Data from: Landscape complexity promotes resilience of biological pest control to climate change

Benjamin Feit, Nico Blüthgen, Eirini Daouti, Cory Straub, Michael Traugott & Mattias Jonsson
Increased climate variability as a result of anthropogenic climate change can threaten the functioning of ecosystem services. However, diverse responses to climate change among species (response diversity) can provide ecosystems with resilience to this growing threat. Measuring and managing response diversity and resilience to global change are key ecological challenges. Here, we develop a novel index of climate resilience of ecosystem services, exemplified by calculating the thermal resilience of predator communities providing biological pest control....

Towards a sediment budget of Permo-Triassic successions in the Central European Basin - implications for terrestrial perturbations around the Permian-Triassic Boundary (PTB)

Maryam Mansouri & Matthias Hinderer
Technische Universität Darmstadt, Germany

For the first time, we quantified the erosional pulse around the Permian-Triassic Boundary (PTB) over an entire sedimentary basin. Our GIS-based analysis relies on basin-wide homogenized seismic, sedimentary and stratigraphic data of the Petroleum Geological Atlas of the Southern Permian Basin. We calculated sediment volumes, sediment fluxes and sedimentation rates (SR) averaged over the entire basin from isopach maps of the Rotliegend, the Zechstein, the Lower, Middle and Upper...

Datenschutz und informationelle Selbstbestimmung in der Schule

Franco Rau, Britta Galanamatis, Lars Gerber, Petra Grell, Johannes Konert, Kathrin Rheinländer & Daniel Scholl
Datenschutz und informationelle Selbstbestimmung sind Bestandteile aktueller Leitbilder einer Digitalen Bildung in der Schule. Im Kontext der Schulschließungen und der vorrangigen Nutzung digitaler Medien zeigte sich jedoch, dass Datenschutz weder als Thema noch als Gestaltungsprinzip digitaler Lernumgebungen in der bildungsadministrativen und pädagogisch-praktischen Schulwirklichkeit systematisch verankert ist. Die Diskrepanz zwischen aktuellen Leitbildern einer digitalen Bildung und der sichtbar problematischen Praxis des digitalen Notfalldistanzunterrichts markiert den Ausgangspunkt des Beitrages, der sich der übergeordneten Frage widmet, welche Herausforderungen...

3D geological modeling of graben structures in northern Hesse – concept, methods and first results

Ina Lewin, Rouwen Lehné & Heiner Heggemann
For some years now, the Hessian Agency for Nature Conservation, Environment and Geology (HLNUG) is focusing its 3D-modeling activities on urban areas, aiming to contribute to both integrated modeling and urban planning (e.g., Lehné et al. 2017, Lehné et al. 2013, Budde et al. 2017). Experiences gained in the frame of the project “Darmstadt_3D”, which is delivering the urban subsurface including the technical infrastructure (sewage system, foundations, etc.), now are adopted for a working area...

The Quasi-Other as a Sobject

Larissa Ullmann
This comment on Mark Coeckelbergh’s text “You, robot: on the linguistic construction of artificial others” is about the concrete use of linguistic terms to describe the technical other, the robot, and its relationship to humans. There are many characteristics that a robot can have that are very similar to humans and interpersonal relations, but they are not human, they are quasi-human. This phenomenon is, amongst others, constructed and interpreted linguistically, but on the other hand,...

Tectonic and environmental perturbations at the Permian-Triassic boundary: insights from the Blue Nile River Basin in central Ethiopia

Maryam Mansouri , Matthias Hinderer , Laura Stutenbecker , Guido Meinhold , Enkurie L. Dawit , Jasper Berndt & Robert Bussert
The Blue Nile River Basin contains a thick fluvio-lacustrine sediment succession of Permian to Jurassic age. Its evolution is linked to extensional tectonics during break-up of Pangea in the aftermath of the Carboniferous-Permian glaciation. We collected sandstone samples from several sections in order to study the tectonic evolution and possible impacts of environmental perturbation around the Permian-Triassic boundary. Based on thin-section petrography, bulk-rock geochemistry, heavy mineral spectra, and detrital zircon U-Pb ages we are able...

