Palawan Hornbill
The Palawan hornbill (''Anthracoceros marchei'') is a large forest bird endemic to the Philippines. It is one of the 11 endemic hornbills in the country. It is only found in Palawan and nearby islands of Balabac, Busuanga, Calauit, Culion and Coron. It is locally known as 'talusi' in the language Cuyunon, It is threatened by habitat loss, hunting and trapping for the cage-bird trade. Description and Behavior It's described as large bird (approximately long, weighing , more than 92% of bird species) of lowland and foothill forest on Palawan and neighbouring islands. Its plumage is entirely black except for a white tail and a long, thick, pale cream-colored bill and casque. Whitish bare skin around the eyes and across the throat is tinged blue. Female has a smaller bill and casque. Unmistakable. The only hornbill in its range. Voice is a raucous cackling which can be transcribed as ''kaaww'' and ''kreik-kreik''." They exhibit sexual dimorphism in which males have more promine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Émile Oustalet
Jean-Frédéric Émile Oustalet (24 August 1844 – 23 October 1905 Saint-Cast) was a French zoologist.Hellmayr CE (1906). "Emile Oustalet bituary. ''Ornithologische Monatsberichte'' 14 (4): 57-59Scan Oustalet was born at Montbéliard, in the department of Doubs. He studied at the Ecole des Hautes-Etudes and his first scientific work was on the respiratory organs of dragonfly larvae. He was employed at the Muséum National d'Histoire Naturelle, where he succeeded Jules Verreaux as assistant-naturalist in 1873. In 1900 he succeeded Alphonse Milne-Edwards as Professor of Mammalogy. French ornithologist Émile Oustalet described a specimen from Branco as a separate species ''Passer brancoensis'' in 1883, which was recognised as the subspecies ''Passer iagoensis brancoensis'' by W. R. P. Bourne, who claimed to observe differences between Iago sparrows from different islands. He co-authored ''Les Oiseaux de la Chine'' (1877) with Armand David, and also wrote ''Les Oiseaux du Cambodg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangrove Swamp
Mangrove forests, also called mangrove swamps, mangrove thickets or mangals, are productive wetlands that occur in coastal intertidal zones. Mangrove forests grow mainly at tropical and subtropical latitudes because mangroves cannot withstand freezing temperatures. There are about 80 different species of mangroves, all of which grow in areas with low-oxygen soil, where slow-moving waters allow fine sediments to accumulate.What is a mangrove forest? National Ocean Service, NOAA. Updated: 25 March 2021. Retrieved: 4 October 2021. Many mangrove forests can be recognised by their dense tangle of prop roots that make the trees appear to be standing on stilts above the water. This tangle of roots allows the trees to handle the daily rise and fall of tides, which means that most mangroves get flooded at least twice per day. ...

Birds Of Palawan
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. Birds ...

Anthracoceros
''Anthracoceros'' is a genus of birds in the family Bucerotidae. The genus was introduced by the German naturalist Ludwig Reichenbach in 1849. The type species was subsequently designated as the Malabar pied hornbill (''Anthracoceros coronatus''). The name is a combination of the Ancient Greek words ανθραξ ''anthrax'', ανθρακος ''anthrakos'' meaning "coal black" and κερας ''keras'', κερως ''kerōs'' meaning "horn". A molecular phylogenetic study published in 2013 found that ''Anthracoceros'' was sister to the genus ''Ocyceros ''Ocyceros'' is a genus of birds in the family Bucerotidae.

Iwahig Prison And Penal Farm
Iwahig Prison and Penal Farm in Puerto Princesa City, Palawan, Philippines is one of seven operating units of the Bureau of Corrections under the Department of Justice. History American territorial period The Spanish regime had earlier designated Puerto Princesa, Palawan as a place where offenders sentenced to banishment were exiled, often as a death sentence due to the endemic malaria. Yet, the facility was established only during the American occupation. Governor Luke Wright authorized the establishment of a penal colony in the province of Palawan on November 16, 1904. This penal settlement, which originally comprised an area of 22 acres, served as a depository for prisoners who could not be accommodated at the Bilibid Prison in Manila. A prison facility was created by the American military in the rain forest of Puerto Princesa. Lieutenant George Wolfe, a member of the U.S. expeditionary force was the prison's first superintendent.

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

They also found a cave dome measuring above the undergr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mining
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit. The exploitation of these deposits for raw material is based on the economic viability of investing in the equipment, labor, and energy required to extract, refine and transport the materials found at the mine to manufacturers who can use the material. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water. Modern mining processes involve prospecting for ore bodies, analysis of the profit potential of a proposed mine, extraction of the desired materials, an ...

Habitat Destruction
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 ...

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Primary Forest
An old-growth forestalso termed primary forest, virgin forest, late seral forest, primeval forest, or first-growth forestis a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features, and might be classified as a climax community. The Food and Agriculture Organization of the United Nations defines primary forests as naturally regenerated forests of native tree species where there are no clearly visible indications of human activity and the ecological processes are not significantly disturbed. More than one-third (34 percent) of the world's forests are primary forests. Old-growth features include diverse tree-related structures that provide diverse wildlife habitat that increases the biodiversity of the forested ecosystem. Virgin or first-growth forests are old-growth forests that have never been logged. The concept of diverse tree structure includes multi-layered canopies and canopy gaps, greatly varying tree height ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
