Development of the arable vegetation 23 years after conversion from conventional to organic farming – experiences from a farm-scale case studyin southern Germany

Harald Albrecht, Sandra Mademann & Helmut Weikl
Recent meta-analyses assessing the impact of organic farming on plant species diversity showed that positive effects mainly occurred at a small scale while benefits at the farm or landscape level were less pronounced. The studies also detected that common species were more favored by organic farming than rare ones. In a farm scale study in southern Bavaria, Germany, we analyzed how the conversion to organic farming changed arable plant communities over a 23-years period and...

Effects of different restoration treatments on long-term development of plant diversity and functional trait composition in calcareous grasslands

Stefan Hofmann, Timo Conradi, Kathrin Kiehl & Harald Albrecht
Establishment of calcareous grassland on ex-arable fields by introducing target species is one of the most frequently used methods to restore the species assemblages of this highly endangered habitat type. The present study evaluates the long-term success of calcareous grassland restoration on former arable land in the vicinity of one of the oldest nature reserves in Bavaria, the “Garchinger Heide”. The restoration experiment combined different measures like topsoil removal, transfer of freshly cut seed-containing hay...

Data for: Topological defects produce kinks in biopolymer filament bundles

Qingda Hu, Maximilian Grill, Elliot Botvinick, Wolfgang Wall, Valentin Slepukhin & Alex Levine
Bundles of stiff filaments are ubiquitous in the living world, found both in the cytoskeleton and in the extracellular medium. These bundles are typically held together by smaller cross-linking molecules. We demonstrate, analytically, numerically, and experimentally, that such bundles can be kinked, that is, have localized regions of high curvature that are long-lived metastable states. We propose three possible mechanisms of kink stabilization: a difference in trapped length of the filament segments between two cross-links,...

Urinary tract infections in patients with renal insufficiency and dialysis – epidemiology, pathogenesis, clinical symptoms, diagnosis and treatment

Jürgen E Scherberich, Reinhard Fünfstück & Kurt G. Naber
Epidemiological studies show an increasing number of patients worldwide suffering from chronic kidney diseases (CKD), which are associated with a risk for progression to end-stage kidney disease (ESKD). CKD patients stage 2–5, patients with regular chronic dialysis treatment (hemo- or peritoneal dialysis), and patients suffering from kidney allograft dysfunction are at high risk to develop infections, e.g. urinary tract infections (UTI) and/or sepsis (urosepsis). These groups show metabolic disturbance, chronic inflammation, and impaired immunocompetence. Escherichia...

Disentangling effects of climate and land use on biodiversity and ecosystem services – a multi-scale experimental design

Sarah Redlich, Jie Zhang, Caryl Benjamin, Maninder Singh Dhillon, Jana Englmeier, Jörg Ewald, Ute Fricke, Cristina Ganuza, Maria Hänsel, Thomas Hovestadt, Johannes Kollmann, Thomas Koellner, Carina Kübert-Flock, Harald Kunstmann, Annette Menzel, Christoph Moning, Wibke Peters, Rebekka Riebl, Thomas Rummler, Sandra Rojas Botero, Cynthia Tobisch, Johannes Uhler, Lars Uphus, Jörg Müller & Ingolf Steffan-Dewenter
1. Climate and land-use change are key drivers of environmental degradation in the Anthropocene, but too little is known about their interactive effects on biodiversity and ecosystem services. Long-term data on biodiversity trends are currently lacking. Furthermore, previous ecological studies have rarely considered climate and land use in a joint design, did not achieve variable independence or lost statistical power by not covering the full range of environmental gradients. 2. Here, we introduce a multi-scale...

Kazak faecal microbiota transplantation induces short-chain fatty acids that promote glucagon-like peptide-1 secretion by regulating gut microbiota in db/db mice

Xue Han, Ye Wang, Peipei Zhang, Manli Zhu, Ling Li, Xinmin Mao, Xiaoting Sha & Linlin Li
Faecal microbiota transplantation (FMT) from Kazak individuals with normal glucose tolerance (KNGT) significantly reduces plasma glycolipid levels in type 2 diabetes mellitus db/db mice. However, the mechanism behind this effect has not been reported. To study the mechanism of improved glycolipid disorders in db/db mice by FMT from a KNGT donor. The normal diet group consisted of db/m mice orally administered 0.2 mL phosphate buffer saline (PBS) (db/m + PBS). For the db/db + PBS...

The long-term effect of low and moderate doses of ionizing radiation on the lens is still a matter of debate and needs to be evaluated in more detail. We conducted a detailed histological analysis of eyes from B6C3F1 mice cohorts after acute gamma irradiation (60Co source; 0.063 Gy/min) at young adult age of 10 weeks with doses of 0.063, 0.125, and 0.5 Gy. Sham irradiated (0 Gy) mice were used as controls. To test for...

