Data from: Synergetic use of Sentinel-1 and Sentinel-2 for assessments of heathland conservation status

Johannes Schmidt, Fabian E. Fassnacht, Michael Förster, Sabastian Schmidtlein & Sebastian Schmidtlein
Habitat quality assessments often demand wall-to-wall information about the state of vegetation. Remote sensing can provide this information by capturing optical and structural attributes of plant communities. Although active and passive remote sensing approaches are considered as complementary techniques, they have been rarely combined for conservation mapping. Here, we combined spaceborne multispectral Sentinel-2 and Sentinel-1 SAR data for a remote sensing-based habitat quality assessment of dwarf shrub heathland, which was inspired by nature conservation field...

Plant traits, biotopes and urbanization dynamics explain the survival of endangered urban plant populations

Greg Planchuelo, Ingo Kowarik & Moritz Von Der Lippe
1. With accelerating urbanization, the urban contribution to biodiversity conservation becomes increasingly important. Previous research shows that cities can host many endangered plant species. However, fundamental questions for urban nature conservation remain open: to what extent and where can endangered plant species persist in the long term and which mechanisms underlie population survival? 2. We evaluate the survival of 858 precisely monitored populations of 179 endangered plant species in Berlin, Germany, by assessing population survival...

Natural enemy-herbivore networks along local management and landscape gradients in urban agroecosystems

Stacy Philpott, Azucena Lucatero, Peter Bichier, Monika Egerer, Shalene Jha, Brenda Lin & Heidi Liere
Ecological networks can provide insight into how biodiversity loss and changes in species interactions impact the delivery of ecosystem services. In agroecosystems that vary in management practices, quantifying changes in ecological network structure across gradients of local and landscape composition can inform both the ecology and function of productive agroecosystems. In this study, we examined natural enemy-herbivore co-occurrence networks associated with Brassica oleracea (cole crops), a common crop in urban agricultural systems. Specifically, we investigated...

Neutron study of the topological flux model of hydrogen ions in water ice

J.-U. Hoffmann, K. Siemensmeyer, S. Isakov, D. J. P. Morris, B. Klemke, I. Glavatskyi, K. Seiffert, D. A. Tennant, S. Sondhi & R. Moessner
The familiarity of water ice means we often overlook its non-trivial character illustrated, for example, by the many snowflake morphologies resulting from disordered combinations of covalent and hydrogen bonds between hydrogen and oxygen atoms in water ice’s most common phase (Ih) that keep the H_2 O molecular character. Using neutron diffraction on the flat-cone diffractometer E2 at BER-II, Helmholtz-Zentrum Berlin, we probe the atomic scale configuration in the Ih phase of water ice to test...

Data from: A new squeaker frog (Arthroleptidae: Arthroleptis) from the Cameroon Volcanic Line with redescriptions of Arthroleptis adolfifriederici Nieden, 1911 \"1910\" and A. variabilis Matschie, 1893

David C. Blackburn, Legrand N Gonwouo, Raffael Ernst & Mark-Oliver Rödel
We describe a new species of squeaker frog (Arthroleptis) from Mt. Manengouba in southwestern Cameroon. The new species is distinguished from other Cameroonian Arthroleptis by moderately larger body size; a darkened throat and posterior thigh, both with many white spots; and, in females, a fourth finger longer than the first and second fingers. This species corresponds to a Cameroonian taxon previously identified as Arthroleptis adolfifriederici but which has been long recognized as distinct. Multivariate morphometric...

Data from: Stoichiometric imbalances between detritus and detritivores are related to shifts in ecosystem functioning

André Frainer, Jérémy Jabiol, Mark O. Gessner, Andreas Bruder, Eric Chauvet, Brendan McKie & Brendan G. McKie
How are resource consumption and growth rates of litter-consuming detritivores affected by imbalances between consumer and litter C:N:P ratios? To address this question, we offered leaf litter as food to three aquatic detritivore species, which represent a gradient of increasing body N:P ratios: a crustacean, a caddisfly and a stonefly. The detritivores were placed in microcosms and submerged in a natural stream. Four contrasting leaf species were offered, both singly and in two-species mixtures, to...

Interest in insect die-off and intention for action using Google trends

Esther Felgentreff, Sascha Buchholz & Tanja Straka
1. The publication of “More than 75 percent decline over 27 years in total flying insect biomass in protected areas” by Hallmann et al. in October 2017 gained vast media coverage in Germany. The insect crisis as conservation topic has received little attention among the public before, but since media influences people’s awareness, we investigated i) whether the study publication induced increased awareness among the German public for insect die-off, and ii) whether it contributed...

