Over Twenty Years Trend of Chloride Ion Concentration in Lake Biwa
Papers from Bolsena Conference (2002). Residence time in lakes:Science, Management, Education J. Limnol., 62(Suppl. 1): 42-48, 2003 Over twenty years trend of chloride ion concentration in Lake Biwa Yasuaki AOTA*, Michio KUMAGAI1) and Kanako ISHIKAWA2) Institute of Nature and Environmental Technology, Kanazawa University, Kakuma, Kanazawa 920-1192, Japan 1)Lake Biwa Research Institute, Uchidehama, Otsu, Shiga 520-0806, Japan 2)Division of Applied Biosciences, Graduate School of Agriculture, Kyoto University, Kyoto 606-8502, Japan *e-mail corresponding author: [email protected] ABSTRACT Recent increase of chloride ion concentration in Lake Biwa was considered. Over the past 20 years' data at the North Basin of Lake Biwa showed that chloride ion concentration has been continuously increasing from 7.4 to 9.9 mg l-1 at 0.5 m depth from lake surface and from 7.3 to 9.9 mg l-1 above the bottom (depth of over 80 m from lake surface). This low level salinity indicated, how- ever, about 35% increase through 20 years. In this paper, we reported the trend and the tendency of chloride ion concentration at some locations and the change of climatic data through 20 years in Lake Biwa. In a short period within one year, chloride ion con- centration clearly fluctuated in the upper water layer. This fluctuation was mostly influenced by precipitation. Similar trend of chlo- ride ion concentration could be seen in the South Basin of Lake Biwa with much higher concentration than that in the North Basin. We also discussed the long-term changes of chloride concentrations in 5 major rivers with large catchment area, water level and precipitation. -

Twenty-four previously known, 2 new, and 4 unidentified species in 17 gen- era and 12 families are recorded. Three dubious literature records are also mentioned. All 30 con- firmed species, except Sanguinicolidae gen. sp. (Aporocotylidae), are described and figured. Life cy- cles are discussed where known. Philopinna kawamutsu sp. nov. (Didymozoidae) was found in the connective tissue between the vertebrae and the air bladder near the esophagus of Nipponocypris tem- minckii (Temminck and Schlegel) (Cyprinidae). Genarchopsis yaritanago sp. nov. (Derogenidae) was found in the intestine of Tanakia lanceolata (Temminck and Schlegel) (Cyprinidae). Asymphylodora innominata (Faust, 1924) comb. nov. is proposed for A. macrostoma Ozaki, 1925 (Lissorchiidae). A key to the families, genera, and species of these digeneans is provided. Host-parasite and parasite- host lists are given. Key words: adult digeneans, Trematoda, parasites, morphology, life cycle, Philopinna kawamutsu sp. -

Life: The Excitement of Biology 3(4) 231 Amber from Japan: a Nuclear Magnetic Resonance Study1 Joseph B. Lambert2, Allison J. Levy2, Nicole R. Rueb2, Truongan V. Nguyen2, Yuyang Wu3, and Jorge A. Santiago-Blay4 Abstract: Fifteen amber samples from Japan have been analyzed by nuclear magnetic resonance spectroscopy. The nine distinct geographical sources extend from the northern island of Hokkaido to the southern tip of the main island of Honshū. All but one sample gave the characteristic patterns of Group A amber. One of these, from Shiga Prefecture, gave variations of this spectral pattern suggesting a considerably younger or less fully matured condition within Group A. The fifteenth sample, from Mizunami in Gifu Prefecture, gave the clear pattern of Group B amber, which differs significantly from Group A in having an angiospermous (flowering) rather than a coniferous plant source. Key Words: amber, copal, Kuji, nuclear magnetic resonance spectroscopy Introduction Amber has been culturally important in Japan since antiquity. Wider appreciation of Japan as a major source of amber dates particularly from about 2006, when the Kaliningrad Amber Museum put on a major exhibit of Japanese amber (Sasaki 2006). Schlee (1990) and Aizawa (2002) have summarized the many Japanese sources of amber, which extend from the northern island of Hokkaido to the southern island of Kyushu, although most sources are on the eastern side of the main island of Honshū (Figure 1). The most productive region is from the vicinity of the town of Kuji at the northern end of Honshū in the Prefecture of Iwate (point 2 on Figure 1). -
Representations of Travel in Medieval Japan by Kendra D. Strand A
Aesthetics of Space: Representations of Travel in Medieval Japan by Kendra D. Strand A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Asian Languages and Cultures) in The University of Michigan 2015 Doctoral Committee: Emerita Professor Esperanza Ramirez-Christensen, Chair Associate Professor Kevin Gray Carr Professor Ken K. Ito, University of Hawai‘i Manoa Associate Professor Jonathan E. Zwicker © Kendra D. Strand 2015 Dedication To Gregory, whose adventurous spirit has made this work possible, and to Emma, whose good humor has made it a joy. ii Acknowledgements Kind regards are due to a great many people I have encountered throughout my graduate career, but to my advisors in particular. Esperanza Ramirez-Christensen has offered her wisdom and support unfalteringly over the years. Under her guidance, I have begun to learn the complexities in the spare words of medieval Japanese poetry, and more importantly to appreciate the rich silences in the spaces between those words. I only hope that I can some day attain the subtlety and dexterity with which she is able to do so. Ken Ito and Jonathan Zwicker have encouraged me to think about Japanese literature and to develop my voice in ways that would never have been possible otherwise, and Kevin Carr has always been incredibly generous with his time and knowledge in discussing visual cultural materials of medieval Japan. I am indebted to them for their patience, their attention, and for initiating me into their respective fields. I am grateful to all of the other professors and mentors with whom I have had the honor of working at the University of Michigan and elsewhere: Markus Nornes, Micah Auerback, Hitomi Tonomura, Leslie Pinkus, William Baxter, David Rolston, Miranda Brown, Laura Grande, Youngju Ryu, Christi Merrill, Celeste Brusati, Martin Powers, Mariko Okada, Keith Vincent, Catherine Ryu, Edith Sarra, Keller Kimbrough, Maggie Childs, and Dennis Washburn. -

Research Project Sites 1 Message from the Director-General The Research Institute for Humanity and Nature (RIHN) was established in April 2001 to conduct integrated research in the field of global environmental studies. In 2004, RIHN became one of the original members of the National Institutes for the Humanities (NIHU), as an Inter-University Research Institute Corporation. Environmental degradation can be understood as an imbalance in interactions between human beings and natural systems. Our mission is therefore to conduct solution-oriented research aimed at exploring how interactions between humanity and nature ought to be. RIHN conducts interdisciplinary research spanning the natural sciences, humanities, and social sciences, and transdisciplinary research, collaborating with various stakeholders in society. Fiscal year 2019 marks the fourth year of our Phase III Medium-Term Plan. Under the three Research Programs, and one Core Program, we conducted nine full research projects.
