Description: Das Projekt "Integrierte Studie der globalen biologischen Vielfalt von Wiesen mittels Mikroflora und Pedofauna" wird vom Umweltbundesamt gefördert und von Orlab durchgeführt. Leading Questions: a) Contribution to soil biology b) Global, multi-scale approach to biodiversity in an edaphic environment c) Maximum integration of research realized on two different but interacting functional levels d) New application of analytical methods e) This research is oriented in the direction of establishing a biodiversity-derived diagnostic for fertility in agricultural environments. f) Interdisciplinarity. Abstract: In the soil, the diversity of the components of the decomposition chain gives an indirect measure of soil-fertility. But the organisms involved work at different scales. Thus, studying their interactions requires a simultaneous evaluation of the faunas tic diversity and the microbial spectrum. Here we evaluate diversity of macro arthropods, micro arthropods and micro flora (fungi and bacteria) on the same samples. The measures are compared with each other, and put in relation with the biochemical traces of biological activity in the soil, which give another measure of soil fertility. The measured traces are selected enzymes, ATP content, and CO2 release. Biodiversity is thus studied for itself and compared over several scales (with organism sizes ranging from the cm to the um), but applications are also expected, in the form of biodiagnostic techniques of soil fertility, pollution monitoring, or risk assessment related to the application of sanitation techniques on heavily polluted soils.
