Duccio Rocchini, Sandra Luque, Nathalie Pettorelli, Lucy Bastin, Daniel Doktor, Nicolò Faedi, Hannes Feilhauer, Jean-Baptiste Féret, Giles M. Foody, Yoni Gavish, Sergio Godinho, William E. Kunin, Angela Lausch, Pedro J. Leitao, Matteo Marcantonio, Markus Neteler, Carlo Ricotta, Sebastian Schmidtlein, Petteri Vihervaara, Martin Wegmann & Harini Nagendra
Biodiversity includes multiscalar and multitemporal structures and processes, with different levels of functional organization, from genetic to ecosystemic levels. One of the mostly used methods to infer bio- diversity is based on taxonomic approaches and community ecology theories. However, gathering extensive data in the field is difficult due to logistic problems, especially when aiming at modelling biodiversity changes in space and time, which assumes statistically sound sampling schemes. In this context, airborne or satellite remote...

Data from: Coupled land use and ecological models reveal emergence and feedbacks in socio‐ecological systems

Nicholas W. Synes, Calum Brown, Stephen C. F. Palmer, Greta Bocedi, Patrick E. Osborne, Kevin Watts, Janet Franklin & Justin M. J. Travis
Understanding the dynamics of socio‐ecological systems is crucial to the development of environmentally sustainable practices. Models of social or ecological sub‐systems have greatly enhanced such understanding, but at the risk of obscuring important feedbacks and emergent effects. Integrated modelling approaches have the potential to address this shortcoming by explicitly representing linked socio‐ecological dynamics. We developed a socio‐ecological system model by coupling an existing agent‐based model of land‐use dynamics and an individual‐based model of demography and...

Oxygenated polycyclic aromatic hydrocarbon (OPAH) and polycyclic aromatic hydrocarbon (PAH) concentrations in soils with soil properties: A global data set

Wolfgang Wilcke, Moritz Bigalke, Chong Wei, Yongming Han & Benjamin Musa Bandowe
The hazardous oxygenated polycyclic aromatic hydrocarbons (OPAHs) originate from combustion (primary sources) or post-emission conversion of PAHs (secondary sources). We evaluated the global distribution of up to 15 OPAHs in 195 mineral topsoils from 33 study sites (covering 52°N-47°S, 71°W-118°E), to identify indications of primary or secondary sources of OPAHs. The sums of the (frequently measured 7 and 15) OPAH concentrations correlated with those of the S16EPA-PAHs. The relationship of the S16EPA-PAHs concentrations with the...

Au uniaxial compression in x-direction 10 % engineering strain

Wolfram G. Nöhring, Adam R. Hinkle & Lars Pastewka
This surface is the result of a Molecular Dynamics simulation of uni-axial compression of single crystal Au. The initial configuration was an Au cube with side length 100 nm. The x- and y-directions of the simulation cell were parallel to the [-110] and [-1-12] directions of the crystal, respectively. The z-direction was parallel to the [111] crystal direction. The x- and y-directions were periodic, but the z-direction was free, hence the crystal had free surfaces...

DEEP-TEE Phase 2

The seismological experiment in and around the East Eifel Volcanic Field ( Germany) DEEP-TEE was continued in 2017. Following two unusually deep micro-earthquakes in September 2013 (about 40 km depth) a seismic network was installed to record more local seismic events in order to better understand the seismicity and dynamics of this region in phase I of this experiment. Phase II of DEEP-TEE experiment was motivated due the recordings of several deep low-frequency (DLF) events...

Mediterranean Karst Aquifer Map 1:5,000,000 (MEDKAM)

Julian Xanke, Nico Goldscheider, Bakalowicz Michel, Juan Antonio Barberá, Stefan Broda, Zhao Chen, Mohamed Ghanmi, Günther Andreas, A. Hartmann, Hervé Jourde, Tanja Liesch, Mudarra Matías, Marco Petitta, Natasa Ravbar & Zoran Stevanovic
Karst aquifers constitute important freshwater resources, but are challenging to manage and to protect, because of their unique hydraulic structure and behaviour, representing continuous challenges for research and development. Karst aquifers are widespread and contribute to freshwater supply of most Mediterranean countries and many cities are supplied by karst water, e.g., Rome, Vienna, Montpellier and Beirut. These land surfaces correspond to the main recharge zones of karst aquifers, which are often hydraulically connected over large...

Highly Sensitive Fluorescence Response to Inclusion Complex Formation of Berberine Alkaloid with Cucurbit[7]uril

Mónika Megyesi, László Biczók & István Jablonkai
The effect of inclusion complex formation on the fluorescence properties of berberine, a clinically important natural alkaloid, was studied using cucurbit[7]uril as macrocyclic host compound. The formation of a very stable 1:1 inclusion complex led to about 500-fold fluorescence intensity enhancement, which facilitated the detection of berberine even below nanomolar concentration. Addition of NaCl caused a significant change in the association constant and the fluorescence characteristics of the complex, whereas the variation of the anion...

Data from: Three-dimensional reconstructions come to life – interactive 3D PDF animations in functional morphology

Thomas Van De Kamp, Tomy Dos Santos Rolo, Patrik Vagovič, Tilo Baumbach & Alexander Riedel
Digital surface mesh models based on segmented datasets have become an integral part of studies on animal anatomy and functional morphology; usually, they are published as static images, movies or as interactive PDF files. We demonstrate the use of animated 3D models embedded in PDF documents, which combine the advantages of both movie and interactivity, based on the example of preserved Trigonopterus weevils. The method is particularly suitable to simulate joints with largely deterministic movements...

