Data from: Effect of epistasis and environment on flowering time of barley reveals novel flowering-delaying QTL allele

Nazanin Pesaran Afsharyan, Wiebke Sannemann, Jens Léon & Agim Ballvora
Flowering time is a complex trait and has key role in crop yield and adaptation to environmental stressors such as heat and drought. The aim of this study was to better understand interconnected dynamic of epistasis and environment and look for novel regulators. For this purpose we investigated 534 spring barley MAGIC DH lines for flowering time at various environments. Analysis of QTL, epistatic interaction, QTL × environment (Q×E) and epistasis × environment (E×E) interactions...

Data from: A critical analysis of the potential for EU Common Agricultural Policy measures to support wild pollinators on farmland

Lorna Cole, David Kleijn, Lynn Dicks, Jane Stout, Simon Potts, Matthias Albrecht, Mario Balzan, Ignasi Bartomeus, Penelope Bebeli, Danilo Bevk, Jacobus Biesmeijer, Róbert Chlebo, Anželika Dautartė, Nikolaos Emmanouil, Chris Hartfield, John Holland, Andrea Holzschuh, Nieke Knoben, Anikó Kovács-Hostyánszki, Yael Mandelik, Heleni Panou, Robert Paxton, Theodora Petanidou, Miguel Pinheiro De Carvalho, … & Jeroen Scheper
1. Agricultural intensification and associated loss of high-quality habitats are key drivers of insect pollinator declines. With the aim of decreasing the environmental impact of agriculture, the 2014 EU Common Agricultural Policy (CAP) defined a set of habitat and landscape features (Ecological Focus Areas: EFAs) farmers could select from as a requirement to receive basic farm payments. To inform the post-2020 CAP, we performed a European-scale evaluation to determine how different EFA options vary in...

Data from: Pollinator dependence but no pollen limitation for eight plants occurring north of the Arctic Circle

Viviane Koch, Leana Zoller, Joanne M. Bennett & Tiffany M. Knight
Intact interactions between plants and pollinators are essential for the reproduction of pollinator-dependent plant species. Global change factors, such as climate change, have the potential to disrupt these interactions and subsequently impair pollination service. This disruption can result in insufficient pollen receipt for plants and lower their reproduction success. High latitude sites experience particularly rapid climate change and plants at these locations are expected to be vulnerable to lower reproductive success due to pollen limitation....

The mark of captivity: plastic responses in the ankle bone of a wild ungulate (Sus scrofa)

Thomas CUCCHI, Hugo Harbers, Dimitri Neaux, Katia Ortiz, Flavie Laurens, Isabelle Baly, Cécile Callou, Renate Schafberg, Ashleigh Haruda, François Lecompte, Jacqueline Studer, Sabrina Renaud, Yann Locatelli, Jean-Denis Vigne & Anthony Herrel
Deciphering the plastic (non-heritable) changes induced by human control over wild animals in the archaeological record is challenging. We hypothesized that changes in locomotor behaviour in a wild ungulate due to mobility control could be quantified in the bone anatomy. To test this, we experimented the effect of mobility reduction on the skeleton of wild boar (Sus scrofa), using the calcaneus shape as a possible phenotypic marker. We first assessed differences in shape variation and...

Data from: Estimating parent-specific QTL effects through cumulating linked identity-by-state SNP effects in multiparental populations

Andreas Maurer, Wiebke Sannemann, Jens Léon & Klaus Pillen
The emergence of multiparental mapping populations enabled plant geneticists to gain deeper insights into the genetic architecture of major agronomic traits and to map quantitative trait loci (QTLs) controlling the expression of these traits. Although the investigated mapping populations are similar, one open question is whether genotype data should be modelled as identical by state (IBS) or identical by descent (IBD). Whereas IBS simply makes use of raw genotype scores to distinguish alleles, IBD data...

