Effects of Ferrostatin‐1 on Vocal Folds in Aging Rats

The Laryngoscope, EarlyView.
Age‐related vocal fold degeneration is associated with oxidative stress, and ferroptosis may contribute to structural changes in aging vocal folds. In this aged rat model, intracordal injection of the antioxidant ferrostatin‐1 attenuated ferroptosis‐related changes and was associated with modulation of collagen accumulation, hyaluronic acid ...

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.

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

Post‐Fire Soil Organic Carbon Dynamics: Decline and Recovery Over Two Decades

Land Degradation &Development, EarlyView.
ABSTRACT Wildfire can significantly alter soil organic carbon (SOC) dynamics in forest ecosystems, with complex temporal patterns following fire events. However, research on post‐fire SOC recovery remains limited, particularly in dry‐warm valley regions that are prone to frequent forest fires.

Improving Soil Health and Crop Yields Through Conservation Agriculture and Nutrient Management in Central India

Land Degradation &Development, EarlyView.
ABSTRACT Maintaining soil health and crop productivity in the semi‐arid Vertisols of central India poses a significant challenge under intensive agricultural practices. This 6‐year field study assessed the combined impact of different tillage methods, maize‐based crop rotations, and nitrogen management on soil's physical, chemical, and biological ...

Forest Conversion Reduces Soil Water Retention in Tropical Rainforest

Land Degradation &Development, EarlyView.
ABSTRACT Extensive primary forests are being converted to secondary forests and plantations owing to human activities in recent decades, which have substantial effects on soil hydrological processes. However, the potential impact of forest conversion on soil water retention remains poorly understood.
