“…These factors have gradually decreased the biodiversity of the area, and many marine organisms have become endangered. Although many native and relict species of the last glacial epoch from the ancient East China Sea are found in the Seto Inland Sea (Botton et al 1996;Futahashi 2011;Hamaguchi et al 2013), other invasive alien and indigenous species have been discovered where human activity has led to the development of industrial areas along the coast (Iwasaki et al 2004). Therefore, since 2008 we have been conducting a long-term study to monitor benthic species diversity at various tidal flats to promote the conservation of native marine fauna in the Seto Inland Sea and its adjacent marine areas supported by the Ministry of the Environment Monitoring Sites 1000 Project and the Japan Long Term Ecological Research Network.…”

DNA barcoding of flat oyster species reveals the presence of Ostrea stentina Payraudeau, 1826 (Bivalvia: Ostreidae) in Japan

Background: DNA barcoding is an effective method of accurately identifying morphologically similar oyster species. However, for some of Japan's Ostrea species there are no molecular data in the international DNA databases. Methods: We sequenced the mitochondrial large subunit ribosomal DNA (LSrDNA) and cytochrome c oxidase subunit I (COI) gene of five known and two unidentified Ostrea species. Phylogenetic comparison with known Ostrea species permitted accurate species identification by DNA barcoding. Results: The molecular data, which were deposited in an international DNA database, allowed for a clear distinction among native Ostrea species in Japan. Moreover, the nucleotide sequence data confirmed that O. stentina (Atsuhime-gaki) inhabits Kemi and Ibusuki, Japan. Conclusions: This is the first record of O. stentina in Japan. These results provided for accurate species identification by DNA barcoding of the taxonomically problematic species O. futamiensis, O. fluctigera, O. setoensis and O. stentina in Japan.

“…Nevertheless, the ecosystem of tidal flats is under the threat of destruction by reclamation, modification of shore, invasion of exotic species, etc., in many places (cf. Wada et al 1996, Iwasaki et al 2004, Sato & Koh 2004, Sato 2006. Above all, we need to know what kinds of species occur and how they are kept at the habitats on the tidal flats, in order at least to preserve these species and healthy ecosystem on the tidal flats.…”

As a social activity in "Korea and Japan Joint Symposium on Biology of Tidal Flats 2009" held in Sucheon, Jeollanamdo, the southern part of South Korea, most of the participants to the symposium joined the surveys with the purpose of making a list of macrobenthic fauna that occur on Suncheon Bay Tidal Flats with approximately 1,200 ha in total area between June 21 and 23, 2009. In this survey, sixteen species of bivalves, twenty species of gastropods, one species of chiton, fourteen species of polychaetes, eight species of crabs, and three species of other animals were collected, and identified by the participants. Among these sixty-one species, two species of macrobenthic invertebrate animals including gastropod, Ellobium chinense, and crab, Sesarmops intermedius, are listed in the latest Red List of the Ministry of Environment of the Republic of Korea, and eight species of them including five species of potamidid gastropods are listed in that of the Ministry of Environment, Japan. The results of this survey indicate that the ecosystem on the tidal flats in Suncheon Bay are still healthy, and preserved almost in their original conditions, due to the serious efforts of the people in Suncheon City and the municipal authorities.

“…Along with the rest of the world, the number of species introduced into Japan has also continued to increase, with the most dramatic change after the 1960s paralleling that of San Francisco Bay (Iwasaki et al, 2004;Otani, 2012).…”

With five large and several small ports, Osaka Bay is heavily industrialized rendering the introduction of marine species that are not native to Japan inevitable. It presents, therefore, an ideal model locality to investigate the presence and persistence of introduced marine and estuarine species. We used the results obtained from surveys by citizen scientists undertaken between 2010 and 2013 to investigate the temporal and spatial patterns in numbers of introduced species. The results show remarkable temporal consistency in numerical diversity with between 11 and 15 introduced species being recorded every year. There were, however, strong spatial differences with tendencies for greater numbers of introduced species in the inner Bay and for lower numbers in the outer Bay. We analyzed the factors responsible for these patterns statistically using a generalized linear model (GLM). The optimal model implicated salinity and the number of native species. Because the salinity of Osaka Bay lies within the tolerance range of all the introduced species, it was discounted as a factor limiting introductions into the Bay. This implies that, interestingly, the actual number of native species is the most important limiting factor. This is then a real-world validation of the ecosystem resistance hypothesis. In this study, we analyzed data from three independent sources. We used data resulting from censuses of intertidal organisms (i.e., marine and brackish fishes, invertebrates, algae and vascular plants) undertaken by the Committee on Biological Surveys in Osaka Bay (see Ishida et al., 2015). In addition to these biotic data, the results of a survey of the Bay's water quality also form part of our analysis. These results were obtained by local governments. Furthermore, we included data on the number of ships arriving in the Bay from the Ministry of Land, Infrastructure, Transport and Tourism to give an idea of the potential arrival of introduced species in both ballast water and on ships' hulls.
