This volume is dedicated to Professor N. u;: "Pete" Riser, a friend and colleague who has encouraged all, and trained some of us in the art of nemertean biology VII Preface The nemerteans are a fascinating, common and often locally abundant group of invertebrates, yet for long have attracted the attention of only a handful of scientists. In recent years, however, increasing numbers of people have developed diverse research interests in the group with the result that our knowledge of these worms has rapidly advanced. Clearly there is a need for a regular series of international meetings where individuals working on these animals can meet to exchange ideas, review developments concerning nemertean biology and freely discuss future proposals. The first such meeting was held in Philadelphia during December 1983. Twenty-seven scientists from eight countries participated in the Second International Meeting on Nemertean Biology, held at the Tjarno Marine Biological Laboratory, Sweden, 11-15 August 1986. The meeting was divided into five sessions: two dealt with ecological studies, two with nemertean taxonomy, and the final session covered aspects of general biology. A total of 26 papers was presented; four, by N. Anadem, G. Berg, 1. Bierne, and 1.M. TurbeviIIe, were for different reasons not submitted for inclusion in this volume. Three additional presentations were made on behalf of B. Kulikova, E. N. WiIImer, and Z. Yin, all of whom were unable to participate in the meeting. Two evening workshops parallelled the major session topics. The Ecology workshop, chaired by P. Roe and 1. 1. McDermott, dealt with the problems associated with quantitative sampling of nemertean populations and with the need for investigating feeding ecology and digestive physiology. The value of using wide-ranging techniques in these studies was discussed, and it was concluded that keys for field identification of the more common/abundant species from different areas of the world would be most useful. The Taxonomy workshop, chaired by
