The ash has three roots, each of them sucking water from its own spnng. The first spring- Hvergelmir- is found in the ice cold North; next to the spring, the serpent Niohoggr is ceaselessly gnawing at the roots of the ash. The second spring­ Mimisbrunnr - is the source of wisdom and is guarded by Mimir. The third spring­ Uroarbrunnr - is guarded by three women, the Noms, which mete out man's thread of life.

It was the second parasitological meeting jointly organized by the Societies. The first Baltic-Scandinavian parasitological meeting "Parasitic Zoonoses and the Ecology of Parasites" was held in Lithuania in September 1994. The Symposium on "Ecology of Bird-Parasite Interactions" was organized to strengthen the professional links, and to exchange ideas and information between parasitologists, ecologists, evolutionary biologists and ornithologists in the field of ecology of bird-parasite interactions. The purpose of the meeting was to present and discuss results and to stimulate future research in the area as well as to develop such co-operative projects in bird ecology that take parasitism into consideration. Owing to focusing on a single taxonomic host group, the symposium provided a unique opportunity for extensive interdisciplinary discussions on the subject. The meeting attracted more than 60 persons from 18 European countries, USA and Australia, as will appear from the present proceedings. During the symposium, the fascinating parasite­ bird interactions were analysed ranging from a molecular level to the cdl:nmunity spectrum with most participants interested in interactions on individual level and in populations. Several general problems of ecological parasitology were discussed. For example, migration and parasite dispersal, host fitness and population consequences, impact of parasites on bird population dynamics, bias of sampling in bird parasitology, etc. The papers based on plenary lectures given by invited speakers as well as abstracts of oral and poster presentations, are published in this issue of the SSP Bulletin. We hope the contributions will be stimulating for the advancement of ecology, parasitology, ornithology and evolutionary biology as well as for the interaction of these biological sciences. On behalf of the organizing committee, we are pleased to express our deepest thanks to the invited lectures and other participants for their valuable contributions to the success of the symposium. We wish to record special thanks to the symposium sponsors: without this support the symposium would never have taken place. Support from the Scandinavian Society of Parasitology made it possible to produce the present issue of the Bulletin. Through an editorial process, some linguistic corrections have been introduced, but the individual authors are responsible for thepresented terminology, interpretations, etc. 28 September 1998 GediminasValkiiinas Hans-Peter Fagerholm iv CONTENTS Char seas< Belo.
