Kimberley Rockhole Frog
The Kimberley rockhole frog (''Litoria aurifera'') is a species of small treefrog that is endemic to Western Australia. The species epithet ''aurifera'' (‘gold-bearing’) refers to the colouring of the tadpoles. History The species was described in 2010 following the discovery by botanists Matt and Russell Barrett of its distinctive tadpoles in shallow water near the Prince Regent River in the tropical Kimberley region of north-west Australia. Description The species is similar in appearance to the common rockhole frog (''Litoria meiriana''). It grows up to 22 mm long, and has small limbs with fully webbed toes. The tadpoles have black bodies with gold patches on the snout and back. The metamorphs are about 11 mm long. Distribution and habitat The frog has a restricted range in rugged sandstone country, from Walcott Inlet Walcott Inlet is an estuary located in the Kimberley region of Western Australia. It flows into Collier Bay, in the Indian Ocean, via ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sandstone
Sandstone is a Clastic rock#Sedimentary clastic rocks, clastic sedimentary rock composed mainly of grain size, sand-sized (0.0625 to 2 mm) silicate mineral, silicate grains, Cementation (geology), cemented together by another mineral. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar, because they are the most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand, sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topography, topographic features, certain colors of sandstone have become strongly identified with certain regions, such as the red rock deserts of Arches National Park and other areas of the Southwestern United States, American Southwest. Rock formations composed of sandstone usually allow the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amphibians Described In 2010
Amphibians are ectothermic, anamniote, anamniotic, tetrapod, four-limbed vertebrate animals that constitute the class (biology), class Amphibia. In its broadest sense, it is a paraphyletic group encompassing all Tetrapod, tetrapods, but excluding the amniotes (tetrapods with an amniotic membrane, such as modern reptiles, birds and mammals). All extant taxon, extant (living) amphibians belong to the monophyletic subclass (biology), subclass Lissamphibia, with three living order (biology), 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 ecosystem, freshwater, wetland or terrestrial ecosystems (such as riparian woodland, fossorial and even arboreal habitats). Their biological life cycle, life cycle typically starts out as aquatic animal, aquatic larvae with gills known as tadpoles, but some species have devel ...

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] |
Frogs Of Australia
Amphibians of Australia are limited to members of the order List of Anuran families, 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 (ecology), endemic. Compared with other continents, species diversity is low, and may be related to the climate of most of the Australia (continent), Australian continent. There are two known invasive species, 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, 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Australia
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 becomin ...

Litoria
''Litoria'' is a genus of Hylidae, hylid tree frogs, sometimes collectively referred to as Australasian treefrogs. Description The species within the genus ''Litoria'' are extremely variable in appearance, behaviour, and habitat. The smallest species is the javelin frog (''L. microbelos''), reaching a maximum snout–to–Cloaca, vent length of , while the largest, the giant tree frog (''L. infrafrenata''), reaches a size of . They are distinguishable from other tree frogs by the presence of horizontal irises, no pigmentation of the eyelids, and their distribution east and south from Wallacea. Over one hundred species are recognised and new species are still being added, such as the Pinocchio frog discovered in 2008 and described in 2019. Distribution and habitat The frogs are native to Australia, the Bismarck Archipelago, the Solomon Islands, New Guinea, the Lesser Sunda Islands, and the Moluccan Islands. The appearance, behaviour and habitat of each species are usually linked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prince Regent National Park
Prince Regent National Park, formerly the Prince Regent Nature Reserve, is a protected area in the Kimberley region of Western Australia. In 1978 the area was nominated as a UNESCO World Biosphere Reserve. Land The national park covers a total area of and was created in 1964 to protect the catchment area of the Prince Regent River. The northern boundary of the national park abuts the southern boundary of the Mitchell River National Park creating a protected area of over . The landscape of the reserve ranges from lush rainforest to sandstone plains. The area contains gorges, waterfalls, cliffs and mountain ranges. Careening Bay, on Coronation Island, site of "The Mermaid Tree" (after , Philip Parker King's ship) is within the park. The boab tree was inscribed by the ship's carpenter when the vessel was deliberately careened (beached) in order to undertake repairs.

Walcott Inlet
Walcott Inlet is an estuary located in the Kimberley region of Western Australia. It flows into Collier Bay, in the Indian Ocean, via a narrow gap known as Yule Entrance. The inlet was named on 19 June 1865 by Trevarton Charles Sholl after Stephen Walcott, Commissioner of the Government Emigration Board, while on an exploratory expedition from the short-lived Camden Harbor settlement (in Camden Sound). The inlet is in length, with a width of and covering an area of . It is tide-dominated, and in nearly pristine condition with a catchment area of . The entry to the inlet, known as Yule Entrance, On the Department of Agriculture, Water and the Environment websithere Date assumed per last date mentioned in publication (2010), and author as per website. is in length and as little as wide. The mean tidal range at the mouth is , but can reach , leading to turbulence, strong tidal flows and whirlpools. Three large rivers flow into the eastern end of the inlet: Charnley Rive ...

Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, jellyfish, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis (" hemimetaboly"), or no metamorphosis (" ametaboly"). Generally organisms with a larval stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. Etymology The word ''metamorphosis'' derives from Ancient Greek , "transformation, transforming", from ('), "after" and ('), "form". Hormonal control In insects, growth and metamorphosis are controlled by hormones synthesized by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zootaxa
''Zootaxa'' is a peer-reviewed scientific mega journal for animal taxonomists. It is published by Magnolia Press (Auckland, New Zealand). The journal was established by Zhi-Qiang Zhang in 2001 and new issues are published multiple times a week. From 2001 to 2020, more than 60,000 new species have been described in the journal accounting for around 25% of all new taxa indexed in The Zoological Record in the last few years. Print and online versions are available. Temporary suspension from JCR The journal exhibited high levels of self-citation and its journal impact factor of 2019 was suspended from ''Journal Citation Reports'' in 2020, a sanction which hit 34 journals in total. Biologist Ross Mounce noted that high levels of self-citation may be inevitable for a journal which publishes a large share of new species classification. Later that year, this decision was reversed and it was admitted that levels of self-citation are appropriate considering the large proportion of p ...
