Mycorrhiza in liverworts and hornworts
In a joint project with Ingrid Kottke and Franz Oberwinkler (Universität Tübingen), the morphology and ultrastructure of the mutualists are studied and the symbiontic fungi are identified by molecular analysis. The studies on function and evolutionary importance of the mycorrhiza are carried out in Central Europe and in the tropics of South America as a part of the project 'functionality in a tropical mountain rainforest: diversity, dynamic processes and utilization potentials under ecosystem perspectives'. The studies in South America are supported by the DFG (FOR 402) until January 2007.

The importance of mycorrhiza in the evolution of land ecosystems
In cooperation with Ingrid Kottke (Tübingen), the fungi symbiosis of the Pallaviciniaceae, a basal group of liverworts, is investigated.

Bioindication with help of bryophytes. The effects of the climatic change and pollutants on the bryophyte flora
Biomonitoring on selected sample areas in beech forests. In cooperation with Michael Sauer and Jürgen Waizel (School of Forestry Rottenburg). Supported by the 'Landesanstalt für Umweltschutz' (State Institution for the Protection of the Environment). Long-term study since 1989, the next re-examination will start in 2006.

Nature as Model - Impulses for new structures of organizationin companies and administrations
In a cooperation with Klaus Götz (University of Koblenz-Landau, centre of Human Ressource Management), it is investigated, whether the organization principles of nature may serve as metaphors for the optimization of organization processes.

Tasks within the scope of the project:
Formulation of texts of every species including morphology, ecology, distribution, population, threat and protection evaluating literature and all accessible documents.
Critical revision of all available specimens.
Field works for the completion of the floristic mapping.
Studies of ecology and phytosociology, detection of the reasons for threats.
Bioidnication: creation of a checklist of all epiphytes ordered according to their sensibility. Bryophytes as indicators of climatic changes.
Volume 1 contains a general part and the Andreaeales and the acrocarp mosses.
Volume 2 contains the acrocarp mosses part II and the pleurocarp mosses.
Volume 3 is due to be published in 2004 and will deal with the bog mosses, liverworts and hornworts.
This project is supported by the regional Landesministerium für Ernährung und Ländlichen Raum (=State Ministry of Nutrition and Countryside) of Baden-Württemberg. It is due to be finshed in 2004.