Reconstruction of Miocene geodynamics in the Central Alps using detrital garnet geochemistry in sandstones of the Swiss foreland basin

Daniela Krieg & Laura Stutenbecker
The geodynamics in the Central Alps during the Miocene were majorly characterized by the exhumation of crystalline basement, the so-called external crystalline massifs. Their exhumation had a major impact on the evolution of relief, distribution of drainage networks and sediment-generation. The timing of their first surficial exposure and their total thickness still remains debated. The Swiss Molasse Basin contains ~35 to 13 Ma old clastic deposits that were mostly derived from the immediate hinterland and...

Data from: Seed dispersal by ungulates as an ecological filter: a trait-based meta-analysis

Aurélie Albert, Alistair G. Auffret, Eric Cosyns, Sara A. O. Cousins, Bram D'Hondt, Carsten Eichberg, Amy E. Eycott, Thilo Heinken, Maurice Hoffmann, Bogdan Jaroszewicz, Juan E. Malo, Anders Mårell, Maarten Mouissie, Robin J. Pakeman, Mélanie Picard, Jan Plue, Peter Poschlod, Sam Provoost, Kiowa Alraune Schulze & Christophe Baltzinger
Plant communities are often dispersal-limited and zoochory can be an efficient mechanism for plants to colonize new patches of potentially suitable habitat. We predicted that seed dispersal by ungulates acts as an ecological filter – which differentially affects individuals according to their characteristics and shapes species assemblages – and that the filter varies according to the dispersal mechanism (endozoochory, fur-epizoochory and hoof-epizoochory). We conducted two-step individual participant data meta-analyses of 52 studies on plant dispersal...

Infinity: Divine Paradigm

Chandrima Christiansen
“In the Beginning was the Word” provides the biblical reference to the word ‘Word,’ and ‘Infinity’ touches upon the traditional philosophical conventions that refer to God as the ‘Infinite’ and the creations of God as the ‘finites.’ Infinity as a technical artefact, engages the mind with its abstractness and metaphorical rendition as in Basic Metaphor of Infinity (BMI), but also with its concreteness as in programming, modelling and topography. ‘Infinity’ as a concept and as...

The Grammar of Things

Alfred Nordmann
This essay for the inaugural issue of Technology and Language programmatically proposes that „technology“ and „language“ are two sides of the same coin and that one cannot talk about one without the other. Everyone agrees that technology cannot be defined as the application of science to the engineering of specific devices. Instead, it includes all the ways in which homo faber has always worked to transform the naturally given world into a technosphere. And everyone...

Standortsuche im Spannungsfeld

Oliver Heidbach, Moritz Ziegler, Sophia Morawietz, Karsten Reiter, Luisa Röckel & Fabrice Cotton
Das gegenwärtige Spannungsfeld der Erdkruste ist eine zentrale Feldgröße für die Beurteilung der Stabilität eines Endlagers. Erreichen die Spannungen einen kritischen Wert, dann versagt das Gestein. Es bilden sich Risse und Brüche, die Wegsamkeiten für Flüssigkeiten und Gase darstellen. Als Folge kann das Endlager undicht werden. Im direkten Bezug dazu stehen die Ausschlusskriterien seismische Aktivität und aktive Störungszonen aus dem Standortauswahlgesetz. Beide sind ein Ausdruck dafür, dass der kritische Wert überschritten wurde.

The Body, the Soul, the Robot: 21st-Century Monism

Kevin Liggieri & Marco Tamborini
The thesis we will defend in the following pages is twofold. First, we indicate two linguistic-cultural turning points in the concept of the robot. The introduction of the body and the soul in the machine has paved the way towards new technical and epistemic possibilities and, thus, it has granted a new conceptual definition of robot. Second, we propose a return to Descartes as a starting point for a reinterpretation and redefinition of the concept...

Hydro-thermal modeling of geothermal energy extraction from Soultz-sous-Forêts, France using supercritical CO2

Mrityunjay Singh , Saeed Mahmoodpour , Kristian Bär & Claire Bossennec
Climate change requires immediate action, and for sustainable development, and uninterrupted energy supply is necessary. Since anthropogenic emission of CO2 in the atmosphere has a major role in climate change, carbon negative energy solutions are the necessity of the time. Geothermal energy is one such renewable source that can assist in achieving an economic solution to low carbon energy. Engineered geothermal systems or enhanced geothermal systems (EGS) are more suitable from an industrial perspective and...

