different pollen taxa or pollen richness is used to characterise past plant richness. To improve the interpretation of sedimentary pollen richness, it is essential to understand the relationship between pollen and plant richness in contemporary landscapes. This study presents a regional-scale comparison of pollen and plant richness from northern Europe and evaluates the importance of environmental variables on pollen and...

Data from: Expanding the toolbox of nutrient limitation studies: novel method of soil microbial in-growth bags to evaluate nutrient demands in tropical forests

Tessa Camenzind, Stefan Scheu & Matthias C. Rillig
1.Ecosystem processes and the organisms involved are generally limited by the availability of one or more element in soil, an important phenomenon to consider for our understanding of ecosystem functioning and future changes. Especially in tropical forests, typically growing on nutrient depleted soils, nitrogen (N), phosphorus (P) or other limitations are assumed. However, large‐scale nutrient manipulation experiments revealed complex site‐specific patterns and several authors raised the need for novel approaches to reveal deeper mechanistic insights...

Managing agricultural landscapes to support biodiversity and ecosystem services is a key aim of a sustainable agriculture. However, how the spatial arrangement of crop fields and other habitats in landscapes impacts arthropods and their functions is poorly known. Synthesising data from 49 studies (1515 landscapes) across Europe, we examined effects of landscape composition (% habitats) and configuration (edge density) on arthropods in fields and their margins, pest control, pollination and yields. Configuration effects interacted with...

Data from: Linking size spectrum, energy flux and trophic multifunctionality in soil food webs of tropical land-use systems

Anton M. Potapov, Bernhard Klarner, Dorothee Sandmann, Rahayu Widyastuti & Stefan Scheu
1. Many ecosystem functions depend on the structure of food webs, which heavily relies on the body size spectrum of the community. Despite that, little is known on how the size spectrum of soil animals responds to agricultural practices in tropical land-use systems and how these responses affect ecosystem functioning. 2. We studied land-use induced changes in belowground communities in tropical lowland ecosystems in Sumatra (Jambi province, Indonesia), a hotspot of tropical rainforest conversion to...

Candidate-gene association analysis for a continuous phenotype with a spike at zero using parent-offspring trios

Nadja Klein, Andrew Entwistle, Albert Rosenberger, Thomas Kneib & Heike Bickeböller
In this paper, we propose the class of generalized additive models for location, scale and shape in a test for the association of genetic markers with non-normally distributed phenotypes comprising a spike at zero. The resulting statistical test is a generalization of the quantitative transmission disequilibrium test with mating type indicator, which was originally designed for normally distributed quantitative traits and parent-offspring data. As a motivational example, we consider coronary artery calcification (CAC), which can...

Data from: The effect of drought and season on root life span in temperate arbuscular mycorrhizal and ectomycorrhizal tree species

Rebecca Liese, Christoph Leuschner & Ina Christin Meier
1. Fine roots play a key role in carbon (C) and nutrient cycling, since fine root lifespan drives soil organic C input and, thus, N availability. The two principal fungal symbioses found in temperate forest trees, ectomycorrhizae (ECM) and arbuscular mycorrhizae (AM), induce different root morphological changes upon infection, but the consequences for root lifespan are not clear. 2. We explored differences in fine root lifespan between four AM and four ECM tree species using...

Data from: Exposure and susceptibility drive reinfection with gastrointestinal parasites in a social primate

Nadine Müller-Klein, Michael Heistermann, Christina Strube, Mathias Franz, Oliver Schülke & Julia Ostner
1. Increased risk of infectious disease transmission has been proposed as one major cost of group living. While factors corresponding to transmission via exposure to infectious stages and susceptibility to infections upon contact are relatively well understood, both aspects are rarely investigated simultaneously. 2. Here, we assessed the influence of exposure and susceptibility measures on strongyle nematode reinfection after experimental deworming of Barbary macaques (Macaca sylvanus) (n=57). We investigated impacts of behaviour (social bonds, grooming...

