Data from: Species pools and environmental sorting control different aspects of plant diversity and functional trait composition in recovering grasslands

Timo Conradi & Johannes Kollmann
Succession theory argues that the taxonomic and functional structure of assembling communities is regulated by the interplay of local environmental conditions and regional factors such as available species pools or landscape configurations that moderate dispersal. Yet, the relative importance of these factors and whether they control different aspects of community structure, for example species diversity or the composition of plant traits, is not well understood. This limits predictions of spatial variation in successional outcomes. We...

Data from: Mechanistic model of evolutionary rate variation en route to a nonphotosynthetic lifestyle in plants

Susann Wicke, Kai F. Müller, Claude W. DePamphilis, Dietmar Quandt, Sidonie Bellot & Gerald M. Schneeweiss
Because novel environmental conditions alter the selection pressure on genes or entire subgenomes, adaptive and nonadaptive changes will leave a measurable signature in the genomes, shaping their molecular evolution. We present herein a model of the trajectory of plastid genome evolution under progressively relaxed functional constraints during the transition from autotrophy to a nonphotosynthetic parasitic lifestyle. We show that relaxed purifying selection in all plastid genes is linked to obligate parasitism, characterized by the parasite’s...

Ilse R. Geijzendorffer, Stefano Targetti, Manuel K. Schneider, Dick J. Brus, Philippe Jeanneret, Robert H. G. Jongman, Martin Knotters, Davide Viaggi, Siyka Angelova, Michaela Arndorfer, Debra Bailey, Katalin Balzacs, András Báldim, Marion M. B. Bogers, Robert G.H. Bunce, Jean-Philippe Choisis, Peter Dennis, Sebastian Eiter, Wendy Fjellstad, Jürgen F. Friedel, Tiziano Gomiero, Arjan Griffioen, Max Kainz, Anikó Kovács-Hostyánszki, Gisela Lüscher … & András Báldi
To evaluate progress on political biodiversity objectives, biodiversity monitoring provides information on whether intended results are being achieved. Despite scientific proof that monitoring and evaluation increase the (cost) efficiency of policy measures, cost estimates for monitoring schemes are seldom available, hampering their inclusion in policy programme budgets. Empirical data collected from 12 case studies across Europe were used in a power analysis to estimate the number of farms that would need to be sampled per...

Data from: Resource availability determines the importance of niche-based vs. stochastic community assembly in grasslands

Timo Conradi, Vicky M. Temperton & Johannes Kollmann
Niche-based selection and stochastic processes can operate simultaneously to generate spatial and temporal variation in species composition. Yet, the conditions under which ecological dynamics are dominated by niche-based vs. stochastic processes are poorly understood. Using a field experiment in early-successional temperate grassland and null models of beta diversity, this study investigates the effects of soil nutrient supply on the relative importance of niche-based selection vs. stochastic dynamics for variation in species composition among sites. Nutrient...

Data from: Epigenetic mapping of the Arabidopsis metabolome reveals mediators of the epigenotype-phenotype map

Rik Kooke, Lionel Morgado, Frank FM Becker, Henriette Van Eekelen, Rashmi Hazarika, Qunfeng F Zheng, Ric CH De Vos, Frank Johannes & Joost JB Keurentjes
Identifying the sources of natural variation underlying metabolic differences between plants will enable a better understanding of plant metabolism and provide insights into the regulatory networks that govern plant growth and morphology. So far, however, the contribution of epigenetic variation to metabolic diversity has been largely ignored. In the present study, we utilized a panel of Arabidopsis thaliana epigenetic recombinant inbred lines (epiRILs) to assess the impact of epigenetic variation on the metabolic composition. Thirty...

Data from: Does metabolism constrain bird and mammal ranges and predict shifts in response to climate change?

Lauren B. Buckley, Imran Khaliq, David L. Swanson & Christian Hof
Mechanistic approaches for predicting the ranges of endotherms are needed to forecast their responses to environmental change. We test whether physiological constraints on maximum metabolic rate and the factor by which endotherms can elevate their metabolism (metabolic expansibility) influence cold range limits for mammal and bird species. We examine metabolic expansibility at the cold range boundary (MECRB) and whether species’ traits can predict variability in MECRB and then use MECRB as an initial approach to...