Data from: Fungal disease incidence along tree diversity gradients depends on latitude in European forests

Diem Nguyen, Bastien Castagneyrol, Helge Bruelheide, Filippo Bussotti, Virginie Guyot, Hervé Jactel, Bogdan Jaroszewicz, Fernando Valladares, Jan Stenlid & Johanna Boberg
European forests host a diversity of tree species that are increasingly threatened by fungal pathogens, which may have cascading consequences for forest ecosystems and their functioning. Previous experimental studies suggest that foliar and root pathogen abundance and disease severity decrease with increasing tree species diversity, but evidences from natural forests are rare. Here, we tested whether foliar fungal disease incidence was negatively affected by tree species diversity in different forest types across Europe. We measured...

Pacific Introduced Flora (PacIFLora)

Michael Wohlwend, Dylan Craven, Patrick Weigelt, Hanno Seebens, Marten Winter, Holger Kreft, Wayne Dawson, Franz Essl, Mark Van Kleunen, Jan Pergl, Petr Pyšek, James Space, Philip Thomas & Tiffany Knight
The Pacific region has the highest density of naturalized plant species worldwide, which makes it an important area for research on the ecology, evolution and biogeography of biological invasions. While different data sources on naturalized plant species exist for the Pacific, there is no taxonomically and spatially harmonized database available for different subsets of species and islands. A comprehensive, accessible database containing the distribution of naturalized vascular plant species in the Pacific will enable new...

Transcriptomic signatures of ageing vary in solitary and social forms of an orchid bee

Alice Séguret, Eckart Stolle, Fernando Fleites-Ayil, Javier Quezada-Euán, Klaus Hartfelder, Karen Meusemann, Mark Harrison, Antonella Soro & Robert Paxton
Eusocial insect queens are remarkable in their ability to maximise both fecundity and longevity, thus escaping the typical trade-off between these two traits. Several mechanisms have been proposed to underlie the remoulding of the trade-off, such as reshaping of the juvenile hormone pathway, or caste-specific susceptibility to oxidative stress. However, it remains a challenge to disentangle the molecular mechanisms underlying the remoulding of the trade-off in eusocial insects from caste-specific physiological attributes that have subsequently...

Table S5: Occupancy change observations in bog species in the Black Forest (Germany) across all sites from 1972-2019

Helge Bruelheide & Thomas Sperle
Aim: Bogs and transition mires in Central Europe have undergone tremendous changes in the last decades, declining in spatial extent and favorable conservation status. However, species extinctions have been documented only rarely because of a lack of reliable floristic data. Here, we assessed species losses of bog complexes and analyzed their potential drivers. Location: Black Forest, Germany. Methods: We made use of the unique situation that the majority of bogs in the Black Forest (124...

Data from: Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilization

Dorothee Hodapp, Elizabeth T. Borer, W. Stanley Harpole, Eric M. Lind, Eric W. Seabloom, Peter B. Adler, Juan Alberti, Carlos A. Arnillas, Jonathan D. Bakker, Lori Biederman, Marc Cadotte, Elsa E. Cleland, Scott Collins, Philip A. Fay, Jennifer Firn, Nicole Hagenah, Yann Hautier, Oscar Iribarne, Johannes M.H. Knops, Rebecca L. McCulley, Andrew MacDougall, Joslin L. Moore, John W. Morgan, Brent Mortensen, Kimberly J. La Pierre … & Johannes M. H. Knops
Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental change typically quantify biotic responses at single spatial (time series within a single plot) or temporal (spatial beta-diversity at single time points) scales, ignoring their potential interdependence. Here, we use data from a global network of grassland experiments to determine how turnover responses to two major...

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: A longitudinal genetic survey identifies temporal shifts in the population structure of Dutch house sparrows

Laurence Cousseau, Martin Husemann, Ruud Foppen, Carl Vangestel & Luc Lens
Dutch house sparrow (Passer domesticus) densities dropped by nearly 50% since the early 1980s, and similar collapses in population sizes have been reported across Europe. Whether, and to what extent, such relatively recent demographic changes are accompanied by concomitant shifts in the genetic population structure of this species needs further investigation. Therefore, we here explore temporal shifts in genetic diversity, genetic structure and effective sizes of seven Dutch house sparrow populations. To allow the most...

