Extract

Insect species etc. comprise about 80% of the specific and subspecific taxa of the animal kingdom, and their conservation is an important, integral, and contemporary, aspect of the conservation of biological diversity. The species richness of this vast group makes detailed studies of all components insurmountable relative to the urgency for diversity conservation solutions. Landscape ecology offers a way of conceptualizing the situation, and is a tool for management. This approach is explored in the present paper, using the extensive data available on decticine bush crickets in the Montpellier region of southern France. Corridors, patches, and matrices, are considered, with special reference to the bush crickets' distributions at the boundaries of these elements.

As well as movement across the boundaries and resident interpenetration of these elements by those insects the ecotones are also important ecological entities in their own right. Additionally, vertical, as well as horizontal, aspects of landscape elements are important for these small animals with small home-ranges.
