Non-destructive methodology for determining carbon content in large or semi-infinite (soil) samples is discussed. This methodology is based on deconvoluting the sample's gamma spectra (received by tagged neutron method) on the sample component's spectra by accounting for neutron and gamma radiation attenuations. This algorithm was tested with both Monte-Carlo simulations and experimental gamma spectra. Good agreement was found between defined and actual sample component content. Application of this method for soil carbon determinations in agricultural fields is discussed.

Specialized plant metabolism, particularly phenolic compound production, contributes significantly to the functioning and resilience of mountain ecosystems. Livestock grazing can influence phenolic production, with its effects varying depending on microclimatic factors and soil conditions. Despite the ecological significance of this process, the impact of livestock grazing on phenolic production in alpine plants remains insufficiently explored.

During the Late Bronze Age (ca. 11th-8th century BCE), far-reaching and extensive trade and exchange networks linked communities across Europe. The area around Seddin in north-western Brandenburg, Germany, has long been considered as at the core of one such networks.

A novel bacterial strain, SM-13 was isolated from the rhizospheric soil of Epipremnum aureum (Jade Pothos) sampled in Suwon, Republic of Korea. The isolate was Gram-stain-negative, aerobic, motile, rod-shaped, cream-coloured, oxidase- and catalase-positive. Strain SM-13 grew at the range of 15-37 °C (optimum, 25 °C), at pH 6.

The Earth's grasslands have experienced extensive alterations to their grazing regimes over the course of human history. We asked how native grassland herbivores (bison, prairie dogs, and grasshoppers) and a non-native herbivore that has become dominant (cattle) affect seasonal patterns of plant and soil elemental chemistry and aboveground plant biomass in a shortgrass prairie in the North American Northern Great Plains. To quantify herbivore effects, we sampled plants and soils across 4 months of the growing season in 15 grassland sites comprising five herbivore regimes with varying densities of bison, cattle, prairie dogs, and grasshoppers.
