Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Birds Of The Bismarck Archipelago
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 ...

Myiagra
''Myiagra'' is a genus of passerine birds in the family Monarchidae, the monarch flycatchers, native to Australasia, sometimes referred to as the broad-billed flycatchers or simply broadbills. Taxonomy The genus ''Myiagra'' was introduced in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield. The name combines the Ancient Greek ''muia'' meaning "a fly" and ''agreō'' meaning "to seize". Myiagros was also the name of a Greek god. The type species was designated by George Robert Gray in 1840 as the leaden flycatcher. Species The genus contains 22 species include one that is now extinct: * Oceanic flycatcher (''Myiagra oceanica'') * Palau flycatcher (''Myiagra erythrops'') * † Guam flycatcher (''Myiagra freycineti'') (extinct) * Pohnpei flycatcher (''Myiagra pluto'') * Moluccan flycatcher (''Myiagra galeata'') * Biak black flycatcher (''Myiagra atra'') * Leaden flycatcher (''Myiagra rubecula'') * Steel-blue flycatcher (''Myiagra ferrocyanea'') * Makira flycatcher ('' ...

International Ornithologists' Union
The International Ornithologists' Union, formerly known as the International Ornithological Committee, is a group of about 200 international ornithologists, and is responsible for the International Ornithological Congress and other international ornithological activities, undertaken by its standing committees. International Ornithological Congress The International Ornithological Congress series forms the oldest and largest international series of meetings of ornithologists. It is organised by the International Ornithologists' Union. The first meeting was in 1884; subsequent meetings were irregular until 1926 since when meetings have been held every four years, except for two missed meetings during and in the immediate aftermath of the Second World War.

Mussau Flycatcher
The Mussau flycatcher (''Myiagra hebetior'') is a species of bird in the family Monarchidae. It is endemic to Mussau Island in the Bismarck Archipelago. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forests. Taxonomy and systematics The Mussau flycatcher was originally described in the genus ''Monarcha''. Alternate names include dull flycatcher, dull monarch, Hartert's flycatcher, island flycatcher, lesser shining flycatcher, and little shining flycatcher. The velvet flycatcher (''M. eichorni''), which is found on New Hanover, New Ireland & New Britain, and the Dyaul flycatcher (''M. cervinicolor''), which is endemic to Dyaul Island, were both formerly considered subspecies, but were reclassified as distinct species by the IOC in 2021. The three species were formerly grouped together as the velvet flycatcher under the scientific name ''M. hebetior''. Threats The Mussau flycatcher is threatened by habitat loss ...

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 ...

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] |
New Britain
New Britain ( tpi, Niu Briten) is the largest island in the Bismarck Archipelago, part of the Islands Region of Papua New Guinea. It is separated from New Guinea by a northwest corner of the Solomon Sea (or with an island hop of Umboi the Dampier and Vitiaz Straits) and from New Ireland by St. George's Channel. The main towns of New Britain are Rabaul/Kokopo and Kimbe. The island is roughly the size of Taiwan. While the island was part of German New Guinea, it was named Neupommern ("New Pomerania"). In common with most of the Bismarcks it was largely formed by volcanic processes, and has active volcanoes including Ulawun (highest volcano nationally), Langila, the Garbuna Group, the Sulu Range, and the volcanoes Tavurvur and Vulcan of the Rabaul caldera. A major eruption of Tavurvur in 1994 destroyed the East New Britain provincial capital of Rabaul. Most of the town still lies under metres of ash, and the capital has been moved to nearby Kokopo.
