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.

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 ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Nui People
The Rapa Nui (Rapa Nui: , Spanish: ) are the Polynesian peoples indigenous to Easter Island. The easternmost Polynesian culture, the descendants of the original people of Easter Island make up about 60% of the current Easter Island population and have a significant portion of their population residing in mainland Chile. They speak both the traditional Rapa Nui language and the primary language of Chile, Spanish. At the 2017 census there were 7,750 island inhabitants—almost all living in the village of Hanga Roa on the sheltered west coast. As of 2011, Rapa Nui's main source of income derived from tourism, which focuses on the giant sculptures called moai. Over the past decade, Rapa Nui activists have been fighting for self-determination and sovereignty over their lands. Protests in 2010 and 2011 by the indigenous Rapa Nui on Easter Island, objecting to the creation of a marine park and reserve, have led to clashes with Chilean police.

Relict Population
In biogeography and paleontology, a relict is a population or taxon of organisms that was more widespread or more diverse in the past. A relictual population is a population currently inhabiting a restricted area whose range was far wider during a previous geologic epoch. Similarly, a relictual taxon is a taxon (e.g. species or other lineage) which is the sole surviving representative of a formerly diverse group. Definition A relict (or relic) plant or animal is a taxon that persists as a remnant of what was once a diverse and widespread population. Relictualism occurs when a widespread habitat or range changes and a small area becomes cut off from the whole. A subset of the population is then confined to the available hospitable area, and survives there while the broader population either shrinks or evolves divergently. This phenomenon differs from endemism in that the range of the population was not always restricted to the local region. In other words, the species or grou ...

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 ...
