摘要: Abstract This research was carried out on the montane belt of a south-exposed watershed in Intermediary Alps which have been hit by agriculture abandonment. The aim study to relationships between vegetation, landscape mosaic, and two kinds animals using this space at different scales: roe deer ( Capreolus capreolus ) earthworms (lumbricids). Landscape dynamics (post-cultural recolonisation) structure approached means Arc/Info geographical information system (GIS). Several methods used one hand distribution, and, other, earthworm abundance diversity are developed. Of these, particular, GIS processing is sample according vegetation dynamics, distribution related heterogeneity. Earthworms more abundant diversified key steps dynamics. These lumbricids can be considered as functional indicators these Results also demonstrate that both type heterogeneity direct influence use deer. They show themselves structural landscape.
