Forest Toadlet
''Metacrinia'' is a genus of frog in the family Myobatrachidae. It is monotypic, being represented by the single species, ''Metacrinia nichollsi'', commonly known as the Forest toadlet or Nicholls toadlet. It is endemic to Southwest Australia, occurring between Dunsborough and Albany. Description ''Metacrinia nichollsi'' is a squat frog with short limbs and reaches in length. The dorsal colouration is very dark brown or black occasionally with pink flecks. The ventral surface is grey, dark blue or black with white marbling. There are yellow or orange markings at the base of each arm and on the underside of the thighs and lower belly. The skin on the dorsum is warty and the belly is granular. The tympanum is visible and the fingers and toes are free of webbing. It is the only described species in the genus ''Metacrinia''. The toadlet is poorly studied, but the diverse appearance of the toadlet suggests there may be more than one species. Ecology and behaviour This species is ...

Karri
''Eucalyptus diversicolor'', commonly known as karri, is a species of flowering plant in the family Myrtaceae and is Endemism, endemic to the Southwest Australia, south-west of Western Australia. It is a tall tree with smooth light grey to cream-coloured, often mottled bark, lance-shaped adult leaves and barrel-shaped fruit. Found in higher rainfall areas, karri is commercially important for its timber. Description ''Eucalyptus diversicolor'' is a tall forest tree that typically grows to a height of but can reach as high as , making it the tallest tree in Western Australia and one of the tallest in the world. As of February 2019, the tallest known living karri is just over 80m tall. A tree south of Pemberton, known as 'The Tyrant' is 69m tall and 11.5m in girth and contains approximately 220m³ of wood in its trunk and is thought to be the largest karri by wood volume. The bark on the trunk and branches is smooth, grey to cream-coloured or pale orange, often mottled and is s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa Named By Hampton Wildman Parker
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Amphibian Genera
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

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 '' Geocrinia 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'' (Motorbik ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Least Concern
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the "Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15636) in the IUCN database still use the code "LR/lc", which indicates they have not been re-evaluate ...

Pseudophryne
''Pseudophryne'' is a genus of small myobatrachid frogs. All of these frogs are small terrestrial frogs, and as such, most species are commonly called toadlets (''pseudo-'' meaning deceptive, ''phryne'' meaning toad). The genus comprises thirteen species, ten from eastern Australia, and three from Western Australia Western Australia (commonly abbreviated as WA) is a state of Australia occupying the western percent of the land area of Australia excluding external territories. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to th .... Species within the genus ''Pseudophryne'' lay their eggs on moist ground. The tadpoles develop within the eggs, and once they reach hatching size, will become dormant. Once sufficient rain occurs to flush the eggs into a creek or river, the eggs will hatch and release tadpoles into the water. Many of the species within this genus have the ability to form hybrids. Species The following species are recognised in the genu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jarrah
''Eucalyptus marginata'', commonly known as jarrah, djarraly in Noongar language and historically as Swan River mahogany, is a plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a tree with rough, fibrous bark, leaves with a distinct midvein, white flowers and relatively large, more or less spherical fruit. Its hard, dense timber is insect resistant although the tree is susceptible to dieback. The timber has been utilised for cabinet-making, flooring and railway sleepers. Description Jarrah is a tree which sometimes grows to a height of up to with a diameter at breast height (DBH) of , but more usually with a DBH of up to . Less commonly it can be a small mallee to 3 m. Older specimens have a lignotuber and roots that extend down as far as . It is a stringybark with rough, greyish-brown, vertically grooved, fibrous bark which sheds in long flat strips. The leaves are arranged alternately along the branches, narrow lance- ...

Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tympanum (zoology)
The tympanum is an external hearing structure in animals such as mammals, birds, some reptiles, some amphibians and some insects. Using sound, vertebrates and many insects are capable of sensing their prey, identifying and locating their predators, warning other individuals, and locating potential mates and rivals by hearing the intentional or unintentional sounds they make. In general, any animal that reacts to sounds or communicates by means of sound, needs to have an auditory mechanism. This typically consists of a membrane capable of vibration known as the tympanum, an air-filled chamber and sensory organs to detect the auditory stimuli. Anurans In frogs and toads, the tympanum is a large external oval shape membrane made up of nonglandular skin. It is located just behind the eye. It does not process sound waves; it simply transmits them to the inner parts of the amphibian's ear, which is protected from the entry of water and other foreign objects. A frog's ear drum works ...