Data from: No signal of deleterious mutation accumulation in conserved gene sequences of extant asexual hexapods

Alexander Brandt, Jens Bast, Stefan Scheu, Karen Meusemann, Alexander Donath, Kai Schütte, Ryuichiro Machida & Ken Kraaijeveld
Loss of sex and recombination is generally assumed to impede the effectiveness of purifying selection and to result in the accumulation of slightly deleterious mutations. Empirical evidence for this has come from several studies investigating mutational load in a small number of individual genes. However, recent whole transcriptome based studies have yielded inconsistent results, hence questioning the validity of the assumption of mutational meltdown in asexual populations. Here, we study the effectiveness of purifying selection...

Data from: Trophic consistency of supraspecific taxa in belowground invertebrate communities: comparison across lineages and taxonomic ranks

Anton M. Potapov, Stefan Scheu & Alexei V. Tiunov
1. Animals that have similar morphological traits are expected to share similar ecological niches. This statement applies to individual animals within a species and thus species often serve as the functional units in ecological studies. Species are further grouped into higher-ranked taxonomic units based on their morphological similarity and thus are also expected to be ecologically similar. On the other hand, theory predicts that strong competition between closely related species may result in differentiation of...

Data from: How a measure of tree structural complexity relates to architectural benefit-to-cost ratio, light availability and growth of trees

Dominik Seidel, Peter Annighofer, Melissa Stiers, Clara Delphine Zemp, Katharina Burkardt, Martin Ehbrecht, Katharina Willim, Holger Kreft, Dirk Hölscher & Christian Ammer
Aboveground tree architecture is neither fully deterministic nor random. It is likely the result of mechanisms that balance static requirements and light-capturing efficiency. Here we used terrestrial laser scanning data to investigate the relationship between tree architecture, here addressed using the box-dimension (Db), and the architectural benefit-to-cost ratio, the light availability and the growth of trees. We detected a clear relationship between Db and the benefit-to-cost ratio for the tested three temperate forest tree species...

Data from: Compound-specific isotope analysis of amino acids as new tool to uncover trophic chains in soil food webs

Melanie M. Pollierer, Thomas Larsen, Anton Potapov, Adrian Brückner, Michael Heethoff, Jens Dyckmans & Stefan Scheu
Food webs in soil differ fundamentally from those above ground; they are based on inputs from both living plants via root exudates, and from detritus, which is a complex mixture of fungi, bacteria and dead plant remains. Trophic relationships are difficult to disentangle due to cryptic lifestyle of soil animals and inevitable microbial contributions to their diet. Compound-specific isotope analysis of amino acids (AAs) is increasingly used to explore complex food webs. The combined use...

Data from: Old World and New World Phasmatodea: phylogenomics resolve the evolutionary history of stick and leaf insects

Sabrina Simon, Harald Letsch, Sarah Bank, Thomas R. Buckley, Alexander Donath, Shanlin Liu, Ryuichiro Machida, Karen Meusemann, Bernhard Misof, Lars Podsiadlowski, Xin Zhou, Benjamin Wipfler & Sven Bradler
Phasmatodea comprises over 3,000 extant species and stands out as one of the last remaining insect orders for which a robust, higher-level phylogenetic hypothesis is lacking. New research suggests that the extant diversity is the result of a surprisingly recent and rapid radiation that has been difficult to resolve with standard Sanger sequence data. In order to resolve the early branching events of stick and leaf insects, we analyzed transcriptomes from 61 species, including 38...

Epidermal Growth Factor signaling promotes sleep through a combined series and parallel neural circuit

Jan Konietzka, Maximilian Fritz, Silvan Spiri, Rebecca McWhirter, Andreas Leha, Sierra Palumbos, Wagner Steuer Costa, Alexandra Oranth, Alexander Gottschalk, , Alex Hajnal & Henrik Bringmann
Sleep requires sleep-active neurons that depolarize to inhibit wake circuits. Sleep-active neurons are under the control of homeostatic mechanisms that determine sleep need. However, little is known about the molecular and circuit mechanisms that translate sleep need into the depolarization of sleep-active neurons. During many stages and conditions in C. elegans, sleep requires a sleep-active neuron called RIS. Here, we defined the transcriptome of RIS to discover that genes of the Epidermal Growth Factor Receptor...

