Rheobatrachinae
The gastric-brooding frogs or platypus frogs (''Rheobatrachus'') is a genus of extinct ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, both of which became extinct in the mid-1980s. The genus is unique because it contains the only two known frog species that incubated the prejuvenile stages of their offspring in the stomach of the mother. The combined ranges of the gastric-brooding frogs comprised less than . Both species were associated with creek systems in rainforests at elevations of between . The causes of the gastric-brooding frogs' extinction are not clearly understood, but habitat loss and degradation, pollution, and some diseases may have contributed. The assignment of the genus to a taxonomic family is hotly debated. Some biologists class them within Myobatrachidae under the subfamily Rheobatrachinae, but others place them in their own family, Rheobatrachidae.

Myobatrachidae
Myobatrachidae, commonly known as Australian ground frogs or Australian water frogs, is a family of frogs found in Australia and New Guinea. Members of this family vary greatly in size, from species less than long, to the second-largest frog in Australia, the giant barred frog (''Mixophyes iteratus''), at in length. The entire family is either terrestrial or aquatic frogs, with no arboreal species. Characteristics The family Myobatrachidae contains forms of parental care unique in the animal kingdom. The two species of gastric-brooding frog (genus: ''Rheobatrachus''), are found in this family. The females of these species swallow their young, where they develop until metamorphosis. The pouched frog (''Assa darlingtoni'') has pouches on the sides of its body. The male will guard the eggs until hatching, and assist the tadpoles into its side, where they stay until metamorphosis. Another form of parental care, although not unique, is found in many species of the genus '' Limnody ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conondale Range
The Conondale Range is a mountain range in Queensland, located between Maleny, Kenilworth, Kilcoy and Jimna. The range is the most westerly part of the Sunshine Coast hinterland and part of the Great Dividing Range. The highest point on the range is Mount Langley reaching 868 m above sea level. This is also the highest point in the Brisbane River catchment. Lower foothills of the range around Kilcoy are used for grazing. Most of the steep forested slopes of the range are state forests and Conondale National Park. In the south, parts of Stony Creek are preserved in Bellthorpe National Park. The mountains are the source of the Brisbane River. Creeks on the south of the range drain into the Stanley River and directly into Lake Somerset. To the north creeks flow into the Mary River. History Dalla (also known as Dalambara and Dallambara) is a language of the Upper Brisbane River catchment, notably the Conondale Range. Dalla is part of the Duungidjawu language region inclu ...

Amphibians Of Australia
Amphibians of Australia are limited to members of the order Anura, commonly known as frogs. All Australian frogs are in the suborder Neobatrachia, also known as the modern frogs, which make up the largest proportion of extant frog species. About 230 of the 5,280 species of frog are native to Australia with 93% of them endemic. Compared with other continents, species diversity is low, and may be related to the climate of most of the Australian continent. There are two known invasive amphibians, the cane toad and the smooth newt. Origins The Australian continent once formed part of the supercontinent Pangaea, which split into Gondwana and Laurasia approximately 180 million years ago. The earliest true frog fossil, ''Vieraella herbsti'', is dated between 188 and 213 million years old. This predates the splitting of Gondwana, and has resulted in frogs present on all continents. The first two continents to split from Australia were South America and Africa. The amphibian fauna of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dahl's Aquatic Frog
Dahl's aquatic frog (''Ranoidea dahlii'') is a species of frog in the subfamily Pelodryadinae, endemic to Australia. Its natural habitats are dry savanna, subtropical or tropical dry lowland grassland, freshwater lakes, intermittent freshwater lakes, freshwater marshes, and intermittent freshwater marshes. Dahl's aquatic frog was once thought to be able to consume the eggs, tadpoles, and young of the invasive and venomous cane toad with no apparent ill effect, but this observation was based on a handful of captive survivals. Adults regurgitate the young toads, and avoid eating them in the future, or rarely swallow them; in this case, about half the adults die. These frogs do not appear to have an elevated resistance to bufotoxins compared to other Australian hylid frogs, and avoid these toads if they survive their first toad meal.

Platypus
The platypus (''Ornithorhynchus anatinus''), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal Endemic (ecology), endemic to Eastern states of Australia, eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its Family (biology), family (Ornithorhynchidae) and genus (''Ornithorhynchus''), though a number of Fossil Monotremes, related species appear in the fossil record. Together with the four species of echidna, it is one of the five wikt:extant, extant species of monotremes, mammals that lay Egg (biology), eggs instead of giving birth to live young. Like other monotremes, it senses prey through electroreception, electrolocation. It is one of the few species of venomous mammals, as the male platypus has a spur (zoology), spur on the hind foot that delivers a Platypus venom, venom, capable of causing severe pain to humans. The unusual appearance of this egg-laying, duck-billed, beaver-t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackall Range
The Blackall Range is a mountain range in South East Queensland, Australia. The first European explorer in the area was Ludwig Leichhardt. It was named after Samuel Blackall, the second Governor of Queensland. The Blackall Range dominates the hinterland area of the Sunshine Coast, west of Nambour. Maleny, Mapleton, Montville and Flaxton are the main settlements located on the range. The Stanley River rises from the southern slopes. Baroon Pocket Dam is a reservoir on Obi Obi Creek which drains the north west slopes of the range. Mary Cairncross Reserve marks the site of the first settler's house on the Blackall Range. Curramore Sanctuary, Mapleton Falls National Park and Kondalilla National Park are also located on the range. A number of lookouts on the range provide views towards the coast. One of these is located at Howells Knob, a mountain which rises 561 m above sea level. Timber resources in the area attracted timber-cutters in 1860s. The last logging on the ran ...

Sclerophyll
Sclerophyll is a type of vegetation that is adapted to long periods of dryness and heat. The plants feature hard leaf, leaves, short Internode (botany), internodes (the distance between leaves along the stem) and leaf orientation which is parallel or oblique to direct sunlight. The word comes from the Greek ''sklēros'' (hard) and ''phyllon'' (leaf). The term was coined by Andreas Franz Wilhelm Schimper, A.F.W. Schimper in 1898 (translated in 1903), originally as a synonym of xeromorph, but the two words were later differentiated. Sclerophyllous plants occur in many parts of the world, but are most typical of areas with low rainfall or seasonal droughts, such as Australia, Africa, and western North and South America. They are prominent throughout Flora of Australia, Australia, parts of Flora of Argentina, Argentina, the Cerrado biogeographic region of Geography of Bolivia, Bolivia, Geography of Paraguay, Paraguay and Flora of Brazil, Brazil, and in the Mediterranean forests, woo ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...
