Eastern Short-eared Rock-wallaby
The eastern short-eared rock-wallaby or Wilkins' rock-wallaby (''Petrogale wilkinsi'') is a species of rock-wallaby found in the northernmost parts of the Northern Territory of Australia, and is common in the Kakadu and Litchfield National Parks. It was thought to be a subpopulation of the short-eared rock-wallaby '' Petrogale brachyotis'' found in the Kimberley (Western Australia), but recent genetic and morphological studies have shown it to be distinct. Wilkins' rock-wallaby is smaller, has more distinct grey/brown markings on its head and sides, and more colourful limbs than the western species. Taxonomy A species that emerged in results during examination of a poorly studied taxonomic complex, known as the ''brachyotis'' species group of the macropod genus ''Petrogale''. The description of the cryptic species was published in 2014 as part of a study of the phylogeny of the genus of rock-wallabies. The specific epithet commemorates the European explorer G. H. Wilkins, who ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sally Potter
Charlotte Sally Potter (born 19 September 1949) is an English film director and screenwriter. She is known for directing ''Orlando'' (1992), which won the audience prize for Best Film at the Venice Film Festival. Early life Potter was born and raised in London. Her mother was a music teacher and her father was an interior designer and a poet. Her younger brother Nic became the bassist for the rock group Van der Graaf Generator. When asked about her background, which influenced her work as a filmmaker, she responds, "I came from an atheist background and an anarchist background, which meant that I grew up in an environment that was full of questions, where nothing could be taken for granted." When asked about what she learned about filmmaking from trying to do it as a seventeen-year-old woman in the UK in the 60s, Potter laughs.You know, most kinds of securities are illusions, and we need to kind of duck and weave as filmmakers, go with the flow, go where the harvest is. ..I ...

Rock-wallaby
The rock-wallabies are the wallabies of the genus ''Petrogale''. Taxonomy The genus was established in 1837 by John Edward Gray in a revision of material at the British Museum of Natural History. Gray nominated his earlier description of ''Kangurus pencillatus'' as the type species, now recognised in the combination ''Petrogale penicillata'' (brush-tailed rock-wallaby). The author separated the species from the defunct genus ''Kangurus'', which he proposed to divide in his synopsis of the known macropod species. The following is a list of species, with common names, arranged by alliances of species groups: * Genus ''Petrogale'' ** ''P. brachyotis'' species group *** Short-eared rock-wallaby, ''Petrogale brachyotis'' *** Monjon, ''Petrogale burbidgei'' *** Nabarlek, ''Petrogale concinna'' *** Eastern short-eared rock-wallaby, ''Petrogale wilkinsi'' ** ''P. xanthopus'' species group *** Proserpine rock-wallaby, ''Petrogale persephone'' *** Rothschild's rock-wallaby, ''Petrogale r ...

Northern Territory
The Northern Territory (commonly abbreviated as NT; formally the Northern Territory of Australia) is an states and territories of Australia, Australian territory in the central and central northern regions of Australia. The Northern Territory shares its borders with Western Australia to the west (129th meridian east), South Australia to the south (26th parallel south), and Queensland to the east (138th meridian east). To the north, the territory looks out to the Timor Sea, the Arafura Sea and the Gulf of Carpentaria, including Western New Guinea and other islands of the Indonesian archipelago. The NT covers , making it the third-largest Australian federal division, and List of country subdivisions by area, the 11th-largest country subdivision in the world. It is sparsely populated, with a population of only 249,000 – fewer than half as many people as in Tasmania. The largest population center is the capital city of Darwin, Northern Territory, Darwin.

Kakadu National Park
Kakadu National Park is a protected area in the Northern Territory of Australia, southeast of Darwin. It is a World Heritage Site. Kakadu is also gazetted as a locality, covering the same area as the national park, with 313 people recorded living there in the 2016 Australian census. Water buffalo, which are now an environmental pest, were released in the area in the late 19th century, and missionaries established a mission at Oenpelli (present-day Gunbalanya) in 1925. A few pastoralists, crocodile hunters and wood cutters made a living at various times during the 20th century. The area was given protected status bit by bit from the 1970s onwards. The park is located within the Alligator Rivers Region of the Northern Territory. It covers an area of , extending nearly from north to south and over from east to west. It is roughly the size of Wales or one-third the size of Tasmania, and is the second largest national park in Australia (after the Munga-Thirri–Simpson Dese ...

