Data from: Bioclimatic variables derived from remote sensing: assessment and application for species distribution modeling

Eric Waltari, Ronny Schroeder, Kyle McDonald, Robert P. Anderson & Ana Carnaval
Remote sensing techniques offer an opportunity to improve biodiversity modeling and prediction worldwide. Yet, to date, the weather-station based WorldClim dataset has been the primary source of temperature and precipitation information used in correlative species distribution models. WorldClim consists of grids interpolated from in situ station data recorded primarily from 1960 to 1990. Those datasets suffer from uneven geographic coverage, with many areas of Earth poorly represented. Here, we compare two remote sensing data sources...

Data from: Genomic and phenotypic differentiation of Arabidopsis thaliana along altitudinal gradients in the North Italian Alps

Torsten Günther, Christian Lampei, Ivan Barilar & Karl J. Schmid
Altitudinal gradients in mountain regions are short-range clines of different environmental parameters such as temperature or radiation. We investigated genomic and phenotypic signatures of adaptation to such gradients in five Arabidopsis thaliana populations from the North Italian Alps that originated from 580 to 2350 m altitude by resequencing pools of 19–29 individuals from each population. The sample includes two pairs of low- and high-altitude populations from two different valleys. High-altitude populations showed a lower nucleotide...

Data from: Human–wildlife conflict, benefit sharing and the survival of lions in pastoralist community-based conservancies

Sara Blackburn, J. Grant C. Hopcraft, Joseph O. Ogutu, Jason Matthiopoulos & Laurence Frank
Like many wildlife populations across Africa, recent analyses indicate that African lions are declining rapidly outside of small fenced areas. Community conservancies – privately protected areas that engage community members in conservation – may potentially maintain wildlife populations in unfenced pastoralist regions, but their effectiveness in conserving large carnivores has been largely unknown until now. We identify drivers of lion survival in community conservancies within the Masai Mara ecosystem, Kenya, applying mark–recapture analyses to continuous...

Data from: Shifts in plant functional community composition under hydrological stress strongly decelerate litter decomposition

Julia Walter, Carsten Buchmann & Frank Schurr
Litter decomposition is a key process of nutrient and carbon cycling in terrestrial ecosystems. The decomposition process will likely be altered under ongoing climate change, both through direct effects on decomposer activity, and through indirect effects caused by changes in litter quality. We studied how hydrological change indirectly affects decomposition via plant functional community restructuring caused by changes in plant species´ relative abundances (community weighted mean traits (CWM) and functional diversity). We further assessed how...

Inter- and intraspecific selection in alien plants: how population growth, functional traits and climate responses change with residence time

Marco Brendel, Frank Schurr & Christine Sheppard
Aim: When alien species are introduced to new ranges, climate or trait mismatches may initially constrain their population growth. However, inter- and intraspecific selection in the new environment should cause population growth rates to increase with residence time. Using a species-for-time approach, we test whether with increasing residence time (a) negative effects of climatic mismatches between the species’ new and native range on population growth weaken, and (b) functional traits converge towards values that maximize...

Genome-wide association study in quinoa reveals selection pattern typical for crops with a short breeding history

Dilan Sarange Rajapaksha Patiranage, Elodie Rey, Nazgol Emrani, Gordon Wellman, Karl Schmid, Sandra Schmöckel, Mark Tester & Christian Jung
Quinoa germplasm preserves useful and substantial genetic variation, yet it remains untapped due to a lack of implementation of modern breeding tools. We have integrated field and sequence data to characterize a large diversity panel of quinoa. Whole-genome sequencing of 310 accessions revealed 2.9 million polymorphic high confidence SNP loci. Highland and Lowland quinoa were clustered into two main groups, with FST divergence of 0.36 and fast LD decay of 6.5 and 49.8 Kb, respectively....

