Camiguin Hawk-owl
The Camiguin boobook or Camiguin hawk-owl (''Ninox leventisi'') is an owl species resident to the Camiguin island in the Philippines. It is the only owl in the country with greenish-yellow or grayish eyes. It was previously known as a subspecies of the Philippine hawk-owl, but was reclassified in 2012, as voice and other evidence suggested it a distinct species. Its native name is ''kugkug'' Description EBird describes the bird as "A rare medium-sized owl of remnant broadleaf forest on Camiguin Island. Uniformly barred, with a brown head and upperparts, a pale bar behind the shoulder, warmer brown underparts, long whiskers around the face, and pale yellow eyes. Note the white throat patch. Song is a rapid series of fairly low 'woop' notes, sometimes given in duet. White throat particularly noticeable when calling." Among the species complex, this owl is unique in that its eyes are striking greenish-yellow versus the standard yellow or reddish-brown eyes of the rest of its re ...

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups within th ...

Forest Edge
A woodland edge or forest edge is the transition zone (ecotone) from an area of woodland or forest to fields or other open spaces. Certain species of plants and animals are adapted to the forest edge, and these species are often more familiar to humans than species only found deeper within forests. A classic example of a forest edge species is the white-tailed deer in North America. The woodland edge on maps On topographic maps woods and forests are generally depicted in a soft green colour. Their edges are – like other features – usually determined from aerial photographs, but sometimes also by terrestrial survey. However, they only represent a snapshot in time because almost all woods have a tendency to spread or to gradually fill clearings. In addition, working out the exact edge of the wood or forest may be difficult where it transitions into scrub or bushes or the trees thin out slowly. Differences of opinion here often involved several tens of metres. In addition, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Philip Godfrey Cosep Jakosalem
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 2012
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 common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings 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 furthe ...

Fauna Of Camiguin
Fauna (: faunae or faunas) is all of the animal life present in a particular region or time. The corresponding terms for plants and fungi are ''flora'' and ''funga'', respectively. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Modern Greek equivalent of fauna (πανίς or rather πανίδα). ''Fauna'' is also the word for a book ...

Endemic Birds Of The Philippines
This article is one of a series providing information about endemism among birds in the world's various zoogeographic zones. Patterns of endemism The Wild Bird Club of the Philippines has a checklist of the birds of the Philippines which follows the IOC World Bird List. Of these 260 bird species endemic to the Philippines. Many of these are restricted to specific islands, particularly Luzon, Mindanao, and Palawan.''A Guide to the Birds of the Philippines'', Robert S. Kennedy et al., Oxford University Press, 2013. The number of endemic species recognized in the Philippines has increased in recent years, mainly due to " splits" of species and, to a much lesser extent, due to the discovery of previously unknown species. An example of splitting is the division of the erstwhile species Philippine hawk-owl (''Ninox scutulata'') into seven species, now called by the name of this-or-that boobook (Luzon boobook, Mindoro boobook, etc. see the list below). Another example is the split of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ninox
''Ninox'' is a genus of true owls comprising 36 species found in Asia and Australasia. Many species are known as hawk-owls or boobooks, but the northern hawk-owl (''Surnia ulula'') is not a member of this genus. Taxonomy The genus was introduced by English naturalist Brian Houghton Hodgson in 1837 with the type species as ''Ninox nipalensis'', a junior synonym of ''Strix lugubris'' Tickell 1833. ''Strix lugubris'' is now considered a subspecies of the brown boobook (''Ninox scutula lugubris''). Species The genus contains 37 species: *† Laughing owl, ''Ninox albifacies'' (extinct) * Rufous owl, ''Ninox rufa'' * Powerful owl, ''Ninox strenua'' * Barking owl, ''Ninox connivens'' * Sumba boobook, ''Ninox rudolfi'' * Australian boobook, ''Ninox boobook'' * Rote boobook ''Ninox rotiensis'' * Timor boobook ''Ninox fusca'' * Alor boobook, ''Ninox plesseni'' * Tasmanian boobook, ''Ninox leucopsis'' * Morepork, ''Ninox novaeseelandiae'' * Northern boobook, ''Ninox japonica ...

Slash-and-burn
Slash-and-burn agriculture is a form of shifting cultivation that involves the cutting and burning of plants in a forest or woodland to create a Field (agriculture), field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the Biomass (ecology), biomass is burned, resulting in a nutrient-rich layer of ash which makes the Soil fertility, soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the Resource extraction, extraction of valuable geological materials and minerals from the surface of the Earth. Mining is required to obtain most materials that cannot be grown through agriculture, agricultural processes, or feasibly created Chemical synthesis, artificially in a laboratory or factory. Ores recovered by mining include Metal#Extraction, metals, coal, oil shale, gemstones, limestone, chalk mining, chalk, dimension stone, rock salt, potash, gravel, and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even fossil water, water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, and final mine reclamation, reclamation or restoration of the land after the mine is closed.
