Abstract
  • The specific objectives of the program are: (1) To understand the relative behavior of terrestrial and aquatic ecosystems in various environments in the biome. (2) To develop conceptual and computer simulation models that describe nutrient, carbon, and waterflows on a short-term basis (fewer than ten years) and which integrate research results and increase our understanding of coniferous forests and associated aquatic ecosystems. These models are being developed at the process, forest stand or water column, and watershed levels. (3) To develop conceptual and computer simulation models that describe the long-term behavior of coniferous forest ecosystems involving succession and erosion. (4) To understand the linkages between terrestrial and aquatic ecosystems. (5) To determine the effect of manipulations, such as clearcutting, fertilization, and defoliation on terrestrial and aquatic ecosystems.
