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.

Wilhelm Blasius
August Wilhelm Heinrich Blasius (5 July 1845 in Braunschweig – 31 May 1912 in Braunschweig) was a German ornithologist. Blasius belonged to a family of scientists: his father was the ornithologist Johann Heinrich Blasius (1809-1870) and his brother was the ornithologist Rudolf Heinrich Paul Blasius (1842-1907). In 1871 he became a professor of zoology and botany at the Braunschweig University of Technology. He also served as director of its Naturhistorisches Museum (Braunschweig), natural history museum and Botanischer Garten der Technischen Universität Braunschweig, botanical gardens. He was a member of the council for the ''Deutsche Ornithologen-Gesellschaft'' (German Ornithological Society).

Black-crowned White-eye
The black-crowned white-eye (''Zosterops atrifrons'') is a songbird species. It is closely related to the Old World babblers, and its family Zosteropidae might better be included in the Tiimalidae. Its subspecies from the Sulawesi region might warrant recognition as distinct species ''Z. subatrifrons''. The Sangihe white-eye (''Z. nehrkorni'') and the Seram white-eye (''Z. stalkeri'') were formerly included in ''Z. atrifrons'', as is still, on occasion, the black-fronted white-eye (''Z. minor''). It is endemic to Indonesia. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. Quite common, it is not considered a threatened species Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of '' critical depen ... by the IUCN. Gallery Fil ...

Birds Described In 1888
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Birds Of Sangihe
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zosterops
''Zosterops'' (meaning "eye-girdle") is a genus of passerine birds containing the typical white-eyes in the white-eye family Zosteropidae. The genus has the largest number of species in the white-eye family. They occur in the Afrotropical, Indomalayan, and Australasian realms. Typical white-eyes have a length of between . Their most characteristic feature is a conspicuous white feather ring around the eye, though some species lack it. The species in this group vary in the structural adaptations of the tongue. The ''Zosterops'' 'griseotinctus''group is an example of a "great speciator" inhabiting a vast area and showing a remarkable morphological differentiation on islands, some of which maybe as close as apart. Systematics The genus ''Zosterops'' was introduced by the naturalists Nicholas Vigors and Thomas Horsfield in 1827. The name combines the Ancient Greek words ''zōstēros'' "belt" or "girdle" and ''ōpos'' "eye". The type species was designated as the Malagasy white-ey ...

Seram White-eye
The Seram white-eye (''Zosterops stalkeri'') is a small passerine bird in the white-eye family. It is an endemic resident breeder in open woodland in Seram, Indonesia. It was formerly considered conspecific with black-fronted white-eye, ''Zosterops minor'', 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 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 ..., ''Zosterops nehrkorni''. Compared to related taxa, the bill of Seram white-eye is paler, deeper, and broader at the base. Its eye-ring is narrow and broken at the front. The crown and sides of the head are black and the upperparts are dark bronze. The rump is a distinctive yellow-bronze. The sides of the breast ...

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 reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Montane Forest
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
