THE AUTHOR'S CONTRIBUTION

I and II. German Jurgens planned and conducted the experiments, analyzed and interpreted the results as well as wrote the paper, under supervision of project leader Aimo Saano. Kristina Lindström acted as an expert in phylogenetic analysis for paper I.

III. The work in this study was done in cooperation with Cristina Abreu (Portugal) while she was on Socrates scholarship in University of Helsinki during spring 1998. Cristina Abreu conducted the experiment and wrote the paper. German Jurgens planned and instructed the research, conducted the phylogenetic analysis and assisted in writing the paper. Aimo Saano, Paolo de Marco and Adriano Bordalo supervised the work.

IV. German Jurgens planned and conducted the experiments, analyzed and interpreted  the results and wrote the paper. Frank-Oliver Glöckner made the FISH picture and acted as FISH experiments adviser and ARB phylogenetic software expert. Markit Likolammi prepared bacteria biomass and bacteria production measurements and Leone Montonen performed PCR analysis with methyl-coenzyme M reductase primers. Rudolf Amann, Aimo Saano and project leader Uwe Münster supervised the work and assisted in writing.
