It is morphologically most similar to E. japonica (De Haan, 1835), found on the Japanese mainland, the Ryukyu Islands, Taiwan, the Russian Far East, Korea and China, but diagnostic is the proportionately broader and dorsally flattened carapace which usually lacks the fourth anterolateral tooth, the ornamentation of the epistome, the male first gonopod and its the coloration. The biology of the new species and the different interpretations concerning the systematics of Eriocheir are briefly discussed. Key words: Crustacea, Decapoda, Brachyura, Varunidae, Eriocheir, new species, Ogasawara Islands, Japan Introduction The Ogasawara (Bonin) Islands are composed of about 30 islands of various sizes, located to the south of the Izu Islands, and about 1000 km south of Japan. These islands are oceanic, having been formed by protrusions of ancient submarine volcanoes. Flatlands are rare and there are many steep cliffs on along the coasts. The climate is oceanic and subtropical. Because the islands have never being adjacent connected to the Japanese mainland or the continent since they were formed, endemism is high. Accepted by P. Castro: 2 Mar. 2006; published: 6 Apr. 2006 1.

Its identity was confirmed by morphological comparison and DNA extractions from herbarium specimens collected between 1914 and 1938. Results from the molecular phylogenetic analyses demonstrated that L. hostifolia belongs to the L. makinoana complex. In comparison with other members of the L. makinoana complex, the broadly ovate labellum, short dormancy period, and flowering from November to March are unique characteristics of L. hostifolia. Results from the molecular phylogenetic analyses also suggested that L. hostifolia has had a long-isolated history in the Bonin Archipelago and probably migrated from temperate East Asia.

Forest Structures, Composition, and Distribution on a Pacific Island, with Reference to Ecological Release and Speciation!
Pacific Science (1991), vol. 45, no. 1: 28-49 © 1991 by University of Hawaii Press. All rights reserved Forest Structures, Composition, and Distribution on a Pacific Island, with Reference to Ecological Release and Speciation! YOSHIKAZU SHIMIZU2 AND HIDEO TABATA 3 ABSTRACT: Native forest and scrub of Chichijima, the largest island in the Bonins, were classified into five types based on structural features: Elaeocarpus Ardisia mesic forest, 13-16 m high, dominated by Elaeocarpus photiniaefolius and Ardisia sieboldii; Pinus-Schima mesic forest, 12-16 m high, consisting of Schima mertensiana and an introduced pine , Pinus lutchuensis; Rhaphiolepis Livistonia dry forest, 2-6 m high, mainly occupied by Rhaphiolepis indica v. integerrima; Distylium-Schima dry forest, 3-8 m high, dominated by Distylium lepidotum and Schima mertensiana; and Distylium-Pouteria dry scrub, 0.3 1.5 m high, mainly composed of Distylium lepidotum. A vegetation map based on this classification was developed. Species composition and structural features of each type were analyzed in terms of habitat condition and mechanisms of regeneration. A group of species such as Pouteria obovata, Syzgygium buxifo lium, Hibiscus glaber, Rhaphiolepis indica v. integerrima, and Pandanus boninen sis, all with different growth forms from large trees to stunted shrubs, was subdominant in all vegetation types. Schima mertensiana , an endemic pioneer tree, occurred in both secondary forests and climax forests as a dominant canopy species and may be an indication of "ecological release," a characteristic of oceanic islands with poor floras and little competitive pressure. Some taxonomic groups (Callicarpa, Symplocos, Pittosporum, etc.) have speciated in the under story of Distylium-Schima dry forest and Distylium-Pouteria dry scrub.

24. Paleomagnetic Evidence for Northward Drift and Clockwise Rotation of the Izu-Bonin Forearc Since the Early Oligocene1
Taylor, B., Fujioka, K., et al., 1992 Proceedings of the Ocean Drilling Program, Scientific Results, Vol. 126 24. PALEOMAGNETIC EVIDENCE FOR NORTHWARD DRIFT AND CLOCKWISE ROTATION OF THE IZU-BONIN FOREARC SINCE THE EARLY OLIGOCENE1 Masato Koyama,2 Stanley M. Cisowski,3 and Philippe Pezard4 ABSTRACT A paleomagnetic study was made on the deep-marine sediments and volcanic rocks drilled by Ocean Drilling Program Leg 126 in the Izu-Bonin forearc region (Sites 787, 792, and 793). This study evaluates the sense and amount of the tectonic drift and rotation associated with the evolution of the Philippine Sea Plate and the Izu-Bonin Arc. Alternating-field and thermal demagnetization experiments show that most of the samples have stable remanence and are suitable for paleomagnetic studies. Paleomagnetic declinations were recovered by two methods of core orientation, one of which uses a secondary viscous magnetization vector of each specimen as an orientation standard, and the other of which is based on the data of downhole microresistivity measurement obtained by using a formation microscanner. Oligocene to early Miocene samples show 10° to 14° shallower paleolatitudes than those of the present. Middle Miocene to early Oligocene samples show progressive clockwise deflections (up to ~80°) in declination with time. These results suggest large northward drift and clockwise rotation of the Izu-Bonin forearc region since early Oligocene time. Considering previous paleomagnetic results from the other regions in the Philippine Sea, this motion may reflect large clockwise rotation of the whole Philippine Sea Plate over the past 40 m.y. INTRODUCTION several tectonic models have been proposed, a common consensus has not yet been achieved.

