Philip Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an England, English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River (Wisconsin–Minnesota), St. Croix River, cano ...

Manus Island
Manus Island is part of Manus Province in northern Papua New Guinea and is the largest of the Admiralty Islands. It is the fifth-largest island in Papua New Guinea, with an area of , measuring around . Manus Island is covered in rugged jungles which can be broadly described as lowland tropical rain forest. The highest point on Manus Island is Mt. Dremsel, above sea level at the centre of the south coast. Manus Island is volcanic in origin and probably broke through the ocean's surface in the late Miocene, 8 to 10 million years ago. The substrate of the island is either directly volcanic or from uplifted coral limestone. Lorengau, the capital of Manus Province, is located on the island. Momote Airport, the terminal for Manus Province, is located on nearby Los Negros Island. A bridge connects Los Negros Island to Manus Island and the provincial capital of Lorengau. In the 2000 census, the whole Manus Province had a population of 50,321. The Austronesian Manus languages are sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1877
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. Bird ...

Symposiachrus
''Symposiachrus'' is a genus of birds in the family Monarchidae. Most species are endemic to islands in Melanesia but the spectacled monarch is widely distributed and occurs in parts of Indonesia and western Australia. The genus was previously lumped together in the genus ''Monarcha''. Taxonomy and systematics Based on the results of a molecular phylogenetic study published in 2005, the genus ''Monarcha'' was split and 19 species moved to the resurrected genus ''Symposiachrus'' that had been introduced by the French naturalist Charles Lucien Bonaparte in 1854 with the spectacled monarch (''Symposiachrus trivirgatus'') as the type species. The genus name ''Symposiachrus'' combines the Ancient Greek συν/''sun'' meaning "together", ποσις/''posis'' meaning "husband" and αχρως/''akhrōs'' meaning "pallid". The genus ''Symposiachrus'' contains the following twenty–one species: * Black monarch (''Symposiachrus axillaris'') * Spot-winged monarch (''Symposiachrus guttula'' ...

Rambutyo Island
Rambutyo Island (or Rambutso Island) is one of the Admiralty Islands in the Bismarck Archipelago, located at . Politically, Rambutyo Island is part of Manus Province, Papua New Guinea. The population (unknown) is concentrated on the west coast. Villages include Mouklen (pop.500+, close to a defunct plantation) and Lengkau. Geography Rambutyo Island is 88 km2 and is located 50 km SE of Manus Island, part of the Hornos Island Group. It is roughly triangular in shape with a base 16 km in diameter East-West. The centre of the island has a volcanic peak about 230 m high. Offshore lie important reef complexes. The island was surveyed in 1958 by the Royal Australian Survey Corps. The vegetation is moist tropical and subtropical forest, with around 3,000mm of rainfall per year. Logging and coconut groves displaced forest at different times. There are endemic species of rats, bats, birds and a cuscus (Spilocuscus kraemeri, Admiralty Island cuscus) across the Admiralty Isla ...

Ernst Mayr
Ernst Walter Mayr (; 5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned Taxonomy (biology), taxonomist, tropical explorer, ornithologist, Philosophy of biology, philosopher of biology, and History of science, historian of science. His work contributed to the conceptual revolution that led to the Modern synthesis (20th century), modern evolutionary synthesis of Gregor Mendel, Mendelian genetics, systematics, and Charles Darwin, Darwinian evolution, and to the development of the Species, biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the ''species problem''. Ernst Mayr approached the problem with a new definition for species. In his book ''Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of Morphology (biology), morph ...

Monarcha
''Monarcha'' is a genus of bird in the family Monarchidae. They are found in Australia and Melanesia. Taxonomy and systematics The genus ''Monarcha'' was introduced by naturalists Nicholas Vigors and Thomas Horsfield in 1827 with the black-faced monarch (''Monarcha melanopsis'') as the type species. The genus formerly included many more species. Based on the results of a molecular phylogenetic study published in 2005 nineteen species were moved to the resurrected genus '' Symposiachrus'' and three to ''Carterornis''. Extant species The genus ''Monarcha'' contains the following nine species: * Island monarch (''Monarcha cinerascens'') * Black-faced monarch (''Monarcha melanopsis'') * Black-winged monarch (''Monarcha frater'') * Bougainville monarch (''Monarcha erythrostictus'') * Chestnut-bellied monarch (''Monarcha castaneiventris'') * White-capped monarch (''Monarcha richardsii'') * Yap monarch (''Monarcha godeffroyi'') * Tinian monarch (''Monarcha takatsukasae'') ...

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 ...

Forest
A forest is an area of land dominated by trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, '' Global Forest Resources Assessment 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...