Data from: Explaining European fungal fruiting phenology with climate variability

Carrie Andrew, Einar Heegaard, Klaus Høiland, Beatrice Senn-Irlet, Thomas W. Kuyper, Irmgard Krisai-Greilhuber, Paul M. Kirk, Jacob Heilmann-Clausen, Alan C. Gange, Simon Egli, Claus Bässler, Ulf Büntgen, Lynne Boddy & Håvard Kauserud
Here we assess the impact of geographically dependent (latitude, longitude and altitude) changes in bioclimatic (temperature, precipitation and primary productivity) variability on fungal fruiting phenology across Europe. Two main nutritional guilds of fungi, saprotrophic and ectomycorrhizal, were further separated into spring and autumn fruiters. We used a path‐analysis to investigate how biogeographic patterns in fungal fruiting phenology coincided with seasonal changes in climate and primary production. Across central to northern Europe, mean fruiting varied by...

Data from: Habitat diversity and connectivity govern the conservation value of restored aquatic floodplain habitats

Joachim Pander, Melanie Mueller & Juergen Geist
Floodplains have been strongly altered by human activities such as channelization and other river regulations. Globally, there is a growing interest in their restoration because of an increasing understanding of the ecological importance of these habitats for feeding, spawning, nursery or overwintering of aquatic species. In this study, a large floodplain restoration project of the upper Danube River was used to investigate colonization and succession patterns of fish, macroinvertebrates, macrophytes and periphyton in relation to...

Niina Zuber, Severin Kacianka, Alexander Pretschner & Julian Nida-Rümelin
Wie trifft man eine ethisch richtige Entscheidung? Aufgrund des zunehmenden Einsatzes von Softwaresystemen in immer mehr gesellschaftlichen Bereichen kommt dieser Frage bei der Entwicklung von Softwaresystemen eine wachsende Bedeutung zu. Ethische Entscheidungen, die sich auch in Algorithmen abbilden, haben durch ihre Anwendung im Maschinellen Lernen oder in autonomen Systemen oft Auswirkungen auf sehr viele Menschen. Es ist daher wichtig, dass Entscheidungen, die das Design der Softwareanwendung bedingen, klar argumentiert und nachvollziehbar sind. Derzeit gibt es...

Historical biogeography of Vochysiaceae reveals an unexpected perspective of plant evolution in the Neotropics

Deise Josely Pereira Goncalves, Gustavo H. Shimizu, Edgardo M. Ortiz, Robert K. Jansen & Beryl B. Simpson
PREMISE OF THE STUDY: Despite the fast pace of exploration of the patterns and processes influencing Neotropical plant hyperdiversity, taxa explored are mostly from large groups that are widely distributed, morphologically diverse or economically important. Vochysiaceae is an example of an undersampled taxon, providing an excellent system for investigating Neotropical biogeography. We present a phylogenomic-based hypothesis of species relationships in Vochysiaceae to investigate its evolutionary history through space and time. METHODS: We inferred a phylogeny...

Satellite-based habitat monitoring reveals long-term dynamics of deer habitat in response to forest disturbances

Julian Oeser, Marco Heurich, Cornelius Senf, Dirk Pflugmacher & Tobias Kuemmerle
Disturbances play a key role in driving forest ecosystem dynamics, but how disturbances shape wildlife habitat across space and time often remains unclear. A major reason for this is a lack of information about changes in habitat suitability across large areas and longer time periods. Here, we use a novel approach based on Landsat satellite image time series to map seasonal habitat suitability annually from 1986 to 2017. Our approach involves characterizing forest disturbance dynamics...

Biomarkers in urinary tract infections – which ones are suitable for diagnostics and follow-up?

József Horváth, Björn Wullt, Kurt G. Naber & Béla Köves
Introduction: Urinary tract infections (UTIs) are one of the most common infections worldwide. Under special circumstances, clinicians must rely on laboratory findings, which might have a weak predicting value, misguiding the practitioners and leading to incorrect diagnosis and overuse of antibiotics. Therefore, there is an urgent need for reliable biomarkers in UTIs. Methods: We performed a literature search for biomarkers used in UTIs from January 1999 until May 2020. We used “urinary tract infection” and...

Data from: Systematics of the giant sedges of Carex sect. Rhynchocystis (Cyperaceae) in Macaronesia with description of two new species

Monica Miguez, Pedro Jimenez-Mejias, Carmen Benitez-Benitez, Hanno Schaefer & Santiago Martín-Bravo
Populations of Carex sect. Rhynchocystis (Cyperaceae) from the Macaronesian archipelagos (Azores and Madeira) have traditionally been treated either as a variety of the widely distributed Western Palearctic C. pendula, or directly synonymized under it. However, recent phylogenetic studies have shown that Azorean populations of C. pendula display a certain degree of differentiation from mainland plants, while the phylogenetic relationships of Madeiran populations remain unclear. Here we perform an integrated systematic study focused on the Macaronesian...

