Ogea Levu
Ogea Levu (pronounced ) is a coral island on a barrier reef in Fiji's Southern Lau archipelago. With an area of , it is situated at 19.18° South and 178.47° West, east of Fulaga. It has a maximum altitude of . A area covering both Ogea Levu and nearby Ogea Driki is the Ogea Important Bird Area. The Important Bird Area covers the entire range of the near threatened Ogea monarch. The makatea forest and Ogea monarch habitat of the island contribute to its national significance as outlined in Fiji's Biodiversity Strategy and Action Plan. The people of Ogea are known for their happy and carefree approach to life, and love laughter and merry-making wherever they are gathered. They work hard in their daily lives, mainly in planting root crops, and fishing in their rich fishing grounds around both their islands which are surrounded by magnificent reefs and coral atolls. The chief of Ogea is traditionally known as the Matua Tabu i Tui Nayau, Tui Ogea Tui or TUI may refer to: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when matu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiji
Fiji ( , ,; fj, Viti, ; Fiji Hindi: फ़िजी, ''Fijī''), officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about 110 are permanently inhabited—and more than 500 islets, amounting to a total land area of about . The most outlying island group is Ono-i-Lau. About 87% of the total population of live on the two major islands, Viti Levu and Vanua Levu. About three-quarters of Fijians live on Viti Levu's coasts: either in the capital city of Suva; or in smaller urban centres such as Nadi—where tourism is the major local industry; or in Lautoka, where the sugar-cane industry is dominant. The interior of Viti Levu is sparsely inhabited because of its terrain. The majority of Fiji's islands were formed by volcanic activity starting around 150 million years ago. Some geothermal activity st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lau Islands
The Lau Islands aka little Tonga (also called the Lau Group, the Eastern Group, the Eastern Archipelago) of Fiji are situated in the southern Pacific Ocean, just east of the Koro Sea. Of this chain of about sixty islands and islets, about thirty are inhabited. The Lau Group covers a land area of 188 square miles (487 square km), and had a population of 10,683 at the most recent census in 2007. While most of the northern Lau Group are high islands of volcanic origin, those of the south are mostly carbonate low islands. Administratively the islands belong to Lau Province. History The British explorer James Cook reached Vatoa in 1774. By the time of the discovery of the Ono Group in 1820, the Lau archipelago was the most mapped area of Fiji. Political unity came late to the Lau Islands. Historically, they comprised three territories: the Northern Lau Islands, the Southern Lau Islands, and the Moala Islands. Around 1855, the renegade Tongan prince Enele Ma'afu conq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archipelago
An archipelago ( ), sometimes called an island group or island chain, is a chain, cluster, or collection of islands, or sometimes a sea containing a small number of scattered islands. Examples of archipelagos include: the Indonesian Archipelago, the Aleutian Islands, the Lakshadweep Islands, the Galápagos Islands, the Japanese archipelago, the Philippine Archipelago, the Maldives, the Balearic Islands, the Åland Islands, The Bahamas, the Aegean Islands, the Hawaiian Islands, the Canary Islands, Malta, the Azores, the Canadian Arctic Archipelago, the British Isles, the islands of the Archipelago Sea, and Shetland. Archipelagos are sometimes defined by political boundaries. For example, while they are geopolitically divided, the San Juan Islands and Gulf Islands geologically form part of a larger Gulf Archipelago. Etymology The word ''archipelago'' is derived from the Ancient Greek ἄρχι-(''arkhi-'', "chief") and πέλαγος (''pélagos'', "sea") thr ...

Altitude
Altitude or height (also sometimes known as depth) is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. Vertical distance measurements in the "down" direction are commonly referred to as depth. In aviation In aviation, the term altitude can have several meanings, and is always qualified by explicitly adding a modifier (e.g. "true altitude"), or implicitly through the context of the communication. Parties exchanging altitude information must be clear which definition is being used. Aviation altitude is measured using either mean sea level (MSL) or local ground level (above ground leve ...

Ogea Driki
Ogea Driki (pronounced ) is a coral atoll covering approximately in Fiji's Southern Lau Group. It is south of Ogea Levu and east of Fulaga. A area covering both Ogea Driki and Ogea Levu is the Ogea Important Bird Area. The Important Bird Area covers the entire range of the near threatened Ogea monarch. It is the farming and fishing ground for the Ogean villagers who own the island and subdivided into farming lots as well as beaches. It has no residential house but are always used by the Ogeans as a place to sleep overnight for fishing purposes or any other means. It has a rich bundled fish corals and reef.

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the Program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking.

Near-threatened Species
A near-threatened species is a species which has been categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature as that may be vulnerable to endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of re-evaluating near-threatened taxon at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of vulnerable which are plausible or nearly met, such as reduction in numbers or range. Near-threatened species evaluated from 2001 onwards may also be ones which are dependent on conservation efforts to prevent their becoming threatened, whereas before this conservation-dependent species were given a separate category ("Conservation Dependent"). Additionally, the 402 conservation-dependent taxa may also be considered near-threatened.

Ogea Monarch
The Ogea monarch or versicolored monarch (''Mayrornis versicolor'') is a species of bird in the family Monarchidae. It is endemic to two islands, Ogea Driki and Ogea Levu, in the Lau Group of south eastern Fiji. Its natural habitat is subtropical or tropical moist lowland forests. The species is little known, it feeds on insects and is thought to breed around July. Alternate names for the Ogea monarch include the Fiji versicolored monarch, Mayr's flycatcher, Ogea flycatcher and versicolored flycatcher. Status The species is not thought to be threatened by habitat loss, instead it is considered vulnerable due to its tiny range and the prospect of introduced predators An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived ther ... hunting it.

Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic component, abiotic processes—deposition (geology), deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic component, biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over .

Atoll
An atoll () is a ring-shaped island, including a coral rim that encircles a lagoon partially or completely. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical oceans and seas where corals can grow. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Two different, well-cited models, the subsidence and antecedent karst models, have been used to explain the development of atolls.Droxler, A.W. and Jorry, S.J., 2021. ''The Origin of Modern Atolls: Challenging Darwin's Deeply Ingrained Theory.'' ''Annual Review of Marine Science'', 13, pp.537-573. According to Charles Darwin's ''subsidence model'', the formation of an atoll is explained by the subsidence of a volcanic island around which a coral fringing reef has formed. Over geologic time, the volcanic island becomes extinct and eroded as it subsides completely beneath the surface of the ocean. As the volcanic island subsides, the coral fringing reef beco ...
