Introduction The present paper is intended to report the results of the author's studies on the flora of rust fungi in the Ryukyu Archipelago, including Tokara IsIs., Satsunan IsIs., Amami IsIs., Okinawa IsIs. and Sakishima IsIs. The intensitive studies on the rust fungi froln the Ryukyu Islands were begun *Contributions from Laboratory of Phytopathology, Division of Agriculture, Home Econo­ mics & Engineering, University of the Ryukyus, no. 11, also, Contributions from the Laboratories of Phytopathology and Mycology, Faculty of Agriculture, Tokyo University of Education. no. 48. ** Division of A'griculture, Home Economics & Engineering. s. SHIMABUKURO in April '1953, when Dr. Naohide Hiratsuka, who is the authority of Uredinology, came to University of the Ryukyus as a visiting Professor. Thereafter, the author started to study on the present topic under his direction. From October 1958 to July 1959, the author had an opportunity to receive his suggestions and criticisms at Hiratsuka Laboratories of Phytopathology and Mycology at Tokyo, as a dispatched research worker of University of the Ryukyus. The number of specimens of rust fungi examined is ab.out 3,000. These specimens are all kept in the Hiratsuka Herbarium, Tokyo, Japan, with duplicated thereof deposited in the Herbarium of University of the Ryukyus. It is a pleasure for the author to express his appreciation to Prof. Dr. Naohide Hiratsuka of Tokyo University of Education, under whose direction the present work was executed, for his useful suggestions and criticisms. Acknowledgements are also due to Dr. Genshu Asato, President of the University of the Ryukyus for making available facilities of the University in order that this research might be carried out. He is also indebted to the late Prof. Takashi Naito (Kagoshima, Japan), Prof. Sumi­ hiko Hatsushima (Kagoshima University), Dr. J. Ohwi (National Science Museum, Tokyo, Japan), Messl's. Tetsuo Amano and Shinjun Tawada of the Government of the Ryukyu Islands for identification of host plants of the fungi, and to Messrs. Yoshima Niiro and Masao Tamori for their faithful assistance on the present investigationa The present work has been supported by a Grant-in-Aid for Scientific Research by the University of the Ryukyus (1954-59) and by a Grant-in-Aid for Developmental Research of the Department of Education (1955-56, no. 21016) (Tokyo), to the directors of which the author wishes to take this opportunity of extending his sincere thanks. II. Geological and climatic description of the Ryukyu Archipelago The Ryukyu Archipelago, treated in this thesis, will include islands numbering more than one hundred and forty, which are located on the curvilinear chain between southern end of the Kyushu mainland and the northeastern end of Formosa. The Archipelago is 1287 kilometers in length and is located within the area lat. 24"­ 31 °51' N. and long. 123°-131° E. The archipelago can he divided into the following five groups: 1) Tokara Islands, 2) Satsunan Islands (Osumi Islands), 3) Amami Islands, 4) Okinawa Islands, and 5) Sakishima Islands (Miyako Islands, Yaeyama Islands). From the standpoint of the geological structure, Dr. Koto (C-3) and Dr. Hanzawa (c-l) advocates that Ryukyu Archipelago consists of three longitudinal zones. The islands belonging to the three zones are as follows: A. The Outer Zone (Tertiary and Quaternary)-I) Tanegashima Island, 2) Mageshima Island, 3) Kikaishima Island, 4) Okierabu Island, 5) Most of the middle and southern part of Okinawa Island and the dependent islets located in the eastern ocean, 6) The greater part of Iriomote Island, 7) Kuroshima Island of Yaeyama Islands, 8) Hateruma Island and 9) Yonaguni Island. B. The Middle Zone (consisting mostly of the Paleozoic stratum)-l)' Yaku­ sihma Island, 2) Amami-oshima Island, 3) 'rokunoshima Island, 4) Yoronshima Island, 5) Most of the northern, and a small part of the middle and southern Oki­ nawa Island, 6) Iheya Island, 7) Izena Island, 8) Kouri Island, 9) Iejima Island, 10) Sesoko Island, 11) Yagaji Island, 12) Ishigaki Island, 13) Kohama Island, 14) Taketomi Island and 15) Northeastern of Iriomote Island. l!'lora of Rust Fungi In the Ryukyu Archipelago 3 C. The Inner zone (mostly Volcanic Zone)-l) Northern part of Tokara Islands (Takeshima, Kuroshima and Iwoshima Islands), 2) Kuchinoerabu Island, 3) Southern part of Tokara Islands (Nakanoshima, Suwanoseshima, Akusekishima, Takarashima and Kotakarashima Islnds), 4) Iwotorishima Island, 5) Aguni Island, 6) Kumejima Island, and 7) Senkaku Islands. 1. Tokara Islands Tokara Islands are located within the area from lat. 31° N. to lat. 28°46' N. and from long. 128°51' E. to long. 130°30' E. Tokara Islands run in the direction of northeast to southwest, and are a part of the Middle Zone which consist of Volcanic Zones. The geographical elements of each island belonging to the Tokara Islands are as follows: i Circumference 2 Highest Islands Locality (km) Area in km i mountain (m) I Lat. 30°49' N.

Mshima-mura is located in lat. 30° N. northward and Jitto-son southward. Mishima­ mura consists of the three islands, Takeshima Island, Iwojima Island and Kuroshima Island. Takeshima Island is located in southwest of Kagoshima city and is 80 kilometers from the city. This island is closest one to the Kyushu mainland. The island runs from east to west, and is approximately 5 kilometers long' and approximately 2 kilometers wide. Its outstanding features are its volcanic origin and its plateau type topography. The seashore consists largely of cliffs. There are two mountains, called Magome-dake (228 m.) and Takahira-dake (180 m.). These mountains consist mostly of pyroxene-andesite and Basalt. -------> 4 S.

