Spatiotemporal patterns and driving factors for vegetation growth status in the upper reaches of the Yellow River

open access: yesRiver, EarlyView.
This study developed the WEP‐CHC model, integrating vegetation growth dynamics into the hydrological WEP framework, to explore the spatiotemporal patterns and driving mechanisms of vegetation growth status (VGS) in the upper Yellow River. The results revealed significant spatiotemporal variability in VGS, with annual hydrothermal conditions and soil ...

Functional traits and habitat use: Investigating community assembly in a montane community (Carabidae: Nebria)

open access: yesEcosphere
The processes that influence community assembly, such as competition for resources and environmental filtering, are often scale dependent and vary across ecotones.

Impact of Geometry on Chemical Analysis Exemplified for Photoelectron Spectroscopy of Black Silicon

open access: yesSmall Methods, EarlyView.
This study describes how layer thicknesses of nano‐rough surfaces, here black silicon, can be determined by combining spectroscopic and topographical data. Angular integrated spectroscopic data (XPS) of nano‐rough surfaces are least‐square fitted to angular resolved data from an ultra‐flat surface, here Si wafer, after weighting the latter by the ...

Power‐to‐X Processes with Synthetic Iron Oxides

open access: yessteel research international, EarlyView.
Iron oxide redox cycling connects electrolytic hydrogen production and storage, enabling synthesis gas generation for synthetic hydrocarbons. Integrating H2/CO2 cycles offers carbon‐neutral energy storage and industrial applications, especially in commodity chemical industries. An aluminous‐rich binder stabilizes a sample over 20 H2/CO2 cycles, without

Taxonomy and dated molecular phylogeny of Allium oreophilum sensu lato (A. subg. Porphyroprason) uncover a surprising number of cryptic taxa

open access: yesTAXON, EarlyView.
Abstract Allium oreophilum, hitherto the representative of the monotypic A. subg. Porphyroprason from the second evolutionary lineage of Allium, is studied in detail. Over about 150 years, A. oreophilum was regarded as a somewhat polymorphous species with two synonyms, all described in the 19th century.
