Krefft's Glider
Krefft's glider (''Petaurus notatus'') is a species of arboreal nocturnal gliding possum, a type of small marsupial. It is native to most of eastern mainland Australia and has been introduced to Tasmania. Populations of ''Petaurus'' from New Guinea and Indonesia previously classified under ''P. breviceps'' are also tentatively classified under ''P. notatus'' by the American Society of Mammalogists, but likely represent a complex of distinct species. As most captive gliders referred to as " sugar gliders" in at least the United States are thought to originate from West Papua, this likely makes them Krefft's gliders, at least tentatively. Taxonomy It is closely allied with the sugar glider (''P. breviceps''), with which it was long taxonomically confused. A 2020 study partially clarified the taxonomy of the sugar glider and split it into three species: the savanna glider (''P. ariel''), the sugar glider (''P. breviceps sensu stricto'') and Krefft's glider (''P. notatus'').

Crater Lakes National Park
Crater Lakes is a national park in Far North Queensland, Queensland, Australia, 1367 km northwest of Brisbane. The park contains two volcanically-formed lakes, Lake Barrine and Lake Eacham (Yidyam). Both lakes have walking trails around the lake; boat tours are also given at Lake Barrine. One of the recognizable features of the park are giant bull kauri pine trees (''Agathis australis''). The average elevation of the terrain is 729 meters. History In 1934, the Queensland Government created Lake Barrine National Park and Lake Eacham National Park. In 1988, UNESCO declared the Wet Tropics of Queensland a World Heritage Site with 14 areas protected, one of which was at Lake Barrine and at Lake Eacham. In 1994, the Queensland Government merged Lake Barrine National Park and Lake Eacham National Park to form Crater Lakes National Park.

Kalam Language
Kalam is a Kalam language of Papua New Guinea. It is closely related to Kobon, and shares many of the features of that language. Kalam is spoken in Middle Ramu District of Madang Province and in Mount Hagen District of Western Highlands Province. Thanks to decades of studies by anthropologists such as Ralph Bulmer and others, Kalam is one of the best-studied Trans-New Guinea languages to date. Dialects There are two distinct dialects of Kalam that are highly distinguishable from each other. *Etp, with 20,000 speakers, is centered in the Upper Kaironk and Upper Simbai Valleys. *Ti, with 5,000 speakers is centered in the Asai Valley. It includes the Tai variety. Kobon is closely related. Kalam has an elaborate pandanus avoidance register used during karuka harvest that has been extensively documented. The Kalam pandanus language, called () or (), is also used when eating or cooking cassowary. Phonology Consonants Vowels Evolution Below are some Kalam reflexes of ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), 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 Great American Interchang ...

Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Yellow-bellied Glider
The yellow-bellied glider (''Petaurus australis''), also known as the fluffy glider, is an arboreal and nocturnal gliding possum that lives in native eucalypt forests in eastern Australia, from northern Queensland south to Victoria. Habitat The yellow-bellied glider inhabits forests and woodlands in eastern Australia and is found at a range of altitudes from sea level to 1400 metres. In North Queensland, the sub-species occurs at altitudes over 700 m above sea level. With natural discontinuities and habitat clearings, there are 13 different populations in three distinct places to find this glider in North Queensland. One population resides on Mount Windsor Tableland, another on Mount Carbine Tableland, and the third lives in a linear habitat going from Atherton to Kirrama on the Atherton Tableland. These three populations together are estimated to contain around 6000 individual gliders. With their habitat in danger, the yellow-bellied glider is classified as uncommon to ...

Great Dividing Range
The Great Dividing Range, also known as the East Australian Cordillera or the Eastern Highlands, is a cordillera system in eastern Australia consisting of an expansive collection of mountain ranges, plateaus and rolling hills, that runs roughly parallel to the east coast of Australia and forms the fifth-longest land-based mountain chain in the world, and the longest entirely within a single country. It is mainland Australia's most substantial topographic feature and serves as the definitive watershed for the river systems in eastern Australia, hence the name. The Great Dividing Range stretches more than from Dauan Island in the Torres Strait off the northern tip of Cape York Peninsula, running the entire length of the eastern coastline through Queensland and New South Wales, then turning west across Victoria before finally fading into the Wimmera plains as rolling hills west of the Grampians region. The width of the Range varies from about to over .Shaw, John H., ''Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...

Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...

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 ().