Data from: Genome mining reveals the genus Xanthomonas to be a promising reservoir for new bioactive non-ribosomally synthesized peptides

Monique Royer, Ralf Koebnik, Mélanie Marguerettaz, Valérie Barbe, Guillaume P. Robin, Chrystelle Brin, Sébastien Carrere, Camila Gomez, Manuela Hügelland, Ginka H. Völler, Julie Noëll, Isabelle Pieretti, Saskia Rausch, Valérie Verdier, Stéphane Poussier, Philippe Rott, Roderich D. Süssmuth & Stéphane Cociancich
Background: Various bacteria can use non-ribosomal peptide synthesis (NRPS) to produce peptides or other small molecules. Conserved features within the NRPS machinery allow the type, and sometimes even the structure, of the synthesized polypeptide to be predicted. Thus, bacterial genome mining via in silico analyses of NRPS genes offers an attractive opportunity to uncover new bioactive non-ribosomally synthesized peptides. Xanthomonas is a large genus of Gram-negative bacteria that cause disease in hundreds of plant species....

Data from: Timing of head movements is consistent with energy minimization in walking ungulates

David M. Loscher, Fiete Meyer, Kerstin Kracht & John A. Nyakatura
Many ungulates show a conspicuous nodding motion of the head when walking. Until now, the functional significance of this behaviour remained unclear. Combining in vivo kinematics of quadrupedal mammals with a computer model, we show that the timing of vertical displacements of the head and neck is consistent with minimizing energy expenditure for carrying these body parts in an inverted pendulum walking gait. Varying the timing of head movements in the model resulted in increased...

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...

Data from: From welcome culture to welcome limits? Uncovering preference changes over time for sheltering refugees in Germany

Ulf Liebe, Jürgen Meyerhoff, Maarten Kroesen, Caspar Chorus & Klaus Glenk
Europe recently experienced a large influx of refugees, spurring much public debate about the admission and integration of refugees and migrants into society. Previous research based on cross-sectional data found that European citizens generally favour asylum seekers with high employability, severe vulnerabilities, and Christians over Muslims. These preferences and attitudes were found to be homogeneous across countries and socio-demographic groups. Here, we do not study the general acceptance of asylum seekers, but the acceptance of...

Gardener demographics, experience, and motivations drive differences in plant species richness and composition in urban gardens

Stacy Philpott, Monika Egerer, Peter Bichier, Hamutahl Cohen, Roseann Cohen, Heidi Liere, Shalene Jha & Brenda Lin
Urban agriculture has received considerable attention for its role in supporting biodiversity and ecosystem services, and health and well-being for growing urban populations. Urban gardens managed with agroecological practices and higher plant diversity support more biodiversity and may support higher crop production. Plant selection in gardens is a function of temperature and environmental conditions and also depends on gardener socio-demographic characteristics, motivations for gardening, and gardening experience. In this study, we examined how plant richness...

Data from: Exploring the biotic homogenisation and diversity resistance hypotheses: the understorey of non-native and native woodland canopies in three urban areas of Europe

Exploring the biotic homogenisation and diversity resistance hypotheses by assessing the effect of non-native black locust canopy on understorey species turnover. Location: Berlin, the Venetian metropolitan area, and Rome. We modelled the zeta (ζ) expression of diversity to compare the understorey species turnover between the non-native black locust and native woodland canopies across multiple sites and through predictors of anthropogenic pressure (road and built-up density) and interior conditions (tree basal area and mean height). In...

Supplement to: Nano-optical designs for high efficiency monolithic perovskite-silicon tandem solar cells

Philipp Tockhorn, Johannes Sutter, Alexandros Cruz, Philipp Wagner, Klaus Jäger, Danbi Yoo, Felix Lang, Max Grischek, Bor Li, Jinzhao Li, Oleksandra Shargaieva, Eva Unger, Amran Al-Ashouri, Eike Köhnen, Martin Stolterfoht, Dieter Neher, Rutger Schlatmann, Bernd Rech, Bernd Stannowski, Steve Albrecht & Christiane Becker
Perovskite-silicon tandem solar cells allow to overcome the power conversion efficiency limit of conventional silicon solar cells. So far, various textured tandem devices have been presented aiming at improved optical performance, but optimal film growth on surface textured wafers remains challenging. Here we present perovskite-silicon tandem solar cells with periodic nanotextures that offer various advantages without compromising the material quality of solution-processed perovskite layers. We show the reduction of reflection losses in comparison to planar...
