Effects of Post-Thinning Precipitation on Soil Acid Phosphomonoesterase Activity in Larix principis-rupprechtii Mayr. Plantations
precipitation thinning acid phosphomonoesterase Larix principis-rupprechtii Mayr
2024/2/29
Soil phosphorus (P) is one of the essential macronutrients for plant growth. Phosphatase-mediated P mineralization in particular is critical for the biogeochemical cycling of P, and its activity refle...
MODELING PRECIPITATION DEPENDENT FOREST RESILIENCE IN INDIA
Resilience Total Annual Precipitation Logistic Regression Forest Climate Regime Change Proneness
2018/5/11
The impact of long term climate change that imparts stress on forest could be perceived by studying the regime shift of forest ecosystem. With the change of significant precipitation, forest may go th...
