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.

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.

Most of the 96 national monuments designated under U.S. law
are on land. The majority are managed by the National Park
Service, though some are administered by the Bureau of Land
Management and other agencies. At this point neither the
name of the proposed Mariana Trench Marine National Monu-
ment (MTMNM) nor the management structure has been de-
termined. For guidance one could review the process of the
recently designated Papahanaumokuakea Marine National
Monument (PMNM), which is placed within the purview of the

Actions taken - or not taken -... will have a profound bearing on the future... The world lacks neither the financial resources nor the technological capabilities... What is missing is a sense of urgency, human solidarity and collective interest (2007/2008 Human Development Report).

Healthy marine resources require healthy, intact ecosystems. Marine and coastal ecosystems are highly productive and deliver various goods and services that support communities and economies, including food security, clean water, recreational
opportunities and other benefits. Effective area-based protection, through MPAs, helps maintain ecosystem health and productivity, while safeguarding social and economic
More than 20 cetacean species are known to exist in the
Pacific Islands Region, which encompasses the U.S. Exclusive

the entire Hawaiian Archipelago. Johnston Atoll. Kingman Reef and Palmyra Atoll. Baker and Howland Islands. Jarvis Island. American Samoa. Wake Island, Guam, and the Commonwealth of the
Northern Mariana Islands, totaling some 5.8 million km2 of ocean.
Many of the species present are poorly studied throughout their
Fishers have changed their methods from wading in the shallows to the use of sail and paddle canoes, and dinghies with outboard motors. This has resulted in greater coverage of the area where sea cucumbers live, more regular fishing, access to remote areas and the capacity to transport greater catches. Loss of much larger numbers of sea cucumbers from many areas as a result of this increased fishing pressure reduces the chances of adults remaining at densities high enough for effective reproduction.
This guide provides essential information to better understand
the role of marine protected area networks to achieve marine

According to conventional wisdom, small, fast-growing fish are impossible to overfish because their populations are so large and grow so quickly. Yet we are now seeing disquieting signs that conventional wisdom is wrong. Most significantly, scientists are reporting ocean predators emaciated from lack of food, vulnerable to disease and without enough energy to reproduce. Scrawny predatorsdolphins, striped bass, and even whaleshave turned up along coastlines around the world. Recreational fishermen are losing both their target fishand their bait.
