Moss Biocrusts Regulate Heavy Metal Speciation and Mobility in Coal Mine Soils

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT On a global scale, coal mining activities often lead to heavy metal(loid) contamination in soils of mine dump sites, posing serious ecological risks. As ecosystem “engineers,” biological soil crusts (biocrusts)—especially moss crust—have shown great potential in remediating heavy metal‐polluted soils, but their roles remain underexplored.

Water Table Decline Shifts Microbial Necromass From Particulate to Mineral‐Associated Pools in Peatlands

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Microbial necromass carbon (MNC) is a major and stable component of soil organic carbon, yet its fraction‐specific accumulation and stabilization mechanisms remain unclear, particularly in peatlands experiencing hydrological change. We investigated MNC distribution along three independent transects spanning a natural gradient of five ...

Do Forest Fires and Land Degradation Undermine Environmental Sustainability? Evidence From China

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forest fires (FFs), land degradation (LD), and ineffective land use reduce carbon sinks, disrupt ecosystems, and increase greenhouse gas (GHG) emissions, creating challenges for environmental sustainability (ES). Addressing these challenges through targeted green investments (GIs) and effective land reforms (LRs) aligns with sustainable ...

Native Perennial Vegetation Buffer Strips Improve Structural Indicators of Riparian Protection in Mediterranean Agroecosystems

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Riparian zones in Mediterranean agroecosystems are highly vulnerable to degradation because cultivation often reaches stream edges and annual vegetation senesces during the late‐summer dry period, leaving soils exposed when the first erosive autumn rains occur.

Coupling of Physical Protection and Molecular Composition Drives Carbon Sequestration Divergence in Soils Planted With Different Tea Varieties

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Tea plantations represent significant carbon (C) sinks in agricultural landscapes, yet how variety‐specific organic inputs are associated with the molecular composition and stability of soil organic carbon (SOC) within aggregate hierarchies remains unclear.

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Higher NO3−‐N Levels Under Mulberry (Morus alba L.) Planting Enhanced CAZyme Abundance, Increasing Soil Carbon Stability

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Afforestation is widely advocated for boosting carbon (C) sequestration. However, the stability of soil C pools in economically and culturally significant mulberry plantations remains poorly understood. The soil organic C (SOC) contents in different aggregates and the oxidizable OC fractions were measured.

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

open access: yesLimnology 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.
