Summary and Conclusions
This has been a very successful Symposium, the diverse contributions leading to many productive interactions between and within disciplines, but the absence of Russian ecologists is regretted and their presence would have resulted in a more complete picture of current knowledge. There were 170 participants from 13 nations and in addition to the five keynote addresses by invited speakers there were 106 papers, about half of them in the form of posters. No summary can be complete or unbiased and it would be invidious to single out individual authors by name, so I have not attempted to do this. However, I would like to acknowledge the five keynote speakers who have assisted me greatly with this final chapter by permitting me to incorporate into it their respective session summaries. Despite the title of the Symposium most of the contributions tend to deal with individual organisms or limited groups of organisms. I propose to start with the marine environment, its physics, chemistry, microbial components, algae, benthos, zooplankton, and higher consumers, as well as the interactions between them; then to discuss the ideas presented on the interactions between terrestrial and freshwater ecosystems; and, finally, the presentations on these ecosystems separately. Conclusions will be drawn as appropriate in the course of the discussion and also in a final section.
