Western Pebble-mound Mouse
Western pebble-mound mouse or Ngadji, species ''Pseudomys chapmani'', is a burrowing and mound building rodent in the family Muridae. They occur in the Pilbara, a remote region in the northwest of Australia. Taxonomy The species was described by D.J. Kitchener in 1980.Pseudomys chapmani Kitchener, D.J. 1980A new species of ''Pseudomys'' (Rodentia: Muridae) from Western Australia ''Records of the Western Australian Museum'' 8:3 405-414 05 The population was formerly assumed to be species '' Pseudomys hermannsburgensis''. The description is based on a specimen that was collected at Mt Meharry (West Angelas Mine Site). The specific honours the biologist Andrew Chapman, who worked at the mammal department of the W.A. Museum. The common name according to the ''Census of Australian Vertebrates'' (ABRS 2001) is "Pebble-mound Mouse", a name given to sister taxon ''P. hermannsburgensis'' and so appended with 'Western' by the author of the species and others in later publications ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Acacia Aneura
''Acacia aneura'', commonly known as mulga or true mulga, is a shrub or small tree native to arid outback areas of Australia. It is the dominant tree in the habitat to which it gives its name ( mulga) that occurs across much of inland Australia. Specific regions have been designated the Western Australian mulga shrublands in Western Australia and Mulga Lands in Queensland. Description Mulga trees are highly variable, in form, in height, and in shape of phyllodes and seed pods. They can form dense forests up to high, or small, almost heath-like low shrubs spread well apart. Most commonly, mulgas are tall shrubs. Because the mulga is so variable, its taxonomy has been studied extensively, and although ''A. aneura'' is likely to be split into several species eventually, there is as yet no consensus on how or even if this should be done. Although generally small in size, mulgas are long-lived, a typical life span for a tree undisturbed by fire is of the order of 200 to 300 yea ...

Mammals Described In 1980
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 wit ...

Pseudomys
''Pseudomys'' is a genus of rodent that contains a wide variety of mice native to Australia and New Guinea. They are among the few terrestrial placental mammals that colonised Australia without human intervention. Natural history This genus contains a number of species with different habits making generalisation difficult. The overall body size varies widely, ranging from 60 to 160 mm. The tail is 60–180 mm and the weight is recorded from 12 to 90 g. They inhabit a wide variety of habitats from rainforests to plains and grasslands. The animals are nocturnal and spend the day in burrows. Food also varies with some species eating seeds, roots and insects while others feed primarily on grasses. The pebble-mound mice are unique in creating mounds of stones around their burrows. Several species of ''Pseudomys'' are threatened due to competition with introduced species and habitat destruction. Several others are probably extinct. Etymology The name ''Pseudomys ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Australasian Ornithologists Union
The Royal Australasian Ornithologists Union (RAOU), now part of BirdLife Australia, was Australia's largest non-government, non-profit, bird conservation organisation. It was founded in 1901 to promote the study and bird conservation, conservation of the native bird species of Australia and adjacent regions, making it Australia's oldest national birding association. In 1996, the organisation adopted the trading name of Birds Australia for most public purposes, while retaining its original name for legal purposes and as the publisher of its journal, the ''Emu (journal), Emu''. In 2012, the RAOU merged with Bird Observation & Conservation Australia to form BirdLife Australia. The RAOU was the instigator of the Atlas of Australian Birds project. It also published (in association with Oxford University Press) the encyclopaedic ''Handbook of Australian, New Zealand and Antarctic Birds''. Its quarterly colour membership magazine was ''Wingspan (magazine), Wingspan''. The RAOU is the Au ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pilbara
