The arcid bivalve Anadara uropigimelana (te bun) is the most important shellfish resource in the central atolls of Tungaru (former Gilbert Islands), with a yearly catch of ca. 1400 tons on South Tarawa alone. Species of Anadara s.s. are also important in artisanal shellfisheries on several central Pacific islands. Tungaru atolls lying in the highly productive zone of equatorial upwelling harbor dense te bun beds, while those
Williamson and Sabath (1982) have demonstrated a significant relationship between modern population size and environment by examining atoll area and rainfall in the Marshall Islands. The present work seeks to extend that argument into prehistory by examining the relationship of ancient habitation sites and size of aroid pit agricultural systems to atoll land area and rainfall regime along the 1,500-3,500 mm precipitation gradient in the Marshall Islands.
This article provides a record of fish names from two locations in the central Pacific, these being the Vava'u Islands of Tonga, and Taveuni area in northern Fiji. The Handbook for the Collection of Fish Names in Pacific Languages by G.L. Barnett provided a method for the collection of these data during field work at the two places which culturally are part of West Polynesia. Interviews and discussions with fishers yielded a record of the Tongan language names and Fijian language names of approximately 50 fishes that occur in the waters of these islands.
Henderson island, a World Heritage Site in the Pitcairn group, south-central Pacific Ocean, has often been thought to have a pristine vegetation. Our archaeological investigations and field observations in 1991-1992, supported by recent observations in
1997, suggest the occurrence of former areas of Polynesian cultivation near to the North and East Beaches, and indicate that about 17 non-native vascular plant taxa have occurred.
French Polynesian Decapoda, restricted to shrimps, and Stomatopuda are inventoried from literature and unpublished fields collections. Number of species is 205 for the shrimps and 26 for the Stomatopoda. Within the shrimps, Caridea dominate with 170 species, mainly Alpheidae (57 species), Palaemonidae (46 species), and Pandalidae (29 species). Full literature and distribution in French Polynesia are indicated for each species.
Two species of sea turtles and eight lizards comprise the herpetofauna of Kapingamarangi Atoll; the giant Micronesian gecko (Perochirus scutellatus) is unknown elsewhere. The mourning gecko (Lepidodactylus lugubris), oceanic gecko (Gehyra
oceanica), and azure-tailed copper-striped skink (Emoia impar) are the most common and widespread species, being recorded on 100%, 97%, and 87% of the 31 islands, respectively. The stump-toed gecko (Gehyra mutilata) and the Pacific blue-tailed skink
Flying foxes (Pteropus spp) are important pollinators and seed dispersers in many island ecosystems. Populations of flying foxes have declined markedly on most islands in the South Pacific since the 1940's. One potential conservation strategy is to reintroduce bats on islands where they historically occurred. In this manner, the risk of species extinction due to local catastrophic events can be reduced. Ideally the source
The shorefishes of Ouvea, an isolated atoll in the Loyalty Islands group of New Caledonia, had not been surveyed prior to 1990. An extensive survey was conducted by ORSTOM between 1991 and 1992 to obtain baseline information on the shorefishes. A
total of 653 taxa among 72 families are now documented from this area. The most diverse families are the Labridae (69 species), Pomacentridae (58 species), Gobiidae (54 spccies),Serranidae (39 species), Chaetodontidae (31 species) and Apogonidae (28
The oceanic dispersal of plants and animals has been the focus of studies ever since organized natural history started in the Pacific, and the dispersal of terrestrial by sea rafting has been given due consideration. The finding of drift materials such as glass floats, tree trunks and seeds, is a common occurrence on the shores of Pacific Islands, but in most
cases the origin of such material is unknown or at least equivocal. Thus while the principle of sea rafted dispersal is known and reported at length, there is a need to document those
The study of dispersal processes of small mammals, and especially of rodents, has a wide range of applications and until recent years there were few publications discussing the
colonisation of 'oceanic' islands by small mammals (cf. Crowell, 1986; Diamond, 1987; Hanski, 1986;Heany, 1986; Lomolino, 1986).
