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.

This report lias been prepared on behalf of the Environment Service, Cook Islands as part of an ongoing monitoring programme of reef health of the fringing reef of Rarotonga. The
initial work was earned out in 2000 and this is the first subsequent sampling and report since that baseline study.

Millions of visitors to public aquariums and thousands of snorkelers and divers across the globe are amazed by the diversity of life on coral reefs. Looking to replicate
this marine wonderland, an increasing number of them have
created a "living aquarium" at home, unaware of the impact this
is having on species and the lives of people in far-flung regions.

Tongatapu, like Tahiti, was visited by many early
European navigators and was one of the first of the South
Pacific islands to be charted in any detail. Though it was
discovered (and named Amsterdam Island) by Tasman in
January 1643 (Sharp 1968, 152-158), the first comments on
the sand cays of the surrounding reefs were made by Cook
during his second voyage, with the Resolution and Adventure,
in October 1773. On this occasion Cook spent less than a
week at Tongatapu, anchored in the northwest, and commented

The International Coral Reef Action Network (ICRAN), established in the year 2000, is a collaborative effort working to halt and reverse the decline in health of the world's coral reefs. ICRAN was established by the United Nations Environment Programme (UNEP), WorldFish Center (formerly ICLARM), World Resources Institute (WRI), UNEP-World Conservation Monitoring Center (UNEP-WCMC), Global Coral Reef Monitoring Network (GCRMN), International Coral Reef Initiative (ICRI) Secretariat, Coral Reef Alliance (CORAL) and the Secretariat of the Pacific Regional Environment Programme (SPREP).

A great deal of deep-sea biodiversity is concentrated around features known as seamounts. Seamounts are like underwater islands - mountains that rise 1,000 meters or higher from the seabed but do not break the ocean surface. Although they have not been comprehensively mapped, it is estimated that there may be more than 100,000 seamounts worldwide. Almost half of these are believed to lie in the Pacific Ocean. To date, less than one percent of known seamounts have been comprehensively studied. The largest mountain range on planet Earth is beneath the ocean the Mid-Atlantic Ridge.

Almost half a billion people live within 100 km (60 miles) of coral reefs where they benefit from fisheries, wave and storm surge protection, and tourist income. With the worldwide coastal
population expected to double by 2050, coral reefs will be facing increased pressure from unmanaged development along coasts. Unplanned coastal developed is not only a serious threat

Coral reefs are vital ecosystems, providing a source of income, food arid coastal protection for millions of people; arid recent studies have shown that coral reef goods and services provide an annual net benefit of US$30 billion to economies worldwide

Scientists have identified an area called the Coral Triangle within the Indo-Pacific - its boundaries defined by marine zones containing 500 or more species of reef-building coral. This region covers all or part of six countries: Indonesia (Central and Eastern), Malaysia (Sabah), Papua New Guinea, Philippines,
Solomon Islands and Timor-Leste. Certain neighboring countries – including Australia, Fiji, New Caledonia and Vanuatu - contain rich coral biodiversity, but with somewhat lower numbers.

In most tropical countries, coral reef ecosystems provide coastal populations with a number of goods and services. However, a variety of anthropogenic practices threatens reef health and therefore jeopardizes the benefits flowing from these goods and services. These threats range from local pollution, sedimentation, destructive fishing practices and coral mining, to global issues such as coral bleaching.

Coral reef fisheries are a vital source of protein for coastal communities throughout the tropics. Coral reefs contain over 4,000 species of fish as well as other edible invertebrates and contribute about one-quarter of the total marine catch in developing countries. Exploitive
fishing, which includes overfishing and destructive fishing, occurs on most of the world’s reefs. It yields short-term economic benefits for fishers, but endangers the long-term sustainability of fishing and other reef-dependent industries
