Data from: Trophic level, successional age and trait matching determine specialization of deadwood-based interaction networks of saproxylic beetles

Beate Wende, Martin M. Gossner, Ingo Grass, Tobias Arnstadt, Martin Hofrichter, Andreas Floren, Karl Eduard Linsenmair, Wolfgang W. Weisser & Ingolf Steffan-Dewenter
The specialization of ecological networks provides important insights into possible consequences of biodiversity loss for ecosystem functioning. However, mostly mutualistic and antagonistic interactions of living organisms have been studied, whereas detritivore networks and their successional changes are largely unexplored. We studied the interactions of saproxylic (deadwood-dependent) beetles with their dead host trees. In a large-scale experiment, 764 logs of 13 tree species were exposed to analyse network structure of three trophic groups of saproxylic beetles...

Data from: Multiple factors modulate tree growth complementarity in central European mixed forests

Marco Mina, Markus O. Huber, David I. Forrester, Esther Thürig & Brigitte Rohner
Mixed species forests can often be more productive and deliver higher levels of ecosystem services and functions than monocultures. However, complementarity effects for any given tree species are difficult to generalize because they can vary greatly along gradients of climatic conditions and resource availability. Identifying the conditions where species diversity can positively influence productivity is crucial. To date, few studies have examined how growth complementarity across species and mixture types is modulated by stand and...

Data from: Estimating age-dependent extinction: contrasting evidence from fossils and phylogenies

Oskar Hagen, Tobias Andermann, Tiago B. Quental, Alexandre Antonelli & Daniele Silvestro
The estimation of diversification rates is one of the most vividly debated topics in modern systematics, with considerable controversy surrounding the power of phylogenetic and fossil-based approaches in estimating extinction. Van Valen’s seminal work from 1973 proposed the “Law of constant extinction” which states that the probability of extinction of taxa is not dependent on their age. This assumption of age-independent extinction has prevailed for decades with its assessment based on survivorship curves, which, however,...

Data from: Integrating correlation between traits improves spatial predictions of plant functional composition

Rafael O. Wüest, Tamara Muenkenmuller, Sebastien Lavergne, Laura Pollock & Wilfried Thuiller
Functional trait composition is increasingly recognized as key to better understand and predict community responses to environmental gradients. Predictive approaches traditionally model the weighted mean trait values of communities (CWMs) as a function of environmental gradients. However, most approaches treat traits as independent regardless of known trade-offs between them, which could lead to spurious predictions. To address this issue, we suggest jointly modeling a suit of functional traits along environmental gradients while accounting for relationships...

Data from: Mammal-induced trophic cascades in invertebrate food webs are modulated by grazing intensity in subalpine grassland

Martijn L. Vandegehuchte, Martin Schütz, Frederic De Schaetzen & Anita C. Risch
1. Even though mammalian herbivores can exert strong indirect effects on other animals by altering the vegetation, the study of trophic cascades retains a focus on apex predators and their top-down forces. Bottom-up trophic interaction chains induced by mammalian herbivores, particularly in invertebrate food webs, remain largely unexplored. 2. We tested whether effects of mammalian herbivores on the vegetation ricochet back up several trophic levels of the invertebrate food web. We further tested two alternative...

Data from: Linking genetic and ecological differentiation in an ungulate with a circumpolar distribution

Glenn Yannic, Joaquín Ortego, Loïc Pellissier, Nicolas Lecomte, Louis Bernatchez & Steeve D. Côté
Genetic differentiation among populations may arise from the disruption of gene flow due to local adaptation to distinct environments and/or neutral accumulation of mutations and genetic drift resulted from geographical isolation. Quantifying the role of these processes in determining the genetic structure of natural populations remains challenging. Here, we analyze the relative contribution of isolation-by-resistance (IBR), isolation-by-environment (IBE), genetic drift and historical isolation in allopatry during Pleistocene glacial cycles on shaping patterns of genetic differentiation...

