Biogeochemical Cycling in Terrestrial Ecosystems - Individual Components, Interactions and Considerations Under Global Change

Terrestrial ecosystem biogeochemistry integrates biology, geology, and chemistry to provide a system-wide understanding of the controls on and interactions among ecosystems. Biological entities are composed of chemicals that are derived from both biotic and abiotic aspects of nature, and the activity of biota is thus intrinsically linked to the cycling of chemical elements. The balance of ecosystem biogeochemistry is largely dictated by interactions among carbon (C), nitrogen (N), and phosphorous (P). Here we discuss the individual aspects of C, N, and P cycling within terrestrial ecosystems, examine the response of these cycles to aspects of global change, and consider interactions among biogeochemical components of terrestrial ecosystems.

Keywords: Carbon; Nitrogen; Phosphorous; Global change; Coupling of biogeochemical cycles.
