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] |
Southwest Australia
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna. The region is also known as the Southwest Australia Global Diversity Hotspot. Geography The region includes the Mediterranean forests, woodlands, and scrub ecoregions of Western Australia. The region covers 356,717 km2, consisting of a broad coastal plain 20–120 kilometres wide, transitioning to gently undulating uplands made up of weathered granite, gneiss and laterite. Bluff Knoll in the Stirling Range is the highest peak in the region, at 1,099 metres (3,606 ft) elevation. Desert and xeric shrublands lie to the north and east across the centre of Australia, separating Southwest Australia from the other Mediterranean and humid-climate regions of the continent. Climate The region has a wet-winter, dry-summer Mediterranean climate, one of five such regions in the worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kununurra, Western Australia
Kununurra is a town in far northern Western Australia located at the eastern extremity of the Kimberley (Western Australia), Kimberley approximately from the border with the Northern Territory. Kununurra was initiated to service the Ord River Irrigation Scheme. It is located on the traditional lands of the Miriwoong, an Aboriginal Australian people. Kununurra is the largest town in Western Australia north of Broome, Western Australia, Broome, with the closest town being Wyndham, Western Australia, Wyndham, away. Kununurra is from Perth, Western Australia, Perth via the Great Northern Highway. The town is situated among the scenic hills and ranges of the far north-east Kimberley region, having an abundance of fresh water, conserved by the Ord River Diversion dam and the main Ord River Dam. The tropical agriculture crops grown in the Ord River Irrigation Area (ORIA) have changed over the years. Tourism and mining have also become important to the local economy. History ...

Metacrinia
''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 ...

Geocrinia
''Geocrinia'' is a genus of frogs in the family Myobatrachidae. These frogs are endemic to Australia. Two species are known from southeastern Australia ( Victoria and Tasmania), while one is known from southeastern Western Australia. All the species in this genus were at some point referred to as '' Crinia''. Further studies showed there was some considerable differences between this group of frogs and ''Crinia''. These differences included; a slightly sturdier body, smoother skin on the ventral surface and the greatest difference, the reproductive nature, laying the eggs outside of water. Until 2022, four other species in Western Australia Western Australia (WA) is the westernmost state of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Aust ... were also classified in this genus, but a phylogenetic study reclassified them into the new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crinia
''Crinia'' is a genus of frog, native to Australia, and part of the family Myobatrachidae. It consists of small frogs, which are distributed throughout most of Australia, excluding the central arid regions. Many of the species within this genus are physically indistinguishable, and can only be identified by their calls. They have unwebbed toes and fingers, most of the species in these genus are polymorphic - meaning that several variations of colour and skin patterning exist in a single population and all species lay their eggs in small clumps in water. The generic name ''Crinia'' likely derives from the Greek verb κρῑνω (krīnō) "to separate" as a reference to the frog's unwebbed digits, meaning "separated (toes)". Although Johann Jakob von Tschudi did not provide an etymology in 1838, he cited the frog's "free toes" (without webbing) as an important distinctive feature (most frogs have webbed feet). During the 1950s, 1960s and 1970s a lot of taxonomic work was done on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arenophryne
''Arenophryne'' is a small genus of Myobatrachidae, Myobatrachid frogs from coastal Western Australia. Common names sandhill frogs and Australian dumpy frogs have been coined for it. Both species live in sand dune habitat of the Shark Bay region of Western Australia. The two species were initially considered to be just one species, but a genetic analysis found the northern and southern populations to be distinct. Breeding occurs during the wetter winter months where adults call near the surface, and mate underground. The eggs are laid in a burrow and develop directly from eggs to frogs. Species There are two species: References {{Taxonbar, from=Q2445381 Myobatrachidae Amphibian genera Taxa named by Michael J. Tyler Amphibians of Australia ...

Notaden
''Notaden'' is a genus of burrowing ground frogs native to central and northern Australia. Their common name is Australian spadefoot toads. Description Its body is very round in shape with a short neck. Its pupils are horizontal slits. It has long arms and short, stubby legs. Its fingers lack webbing and its toes may have slight to no webbing. The skin is slightly warty and very glandular. Because of its similarity to some species of toads it is often incorrectly referred to as a toad. It excretes poisonous sticky fluid from its skin when handled. It lays eggs in chains similar to some toad species. Species There are four species in this genus: References External links Notaden, Amphibians of Australia Amphibian genera Taxa named by Albert Günther {{Neobatrachia-stub ...

Neobatrachus
''Neobatrachus'' is a genus of burrowing ground frogs native to Australia. They occur in every state except Tasmania, however this genus is absent from the far north of Australia and most of Queensland. Most of the species in this genus occur in south-western Western Australia. They are often found in arid areas and burrow underground to avoid dehydration. They are typically found in temporary claypan and flooded grassland habitats. These burrowing frogs have special genetic characteristics that help them to live in extreme environments. They stand out because some species are tetraploids instead of diploids. All species have a similar body shape, they are rounded and squat with large eyes and the pupils constrict vertically. The limbs are short and the hands are free from webbing while the feet are partially webbed. Males lack a vocal sac. Approximately 1000 eggs are laid in a chain in still water. The reproductive cycle is dependent on sufficient rainfall, an unpredictable eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnodynastes
''Limnodynastes'' (commonly known as the Australian swamp frogs) is a genus of frog native to Australia, southern New Guinea and some Torres Strait Islands. They are ground-dwelling frogs, with no toe pads. The size varies from 45 mm to 90 mm in the giant banjo frog. The webbing on the feet ranges between species, from very little, to almost complete. The tympanum is not visible in any species, except in the woodworker frog, which is sometimes classed in a separate genus ''Megistolotis''. All species construct a foam nest in which the eggs are laid. However, in south-eastern South Australia female striped marsh frog and spotted grass frog lack the flanges of skin on the hands that helps trap the air bubble and do not construct foam nest A nest is a structure built for certain animals to hold Egg (biology), eggs or young. Although nests are most closely associated with birds, members of all classes of vertebrates and some invertebrates construct nests. They may be ...

Heleioporus
''Heleioporus'' is a genus of frogs native to Australia. Of the six species in this genus, five live in south-west Western Australia Western Australia (WA) is the westernmost state of Australia. It is bounded by the Indian Ocean to the north and west, the Southern Ocean to the south, the Northern Territory to the north-east, and South Australia to the south-east. Western Aust ..., while the other one species only occurs in south-eastern Australia. All members of this genus are medium to large sized burrowing frogs with rounded heads, short bodies, bulging eyes, short limbs and the hands are free from webbing. The toes are relatively short with only a trace of fleshy webbing. A characteristic of this genus (except for ''Heleioporus eyrei'' and some ''Heleioporus psammophilus'') is the black nuptial spines that male frogs have on their first and occasionally second and third fingers. The pupil restrict to form a vertical slit and the tympanum is usually distinct. All the species ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limnodynastinae
Limnodynastidae, commonly known as the Australian ground frogs, is a family of frogs found in Australia, New Guinea, and the Aru Islands. They were formerly considered a subfamily of the Myobatrachidae, the other large radiation of terrestrial frogs in Australia, but are now considered a distinct family. Both Limnodynastidae and Myobatrachidae are thought to be the only members of the superfamily Myobatrachoidea. The earliest fossils of this group are of '' Platypectrum casca'' from the Early Eocene In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by th ....
