Frill Lizard
The frilled lizard (''Chlamydosaurus kingii''), also known as the frill-necked lizard or frilled dragon, is a species of lizard in the family Agamidae. It is native to northern Australia and southern New Guinea. This species is the only member of the genus ''Chlamydosaurus''. Its common names come from the large frill around its neck, which usually stays folded against the lizard's body. It reaches from head to tail and can weigh . Males are larger and more robust than females. The frilled lizard is largely arboreal, spending most of its time in the trees. Its diet consists mainly of insects and other invertebrates. It is more active during the wet season, which is when it breeds and spends more time near or on the ground. It is less observed during the dry season, during which it seeks shade in the branches of the upper canopy. The lizard uses its frill to scare off predators and display to other individuals. The species' distinctive appearance has been used in films and TV. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Ancient Greek
Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic period (), and the Classical period (). Ancient Greek was the language of Homer and of fifth-century Athenian historians, playwrights, and philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Epic and Classical periods of the language. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regarded as a separate historical stage, although its earliest form closely resembles Attic Greek and its latest form approaches Medieval Greek. There were several regional dialects of Ancient Greek, of which Attic Greek developed into Koi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lophognathus Gilberti 1
''Lophognathus'' is a genus of large-bodied agamid lizards, consisting of two species — ''L. gilberti'' and ''L. horneri'' — both of which are endemic to northern Australia. Along with several other closely related genera (e.g., ''Amphibolurus'', ''Gowidon'', and '' Tropicagama''), these lizards are commonly referred to as "dragons". In Australia, these lizards are also colloquially known as "Ta Ta" lizards, due to their habit of "waving" after running across hot surfaces. ''Lophognathus'' are slender, slightly compressed, semi-arboreal lizards. They occur in a variety of habitats, including sand dunes and arid regions, but frequently near watercourses. The first description of a species in the genus ''Lophognathus'' was by John Edward Gray in 1842. The species he described, ''Lophognathus gilberti'', was named after English naturalist John Gilbert, the collector of the type specimen.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011).

Cladogram
A cladogram (from Greek ''clados'' "branch" and ''gramma'' "character") is a diagram used in cladistics to show relations among organisms. A cladogram is not, however, an evolutionary tree because it does not show how ancestors are related to descendants, nor does it show how much they have changed, so many differing evolutionary trees can be consistent with the same cladogram. A cladogram uses lines that branch off in different directions ending at a clade, a group of organisms with a last common ancestor. There are many shapes of cladograms but they all have lines that branch off from other lines. The lines can be traced back to where they branch off. These branching off points represent a hypothetical ancestor (not an actual entity) which can be inferred to exhibit the traits shared among the terminal taxa above it. This hypothetical ancestor might then provide clues about the order of evolution of various features, adaptation, and other evolutionary narratives about an ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...

Allopatric
Allopatric speciation () – also referred to as geographic speciation, vicariant speciation, or its earlier name the dumbbell model – is a mode of speciation that occurs when biological populations become geographically isolated from each other to an extent that prevents or interferes with gene flow. Various geographic changes can arise such as the movement of continents, and the formation of mountains, islands, bodies of water, or glaciers. Human activity such as agriculture or developments can also change the distribution of species populations. These factors can substantially alter a region's geography, resulting in the separation of a species population into isolated subpopulations. The vicariant populations then undergo genetic changes as they become subjected to different selective pressures, experience genetic drift, and accumulate different mutations in the separated populations' gene pools. The barriers prevent the exchange of genetic information between th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape York (Queensland)
Cape York is the northernmost point of the mainland of Australia. It is within the Shire of Torres in Queensland. History Cape York was named by Lieutenant James Cook on his first voyage of exploration along the eastern coast of Australia in 1770. He named it on 21 August 1770 "in honour of His Royal Highness, the Duke of York" referring to Prince Edward, Duke of York and Albany. Although its name derives from Cape York, the Cape York Peninsula was not named by Cook and refers to the much larger peninsula that lies between the Gulf of Carpentaria and the Coral Sea The Coral Sea () is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. The Coral Sea extends down the Australian northeast coast. Most of it is protected by the Fre .... Cook did not enter the Gulf of Carpentaria.

Kimberley (Western Australia)
The Kimberley is the northernmost of the nine regions of Western Australia. It is bordered on the west by the Indian Ocean, on the north by the Timor Sea, on the south by the Great Sandy and Tanami deserts in the region of the Pilbara, and on the east by the Northern Territory. The region was named in 1879 by government surveyor Alexander Forrest after Secretary of State for the Colonies John Wodehouse, 1st Earl of Kimberley. History The Kimberley was one of the earliest settled parts of Australia, with the first humans landing about 65,000 years ago. They created a complex culture that developed over thousands of years. Yam (''Dioscorea hastifolia'') agriculture was developed, and rock art suggests that this was where some of the earliest boomerangs were invented. The worship of Wandjina deities was most common in this region, and a complex theology dealing with the transmigration of souls was part of the local people's religious philosophy. In 1837, with expedition ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Carpentaria
The Gulf of Carpentaria (, ) is a large, shallow sea enclosed on three sides by northern Australia and bounded on the north by the eastern Arafura Sea (the body of water that lies between Australia and New Guinea). The northern boundary is generally defined as a line from Slade Point, Queensland (the northwestern corner of Cape York Peninsula) in the northeast, to Cape Arnhem on the Gove Peninsula, Northern Territory (the easternmost point of Arnhem Land) in the west. At its mouth, the Gulf is wide, and further south, . The north-south length exceeds . It covers a water area of about . The general depth is between and does not exceed . The tidal range in the Gulf of Carpentaria is between . The Gulf and adjacent Sahul Shelf were dry land at the peak of the last ice age 18,000 years ago when global sea level was around below its present position. At that time a large, shallow lake occupied the centre of what is now the Gulf. The Gulf hosts a submerged coral reef pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ord River
The Ord River is a river in the Kimberley region of Western Australia. The river's catchment covers . The lower Ord River and the conjunction with Cambridge Gulf create the most northern estuarine environment in Western Australia. The Ord River Irrigation Scheme was built in stages during the 20th century. Australia's largest artificial lake by volume, Lake Argyle, was completed in 1972. It has not been economically successful; $1.45 billion has been spent on the Ord Irrigation Scheme for a return of 17 cents on the dollar, and only 260 jobs created. The lower reaches of the river support an important wetland area known as the Ord River Floodplain, a protected area that contains numerous mangrove forests, lagoons, creeks, flats and extensive floodplains. The traditional owners are the Miriwoong and Gajerrong peoples who have inhabited the area for thousands of years and know the Ord River as .