Fifteen species of Podospora (the Sor- dariaceae) from numerous collections are described and illustrated. Most of them were also obtained in living cultures. All species are new records in Japan. Generally speaking, animal dungs contain very rich nutritive components which may serve as growth factors for various types of microorganisms. The coprophilous fungi, one of such dung inhabitants, comprise a special group made up of members of several classes ranging through Myxo- mycetes to Basidiomycetes. In their pioneering studies, MASSEE and SAL- MON (1, 2) emphasized that 187 genera and 757 species from coprophilous occurrence had been listed in SACCARDO's Sylloge Fungorum in the early of the present century. These fungi have long attracted many mycologists for more than a hundred years, and a considerably large number of taxonomic papers have been published on them from various areas of the world. Investigations on this fascinating group of fungi were relatively few in Japan. The most extensive work is that of TUBAKI (3), who isolated 16 species belonging to the Hyphomycetes from dung sources in Japan.

When Islands Create Languages
Long – When Islands Create Languages WHEN ISLANDS CREATE LANGUAGES or, Why do language research with Bonin (Ogasawara) Islanders? DANIEL LONG Abstract This paper examines the role that the geographical and social factors of isolation (from the outside world) and intense contact (within the community) commonly associated with small island communities can play in the development of new language systems. I focus on fieldwork studies of the creoloid and Mixed Language of the Bonin (Ogasawara) Islands. Keywords Japan, Ogasawara, Bonin, Chichijima, language contact, Mixed Language, creoloid Why some linguists are attracted to islands Island societies can teach us many things about human language itself. How do children, for example, assemble a complete language (a creole) out of the imperfect ‘broken’ speech (a pidgin) used by their parents and all the other adults around them?1 Such seemingly impossible things do occur and research on language use in island communities helps us to understand the processes by which such improbable feats are accomplished. Other questions arise too. Are such pidgins and creoles the only types of language systems that can come from language contact or do other types exist? What role do island factors like isolation from the outside world and intense inner-contact among islanders play in language change? In other words, there is the question of whether island languages are more likely or less likely to change as compared to their mainland counterparts. In order to explore these issue, this paper examines evidence from the language systems of the Bonin (Ogasawara) Islands, and relates the study of such island languages to the study of broader topics like the study of human language in general, and the study of island societies.

The plant was first identified as Zeuxine sakagutii Tuyama on the basis of morphological and macromolecular characters. No nucleotide sequence divergences in the nuclear ribosomal DNA ITS and the two plastid regions (matK and trnL-F intron) were found between the Ogasawara plant and Z. sakagutii samples from the Ryukyu Islands and Hainan Island, China. This result indicates a recent, long distance dispersal of this species to Ogasawara. Z. boninensis Tuyama, described from Ogasawara, was considered to be extinct. We did not find any differences between Z.

The Archaeology of the Ogasawara Islands
The Archaeology of the Ogasawara Islands Received March 1983 SHlzua aDA INTRODUCTION HE 30 -ODD ISLANDS and shoals that comprise the Ogasawara Islands lie in an area 1000-1300 km south-southeast ofTokyo, extending from 24°14' to 27°45' north T latitude and 141 °16' to 142°26' east longitude. From north to south the group consists of the Mukojima Islands, the Chichijima Islands, the Hahajima Islands, and the Volcano Islands. Climatically the group belongs to the oceanic subtropics; however, due to warm-water currents in the area, the climate is tropical. Geographically the Ogasawaras are located in the center of an arc formed between the Izu Islands and the Marianas, per pendicular to Japan. The group is connected to Japan through the Izu Islands and also, through the Okinawan Islands and Taiwan, to Malaysia and India in the tropics. More over, it is also connected geographically in the South to the tropical Pacific islands of Micronesia and distant Polynesia (Fig. 1). From a study of documents of the Edo Period, it appears that the Ogasawara Islands were uninhabited through the eighteenth century. In European records from the same periods, the Ogasawaras are referred to as the Bonin Islands (apparently a corruption of the Japanese "munin" or "empty ofmen") and are noted as being devoid ofhuman occu pation. Today, however, from the results of archaeological research carried out in the South Pacific, it appears that Stone Age man was widely dispersed through the islands of the Pacific. Thus any consideration ofsuch questions as the polished stone adzes of Kita Iwojima; the agate, sandstone, and coral artifacts from Chichijima; and the bone and cowry-shell artifacts from Hahajima must take into account the navigational capabilities Shizuo Oda is a member of the Department of Culture, Tokyo Metropolitan Board of Education.
