Journal of Plant Nutrition and Soil Science, Volume 188, Issue 2, Page 299-311, April 2025.ABSTRACT Background During the last decades, gamma spectrometry data have increasingly been used in soil science, for example, for mapping. However, the full data potential could not be exploited due to certain constraints, among which the insufficient representation of attenuating materials (in particular, water) in correction algorithms is the most ...

International Journal of Osteoarchaeology, Volume 35, Issue 2, March/April 2025.ABSTRACT Pellagra is a disease caused by a nutritional deficiency, with fatal outcome due to multiple‐organ failure, that affected European rural areas until the early decades of the 20th century, especially Veneto region (Italy). At the skeletal level, previous studies pointed out that pathological signs left by the disease are generic and typical of ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.Abstract The neodymium isotope signatures (εNd) of the authigenic fraction have been extensively used to reconstruct past seawater εNd and hydrological circulation. Among the various methods, sequential extraction of hydrogenic ferromanganese oxyhydroxides from bulk sediments represents a rapid and straightforward approach that may potentially induce ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 4, April 2025.Abstract The Rapitan Group (Northwest Territories, Canada) includes banded iron formation (BIF), an unusual sediment type that is associated with late Neoproterozoic glaciations, in this case, the early Cryogenian Sturtian glaciation. New non‐traditional stable isotope data from jasper and hematite iron formation (IF) from the Cranswick River area ...

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 4, April 2025.Abstract Dissolved and suspended sediment samples were collected from the 121 km‐long proglacial Matanuska River and five associated tributaries in Southcentral Alaska (USA), in July 2019. Li elemental and isotopic (δ7Li) composition of dissolved load from proglacial river water samples and XRD analyses of the accompanying suspended sediments were ...

Paleoceanography and Paleoclimatology, Volume 40, Issue 4, April 2025.Abstract Throughout the Phanerozoic, the oceans repeatedly became oxygen depleted and deposited marine sediments called black shales. The mechanisms responsible for the compositional variability of black shales deposited at different times and places, however, are not yet fully understood.

Functional Ecology, Volume 39, Issue 4, Page 985-1000, April 2025.Read the free Plain Language Summary for this article on the Journal blog. Abstract Nodulating leguminous and actinorhizal N2‐fixation pioneer plants are well‐known drivers of primary succession as they may facilitate soil development and the growth of neighbouring non‐nodulating plant species as a result of their N2‐fixing capacity.
