Bettongia Anhydra
''Bettongia anhydra'', also known as desert bettong, is a recently extinct species of potoroine marsupial. Taxonomy A skull collected in the 1930s that was placed as ''Bettongia penicillata anhydra'', and later regarded as a synonym of ''Bettongia lesueur''. The first description was by Hedley Herbert Finlayson, published in 1957. An examination of morphology and molecular evidence proposed this specimen as the type of this new species. The type was collected from a fresh carcass at Lake Mackay in the western Northern Territory by Michael Terry in 1933. The phylogeny of the species separates this species and ''B. lesueur'' from lineages that emerged at a later period. Description A species of genus ''Bettongia Bettongs, species of the genus ''Bettongia'', are potoroine marsupials once common in Australia. They are important ecosystem engineers displaced during the colonisation of the continent, and are vulnerable to threatening factors such as alte ...'', small to me ...

Potoroine
Potoroidae is a family of marsupials, small Australian animals known as bettongs, potoroos, and rat-kangaroos. All are rabbit-sized, brown, jumping marsupials and resemble a large rodent or a very small wallaby. Taxonomy The potoroids are smaller relatives of the kangaroos and wallabies, and may be ancestral to that group. In particular, the teeth show a simpler pattern than in the kangaroo family, with longer upper incisors, larger canines, and four cusps on the molars. However, both groups possess a wide diastema between the incisors and the cheek teeth, and the potoroids have a similar dental formula to their larger relatives: In most respects, however, the potoroids are similar to small wallabies. Their hind feet are elongated, and they move by hopping, although the adaptations are not as extreme as they are in true wallabies, and, like rabbits, they often use their fore limbs to move about at slower speeds. The potoroids are, like nearly all diprotodonts, herbivorou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bettongia Lesueur
The boodie (''Bettongia lesueur''), also known as the burrowing bettong or Lesueur's rat-kangaroo, is a small, furry, rat-like mammal native to Australia. Once common throughout the continent, it is now restricted to a few coastal islands. A member of the rat-kangaroo family (Potoroidae), it lives in burrows and is active at night when it forages for fungi, roots, and other plant matter. It is about the size of a rabbit and, like other Marsupial, marsupials, carries its young in a pouch. Before European settlement, it was the most common Macropodiformes, macropod in Australia (a group that includes Kangaroo, kangaroos, Wallaby, wallabies, and other Australian mammals). Competition and predation by introduced rabbits, cats, and foxes, as well as habitat loss, pressured the population. It was declared a pest in the 1900s and was wiped out by the 1960s; however, the loss of the boodie and other ground-foraging animals has degraded soil quality. Populations persisted on three west coa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hedley Herbert Finlayson
Hedley Herbert Finlayson (1895–1991) was an Australian mammalogist, author and photographer. Associated with the South Australian Museum, he is recognised for his extensive surveys and research on mammals in Central Australia and systematically documenting the knowledge of the Indigenous peoples of the region. Early life Born in the Australian city of Adelaide, the fourth of the five surviving children of Finette (Nettie) Finlayson née Champion, wife of Ebenezer Finlayson, an influential financier, political activist and writer at state newspaper ''The Register''. He was schooled at Kyre College in Mitcham, South Australia (now Scotch College), and studied science at the state's university. Works Chemistry While studying at the University of South Australia, Finlayson became employed in a junior role by the chemistry department as a demonstrator, remaining in this position until 1918. Finlayson was injured in a series of laboratory accidents during his early career, inclu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Mackay
Lake Mackay, known as Wilkinkarra to the Indigenous Pintupi people, is the largest of hundreds of ephemeral salt lakes scattered throughout the Pilbara and northern parts of the Goldfields-Esperance region of Western Australia and the Northern Territory. It is located within the Great Sandy Desert. The lake is the largest in Western Australia and has a surface area of . Its elevation ranges between and above mean sea-level. Description Lake Mackay is the fourth largest lake in Australia. It measures approximately east-west and north-south. The darker areas of the lakebed are indicative of some form of desert vegetation or algae, some moisture within the soils of the dry lake, and the lowest elevations where pooling of water occurs. In this arid environment, salts and other minerals are carried to the surface through capillary action caused by evaporation, thereby producing the white reflective surface. Visible are various brown hills scattered across the eastern half of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Terry (explorer)
Michael Terry, FRGS, FRGSA (3 May 1899 – 1981) was an Australian explorer, surveyor, prospector and writer. Biography Terry was born at Gateshead, County Durham, England. During the First World War he served with No. 2 Squadron of the RNAS Armoured Cars in Russia against the Bolsheviks, by whom he was captured at Kursk though subsequently released. He moved to Australia in 1918. Between 1923 and 1935 he led fourteen, mainly gold prospecting, expeditions through inland Australia; he wrote several books and articles in ''Walkabout'', about his experiences.

Bettongia
Bettongs, species of the genus ''Bettongia'', are potoroine marsupials once common in Australia. They are important ecosystem engineers displaced during the colonisation of the continent, and are vulnerable to threatening factors such as altered fire regimes, land clearing, pastoralism and introduced predatory species such as the fox and cat. Conservation status All species of the genus have been severely affected by ecological changes since the European settlement of Australia. Those that have not become extinct became largely confined to islands and protected reserves and are dependent on re-population programs. The diversity of the genus was poorly understood before their extirpation from the mainland, and new taxa have been identified in specimens newly discovered and already held in museum collections. In 2021 August, 40 Bettongs were released in different parts of South Australia; they were raised in captivity to increase their numbers. Taxonomy Four extant species ...

Fungivorous
Fungivory or mycophagy is the process of organisms consuming fungi. Many different organisms have been recorded to gain their energy from consuming fungi, including birds, mammals, insects, plants, amoebas, gastropods, nematodes, bacteria and other fungi. Some of these, which only eat fungi, are called fungivores whereas others eat fungi as only part of their diet, being omnivores. Animals Mammals Many mammals eat fungi, but only a few feed exclusively on fungi; most are opportunistic feeders and fungi only make up part of their diet. At least 22 species of primate, including humans, bonobos, colobines, gorillas, lemurs, macaques, mangabeys, marmosets and vervet monkeys are known to feed on fungi. Most of these species spend less than 5% of the time they spend feeding eating fungi, and fungi therefore form only a small part of their diet. Some species spend longer foraging for fungi, and fungi account for a greater part of their diet; buffy-tufted marmosets spend up to 12% of their ...

Extinct Mammals Of Australia
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