Litchfield National Park
Litchfield National Park, covering approximately 1500 km2, is near the township of Batchelor, 100 km south-west of Darwin, in the Northern Territory of Australia. Each year the park attracts over 260,000 visitors. Proclaimed a national park in 1986, it is named after Frederick Henry Litchfield, a Territory pioneer, who explored areas of the Northern Territory from Escape Cliffs in Van Diemen Gulf to the Daly River in 1864. History Early history Aboriginal people have lived throughout the area for thousands of years. It is important to the Kungarakan and Marranunggu peoples for whom their ancestral spirits, still considered actively present in the landscape, played a seminal role in forming the landscape, plants and animals of this area. Recent history The park was named after Frederick Henry Litchfield, a member of the Finniss Expedition that travelled from South Australia in 1864. This was the first European expedition to visit the Top End of Australia by lan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrogale Brachyotis
The short-eared rock-wallaby (''Petrogale brachyotis'') is a species of rock-wallaby found in northern Australia, in the northernmost parts of the Northern Territory and Western Australia. It is much larger than its three closest relatives, the eastern short-eared rock-wallaby (''Petrogale wilkinsi''), the nabarlek (''Petrogale concinna'') and the monjon (''Petrogale burbidgei''). Taxonomy The species was described by John Gould in 1841. In 2014 a genetic and morphological study identified a separate species, the eastern short-eared rock-wallaby (''Petrogale wilkinsi''), previously thought to be ''P. brachyotis''. It occurs in the Kakadu and Litchfield National Parks, weighs less, and has stronger markings and colouring. Prior to a revision of the genus in 2014, a number of subspecies had been recognised. A tentative arrangement of two subspecies were proposed in that revision, identifying a taxon that may be a third species as the subspecies ''Petrogale brachyotis victo ...

Kimberley (Western Australia)
The Kimberley is the northernmost of the nine regions of Western Australia. It is bordered on the west by the Indian Ocean, on the north by the Timor Sea, on the south by the Great Sandy Desert, Great Sandy and Tanami Desert, Tanami deserts in the region of the Pilbara, and on the east by the Northern Territory. The region was named in 1879 by government surveyor Alexander Forrest after Secretary of State for the Colonies John Wodehouse, 1st Earl of Kimberley. History The Kimberley was one of the earliest settled parts of Australia, with the first humans landing about 65,000 years ago. They created a complex culture that developed over thousands of years. Yam (vegetable), Yam (''Dioscorea hastifolia'') agriculture was developed, and rock art suggests that this was where some of the earliest boomerangs were invented. The worship of Wandjina deities was most common in this region, and a complex theology dealing with the transmigration of souls was part of the local people's r ...

Macropodidae
Macropodidae is a family of marsupials that includes kangaroos, wallabies, tree-kangaroos, wallaroos, pademelons, quokkas, and several other groups. These genera are allied to the suborder Macropodiformes, containing other macropods, and are native to the Australian continent (the mainland and Tasmania), New Guinea and nearby islands. Description Although omnivorous kangaroos lived in the past, modern macropods are herbivorous. Some are browsers, but most are grazers and are equipped with appropriately specialised teeth for cropping and grinding up fibrous plants, in particular grasses and sedges. In general, macropods have a broad, straight row of cutting teeth at the front of the mouth, no canine teeth, and a gap before the molars. The molars are large and, unusually, do not appear all at once but a pair at a time at the back of the mouth as the animal ages, eventually becoming worn down by the tough, abrasive grasses and falling out. Like many Macropodiformes, early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cryptic Species
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Top End
The Top End of Australia's Northern Territory is a geographical region encompassing the northernmost section of the Northern Territory, which aside from the Cape York Peninsula is the northernmost part of the Australian continent. It covers a rather vaguely defined area of about 245,000 km² (95,000 sq mi) behind the northern coast from the Northern Territory capital of Darwin across to Arnhem Land with the Indian Ocean on the west, the Arafura Sea to the north, and the Gulf of Carpentaria to the east, and with the almost waterless semi-arid interior of Australia to the south, beyond the huge Kakadu National Park. The Top End contains both of the Territory's cities and one of its major towns, Darwin, Palmerston and Katherine. The well-known town of Alice Springs is located further south, in the arid southern part of the Northern Territory, sometimes referred to by Australians as the Red Centre. The landscape is relatively flat with river floodplains and grasslands with eucaly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