1. Agricultural intensification is one of the main drivers of species loss worldwide, but there is still a lack of information about its effect on functional diversity of arable weeds communities. 2. Using a large scale pan European study including 786 fields within 261 farms from eight countries, we analysed differences in the taxonomic and functional diversity of arable weeds assemblages across different levels of agricultural intensification in. We estimated weed species frequency in each...

Morphological trait database of saproxylic beetles

Jonas Hagge, Jörg Müller, Tone Birkemoe, Jörn Buse, Rune Haubo Bojesen Christensen, Martin M. Gossner, Axel Gruppe, Christoph Heibl, Andrea Jarzabek-Müller, Sebastian Seibold, Juha Siitonen, João Gonçalo Soutinho, Anne Sverdrup-Thygeson, Simon Thorn & Lukas Drag
The extinction of species is a non-random process, and understanding why some species are more likely to go extinct than others is critical for conservation efforts. Functional trait-based approaches offer a promising tool to achieve this goal. In forests, deadwood-dependent (saproxylic) beetles comprise a major part of threatened species, but analyses of their extinction risk have been hindered by the availability of suitable morphological traits. To better understand the mechanisms underlying extinction in insects, we...

Timescales of motor memory formation in dual-adaptation

Marion Forano
The timescales of adaptation to novel dynamics are well explained by a dual-rate model with slow and fast states. This model can predict interference, savings and spontaneous recovery, but cannot account for adaptation to multiple tasks, as each new task drives unlearning of the previously learned task. Nevertheless, in the presence of appropriate contextual cues, humans are able to adapt simultaneously to opposing dynamics. Consequently this model was expanded, suggesting that dual-adaptation occurs through a...

Data for Diniz et al. (2022) Changing the main course: strong bat visitation to the ornithophilous mistletoe Psittacanthus robustus (Loranthaceae) in a Neotropical savanna (Biotropica)

Ugo Mendes Diniz, Nina Fischer & Ludmilla Aguiar
The Neotropical genus Psittacanthus comprises mostly specialized ornithophilous mistletoes, with rare exceptions. Psittacanthus robustus is a common ornithophilous species from the South American savannas whose bright-yellow flowers secrete copious diluted nectar. Due to a three-day-long anthesis and a short, non-restrictive floral tube, we suggest that the species also serves as a resource for flower-visiting bats. In a Cerrado area in central Brazil, we investigated the usage of the species by bats through systematic bat captures...

Data from: Foliar herbivory creates subtle soil legacy effects that alter future herbivores via changes in plant community biomass allocation

Robin Heinen
Plants leave legacy effects in the soil they grow in, which can drive important vegetation processes, including productivity, community dynamics and species turnover. Plants at the same time also face continuous pressure posed by insect herbivores. Given the intimate interactions between plants and herbivores in ecosystems, plant identity and herbivory are likely to interactively shape soil legacies. However, the mechanisms that drive such legacy effects on future generations of plants and associated herbivores are little...

Dataset: Effect of flower identity and diversity on reducing aphid populations via natural enemy communities

Sharon Zytynska, Moritz Eicher, Robin Fahle & Wolfgang Weisser
This dataset contains data from the paper: Zytynska SE, Eicher M, Fahle R, Weisser W. Effect of flower identity and diversity on reducing aphid populations via natural enemy communities. Ecology and Evolution. Floral plantings are often used in agriculture to attract pollinator communities but they also play an important role in recruiting and establishing natural communities for natural pest control. Inconsistent effects of floral plantings for pest control may be a result of an absence...

Anschauliche Wege zum Größenvergleich von Brüchen

Frank Reinhold & Kristina Reiss
Bruchrechnen stellt für Schülerinnen und Schüler eine zum Teil erhebliche Her-ausforderung beim Mathematiklernen in der Sekundarstufe dar. Gerade beim Größenvergleich herrschen häufig typische Fehler vor. Dafür gibt es unterschied-liche Erklärungsansätze, etwa den Rückgriff auf Konzepte natürlicher Zahlen – wie etwa die Existenz eines eindeutigen Nachfolgers – die im Zahlbereich der ra-tionalen Zahlen ihre Tragfähigkeit verlieren. Ein Fokus auf den Vergleich mittels einer regelbasierten Gleicher-Nenner-Strategie, in der der Vergleich rein durch die Anwendung einer formalen und...

FASTA sequences of 6 different proteins of SARS-CoV-2

Umama Khan, & Pinky Debnath
The acute respiratory disease induced by the severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) has become a global epidemic in just less than a year by the first half of 2020. The subsequent efficient human-to-human transmission of this virus eventually affected millions of people worldwide. The virulence of the SARS-CoV-2 is mostly regulated by its proteins but very little is known about the protein structures and functionalities. Therefore, the main purpose of this study is to learn...
