Functional traits indicate a continuum of tree drought strategies across a soil water availability gradient in a tropical dry forest
Tropical dry forest Soil moisture content Functional guilds Drought avoidance Drought resistance Drought tolerance
2024/1/12
This study evaluates drought survival mechanisms of tropical dry forest (TDF) trees based on their functional traits (FTs). We addressed the following questions: (i) What are the dominant functional g...
Variations in Soil Properties and CO2 Emissions of a Temperate Forest Gully Soil along a Topographical Gradient
CO2 emission respiration C sequestration forest gully forest soil enzymatic activity
2024/1/11
Although forest soils play an important role in the carbon cycle, the influence of topography has received little attention. Since the topographical gradient may affect CO2 emissions and C sequestrati...
