The very productive lagoon fisheries of Tarawa atoll changed greatly in recent decades as human development and intensive harvesting increased. Tarawa typifies the increasingly common condition of resource depletion and marine community structure change with expanding human activities and population growth. Fisheries-dependent reports have documented the change in fisher landings for nearly two decades. A comparison of fisheries-independent data collected during 1992-93 with data collected in 1977 allowed for documentation of large changes in important finfish resources in Tarawa Lagoon.
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
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.
French Polynesian Decapoda, restricted to shrimps, and Stomatopuda are inventoried from literature and unpublished fields collections.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 Gilbert Islands are a north-south chain of low coral islands, lying across the equator at about 172°-177° E longitude. The atolls, from north to south are Little Makin, Butaritari, Marakei, Abaiang, Tarawa, Maiana, Kuria, Aranuka, Abemama, Nonouti, Tabiteuea, Onotoa, Beru, Nikunau, Tamana, and Arorai. They are densely populated, and were under British Colonial Government until 1979, when they were granted independence, and now are the principal archipelago in the new republic of Kiribati.
