These species are herein described in detail and illustrated by scanning electron microscopy. Nine species (23\% of total) are described as new (Electra asiatica, Callopora sarae, Conopeum nakanosum, Cauloramphus cryptoarmatus, Cauloramphus multispinosus, Cauloramphus niger, Stomachetosella decorata, Microporella luellae, and Celleporina minima), and 21 species (54\%) are reported for the first time from Japan. Species richness ranged from eight to 29 species per study site. A TWINSPAN analysis showed the species fell into nine groups defined by the local pattern of distribution. A cluster analysis of study sites based on similarity of species composition showed three faunistic groups distributed geographically: in Akkeshi Lake, along the eastern-central shore of the bay, and at the mouth of the bay. Species richness in estuarine Akkeshi Lake was low, with a species composition very different from the outer bay. Most cheilostomes were found on rock and shell substrata, but uncommonly occurred on concrete walls, algae, hydroids, tubes of polychaetes, other bryozoans, and anthropogenic debris. Of the 39 species found, 33 (85\%) contained embryos during the collecting periods, 2-7 June and 3-6 July 2004. The biogeographical composition of intertidal cheilostomes at Akkeshi Bay included species with Arctic-Boreal (28\%), Boreal (59\%), and Boreal-Subtropical (13\%) distributions. The overall species richness of intertidal cheilostomes was two-thirds that documented intertidally in a comparable study at Kodiak, Alaska, a locality 15 degrees higher in latitude. We attribute the lower richness at Akkeshi to differences in the nearshore marine environment between the two localities.}, keywords = {biodiversity, biogeography, bryozoa, Cheilostomata, genus, intertidal, islands, new, species, species richness, taxonomy}, isbn = {0022-2933}, url = {://000247967500005}, author = {Grischenko, A.

The epizoobiontic bryozoan fauna of Flustra foliacea (Linnaeus, 1758) was analysed on 51 sample stations kept in four German museums. The samples cover the entire North Sea and different time periods (1776-2008, mainly the period of 1904/1905 compared to 1980-87). Cluster analysis shows a differentiation into a northern and a southern North Sea assemblage. The northern assemblage is characterized by Amphiblestrum flemingii (Busk, 1854), Callopora dumerilii (Audouin, 1826) and Tricellaria ternata (Ellis \& Solander, 1786), while the southern North Sea is characterized by Electra pilosa (Linnaeus, 1767), Crisia eburnea (Linnaeus, 1758) and Plagioecia patina (Lamarck, 1816). Spatial separation approximately follows the 50 m depth contour. The temporal distribution patterns of bryozoans are discussed in terms of NAO (North Atlantic Oscillation) and temperature variations.
