Ostracode Research Activities inJAPAN
Correspondent: Takahiro Kamiya <takamiya@kenroku.kanazawa-u.ac.jp>
Hayashi, Keiichi. I am workingon the non-marine ostracode biostratigraphy and correlation of Lower Cretaceous formations in southwestern Japan and southwestern Korea.
Hiruta, Shin-Ichi. I am working on a faunal study of myodocopids from Kyushu.
Ikeya, Noriyuki. I am continuing to work on the database of Japanese Ostracoda with members of the Japanese Society of the Study of Ostracoda (JASSO), which will be completed by 2000. A CD-ROM will be issued on the occasion of ISO 2001 at Shizuoka. While supervising six students on the taxonomy, ecology and evolution of marine Ostraocda, I am still workingon the administration as Dean of the combined Physical Science and Engineering College. Students and their topics: Gengo Tanaka, Natural history of littoral Ostracoda from the West Pacific; Yuriko Nakao, Phylogeny of Ostracoda by muscle arrangements on appendages; Yusaku Kaseda, Paleobiological study of the genus Hemicytherura (Ostracoda, Crustacea); Masako Kato, Taxonomy and faunal analysis of the littoral Ostracoda from Antarctica; Hiromasa Kondo, Cuticular structure of fossil and living ostracode carapaces; Kiyotaka Hatanaka, Classification of Hemicytheridae (Ostracoda) from Australia.
Irizuki, Toshiaki. I am continuing to work mainly on two projects, 1) migration and speciation of Neogene ostracodes from Japan in association with global climatic changes, and 2) shell chemistry, taphonomy and paleoecology of Holocene ostracodes. This year I will start to investigate Recent Chinese marine ostracode faunas with N. Ikeya, Wang Pingxlan, Zhao Quan-Hong and Zhao Bao-Chun. I currently have one graduate student, Katsura Yamada, who is working on cyclic changes of late Pliocene ostracode faunas in northern Japan.
Ishizaki, Kunihiro. I am working on ostracodes from Late Cenozoic paleoenvironments. I am currently working on ostracodes from Kagoshima Bay and a supplimentary study of ostracodes in the Sendai area, northeastern Japan.
Kamiya, Takahiro. I have an eight-month sabatical this year and am visiting the UK (Dave Horn), Belgium (Koen Martens), Germany (Dietmar Keyser), Italy (G. Bonaduce) and the USA (Tom Cronin) from March to November, 1999. I am currently working on two projects, 1) the phylogeny of cytheracean and cypridacean ostracodes based on DDP (Differentiation of Distribution pattern of Pore-systems), and 2) the phylogeny of some cytheracean ostracodes by mt-DNA analysis. I am working with several graduate students. Hirokazu Ozawa (D3) is working on the Recent ostracode faunas in the Sea of Japan, discussing the relationship of water mass structure and the faunas, both for Plio-Pleistocene and Recent, and will complete his doctoral thesis next January. Toru Ishii (D1) has completed his master thesis on the study of the phylogeny of species of Loxoconcha based on the DDP and its post-Miocene distribution around Japan. Toshihiro Fujita (M2) is studying the mode of molting of cytheracean ostracodes, Ishizakiella and Spinileberis, and has already found fantastic results on the regulation and cyclicity. Takeharu Ishizaki (M1) is working on the phylogenetic relationship of superfamilies of Podocopida by DDP. Daisuke Higashi (M1) is working on the Recent ostracode faunas in the inner bay and shallow marine environments of southeastern Asia. Mayumi Obata (M1) is working on the taxonomy, ethology and population ecology of Neonesidea (Bairdiacea).
Tabuki, Ryouichi. I am studying 1) the cology and taxonomy of reef ostracodes from the Ryukyu Islands, Japan, 2) the submarine cave ostracodes in the Ryukyu Islands, Palau Islands and Philippine Islands, and 3) predation scars on the carapaces of benthic ostracodes in the Ryukyu Islands. I am working with several graduate students. T. Takamine is writing a masters thesis on the ostracode fauna and sedimentary environment of the Pleistocene Chine Sand, Okinawa Island. Y. Nikawadori is writing a graduate thesis on the predation scars on carapaces of ostracodes from the Pleistocene Chine Sand, Okinawa Island.
Tsukagoshi, Akira. I am studying the segmentation (with Andrew Parker, Australian Museum) and homology of the urosome on ostracoda. Recently I have concentrated my work on the soft anatomy of Platycopa, which is very good material for understanding the ostracode body plan. With a postgraduate student, I am describing brackish-water species from the mouth of the Obitsu River, Chiba Prefecture. This work will include descriptions of one new genus and three new species, along with 17 genera and 21 species. I guide two postgraduate students: Shigetaka Tamaguchi (Institute of Geology, The University of Tokyo) and Yuriko Nakao (College of Humanity and Sciences, Nihon University). S. Yamaguchi finished a study using molecular analysis to analyze the relationships of the genus Ishizakiella populations around Japan. Now he is interested in higher taxonomh of Ostracoda using molecular and morphological analysis. Y. Nakao is involved in research on the brackish-water ostracod and foraminiferal facies in the mouth of the Obitsu River, Chiba Prefecture, in view of seasonal and decadal changes. She will move to Shizuoka University after April 1999. I will also be moving to Shizuoka University after April 1999.
Yajima, Michiko. I finished the Hilgendorf Exhibition at five museums in Japan. I continue to study the history of paleontology in order to introduce the new movement of history of paleontology in America and England since the 1970’s and to establish a good base of ostracodology in Japan.
Yumoto, Michiaki. I have researched the influence of the ENSO (El Nino-South Oscillation) and global climate chane upon tropical cyclone activity in the northwestern Pacific. So I am now suspending my work on ostracodes.
