The prospective of our work is to figure out the electronic and structural properties of the material and to optimize proper catalysts or design new ones for best catalytic activity. Beside the spectro-microscopic investigations the catalysts are tested under Sabatier reaction conditions in terms of activity, stability and sensitivity against poisoning.

In Germany, they include antenatal classes, breastfeeding classes and pregnancy-specific yoga or gymnastics courses. Studies suggest that various types of non-medical ANC carry benefits for both the women and their babies. Little is known about the uptake of non-medical ANC among different socioeconomic population subgroups, but one may expect lower utilization among socio-economically disadvantaged women. We analyzed factors contributing to the utilization of non-medical ANC in general and antenatal classes in particular. Methods: Baseline data of the Bielefeld BaBi birth cohort (2013-2016) and the Berlin perinatal study (2011-2012) were analyzed. Comparing the two cohorts allowed to increase the socio-economic and migration background variance of the study population and to capture the effect of the local context on uptake of services. Multivariate logistic regression analyses were performed to study associations between the uptake of non-medical ANC and socio-economic and migration status.ResultsIn Berlin and Bielefeld, being a first generation migrant and having lower levels of education were associated with lower non-medical ANC uptake. In Berlin, being a 2nd generation woman or having a low income was also associated with lower uptake. Conclusions for Practice: Our study suggests that non-medical ANC remains in some part the prerogative of non-migrant, well-educated and economically privileged women. Since differences in non-medical ANC have the potential to create inequalities in terms of birth outcomes and maternal health during pregnancy and post-partum, more efforts are needed to promote the use of non-medical ANC by all population groups.}, language = {en} } @misc{BendixAguireBecketal., author = {Bendix, J{\"o}rg and Aguire, Nicolay and Beck, Erwin and Br{\"a}uning, Achim and Brandl, Roland and Breuer, Lutz and B{\"o}hning‑Gaese, Katrin and Paula, Mateus Dantas de and Hickler, Thomas and Homeier, J{\"u}rgen and Inclan, Diego and Leuschner, Christoph and Neuschulz, Eike L. and Schleuning, Matthias and Suarez, Juan P. and Trachte, Katja and Wilcke, Wolfgang and Windhorst, David and Farwig, Nina}, title = {A research framework for projecting ecosystem change in highly diverse tropical mountain ecosystems}, series = {Oecologia}, volume = {195}, journal = {Oecologia}, number = {3}, issn = {0029-8549}, doi = {10.1007/s00442-021-04852-8}, pages = {589 -- 600}, abstract = {Tropical mountain ecosystems are threatened by climate and land-use changes. Their diversity and complexity make projections how they respond to environmental changes challenging. A suitable way are trait-based approaches, by distinguishing between response traits that determine the resistance of species to environmental changes and effect traits that are relevant for species' interactions, biotic processes, and ecosystem functions. The combination of those approaches with land surface models (LSM) linking the functional community composition to ecosystem functions provides new ways to project the response of ecosystems to environmental changes. With the interdisciplinary project RESPECT, we propose a research framework that uses a trait-based response-effect-framework (REF) to quantify relationships between abiotic conditions, the diversity of functional traits in communities, and associated biotic processes, informing a biodiversity-LSM. We apply the framework to a megadiverse tropical mountain forest. We use a plot design along an elevation and a land-use gradient to collect data on abiotic drivers, functional traits, and biotic processes. We integrate these data to build the biodiversity-LSM and illustrate how to test the model. REF results show that aboveground biomass production is not directly related to changing climatic conditions, but indirectly through associated changes in functional traits. Herbivory is directly related to changing abiotic conditions. The biodiversity-LSM informed by local functional trait and soil data improved the simulation of biomass production substantially. We conclude that local data, also derived from previous projects (platform Ecuador), are key elements of the research framework. We specify essential datasets to apply this framework to other mountain ecosystems.}, language = {en} } @incollection{NaumannRudolph, author = {Naumann, Matthias and Rudolph, David}, title = {L{\"a}ndliche Utopien als infrastrukturelle Utopien : Progressive Alternativen zu infrastruktureller Peripherisierung und infrastrukturellem Populismus.}, series = {L{\"a}ndliche Utopien : Herausforderungen und Alternativen regionaler Entwicklungen.}, booktitle = {L{\"a}ndliche Utopien : Herausforderungen und Alternativen regionaler Entwicklungen.}, publisher = {Transcript Verlag}, address = {Bielefeld}, isbn = {978-3-8394-7233-0}, doi = {10.1515/9783839472330}, pages = {115 -- 126}, language = {de} } @misc{EdlingerGarlandBanerjeeetal., author = {Edlinger, Anna and Garland, Gina and Banerjee, Samiran and Degrune, Florine and Garc{\´i}a-Palacios, Pablo and Herzog, Chantal and Pescador, David S{\´a}nchez and Romdhane, Sana and Ryo, Masahiro and Sagha{\"i}, Aur{\´e}lien and Hallin, Sara and Maestre, Fernando T. and Philippot, Laurent and Rillig, Matthias C. and Heijden, Marcel G.

