Colonisation of the Mariana Islands: New Evidence and Implications for Human Movements V 479
1 New evidence and implications ' for human movements in the Western Pacific John L. Craib Archaeologist Introduction Within the last five years, archaeological investigations on Saipan, ?inian and Guam has changed our understanding of the early period of human occupation in the Mariana Islands (Figure l). This work has not only extended the antiquity of human presence in these islands, it has provided a more detailed sample of the cultural assemblage asso- ciated with this early settlement. While increasing our knowledge of the prehistory of the Marianas, these new data, at the same time, offer important implications for human movement in the western Pacific. This paper provides a brief overview of recent fin- dings and discusses possible origins of the founding population in the Marianas and the implications this has for general movement within the western Pacific. Early sites in the Mariana Islands Two sites on Saipan, Chalan Piao and Achugao, are now dated to between 3000- 3600 cal BP; the calibrated age range at Unai Chulu, on Tinian, straddles 3000 BP. The assemblage recovered from these three sites include finely made pottery, much of it red- 478 V Le Pacifique de 5000 A 2000 avant le present /The Pacific from 5000 to 2000 BP I Figure 1 Mariana Islands in the Western Pacific.

Land Molluscs from the Northern Mariana Islands, Micronesia
Nat. Hist. Res., Special Issue, No. I: I I 3-119. March 1994. Land Molluscs from the Northern Mariana Islands, Micronesia Taiji Kurozumi Natural History Museum and Institute, Chiba 955-2 Aoba-cho, Chuo-ku, Chiba 260, Japan Abstract More than twenty-four species of land molluscs, belonging to 13 families and 20 genera were collected from the 9 islands of the northern Mariana Islands, and 22 species are recorded for the first time from the islands. Six introduced species were recognized, including Achatina fulica and its predators, Euglandina rosea and Gonaxis kibweziensis. Almost all of the genera are widely distributed on Micronesian islands. Only one species, Ptychalaea sp., may show dispersal from the northern area to the northern Marianas. Key words: Land molluscs, Ptychalaea, Achatina fulica, northern Mariana Islands. The northern Mariana Islands are located in survey routes (see Asakura et al., 1994). Land the western Pacific between 16°22' and snails were collected from litter layers, tree 20°32 'N.

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. -

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. -

J. Gen. Appl. Microbiol., 18, 433-454 (1972) COPROPHILOUS PYRENOMYCETES FROM JAPAN I KOUHEI FURUYA AND SHUN-ICHI UDAGAWA* Fermentation Research Laboratories, Sankyo Co., Ltd., Hiro-machi 1-chome, Shinagawa-ku, Tokyo 140 and *Department of Microbiology , National Institute of Hygienic Sciences, Kamiyoga 1-chome, Setagaya-ku, Tokyo 158 (Received July 13, 1972) For the purpose of these series of mycological survey, 220 dung samples of wild and domestic animals for determination of species of pyrenomycetous Ascomycetes were collected from various geographic regions of Japan, in- cluding Ryukyu and Bonin Islands. 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. -

Legal Claims to Newly Emerged Islands
Comments LEGAL CLAIMS TO NEWLY EMERGED ISLANDS If a new island arose from the sea, as is likely to occur between the Volcano and Mariana Islands, to which State would it appertain?This Comment examines four theories of international law through which States might attempt to claim new islands. One theory derives from the 1958 Geneva Conventions on the Law of the Sea. The others are the cus- tomary internationallaw doctrines of contiguity, occupation and discovery. After determining that in this location only occupation and discovery would be applicable,the Comment concludes with an analysis of whether a claim would be polit- ically feasible. There was a tremendous explosion as the liquid rock struck water and air together. Clouds of steam rose miles into the air. Ash fell hissing upon the heaving waves. Detonations shattered the air for a moment and then echoed away in the immensity of the empty wastes. But rock had at last been deposited above the surface of the sea. An island-visible were there but eyes to see, tangible were there fingers to feel-had risen from the deep.' In March, 1974, a Japanese fishing vessel was sailing approximate- ly 150 miles northwest of the Mariana Islands when it encountered a previously unknown area of water no more than ten feet deep.2 The fishermen reported their discovery to the Japanese Maritime Safety Agency, which radioed warnings of the shallow spot. The Agency also requested reports of any other spots discovered. In late 1975 the United States obliged, having found an area only 177 feet deep some nineteen miles from the previous discovery. -
New Spiders of the Families Tetragnathidae, Nephilidae and Clubionidae (Arachnida, Araneae) from Izu and Ogasawara Islands, Tokyo
Bull. Natl. Mus. Nat. Sci., Ser. A, 37(1), pp. 15–26, March 22, 2011 New Spiders of the Families Tetragnathidae, Nephilidae and Clubionidae (Arachnida, Araneae) from Izu and Ogasawara Islands, Tokyo Hirotsugu Ono Department of Zoology, National Museum of Nature and Science, 3–23–1, Hyakunin-cho, Shinjuku-ku, Tokyo, 169–0073 Japan E-mail: [email protected] (Received 29 October 2010; accepted 9 February 2011) Abstract Three new spiders of the families Tetragnathidae, Nephilidae and Clubionidae (Arach- nida, Araneae) from Hachijojima and Mikurajima Islands of the Izu Islands, and Chichijima Island of the Ogasawara Islands are described under the names, Leucauge nagashimai sp. nov. (Tetra- gnathidae), Nephila clavata caerulescens subsp. nov. (Nephilidae) and Clubiona oceanica sp. nov. (Clubionidae). Leucauge nagashimai resembles Chinese Leucauge bimaculata and liui, both de- scribed by Zhu, Song et Zhang (2003), but differs from the two species by the details of female genitalia, especially in the shape of spermathecae. Clubiona oceanica belongs to the species group of Clubiona hystrix defined by Deeleman-Reinhold (2001) and stands close to Clubiona maipai Jäger et Dankittipakul, 2010 from Thailand, Clubiona kuu Jäger et Dankittipakul, 2010 from Laos, Clubiona damirkovaci Deeleman-Reinhold, 2001 from Peninsular Malaysia and Clubiona hitchinsi Saaristo, 2002 from Seychelles Islands, but is distinguishable from these known species by the structure of female genitalia, especially the position of intromittent orifices and the condition of in- tromittent canals and in details of tibial apophysis and embolus of male palpal organ. Nephila clavata caerulescens is described for the populations of Nephila clavata on Hachijojima and Mikurajima Islands, which show a remarkable variation on the coloration of the body not mimic to the color pattern of vespid wasps.
