Local Extinctions, Habitat Fragmentation, and Ecotones

  • Chapter
Landscape Boundaries

Part of the book series: Ecological Studies ((ECOLSTUD,volume 92))

Abstract

In this chapter, extinctions are explored in the context of mechanisms that operate during and after habitat fragmentation of, and with frequent references to, woodlands in farmland, where we have studied the process, although information from many other situations are also used. An ecotone that is relevant to a particular species must be a gradient from more survivable to less survivable conditions. A high density of these circumstances should be conducive to observing the processes of local extinction. Fragmentation creates ecotones, expands them, and moves them. Therefore, from the information that we have about fragmentation effects, it may be possible to learn about the effects of changing ecotones on species extinctions.
