Now, however, there is an appreciation that abiotic and biotic components move through heterogeneous landscapes and that the boundaries between these landscape units take on important control functions in such dynamic spatial systems. Also, landscape boundaries (ecotones) are imp

This review attempts to summarize general characteristics of boundaries and identify the research difficulties that must be addressed before fundamental characteristics can be iden
