Sylviornis Neocaledoniae
''Sylviornis'', also known by its native name of Du, is an extinct genus of large, flightless bird that was endemic to the islands of New Caledonia in the Western Pacific. It is considered to constitute one of two genera in the extinct family Sylviornithidae, alongside '' Megavitiornis'' from Fiji, which are related to the Galliformes, the group containing the turkeys, chickens, quails and pheasants. ''Sylviornis'' was never encountered alive by scientists, but it is known from many thousands of subfossil bones found in deposits, some of them from the Holocene, on New Caledonia and the adjacent Île des Pins. It was likely hunted to extinction shortly after the first human arrival to New Caledonia around 1500 BC. Description ''Sylviornis'' was a huge flightless bird, standing up to tall, and weighing around on average. In the 2016 study, its height in resting stance was estimated up to , while its mass estimate decreased to . It is the most massive galliform known to h ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Island Gigantism
Island gigantism, or insular gigantism, is a biological phenomenon in which the size of an animal species isolated on an island increases dramatically in comparison to its mainland relatives. Island gigantism is one aspect of the more general "island effect" or "Foster's rule", which posits that when mainland animals colonize islands, small species tend to evolve larger bodies, and large species tend to evolve smaller bodies (insular dwarfism). This is itself one aspect of the more general phenomenon of island syndrome which describes the differences in morphology, ecology, physiology and behaviour of insular species compared to their continental counterparts. Following the arrival of humans and associated introduced predators (dogs, cats, rats, pigs), many giant as well as other island endemics have become extinct. A similar size increase, as well as increased woodiness, has been observed in some insular plants. Possible causes Large mammalian carnivores are often absent on isl ...

Holocene Extinction
The Holocene extinction, or Anthropocene extinction, is the ongoing extinction event during the Holocene epoch. The extinctions span numerous families of bacteria, fungi, plants, and animals, including mammals, birds, reptiles, amphibians, fish, invertebrates, and affecting not just terrestrial species but also large sectors of marine life. With widespread degradation of biodiversity hotspots, such as coral reefs and rainforests, as well as other areas, the vast majority of these extinctions are thought to be undocumented, as the species are undiscovered at the time of their extinction, which goes unrecorded. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background extinction rates, and is increasing. During the past 100–200 years, biodiversity loss and species extinction have accelerated, to the point that most conservation biologists now believe that humankind has either entered a period of mass extinction, or is on the ...

Biodiversity Of New Caledonia
The biodiversity of New Caledonia is of exceptional biological and paleoecological interest. It is frequently referred to as a biodiversity hotspot.Myers, Norman; Mittermeier, Russell A. ; Mittermeier, Cristina G.; da Fonseca, Gustavo A. B.; Kent, Jennifer. Biodiversity hotspots for conservation priorities. Nature 403, 853-858 (24 February 2000) , ; Received 22 September 1999 The country is a large South Pacific archipelago with a total land area of more than . The terrain includes a variety of reefs, atolls, small islands, and a variety of topographical and edaphic regions on the largest island, all of which promote the development of unusually concentrated biodiversity. The region's climate is oceanic and tropical. New Caledonia is separated from the nearest mainland by more than of open sea. Its isolation dates from at least the mid-Miocene, and possibly from the Oligocene, and that isolation has preserved its relict biota, fostering the evolution of wide ranges of endem ...

Oral History
Oral history is the collection and study of historical information about individuals, families, important events, or everyday life using audiotapes, videotapes, or transcriptions of planned interviews. These interviews are conducted with people who participated in or observed past events and whose memories and perceptions of these are to be preserved as an aural record for future generations. Oral history strives to obtain information from different perspectives and most of these cannot be found in written sources. ''Oral history'' also refers to information gathered in this manner and to a written work (published or unpublished) based on such data, often preserved in archives and large libraries.oral history.

Kanak People
The Kanak ( French spelling until 1984: Canaque) are the indigenous Melanesian inhabitants of New Caledonia, an overseas collectivity of France in the southwest Pacific. According to the 2019 census, the Kanak make up 41.2% of New Caledonia's total population — corresponding to around 112,000 people. The Kanak population is traditionally contrasted with two other groups of European descent: (1) the Caldoche, who were born in New Caledonia; and (2) the Zoreille, who live in the territory yet were born in metropolitan France. The earliest traces of human settlement in New Caledonia go back to Lapita culture, about 3000 BP, i.e. 1000 BCE. In addition, Polynesian seafarers have intermarried with the Kanaks over the last centuries. New Caledonia was annexed to France in 1853, and became an overseas territory of France in 1956. An independence movement, which led to a failed revolt in 1967, was restarted in 1984, pursuing total independence from French rule. When the 1988 ...

