Sangihe Island
Sangir Besar, commonly called Sangir Island (with the spelling variants "Sangihe", "Sanghir" or "Sangi"), is an island in the Sangir Islands group. Its Indonesian name literally means "Great Sangir", in reference to the fact that it is the archipelago's main island. It is part of the North Sulawesi province. The main language is the Sangir language. It was the scene of the violent eruption of Gunung Awu volcano on 2 March 1856. The existing mountain was reshaped by the eruption, and flooding was extensive. The death toll was estimated to exceed two thousand, possibly as high as 6,000. Other major eruptions occurred in 1966 and 2004. The critically endangered cerulean flycatcher and Sangihe whistler The Sangihe whistler or Sangihe shrikethrush (''Coracornis sanghirensis'') is a species of bird in the family Pachycephalidae.

Extinct Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Indonesia
Indonesia, officially the Republic of Indonesia, is a country in Southeast Asia and Oceania between the Indian and Pacific oceans. It consists of over 17,000 islands, including Sumatra, Java, Sulawesi, and parts of Borneo and New Guinea. Indonesia is the world's largest archipelagic state and the 14th-largest country by area, at . With over 275 million people, Indonesia is the world's fourth-most populous country and the most populous Muslim-majority country. Java, the world's most populous island, is home to more than half of the country's population. Indonesia is a presidential republic with an elected legislature. It has 38 provinces, of which nine have special status. The country's capital, Jakarta, is the world's second-most populous urban area. Indonesia shares land borders with Papua New Guinea, East Timor, and the eastern part of Malaysia, as well as maritime borders with Singapore, Vietnam, Thailand, the Philippines, Australia, Palau, and India ...

Biodiversity
Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic (''genetic variability''), species (''species diversity''), and ecosystem (''ecosystem diversity'') level. Biodiversity is not distributed evenly on Earth; it is usually greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than 10% of earth's surface and contain about 90% of the world's species. Marine biodiversity is usually higher along coasts in the Western Pacific, where sea surface temperature is highest, and in the mid-latitudinal band in all oceans. There are latitudinal gradients in species diversity. Biodiversity generally tends to cluster in hotspots, and has been increasing through time, but will be likely to slow in the future as a primary result of deforestation. It encompasses the evolutionary, ecological, and cultural ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wallacea
Wallacea is a biogeographical designation for a group of mainly Indonesian islands separated by deep-water straits from the Asian and Australian continental shelves. Wallacea includes Sulawesi, the largest island in the group, as well as Lombok, Sumbawa, Flores, Sumba, Timor, Halmahera, Buru, Seram, and many smaller islands. The islands of Wallacea lie between the Sunda Shelf (the Malay Peninsula, Sumatra, Borneo, Java, and Bali) to the west, and the Sahul Shelf including Australia and New Guinea to the south and east. The total land area of Wallacea is . Geography Wallacea is defined as the series of islands stretching between the two continental shelves of Sunda and Sahul, but excluding the Philippines. Its eastern border (separating Wallacea from Sahul) is represented by a zoogeographical boundary known as Lydekker's Line, while the Wallace Line (separating Wallacea from Sunda) defines its western border. The Weber Line is the midpoint, at which Asian and Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism In Birds
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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerulean Flycatcher
The cerulean flycatcher (''Eutrichomyias rowleyi'') is a medium-sized (up to 18 cm long), blue passerine with bright cerulean blue plumage, a bare white orbital ring, dark brown iris, bluish black bill and pale blue-grey below. The young has a shorter tail and grey underparts. It is the only member of the monotypic genus ''Eutrichomyias''. Although it resembles a monarch flycatcher, it is actually related to the fantails. Taxonomy and systematics The scientific name commemorates the British explorer and ornithologist George Dawson Rowley. The cerulean flycatcher was originally described in the genus '' Zeocephus'', and until recently was known as the cerulean paradise-flycatcher. Alternate names include Rowley's flycatcher and Rowley's paradise-flycatcher. Although initially classified in Monarchidae, a 2017 study involving sequencing of DNA from the type specimen found that it was a member of the fantail family Rhipiduridae, being classified in the basal subfamily Lamprol ...

Sangihe White-eye
The Sangihe white-eye (''Zosterops nehrkorni'') is a species of bird in the white-eye family. It is Endemism, endemic to Sangir Island, Sangihe, Indonesia. Its natural habitat is subtropical or tropical moist montane forests. It is threatened by habitat loss. It was formerly considered conspecific with black-crowned white-eye (''Zosterops atrifrons''), but work by Pamela C. Rasmussen and her colleagues showed that it is a separate species. The same research also confirmed the specific status of the Seram white-eye, ''Zosterops stalkeri''. References * P. C. Rasmussen, J. C. Wardill, F. R. Lambert and J.
