Dinoflagellate
The Dinoflagellates (), also called Dinophytes, are a monophyletic group of single-celled eukaryotes constituting the phylum Dinoflagellata and are usually considered protists. Dinoflagellates are mostly marine plankton, but they are also common in freshwater habitats. Their populations vary with sea surface temperature, salinity, and depth. Many dinoflagellates are photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey ( phagotrophy and myzocytosis). In terms of number of species, dinoflagellates are one of the largest groups of marine eukaryotes, although substantially smaller than diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (for example, '' Oodinium'' and '' Pfiesteria''). Some dinoflagellates produce resting stages, called dinoflagellate cys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gambier Islands
The Gambier Islands ( or ) are an archipelago in French Polynesia, located at the southeast terminus of the Tuamotu archipelago. They cover an area of , and are made up of the Mangareva Islands, a group of high islands remnants of a caldera along with islets on the surrounding fringing reef, and the uninhabited Temoe atoll, which is located 45 km (28 mi) south-east of the Mangareva Islands. The Gambiers are generally considered a separate island group from Tuamotu both because their culture and language (Mangarevan language, Mangarevan) are much more closely related to those of the Marquesas Islands, and because, while the Tuamotus comprise several chains of coral atolls, the Mangareva Islands are of volcanic origin with central high islands. Administratively, the Gambier Islands are inside the Communes of France, commune of Gambier (commune), Gambier, which also includes several atolls in the Tuamotu Archipelago. The town hall (''mairie'') of the commune of Gambier is located o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Society Islands
The Society Islands ( , officially ; ) are an archipelago in the South Pacific Ocean that includes the major islands of Tahiti, Mo'orea, Moorea, Raiatea, Bora Bora and Huahine. Politically, they are part of French Polynesia, an overseas country of France, overseas country of the France, French Republic. Geographically, they form part of Polynesia. Name The term ''Society Islands'' was first used by Captain James Cook when he visited the Leeward Islands (Society Islands), Leeward Islands, a subgroup of six of the modern-day Society Islands, during his First voyage of James Cook, expedition to the south Pacific Ocean in 1769. It has been asserted that the name honors the Royal Society, the sponsor of his voyage, but this is disputed. Cook wrote in his journal: History Settlement The first Polynesians are understood to have arrived on these islands around 1000AD.

French Polynesia
French Polynesia ( ; ; ) is an overseas collectivity of France and its sole #Governance, overseas country. It comprises 121 geographically dispersed islands and atolls stretching over more than in the Pacific Ocean, South Pacific Ocean. The total land area of French Polynesia is , with a population of 278,786 (Aug. 2022 census) of which at least 205,000 live in the Society Islands and the remaining population lives in the rest of the archipelago. French Polynesia is divided into five island groups: the Austral Islands; the Gambier Islands; the Marquesas Islands; the Society Islands (comprising the Leeward Islands (Society Islands), Leeward and Windward Islands (Society Islands), Windward Islands); and the Tuamotus. Among its 121 islands and atolls, 75 were inhabited at the 2017 census. Tahiti, which is in the Society Islands group, is the most populous island, being home to nearly 69% of the population of French Polynesia . Papeete, located on Tahiti, is the capital of French ...

New Caledonia
New Caledonia ( ; ) is a group of islands in the southwest Pacific Ocean, southwest of Vanuatu and east of Australia. Located from Metropolitan France, it forms a Overseas France#Sui generis collectivity, ''sui generis'' collectivity of the French Republic, a legal status unique in overseas France, and is enshrined in a dedicated chapter of the French Constitution. The archipelago, part of the Melanesia subregion, includes the main island of Grande Terre (New Caledonia), Grande Terre, the Loyalty Islands, the Chesterfield Islands, the Belep archipelago, the Isle of Pines (New Caledonia), Isle of Pines, and a few remote islets. The Chesterfield Islands are in the Coral Sea. French people, especially locals, call Grande Terre , a nickname also used more generally for the entire New Caledonia. Kanak people#Agitation for independence, Pro-independence Kanak parties use the name (''pron.'' ) to refer to New Caledonia, a term coined in the 1980s from the ethnic name of the indi ...

Protists Described In 1981
A protist ( ) or protoctist is any eukaryotic organism that is not an animal, land plant, or fungus. Protists do not form a natural group, or clade, but are a paraphyletic grouping of all descendants of the last eukaryotic common ancestor excluding land plants, animals, and fungi. Protists were historically regarded as a separate taxonomic kingdom known as Protista or Protoctista. With the advent of phylogenetic analysis and electron microscopy studies, the use of Protista as a formal taxon was gradually abandoned. In modern classifications, protists are spread across several eukaryotic clades called supergroups, such as Archaeplastida (photoautotrophs that includes land plants), SAR, Obazoa (which includes fungi and animals), Amoebozoa and "Excavata". Protists represent an extremely large genetic and ecological diversity in all environments, including extreme habitats. Their diversity, larger than for all other eukaryotes, has only been discovered in recent decades throu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
