Abstract
In this paper, the effect of slash and burn of a primary forest on the epigeic fauna are studied as well as its behaviour of colonization in Amazonian agriculture zones and distribution in its original habitats. It is supposed that, natural inundation areas and forests of a region represent the original
habitats of an agrarian fauna.
Strategies of colonization of the Carabidae were compared to those of Staphylinidae, Elateridae, Gelastocoridae, Isopoda, Diplopoda and Aves.
Inundation areas without forest (Litoraea) are found to be the most important faunal sources for the agrarian areas, with most of the flying arthropod species and birds originating from there. Numerous species of the non-flying macroarthropods originate from the forest.
Litoraea and anthropogenic cultivation areas as succesional ecosystems are more similar in
structure, dynamics and microclimate when compared to the primary forest. In anthropogenic ecosystems, the principal cause of reduced species numbers is the lack of structrual diversity and the microclimate. This results in a reduction of the biocenotic connex. [in German]
