Saccolaimus Mixtus
The Papuan sheath-tailed bat (''Saccolaimus mixtus'') is a species of bat in the family Emballonuridae which occurs at the Cape York Peninsula and New Guinea. The poorly known species hunts in open forests for night flying insects. Taxonomy The first description was published by Ellis Le Geyt Troughton in 1925. Troughton found features typical of the genus, but notes the clearly defined wing pouches that characteristic of the genus ''Taphozous''; the author makes reference to a note by Edward Ramsay in 1878 on an undiagnosed species of that genus which resembled specimens found at Cape York. Troughton describes the holotype, a male, and two other specimens, a series purchased from Kendal Broadbent who had obtained them at Port Moresby in 1878. The name was assessed in a revision of the genus in 1991, replacing the previously recognised combination ''Taphozous mixtus'' (Troughton) 1925. The number of specimens available has been limited to another two collected before 1973 in New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellis Le Geyt Troughton
Ellis Le Geyt Troughton (born in Sydney on 29 April 1893; died 30 November 1974) was an Australian zoologist and mammalogist. Biography Ellis Troughton began to exercise his interest in mammals at fourteen years of age, taking a role at the Australian Museum in 1908. He continued to be employed there as curator after returning from military service as a stretcher bearer in the European war during the years 1917 and 1918. He retired from the museum in 1958. Works Troughton wrote '' Furred Animals of Australia'' in 1941, with illustrations provided by Neville W. Cayley; the publication date of the work was determined to be 1944. He was the first Honorary Life Member of The " Australian Mammal Society" and ''The Ellis Troughton Memorial Award'' is named for him. Amongst Troughton early works is a significant contribution to the study of bats, and at 33 years of age he composed the text for the section regarding the poorly known Australian Chiroptera in the volume titled ''The ...

Tree Hollows
A tree hollow or tree hole is a semi-enclosed cavity which has naturally formed in the trunk or branch of a tree. They are found mainly in old trees, whether living or not. Hollows form in many species of trees, and are a prominent feature of natural forests and woodlands, and act as a resource or habitat for a number of vertebrate and invertebrate animals. Hollows may form as the result of physiological stress from natural forces causing the excavating and exposure of the heartwood. Forces may include wind, fire, heat, lightning, rain, attack from insects (such as ants or beetles), bacteria, or fungi. Also, trees may self-prune, dropping lower branches as they reach maturity, exposing the area where the branch was attached. Many animals further develop the hollows using instruments such as their beak, teeth or claws. The size of hollows may depend on the age of the tree. For example, eucalypts develop hollows at all ages, but only from when the trees are 120 years old do they f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Mammals Described In 1925
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Sauropsida ...

Bats Of Australia
Bats are mammals of the order Chiroptera.''cheir'', "hand" and πτερόν''pteron'', "wing". With their forelimbs adapted as wings, they are the only mammals capable of true and sustained flight. Bats are more agile in flight than most birds, flying with their very long spread-out digits covered with a thin membrane or patagium. The smallest bat, and arguably the smallest extant mammal, is Kitti's hog-nosed bat, which is in length, across the wings and in mass. The largest bats are the flying foxes, with the giant golden-crowned flying fox, ''Acerodon jubatus'', reaching a weight of and having a wingspan of . The second largest order of mammals after rodents, bats comprise about 20% of all classified mammal species worldwide, with over 1,400 species. These were traditionally divided into two suborders: the largely fruit-eating megabats, and the echolocating microbats. But more recent evidence has supported dividing the order into Yinpterochiroptera and Yangochiro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

South Australian Museum
The South Australian Museum is a natural history museum and research institution in Adelaide, South Australia, founded in 1856 and owned by the Government of South Australia. It occupies a complex of buildings on North Terrace in the cultural precinct of the Adelaide Parklands. Plans are under way to move much of its Australian Aboriginal cultural collection (the largest in the world), into a new National Gallery for Aboriginal Art and Cultures. History 19th century There had been earlier attempts at setting up mechanics' institutes in the colony, but they struggled to find buildings which could hold their library collections and provide spaces for lectures and entertainments. In 1856, the colonial government promised support for all institutes, in the form of provision the first government-funded purpose-built cultural institution building. The South Australian Institute, incorporating a public library and a museum, was established in 1861 in the rented premises of the ...

Western Australian Museum
The Western Australian Museum is a statutory authority within the Culture and the Arts Portfolio, established under the ''Museum Act 1969''. The museum has six main sites. The state museum, now known as WA Museum Boola Bardip, officially re-opened on 21 November 2020 in the Perth Cultural Centre. The other sites are: the WA Maritime Museum and WA Shipwrecks Museum in Fremantle, the Museum of the Great Southern in Albany, the Museum of Geraldton in Geraldton, and the Museum of the Goldfields in Kalgoorlie-Boulder. History Established in 1891 in the Old Perth Gaol, it was known as the Geological Museum and consisted of geological collections. In 1892, ethnological and biological exhibits were added, and in 1897, the museum officially became the Western Australian Museum and Art Gallery. The museum employed collectors to obtain series of specimens; Tunney ventured across the state from 1895 to 1909 obtaining animals and, later, the tools and artefacts of the indigenous inhabi ...

Bauxite Mining
Bauxite is a sedimentary rock with a relatively high aluminium content. It is the world's main source of aluminium and gallium. Bauxite consists mostly of the aluminium minerals gibbsite (Al(OH)3), boehmite (γ-AlO(OH)) and diaspore (α-AlO(OH)), mixed with the two iron oxides goethite (FeO(OH)) and haematite (Fe2O3), the aluminium clay mineral kaolinite (Al2Si2O5(OH)4) and small amounts of anatase (TiO2) and ilmenite (FeTiO3 or FeO.TiO2). Bauxite appears dull in luster and is reddish-brown, white, or tan. In 1821, the French geologist Pierre Berthier discovered bauxite near the village of Les Baux in Provence, southern France. Formation Numerous classification schemes have been proposed for bauxite but, , there was no consensus. Vadász (1951) distinguished lateritic bauxites (silicate bauxites) from karst bauxite ores (carbonate bauxites): * The carbonate bauxites occur predominantly in Europe, Guyana, Suriname, and Jamaica above carbonate rocks (limestone and dolom ...