However, we lack a comprehensive understanding of how soil organic carbon (SOC) and aggregate stability respond to agricultural management across wide environmental gradients. Here, we assessed the impact of climatic factors, soil properties and agricultural management (including land use, crop cover, crop diversity, organic fertilization, and management intensity) on SOC and the mean weight diameter of soil aggregates, commonly used as an indicator for soil aggregate stability, across a 3000 km European gradient. Soil aggregate stability (-56\%) and SOC stocks (-35\%) in the topsoil (20 cm) were lower in croplands compared with neighboring grassland sites (uncropped sites with perennial vegetation and little or no external inputs). Land use and aridity were strong drivers of soil aggregation explaining 33\% and 20\% of the variation, respectively. SOC stocks were best explained by calcium content (20\% of explained variation) followed by aridity (15\%) and mean annual temperature (10\%). We also found a threshold-like pattern for SOC stocks and aggregate stability in response to aridity, with lower values at sites with higher aridity. The impact of crop management on aggregate stability and SOC stocks appeared to be regulated by these thresholds, with more pronounced positive effects of crop diversity and more severe negative effects of crop management intensity in nondryland compared with dryland regions. We link the higher sensitivity of SOC stocks and aggregate stability in nondryland regions to a higher climatic potential for aggregate-mediated SOC stabilization.

While topographical and climatic factors are often considered to drive microbial communities on a continental scale, higher trophic levels like heterotrophic protists also rely on their food sources. In this context, bacterivores have received more attention than fungivores. Our study explored the connection between the community composition of protists (specifically Rhizaria and Cercozoa) and fungi across 156 cereal fields in Europe, spanning a latitudinal gradient of 3000 km. We employed a machine-learning approach to measure the significance of fungal communities in comparison to bacterial communities, soil abiotic factors, and climate as determinants of the Cercozoa community composition. Our findings indicate that climatic variables and fungal communities are the primary drivers of cercozoan communities, accounting for 70\% of their community composition. Structural equation modelling (SEM) unveiled indirect climatic effects on the cercozoan communities through a change in the composition of the fungal communities. Our data also imply that fungivory might be more prevalent among protists than generally believed.

This fundamental question has been debated among leading scholars for centuries, and more recently, it has been tested in experimental studies yielding a body of rather inconclusive empirical evidence. A potential source of ambivalent empirical results on the same hypothesis is design heterogeneity—variation in true effect sizes across various reasonable experimental research protocols. To provide further evidence on whether competition affects moral behavior and to examine whether the generalizability of a single experimental study is jeopardized by design heterogeneity, we invited independent research teams to contribute experimental designs to a crowd-sourced project. In a large-scale online data collection, 18,123 experimental participants were randomly allocated to 45 randomly selected experimental designs out of 95 submitted designs. We find a small adverse effect of competition on moral behavior in a meta-analysis of the pooled data. The crowd-sourced design of our study allows for a clean identification and estimation of the variation in effect sizes above and beyond what could be expected due to sampling variance. We find substantial design heterogeneity—estimated to be about 1.6 times as large as the average standard error of effect size estimates of the 45 research designs—indicating that the informativeness and generalizability of results based on a single experimental design are limited.
