Effects of Spruce Plantations On Carabid Beetles in Southern Belgium

摘要: (1) During 1989 and 1990, carabid beetles were collected monthly in 11 spruce plantations of increasing age. The total sample includes 3997 individuals belonging to 50 species. (2) Most colonizing species either generalist species, well-fitted colonization, or forest (3) Age the plantation affects both composition richness communities. These variations are correlated with changes structural vegetational characteristics plantations. (4) A strong heterogeneity between communities occurring young was detected. This seems depend on local ecological conditions. (5) Comparisons those other regional habitats show that from pool take advantage availability a new habitat build populations. (6) On scale, forestry acts as patch dynamics system disturbance. importance exchange pieces mosaic is outlined.
