Edge effects in geomorphology

Auteur :
PHILLIPS, J.D.

Description :
Three general types of edges effects are identified and illustrated with examples from the North Carolina coastal plain. First, ecological edge effects may have a geomorphic expression owing to the biogeomorphic impacts of plants and animals. This is illustrated by ant bioturbation along a forest-grass boundary. Second, edge effects may be associated with unique geomorphic controls along boundaries : ferricretes. Third, geomorphic edge effects may be associated with force-resistance differences along landscape boundaries : field-edge eolian ridges. It is important to recognize that landforms and processes along edges may not be representative of those in the adjacent landscapes.
