university. Much new material had to be purchased; teaching started with new
lectures, seminars, practical lab and field courses, and excursions.
Most of the first studies in Bielefeld had an autecological basis and focused on the
effect of plants on distinct stress factors such as salt or heavy metals. Synecology,
geobotany and vegetation surveys were later included in several research projects.
During the following years in Bielefeld, many projects and studies were undertaken
in various countries abroad. Many candidates asked for a thesis, but we could not take
all. We were able to publish some of the results in Bielefelder Ökologische Beiträge
(BÖB), starting with volume 1 in 1985. After I became a pensioner in 2003, regular
editions stopped with volume 20 in 2004, but volume 21 was published in 2017.
