Firstof allI wouldliketo thankmyadvisorProf.Dr. HelmutSchuhmacher for theofferto
preparemythesisinhisdepartment at theUniversityof Duisburg-Essen. I’mespecially
gratefulto PDDr. D.Heringfor his exceptionaland alwaysconstructive guidancethrough
thelastyears. Thisincludes theopportunityto work in several international and national
research projects. Thankyou verymuchDaniel!
Numerous helping hands have contributed to this thesis by assistance during the field and
lab work. Special thanks to Marta Wenikajtys and Jörg Tenholtern for company and help
during the long-term sample trips throughout the Central European lowland and the lab
processing of many samples. I’m grateful to Dr. Armin Lorenz and Peter Rolauffs for their
contribution to the identification of the benthic invertebrates and together with Dr. Jochem
Kail for numerous stimulating discussions. Thanks also to Dr. Jochem Kail and Tanja Pott-
oofreading. rgiesser for p
I would like to thank Dr. V. W. Framenau, Western Australian Museum, Perth, Australia,
for numerous valuablecomments on and linguistic revisionof Chapters3 and4.Thanks to
Dr. Barbara Bis, University of Lodz, Poland, for the cooperation and assistance during the
field trips in Poland. Thanks also to Barbara for managing my car being repaired! For their
cooperative readiness for help, I would like to thank the following members (and former
members) of the Department of Hydrobiology, University of Duisburg-Essen: Sandra
Kramm, Dr. Armin Lorenz, Carolin Meier, Dr. Steffen Pauls, Peter Rolauffs, Dr. Mario
Sommerhäuser, and Jörg Strackbein.
Special thanks are due to the AQEM and STAR partners, particularly to Dr. Piet F. M. Ver-
Uppsala,Leonard Sandin, SLUDr.donschot, Alterra Wageningen, The Netherlands, andr providing their unpublished, foSwedendata.
And finally,a special thank is due tomyparents Elisabeth and HugoFeld,and toTanja
Pottgiesser for their extensive support and their encouraging trust in my work.
This thesis was derived from the data of two research projects funded by the European Un-
and Sustainable Develop-, Framework Programme: Energy, Environmention through the 5thment; Key Action Water: ‘The development and testing of an integrated assessment system
for the ecological quality of streams and rivers throughout Europe using benthic macroin-
vertebrates’ (AQEM; Contract No.: EVK1-CT 1999-00027) and ‘Standardisation of River
Classifications’ (STAR; Contract No.: EVK1-CT 2001-00089). The research in Poland
(‚The definition of macroinvertebrate-based reference conditions’ DEMARECO; Aktenzei-
chen: H 150 5506 9999 10605) was funded by the German Research Foundation
(‘Stifterverband für die Deutsche Wissenschaft’). The analysis of the German monitoring
data (Chapter 2) was partly supported by the Länderarbeitsgemeinschaft Wasser (LAWA;
Project No.: O 3.02). I’m grateful to all agencies who made their data available for this
. study