Data from: Multi-trophic guilds respond differently to changing elevation in a subtropical forest

Julia Binkenstein, Alexandra-Maria Klein, Thorsten Assmann, Francois Buscot, Alexandra Erfmeier, Keping Ma, Katherina A. Pietsch, Karsten Schmidt, Thomas Scholten, Tesfaye Wubet, Helge Bruelheide, Andreas Schuldt & Michael Staab
Negative relationships between species richness and elevation are common and attributed to changes in single environmental properties associated to elevation, such as temperature and habitat area. However, research has lacked taxonomic breadth and comprehensive elevation studies that consider multiple groups from different trophic levels are rare. We thus analysed 24 groups of plants, arthropods, and microorganisms grouped into six trophic guilds (predators, detritivores, herbivores, plants, bacteria and fungi) along a relatively short elevational gradient (~600...

Data from: Elevated virulence of an emerging viral genotype as a driver of honeybee loss

Dino P. McMahon, Myrsini E. Natsopoulou, Vincent Doublet, Matthias Fürst, Silvio Weging, Mark J. F. Brown, Andreas Gogol-Döring & Robert J. Paxton
Emerging infectious diseases (EIDs) have contributed significantly to the current biodiversity crisis, leading to widespread epidemics and population loss. Owing to genetic variation in pathogen virulence, a complete understanding of species decline requires the accurate identification and characterization of EIDs. We explore this issue in the Western honeybee, where increasing mortality of populations in the Northern Hemisphere has caused major concern. Specifically, we investigate the importance of genetic identity of the main suspect in mortality,...

Data from: Herbivory and eutrophication mediate grassland plant nutrient responses across a global climatic gradient

T. Michael Anderson, Daniel M. Griffith, James B. Grace, Eric M. Lind, Peter B. Adler, Lori A. Biederman, Dana M. Blumenthal, Pedro Daleo, Jennifer Firn, Nicole Hagenah, W. Stanley Harpole, Andrew S. MacDougall, Rebecca L. McCulley, Suzanne M. Prober, Anita C. Risch, Mahesh Sankaran, Martin Schütz, Eric W. Seabloom, Carly J. Stevens, Lauren L. Sullivan, Peter D. Wragg & Elizabeth T. Borer
Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant stoichiometry and compare the relative contribution of climatic vs. anthropogenic effects. We addressed this goal by measuring plant elemental (C, N, P and K) responses to eutrophication and vertebrate herbivore exclusion at eighteen sites on six continents. Across sites, climate and...

Data from: Adaptive and non-adaptive evolution of trait means and genetic trait correlations for herbivory resistance and performance in an invasive plant

Karin Schrieber, Sabrina Wolf, Catherina Wypior, Diana Höhlig, Isabell Hensen & Susanne Lachmuth
The EICA-hypothesis predicts that invading plants adapt to their novel environment by evolving increased performance and reduced resistance in response to the release from natural enemies, and assumes a resource allocation tradeoff among both trait groups as mechanistic basis of this evolutionary change. Using the plant Silene latifolia as a study system, we tested these predictions by investigating whether 1) invasive populations evolved lower resistance and higher performance, 2) this evolutionary change is indeed adaptive,...

Data from: Characterization of unexplored deadwood mycobiome in highly diverse subtropical forests using culture-independent molecular technique

Witoon Purahong, Katherina A. Pietsch, Guillaume Lentendu, Ricardo Schöps, Helge Bruelheide, Christian Wirth, François Buscot & Tesfaye Wubet
The deadwood mycobiome, also known as wood-inhabiting fungi (WIF), are among the key players in wood decomposition, having a large impact on nutrient cycling in forest soils. However, our knowledge of WIF richness and distribution patterns in different forest biomes is limited. Here, we used pyrotag sequencing of the fungal internal transcribed spacer (ITS2) region to characterize the deadwood mycobiome of two tree species with greatly different wood characteristics (Schima superba and Pinus massoniana) in...