Acute radiation syndrome-related gene expression in irradiated peripheral blood cell populations

Patrick Ostheim, Alan Don Mallawaratchy, Thomas Müller, Simone Schüle, Cornelius Hermann, Tanja Popp, Stefan Eder, Stephanie E. Combs, Matthias Port & Michael Abend
In a nuclear or radiological event, an early diagnostic tool is needed to distinguish the worried well from those individuals who may later develop life-threatenFing hematologic acute radiation syndrome. We examined the contribution of the peripheral blood's cell populations on radiation-induced gene expression (GE) changes. EDTA-whole-blood from six healthy donors was X-irradiated with 0 and 4Gy and T-lymphocytes, B-lymphocytes, NK-cells and granulocytes were separated using immunomagnetic methods. GE were examined in cell populations and whole...

A systematic assessment of medical diagnoses preceding the first diagnosis of multiple sclerosis: Supplementary materials

Bernhard Hemmer
Objective: To explore the occurrence of diseases and symptoms in the five years prior to diagnosis in patients with multiple sclerosis (MS) in a case-control study. Methods: Using ambulatory claims data we systematically assessed differences in the occurrence of diseases and symptoms in the five years prior to first diagnosis in patients with MS (n=10,262) as compared to patients with two other autoimmune diseases – Crohn’s disease (n=15,502) and psoriasis (n=98,432) - and individuals without...

Dispersal syndromes are poorly associated with climatic niche differences in the Azorean seed plants

María Leo, Manuel J. Steinbauer, Paulo A. V. Borges, Eduardo B. De Azevedo, Rosalina Gabriel, Hanno Schaefer & Ana M. C. Santos
Aim: Environmental niche tracking is linked to the species ability to disperse. While well investigated on large spatial scales, dispersal constraints also influence small-scale processes and may explain the difference between the potential and the realized niche of species at small-scales. Here we test whether niche size and niche fill differ systematically according to dispersal syndrome within isolated oceanic islands. We expect species with higher dispersal abilities (anemochorous or endozoochorous) will have a higher niche...

Plant diversity across small-scale boundaries

Pia Maria Eibes, Jens Oldeland, Severin David Howard Irl, Alina Twerski, Nicole Kühne & Ute Schmiedel
Questions: Habitat islands are often characterized by the presence of more or less sharp boundaries to adjacent matrix habitats. However, knowledge on boundaries of natural habitat islands is scarce, especially regarding patterns of beta diversity and its two underlying components: species turnover and nestedness. We therefore aim to quantify the effects of fine-scaled and sharp boundaries of quartz islands (quartz-gravel covered soils) on the different components of plant beta diversity and how they are linked...

Schlarb, Michael Schmidt … & Susanne Kadner
Most current patterns of production and consumption follow a linear “extract, produce, consume, dispose” model. According to the Circular Gap Report 2020, the global economy is just 9% circular. This economic model is contributing to a massive transgression of “planetary boundaries” and the destabilisation of ecosystems and factors essential to human life such as the climate system and biodiversity. As a result, there is currently much discussion of a paradigm shift in the industrial value...

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 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...

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...

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...

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...

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...

Public food forest opportunities and challenges in small municipalities

Sarah Coffey, John Munsell, Rico Hübner & Curtis Friedel
The opportunities and challenges associated with public food forest initiatives in small municipalities are understudied compared to large metropolitan counterparts. Research in small population centers is needed to identify and understand factors affecting the growth of public food forests where resources more commonly available in cities often are lacking. To study these factors, we surveyed mayors in Virginia, United States serving communities with populations under 25,000. Out of 176 mayors who received a paper survey...

Relative impacts of gypsy moth outbreaks and insecticide treatments on forest resources and ecosystem: An experimental approach

Benjamin Leroy, Hannes Lemme, Philipp Braumiller, Torben Hilmers, Martin Jacobs, Sophia Hochrein, Sebastian Kienlein, Jörg Müller, Hans Pretzsch, Kilian Stimm, Sebastian Seibold, Jessica Jaworek, W. Andreas Hahn, Stefan Müller-Kroehling & Wolfgang Weisser
Gypsy moth outbreaks cause severe defoliation in Holarctic forests, both in North America where it is invasive, and in its native range in Eurasia. Severe defoliation can hamper timber production and impact ecological communities and processes. Aerial insecticide applications are regularly performed in outbreak areas to mitigate economic losses. These operations can be financially costly and harmful to non-target species and may disrupt species interaction networks. However, replicated studies of the relative impacts of gypsy...
