Micronesian Imperial Pigeon
The Micronesian imperial pigeon (''Ducula oceanica''), also known as the Micronesian pigeon, and Belochel is a species of bird in the family Columbidae (doves). It is found in Palau, the Caroline Islands, the Marshall Islands and Nauru. Its habitats include montane forests, secondary forests, forests on beaches, and mangroves. It is threatened by hunting and deforestation, and the IUCN has assessed it as a near-threatened species. Taxonomy The species was first described as ''Columba oceanica'' in 1826. The binomial authority was formerly considered to be Lesson & Garnot, but it is now given as Desmarest. Five subspecies are recognized: ''D. o. monacha'' in Palau and Yap, ''D. o. teraokai'' on Chuuk, ''D. o. townsendi'' on Pohnpei, ''D. o. oceanica'' on Kosrae, and ''D. o. ratakensis'' in the Marshall Islands. Description The Micronesian imperial pigeon is about long and weighs . The head and neck are ashy grey. The back and wing coverts are dark green, reflecting dark blue. ...

Anselme Gaëtan Desmarest
Anselme Gaëtan Desmarest (6 March 1784 – 4 June 1838) was a French Zoology, zoologist and author. He was the son of Nicolas Desmarest and the father of Eugène Anselme Sébastien Léon Desmarest. Career Desmarest was a disciple of Georges Cuvier and Alexandre Brongniart, and in 1815, he succeeded Pierre André Latreille to the professorship of zoology at the '. He was elected to the American Philosophical Society in 1819 and to the Académie Nationale de Médecine in 1820. Publications Desmarest published ' (1805), ' (1825), ' (1820), and ' (1816–30, with André Marie Constant Duméril). His ''Mammalogie'' was significant as it contained a comprehensive list of all mammals known at the time, including living forms and extinct forms known only from fossils. Desmarest was one of the first scientists to routinely apply both genus and species names to animals. Prior to his time, it was common practice to give only a genus name to a new animal.

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of Micronesia
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 further ...

Ducula
''Ducula'' is a genus of the pigeon family Columbidae, collectively known as imperial pigeons. They are large to very large pigeons with a heavy build and medium to long tails. They are arboreal, feed mainly on fruit and are closely related to the other genus of fruit-eating doves, ''Ptilinopus''. Both genera display brightly coloured plumage, predominantly green, often with contrasting under-parts of purple, orange or red. Some ''Ducula'' have prominently swollen ceres. They have large gapes and swallow seeds whole, playing an important role in seed dispersal. Imperial pigeons are found in forests of southern Asia, New Guinea, northern Australia and the Pacific islands. Many species are nomadic, travelling long distances to exploit seasonal fruit sources. Some undertake migrations and all are strong fliers. Because of habitat loss and predation, species of ''Ducula'' are amongst the most threatened of avian species globally. Taxonomy The genus ''Ducula'' was introduced in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. In 2012 there were 5,196 animals and 6,789 plants classified as vulnerable, compared with 2,815 and 3,222, respectively, in 1998. 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 taxon ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Majuro Atoll
Majuro (; Marshallese: ' ) is the capital and largest city of the Marshall Islands. It is also a large coral atoll of 64 islands in the Pacific Ocean. It forms a legislative district of the Ratak (Sunrise) Chain of the Marshall Islands. The atoll has a land area of and encloses a lagoon of . As with other atolls in the Marshall Islands, Majuro consists of narrow land masses. It has a tropical trade wind climate, with an average temperature of . Majuro has been inhabited by humans for at least 2,000 years and was first settled by the Austronesian ancestors of the modern day Marshallese people. Majuro was the site of a Protestant mission and several copra trading stations in the 1870s, before the German Empire annexed the atoll as part of the German Protectorate of the Marshall Islands in 1885. The city was later under Japanese and American administration. After the Marshall Islands broke away from the Federated States of Micronesia in 1978 to form the Republic of the Marshall ...

Ornithological Society Of New Zealand
The Ornithological Society of New Zealand (OSNZ), also known as Birds New Zealand, is a non-profit organisation dedicated to the study of birds and their habitats in the New Zealand region. Founded in 1940, it caters to a wide variety of people interested in the birds of the region, from professional ornithologists to casual birdwatchers. The Society publishes a quarterly peer-reviewed scientific journal, ''Notornis'', and a quarterly news magazine, ''Birds New Zealand'' (formerly ''Southern Bird''). It also organises membership-based scientific projects, such as the Atlas of Bird Distribution in New Zealand. History Following preliminary discussions in 1938 and 1939, the Society was formally established at an inaugural general meeting chaired by Robert Falla at Canterbury Museum on 24 May 1940. It became an incorporated body in January 1953.Gill, B.J.; & Heather, B.D. (1990). ''A Flying Start. Commemorating 50 years of the Ornithological Society of New Zealand, 1940–1990'' ...

Angaur
, or in Palauan, is an island and state in the Island country, island nation of Palau. History Angaur was traditionally divided among some eight clans. Traditional features within clan areas represent important symbols giving identity to families, clans and regions . These features include a variety of stone platforms with historical and traditional importance. Traditional cemeteries are frequently located in or around some of these stone platforms. The large quantities of shell recovered from archaeological sites gives evidence for an intensive exploitation of the limited lagoon surrounding the island and for collecting and fishing outside of the reef as well. On the island, the localized areas of soil were intensively used for garden plots. The first sighting of Angaur, Babeldaob, Koror, and Peleliu recorded by Westerners was by the Spanish expedition of Ruy López de Villalobos at the end of January 1543. They were then charted as ''Los Arrecifes'' (The Reefs in Spanish). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peleliu
Peleliu (or Beliliou) is an island in the island nation of Palau. Peleliu, along with two small islands to its northeast, forms one of the sixteen states of Palau. The island is notable as the location of the Battle of Peleliu in World War II. History Peleliu was traditionally divided into five villages. Teliu is located on the southwest coast bordered on the north by Ngerkeiukl on the west coast, Ngesias in the central portion of the island, and Ngerdelolk on the east coast. Ngerchol occupies the northern part of the island on the west side of Bloody Nose Ridge. Most of the surface remains of the traditional villages have been obliterated. However, the locations of the villages and the locations of features within the villages, including odesongel, are known and preserved in the oral tradition. These traditional features are important symbols giving identity to families, clans and regions. The lagoon and adjacent rock islands are important resource areas, and probably were int ...

Rock Islands
The Rock Islands of Palau, also called ''Chelbacheb'', are a collection of several hundred small limestone or coral uprises in the Southern Lagoon of Palau between Koror and Peleliu, now an incorporated part of Koror State. There are between 250 and 300 islands in the group according to different sources, with an aggregate area of and a maximum height of . The islands were declared a UNESCO World Heritage Site in 2012. History Before European contact, the islands were inhabited by the indigenous Palauan people. The Rock Islands, with their steep cliffs and protected lagoons, were used for fishing, agriculture and as places for spiritual practices. Palau's early settlers were believed to have arrived from Southeast Asia or the Philippines around 1000 BCE. The first recorded European contact with the Rock Islands came in 1543, when Spanish explorer Ruy López de Villalobos passed through the region. However, it was not until the late 19th century that the islands became mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
