Rana (genus)
''Rana'' (derived from Latin ''rana'', meaning 'frog') is a genus of frogs commonly known as the Holarctic true frogs, pond frogs or brown frogs. Members of this genus are found through much of Eurasia and western North America. Many other genera were formerly included here. These true frogs are usually largish species characterized by their slim waists and wrinkled skin; many have thin ridges running along their backs, but they generally lack "warts" as in typical toads. They are excellent jumpers due to their long, slender legs. The typical webbing found on their hind feet allows for easy movement through water. Coloration is mostly greens and browns above, with darker and yellowish spots. Behavior Many frogs in this genus breed in early spring, although subtropical and tropical species may breed throughout the year. Males of most of the species are known to call, but a few species are thought to be voiceless. Females lay eggs in rafts or large, globular clusters, and can pro ...

Early Miocene
The Early Miocene (also known as Lower Miocene) is a sub-epoch of the Miocene epoch (geology), Epoch made up of two faunal stage, stages: the Aquitanian age, Aquitanian and Burdigalian stages. The sub-epoch lasted from 23.03 ± 0.05 annum, Ma to 15.97 ± 0.05 Ma (million years ago). It was preceded by the Oligocene epoch. As the climate started to get cooler, the landscape started to change. New mammals evolved to replace the extinct animals of the Oligocene epoch. The first members of the hyena and weasel family started to evolve to replace the extinct ''Hyaenodon'', entelodonts and bear-dogs. The chalicotheres survived the Oligocene epoch. A new genus of entelodont called ''Daeodon'' evolved in order to adapt to the new habitats and hunt the new prey animals of the Early Miocene epoch; it quickly became the top predator of North America. But it became extinct due to competition from ''Amphicyon'', a newcomer from Eurasia. ''Amphicyon'' bested ''Daeodon'' because the bear-dog's la ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanguirana
''Sanguirana'' is a genus of true frogs (family Ranidae) found in the Malay Archipelago, including the Philippines, the Maluku Islands, Sulawesi, and Seram. ''Sanguirana'' was first introduced as a sub-genus of ''Rana Rana may refer to: Astronomy * Rana (crater), a crater on Mars * Delta Eridani or Rana, a star Films * Rana (2012 film), an Indian Kannada-language action drama * Rana, a 1998 Telugu-language action film directed by A.

All species, except the more recently described '' Sanguirana aurantipunctata'' and '' Sanguirana acai'', were originally included in ''Rana''; more recently, they have been placed in genus '' Hylarana''.

Pelophylax
''Pelophylax'' is a genus of true frogs widespread in Eurasia, with a few species ranging into northern Africa. This genus was erected by Leopold Fitzinger in 1843 to accommodate the green frogs of the Old World, which he considered distinct from the brown pond frogs of Carl Linnaeus' genus '' Rana''. They are also known as water frogs, as they spend much of the summer living in aquatic habitat; the pond frogs can be found more often, by comparison, on dry land, as long as there is sufficient humidity. Yet there are species of Eurasian green frogs – the Central Asian '' P. terentievi'', or the Sahara frog (''P. saharicus'') – which inhabit waterholes in the desert. Systematics and taxonomy Most authors throughout the 19th and 20th century disagreed with Fitzinger's assessment. The green frogs were included again with the brown frogs, in line with the tendency to place any frog similar in habitus to the common frog (''R. temporaria'') in ''Rana''. That ge ...

Odorrana
''Odorrana'', commonly known as odorous frogs, is a genus of true frogs (Ranidae) from East Asia and surrounding regions. Many of these frogs inhabit fast-flowing mountain streams, and they typically have a remarkably pointed snout, as evidenced by common names like tip-nosed frog and scientific names like ''nasica'' or ''nasutus'' ("with a nose"). Systematics and taxonomy ''Odorrana'' has a confusing taxonomic and systematic history. Most species placed here were initially placed in ''Rana''. Some were considered to belong in '' Amolops'' and '' Huia'' instead, and yet again others were separated as ''Eburana''. The most extreme proposal was to merge ''Odorrana'' into ''Huia''.Cai ''et al.'' (2007), Stuart (2008) In the early 21st century, molecular phylogenetic studies established that the systematic confusion was due to widespread convergent evolution between ''Amolops'', ''Huia'' and ''Odorrana'', which actually represent quite distinct lineages of Raninae. This necessitated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lithobates
''Lithobates'', commonly known as the bullfrogs, is a genus of true frogs, of the family Ranidae. The name is derived from '' litho-'' (stone) and the Greek ' (, one that treads), meaning one that treads on rock, or rock climber. As presently defined, it includes many of eastern North America's most familiar aquatic frog species, including the American bullfrog, green frog, and the leopard frogs. Systematics The name was defined by Hillis and Wilcox (2005) for a subgenus of four Central and South American frogs within the genus ''Rana''. The subgenus was subsequently expanded to seven species in Central and South America in a systematic revision of the genus ''Rana''. The name was previously used by Frost ''et al.'' as a separate genus of ranid frogs that included most of the North American frogs traditionally included in the genus ''Rana'',Frost, Darrel R.

Hylarana
''Hylarana'', commonly known as golden-backed frogs, is a genus of true frogs found in tropical Asia. It was formerly considered highly diverse, containing around 84 to 96 valid species, but taxonomic revision resulted in a major change in the contents of the genus, recognizing just four species. Description ''Hylarana'' are small to large-sized frogs. Males have an average snout-vent length of , while females range from . The nares (nostrils) are oval in shape and covered by a flap of skin. The tympanum is visible but is not covered by a supratympanic fold. Vomerine teeth and a pineal ocellus (parietal eye) are present. The toes are webbed, but the fingers are not. Distribution Former members of the genus ''Hylarana'' ranged from Sri Lanka to the Western Ghats of India, through Nepal and southern China and Taiwan, down to Southeast Asia to the Philippines and Papua New Guinea, in Northern Australia, and tropical Africa. Following taxonomic revisions, the genus distribution ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glandirana
''Glandirana'' is a genus of true frogs (family Ranidae) found in the East Asia (eastern China, Korea, Japan, and possibly Primorsky Krai in the Russian Far East). The name means ‘glandular frog’. Taxonomy and systematics The genus ''Glandirana'' was split off from ''Rana (genus), Rana''. All species, except the more recently described ''Glandirana susurra'' and ''Glandirana reliquia'', were originally included in ''Rana''; some of them were placed in genus ''Rugosa'', which is now synonymized with ''Glandirana''. Although the monophyly of the genus has been questioned, it is supported by recent molecular work. ''Glandirana'' is considered likely to be a sister taxon of the genus ''Hylarana''. Species The following species are recognised in the genus ''Glandirana'': * ''Glandirana emeljanovi'' (Nikolskii, 1913) * ''Glandirana minima'' (Ting and T'sai, 1979) * ''Glandirana reliquia'' Shimada, Matsui, Ogata, and Miura, 2022 * ''Glandirana rugosa'' (Temminck and Schlegel, 1838) ...
