Ratcheting Toadlet
The ratcheting toadlet (''Uperoleia stridera'') is a species of small frog that is endemism, endemic to Australia. The Specific name (zoology), specific epithet ''stridera'', as well as the common name, refer to the grating nature of the call. Taxonomy The ratcheting toadlet was lumpers and splitters, split in 2014 from the blacksoil toadlet (''Uperoleia trachyderma''), with the populations in the western part of the range being assigned to the new species. Description The species grows to about 25 mm in length (snout-vent length, SVL). The upper body is basically brown, of shades varying from brownish grey to brownish orange, often with darker markings. The belly is white, speckled grey. The fingers and toes are unwebbed. The backs of the thighs and groin are bright red. Distribution and habitat The species' known range extends from Fitzroy Crossing, Western Australia, Fitzroy Crossing in the southern Kimberley (Western Australia), Kimberley region of Western Australia ...

Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Daly Waters, Northern Territory
Daly Waters is a town and locality in the Northern Territory of Australia, located about south of the territory capital of Darwin at the intersection of the Carpentaria Highway and the Stuart Highway. In the , the locality of Daly Waters had a population of 55 people. The area's traditional owners, the Jingili people, believe the Dreaming tracks of the Emu and the Sun travelled through here on their way to the southern parts of the Northern Territory. History The name Daly Waters was given to a series of natural springs by John McDouall Stuart during his third attempt to cross Australia from south to north, in 1861–62. Stuart named the springs after the new Governor of South Australia, Sir Dominick Daly. Stuart's first attempt, in 1860, had reached Tennant Creek. The second, in early 1861, pushed further north but again Stuart turned back. The third journey left Adelaide in October 1861 and reached Daly Waters on 28 May. The party had been pushing through difficult la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of Western Australia
The Amphibians of Western Australia are represented by two families of frogs. Of the 78 species found, most within the southwest, 38 are unique to the state. 15 of the 30 genera of Australian frogs occur; from arid regions and coastlines to permanent wetlands. Frog species in Western Australia have not suffered the major declines of populations and diversity of many parts of the world. No species is recorded as having become extinct, despite over 50% of recent worldwide extinctions being Australian. Three species are listed as Threatened, two as Vulnerable and '' Anstisia alba'' as Critically endangered. Threats to the species include the fungal disease Chytridiomycosis, though no infection has yet been recorded, and damage to habitat from altered land use and fire regimes. These processes have caused decline in many populations, however, some have successfully colonized newly created habitats such as dams or suburban gardens. Species such as '' Litoria moorei'' (Motorbike ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Of The Northern Territory
Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona (caecilians). Evolved to be mostly semiaquatic, amphibians have adapted to inhabit a wide variety of habitats, with most species living in freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their life cycle typically starts out as aquatic larvae with gills known as tadpoles, but some species have developed behavioural adaptations to bypass this. Young amphibians generally undergo metamorphosis from an aquatic larval form with gills to an air-breathing a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uperoleia
''Uperoleia'' is a genus of frogs in the family Myobatrachidae. They are native to northern and eastern Australia and southern lowlands of New Guinea. These are small squat frogs, more commonly known as "toadlets". They have glandular skin, often with a pair of raised glands behind each eye, or on the flanks. They have bumpy, rough skin giving them the appearance of a small toad, hence the name "toadlet", although they are often called "gungans" in Queensland. There are two distinct types of calls—''Uperoleia'' species make either a "click" or a "squelch". Generally, the "clicking" ''Uperoleia'' have long thin inguinal glands that run along the dorsal surface, while the "squelching" ''Uperoleia'' have round inguinal glands restricted to the posterior half of the dorsal surface. It is unusual to find more than one species of "clickers" or "squelchers" in the same location, although finding one of each is quite frequent in northern Australia. The species in this genus show great s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) biome and ecosystem characterised by the trees being sufficiently widely spaced so that the canopy does not close. The open canopy allows sufficient light to reach the ground to support an unbroken herbaceous layer consisting primarily of grasses. Four savanna forms exist; ''savanna woodland'' where trees and shrubs form a light canopy, ''tree savanna'' with scattered trees and shrubs, ''shrub savanna'' with distributed shrubs, and ''grass savanna'' where trees and shrubs are mostly nonexistent.Smith, Jeremy M.B.. "savanna". Encyclopedia Britannica, 5 Sep. 2016, https://www.britannica.com/science/savanna/Environment. Accessed 17 September 2022. Savannas maintain an open canopy despite a high tree density. It is often believed that savannas feature widely spaced, scattered trees. However, in many savannas, tree densities are higher and trees are more regularly spaced than in forests.Manoel Cláudio da ...

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 religi ...
