GeoLaB - Geothermal Laboratory in the Crystalline Basement

Thomas Kohl , Eva Schill , Judith Bremer , Günter Zimmermann , Olaf Kolditz & Ingo Sass
In Central Europe, the largest geothermal potential resides in the crystalline basement rock with important hotspots in tectonically stressed areas. To better harvest this energy form under sustainable, predictable and efficient conditions, new focused, scientific driven strategies are needed. Similar to other geo-technologies, the complex processes in the subsurface need to be investigated in large-scale facilities to ensure environmental sustainability. The proposed new underground research laboratory GeoLaB (Geothermal Laboratory in the Crystalline Basement) will address...

Data from: Resource supply and organismal dominance are associated with high secondary production in temperate agricultural streams

Romy Wild, Björn Gücker, Markus Weitere & Mario Brauns
Agricultural land use affects the environmental and biological characteristics of stream ecosystems through multiple pathways including nutrient and pesticide contamination, riparian clear-cutting, and hydromorphological degradation. These changes in the abiotic environment can have a direct effect on the productivity of macroinvertebrate communities through environmental filtering and via altered resource conditions encompassing a shift from allochthonous to autochthonous primary production and changes in elemental stoichiometry and food quality. Additionally, macroinvertebrate productivity can be affected indirectly via...

Katrin Wendt-Potthoff, Claudia Drago, Hendrik Füser, Friederike Gabel, Sebastian Höss, Jongsma Rense, Lukas Kruckenfellner, Rico Leiser, Diana Michler-Kozma, Bodo Philipp, Marie-Theres Rauchschwalbe, Corinna Voelkner & Guntram Weithoff
Die Verbreitung von Mikroplastik in Flüssen verdeutlicht, dass sich Plastik nicht nur im Meer, sondern auch in Binnengewässern nachweisen lässt. Wichtige und bisher wenig untersuchte Kompartimente des Gewässersystems sind Talsperren und Stauhaltungen, deren Funktion im Projekt MikroPlaTaS untersucht wurde. Da sich Mikroplastik auf dem Gewässergrund ablagern kann, stellen Talsperren und Staubereiche mögliche Senken für Mikroplastik dar. Das Verbundprojekt analysierte zum einen das Verhalten und Vorkommen von Mikroplastik in diesen strömungsberuhigten Fließgewässerbereichen. Besonders interessant war dabei...

Plant cover and plant-pollinator interactions in Central European grasslands (Poland/Czech Republic)

Demetra Rakosy, Elena Motivans, Valentin Ştefan, Arkadiusz Nowak, Sebastian Świerszcz, Reinart Feldmann, Elisabeth Kühn, Costanza Geppert, Neeraja Venkataraman, Anna Sobieraj-Betlińska, Anita Grossmann, Wiktoria Rojek, Katarzyna Pochrząst, Magdalena Cielniak, Anika Kirstin Gathof, Kevin Baumann & Tiffany Marie Knight
Complex socio-economic, political and demographic factors have driven the increased conversion of Europe’s semi-natural grasslands to intensive pastures. This trend is particularly strong in some of the most biodiverse regions of the continent, such as Central and Eastern Europe. Intensive grazing is known to decrease species diversity and alter the composition of plant and insect communities. Comparatively little is known, however, about how intensive grazing influences plant functional traits related to pollination and the structure...

Pore-scale modeling of acid etching in a carbonate fracture

Renchao Lu , Xing-yuan Miao , Olaf Kolditz & Haibing Shao
Acid fracturing technique has been widely used in the oil and gas industry for improving the carbonate reservoir permeability. In recent years this chemical stimulation technique is borrowed from the oil and gas industry, employed in the enhanced geothermal systems at Groß Schönebeck, Germany (Zimmermann et al., 2010), and at Soultz-sous-Forêts, France (Portier et. al., 2009). In principle, acid fracturing technique utilizes strong acids that react with acid-soluble rock matrix to non-uniformly etch the fracture...

Cross-kingdom interactions and functional patterns of active microbiota matter in governing deadwood decay

Witoon Purahong, Benjawan Tanunchai, Sarah Muszynski, Florian Maurer, Sara Fareed Mohamed Wahdan, Jonas Malter, François Buscot & Matthias Noll
Microbial community members are the primary microbial colonizers and active decomposers of deadwood. This study placed sterilized standardized beech and spruce sapwood specimens on the forest ground of 8 beech- and 8 spruce-dominated forest sites. After 370 days, specimens were assessed for mass loss, nitrogen (N) content and 15N isotopic signature, hydrolytic and lignin-modifying enzyme activities. Each specimen was incubated with bromodeoxyuridine (BrdU) to label metabolically active fungal and bacterial community members, which were assessed...

How to?! Practical knowledge for transformative science – facilitation guidelines for two applications of the Human Scale Development Approach

Salina Spiering nee Centgraf & Maria del Valle Barrera
Multiple methods for transdisciplinary and transformative sciences have been presented and dis-cussed in the literature on sustainability. Wider knowledge however, on how to implement global en-vironmental change is still sough for. We suggest that understanding the practical knowledge with the Aristotelian concept of stechne and phronesis provides important contributions for change. With the present paper we will show the detailed facilitation outlines within the application of the Human Scale Development Approach (HSDA) that was introduced...

Digitalisation and FAIR data are overarching elements in the Helmholtz Research Field Earth and Environment (RF E&E) Program-Oriented Funding Phase IV (PoF IV). Already in the transition years from PoF III to PoF IV (2019/2020) different measures were implemented to facilitate this aim. One of them is the so-called DataHub, with the aim that all Earth System (ES) data that is generated by the RF E&E will be available as FAIR data via a common...

Red in tooth and claw: A review of animal antagonistic roles in movies

Michele Chiacchio & Alessandro Pigoni
1. Although cinema narrative represents a fundamental communication tool in framing public opinion, whether or not a negative representation of certain species in the context of animal-horror movies might increase the attitudinal hostilities toward them, remains an aspect of wildlife perception that is poorly studied. 2. Here, we reviewed online sources from the last 70 years to describe the negative representation of animals roles in horror and disaster movies. Specifically, we described species diversity, how...

Räumliche Prognose der Humuseigenschaften von Waldböden mittels Vis-NIR-Spektroskopie und digitaler Bodenkartierung : Methodenleitfaden für die praktische Anwendung

Karina Becker, Felix Thomas, Rainer Petzold & Ulrike Werban
Humuseigenschaften von Waldböden werden von der forstlichen Standortserkundung den Zustandseigenschaften zugeordnet, da sie relativ rasch veränderbare Standortsmerkmale widerspiegeln. Die Zustandseigenschaften werden durch frühere Nutzungsformen (Streunutzung, Waldweide), Bewirtschaftung (Baumartenwahl, Durchforstungsgrad, Nutzungsintensität und Bestandesalter), anthropogene Stoffeinträge aber auch den voranschreitenden Klimawandel geprägt. Besonders bodenchemische Kennwerte und der Feuchtezustand der Grenzschicht zwischen Mineralboden und Atmosphäre sind von großer Bedeutung für die Beurteilung der aktuellen Nährstoffverfügbarkeit in Verbindung mit einer typischen Vegetationsausbildung. Darüber hinaus können Humuseigenschaften auch als Indikatoren...