Data from: Land-use type and intensity differentially filter traits in above- and belowground arthropod communities

Klaus Birkhofer, Martin M. Gossner, Tim Diekötter, Claudia Drees, Olga Ferlian, Mark Maraun, Stefan Scheu, Wolfgang W. Weisser, Volkmar Wolters, Susanne Wurst, Andrey S. Zaitsev & Henrik G. Smith
1. Along with the global decline of species richness goes a loss of ecological traits. Associated biotic homogenization of animal communities and narrowing of trait diversity threaten ecosystem functioning and human well-being. High management intensity is regarded as an important ecological filter, eliminating species that lack suitable adaptations. Belowground arthropods are assumed to be less sensitive to such effects than aboveground arthropods. 2. Here, we compared the impact of management intensity between (grassland vs. forest)...

Data from: No carbon \"bet hedging\" in pine seedlings under prolonged summer drought and elevated CO2

Christoph Bachofen, Barbara Moser, Günter Hoch, Jaboury Ghazoul, Tom Wohlgemuth & Thomas Wohlgemuth
More frequent drought episodes are expected to cause higher mortality in isohydric tree species such as pines, because individuals close their stomata early during drought in order to maintain constant needle water potentials. It has been suggested that trees delay the ensuing carbon starvation by actively storing carbon at the expense of growth (“bet hedging”). Because such a strategy is only adaptive in drought-prone regions, we hypothesise that the degree of carbon “bet hedging” should...

Data from: HyRAD-X, a versatile method combining exome capture and RAD sequencing to extract genomic information from ancient DNA

Sarah Schmid, Rémi Genevest, Erika Gobet, Tomasz Suchan, Christoph Sperisen, Willy Tinner & Nadir Alvarez
Over the last decade, protocols aimed at reproducibly sequencing reduced-genome subsets in non-model organisms have been widely developed. Their use is however limited to DNA of relatively high molecular weight. During the last year, several methods exploiting hybridization capture using probes based on RAD-sequencing loci have circumvented this limitation and opened avenues to the study of samples characterized by degraded DNA, such as historical specimens. Here, we present a major update to those methods, namely...

Data from: The impact of even-aged and uneven-aged forest management on regional biodiversity of multiple taxa in European beech forests

Peter Schall, Martin M. Gossner, Steffi Heinrichs, Markus Fischer, Steffen Boch, Daniel Prati, Kirsten Jung, Vanessa Baumgartner, Stefan Blaser, Stefan Böhm, Francois Buscot, Rolf Daniel, Kezia Goldmann, Kirstin Kaiser, Tiemo Kahl, Markus Lange, Jörg Müller, Jörg Overmann, Swen C. Renner, Ernst-Detlef Schulze, Johannes Sikorski, Marco Tschapka, Manfred Türke, Wolfgang W. Weisser, Bernd Wemheuer … & Kristin Kaiser
For managed temperate forests, conservationists and policymakers favour fine-grained uneven-aged management over more traditional coarse-grained even-aged management, based on the assumption that within-stand habitat heterogeneity enhances biodiversity. There is, however, little empirical evidence to support this assumption. We investigated for the first time how differently grained forest management systems affect the biodiversity of multiple above- and below-ground taxa across spatial scales. We sampled 15 taxa of animals, plants, fungi and bacteria within the largest contiguous...

Data from: Fossils matter: improved estimates of divergence times in Pinus reveal older diversification

Bianca Saladin, Andrew B. Leslie, Rafael O. Wueest, Glenn Litsios, Elena Conti, Nicolas Salamin & Niklaus E. Zimmermann
Background: The taxonomy of pines (genus Pinus) is widely accepted and a robust gene tree based on entire plastome sequences exists. However, there is a large discrepancy in estimated divergence times of major pine clades among existing studies, mainly due to differences in fossil placement and dating methods used. We currently lack a dated molecular phylogeny that makes use of the rich pine fossil record, and this study is the first to estimate the divergence...

