Confocal μ-XANES as a tool to analyze Fe oxidation state in heterogeneous samples: the case of melt inclusions in olivine from the Hekla volcano [PDF]
European Journal of MineralogyHere we present a confocal Fe K-edge μ-XANES method (where XANES stands for X-ray absorption near-edge spectroscopy) for the analysis of Fe oxidation state in heterogeneous and one-side-polished samples.

Improving Vegetation Mapping from LiDAR Point Clouds Using a Transmissivity-Based Feature
Remote SensingUrban vegetation provides essential ecosystem services, including temperature regulation, air purification, noise reduction, and carbon storage. However, urban densification and climate-induced stresses increasingly threaten these ecosystems.

The German Soil Systematics and the Rationale Behind Its Revision
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background The German Soil Systematics is a pedogenetic classification based on the morphological expressions of pedogenic processes and has been developed over several stages since 1952. The system has successfully been in use for soil classification and soil survey for almost 70 years.

Interactions between main channels and tributary alluvial fans: channel adjustments and sediment-signal propagation [PDF]
Earth Surface Dynamics, 2020 Climate and tectonics impact water and sediment fluxes to fluvial systems. These boundary conditions set river form and can be recorded by fluvial deposits.

Oikos, EarlyView.Climatic conditions shape phenotypic evolution by driving adaptations that optimise organismal function. Invasive species provide valuable systems to study these processes, as they often encounter novel climatic conditions in their introduced ranges. The European rabbit Oryctolagus cuniculus, native to the Iberian Peninsula, has established populations

Sub-micrometer refractory carbonaceous particles in the polar stratosphere [PDF]
Atmospheric Chemistry and Physics, 2017 Eleven particle samples collected in the polar stratosphere during SOLVE (SAGE III Ozone loss and validation experiment) from January until March 2000 were characterized in detail by high-resolution transmission and scanning electron microscopy (TEM ...

Composition and Provenance of Victoria Group Sandstones in Southern North Victoria Land, Antarctica
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 3, September 2026.Three distinct source areas contributed to sandstones of the Victoria Group within the Transantarctic Basin in southern North Victoria Land. During the Permian, quartzose sandstones were derived from erosion of the local Ross Orogen, likely from an uplifted swell in the area of today's Ross Sea, the Ross High.

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds
The Anatomical Record, Volume 309, Issue 8, Page 2124-2150, August 2026.Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.
