World-Wide Distribution of the Bryozoan Pectinatella Magnifica (Leidy 1851)
96 European Journal of Environmental Sciences WORLD-WIDE DISTRIBUTION OF THE BRYOZOAN PECTINATELLA MAGNIFICA (LEIDY 1851) ZUZANA BALOUNOVÁ1, EVA PECHOUŠKOVÁ1, JOSEF RAJCHARD1,*, VÍT JOZA1, and JAN ŠINKO2 1 Faculty of Agriculture, University of South Bohemia, CZ 370 05, České Budějovice, Czech Republic 2 Faculty of Fisheries and Protection of Waters, University of South Bohemia, CZ 389 01, Vodňany, Czech Republic * Corresponding author: [email protected] ABSTRACT Pectinatella magnifica (Leidy 1851) is an invasive freshwater colonial animal belonging to the phylum Bryozoa. It is native to the area east of the Mississippi River, from Ontario to Florida. Currently it occurs throughout North America and the first record for it outside that continent was for Bille near Hamburg in 1883. Later, it was found in the Elbe (Havel by Spandau), in Tegeler See, a pond in Wroclaw and in Silesia and Brandenburg. In addition, floatoblasts of P. magnifica were found in the upper Elbe in Germany in the 1950s. Then, P. magnifica spread to the area of Spandau in Berlin and the Oder, and Wroclaw. It is also recorded in Romania and Turkey. In France, it was recorded occurring in the area called Franche-Comté in 1994. Its occurrence in the Netherlands was first reported in 2003 and then each following year. The newest discoveries are for the Rhine basin in the area between Luxembourg and Germany. Recently, it was also recorded in the Czech Republic and Austria. Besides Europe and North America, it is also recorded in Japan and Korea. The statoblasts of P. magnifica are spread by flowing water, zoochory and probably also by anthropochory. -
Taxonomic Study of Freshwater Bryozoans from Jeju Island, Korea
Journal of Species Research 6(Special Edition):129-134, 2017 Taxonomic study of freshwater bryozoans from Jeju Island, Korea Hyun Sook Chae1, Hyun Jong Kil2 and Ji Eun Seo3,* 1Department of Food-Biotechnology, Woosuk University, Jeonbuk 55338, Republic of Korea 2Animal Resources Division, National Institute of Biological Resources, Incheon 22689, Republic of Korea 3Department of Eco-Biological Science, Woosuk University, Chungbuk 27841, Republic of Korea *Correspondent: [email protected] This study aims to investigate the freshwater bryozoans of Jeju Island off the Korean Peninsula for the first time. To date, twelve species has been reported from the mainland of Korea. However, no study of freshwater bryozoans has ever been conducted on Korean islands including Jeju Island, which is the largest island in Korea. Five species in three genera Fredericella, Plumatella and Stephanella, from Jeju Island are described. Of which, three species, Fredericella indica, Plumatella mukaii and P. rugosa, are new records of Korean bryozoan fauna. As a result of this study, the number of identified Korean freshwater bryozoans is now 15 species, including 12 phylactolaemates and three gymnolaemates.

STUDIES ON FRESH-WATER BRYOZOA, XVII. MICHIGAN BRYOZOA MARY D. ROGICK, College of New Roche lie, New Rochelle, N. Y. AND HENRY VAN DER SCHALIE, University of Michigan, Ann Arbor, Mich. INTRODUCTION The purpose of the present study is to record the occurrence of several bryozoan species from localities new to Michigan and other regions; to compile a list of the bryozoa previously recorded from Michigan; and to correct or revise the identifica- tion of some of the species collected long ago. Records published by various writers from 1882 through 1949 have reported the following bryozoa from different Michigan localities, sometimes under synonyms or outmoded names: Class ECTOPROCTA Order GYMNOLAEMATA * Family Paludicellidae 1. Paludicella articulata (Ehrenberg) 1831 ORDER PHYLACTOLAEMATA Family Cristatellidae 2. Cristatella mucedo Cuvier 1798 Family Fredericellidae 3. Fredericella sultana (Blumenbach) 1779 Family Lophopodidae 4. Pectinatella magnifica Leidy 1851 Family PRimatellidae 5. Hyalinella punctata (Hancock) 1850 6. Plumatella casmiana Oka 1907 7. Plumatella or bis per ma Kellicott 1882 8. Plumatella repens (Linnaeus) 1758 9. Plumatella repens var. coralloides (Allman) 1850 10. Plumatella repens var. emarginata (Allman) 1844 11. Stolella indica Annandale 1909 The recorded localities for the above list of bryozoa are named in Table I.