What are the decapod crustacea known from French Polynesia? The answer to this, apparently simple question, would be very helpful for determinating the species collected during ecological studies. Moreover, from a biogeographical point of view, a check list of the species reaching this area, at the eastern limit of the Indo-West Pacific province, would be very interesting.
Fish communities in the lagoon of the Tikehau atoll were studied by only a few researchers. Harmelin-Vivien (1984) studied the distribution of the main herbivorous families (Scaridae and Acanthuridae) in the lagoon and on the outer slope to 30 m in depth. The total fish community of the outer slope was studied by Galzin (1985, 1987) at 12 m in depth. These studies were carried out in the southwestern part of the atoll. Spatial organization of coral associated fish community was studied throughout the lagoon by Morize et al. (1990). Most of the other
Ten caves in the makatea limestone of Mangaia, Cook Islands were explored and mapped, totalling over 3.7 km of passage. Of these, there was an apparent grouping by elevation that corresponds with previously described sea-level terraces in the makatea. Four caves have major level sections 10-20 m above sea-level, corresponding with a 14.5 m Pleistocene terrace. The high dimensions of these caves indicate downcutting during
The recorded flora of the raised phosphatic limestone island of Nauru in the equatorial Pacific Ocean consists of approximately 493 species. Only 59 are possibly indigenous, none of which are endemic. The balance is composed of ornamentals, weedy exotics, food plants, and a limited number of other useful cultigens. Twelve of the recorded species are either extinct or were never successfully established on Nauru.
This paper lists the vascular flora of the three atolls (Canton, Gardner, Hull) and five small islands (Birnie, Enderbury, McKean, Phoenix, Sydney) of the Phoenix Group,
located in the arid equatorial belt of the Central Pacific, based on extensive collections made in 1973 and 1975 and on previous records and collections. The flora includes 87
species in 36 families. Only 28 of the species (32%) are considered native. A further 60 species have been recorded in the literature, many of them deliberate introductions which
Nukutipipi atoll (5 km2), of volcanic origin 16-17 million years old on the Pitcairn (hot spot) Hereheretue line, presents a land flora and fauna of low diversity but with a Pisonia forest and hundreds of resident red-tailed tropic birds. Nukutipipi suffered from the 1983 hurricanes : destruction of vegetation and motu as well as sand lagoon mollusc populations. The north and south rims present original geomorphological structures.
During the period 1958-1964, the authors undertook soil and vegetation studies in the northern Marshall Islands as part of the University of Washington Radiation Biology Laboratory surveillance team. This team was responsible for monitoring levels of radiation in various components of the island environment and any effects on plant and animal life. The authors of this report were charged with the soils and vegetation components but assisted with collections in the aquatic ecosystems and some food plant materials.
Phosphatic limestones and associated soils occur on eight of the nine islands of Tuvalu, central Pacific. Deposits range from gram-size to >500,000 tons. Carbonate hydroxyapatite, dahllite, forms crustose cement about calcareous bioclasts which it sometimes replaces. Precise genetic relationship of rock to soil is unclear. Consolidated rock occurs as hardpan within phosphatic soil profiles, with unconsolidated phosphatic layers above and below. Phosphatization has occurred either as a continuous or episodic process within the vadose zone for at least 4000 years.
Jonathan Sauer (1961) remarked, in his Coastal Plant Geography of Mauritius, that the chance to study the coastal vegetation there was like being "admitted to a field worker's paradise"
and stressed that "most tropical coasts are beautiful and exciting, particularly to people concerned with natural processes . . .." The same can certainly be said for the tropical coasts of the often Edenized islands of the Pacific Ocean. Their "beauty and excitement" is considerably enhanced,
This monograph sheds light on the status of secondary plant cover, heretofore little known, on slopes between sea level and about 750m in the Marquesas Islands, a remote tropical Polynesian archipelago of high islands of volcanic origin situated in the dry tradewind zone of the South Pacific. Plant cover types are described and assigned to xerotropical, transitional and pluviotropical floristic zones determined in part by comparison with similar zones previously devised for Oahu Island, Hawaii.