Data from: Global fern and lycophyte richness explained: how regional and local factors shape plot richness

Michael Kessler, Anna Weigand, Helge Bruelheide, Hanna Tuomisto, Holger Kreft & Patrick Weigelt
Aim To disentangle the influence of environmental factors at different spatial grains (regional and local) on fern and lycophyte species richness and ask how regional and plot-level richness are related to each other. Location Global. Time Period Present. Major Taxa studied Ferns and lycophytes. Methods We explored fern and lycophyte species richness at two spatial grains, regional (hexagonal grid cells of 7666 km2) and plot-level (300–500 m2), in relation to environmental data at regional and...

Data from: Invasive lumbricid earthworms in North America – different life-histories but common dispersal?

Andreas Klein, Nico Eisenhauer & Ina Schaefer
Aim Lumbricid earthworms are invasive across northern North America, causing notable changes in forest ecosystems. During their range expansion, they encountered harsher climatic conditions compared to their native ranges in short time (~400 years). This study investigated if (1) dispersal barriers, (2) climatic selection, or (3) anthropogenic activities, i.e. fishing bait disposal, structure the dispersal of free-living earthworm populations. Location North America, forest habitats along former Wisconsinan glaciation line Taxon Lumbricus terrestris, L. rubellus Methods...

Desert-like badlands and surrounding (semi-)dry grasslands of Central Germany promote small-scale phenotypic and genetic differentiation in Thymus praecox

Kevin Karbstein, Salvatore Tomasello & Kathleen Prinz
Environmental heterogeneity among sites can generate phenotypic and genetic variation facilitating differentiation and microevolution of plant populations. Badlands are desert-like, predominantly vegetation-poor habitats often embedded in (semi-)dry grasslands. The desert-like conditions of badlands demand extreme adaptation of plants, i.e., phenotypic modifications in short-term and/or natural adaptation in long-term. However, detailed knowledge is missing about both plant phenotypic and genetic differentiation in this unique and widely occurring habitat type. The present study focused on the largest...

Data from: Estimating interactions between individuals from concurrent animal movements

Ulrike E. Schlägel, Johannes Signer, Antje Herde, Sophie Eden, Florian Jeltsch, Jana Eccard & Melanie Dammhahn
1. Animal movements arise from complex interactions of individuals with their environment, including both conspecific and heterospecific individuals. Animals may be attracted to each other for mating, social foraging, or information gain, or may keep at a distance from others to avoid aggressive encounters related to, e.g., interference competition, territoriality, or predation. With modern tracking technology, more data sets are emerging that allow to investigate fine-scale interactions between free-ranging individuals from movement data, however, few...

Data from: Ecosystem services and disservices by birds, bats and monkeys change with macadamia landscape heterogeneity

Valerie M. G. Linden, Ingo Grass, Elsje Joubert, Teja Tscharntke, Sina M. Weier & Peter J. Taylor
1.The relative importance of ecosystem services and disservices can change with landscape structure in a poorly understood way. 2.We compare the impact of biocontrol, provided by bats and birds, with that of crop raiding by vervet monkeys on yield in South African macadamia orchards. Insectivorous bats and birds are known to feed on macadamia pest insect species, like the macadamia nut borer or the green vegetable bug. Vervet monkeys move into the orchards during the...

Data from: Differing climatic mechanisms control transient and accumulated vegetation novelty in Europe and eastern North America

Kevin Burke, John Williams, Simon Brewer, Walter Finsinger, Thomas Giesecke, David Lorenz & Alejandro Ordonez
Understanding the mechanisms that produce novel ecosystems is of joint interest to conservation biologists and paleoecologists. Here, we define and differentiate transient from accumulated novelty and evaluate four climatic mechanisms proposed to cause species to reshuffle into novel assemblages: high climatic novelty, high spatial rates of change (displacement), high variance among displacement rates for individual climate variables, and divergence among displacement vector bearings. We use climate simulations to quantify climate novelty, displacement, and divergence across...
