Styloniscus Manuvaka
''Styloniscus manuvaka'' is a species of terrestrial isopod endemic to the islands of Rapa Nui and Rapa Iti. Its name is an epithet in the Rapa Nui language that translates roughly to "Canoe Bug". The name references the Canoe Bug Hypothesis which holds this species colonized these islands alongside ancient Polynesians via transplanted "Canoe Plants" such as banana, taro, and breadfruit. While this species is presently known only by relict populations in caves on Rapa Nui, its status on Rapa Iti is unknown. Another "Canoe Bug", ''Hawaiioscia rapui'', is the only other terrestrial isopod species native to Rapa Nui. ''Styloniscus manuvaka'' is in need of conservation measures, as its persistence is likely threatened by a combination of habitat loss, non-native species, and global climate change. The Darwin200 project will survey for this species and other potential canoe bug species on Rapa Nui, Pitcairn, and Mangareva Mangareva is the central and largest island of the Gam ...

Woodlouse
A woodlouse (plural woodlice) is an isopod crustacean from the polyphyleticThe current consensus is that Oniscidea is actually triphyletic suborder Oniscidea within the order Isopoda. They get their name from often being found in old wood. The first woodlice were marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. They have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape (conglobate) as a defensive mechanism; others have partial rolling ability, but most cannot conglobate at all. Woodlice have a basic morphology of a segmented, dorso-ventrally flattened body with seven pairs of jointed legs, specialised appendages for respiration and ...

Easter Island
Easter Island ( rap, Rapa Nui; es, Isla de Pascua) is an island and special territory of Chile in the southeastern Pacific Ocean, at the southeasternmost point of the Polynesian Triangle in Oceania. The island is most famous for its nearly 1,000 extant monumental statues, called '' moai'', which were created by the early Rapa Nui people. In 1995, UNESCO named Easter Island a World Heritage Site, with much of the island protected within Rapa Nui National Park. Experts disagree on when the island's Polynesian inhabitants first reached the island. While many in the research community cited evidence that they arrived around the year 800, there is compelling evidence presented in a 2007 study that places their arrival closer to 1200. The inhabitants created a thriving and industrious culture, as evidenced by the island's numerous enormous stone ''moai'' and other artifacts. However, land clearing for cultivation and the introduction of the Polynesian rat led to gradual defo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapa Iti
Rapa, also called Rapa Iti, or "Little Rapa", to distinguish it from Easter Island, whose Polynesian name is Rapa Nui, is the largest and only inhabited island of the Bass Islands in French Polynesia. An older name for the island is Oparo. The total land area including offshore islets is . As of the 2017 census, Rapa had a population of 507.Répartition de la population en Polynésie française en 2017 Institut de la statistique de la Polynésie française The island's highest point is at elevation at Mont Perahu.

Hawaiioscia Rapui
''Hawaiioscia rapui'' is a species of woodlouse endemic to the island of Rapa Nui. The specific epithet honors Sergio Rapu Haoa, a humanitarian, archaeologist, anthropologist, and politician of Rapanui descent who aided research terms studying this species. It persists as a relict population near the mouths of caves on the island, and is in dire need of conservation. It faces threats such as habitat reduction, non-native species competition, and global climate change. Styloniscus manuvaka is the only other native Isopod on the island, and faces the same perils.

Pitcairn Islands
The Pitcairn Islands (; Pitkern: '), officially the Pitcairn, Henderson, Ducie and Oeno Islands, is a group of four volcanic islands in the southern Pacific Ocean that form the sole British Overseas Territory in the Pacific Ocean. The four islands— Pitcairn, Henderson, Ducie and Oeno—are scattered across several hundred miles of ocean and have a combined land area of about . Henderson Island accounts for 86% of the land area, but only Pitcairn Island is inhabited. The islands nearest to the Pitcairn Islands are Mangareva (of French Polynesia) at 688 km to the west and Easter Island at 1,929 km to the east. The Pitcairn Islanders are a biracial ethnic group descended mostly from nine ''Bounty'' mutineers and a handful of Tahitian consorts—as is still apparent from the surnames of many of the islanders. The mutiny and its aftermath have been the subject of many books and films. As of January 2020, the territory had only 47 permanent inhabitants. History P ...

Mangareva
Mangareva is the central and largest island of the Gambier Islands in French Polynesia. It is surrounded by smaller islands: Taravai in the southwest, Aukena and Akamaru in the southeast, and islands in the north. Mangareva has a permanent population of 1,239 (2012) and the largest village on the island, Rikitea, is the chief town of the Gambier Islands. The island is approximately long and, at , it comprises about 56% of the land area of the whole Gambier group. Mangareva has a high central ridge which runs the length of the island. The highest point in the Gambiers is Mount Duff, on Mangareva, rising to along the island's south coast. The island has a large lagoon in diameter containing reefs whose fish and shellfish helped ancient islanders survive much more successfully than on nearby islands with no reefs. History Mangareva was first settled by Polynesians in the first millennium CE. While carbon dating has so far only dated settlements to 1160-1220, there is evi ...
