This is an excerpt from the content

The structure and functioning of forest ecosystems is currently considered to be threatened by a variety of anthropogenic environment changes, such as global warming and air pollution (Vitousek et al. 1997; Cramer et al. 2001). Since the Asian region contains both developed and developing nations, the way in which the forest ecosystems in the region have responded to the variety of environmental changes associated with population growth and/or economic development is being increasingly examined.

Soil nitrogen dynamics in forest ecosystems (e.g., nutrient uptake, litterfall, microbial decomposition and mineralization, atmospheric deposition or leaching) are central to understanding ecosystem functioning and processes, such as primary production, nutrient cycling, and changes in water quality at regional and global scales. Although studies have been conducted on the soil nitrogen dynamics of global and regional forest ecosystems for several decades, clarifying the nature of unique regiona
