BRYOZOAN STUDIES 2019 Edited by Patrick Wyse Jackson & Kamil Zágoršek Czech Geological Survey 1 BRYOZOAN STUDIES 2019 2 Dedication This volume is dedicated with deep gratitude to Paul Taylor. Throughout his career Paul has worked at the Natural History Museum, London which he joined soon after completing post-doctoral studies in Swansea which in turn followed his completion of a PhD in Durham. Paul’s research interests are polymatic within the sphere of bryozoology – he has studied fossil bryozoans from all of the geological periods, and modern bryozoans from all oceanic basins. His interests include taxonomy, biodiversity, skeletal structure, ecology, evolution, history to name a few subject areas; in fact there are probably none in bryozoology that have not been the subject of his many publications. His office in the Natural History Museum quickly became a magnet for visiting bryozoological colleagues whom he always welcomed: he has always been highly encouraging of the research efforts of others, quick to collaborate, and generous with advice and information. A long-standing member of the International Bryozoology Association, Paul presided over the conference held in Boone in 2007. 3 BRYOZOAN STUDIES 2019 Contents Kamil Zágoršek and Patrick N.

The meeting was presided over by Tim Wood. The meeting was attended by 82 delegates from 17 different countries. 64 oral communications, together with 23 posters were presented. Of particular significance was the participation of younger delegates some of whom were supported through the IBA Travel Awards and The Palaeontological Association Grant-in-Aid. This volume contains sixteen papers presented at the Conference, and the editors and Association are most grateful to the Czech Geological Survey for willingness to publish these proceedings. The IBA conference volumes are a valued source of primary research on bryozoans and collectively have added considerably to the body of knowledge on this group since the first conference volume was published in 1968. The conference followed the usual organisational scheme and began with a pre-conference fieldtrip that visited many geological and cultural sites in Bohemia and Moravia. Led by Kamil Zágoršek the trip started from Budapest, Hungary where the group visited the Hungarian Natural History Museum before spending seven days travelling through central Europe. Devonian, Cretaceous and younger Eocene and Miocene successions were examined. Cultural activities included visits to significant mediaeval castles such as at Filakovo, the UNESCO World Heritage locations at Vlklinec and Rajsna, and two battlefields. The trip finished in Prague with a city tour. On arrival at Liberec the delegates congregated in a disused cinema for an ice-breaking party sponsored by the micro-brewery Albrecht, and the following morning the scientific sessions commenced in the AULA lecture theatre in Building G on the University campus. In total thirteen sessions were delivered during the programme, on different bryozoological topics including evolution and ecology, growth and morphology, bryozoans and climate change, bryodiversity, phylogeny, southern hemisphere bryozoans, reproduction and development, and fossil studies. The diversity of papers and posters covered all aspects of bryozoology with a wide geographical and geological coverage. On the first morning of the conference Eckart Hakansson delivered a keynote address on free-living cheilostome bryozoans. The mid-Conference trip took in a circular route that highlighted a number of important geological locations close to Liberec, as well as places of cultural and more-recent historical significance. The First stop was to Jested Hill where the party ascended a volcanic cone on top of which is perched a television and communications mast and centre. Following this, a cave system in local sandstone was visited – this is now a favoured haunt of local motorbike enthusiasts. Lunch was at the Cvikov Brewery where the operations were explained, and some of the resultant products drunk afterwards over a meal. In the afternoon the IBA group visited the breath-taking Panská Skála locality which is the most visited tourist site in the district – here columnar basalts erupted during the Paleogene cropout in spectacular fashion. While there the President took the opportunity to collect freshwater bryozoans in an adjacent pond. On the return journey to Liberec a short visit was made to a local glass producer. The Conference Dinner, which was held early during the meeting, took place in the atmospheric cavernous vaulted basement of the City Hall. Ellis Medals were presented by the President, Tim Wood to Dennis Gordon and Mary Spencer Jones; these are awarded to members who have made a major contribution to the bryozoological community. The announcement of the recipients was met by resounding cheering and clapping. 6 At the close of the meeting the outgoing President instituted Antonietta Rosso the incoming President who in turn presented him with an IBA Presidential Medal. Three Gilbert Larwood Awards were presented: to Marianne Nilsen Haugen for her poster on Reptadeonella in European waters, to Katerina Achilleos for her paper on biochemical pathways in calcification of marine invertebrates focussed on Cellaria immersa, and to Carolann Schack for her paper on depth gradients characterising polymorphism in New Zealand cheilostomes. The Post-Conference Field Excursion took place along the Croatian coast of the Adriatic Sea where participants led by Maja Novosel
