Long‐Term Nitrogen Addition Weakens the Linkage Between Phosphorus Cycling Gene Abundance and Phosphatase Activity Through Soil Acidification in a Larix gmelinii Plantation

Land Degradation &Development, EarlyView.
ABSTRACT Anthropogenic nitrogen (N) enrichment propels global forest ecosystems toward phosphorus (P) limitation, theoretically triggering the upregulation of microbial P‐acquisition capacity to maintain stoichiometric balance. However, the extent to which N addition regulates this adaptive capacity remains uncertain.

Microbial diversity, autotrophic- and heterotrophic processes in Mn-rich marine sediments

Frontiers in Marine Science
Marine microbial ecology aims to link microbial communities to the geochemical processes they drive. Molecular techniques have provided a view of the huge complexity of microbial communities and their metabolic potential, however, the information these ...

Soil Humic Substances and Root Exudates: Key Factors Modulating Cadmium Mobility in Paddy Soils Under Organic Fertilization

Land Degradation &Development, EarlyView.
ABSTRACT Cadmium (Cd) contamination in paddy fields poses a high potential risk of environmental exposure. Organic fertilizer application can promote the efflux of rice root exudates, increase soil organic matter, and induce changes in Cd activity in rice fields.

Ecological Restoration of Degraded Mining Soils Through Key‐Layer Construction Using Industrial By‐Products: A Comprehensive Analysis of Soil Physics, Microbiology, and Maize Yield

Land Degradation &Development, EarlyView.
ABSTRACT Coal mining severely degrades soil profiles and ecosystem functions, highlighting the need for effective reclamation. Reconstructing soil profiles with industrial solid wastes offers a promising waste‐to‐resource approach, but the ecological effects of different engineered key‐layer materials remain unclear.

Beyond Chemical Compliance: A Critical Review Toward Microbiome‐Informed Ecological Exit Criteria for Bioremediated Soils

Land Degradation &Development, EarlyView.
ABSTRACT Chemical compliance remains the usual endpoint for closing contaminated‐soil remediation projects, although it does not establish recovery of soil function or the durability of the post‐treatment state. This critical review examines when microbiological evidence can contribute to ecological closure decisions.

Effects of preservatives and poisons on the elemental and isotopic composition of freshwater particulate organic matter

Limnology and Oceanography: Methods, EarlyView.
Abstract Sediment traps, often used in tandem with preservatives or poisons, are widely used for the collection of particulate organic matter (POM), providing insight into the source to sink mechanisms that shape major biogeochemical cycles and sedimentary carbon sequestration.
