Spatio-temporal patterns of temperature in mountain environments are complex due to both regional synoptic-scale and landscape-scale physiographic controls in these systems. Understanding the nature and magnitude of these physiographic effects has practical and theoretical implications for the development of temperature datasets used in ecosystem assessment and climate change impact studies in ...

A conceptual scheme for the interpretation of physiographic regions, developed in an earlier effort, is formalized and programmed in Smart Elements resulting into a prototype knowledge-based expert system for physiographic reasoning, named TAX-4 (Terrain Analysis eXpert 4). An object-oriented model involving class-subclass hierarchies was formalized for the representation of factual and structu...

Wyant, J.G., Alig, R.J. and Bechtold, W.A., 1991. Physiographic position, disturbance and species composition in North Carolina coastal plain forests. For. Ecol. Manage., 41: 1-19. Relations among physiographic heterogeneity, disturbance and temporal change in forest composition were analyzed on 765 forest stands in the southern coastal plain of North Carolina. Physiographic position strongly r...

Using historical General Land Office record as a reference, this study employed a landscape-scale disturbance and succession model to estimate the future cumulative effects of six alternative management plans on the tree species composition for various physiographic settings for the Mark Twain National Forest in Missouri. The results indicate that over a 200-year horizon, the relative abundance...