Data from: Molecular dynamics investigation of gluazo, a photo-switchable ligand for the glutamate receptor GluK2

Yanan Guo, Tino Wolter, Tomáš Kubař, Martin Sumser, Dirk Trauner & Marcus Elstner
Photochromic ligands (PCLs), defined as photoswitchable molecules that are able to endow native receptors with a sensitivity towards light, have become a promising photopharmacological tool for various applications in biology. In general, PCLs consist of a ligand of the target receptor covalently linked to an azobenzene, which can be reversibly switched between two configurations upon light illumination. Gluazo, as a PCL that targets excitatory amino acid receptors, in its dark-adapted trans iso-form was characterized to...

Quartet-based computations of internode certainty provide robust measures of phylogenetic incongruence

Xiaofan Zhou, Sarah Lutteropp, Lucas Czech, Alexandros Stamatakis, Moritz Von Looz & Antonis Rokas
Incongruence, or topological conflict, is prevalent in genome-scale data sets. Internode certainty (IC) and related measures were recently introduced to explicitly quantify the level of incongruence of a given internal branch among a set of phylogenetic trees and complement regular branch support measures (e.g., bootstrap, posterior probability) that instead assess the statistical confidence of inference. Since most phylogenomic studies contain data partitions (e.g., genes) with missing taxa and IC scores stem from the frequencies of...

Data from: A taxonomic, functional and phylogenetic perspective on the community assembly of passerine birds along an elevational gradient in southwest China

Xuelian He, Kang Luo, Calum Brown & Luxiang Lin
Integrating multiple-facets of biodiversity to describe spatial and temporal distribution patterns is one way of revealing the mechanisms driving community assembly. We assessed the species, functional and phylogenetic composition and structure of passerine bird communities along an elevational gradient both in wintering and breeding seasons in the Ailao Mountains, southwest China, in order to identify the dominant ecological processes structuring the communities and how these processes change with elevation and season. Our research confirms that...

Data from: Differing impacts of two major plant invaders on urban plant-dwelling spiders (Araneae) during flowering season

Tobias Bauer, Daria Bäte, Fabian Kempfer & Jens Schirmel
The dataset contains spider (Araneae) specimen numbers collected from flowering invasive American goldenrod (Solidago canadensis/gigantea) and invasive Himalayan balsam (Impatiens glandulifera) stands occuring naturally in urban areas of the city of Karlsruhe, Germany. Corresponding plots with native ruderalized vegetation in direct vicinity of each invaded plot were used as a comparison plot, resulting in a fully paired design for each plant invader study. An additional column represents potential non-araneae prey items collected together with the...

Data from: EPA-ng: massively parallel evolutionary placement of genetic sequences

Pierre Barbera, Alexey M. Kozlov, Lucas Czech, Benoit Morel, Diego Darriba, Tomas Flouri & Alexandros Stamatakis
Next Generation Sequencing (NGS) technologies have led to a ubiquity of molecular sequence data. This data avalanche is particularly challenging in metagenetics, which focuses on taxonomic identification of sequences obtained from diverse microbial environments. Phylogenetic placement methods determine how these sequences fit into anevolutionary context. Previous implementations of phylogenetic placement algorithms, such as the Evolutionary Placement Algorithm (EPA) included in RAxML, or pplacer, are being increasingly used for this purpose. However, due to the steady...

This supplement aims to substantiate and expand our comments made in the Letter to the Editor. This format as a separate document was necessary due to the complexity of the issues raised in our comments vis-à-vis the word limit of PNAS Letters (500 words). The text elaborates on individual concerns raised in the letter and also adds new aspects on the research quality that have not yet been discussed in the letter. Moreover, the supplement...

Mikroseismisches Kandel Elztal Experiment

The aim of the microseismic Kandel-Elztal experiment (MiKaEl-Ex) is to continuously record the micro-earthquakes with a highly sensitive measuring network. From this measurement data, the micro-earthquake signals will then be identified from the background noise using innovative methods based on artificial intelligence. Then the arrival time of the earthquakes waves are used to calculate the exact location of their sources in the interior of the earth. In this way, potential active faults are found and...

Electrostatic interactions contribute to the control of intramolecular thiol–disulfide isomerization in a protein

Tomáš Kubař, Denis Maag, Marina Putzu, Claudia L. Goméz-Flores, Frauke Gräter & Marcus Elstner
The role of structural factors and of electrostatic interactions with the environment on the outcome of thiol–disulfide exchange reactions were investigated in a mutated immunoglobulin domain (I27*) under mechanical stress. An extensive ensemble of molecular dynamics trajectories was generated by means of QM/MM simulations for a total sampling of 5.7 μs. A significant number of thiol–disulfide exchanges were observed, and the Cys32 thiolate preferred to attack Cys55 over Cys24, in agreement with previous experimental and...

Will forest dynamics continue to accelerate throughout the 21st century in the Northern Alps?

Dominik Thom, Werner Rammer, Patrick Laux, Gerhard Smiatek, Harald Kunstmann, Sebastian Seibold & Rupert Seidl
Observational evidence suggests that forests in the Northern Alps are changing at an increasing rate as a consequence of climate change. Yet, it remains unclear whether the acceleration of forest change will continue in the future, or whether downregulating feedbacks will eventually decouple forest dynamics from climate change. Here we studied future forest dynamics at Berchtesgaden National Park, Germany by means of a process-based forest landscape model, simulating an ensemble of 22 climate projections until...

CuZr biaxial compression 20% engineering strain

Wolfram G. Nöhring, Adam R. Hinkle & Lars Pastewka
This surface is the result of a Molecular Dynamics simulation of bi-axial compression of a CuZr (50% Cu, 50% Zr) metallic glass. The initial configuration was a CuZr cube with side length 100 nm. The glass had been produced by quenching from the melt at a rate of 1e11 K/s under fully periodic boundary conditions. In the compression simulation, the x- and y-directions were periodic, but the z-direction was free, hence the glass had free...
