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
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
The colonization of the lagoon by coral reef fish larvae was compared between two islands of French Polynesia, the atoll of Rangiroa and the high volcanic island of Moorea. In both cases the larval flux coming into the lagoon followed a daily cycle.
This paper describes the channels known as hoa which are characteristic of atoll land rims and of some islands on barrier reefs, where they often dissect previously more continuous reef-top sediment accumulations and conglomerate platforms. They are
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.
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,
Coral atolls are natural laboratories within which to examine ecological processes (Sachet, 1967; Lee, 1984). They are often isolated, in some cases little disturbed, and have a geologically recent history of terrestrial plant colonisation. Reef islands around the rim of most atolls are Holocene in age. They are composed of biogenic skeletal sediments and have developed since reef growth caught up with sea level which stabilized after post-glacial sea-level rise. Plant colonisation of most of these islands must have occurred over a period of no more than 6000 years.
In a typical High Island coral reef complex of French Polynesia (transect of Tiahura, Hoorea Island, Society Archipelago!, 73 species of decapod Reptantia and stomatopod crustaceans were collected. Over 9 stations localised along the transect, 3 different units of hard coral substrate of simi1ar volume (about 17 litres each), were sampled at each station. The results are discussed from two aspects : the first shows that at least 50 carcinologic species occur within the cavitary biotopes ; 16 species (mainly Xanthid crabs), represent more than 90% of all collected individuals.
Recent studies have shown that many coral reefs are capable of
yielding a total fish catch of 18- 24 T.Km-2 (Hill, 1978; Alcala,
1981; Munro, 1987). There are, however, no estimates for the
productivity and yield of fishes associated with coral reefs in
French Polynesia. This study was designed to determine the fisheries yield from a part of the fringing reef on the island of Moorea, French Polynesia.

The conservation status, ecology, and cultural importance of sea turtles at the three Polynesian atolls of Tokelau are presented. The green turtle, Chelonia mydas. is the most common species, occurring as a migrant breeder mostly during September through November. The hawks- bill, Eretmochelvs imbricata. is present in small numbers at all three atolls, but nesting is only known at Nukunonu Atoll. A third species, the loggerhead, Caretta caretta. has also been recorded on rare occasions.
Reef coral collections from American Samoa are in the National Museum of Natural History, Smithsonian Institution, Washington, D.C., and in the Hessisches Landesmuseum, Darmstadt, W. Germany. The author has a collection of 790 coral specimens for a total of 1547 items known to be from American Samoa.
A total of 177 species (including 3 species of non-scleractinian corals) belonging to 48 genera and subgenera (including the genera Millepora and Heliopora) known to date are listed with data as of frequency of occurrence and habitat.

The Tokelau Islands consist of three atolls (Atafu, Nukunonu and Fakaofo) approximately 500 km north of Western Samoa. Their numerous islets are formed mainly of coral sand and rubble with no standing freshwater. Sixty-one plant species have been recorded, 13 of these being introduced and 10 being adventives. There are three vegetation zones, the beach, the beach-crest, and the interior coconut/fern zone with the physiognomy of a humid tropical forest. Marine invertebrates have not been studied.
Species-numbers relationships in the McKean Island assemblage
of reef-building corals were investigated to discover how they changed along environmental gradients of the reef. For the purposes of the study, two gradients were identified a complex depth gradient and a wave exposure gradient.

It has been over twenty years since UNCLOS came into existence and twelve years since it came into force, in addition to fourteen years since the historic "Earth Summit" was convened in Rio de Janeiro in Brazil, yet the Pacific Small Island Developing States (SIDS) are finding it extremely difficult to deal with many cross-cutting and multiple issues relating to ocean management. The challenge for the Pacific SIDS is clear, successive international, regional and national initiatives
Conservation biology involves protection and management of biodiversity (Metfe and Carroll 1994). This integrated discipline requires both an understanding of an ecosystem and its associated threats, as well as an understanding of the management of the system as a resource. In order to
develop management techniques that can limit resource degradation, we need a clear understanding of the role of threats to the resources. The focus of this dissertation is assessing threats to resources, using coral reefs as a model
system.
