Ogasawara Subtropical Moist Forests
The Ogasawara subtropical moist forests is a terrestrial ecoregion which encompasses the Ogasawara Archipelago of Japan. The Ogasawara Archipelago lies in the Pacific Ocean south of Honshu, Japan's largest island, and north of the Marianas Islands. The ecoregion includes the Bonin Islands and Volcano Islands chains. The islands are volcanic in origin, and have never been linked to a continent. They are home to distinct plants and animals including many endemic species. The islands also constitute a distinct freshwater ecoregion (Ogasarawa Islands - Kazan Archipelago). Geography The Bonin Islands are about 1000 km south of Honshu, Japan's largest island, and north of the Tropic of Cancer. The Bonin islands form three clusters, Mukojima, Chichijima, and Hahajima, composed of one larger island and several smaller ones. Chichishima, the largest island, and Hahajima, the second-largest, are the only inhabited Bonin islands. The highest point on Hahajima is 326 m, and Chichishima's h ...

Ogasawara Archipelago
The Bonin Islands, also known as the , are an archipelago of over 30 subtropical and tropical islands, some directly south of Tokyo, Japan and northwest of Guam. The name "Bonin Islands" comes from the Japanese word ''bunin'' (an archaic reading of ''mujin''), meaning "no people" or "list of uninhabited regions, uninhabited". The only inhabited islands of the group are Chichijima (), the seat of the municipal government, and Hahajima (). Archeological evidence has revealed that some of the islands may have been prehistorically inhabited by members of an unknown Micronesian ethnicity. Ogasawara, Tokyo, Ogasawara Municipality (''mura'') and Ogasawara Subprefecture take their names from the Ogasawara Group. The is also used as a wider collective term that includes other islands in Ogasawara Municipality, such as the Volcano Islands, along with three other remote islands (Nishinoshima (Ogasawara), Nishinoshima, Minamitorishima, and Okinotorishima).

Nishinoshima (Ogasawara)
is a volcanic island located around south-southeast of Tokyo, that is part of the Volcano Islands arc. Originally, the above-water part of the ridge of an underwater caldera, Nishinoshima was enlarged in 1974 after fresh eruptions created a new section of the island. Another eruption that began in November 2013 further enlarged the island and attracted worldwide attention. A volcanic cone soon formed, rising to an estimated height of by July 2016. The eruptions ceased by November 2015, though emissions of volcanic gases continued for several months afterwards. As of 2016, the island was about in size and showed evidence of the return of various plants and animal species. There were further eruptions in 2017, 2018, and in 2019-2020. As of 14 August 2020, it is about and over in diameter. Etymology The island was named "Rosario Island" when it was discovered by the Spanish ship ''Rosario'' in 1702. That was the island's name until 1904 when the Japanese term "Nishinoshim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesic Habitat
In ecology, a mesic habitat is a type of habitat with a moderate or well-balanced supply of moisture, e.g., a mesic forest, a temperate hardwood forest, or dry-mesic prairie. Mesic habitats transition to xeric shrublands Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (ancient Greek xērós, “dry") shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this ... in a non-linear fashion, which is evidence of a threshold. Mesic is one of a triad of terms used to describe the amount of water in a habitat. The others are xeric and hydric. Further examples of mesic habitats include streamsides, wet meadows, springs, seeps, irrigated fields, and high elevation habitats. These habitats effectively provide drought insurance as land at higher elevations warms due to seasonal or other change. Healthy mesic habitats act like sponges in that they store water in such a way that it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The leaves are arranged alternately, simple (strictly compound with only one leaflet) with a swelling where the petiole meets the lamina, often have toothed edges, usually have prominent veins and often turn red before falling. The flowers are usually arranged in a raceme, usually bisexual, have four or five sepals and petals and many stamens. The petals usually have finely-divided, linear lobes.

Micronesia
Micronesia (, ) is a subregion of Oceania, consisting of about 2,000 small islands in the western Pacific Ocean. It has a close shared cultural history with three other island regions: the Philippines to the west, Polynesia to the east, and Melanesia to the south—as well as with the wider community of Austronesian peoples. The region has a tropical marine climate and is part of the Oceanian realm. It includes four main archipelagos—the Caroline Islands, the Gilbert Islands, the Mariana Islands, and the Marshall Islands—as well as numerous islands that are not part of any archipelago. Political control of areas within Micronesia varies depending on the island, and is distributed among six sovereign nations. Some of the Caroline Islands are part of the Republic of Palau and some are part of the Federated States of Micronesia (often shortened to "FSM" or "Micronesia"—not to be confused with the identical name for the overall region). The Gilbert Islands (along with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metrosideros
''Metrosideros'' is a genus of approximately 60 trees, shrubs, and vines mostly found in the Pacific region in the family Myrtaceae. Most of the tree forms are small, but some are exceptionally large, the New Zealand species in particular. The name derives from the Ancient Greek ''metra'' or " heartwood" and ''sideron'' or "iron". Perhaps the best-known species are the pōhutukawa (''M. excelsa''), northern (''M. robusta'') and southern rātā (''M. umbellata'') of New Zealand, and '' ōhia lehua'' (''M. polymorpha''), from the Hawaiian Islands. Distribution ''Metrosideros'' is one of the most widely spread flowering plant genera in the Pacific. New Caledonia has 21 species of ''Metrosideros'', New Zealand has 12, New Guinea has seven and Hawaii has 5. The genus is present on most other high Pacific Islands, including Solomon Islands, Vanuatu, Fiji, Samoa, Cook islands, French Polynesia, Bonin Islands and Lord Howe Island, but absent from Micronesia .

''M. boninensis'' is classified as ‘endangered’ in the Japanese Red Data Book and, although there were 326 plants recorded in 2004, genetic diversity of ''M. boninensis'' is extremely low. Taxonomy The species was first formally described by botanist Bunzo Hayata in 1918, as ''Eugenia boninensis''. This was corrected to ''M. boninensis'' in 1938 by Takasi Tuyama. Cultivars There are no known cultivars of ''M. boninensis'' available, and the plant is not widely available in pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