  • Nansei Islands Biological Diversity Evaluation Project Report 1 Chapter 1
    Introduction WWF Japan’s involvement with the Nansei Islands can be traced back to a request in 1982 by Prince Phillip, Duke of Edinburgh. The “World Conservation Strategy”, which was drafted at the time through a collaborative effort by the WWF’s network, the International Union for Conservation of Nature (IUCN), and the United Nations Environment Programme (UNEP), posed the notion that the problems affecting environments were problems that had global implications. Furthermore, the findings presented offered information on precious environments extant throughout the globe and where they were distributed, thereby providing an impetus for people to think about issues relevant to humankind’s harmonious existence with the rest of nature. One of the precious natural environments for Japan given in the “World Conservation Strategy” was the Nansei Islands. The Duke of Edinburgh, who was the President of the WWF at the time (now President Emeritus), naturally sought to promote acts of conservation by those who could see them through most effectively, i.e. pertinent conservation parties in the area, a mandate which naturally fell on the shoulders of WWF Japan with regard to nature conservation activities concerning the Nansei Islands. This marked the beginning of the Nansei Islands initiative of WWF Japan, and ever since, WWF Japan has not only consistently performed globally-relevant environmental studies of particular areas within the Nansei Islands during the 1980’s and 1990’s, but has put pressure on the national and local governments to use the findings of those studies in public policy. Unfortunately, like many other places throughout the world, the deterioration of the natural environments in the Nansei Islands has yet to stop.

E-mail: [email protected] Abstract A new species, Gastrodia kuroshimensis (Orchidaceae: Epidendroideae: Gastrodieae), from Kuroshima Island, Kagoshima Prefecture, Japan, is described and illustrated. The outlined floral morphology indicates a close affinity to G. fontinalis, but it is easily distinguished by several characteristics, such as the cleistogamous floral condition, smaller perianth tube size and the anther cap joined with the column. Key words: Gastrodia, Japan, mycoheterotrophy, Ryukyu Islands, taxonomy Introduction The genus Gastrodia Brown (1810: 330; Gastrodieae, Epidendroideae) is a group of mycoheterotrophic orchids that consists of ca. 90 acceptable species (Hsu et al. 2016). It is distributed throughout the temperate and tropical regions of Asia, Oceania, Madagascar and Africa (Chung & Hsu 2006, Cribb et al. 2010, Tan et al. 2012). The genus is characterized by fleshy tubers, the absence of leaves, as well as the union of its sepals and petals, and the production of two mealy pollinia that lack caudicles. Many species of Gastrodia section Codonanthus (Schlechter 1911, Tuyama 1967) produce inflorescences that are 3–15 cm in length at flowering (Chung & Hsu 2006). In addition, as is the case with most other mycoheterotrophic species, they occur in a small population and appear for a short reproductive period (Tuyama 1982, Suetsugu et al.

E-mail: [email protected] Kagoshima prefecture is located at the southern end of Kyushu, in one of Japan’s most rainy zones, with an annual average rainfall of over 2,300 mm. The majority of the prefectural land is covered with special soils, including “shirasu,” which is easily collapsible volcanic ejecta. Geologic features of Kagoshima include major calderas created by large-scale volcanic eruption, or the Aira Caldera and Ata Caldera, and “shirasu” plateaus, which are formed with pyroclastic deposits that gush from the volcanoes. These special topographic and geologic features are the cause of frequent sediment related disasters, such as slope failures or debris flow which wreak havoc on the prefectural citizens almost every year. Considering these natural characteristics, the prefecture takes comprehensive disaster control measures from both structural and nonstructural perspectives, including the construction of sediment control dams and other facilities, and the provision of information concerning danger zones and disaster prevention to prefectural citizens. This paper explains the Kagoshima prefectural government’s comprehensive sediment disaster control measures and describes the future efforts

The Progress Report of the 1999 Survey of the Research Project 137 “Social Homeostasis of Small Islands in an Island-zone” A COMMENT ON THE GEOLOGICAL FORMATION OF THE MISHIMA ISLANDS (TAKESHIMA, IOUJIMA AND KUROSHIMA) AS INFERRED FROM THEIR FRESHWATER CRUSTACEAN FAUNAS Hiroshi SUZUKI Abstract Freshwater crustacean faunas of the Mishima Islands, which constitute Takeshima, Ioujima and Kuroshima, were investigated. Three species, Caridina typus, Macrobrachium lar and Geothelphusa dehaani were recorded. The geological formation of the Mishima Islands was discussed, with notes on the biology and distribution patterns of their freshwater crustacean faunas. It is revealed that the three Islands were connected to the Chinese mainland about 1.0 million years ago, wherein only Takeshima had been submerged by sea-level rising that exterminated its G. dehaani population. Key words: crustacean fauna, formation process, Geothelphusa dehaani, Mishima Island, sea-level ris- ing Introduction The composition of crustacean fauna inhabiting the inland waters of islands was noted to coincide with geological history, life history of organisms, and so on. In the Ryukyu Islands lo- cated between the Kyushu Island and Taiwan, SHOKITA (1979, 1996) discussed the formation of the freshwater crustacean faunas, particularly the origin of the Japanese freshwater crabs, by comparing the composition and geographical distribution of the crustacean fauna inhabiting the inland waters of the Islands. In addition, he speculated that the ancestral species of the freshwater crustaceans, especially the landlocked and true freshwater species, already existed on the Ryukyu Islands about 1.0 Ma (million years ago), in stead of later immigration via the last land bridge linking the Ryukyus with the Chinese mainland.
