Preface The VIIIth International Rotifer Symposium was organized by Elizabeth S. Wurdak at St. John's University in Collegeville, Minnesota, USA during the week of June 22, 1997. It was the first rotifer symposium held outside Europe. Ninety-seven participants from 22 countries distributed over 4 continents attended. Following the tradition of earlier symposia, the conference was divided into oral sessions, poster sessions and workshops. Contributions were initially grouped into ecological studies, population structure, genetics, mating, phylogeny, biogeography, systematics, habitat, life history, biotechnology, culture, and cell biology. Morning and afternoon sessions began with an invited review followed by individual presentations of recent research findings. The presentations were punctuated by discussions over coffee. Home movies of rotifer behavior were screened in the evening amidst lively talk and amusement over the antics of male brachionids. At the mid-week banquet the assembled rotiferologists paid their respect to two international-known scientists for their long-term commitment to research on rotifers: Professors Ludmillia Kutikova (Russia) and Birger Pejler (Sweden). Dr Kutikova was present and accepted, with much graciousness, a certificate of achievement and the brief speech made by Bob Wallace on her behalf. The family of rotiferologists provided a hardy round of applause. A similar tribute to Dr Pejler, who because of a sudden illness had to cancel his plans to attend the meetings, follows this preface. During breaks and after formal sessions participants were free to explore the lakes, woodlands and prairie which surround St. John's University and to enjoy the hospitality offered by Br. Willie's Pub, the SJU summer events staff and the City of St. Cloud. Highlights of the meeting, other than the presentations, were the Mississippi River cruise on board the Anne Bonnie, picnic at the Stearns County Park along the River, banquet and dance at the College of Saint Benedict, post -conference excursions to Lake Itasca State Park and the Twin Cities of Minneapolis and Saint Paul. The success of the conference was a result of the hard work of the organizers, the exemplary cooperation of the participants, financial support from private donors, industry (i.e., Aquaculture Systems®, Chlorella Industries®) and assistance from the CSB/SJU Biology Department and the Science Hall Secretarial Staff. Many things have changed since the previous rotifer meeting. Rotifers have gone into space and, unlike earlier symposia, the VIIlth Rotifer Symposium was somewhat unique in that it had a unifying theme, the comparative approach, which can be traced through the contributions included in this volume. Following we highlight some examples of this theme within specific papers. In an invited review, microplankton responses to habitat disturbance in arctic lakes are compared to their responses in temperate lakes for which more extensive data are available. In another contribution the effects of disturbance on the rotifer community within an experimental lake are documented and the progress of recovery after habitat restoration is followed. Manipulated and unmanipulated lakes in the same geographical area are contrasted. The effect of colonization history and nutrient levels on zooplankton assemblages are explored in separate reports. Several studies examine spatial and temporal variability in rotifer abundance, and community structure in relation to variations in biotic and abiotic factors along gradients in natural settings, others approach these questions in an experimental way. Population responses to diet and chemical signals are tested in the field and through manipulation of laboratory cultures. The reproductive strategy of different rotifer taxa is investigated, by attempts to correlate egg size with life history parameters in order to evaluate the adaptive merits of large versus small eggs. The status of various rotifer taxa and species boundaries are reexamined in the light of results obtained by the most recent biochemical and molecular approaches, and other modern techniques (scanning electron microscopy, and cladistics and numerical techniques). The broader issue of the relationships of the Rotifera to other invertebrate taxa is taken up in a number of provocative papers. The distribution of Rotifera in remote geographical regions is explored by several authors. All these papers reflect the wide diversity of approaches, methods of analysis and conclusions that have been the hallmark of the rotifer symposia since their inception.
