Amytornis Dorotheae
The Carpentarian grasswren (''Amytornis dorotheae'') is a species of bird in the family Maluridae. It is endemic to Australia. Its natural habitat is subtropical or tropical dry shrubland. It is threatened by habitat loss. The habitat of this species is almost exclusively on top of sandstone escarpments in the Northern Territory. In this very difficult to access terrain it is found to be not so rare. This habitat is not endangered by human encroachment other than by fires because of the extreme inaccessibility. Taxonomy and systematics The species was formerly considered to be conspecific with the white-throated grasswren. It is monotypic. Behaviour and ecology Diet Feeds on insects and seeds. Forages by searching rock crevices and litter under shrubs on the ground.

Mount Isa
Mount Isa ( ) is a city in the Gulf Country region of Queensland, Australia. It came into existence because of the vast mineral deposits found in the area. Mount Isa Mines (MIM) is one of the most productive single mines in world history, based on combined production of lead, silver, copper and zinc. With an urban population of 18,727 in 2021 census, Mount Isa is the administrative, commercial and industrial centre for the state's vast north-western region. Although situated in an arid area, the artificial Lake Moondarra north of the city on the Leichhardt River provides both drinking water and an area for watersports, birdwatching and recreation. Locals often refer to Mount Isa as "The Isa". Due to the lead production in the city, Mount Isa has one of the most intensive air quality monitoring systems in Australia. Concerns have been raised over childhood lead contamination and air pollution within the city. The Mount Isa Mines (MIM) in particular are a source of significan ...

Gregory Mathews
Gregory Macalister Mathews Order of the British Empire, CBE FRSE FZS FLS (10 September 1876 – 27 March 1949) was an Australian-born amateur ornithologist who spent most of his later life in England. Life He was born in Biamble, New South Wales, Biamble in New South Wales the son of Robert H. Mathews. He was educated at The King's School, Parramatta. Mathews made his fortune in mining shares, and moved to England in 1902. In 1910 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were William Eagle Clarke, Ramsay Heatley Traquair, John Alexander Harvie-Brown and William Evans (naturalist), William Evans. Ornithology Mathews was a controversial figure in Australian ornithology. He was responsible for bringing trinomial nomenclature into local taxonomy, however he was regarded as an extreme splitter. He recognised large numbers of subspecies on scant evidence and few notes. The extinct Lord Howe Pigeon was described by Mathews in 1915, using a painting as ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Maluridae
The Australasian wrens are a family (biology), family, Maluridae, of small, insectivorous passerine birds endemic to Australia and New Guinea. While commonly known as wrens, they are unrelated to the wren, true wrens. The family comprises 32 species (including sixteen fairywrens, three emu-wrens, and thirteen grasswrens) in six genera. Taxonomy and systematics As with many other Australian creatures, and perhaps more than most, the species making up this family were comprehensively misunderstood by early researchers. They were variously classified as Old World flycatchers, Old World warblers, and Old World babblers. In the late 1960s morphological studies began to suggest that the Australo-Papuan fairywrens, the grasswrens, emu-wrens and two monotypic wren-like genera from New Guinea were related and, following Charles Sibley's pioneering work on egg-white proteins in the mid-1970s, Australian researchers adopted the family name Maluridae in 1975.

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical Or Tropical Dry Shrubland
Tropical and subtropical grasslands, savannas, and shrublands is a terrestrial biome defined by the World Wide Fund for Nature. The biome is dominated by grass and/or shrubs located in semi-arid to semi-humid climate regions of subtropical and tropical latitudes. Description Grassland is dominated by grass and other herbaceous plants. Savanna is grassland with scattered trees. Shrubland is dominated by woody or herbaceous shrubs. Large expanses of land in the tropics do not receive enough rainfall to support extensive tree cover. The tropical and subtropical grasslands, savannas, and shrublands are characterized by rainfall levels between per year. Rainfall can be highly seasonal, with the entire year's rainfall sometimes occurring within a couple of weeks. African savannas occur between forest or woodland regions and grassland regions. Flora includes acacia and baobab trees, grass, and low shrubs. Acacia trees lose their leaves in the dry season to conserve moisture, while t ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

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.

Amytornis
Grasswrens (''Amytornis)'' are a genus of birds in the Australasian wren family, Maluridae. Taxonomy and systematics ''Amytornis'' is the only genus classified within the subfamily Amytornithinae, and form a separate clade than the related fairy-wrens and emu-wrens within the family Maluridae. The genus contains thirteen species, many of which are poorly known due to their secretive nature and remote and inaccessible habitat. Extant species The genus contains the following species: Description Grasswrens are the largest members of the Australasian wren family, ranging from for the Eyrean grasswren to the white-throated grasswren. They generally have long tails and legs and short wings and are adapted for life foraging on the ground. The bill is typically shorter and narrower than the fairy-wrens and emu-wrens, which reflects the larger part that seeds play in their diet. The plumage of the grasswrens is cryptic, usually red, buff and brown patterned with white and black. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
