Can DNA from wet, temperate soils be used for palaeoecological reconstruction?

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary ancient DNA in well‐dated contexts (sedaDNA) has great potential as a palaeoecological proxy. A few studies have attempted palaeoecological reconstructions using sedaDNA from soil; these studies have been mainly restricted to cold and/or dry soils.

Simulated Root Exudation Gradient Reveals Dosage‐Dependent Carbon Sequestration in Desertification Ecosystems

Land Degradation &Development, EarlyView.
ABSTRACT Root exudates serve as a key driver for the restoration of soil organic carbon (SOC), particularly in aeolian desertification ecosystems where aboveground litter retention is limited. While Salix cupularis is widely planted as an effective pioneer shrub for ecological rehabilitation on the Qinghai‐Tibet Plateau, how the quantity of its root ...

Macrophyte litter mixtures mediate decomposition processes in coastal sediments

Communications Earth & Environment
Understanding litter decomposition processes in coastal macrophyte habitats is critically important for predicting ecosystem functioning. However, decomposition processes of litter mixtures in coastal habitats remain largely unexplored.

Carbon‐Fixing Bacterial Network Complexity Mediates Soil Multifunctionality in a Panax notoginseng‐Pinus armandii Agroforestry System

Land Degradation &Development, EarlyView.
ABSTRACT Autotrophic carbon‐fixing bacteria (CFB) are central contributors to soil carbon sequestration and biogeochemical carbon cycling in agroforestry ecosystems and can act as reliable biological indicators for evaluating agroforestry ecosystem sustainability.

Litter-type-specific succession of microeukaryotic communities and their associations with litter decomposition

Geoderma
Litter decomposition regulates nutrient cycling and carbon turnover, with fungi arguably being the main drivers. While protists are interacting with fungi, their role, as well as the interaction between both groups of microeukaryotes in litter ...

Lateral Carbon Transport Induced by Watershed Erosion: Driving Effects of Land Use, Rainfall, and Landscape Controls

Land Degradation &Development, EarlyView.
ABSTRACT Lateral carbon transport induced by soil erosion is a key component of the global carbon cycle. Over the past 50 years, ecological restoration projects in the Loess Plateau of China have increased vegetation coverage. However, the effects of land use, precipitation variability, and landscape factors on lateral carbon transport remain unclear ...

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

Land 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.

Temporal dynamics of climate sensitivity of litter decomposition in a semi-arid grassland

Geoderma
Climate warming, precipitation changes, and reactive nitrogen (N) input are important environmental changes that can critically affect litter decomposition and soil carbon (C) dynamics.

Nitrogen enrichment impacts on boreal litter decomposition are driven by changes in soil microbiota rather than litter quality

Scientific Reports, 2017
In nitrogen (N) limited boreal forests, N enrichment can impact litter decomposition by affecting litter quality and by changing the soil environment where litter decomposes.

Rainfall frequency, not quantity, controls isopod effect on litter decomposition [PDF]

, 2019
Increasing climate variability is one of the dominant components of climate change, resulting particularly in altered rainfall patterns. Yet, the consequences of rainfall variability on biogeochemical processes that contribute to greenhouse gas emissions