Range-wide population viability analyses reveal high sensitivity to wildflower harvesting in extreme environments

Martina Treurnicht, Frank Schurr, Jasper Slingsby, Karen Esler & Joern Pagel
The ecological effects of harvesting from wild populations are often uncertain, especially since the sensitivity of populations to harvesting can vary across species’ geographical ranges. In the Cape Floristic Region (CFR, South Africa) biodiversity hotspot, wildflower harvesting is widespread and economically important, providing an income to many rural communities. However, with very few species studied to date, and without considering range-wide sensitivity to harvesting, there is limited information available to ensure the sustainability of wildflower...

This study analyzed the determinants of the job performance of field advisors who were working in a remote forest area. A stakeholder analysis was conducted to identify advisory organizations working in the Madhupur Sal forest, Tangail, Bangladesh. Data from 87 field advisors were collected in face-to-face interviews. The binary logistic regression was performed to identify the factors affecting the performance of the field advisors. Various factors drove the performance of field staff at organizational and...

Floral visitation to alien plants is non-linearly related to their phylogenetic and floral similarity to native plants

Mialy Razanajatovo, Mialy Razanajatovo, Felana Rakoto Joseph, Princy Rajaonarivelo Andrianina & Mark Van Kleunen
Biological invasions are key to understanding ecological processes that determine the formation of novel interactions. Alien species can negatively impact floral visitation to native species, but native species may also facilitate early establishment of closely related alien species by providing a preadapted pollinator community. We tested whether floral visitation to alien species depended on phylogenetic relatedness and floral similarity to native species. In a field experiment, we simulated the early stages of an invasion by...

Site impacts nutrient translocation efficiency in intra- and interspecies miscanthus hybrids on marginal lands

Elena Magenau, John Clifton-Brown, Danny Awty-Carroll, Chris Ashman, Andrea Ferrarini, Mislav Kontek, Enrico Martani, Kevin Roderick, Stefano Amaducci, Chris Davey, Vanja Jurišić, Jason Kam, Luisa Trindade, Iris Lewandowski & Andreas Kiesel
Miscanthus, a C4 perennial rhizomatous grass, is capable of growing in varied climates and soil types in Europe, including on marginal lands. It can produce high yields with low nutrient inputs when harvested after complete senescence. Senescence induction and rate depend on complex genetic, environmental, and management interactions. To explore these interactions, we analysed four miscanthus hybrids (two novel seed-based hybrids, GRC 3 (M. sinensis × sinensis) and GRC 14 (M. sacchariflorus × sinensis); GRC...

Livestock management promotes bush encroachment in savanna systems by altering plant-herbivore feedback

Franziska Koch, Britta Tietjen, Katja Tielbörger & Korinna Allhoff
This repository contains all code to reproduce the analysis in Koch et al. 2022 "Livestock management promotes bush encroachment in savanna systems by altering plant-herbivore feedback". We use a set of coupled differential equations to describe competition between shrubs and grasses, as well as plant biomass consumption via grazing and browsing. Grazers were assumed to receive a certain level of care from farmers, so that grazer densities emerge dynamically from the combined effect of vegetation...

Profile of clinical characteristics and serologic markers of sporadic hepatitis E in a community cohort study

Zi-Min Tang, Gui-Ping Wen, Dong Ying, Si-Ling Wang, Chang Liu, Wei-Kun Tian, Ying-Bin Wang, Mu-Jin Fang, Yu-Lin Zhou, Yun-Sheng Ge, Ting Wu, Jun Zhang, Shou-Jie Huang, Zi-Zheng Zheng & Ning-Shao Xia
Hepatitis E virus (HEV) is a pathogen of global significance, but the value of HEV-related markers in the diagnosis of hepatitis E remains controversial. Previous studies on hepatitis E profiles have been mainly cross-sectional and conducted among inpatients in large hospitals, and hepatitis E cases have been primarily defined by limited partial markers. In this community-based study, 4,110 active hepatitis cases from a population of nearly 600,000 were followed over 48 months and serial serum...

