Ogasawara National Park
is a national park in the Ogasawara Islands, located approximately one thousand kilometres to the south of Tokyo, Japan. The park was established in 1972 within the municipality of Ogasawara, itself part of Tokyo. In 2011, the Ogasawara Islands were inscribed upon the UNESCO World Heritage List. Islands The archipelago is also known as the Bonin Islands, a corruption of , meaning 'uninhabited'. The islands were returned to Japanese administration in 1968 after US Occupation. The Chichijima, Hahajima, and Mukojima clusters are included within the park, but of the three Volcano Islands, Iwo Jima and Minami Iwo Jima are not. Flora and fauna According to the IUCN evaluation for UNESCO, 441 taxa of native plants have been recorded, of which 161 of vascular plants and 88 of woody plants are endemic; the only native mammal is the critically endangered Bonin flying fox; of the 195 recorded species of birds, fourteen are on the IUCN Red List; of the two terrestrial reptiles, the O ...

Chichi-jima
is the largest and most populous island in the Japanese archipelago of Bonin or Ogasawara Islands. Chichijima is about north of Iwo Jima. in size, the island is home to about 2,120 people (2021). Connected to the mainland only by a day-long ferry that runs a few times a month, the island is nonetheless organized administratively as the seat of Ogasawara Village in the coterminous Ogasawara Subprefecture of the Tokyo Metropolitan Government. Together with the Volcano and Izu Islands, it makes up Japan's Nanpō Islands. Some Micronesian tools and carvings have been found elsewhere in the Bonins, but Chichijima was long uninhabited when it was rediscovered. Ignored by the Spanish, Dutch, and Japanese Empires for centuries, it was finally claimed by a passing British captain in 1828 and settled by an international group from the Kingdom of Hawaii two years later, the original nucleus of the Ōbeikei ethnic group. Britain subsequently yielded to Japanese claims and co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iwo Jima
is one of the Japanese Volcano Islands, which lie south of the Bonin Islands and together with them make up the Ogasawara Subprefecture, Ogasawara Archipelago. Together with the Izu Islands, they make up Japan's Nanpō Islands. Although south of Tokyo on Honshu, Iwo Jima is administered as part of the Ogasawara Subprefecture of the Tokyo Metropolitan Government. Only in size, the island is still volcanic island, volcanic and emits sulfurous gases. The highest point of Iwo Jima is Mount Suribachi at high. Although likely passed by Micronesians who made their way to the Bonins to the north, Iwo Jima was largely ignored by the Spanish Empire, Spanish, Dutch Empire, Dutch, British Empire, British, and Empire of Japan, Japanese until a relatively late date after its 1543 rediscovery. The Japanese eventually colonized the island, administering it as the Iojima, Tokyo, Ioto or Iojima Village under Tokyo's jurisdiction until all civilians were forcibly evacuated to Honshu in July 1 ...

Hermatypic Coral photosynthetic zooxanthellae, which contribute to their nutritional needs. The term "hermatypic" is sometimes misused, being assumed to apply to all zooxanthellate corals. However, there are zooxanthe ...
Hermatypic corals are those corals in the order Scleractinia which build reefs by depositing hard calcareous material for their skeletons, forming the stony framework of the reef. Corals that do not contribute to coral reef development are referred to as ahermatypic (non-reef-building) species. Many reef-forming corals contain symbiotic Symbiosis (Ancient Greek : living with, companionship < : together; and ''bíōsis'': living) is any type of a close and long-term biolo ...

Cetacea
Cetacea (; , ) is an infraorder of aquatic mammals belonging to the order Artiodactyla that includes whales, dolphins and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movements of their tail, which ends in a paddle-like fluke, using their flipper-shaped forelimbs to steer. While the majority of cetaceans live in marine environments, a small number reside solely in brackish water, brackish or fresh water. Having a cosmopolitan distribution, they can be found in some rivers and all of Earth's oceans, and many species migrate throughout vast ranges with the changing of the seasons. Cetaceans are famous for cetacean intelligence, their high intelligence, complex social behaviour, and the enormous size of some of the group's members. For example, the blue whale reaches a maximum confirmed length of and a weight of 173 tonne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Bonin Flying Fox
The Bonin flying fox (''Pteropus pselaphon''), also known as Bonin fruit bat, is a species of flying fox in the family Pteropodidae. It is endemic to four islands (Chichijima, Hahajima, North Iwo Jima, and South Iwo Jima) of the Bonin Islands group, Japan. Its natural habitat is subtropical forests. It is threatened by habitat loss. Etymology The Bonin flying fox was described by British naturalist George Tradescant Lay in 1829. He gave it the species name ''pselaphon'' as a reference to "the habit of feeling instead of seeing its way in the day time." ''Pselaphon'' is a Neo-Latin word ."Pselaphus." Merriam-Webster.com. Merriam-Webster, n.d. Web. 3 September 2017. Taxonomy As the Pteropus genus is quite speciose, it is traditionally divided into closely related species groups, identified based on morphology. Traditionally, the Bonin flying fox has been the identifier of the ''pselaphon'' species group, of which there are several other members: *the extinct large Palau f ...

Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Woody Plants
A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem. In cold climates, woody plants further survive winter or dry season above ground, as opposed to herbaceous plants that die back to the ground until spring. Characteristics Woody plants are usually trees, shrubs, or lianas. These are usually perennial plants whose stems and larger roots are reinforced with wood produced from secondary xylem. The main stem, larger branches, and roots of these plants are usually covered by a layer of bark. Wood is a structural tissue that allows woody plants to grow from above ground stems year after year, thus making some woody plants the largest and tallest terrestrial plants. Woody plants, like herbaceous perennials, typically have a dormant period of the year when growth does not take place. This occurs in temperate and continental due to freezing temperatures and lack of daylight during the winter months. Meanwhile, dormancy in subtropical an ...

Vascular Plant
Vascular plants (), also called tracheophytes (, ) or collectively tracheophyta (; ), are plants that have lignin, lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified Tissue (biology), tissue (the phloem) to conduct products of photosynthesis. The group includes most embryophyte, land plants ( accepted known species) excluding mosses. Vascular plants include the clubmosses, Equisetum, horsetails, ferns, gymnosperms (including conifers), and angiosperms (flowering plants). They are contrasted with nonvascular plants such as mosses and green algae. Scientific names for the vascular plants group include Tracheophyta, Tracheobionta and Equisetopsida sensu lato, Equisetopsida ''sensu lato''. Some early land plants (the rhyniophytes) had less developed vascular tissue; the term eutracheophyte has been used for all other vascular plants, including all living ones. Historically, vascular plants were known as "hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Native Plant
In biogeography, a native species is indigenous to a given region or ecosystem if its presence in that region is the result of only local natural evolution (though often popularised as "with no human intervention") during history. The term is equivalent to the concept of indigenous or autochthonous species. A wild organism (as opposed to a domesticated organism) is known as an introduced species within the regions where it was anthropogenically introduced. If an introduced species causes substantial ecological, environmental, and/or economic damage, it may be regarded more specifically as an invasive species. A native species in a location is not necessarily also endemic to that location. Endemic species are ''exclusively'' found in a particular place. A native species may occur in areas other than the one under consideration. The terms endemic and native also do not imply that an organism necessarily first originated or evolved where it is currently found. Notion The notion ...