Granulometric and lithologic control on heavy mineral distribution in Alpine fluvial sediment

Ariane Djahansouzi, Laura Stutenbecker, Daniela Krieg & Christoph Glotzbach
Heavy mineral studies are dependent on many variables that should be considered in order to avoid erroneous provenance interpretations. Firstly, sediment transported and deposited by larger rivers is the result of the erosion of several lithological units present in the catchment with potentially differing mineral fertilities. Secondly, possible bias arises from the narrow sand-size window that is typically considered for single-grain analysis in sedimentary provenance studies. Quantifying and understanding the resulting bias is crucial for...

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...

Program and Code

Reiner Hähnle
The nature of computer programs can be characterized from two different viewpoints: as executable artifacts that create signals on a computing device or as pure mathematical objects with a rigorous, unambiguous semantics. To distinguish both usages I use the word “code” for the first and “program” for the second. This distinction is relevant to avoid confusion when discussing notions such as validity or correctness of software. The point is illustrated by refuting a well-known claim...

Arthropod (per year, 2008-2017) and environmental data (climate, land use, land cover) from grasslands used in \"Unravelling insect declines: can space replace time?\", Biology Letters

Michael Staab & Nico Blüthgen
To compare trends in arthropod species numbers between space and time, arthropod data from the sweep net samples (2008-2017) in grasslands were used. We tested whether trends over time are also found within single years (i.e. in space). The dataset contains, pooled per sampling year, arthropod individual numbers (Araneae, Coleoptera, Hemiptera, Orthoptera) and associated environmental data (climate, land use, land cover). This data is only to complement the publication "Unravelling insect declines: can space replace...

Instructing Technology, Technological Instruction: Editorial Introduction

Jens Geisse & Marcel Siegler
The term instruction is multi-layered and used in completely different contexts – from printed user manuals, over explicitly uttered verbal directives to the implicit teaching of forms of conduct by exemplifying them. This issue collects contributions that explore instructions from a philosophical perspective on the relationship between language and technology. The following editorial introduces these contributions and identifies connections between them. Although the contributions in this special issue explore the term instruction from different angles,...

The temporal variability of sediment composition in modern rivers: provenance or grain size signal?

Laura Stutenbecker
The first step in any provenance study is sampling the sediment of interest, which is subject to many potential sources of error. It is nevertheless commonly assumed that one sample of sediment is enough to provide a somewhat “basin-averaged” compositional signal. Spatial or temporal variability of this signal is often not considered. In this study, we test the temporal variability of sediment composition in modern fluvial deposits in four German rivers: the Gersprenz, Modau and...

Climate, volcanoes, and tectonic activity - Their influence on the lower to middle Eocene paleoenvironment on the Sprendlinger Horst (Southwest Germany)

Maryam Moshayedi , Olaf K. Lenz , Jürgen Mutzl , Volker Wilde & Matthias Hinderer
The Werra-Fulda mining district located in Central Germany hosts a world-class deposit of sulfate bearing potash salts. The Permian (Zechstein, ca. 255 Ma) evaporite sequence was intruded by mafic melts in the Neogene resulting in magmatic dykes as well as sill structures frequently observed in the subsurface mining galleries. Furthermore, volcanic rocks intersect the overlaying strata (mainly Buntsandstein and Muschelkalk) at localized spots forming distinct mountains. In this study, samples from subsurface mafic dykes and...

Pre-Variscan (Lower Devonian) deformation of the Silurian magmatic arc of the East Odenwald (Mid-German Crystalline Zone, Variscides)

Henri Paul Meinaß , Wolfgang Dörr & Eckardt Stein
The Böllstein Odenwald is forming a large anticline of mainly pre-Devonian rock in the Mid-German Crystalline Zone (MCGZ). The contact between core and schist envelope of the anticline is well exposed at Weichberg quarry. Metasedimentary rocks of the schist envelope are intruded by granodioritic sills of a Silurian magmatic arc, showing at least two folding phases: Recumbent tight isoclinal folds are overprinted by upright gentle folds. A pegmatite dike, intruding at 411 ±2 Ma (U-Pb...
