São Tomé And Príncipe
São Tomé and Príncipe (; pt, São Tomé e Príncipe (); English: " Saint Thomas and Prince"), officially the Democratic Republic of São Tomé and Príncipe ( pt, República Democrática de São Tomé e Príncipe), is a Portuguese-speaking island country in the Gulf of Guinea, off the western equatorial coast of Central Africa. It consists of two archipelagos around the two main islands of São Tomé and Príncipe, about apart and about off the north-western coast of Gabon.

São Tomé and Príncipe is the second-smallest and second-least populous African sovereign state after Seychelles. The islands were uninhabited until their discovery by Portuguese explorers in the 15th century. Gradually colonized and settled throughout the 16th century, they collectively served as a vital commercial and trade centre for the Atlantic slave trade. The ri ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. According to '' Britannica'', there exists four savanna forms; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in for ...

São Tomé Oriole
The São Tomé oriole (''Oriolus crassirostris''), or great-billed oriole, is a species of bird in the family Oriolidae. The species was named by Gustav Hartlaub in 1857. It is endemic to the island of São Tomé. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. It is threatened by habitat loss. Distribution and habitat It is widely distributed throughout the island of São Tomé, except the northeast (the urban area of São Tomé). It is most abundant in the southwest and on the central massif.

São Tomé Grosbeak
The São Tomé grosbeak (''Crithagra concolor'') is the largest member of the canary genus ''Crithagra'', 50% heavier than the next largest canary species, and possesses a massive bill for a member of that genus. It is endemic to the island of São Tomé. For a long period this bird was known only from three nineteenth-century specimens. It was rediscovered in 1991. The current population is estimated at less than 250, and it is classified as critically endangered by the IUCN. The main threat is habitat destruction. The São Tomé grosbeak was formerly placed in the genus ''Neospiza'' (meaning "new finch") but was assigned to the genus ''Crithagra'' based on a phylogenetic analysis of mitochondrial A mitochondrion (; ) is an organelle found in the cells of most Eukaryotes, such as animals, plants and fungi.

São Tomé Shorttail
The São Tomé shorttail (''Motacilla bocagii''), also known as Bocage's longbill, is a species of passerine bird in the family Motacillidae. It has been classified as the sole member of the genus ''Amaurocichla'', but a 2015 phylogenetic study placed it among the wagtails in the genus ''Motacilla''. It is endemic to the central and southern parts of the island of São Tomé. Its natural habitat is subtropical or tropical moist lowland forests. This species has a small population and is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby ....

São Tomé Ibis
The São Tomé ibis (''Bostrychia bocagei''), also known as the dwarf olive ibis or the dwarf ibis, is endemism, endemic to São Tomé Island, São Tomé off the western coast of Central Africa and exists inside the Gulf of Guinea. Discovered in the 1800s by Francisco Newton, it was once thought to be a subspecies of the larger olive ibis, but is now classified as a distinct species. ''Bostrychia bocagei'' is a critically endangered ibis that measures approximately 2 ft in height. Living with 19 other species of endemic birds on the island, the dwarf ibis is one of 10 that are threatened with extinction. ''B. bocagei'' prefers the southern forests almost exclusively, living there in nests that are high up in the trees to avoid predators. Aside from predation, other common threats to the species include overhunting and habitat loss as a result of overexploitation of resources by the people of São Tomé. Although no specific conservation reforms have been enacted to help ''B. bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
