Karthala White-eye
The Karthala white-eye (''Zosterops mouroniensis''), also known as the Mount Karthala white-eye, Grand Comore white-eye, or Comoro white-eye, is a species of bird in the family Zosteropidae. As suggested by its name, it is endemic to '' Philippia'' heath woodland growing on Mount Karthala on the island of Grand Comore in the Comoros. Mount Karthala is an active volcano and future eruptions pose a serious threat to the Karthala white-eye. The bird is further threatened by human-induced habitat loss. The bird is approximately 13 cm long with olive upperparts and yellow-green underparts. It has a white ring around the eye. Its diet consists of fruits and insect Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs ...s. References External linksBirdLife Species Factsheet Karthala ...

Alphonse Milne-Edwards
Alphonse Milne-Edwards (Paris, 13 October 1835 – Paris, 21 April 1900) was a French mammalogist, ornithologist, and carcinologist. He was English in origin, the son of Henri Milne-Edwards and grandson of Bryan Edwards, a Jamaican planter who settled at Bruges (then in France). Milne-Edwards obtained a medical degree in 1859 and became assistant to his father at the ' in 1876. He became the director of the in 1891, devoting himself especially to fossil birds and deep-sea exploration. In 1881, he undertook a survey of the Gulf of Gascony with Léopold de Folin and worked aboard the ''Travailleur'' and the ''Talisman,'' researching the seas off the Canary Islands, the Cape Verde Islands, and the Azores. For this, he received a gold medal of the Royal Geographical Society. His major ornithological works include ' published in two parts in 1867 and 1872, ' 1866–1874 and ' 1868–1874. His study of fossils led to the discovery of tropical birds such as trogons and parrots from p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Grande Comore
Grande Comore () is an island in Comoros off the coast of Africa. It is the largest island in the Comoros nation. Most of its population is of the Comorian ethnic group. Its population is about 316,600. The island's capital is Moroni, Comoros, Moroni, which is also the national capital. The island is made up of two shield volcanoes, with Mount Karthala being the country's highest point at above sea level.

Endemic Birds Of The Comoros
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] |
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 ...

Insect
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body ( head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruit
In botany, a fruit is the seed-bearing structure in flowering plants that is formed from the ovary after flowering. Fruits are the means by which flowering plants (also known as angiosperms) disseminate their seeds. Edible fruits in particular have long propagated using the movements of humans and animals in a symbiotic relationship that is the means for seed dispersal for the one group and nutrition for the other; in fact, humans and many animals have become dependent on fruits as a source of food. Consequently, fruits account for a substantial fraction of the world's agricultural output, and some (such as the apple and the pomegranate) have acquired extensive cultural and symbolic meanings. In common language usage, "fruit" normally means the seed-associated fleshy structures (or produce) of plants that typically are sweet or sour and edible in the raw state, such as apples, bananas, grapes, lemons, oranges, and strawberries. In botanical usage, the term "fruit" also i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mount Karthala
Mount Karthala or Karthola ( ar, القرطالة ''Al Qirṭālah'') is an active volcano and the highest point of the Comoros at above sea level. It is the southernmost and larger of the two shield volcanoes forming Grande Comore island, the largest island in the nation of Comoros. The Karthala volcano is very active, having erupted more than 20 times since the 19th century. Frequent eruptions have shaped the volcano's 3 km by 4 km summit caldera, but the island has largely escaped broad destruction. Eruptions on April 17, 2005 and May 29, 2006 ended a period of quiet. Volcanic activity April 2005 eruption The eruption, which carried a risk of lava flows and deadly volcanic gas, caused the evacuation of 30,000 residents. The crater was clearly changed by the eruption. A grey field of ash surrounds the crater and the caldera itself seems larger and deeper. The crater lake, which formed after Karthala's last eruption in 1991 and once dominated the caldera, is now go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
