As of 1969, the scientific community had no general information on the natural history of Namoluk Atoll in the Eastern Caroline Islands of Micronesia. The only significant published source for the atoll was an ethnographic and linguistic account provided by the German physician.
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.
The island was first mentioned by Roggeveen in 1722
(JOURDAIN 1970), but visits became regular only during the
XlXth century. An evangelist, of the "London Missionary
Society" settled down in 1829 (NEWBURY 1986), which supposes
that exchanges with the outside were regular at that time.
This probably explains the presence of bird specimens
collected outside the Scientific Expeditions (e.g. description of Ptilinopus purpuratus chalcurus in 1859 by GRAY).

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.

Rangiroa is the largest atoll in the Tuamotu Archipelago, and since the institution of a regular air service, the most accessible; yet in common with other Tuamotuan atolls it has rarely been visited by scientists and is barely mentioned in the literature. Dana (1849) published brief notes following the Wilkes Expedition; but the only full account is that by Agassiz (1903). Agassiz's descriptions are, however, verbose and imprecise, and marred by misinterpretations of major atoll features.
Fais (Tromelin) is an elevated coral island, surrounded by interrupted cliffs 15-20 meters high, lying some 140 miles east of Yap Island, at latitude 9'46' N, longitude 140'31' E in the western Caroline Islands. It has an area of 2.8 square km, and has a population of about 300 people, Micronesians, speaking a dialect of the Ulithi-Woleai tongue. As with many such raised coral islands, valuable calcium phosphate deposits occur on Fais, the greater portion of which was removed and exported during the period of Japanese rule (1914-1945).

The Northern Line Islands consists of four atolls aligned on
an an axis which runs from south east to north west. The three southern islands Christmas (Kiritiraati), Fanning (Tabuaeran) and Washington (Teraina) have permanent populations and are part of the Republic of Kiribati. The fourth island, Palmyra, on the north end of the chain, is an unoccupied U.S. possession.

The islands of the southern Cook and Austral groups in
the South Pacific exhibit astonishing differences in geology
and topography, even between closely adjacent islands of
similar ages. Some are sea-level atolls, others have low
fringes of Pleistocene raised reefs, and others substantial
rims of elevated mid-Tertiary limestones, locally known as
makatea. On some islands the relief of the makatea is
subdued, but on others it is dominated by eroded volcanics,
sea-level swamps, and vertical limestone walls. Sixty years
Located at 148°15' West and 15°50' South, in the northwesternmost part of the Tuamotu archipelago (Central Pacific), Makatea island is isolated from its nearest
neighbouring atolls, Rangiroa and Tikehau by about 80 km, and it is 245 km from its closest volcanic neighbour, Tahiti. This island rises at least 3,500 m above the sea floor.
During participation in part of the Fairbridge Expedition
to New Guinea, February to May, 1969, I had opportunity to visit 17 islands and cays east of the New Guinea mainland for sufficient time to assemble reasonably complete collections oi their terrestrial reptilian fauna. The purpose of this paper is to present the results of that survey. Fairbridge (1971 ) has previously published a brief report on the expedition and. a more detailed one is in preparation.

From 0900 on 17 June to 0615 on 19 June 1965 Caroline Atoll was visited by a field party from the Pacific Ocean Biological Survey Program (POBSP) of the Smithsonian Institution. The field party, led by Sibley, collected and made observations on vascular plants, fish, reptiles, mammals, and birds. All islands with the exception of the northern two-thirds of Nake were visited. Prior knowledge of the biota of Caroline Atoll is very scant, deriving almost entirely from the visits of F. D. Bennett in 1835, Devoy in 1875, and the U.S.S. Hartford in 1883.
Island ecosystems have proven to be particularly sensitive to
human disturbances (Bourne 1975; Byrne 1980; Jarvis 1979). This was first noted by Charles Darwin in the explanation of his theory of natural selection (Byrne 1980). Since then, qualities of insular species have been examined by various authors in an attempt to understand the basis for island vulnerability.

Christmas island3, the largest atoll in the world in terms of
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.

Satawal is a small flat coral island in the west central Caroline Islands about 1050 km east-south-east of Yap Island, at latitude 7'21' N, longitude 147'02' E. Although its surface is locally somewhat irregular, its greatest height is not more than about 4 meters above mean low water. Its long axis is about east-west and its area is 1.3 square km. It is surrounded by a fringing reef upward of 100 meters wide. It has no lagoon, so would be classified according to Tayama's scheme as a table reef. From the viewpoint of land ecology it is an atoll.
Canton Atoll has a single passage between the ocean and lagoon and lias conspicuous environmental gradients from that passage to the back lagoon. These gradients include the physiography of the lagoon floor, water quality, and the diversity and abundance of corals, fishes, and mollusks. The gradients can apparently be attributed either directly or indirectly to circulation
and water motion within the lagoon. Those oceanographic characteristics can, in turn, be attributed to the geological history of the atoll, including some human modification of the pass configuration.
The avifauna of the Marshall and Gilbert Islands and the sur-
Rarotonga and Aitutaki form the summits of separate
volcanic masses rising from depths of 4000 m, at which depth
the cones are 45-55 km in diameter (Summerhayes and Kibblewh
1966, 1967).The lower slopes of the cones average 15-25
increasing to 30 in the upper 750 m and becoming very steep
the surface reef is approached. The Mauke-Aitutaki line of
islands is thought to be of early Tertiary age: the surface
volcanics are much eroded, with a subdued topography, or are
capped with limestones (Wood, 1967; Wood and Hay, 1970). On
This paper is a somewhat revised and updated version of a report, written in 1973 after our 9-day visit, at the request of Mr. Marlon Brando, proprietor of Tetiaroa Atoll, and published here with his accord. The original version was based on that visit to the atoll, as explained in the introduction. It was supplemented by a few observations called from herbarium specimens and field notes of Dr. Gerrit Wilder, who visited the island briefly on March 12, 1925 and August 30, 1929, and of E. H. Quayle, of the Whitney Expedition, who stopped there on November 19-21, 1921.
