Data from: RNA-Seq analysis identifies genes associated with differential reproductive success under drought-stress in accessions of wild barley Hordeum spontaneum

Sariel Hübner, Abraham B. Korol & Karl J. Schmid
Background: The evolutionary basis of reproductive success in different environments is of major interest in the study of plant adaptation. Since the reproductive stage is particularly sensitive to drought, genes affecting reproductive success during this stage are key players in the evolution of adaptive mechanisms. We used an ecological genomics approach to investigate the reproductive response of drought-tolerant and sensitive wild barley accessions originating from different habitats in the Levant. Results: We sequenced mRNA extracted...

Data from: Multiple simultaneous treatments change plant response from adaptive parental effects to within-generation plasticity, in Arabidopsis thaliana

Christian Lampei
In general, studies on plant phenotypic plasticity concentrate on plant responses to different levels of a single environmental factor. Under natural conditions, however, multiple environmental factors often vary simultaneously. I studied the consequences for lifetime fitness caused by single treatments or treatment combinations by investigating patterns of phenotypic plasticity within and between generations. The parental plants (3 genotypes of the annual plant Arabidopsis thaliana) received zero, one or two stress treatments at an early life-stage....

Data from: Phenotypic landscapes: phenological patterns in wild and cultivated barley

Sariel Hübner, Eyal Bdolach, Shachaf Ein-Gedy, Karl J. Schmid, Abraham Korol & Eyal Fridman
Phenotypic variation in natural populations is the outcome of the joint effects of environmentally induced adaptations and neutral processes on the genetic architecture of quantitative traits. In this study we examined the role of adaptation in shaping wild barley phenotypic variation along different environmental gradients. Detailed phenotyping of 164 wild barley (Hordeum spontaneum) accessions from Israel (of the Barley1K collection), and 18 cultivated barley (H. vulgare) varieties, was conducted in common garden field trials. Cluster...

Diversification in evolutionary arenas – assessment and synthesis

Nicolai M. Nürk, H. Peter Linder, Renske E. Onstein, Matthew J. Larcombe, Colin E. Hughes, Laura Piñeiro Fernández, Philipp M. Schlüter, Luis Valente, Carl Beierkuhnlein, Vanessa Cutts, Michael J. Donoghue, Erika J. Edwards, Richard Field, Suzette G.A. Flantua, Steven I. Higgins, Anke Jentsch, Sigrid Liede-Schumann & Michael D. Pirie
Understanding how and why rates of evolutionary diversification vary is a central issue in evolutionary biology, ecology and biogeography. The concept of adaptive radiation has attracted much interest, but is metaphorical and verbal in nature, making it difficult to quantitatively compare different evolutionary lineages or geographic regions. In addition, the causes of evolutionary stasis are relatively neglected. Here we review the central concepts in the evolutionary diversification literature and bring these together by proposing a...

Data from: Biomass–density relationships of plant communities deviate from the self‐thinning rule due to age structure and abiotic stress

Maximiliane Herberich, Sebastian Gayler, Madhur Anand, Katja Tielbörger & Maximiliane Marion Herberich
A pertinent debate in plant ecology centers around the generality of the self-thinning rule. However, studies focused on highly simplified settings such as even-aged monospecific populations or optimal conditions. This neglects the fact that most natural communities, to which the classical self-thinning slope is often applied, are age-structured, composed of multiple species and exposed to various types of abiotic stress. With the help of an individual-based model, we relax these simplified assumptions and systematically test...

Functional diversity of farmland bees across rural-urban landscapes in a tropical megacity

Gabriel Marcacci, Ingo Grass, Vikas S Rao, Shabarish Kumar S, K.B. Tharini, Vasuki Belavadi, Nils Nölke, Teja Tscharntke & Catrin Westphal
Urbanization is a major threat to biodiversity and food security, as expanding cities, especially in the Global South, increasingly compete with natural and agricultural lands. However, the impact of urban expansion on agricultural biodiversity in tropical regions is overlooked. Here we assessed how urbanization affects the functional response of farmland bees, the most important pollinators for crop production. We sampled bees across three seasons in 36 conventional vegetable-producing farms spread along an urbanization gradient in...

