Gehyra Pulingka
''Gehyra pulingka'' (occasionally referred to as the rock-dwelling dtella, and more rarely the Umuwa spotted dtella) is a species of gecko endemic to Australia. It occurs in north-west South Australia, the mid Northern Territory, and Western Australia to the eastern Rawlinson Ranges. It is described as being generally dark-skinned with a pattern of light and dark markings over its body; however, light-skinned variants with similar patterns have been found. Etymology The species name comes from the Pitjantjatjara language Pitjantjatjara (; or ) is a dialect of the Western Desert language traditionally spoken by the Pitjantjatjara people of Central Australia. It is mutually intelligible with other varieties of the Western Desert language, and is particularly c ..., from the words ''puli'', meaning 'rock' or 'hill', and the suffix of ''ngka'', meaning 'of', or 'pertaining to'.

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 ...

Gecko
Geckos are small, mostly carnivorous lizards that have a wide distribution, found on every continent except Antarctica. Belonging to the infraorder Gekkota, geckos are found in warm climates throughout the world. They range from . Geckos are unique among lizards for their vocalisations, which differ from species to species. Most geckos in the family Gekkonidae use chirping or clicking sounds in their social interactions. Tokay geckos (''Gekko gecko'') are known for their loud mating calls, and some other species are capable of making hissing noises when alarmed or threatened. They are the most species-rich group of lizards, with about 1,500 different species worldwide. All geckos, except species in the family Eublepharidae lack eyelids; instead, the outer surface of the eyeball has a transparent membrane, the cornea. They have a fixed lens within each iris that enlarges in darkness to let in more light. Since they cannot blink, species without eyelids generally lick t ...

Endemic
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] |
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.

Rawlinson Ranges
Purli Yurliya or Rawlinson Ranges is a mountain range in the far east of central Western Australia, to the west of the Petermann Ranges, with which it is commonly associated. Both features were given their European names by Ernest Giles, the first European explorer to visit the area. The range runs roughly east from Lake Christopher for approximately . The Giles Weather Station is located a few kilometres further east. The area has been considered a possible site of the fabled Lasseter's Reef Lasseter's Reef refers to the purported discovery, announced by Harold Bell Lasseter in 1929 and 1930, of a fabulously rich gold deposit in a remote and desolate corner of central Australia.

Pitjantjatjara Dialect
Pitjantjatjara (; or ) is a dialect of the Western Desert language traditionally spoken by the Pitjantjatjara people of Central Australia. It is mutually intelligible with other varieties of the Western Desert language, and is particularly closely related to the Yankunytjatjara dialect. The names for the two groups are based on their respective words for 'come/go.' Pitjantjatjara is a relatively healthy Aboriginal language, with children learning it. It is taught in some Aboriginal schools. The literacy rate for first language speakers is 50–70%; and is 10–15% for second-language learners. There is a Pitjantjatjara dictionary, and the New Testament of the Bible has been translated into the language, a project started at the Ernabella Mission in the early 1940s and completed in 2002. Work continues on the Old Testament. Phonology and orthography There are slightly different standardised spellings used in the Northern Territory and Western Australia compared to South ...

Gehyra
''Gehyra'' is a genus of geckos in the family ''Gekkonidae''. They are known as web-toed geckos or dtellas, and most species within the genus bear close resemblance to geckos from the genus ''Hemidactylus''. Geographic range ''Gehyra'' species have a wide geographic range, covering most of the Oceania and Melanesian Islands as far north as the Ryukyu Islands and Thailand. Description Dtellas are moderately sized geckos that resemble house geckos. ''Gehyra'' species have toepads and powerful claws. Like some other geckos they also have a tendency to drop strips of skin if handled carelessly. Similar to house geckos, dtellas are able to communicate with clicks or chirps, although their chirp is often quieter than that of house geckos.

Reptiles Described In 2014
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates (lizards and snakes) and rhynchocephalians (tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated around 3 ...
