Pelodryadinae
Pelodryadinae, also known as Australian treefrogs (although not all members are arboreal), is a subfamily of frogs found in the region of Australia and New Guinea, and have also been introduced to New Caledonia, Guam, New Zealand, and Vanuatu. The subfamily is thought to be the sister group to the leaf frogs (Phyllomedusinae), a subfamily of arboreal frogs known from the Neotropics. The common ancestor of both subfamilies is thought to have lived in early Cenozoic South America, with the two subfamilies diverging from one another during the Eocene. The ancestors of the subfamily Pelodryadinae likely invaded Australasia via Antarctica, which at the time was not yet frozen over, thus was hospitable for the dispersing frogs. The clade comprising both subfamilies is sister to the Hylinae, from which they diverged in the early Paleogene. Classification The subfamily contains 222 species in three genera: * ''Litoria'' (102 species) * ''Nyctimystes'' (44 species) * ''Ranoidea'' (71 sp ...

"Litoria" Castanea
"''Litoria''" ''castanea'', also known as the yellow-spotted tree frog, New England swamp frog, tablelands bell frog, or yellow-spotted bell frog, is a species of frog in the subfamily Pelodryadinae. It is a critically endangered species of frog that is endemic to south-eastern Australia. Taxonomy The placement of "''Litoria''" ''castanea'' is considered as ''incertae sedis'' within the subfamily Pelodryadinae and its temporary inclusion in the genus ''Litoria'' is indicated by the quotation marks around the genus name. It is presumed that it will ultimately be returned to the genus ''Ranoidea'' along with the other members of the former ''Litoria aurea'' species complex. Description "''Litoria''" ''castanea'' is distinguished by cream markings on its thighs. Its overall colour is pale green and the dark to black spots are highlighted by the bronze patches. The toes are entirely webbed. Distribution and habitat "''Litoria''" ''castanea'' is endemic to the New England Tablela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange-thighed Frog
The orange-thighed frog (''Ranoidea xanthomera'') is a species of tree frog native to a small area of tropical northern Queensland, Australia. It is a green frog with distinctly orange eyes, and is very similar in appearance to the red-eyed tree frog. Description The orange-thighed frog is a medium-sized tree frog, reaching a length of . It is a slender frog, with a thin body, flat head, and large eyes, which are orange in colour. It has a green dorsal surface, with bright yellow feet and vocal sac, and a yellow band down its flank. The inner surfaces of its legs are yellow, and the outer surfaces are green. It is distinguished, physically, from the red-eyed tree frog by the presence of bright-orange thighs; the red-eyed tree frog has mauve thighs. Ecology and behaviour Male orange-thighed frogs congregate around still ponds, and call from low branches, or the edges of the water. The call is a long "aaa-rk", followed by a soft trill. They call after heavy monsoon rains. The ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ranoidea (genus)
''Ranoidea'' is a genus of frogs in the subfamily Pelodryadinae. They are found in Australia, New Guinea, and two nearby groups of islands: the Maluku Islands, and the Louisiade Archipelago. The circumscription of this taxon is still controversial. Taxonomy Species in this genus were until recently placed in the then-paraphyletic genus ''Litoria''; many of them had been placed in even larger ''Hyla'' before. However, in 2016 Duellman and colleagues split ''Litoria'' into several genera. The systematic and taxonomic conclusions based on Duellman ''et al.'' should be treated with caution, because 78.9% of individuals (397/503) used in the concatenated analyses had less than half of the gene sequences available for the 19 genes used. Missing data can be problematic in phylogenetic analyses (e.g.) and lead to erroneous conclusions about systematic relationships. Additionally, there is no mention of checking for base-composition bias amongst taxa (non-stationarity), which can also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phyllomedusinae
Phyllomedusinae is a subfamily of hylid tree frogs found in the Neotropics commonly called leaf frogs. Formerly, they were often considered as their own family, Phyllomedusidae. The subfamily is considered to be the sister group to the Australian treefrogs (Pelodryadinae), a subfamily of frogs known from Australia and New Guinea, despite being very geographically separated from them. The common ancestor of both subfamilies is thought to have lived in early Cenozoic South America, where the Phyllomedusinae still live, with the two families diverging from one another during the Eocene. The ancestors of Pelodryadinae likely colonized Australasia from South America via Antarctica, which at the time was not yet frozen over. The clade comprising both subfamilies is sister to the Hylinae, from which they diverged in the early Paleogene. Taxonomy The subfamily Phyllomedusidae contains the following genera: * ''Agalychnis'' (14 species) * ''Callimedusa'' (six species) * ''Cruziohyla' ...

Nyctimystes
''Nyctimystes'' is a genus of tree frogs in the subfamily Pelodryadinae of the family Hylidae. They are principally Papuan species, but also inhabit islands in the Moluccas. All species in this genus have one distinct feature that separates them from other species in the family, the lower eyelid is marked with pattern of lines, veins, or dots. This feature presumably acts as camouflage when the frogs are at rest during the day. Species of this genus inhabit tropical The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to ... or subtropical montane rainforest. The eggs are large and are laid on submerged objects in fast-flowing creeks and streams (not all species of this genus have been recorded as doing this, although it is assumed). The tadpoles have large sucker-mouths and their body s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Litoria Microbelos
The javelin frog (''Litoria microbelos'') is a species of frog in the subfamily Pelodryadinae, that is endemic to Australia. Its natural habitat In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical ...s are subtropical or tropical dry lowland grassland, swamps, and intermittent freshwater marshes. Description The javelin frog is the smallest known tree frog in Australia, with males reaching and females in length. Colours are typically brown with a light-brown dorsal surface, dark-brown lateral stripes and light, almost white, ventral surface. A white stripe runs along the lip and along the side of the frog.

Paleogene
The Paleogene ( ; British English, also spelled Palaeogene or Palæogene; informally Lower Tertiary or Early Tertiary) is a geologic period, geologic period and system that spans 43 million years from the end of the Cretaceous Period million years ago (annum, Mya) to the beginning of the Neogene Period Mya. It is the beginning of the Cenozoic Era of the present Phanerozoic Eon. The earlier term Tertiary Period was used to define the span of time now covered by the Paleogene Period and subsequent Neogene Period; despite no longer being recognised as a formal stratigraphy, stratigraphic term, 'Tertiary' is still widely found in earth science literature and remains in informal use. Paleogene is often abbreviated "Pg" (but the United States Geological Survey uses the abbreviation PE for the Paleogene on the Survey's geologic maps). During the Paleogene, evolution of mammals, mammals diversified from relatively small, simple forms into a large group of diverse animals in the wake of ...