Data from: LiDAR-derived canopy structure supports the more-individuals hypothesis for arthropod diversity in temperate forests

Jörg Müller, Roland Brandl, Martin Brändle, Bernhard Förster, Bruno Cancian De Araujo, Martin M. Gossner, Alexander Ladas, Martin Wagner, Mark Maraun, Peter Schall, Stefan Schmidt, Marco Heurich, Simon Thorn & Sebastian Seibold
Despite considerable progress in the ability to measure the complex 3-D structure of forests with the improvement of remote-sensing techniques, our mechanistic understanding of how biodiversity is linked to canopy structure is still limited. Here we tested whether the increase in arthropod abundance and richness in beech forest canopies with increasing canopy complexity supports the more-individuals hypothesis or the habitat-heterogeneity hypothesis. We used fogging to collect arthropod samples from 80 standardized plots from canopies of...

Data from: Terrestrial reproduction as an adaptation to steep terrain in African toads

H. Christoph Liedtke, Hendrik Müller, Julian Hafner, Johannes Penner, David J. Gower, Tomáš Mazuch, Mark-Oliver Rödel & Simon P. Loader
How evolutionary novelties evolve is a major question in evolutionary biology. It is widely accepted that changes in environmental conditions shift the position of selective optima, and advancements in phylogenetic comparative approaches allow the rigorous testing of such correlated transitions. A longstanding question in vertebrate biology has been the evolution of terrestrial life histories in amphibians and here, by investigating African bufonids, we test whether terrestrial modes of reproduction have evolved as adaptations to particular...

Data from: Mammalian herbivores affect leafhoppers associated with specific plant functional types at different timescales

Martijn L. Vandegehuchte, Valeria Trivellone, Martin Schütz, Jennifer Firn, Frederic De Schaetzen & Anita C. Risch
1. Theory predicts that mammalian herbivores affect the quantity and quality of plants on which they preferentially feed in the short term. In the longer term, they can promote either preferred or less preferred plants, depending on whether preferred plants are adapted or sensitive to grazing. Less clear are the short- and long-term responses of herbivorous insects to mammalian herbivory, and how these responses depend on the specific plants or plant functional types on which...

Data from: Climatologies at high resolution for the earth's land surface areas

Dirk N. Karger, Olaf Conrad, Jürgen Böhner, Tobias Kawohl, Holger Kreft, Rodrigo W. Soria-Auza, Niklaus E. Zimmermann, H. Peter Linder & Michael Kessler
High-resolution information on climatic conditions is essential to many applications in environmental and ecological sciences. Here we present the CHELSA (Climatologies at high resolution for the earth’s land surface areas) data of downscaled model output temperature and precipitation estimates of the ERA-Interim climatic reanalysis to a high resolution of 30 arc sec. The temperature algorithm is based on statistical downscaling of atmospheric temperatures. The precipitation algorithm incorporates orographic predictors including wind fields, valley exposition, and...

Data from: Comparative assessment of SSR and SNP markers for inferring the population genetic structure of the common fungus Armillaria cepistipes

Tetyana Tsykun, Christian Rellstab, Cyril Dutech, György Sipos & Simone Prospero
During the last years, simple sequence repeats (SSRs, also known as microsatellites) and single-nucleotide polymorphisms (SNPs) have become the most popular molecular markers for describing neutral genetic variation in populations of a wide range of organisms. However, only a limited number of studies has focused on comparing the performance of these two types of markers for describing the underlying genetic structure of wild populations. Moreover, none of these studies targeted fungi, the group of organisms...

Data from: Biotic interactions and seed deposition rather than abiotic factors determine recruitment at elevational range limits of an alpine tree

Eike Lena Neuschulz, Dominik Merges, Kurt Bollmann, Felix Gugerli & Katrin Böhning-Gaese
1. Abiotic factors, biotic interactions and dispersal ability determine the spatial distribution of species. Theory predicts that abiotic constraints set range limits under harsh climatic conditions and biotic interactions set range limits under benign climatic conditions, whereas dispersal ability should limit both ends of the distribution. However, empirical studies exploring how these three components jointly affect species across environmental gradients are scarce. 2. Here we present a study that jointly examines these factors to investigate...

