Dasycercus
Mulgaras are the two small rat-sized species in the genus ''Dasycercus''. They are marsupial carnivores, closely related to the Tasmanian devil and the quolls, that live in deserts and spinifex grasslands of arid Australia. They are nocturnal, but occasionally "sunbathe" in the entrance of the burrow in which they dwell. Their kidneys are highly developed to excrete extremely concentrated urine to preserve water, as the animals rarely drink. They feed mostly on insects, but also eat reptiles and small mammals. They are seasonal breeders breed from June to September. The pouch comprises two lateral folds of skin. Recent research has shown two distinct species, which are very similar. The brush-tailed mulgara (''D. blythi'', previously classified as ''D.cristicauda''), has an uncrested tail, two upper premolars, and six nipples. The crest-tailed mulgara (previously ''D. hillieri'', but now reclassified as ''D. cristicauda'') has a crested tail, three upper premolars, and eight ...

Crest-tailed Mulgara
The crest-tailed mulgara (''Dasycercus cristicauda''), is a small to medium-sized Australian carnivorous marsupial and a member of the family Dasyuridae (meaning "hairy tail") which includes quolls, dunnarts, the numbat, Tasmanian devil and extinct thylacine. The crest-tailed mulgara is among a group of native predatory mammals or mesopredators endemic to arid Australia.Pavey, C. R., Nano, C. E. M., Cooper, S. J. B., Cole, J. R., & McDonald, P. J. (2012).

Angas Downs Indigenous Protected Area
Angas Downs Indigenous Protected Area (IPA) is an Aboriginal Australian-owned pastoral lease, within the MacDonnell Shire area, south-west of Alice Springs, Northern Territory, east from Uluṟu-Kata Tjuṯa National Park (Ayers Rock), south-east of Kings Canyon/Watarrka National Park and from Mount Ebenezer Roadhouse on the Lasseter Highway. The property is a pastoral lease held by the Imanpa Development Association. It was declared and formally recognised as an Indigenous Protected Area as part of the Australian Government's Caring for Country scheme on 10 June 2009. The property forms part of Australia's National Reserve System. Previous land management practices and other anthropogenic pressures had damaged Angas Downs, and many native species have disappeared. Preferred game and important animals are less common and feral animals and weeds pose a major challenge. Through the support of the Australian Government's Caring for our Country, Working on Country and Indigen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kidney
The kidneys are two reddish-brown bean-shaped organs found in vertebrates. They are located on the left and right in the retroperitoneal space, and in adult humans are about in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder. The kidney participates in the control of the volume of various body fluids, fluid osmolality, acid–base balance, various electrolyte concentrations, and removal of toxins. Filtration occurs in the glomerulus: one-fifth of the blood volume that enters the kidneys is filtered. Examples of substances reabsorbed are solute-free water, sodium, bicarbonate, glucose, and amino acids. Examples of substances secreted are hydrogen, ammonium, potassium and uric acid. The nephron is the structural and functional unit of the kidney. Each adult human kidney contains around 1 million nephrons, while a mouse kidney contains on ...

Dasyuromorphs
Dasyuromorphia (, meaning "hairy tail" in Greek) is an order comprising most of the Australian carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the thylacine. In Australia, the exceptions include the omnivorous bandicoots (order Peramelemorphia) and the marsupial moles (which eat meat but are very different and are now accorded an order of their own, Notoryctemorphia). Numerous South American species of marsupials (orders Didelphimorphia, Paucituberculata, and Microbiotheria) are also carnivorous, as were some extinct members of the order Diprotodontia, including extinct kangaroos (such as ''Ekaltadeta'' and ''Propleopus)'' and thylacoleonids, and some members of the partially extinct clade Metatheria and all members of the extinct superorder Sparassodonta. The order contains four families: one with just a single living species (the numbat), two with only extinct species (including the thylacine and ''Malleodectes''), and one, the Dasyu ...

Torpor
Torpor is a state of decreased physiological activity in an animal, usually marked by a reduced body temperature and metabolic rate. Torpor enables animals to survive periods of reduced food availability. The term "torpor" can refer to the time a hibernator spends at low body temperature, lasting days to weeks, or it can refer to a period of low body temperature and metabolism lasting less than 24 hours, as in "daily torpor". Animals that undergo daily torpor include birds (even tiny hummingbirds, notably Cypselomorphae) and some mammals, including many marsupial species, rodent species (such as mice), and bats. During the active part of their day, such animals maintain normal body temperature and activity levels, but their metabolic rate and body temperature drop during a portion of the day (usually night) to conserve energy. Some animals seasonally go into long periods of inactivity, with reduced body temperature and metabolism, made up of multiple bouts of torpor. This is kno ...

Triodia (plant Genus)
''Triodia'' is a large genus of hummock-forming bunchgrass endemic to Australia. They are known by the common name spinifex, although they are not a part of the coastal genus '' Spinifex''. Many of the soft-leaved members of this species were formerly included in the genus ''Plectrachne''. It is known as ''tjanpi'' in central Australia, and is used for basket weaving by the women of various Aboriginal Australian peoples. A multiaccess key (SpiKey) is available as a free application for identifying the ''Triodia'' of the Pilbara (28 species and one hybrid). Description ''Triodia'' is a perennial Australian tussock grass that grows in arid regions. Its leaves (30–40 centimetres long) are subulate ( awl-shaped, with a tapering point). The leaf tips, that are high in silica, can break off in the skin, leading to infections. Uses Spinifex has traditionally had many uses for Aboriginal Australians. The seeds were collected and ground to make seedcakes. Spinifex resin was a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Peters
Wilhelm Karl Hartwich (or Hartwig) Peters (22 April 1815 in Koldenbüttel – 20 April 1883) was a German natural history, naturalist and explorer. He was assistant to the anatomist Johannes Peter Müller and later became curator of the Natural History Museum, Berlin, Berlin Zoological Museum. Encouraged by Müller and the explorer Alexander von Humboldt, Peters travelled to Mozambique via Angola in September 1842, exploring the coastal region and the Zambesi River. He returned to Berlin with an enormous collection of natural history specimens, which he then described in ''Naturwissenschaftliche Reise nach Mossambique... in den Jahren 1842 bis 1848 ausgeführt'' (1852–1882). The work was comprehensive in its coverage, dealing with mammals, birds, reptiles, amphibians, river fish, insects and botany. He replaced Martin Lichtenstein as curator of the museum in 1858, and in the same year he was elected a foreign member of the Royal Swedish Academy of Sciences. In a few years, he g ...

Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