Lapita
The Lapita culture is the name given to a Neolithic Austronesian people and their material culture, who settled Island Melanesia via a seaborne migration at around 1600 to 500 BCE. They are believed to have originated from the northern Philippines, either directly, via the Mariana Islands, or both. They were notable for their distinctive geometric designs on dentate-stamped pottery, which closely resemble the pottery recovered from the Nagsabaran archaeological site in northern Luzon. The Lapita intermarried with the Papuans, Papuan populations to various degrees, and are the direct ancestors of the Austronesian peoples of Polynesia, eastern Micronesia, and Island Melanesia. Etymology The term 'Lapita' was coined by archaeologists after mishearing a word in the local Haveke language, ''xapeta'a'', which means 'to dig a hole' or 'the place where one digs', during the 1952 excavation in New Caledonia. The Lapita archaeological culture is named after the type site where it was fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pile-builder Megapode
The pile-builder megapode (''Megapodius molistructor'') is an extinct species of megapode. The subfossil remains were found by Jean-Christophe Balouet and Storrs L. Olson in the Pindai Caves of New Caledonia. Its remains have also been found on Tonga Tonga (, ; ), officially the Kingdom of Tonga ( to, Puleʻanga Fakatuʻi ʻo Tonga), is a Polynesian country and archipelago. The country has 171 islands – of which 45 are inhabited. Its total surface area is about , scattered over in .... Description With a weight of 3.5 kg, ''M. molistructor'' was heavier than all existing ''Megapodius'' species. On Tonga, it was the largest ground-dwelling bird species. The fossil material consists of a left tarsometatarsus, a complete left scapula, a half right scapula, a proximal-end left ulna, a fragment of the right femur, several ungual phalanges, an anterior-end right scapula, a proximal-end right ulna, a distal left ulna, a distal-end left ulna proximal, and a half ...

Grave Goods
Grave goods, in archaeology and anthropology, are the items buried along with the body. They are usually personal possessions, supplies to smooth the deceased's journey into the afterlife or offerings to the gods. Grave goods may be classed as a type of votive deposit. Most grave goods recovered by archaeologists consist of inorganic objects such as pottery and stone and metal tools but organic objects that have since decayed were also placed in ancient tombs. The grave goods were to be useful to the deceased in the afterlife; therefore their favorite foods or everyday objects were left with them. Often times social status played a role in what was left and how often it was left. Funerary art is a broad term but generally means artworks made specifically to decorate a burial place, such as miniature models of possessions including slaves or servants for "use" in the afterlife. Although, in ancient Egypt they would sometimes bury the real servants with the deceased. Where grave go ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clutch (animal)
__NOTOC__ A clutch of eggs is the group of eggs produced by birds, amphibians, or reptiles, often at a single time, particularly those laid in a nest. In birds, destruction of a clutch by predators (or removal by humans, for example the California condor breeding program) results in ''double-clutching''. The technique is used to double the production of a species' eggs, in the California condor case, specifically to increase population size. The act of putting one's hand in a nest to remove eggs is known as "dipping the clutch". Size Clutch size differs greatly between species, sometimes even within the same genus. It may also differ within the same species due to many factors including habitat, health, nutrition, predation pressures, and time of year. Clutch size variation can also reflect variation in optimal reproduction effort. In birds, clutch size can vary within a species due to various features (age and health of laying female, ability of male to supply food, and abun ...

Dinosaur
Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago (mya), although the exact origin and timing of the evolution of dinosaurs is the subject of active research. They became the dominant terrestrial vertebrates after the Triassic–Jurassic extinction event 201.3 mya; their dominance continued throughout the Jurassic and Cretaceous periods. The fossil record shows that birds are feathered dinosaurs, having evolved from earlier theropods during the Late Jurassic epoch, and are the only dinosaur lineage known to have survived the Cretaceous–Paleogene extinction event approximately 66 mya. Dinosaurs can therefore be divided into avian dinosaurs—birds—and the extinct non-avian dinosaurs, which are all dinosaurs other than birds. Dinosaurs are varied from taxonomic, morphological and ecological standpoints. Birds, at over 10,700 living species, are among ...