Data from: Axial xylem architecture of Larix decidua exposed to CO2 enrichment and soil warming at the treeline

Angela L. Prendin, Giai Petit, Patrick Fonti, Christian Rixen, Melissa Autumn Dawes & Georg Von Arx
1. Trees continuously adjust their axial xylem structure to meet changing needs imposed by ontogenetic and environmental changes. These axial structure-function responses need to be coordinated among competing biophysical constraints to avoid failure of the xylem system. Here, we investigated if ontogeny or experimental manipulation of CO2 and soil temperature influence these structure-function responses. 2. We performed detailed xylem cell anatomical quantification along the axis of 40-year-old Larix decidua trees planted at the Swiss treeline...

Data from: Interannual variations in needle and sapwood traits of Pinus edulis branches under an experimental drought

Marceau Guerin, Dario Martin-Benito, Georg Von Arx, Laia Andreu Hayles, Kevin L. Griffin, Rayann Hamdan, Nate G. McDowell, Robert Muscarella, Will Pockman, Pierre Gentine, William Pockman & Laia Andreu-Hayles
1) In the Southwest United States, recent large-scale die-offs of conifers raise the question of their resilience and mortality under droughts. To date, little is known about the interannual structural response to droughts. 2) We hypothesized that piñon pines (Pinus edulis) respond to drought by reducing the drop of leaf water potential in branches from year to year through needle morphological adjustments. We tested our hypothesis using a seven-year experiment in central New Mexico with...

Data from: Population genetic analysis of a parasitic mycovirus to infer the invasion history of its fungal host

Corine Schoebel, Leticia Botella, Vaidotas Lygis, Daniel Rigling & Corine N. Schoebel
Hymenoscyphus fraxineus mitovirus 1 (HfMV1) occurs in the fungus Hymenoscyphus fraxineus, an introduced plant pathogen responsible for the devastating ash dieback epidemic in Europe. Here, we explored the prevalence and genetic structure of HfMV1 in order to elucidate the invasion history of both the virus and the fungal host. A total of 1298 H. fraxineus isolates (181 from Japan and 1117 from Europe) were screened for the presence of this RNA virus and 301 virus-positive...

Data from: Habitat connectivity and local conditions shape taxonomic and functional diversity of arthropods on green roofs

Sonja Braaker, Martin Karl Obrist, Jaboury Ghazoul & Marco Moretti
Summary 1. Increasing development of urban environments creates high pressure on green spaces with potential negative impacts on biodiversity and ecosystem services. There is growing evidence that green roofs – rooftops covered with vegetation – can contribute mitigate the loss of urban green spaces by providing new habitats for numerous arthropod species. 2. Whether green roofs can contribute to enhance taxonomic and functional diversity and increase connectivity across urbanized areas remains, however, largely unknown. Furthermore,...

Data from: Belowground complementarity effects in a grassland biodiversity experiment are related to deep-rooting species

Natalie J. Oram, Janneke M. Ravenek, Kathryn E. Barry, Alexandra Weigelt, Hongmei Chen, Arthur Gessler, Annette Gockele, Hans De Kroon, Jan Willem Van Der Paauw, Michael Scherer-Lorenzen, Annemiek Smit-Tiekstra, Jasper Van Ruijven & Liesje Mommer
1. Belowground resource partitioning is often proposed as the underlying mechanism for the positive relationship between plant species richness and productivity. For example, if species have different root distributions, a mixture of plant species may be able to use the available resources more completely than the individual species in a monoculture. However, there is little experimental evidence for differentiation in vertical root distributions among species and its contribution to biodiversity effects. 2. We determined species-specific...
