Description: Das Projekt "Oribatid1-Milben-Ansammlungen in Kontaktbereichen zwischen Torfmooren und Wiesen: eine landschaftsorientierte Sichtweise" wird vom Umweltbundesamt gefördert und von Universite de Neuchatel, Faculte des Sciences, Institut de Zoologie durchgeführt. Species assembly rules are of both abiotic and biotic nature. Factors acting on local assemblage structures take their origin at various spatial and temporal scales. Previous results suggest that present day structures are related to past events (eg disturbances of human origin), and that local mite species assemblages show traces of interaction with the neighbouring as well as more remote species pools. Deeper understanding of the processes of soil mite assemblage building thus needs a broad, landscape approach, original in soil biology. We hypothesize a set of assembly rules acting at different scales: biogeographic situation, passive migration (eg water and wind-borne transportation), active migration, vegetation-linkes assemblage structuration. Experiments are conduced on the various migration types, in the lab (mite walking) and the field (soil scraping to provide free surfaces), and a sampling program seeks evidences of migration (eg by water filtering) and interpretable assemblage patterns.
