Central Ranges Toadlet
The Central Ranges toadlet (''Pseudophryne robinsoni''), or Everard Ranges toadlet, is a species of small frog that is endemic to Australia. History The species was first discovered by Mike Tyler in 1970, but was thought at the time to be an isolated eastern population of '' Pseudophryne occidentalis'', and was not formally described until 2012. The specific epithet honours Dr Tony Robinson, formerly of the South Australian Department for the Environment and Natural Resources. Description The species grows to 23–26 mm (males) and 27–28 (females) in length ( SVL). Colouration of the warty upper body is pale brown, khaki or grey, with dark blotches, and with pale orange-brown patches on the upper arms; the belly is smooth and black with white markings; the limbs are short, with unwebbed toes and fingers. Distribution and habitat The species occurs in the arid Everard and Musgrave Ranges of extreme north-western South Australia, in Australia's Central Ranges bioregion ...

Steve Donnellan (scientist)
Stephen Charles Donnellan (born 1954) is the Chief Research Scientist of the Evolutionary Biology Unit at the South Australian Museum. He is also an Affiliate Professor at the University of Adelaide. Donnellan moved from New South Wales to South Australia in 1985 to undertake research recovering the evolutionary history of Australia's lizards. This work led to the establishment of a comprehensive collection of reptile and frog tissues from Australia and New Guinea. In 1990 Donnellan joined the South Australian Museum's staff and established the DNA laboratory there. His research since has focused on the evolution and biogeography of Australasian fauna. Donnellan has used molecular genetic methods to examine issues in the population genetics, phylogeography and phylogenetic relationships of vertebrates and selected invertebrate groups. Many of his research projects have been supported by the Australian Research Council (ARC). His work has been published in numerous scientific journals ...

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] |

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called nomenclature ("two-name naming system") or binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen, name or a scientific name; more informally it is also historically called a Latin name. The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Homo sapiens''. ''Tyrannosaurus rex'' is likely the most widely known binomial. The ''formal'' introduction of this system of naming species is credit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Everard Ranges
The Everard Ranges, officially known as The Everard Ranges, is a range of low rounded granite hills located in the Australian state of South Australia in the Aṉangu Pitjantjatjara Yankunytjatjara lands about west of Mintabie. It is of Palaeocene origin between 20 and 60 million years ago, in Central Australia . Rising into domes above a Cenozoic peneplain, which is here about above sea level., they were named by Ernest Giles. after a cattle station called " Everard Park", and consist of monoliths or bornhardts, rich in caves and overhangs with Aboriginal rock painting galleries. The ranges are similar to Uluru and Kata Tjuta. Giles described them in his book, ''Australia Twice Traversed'' as follows: ''"Arriving at the first hills of the Everard, I found they were all very peculiar, bare, red, granite mounds, being the most extraordinary ranges one could possibly imagine, if indeed any one could imagine such a scene. They have thousands of acres of bare rock, pil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Musgrave Ranges
Musgrave Ranges is a mountain range in Central Australia, straddling the boundary of South Australia (Anangu Pitjantjatjara Yankunytjatjara) and the Northern Territory (MacDonnell Shire), extending into Western Australia. It is between the Great Victoria Desert to the south and the Gibson Desert to the north. They have a length of and many peaks that have a height of more than , the highest being Mount Woodroffe at . Inhabitants They were originally inhabited by the indigenous Yankunytjatjara people. The English explorer William Gosse and his team were the first white people to visit the region in the 1870s. Gosse named the mountains after Anthony Musgrave, then Governor of South Australia. At the start of the 20th century, Yankunytjatjara people began migrating east, and groups of Pitjantjatjara moved into the Musgrave region from the west. Today, the majority of the families in the communities of Amata and Kaltjiti identify as Pitjantjatjara. In a historic decision freehold ...

South Australia
South Australia (commonly abbreviated as SA) is a state in the southern central part of Australia. It covers some of the most arid parts of the country. With a total land area of , it is the fourth-largest of Australia's states and territories by area, and second smallest state by population. It has a total of 1.8 million people. Its population is the second most highly centralised in Australia, after Western Australia, with more than 77 percent of South Australians living in the capital Adelaide, or its environs. Other population centres in the state are relatively small; Mount Gambier, the second-largest centre, has a population of 33,233. South Australia shares borders with all of the other mainland states, as well as the Northern Territory; it is bordered to the west by Western Australia, to the north by the Northern Territory, to the north-east by Queensland, to the east by New South Wales, to the south-east by Victoria, and to the south by the Great Australian Bight.M ...
