Ratcheting Toadlet
The ratcheting toadlet (''Uperoleia stridera'') is a species of small frog that is endemic to Australia. The specific epithet ''stridera'', as well as the common name, refer to the grating nature of the call. Taxonomy The ratcheting toadlet was 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 ( 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 in the southern Kimberley region of Western Australia, extending eastwards to just west of Daly Waters in the Northern Territory, in the western part of the Northern Deserts region of the conti ...

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] |

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...

Lumpers And Splitters
Lumpers and splitters are opposing factions in any discipline that has to place individual examples into rigorously defined categories. The lumper–splitter problem occurs when there is the desire to create classifications and assign examples to them, for example schools of literature, biological taxa and so on. A "lumper" is a person who assigns examples broadly, assuming that differences are not as important as signature similarities. A "splitter" is one who makes precise definitions, and creates new categories to classify samples that differ in key ways. Origin of the terms The earliest known use of these terms was by Charles Darwin, in a letter to Joseph Dalton Hooker in 1857: ''It is good to have hair-splitters & lumpers''. They were introduced more widely by George G. Simpson in his 1945 work ''The Principles of Classification and a Classification of Mammals''. As he put it: A later use can be found in the title of a 1969 paper "On lumpers and splitters ..." by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blacksoil Toadlet
The blacksoil toadlet (''Uperoleia trachyderma'') is a species of frog in the family Myobatrachidae. It is endemic to Australia. Its natural habitats are subtropical or tropical dry lowland grassland, subtropical or tropical seasonally wet or flooded lowland grassland, and intermittent freshwater marshes.

Fitzroy Crossing, Western Australia
Fitzroy Crossing is a small town in the Kimberley region of Western Australia, east of Broome and west of Halls Creek. It is approximately from the state capital of Perth. It is above sea level and is situated on a low rise surrounded by the vast floodplains of the Fitzroy River and its tributary Margaret River. At the 2016 census, the population of the Fitzroy Crossing town-site was 1,297; with a further 2,000 or so people living in up to 50 Aboriginal communities scattered throughout the Fitzroy Valley. About 80% of the Fitzroy Valley population were Indigenous Australians with a split of closer to 60/40 (indigenous/non-indigenous) in the townsite. Tourism, cattle stations and mining are the main industries in the area. History Fitzroy Crossing and the lands and valleys around it were the home for a number of Aboriginal language groups. When Fitzroy Crossing was established the main group was the Bunuba people, their land stretching from the present day Brooking Spring ...

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 ...

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. 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 lancewood scrub and harsh terrain at a little over a kilometre a day. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Savanna
A savanna or savannah is a mixed woodland-grassland (i.e. grassy woodland) 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. According to '' Britannica'', there exists four savanna forms; ''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 for ...