Environmental heterogeneity predicts global species richness patterns better than area

Kristy Udy, Matthias Fritsch, Katrin Meyer, Ingo Grass, Sebastian Hanß, Florian Hartig, Thomas Kneib, Hoger Kreft, Collins Kukuna, Guy Pe'er, Hannah Reininghaus, Britta Tietjen, Clara-Sophie Van Waveren, Kerstin Wiegand & Teja Tscharntke
Aim: It is widely accepted that biodiversity can be determined by niche-relate processes and by pure area effects from local to global scales. Their relative importance, however, is still disputed, and empirical tests are still surprisingly scarce at the global scale. We compare the explanatory power of area and environmental heterogeneity as a proxy for niche-related processes as drivers of native mammal species richnessworldwide and with biogeographical regions. Location: Global Time Period: Data was collated...

Data from: Middle Bronze Age land use practices in the north-western Alpine foreland – A multi-proxy study of colluvial deposits, archaeological features and peat bogs

Sascha Scherer, Benjamin Höpfer, Katleen Deckers, Elske Fischer, Markus Fuchs, Ellen Kandeler, Eva Lehndorff, Johanna Lomax, Sven Marhan, Elena Marinova, Julia Meister, Christian Poll, Humay Rahimova, Manfred Rösch, Kristen Wroth, Julia Zastrow, Thomas Knopf, Thomas Scholten & Peter Kühn
This paper aims to reconstruct Middle Bronze Age (MBA) land use practices in the north-western Alpine foreland (SW Germany, Hegau). We used a multi-proxy approach including the biogeochemical proxies from colluvial deposits in the surrounding of the well-documented settlement site of Anselfingen and offsite pollen data from two peat bogs. This approach allowed in-depth insights into the MBA subsistence economy and shows that the MBA in the north-western Alpine foreland was a period of establishing...

Negative impact of roadside mowing on arthropod fauna and its reduction with arthropod-friendly mowing technique

Johannes Steidle, Thomas Kimmich, Michael Csader & Oliver Betz
This dataset contains data from the paper: “Steidle, J. L.M., Kimmich, T., Csader, M. Betz, O. 2021. Negative impact of roadside mowing on arthropod fauna and its reduction with “arthropod-friendly” mowing technique. Journal of Applied Entomology.” The study investigates the impact of a conventional mowing head ("MK1200") and a supposedly "insects-friendly" mowing head ("Eco 1200") during roadside mowing on the arthropod fauna. Mowing with a conventional mowing head caused considerable losses in arthropods, ranging from...

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...

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....

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...

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...

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...

Khondokar Humayun Kabir, Andrea Knierim, Ataharul Chowdhury & Dietrich Darr
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...

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...

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: Comparison of biometrical models for joint linkage association mapping

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 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: 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...

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: 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...

Sequestration of defenses against predators drives specialized host plant associations in preadapted milkweed bugs (Heteroptera: Lygaeinae)

Georg Petschenka, Rayko Halitschke, Tobias Züst, Anna Roth, Sabrina Stiehler, Linda Tenbusch, Christoph Hartwig, Juan Francisco Moreno Gámez, Robert Trusch, Jürgen Deckert, Kateřina Chalušová, Andreas Vilcinskas & Alice Exnerová
Host plant specialization across herbivorous insects varies dramatically, but while the molecular mechanisms of host-plant adaptations are increasingly known, we often lack a comprehensive understanding of the selective forces that favor specialization. The milkweed bugs (Heteroptera: Lygaeinae) are engaged in ancestrally specialized associations with plants of the Apocynaceae from which they commonly sequester cardiac glycosides for defense, facilitated by resistant Na+/K+-ATPases and adaptations for transport, storage and discharge of toxins. Here, we show that three...
