OUTLINE OF THE THESIS the two different predators ranged from competition for the phototrophic prey to predation on the smaller predator (“intraguild predation”). Contrary to the theoretical expectations I found that the presence of the larger ciliate promoted the small dinoflagellate predator. Live observations revealed that the larger predator facilitated food uptake in the smaller predator by the pre-condition of prey cells. This commensalistic element in the interactive patterns between both predators is reported in Manuscript IV. Discussion Finally, a general discussion summarises the results obtained during the whole PhD research. The findings which are presented in the single chapters are discussed in a more general scientific context, thereby showing to what extent the research aims were achieved. A short outlook on the role of microzooplankton in a future global warming scenario and on future challenges completes this section. 16
OUTLINE OF THE THESIS List of manuscripts This thesis consists of four chapters. Each chapter represents one manuscript, which has either been published (Manuscript II), been submitted (Manuscript I, III) or is about to be submitted (Manuscript IV). Manuscript I (submitted to Helgoland Marine Research): Löder, M. G. J., Kraberg, A. C., Aberle, N., Peters, S. & Wiltshire, K. H.: Dinoflagellates and ciliates at Helgoland Roads, North Sea. The laboratory investigations were carried out by M. G. J. Löder. All co-authors contributed to planning and to the manuscript. Manuscript II (published in Marine Biodiversity Records): Löder, M. G. J., Aberle, N., Klaas, C., Kraberg, A. C. & Wiltshire, K. H., 2010: Conserving original in situ diversity in microzooplankton grazing set-ups. Marine Biodiversity Records, 3, e28. doi: 10.1017/S1755267210000254. http://journals.cambridge.org/action/displayJournal?jid=mbd. Experiments and analyses were carried out by M. G. J. Löder. All co-authors contributed to the manuscript. C. Klaas provided a special training on standard techniques and advice on results. Manuscript III (submitted to Marine Biology): Löder, M. G. J., Meunier, C., Wiltshire, K. H., Boersma, M. & Aberle, N.: The role of ciliates, heterotrophic dinoflagellates and copepods in structuring spring plankton communities at Helgoland Roads, North Sea. Planning of the experiments was carried out in consultation with all co-authors. Analyses of the samples and results were carried out by M. G. J. Löder and C. Meunier following the advice of the co-authors. All authors contributed to the manuscript. Manuscript IV (to be submitted): Löder, M. G. J., Boersma, M., Kraberg, A. C., Aberle, N. & Wiltshire, K. H.: They can promote their competitors - commensalism between microzooplankton predators. Experiments and analyses were carried out by M. G. J. Löder with advisory help of the other authors. Writing the manuscript was done in close cooperation of all authors. 17