Data from: The Arabidopsis kinome: phylogeny and evolutionary insights into functional diversification

Monika Zulawski, Gunnar Schulze, Rostyslav Braginets, Stefanie Hartmann & Waltraud X. Schulze
Background: Protein kinases constitute a particularly large protein family in Arabidopsis with important functions in cellular signal transduction networks. At the same time Arabidopsis is a model plant with high frequencies of gene duplications. Here, we have conducted a systematic analysis of the Arabidopsis kinase complement, the kinome, with particular focus on gene duplication events. We matched Arabidopsis proteins to a Hidden-Markov Model of eukaryotic kinases and computed a phylogeny of 942 Arabidopsis protein kinase...

Data from: Meta-analysis of Arabidopsis thaliana phospho-proteomics data reveals compartmentalization of phosphorylation motifs

Klaas J. Van Wijk, Giulia Friso, Dirk Walther & Waltraud X. Schulze
Protein (de)phosphorylation plays an important role in plants. To provide a robust foundation for subcellular phosphorylation signaling network analysis and kinase-substrate relationships, we performed a meta-analysis of 27 published and unpublished in-house mass spectrometry–based phospho-proteome data sets for Arabidopsis thaliana covering a range of processes, (non)photosynthetic tissue types, and cell cultures. This resulted in an assembly of 60,366 phospho-peptides matching to 8141 nonredundant proteins. Filtering the data for quality and consistency generated a set of...

Wenxin Liu, Manje Gowda, Hans Peter Maurer, Sandra Fischer, Axel Schechert, Jochen C. Reif & Tobias Würschum
Joint linkage association mapping (JLAM) combines the advantages of linkage mapping and association mapping, and is a powerful tool to dissect the genetic architecture of complex traits. The main goal of this study was to use a cross-validation strategy, resample model averaging and empirical data analyses to compare seven different biometrical models for JLAM with regard to the correction for population structure and the quantitative trait loci (QTL) detection power. Three linear models and four...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...

Data from: Transgenerational effects of extreme weather: perennial plant offspring show modified germination, growth and stoichiometry

Julia Walter, David E. V. Harter, Carl Beierkuhnlein & Anke Jentsch
1) Climate change is predicted to increase the frequency and magnitude of extreme climatic events. These changes will directly affect plant individuals and populations and thus modify plant community composition. Little is known, however, about transgenerational effects (i.e. the influence of the parental environment on offspring phenotype and performance beyond the effects of transmitted genes) of climate extremes and community composition. Perennial plants have been particularly neglected. This impedes projections on species adaptations and population...

The trisaccharide melezitose impacts honey bees and their intestinal microbiota

Victoria Seeburger, Paul D'Alvise, Basel Shaaban, Karsten Schweikert, Getrud Lohaus, Annette Schroeder & Martin Hasselmann
In general, honey bees (Apis mellifera L.) feed on honey produced from collected nectar. In the absence of nectar, during certain times of the year or in monocultural landscapes, honey bees forage on honeydew. Honeydew is excreted by different herbivores of the order Hemiptera that consume phloem sap of plant species. In comparison to nectar, honeydew is composed of a higher variety of sugars and additional sugars with higher molecular weight, like the trisaccharide melezitose...

Data from: Foundation species promote local adaptation and fine-scale distribution of herbaceous plants

Michael O'Brien, Elisa Carbonell, Gianalberto Losapio, Philipp Schlüter & Christian Schöb
1) Interactions among neighbors can alter demography and traits of commingled species via adaptation or plasticity in phenotypic expression and understanding these two mechanisms in diverse communities is important for determining the ecological and evolutionary consequences of plant–plant interactions. 2) We reciprocally transplanted perennial species (Arenaria armerina and Festuca indigesta) among patches of two foundation shrub species and open ground to assess whether origin microsite (defined as the spatially distinct abiotic and biotic conditions associated...