The Pilbara () is a large, dry, thinly populated region in the north of Western Australia. It is known for its Aboriginal peoples; its ancient landscapes; the red earth; and its vast mineral deposits, in particular iron ore. It is also a global biodiversity hotspot for subterranean fauna. Definitions of the Pilbara region At least two important but differing definitions of "the Pilbara" region exist. Administratively it is one of the nine regions of Western Australia defined by the ''Regional Development Commissions Act 1993''; the term also refers to the Pilbara shrublands bioregion (which differs in extent) under the Interim Biogeographic Regionalisation for Australia (IBRA). General The Pilbara region, as defined by the Regional Development Commissions Act 1993 and administered for economic development purposes by the Pilbara Development Commission, has an estimated population of 61,688 , and covers an area of . It contains some of Earth's oldest rock formations, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibber Plain
A desert pavement, also called reg (in the western Sahara), serir (eastern Sahara), gibber (in Australia), or saï (central Asia) is a desert surface covered with closely packed, interlocking angular or rounded rock fragments of pebble and cobble size. They typically top alluvial fans. Desert varnish collects on the exposed surface rocks over time. Geologists debate the mechanics of pavement formation and their age. Formation Several theories have been proposed for the formation of desert pavements. A common theory suggests that they form through the gradual removal of sand, dust and other fine-grained material by the wind and intermittent rain, leaving the larger fragments behind. The larger fragments are shaken into place through the forces of rain, running water, wind, gravity, creep, thermal expansion and contraction, wetting and drying, frost heaving, animal traffic, and the Earth's constant microseismic vibrations. The removal of small particles by wind does not continue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Oleosa
''Eucalyptus oleosa'', commonly known as the red mallee, glossy-leaved red mallee, acorn mallee, oil mallee or giant mallee, is a tree or mallee that is native to Australia. The leaves were once harvested for the production of cineole based eucalyptus oil. ''Eucalyptus cneorifolia'' is now the predominant strain used in production due to a higher oil content in new growth. Description ''Eucalyptus oleosa'' is a multi-stemmed tree or mallee that typically grows to a height of and has rough fibrous brown bark at the base that becomes smooth and grey above. It blooms between November and December producing yellow flowers. The adult leaves are around in length and wide. They have a narrow-lanceolate to lanceolate shape and are glossy and green in colour. The flowers are arranged in leaf axils in groups of between seven and eleven. Smooth buds form later with a length of approximately to and a width of . The bud-cap is cone-shaped to cylinder-shaped. Fruits are round-shaped wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eucalyptus Gamophylla
''Eucalyptus gamophylla'', commonly known as warilu, blue-leaved mallee, twin-leaf mallee, twin-leaved mallee or blue mallee, is a species of mallee that is native to Western Australia, South Australia and the Northern Territory. It usually has smooth bark, mostly only juvenile leaves arranged in opposite pairs, flower buds in groups of three, whitish flowers and cylindrical to barrel-shaped fruit that is four-sided in cross-section. Description ''Eucalyptus gamophylla'' is mallee that typically grows to a height of and forms a lignotuber but sometimes has an almost prostrate habit. It usually has smooth white, cream-coloured or brown bark that is shed in short ribbons but there is sometimes a stocking of rough, hard, stringy-fibrous bark at the base. Most of its leaves are juvenile, sessile, arranged in opposite pairs sometimes with their bases joined, glaucous, egg-shaped to heart-shaped, long and wide. Adult leaves, when present, are more or less in opposite pairs, the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cassia Helmsii
''Senna artemisioides'', the wormwood senna, is a species of flowering plant in the pea family Fabaceae. It is endemic to Australia, where it is found in all mainland states and territories. Other common names include silver senna, silver cassia or feathery cassia - although "cassia" generally refers to the largest-growing Cassiinae. Some of its distinct subspecies also have common names of their own. The Latin specific epithet ''artemisioides'' means “resembling ''Artemisia''”, a different group of plants often known as wormwood. Description This is an evergreen shrub that grows up to in height. It has grey-green pinnate leaves with between 1 and 8 pairs of leaflets. It produces an abundance of yellow “pea” flowers in winter and spring which are about 1.5 cm in diameter, followed by 2 to 7 cm long flat green pods which age to dark brown. The species adapts to a wide range of climatic conditions, but is susceptible to frost, especially when young. It p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
