Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

Advanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.

The synergistic effects of a leaf mixture on decomposition change with a period of terrestrial exposure prior to immersion in a stream

Ecology and Evolution
The effect of mixing litter on decomposition has received considerable attention in terrestrial and aquatic (but rarely in both) ecosystems, with a striking lack of consensus in the obtained results.

Effects of biochar application methods on ammonia (NH₃) volatilization from used broiler litter

Journal of Applied Poultry Research
Summary: Elevated ammonia (NH₃) emissions from litter are a concern in modern broiler production and can negatively influence performance and welfare. While commercially available litter amendments are commonly used to mitigate ammonia emissions, their ...

A diagnostic study of temperature controls on global terrestrial carbon exchange [PDF]

, 2001
The observed interannual variability of atmospheric CO2 reflects short-term variability in sources and sinks of CO2 . Analyses using 13CO2 and O2 suggest that much of the observed interannual variability is due to changes in terrestrial CO2 exchange ...

Impact of short-term storage on the quantity of extended-spectrum beta-lactamase–producing Escherichia coli in broiler litter under practical conditions [PDF]

, 2020
Applying broiler litter containing extended-spectrum beta-lactamase (ESBL)–producing Escherichia coli (E. coli) to arable land poses a potential risk for humans to get colonized by contact with contaminated soil or vegetables.

mGluR5 in ECCCK to BLA Circuit Modulates Depressive‐Like Phenotypes through CCK Signaling

Advanced Science, EarlyView.
Dysregulation of mGluR5 and CCK signaling contributes to major depressive disorder, yet circuit‐level mechanisms remain unclear. Here, the ECCCK→BLA pathway is identified as a critical regulator of affective behavior. mGluR5 modulates synaptic function and CCK signaling within this circuit, controlling stress susceptibility and depressive‐like states ...

Influence of soil macrofauna on soil organic carbon content

Environmental Protection and Natural Resources, 2018
Macrofauna plays a very important role in the functioning of the natural environment. It plays an important role in the decomposition of organic matter by mixing and crushing organic matter in soil.

Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice

Advanced Science, EarlyView.
This study investigates [14C]polystyrene nanoplastic ([14C]PS) translocation in late‐stage pregnant mice after intranasal (0.5 mg of [14C]PS on GD12, GD14, and GD16, n = 6) and intravenous administration (1.5 mg of [14C]PS on GD16, n = 6). 14C‐radiolabel allows quantitative tracking of unmodified polystyrene nanoplastics.