REISWIG Redpath Museum and Department of Biology, McGill University, 859 Sherhrooke Street West, Montre'al, PQ H3A 2K6, Canada Received October 5, 1993 Accepted December 17, 1993 RICCIARDI,A., and REISWIG,H.M. 1994. Taxonomy, distribution, and ecology of the freshwater bryozoans (Ectoprocta) of eastern Canada. Can. J. Zool. 72: 339-3 5 9. The freshwater Bryozoa (Ectoprocta) are one of the most poorly known faunal groups in Canada. A recent survey of 80 freshwater habitats in eastern Canada (from Ontario to Newfoundland) revealed 14 species of bryozoans, representing 56% of described species in North America. The greatest numbers of species and specimens were found in alkaline waters (pH 7.0-9.8) near lake outflows, wherever hard substrates were present. Paludicella articulata, Cristatella mucedo, Fredericella indica, and Plumatella fungosa are among the most frequently encountered, widely distributed, and eurytopic species. Pottsiella erecta and Plumatella fruticosa are rare, and new to eastern Canada. Lophopodella carteri, an exotic Asian species discovered in Lake Erie in the early 1930s, has become firmly established in the lower Ottawa and upper St. Lawrence rivers. Detailed notes on taxonomy, morphology, distribution, and ecology are given for each bryozoan. New limits of tolerance to water temperature, pH, and calcium and magnesium hardness are established for several species. A taxonomic key to the freshwater bryozoans of eastern Canada, including a key to statoblast types, is presented for the first time. -

Abstract Ts & P Prog Gram
ABSTRACTS & PROGRAM 25th – 28th May 2017 University of Vienna Vienna Austria Welcome to the 14th Larwood Symposium in Vienna! ‘Servus’ as we Austrians say. It’s my pleasure to welcome almost 50 colleagues and friends from 15 different countries to Vienna, the capitol of Austria. It is the third time the IBA will come to this city for exchange of new scientific results and new ideas for future research projects. In 1983, Norbert Vávra first invited our community to the 6th international meeting followed 25 years later by the 8th Larwood meeting organized by Norbert Vávra and Andrew Ostrovsky. With this meeting, Vienna will be the venue with most IBA-meetings so far. Kind of surprising considering that the amount of active bryozoologists was never very high when compared to other locations. Vienna is an extraordinary city and an excellent location for conferences and meetings. This is also reflected in the amount of international meetings in this city. Just in 2015 statistics count 3.685 congresses and business events. Organizing a meeting commonly turns out to be more work than expected and I’d like to thank all persons involved in making this meeting possible: Our secretaries Anita Morth and Doris Nemeth, our IT-technician Sonja Matus and my helping hands and students Hannah Schmibaur (who also designed the logo for this meeting), Nati Gawin, Philipp Pröts and Basti Decker. I hope that everyone will have a pleasant stay in Vienna and look forward to an exciting new IBA-meeting.

The Life of the Freshwater Bryozoan Stephanella Hina (Bryozoa, Phylactolaemata)
Schwaha et al. Zoological Letters (2016) 2:25 DOI 10.1186/s40851-016-0060-5 RESEARCH ARTICLE Open Access The life of the freshwater bryozoan Stephanella hina (Bryozoa, Phylactolaemata)—a crucial key to elucidating bryozoan evolution Thomas Schwaha1* , Masato Hirose2 and Andreas Wanninger1 Abstract Background: Phylactolaemata is the earliest branch and the sister group to all extant bryozoans. It is considered a small relict group that, perhaps due to the invasion of freshwater, has retained ancestral features. Reconstruction of the ground pattern of Phylactolaemata is thus essential for reconstructing the ground pattern of all Bryozoa, and for inferring phylogenetic relationships to possible sister taxa. It is well known that Stephanella hina, the sole member of the family Stephanelllidae, is probably one of the earliest offshoots among the Phylactolaemata and shows some morphological peculiarities. However, key aspects of its biology are largely unknown. The aim of the present study was to analyze live specimens of this species, in order to both document its behavior and describe its colony morphology. Results: The colony morphology of Stephanella hina consists of zooidal arrangements with lateral budding sites reminiscent of other bryozoan taxa, i.e., Steno- and Gymnolaemata. Zooids protrude vertically from the substrate and are covered in a non-rigid jelly-like ectocyst. The latter is a transparent, sticky hull that for the most part shows no distinct connection to the endocyst. Interestingly, individual zooids can be readily separated from the rest of the colony. The loose tube-like ectocyst can be removed from the animals that produces individuals that are unable to retract their lophophore, but merely shorten their trunk by contraction of the retractor muscles. -

The wildlife in the Ngorogoro Crater, near Serengeti National Park, in northeastern Tanzania is justly famous, but bryozoologists have an additionally compelling reason for visiting - freshwater bryozoans! In November, Dennis Gordon found himself standing in for a colleague as acting New Zealand Head of Delegation to the 15th Governing Board meeting of the Global Biodiversity Information Facility. The conference was held in Arusha, three hours drive from Ngorogoro Crater, where the delegates had a one-day safari. In the crater there is a lake and several large ponds, one of them by a toilet block. Although occupied by many hippopotamus, the pond has an accessible shallow area wherein are small rocks with freshwater leeches, bryozoans, and other invertebrates.
