Western Swamp Turtle
The western swamp turtle or western swamp tortoise (''Pseudemydura umbrina'') is a critically endangered species of freshwater turtle endemic to a small portion of Western Australia. It is the only member of the genus ''Pseudemydura'' in the monotypic subfamily Pseudemydurinae. It is the sister taxon to the subfamily Chelodininae. As a consequence of the greatly altered habitat in the area in which it occurs near Perth, Western Australia, it exists in small fragmented populations, making the species critically endangered. Taxonomy The accepted description of the species by Friedrich Siebenrock was published in 1901. The first specimen of the western swamp tortoise was collected by Ludwig Preiss in 1839 and sent to Vienna Museum. There it was labelled "New Holland" and was named ''Pseudemydura umbrina'' 1901 by Seibenrock. No further specimens were found until 1953. In 1954, Ludwig Glauert named these specimens ''Emydura inspectata'', but in 1958, Ernest Williams of Harvard ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chelidae
Chelidae is one of three living families of the turtle suborder Pleurodira, and are commonly called Austro-South American side-neck turtles. The family is distributed in Australia, New Guinea, parts of Indonesia, and throughout most of South America. It is a large family of turtles with a significant fossil history dating back to the Cretaceous. The family is entirely Gondwanan in origin, with no members found outside Gondwana, either in the present day or as a fossil.Georges, A. & Thomson, S. (2006). "Evolution and Zoogeography of Australian freshwater turtles". In: Merrick, J. R.; Archer, M.; Hickey, G. & Lee, M. (eds.) ''Evolution and Zoogeography of Australasian Vertebrates''. Sydney: Australia. Description Like all pleurodirous turtles, the chelids withdraw their necks sideways into their shells, differing from cryptodires that fold their necks in the vertical plane. They are all highly aquatic species with webbed feet and the capacity to stay submerged for long periods of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Described In 1901
Reptiles, as commonly defined, are a group of tetrapods with an ectothermic metabolism and amniotic development. Living traditional reptiles comprise four orders: Testudines, Crocodilia, Squamata, and Rhynchocephalia. About 12,000 living species of reptiles are listed in the Reptile Database. The study of the traditional reptile orders, customarily in combination with the study of modern amphibians, is called herpetology. Reptiles have been subject to several conflicting taxonomic definitions. In Linnaean taxonomy, reptiles are gathered together under the class Reptilia ( ), which corresponds to common usage. Modern cladistic taxonomy regards that group as paraphyletic, since genetic and paleontological evidence has determined that birds (class Aves), as members of Dinosauria, are more closely related to living crocodilians than to other reptiles, and are thus nested among reptiles from an evolutionary perspective. Many cladistic systems therefore redefine Reptilia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vulpes Vulpes
The red fox (''Vulpes vulpes'') is the largest of the true foxes and one of the most widely distributed members of the order Carnivora, being present across the entire Northern Hemisphere including most of North America, Europe and Asia, plus parts of North Africa. It is listed as least concern on the IUCN Red List. Its range has increased alongside human expansion, having been Foxes in Australia, introduced to Australia, where it is considered harmful to native small and medium-sized rodents and marsupials. Due to its impact on native species, it is included on the list of the "List of the world's 100 worst invasive species, world's 100 worst invasive species". The red fox originated in Eurasia during the Middle Pleistocene at least 400,000 years ago and later colonised North America sometime prior to 130,000 years ago. Among the true foxes, the red fox represents a more progressive form in the direction of Carnivore, carnivory. Apart from its large size, the red fox is distin ...

Intensive Agriculture
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area. It is characterized by a low fallow ratio, higher use of inputs such as capital, labour, agrochemicals and water, and higher crop yields per unit land area. Most commercial agriculture is intensive in one or more ways. Forms that rely heavily on industrial methods are often called industrial agriculture, which is characterized by technologies designed to increase yield. Techniques include planting multiple crops per year, reducing the frequency of fallow years, improving cultivars, mechanised agriculture, controlled by increased and more detailed analysis of growing conditions, including weather, soil, water, weeds, and pests. Modern methods frequently involve increased use of non-biotic inputs, such as fertil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urbanisation
Urbanization (or urbanisation in British English) is the population shift from rural to urban areas, the corresponding decrease in the proportion of people living in rural areas, and the ways in which societies adapt to this change. It can also mean population growth in urban areas instead of rural ones. It is predominantly the process by which towns and cities are formed and become larger as more people begin to live and work in central areas. Although the two concepts are sometimes used interchangeably, urbanization should be distinguished from urban growth. Urbanization refers to the ''proportion'' of the total national population living in areas classified as urban, whereas urban growth strictly refers to the ''absolute'' number of people living in those areas. It is predicted that by 2050, about 64% of the developing world and 86% of the developed world will be urbanized. This is predicted to generate artificial scarcities of land, lack of drinking water, playgrounds and o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darling Scarp
The Darling Scarp (), also referred to as the Darling Range or Darling Ranges, is a low escarpment running north–south to the east of the Swan Coastal Plain and Perth, Western Australia. The escarpment extends generally north of Bindoon, to the south of Pemberton. The adjacent Darling Plateau goes easterly to include Mount Bakewell near York and Mount Saddleback near Boddington. It was named after the Governor of New South Wales, Lieutenant-General Ralph Darling. History The feature was first recorded as General Darling Range by Charles Fraser, Government Botanist with Captain James Stirling aboard in March 1827. Maps from the 1830s show the scarp labelled '' General Darlings Range''; this later became ''Darling Range'', a name by which the formation was still commonly known in the late 20th century despite common understanding of it being an escarpment. There is also a tendency to identify the locations on or to the east of the scarp as being in the '' Perth Hills' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bullsbrook, Western Australia
Bullsbrook (formerly Bullsbrook East) is a northern suburb of Perth, Western Australia in the outer metropolitan area. It is located in the City of Swan. The original Bullsbrook townsite is located slightly west of the current town, on the 17 kiometres mark of the Midland Railway. Bullsbrook is also home to the RAAF Pearce airbase, a major training facility for the Royal Australian Air Force. The suburb is situated on the Great Northern Highway, 25 kilometres north of the Midland Strategic Regional Centre. It is well serviced by several major transport networks including the Great Northern Highway, Railway Parade and the Brand Highway to the north, Chittering Road to the east and Tonkin Highway and Neaves Road to the west. Bullsbrook is also adjacent to the State rail network, providing an opportunity for the development of an intermodal freight transport hub. The site is further strengthened by linkage to the planned Perth-Darwin National Highway via Stock Road. Although ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAAF Base Pearce
RAAF Base Pearce is the main Royal Australian Air Force (RAAF) military air base in Western Australia, located in Bullsbrook, north of Perth. It is used for training by the RAAF and the Republic of Singapore Air Force. Pearce is the busiest RAAF base in Australia, with the highest air traffic including civil flights, including civil movements at the Joint User bases. Although its primary role is pilot training, it remains the only permanent RAAF base on the west coast, and thus has a significant logistics role. Pearce also has operational responsibility for RAAF Gingin, a small military airfield used for flying training, located north of Pearce. When requested by the flying units, a rotation of air traffic controllers travel from Pearce to Gingin daily to provide services. History Built between 1936 and 1939, RAAF Base Pearce was officially granted "station" status on 6 February 1939. It was named in honour of Sir George Pearce, a Senator from Western Australia.
