Emerald Tree Monitor
The emerald tree monitor (''Varanus prasinus'') or green tree monitor, is a small to medium-sized arboreal monitor lizard. It is known for its unusual coloration, which consists of shades from green to turquoise, topped with dark, transverse dorsal banding. This coloration helps camouflage it in its arboreal habitat. Its color also makes the emerald tree monitor highly prized in both the pet trade and zoos alike. Names It is known as wbl km in the Kalam language of Papua New Guinea. Taxonomy ''Varanus prasinus'' was first described as ''Monitor viridis'' by John Edward Gray in 1831; however, Gray's original holotype (RMNH 4812 in the National Natural History Museum in Leiden) was lost and the species was redescribed by Schlegel eight years later as ''V. prasinus'' using the found specimen. The generic name ''Varanus'' is derived from the Arabic word ''waral'' (ورل), which translates to English as "monitor". Its specific name, ''prasinus'', is Latin for the color green. ' ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjug ...

Varanus Kordensis
''Varanus kordensis'', the Biak tree monitor, is a member of the Varanidae family found on Biak Island in Indonesia. It is also known as the Kordo tree monitor. Long considered a subspecies of the emerald tree monitor (''V. prasinus''), most authorities now treat it as a separate species. Description The Biak tree monitor is mainly yellow-green, although in captivity specimens frequently lose their yellow pigment and become turquoise in color. It has a black netted pattern which is visible on its back. It reaches a total length of up to 90 cm. Captivity Kordo tree monitors are kept and occasionally bred in captivity by reptile hobbyists. Care is similar to that for other members of the ''Euprepiosaurus'' subgenus which includes the emerald tree monitor, '' Varanus prasinus''. Large, spacious, vertically oriented enclosures with many hiding spots, thick branches and cork bark tubes allow these shy, arboreal monitors to climb, hide and forage for food. Wild-caught animals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape York Peninsula
Cape York Peninsula is a large peninsula located in Far North Queensland, Australia. It is the largest unspoiled wilderness in northern Australia.Mittermeier, R.E. et al. (2002). Wilderness: Earth’s last wild places. Mexico City: Agrupación Sierra Madre, S.C. The land is mostly flat and about half of the area is used for grazing cattle. The relatively undisturbed eucalyptus-wooded savannahs, tropical rainforests and other types of habitat are now recognised and preserved for their global environmental significance. Although much of the peninsula remains pristine, with a diverse repertoire of endemic flora and fauna, some of its wildlife may be threatened by industry and overgrazing as well as introduced species and weeds.Mackey, B. G., Nix, H., & Hitchcock, P. (2001). The natural heritage significance of Cape York Peninsula. Retrieved 15 January 2008, froepa.qld.gov.au. The northernmost point of the peninsula is Cape York ().

D'Entrecasteaux Archipelago
D'Entrecasteaux Islands () are situated near the eastern tip of New Guinea in the Solomon Sea in Milne Bay Province of Papua New Guinea. The group spans a distance of , has a total land area of approximately and is separated from the Papua New Guinea mainland by the wide Ward Hunt Strait in the north and the wide Goschen Strait in the south. D'Entrecasteaux Islands show signs of volcanism. People The inhabitants of D'Entrecasteaux Islands are indigenous subsistence horticulturalists living in small, traditional settlements. People of this area produced and traded clay pots as well as participated in the Kula exchange of shell valuables, travelling widely to other islands on sea-going sailing canoes. During the more recent past, people harvested copra, trochus and pearl-shells and some timber for cash. Alluvial gold mining was once important and in recent years the area has been subject to mineral exploration. Description The three principal islands, from northwest to sou ...

Waigeo Island
Waigeo is an island in Southwest Papua province of eastern Indonesia. The island is also known as Amberi, or Waigiu. It is the largest of the four main islands in the Raja Ampat Islands archipelago, between Halmahera and about to the north-west coast of New Guinea. The Dampier Strait (a.k.a. Augusta's Strait) separates it from Batanta, and the Bougainville Strait from the Kawe Islands to its north-west.

Varanus Beccarii
The black tree monitor or Beccari's monitor (''Varanus beccarii)'' is a species of lizard in the family Varanidae. The species is a relatively small member of the family, growing to about in total length (including tail). ''V. beccarii'' is endemic to the Aru Islands off New Guinea, living in an arboreal habitat. The skin color of adults is completely black, to which one common name refers. Taxonomy ''Varanus beccarii'' was first described as ''Monitor beccarii'' by Doria, in 1874. Years later, it was classified as a subspecies of the closely related emerald tree monitor (''V. prasinus''), but a 1991 review of the complex returned ''V. beccarii'' to species status, based on its black colouration and keeled scales on the neck. Arguably, it should be maintained as a subspecies of the emerald tree monitor based on similarities in their hemipeneal structures, but genetic evidence supports their treatment as two different species. Nevertheless, it is part of the ''V. prasinus'' s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