Data from: Genome-wide single nucleotide polymorphism scan suggests adaptation to urbanization in an important pollinator, the red-tailed bumblebee (Bombus lapidarius L.)

Panagiotis Theodorou, Rita Radzevičiūtė, Belinda Kahnt, Antonella Soro, Ivo Grosse & Robert J. Paxton
Urbanization is considered a global threat to biodiversity; the growth of cities results in an increase in impervious surfaces, soil and air pollution, fragmentation of natural vegetation, invasion of non-native species along with numerous environmental changes, including the heat island phenomenon. The combination of these effects constitutes a challenge for both the survival and persistence of many native species, whilst also imposing altered selective regimes. Here, using 110,314 single nucleotide polymorphisms (SNPs) generated by restriction-site...

Data from: A pre-Miocene Irano-Turanian cradle: origin and diversification of the species-rich monocot genus Gagea (Liliaceae)

Angela Peterson, Dörte Harpke, Jens Peterson, Alexander Harpke & Lorenzo Peruzzi
The Irano‐Turanian (IT) floristic region is considered an important centre of origin for many taxa. However, there is a lack of studies dealing with typical IT genera that also occur in neighbouring areas. The species-rich monocot genus Gagea Salisb. shows a centre of diversity in IT region and a distribution in adjacent regions, therefore representing a good study object to investigate spatial and temporal relationships among IT region and its neighbouring areas (East-Asia, Euro-Siberia, Himalaya,...

Data from: Sampling effects drive the species-area relationship in lake zooplankton

Leana Gooriah & Jonathan Chase
The Island Species-Area relationship (ISAR) describes how the numbers of species increases with increasing size of an island (or island-like habitat, such as lakes), and is one of the oldest laws in ecology. Despite its conceptual importance, there remains a great deal of ambiguity regarding the ISAR and its underlying processes. We compiled data from sampled zooplankton assemblages from several hundred lakes in North America and Europe to examine the influence of the three main...

The dataset contains COI barcodes of Lepidoptera caterpillars collected from a subtropical forest in Jiangxi, China.

Data from: A brief history and popularity of methods and tools used to estimate micro-evolutionary forces

Jonathan Kidner, Panagiotis Theodorou, Martin Husemann, Jan Engler & Martin Taubert
Population genetics is a field of research that predates the current generations of sequencing technology. Those approaches, that were established before massively parallel sequencing methods, have been adapted to these new marker systems (in some cases involving the development of new methods) that allow genome-wide estimates of the four major micro-evolutionary forces – mutation, gene flow, genetic drift and selection. Nevertheless, classic population genetic markers are still commonly used and a plethora of analysis methods...

Dataset for: Interactive effects of tree species composition and water availability on growth and direct and indirect defences in Quercus ilex

Andrea Galmán, Carla Vázquez-González, Gregory Röder & Bastien Castagneyrol
Plant diversity has often been reported to decrease insect herbivory in plants. Of the numerous mechanisms that have been proposed to explain this phenomenon, how plant diversity influences plant defences via effects on growth has received little attention. In addition, plant diversity effects may be contingent on abiotic conditions (e.g., resource and water availability). Here, we used a long-term experiment to explore the interactive effects of tree species composition and water availability on growth, direct...

Temporal trends in the spatial bias of species occurrence records

Diana Bowler, Corey Callaghan, Netra Bhandari, Klaus Henle, Benjamin Barth, Christian Koppitz, Reinhard Klenke, Marten Winter, Florian Jansen, Helge Bruelheide & Aletta Bonn
Large-scale biodiversity databases have great potential for quantifying long-term trends of species, but they also bring many methodological challenges. Spatial bias of species occurrence records is well recognized. Yet, the dynamic nature of this spatial bias - how spatial bias has changed over time - has been largely overlooked. We examined the spatial sampling bias of species occurrence records within multiple biodiversity databases in Germany and tested whether spatial bias in relation to land cover...
