Amolops Dafangensis
''Amolops'' (commonly known as cascade frogs or sucker frogs) is a genus of true frogs (family Ranidae) native mainly to eastern and south-eastern Asia. These frogs are closely related to such genera as ''Huia'', '' Meristogenys'', ''Odorrana'', ''Pelophylax'' and ''Rana'', but still form a distinct lineage among the core radiation of true frogs.Cai ''et al.'' (2007), Stuart (2008) They are commonly known as "torrent frogs" after their favorite habitat - small rapid-flowing mountain and hill streams - but this name is used for many similar-looking frogs regardless of whether they are loosely related. Several species are highly convergent with other Ranidae "torrent frogs". '' A. archotaphus'' and its relatives for example very much resemble '' Odorrana livida''. In another incidence of convergent evolution yielding adaptation to habitat, the tadpoles of ''Amolops'', ''Huia'', ''Meristogenys'' as well as ''Rana sauteri'' have a raised and usually well-developed sucker on their ...

Convergent Evolution
Convergent evolution is the independent evolution of similar features in species of different periods or epochs in time. Convergent evolution creates analogous structures that have similar form or function but were not present in the last common ancestor of those groups. The cladistic term for the same phenomenon is Cladogram#Homoplasies, homoplasy. The recurrent evolution of flight is a classic example, as flying pterygota, insects, birds, pterosaurs, and bats have independently evolved the useful capacity of flight. Functionally similar features that have arisen through convergent evolution are ''analogous'', whereas ''homology (biology), homologous'' structures or traits have a common origin but can have dissimilar functions. Bird, bat, and pterosaur wings are analogous structures, but their forelimbs are homologous, sharing an ancestral state despite serving different functions. The opposite of convergence is divergent evolution, where related species evolve different trai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amolops Ailao
''Amolops ailao'', the Ailao cascade frog, is a species of true frog found on Mt. Ailao in the Yunnan Province, China. Description There is much variation in within the species. They show sexual dimorphism in that the female is bigger than the male. It is morphologically similar to its sister taxon ''Amolops ottorum''.

Amolops Afghanus
Kachin torrent frog (''Amolops afghanus'') is a species of true frog native to Myanmar. Description Kachin torrent frog is an obscure species and not much is known about it. However, from preserved specimens and written descriptions, it is known that it is a medium-sized, sometimes slender frog with a broad head. According to the original author, Albert Günther, the skin is smooth, but observations from iNaturalist depict multiple individuals with small knobs on the dorsal side. Furthermore, they are dark green with a dark, mottled pattern on their dorsal side. They also have dark, mottled, or clear bands on their limbs, which vary by observation. The ventral side appears to be light. The species shows clear sexual dimorphism in size. Females have an SVL of around , while males have an SVL of around .

Amolops Marmoratus
''Amolops marmoratus'' is a species of ranid frog found in Asia. Its common names include marbled sucker frog, marbled cascade frog, Pegu torrent frog, and many others. The taxonomic status of many populations formerly assigned to this species is uncertain. Description ''Amolops marmoratus'' shows a pronounced sexual dimorphism in size: males grow to snout-vent length of and females to . It is a relatively small species among ''Amolops''. Distribution and habitat ''Amolops marmoratus'' is only known with certainty from Myanmar and likely from northern Thailand, though it may occur more widely. For example, International Union for Conservation of Nature (IUCN), using a less stringent delineation of the species, reported the species also from Bangladesh, Bhutan, China, India, and Nepal. While IUCN in its assessment in 2004 considered ''Amolops marmoratus'' to be of "Least Concern A least-concern species is a species that has been evaluated and categorized by the Internationa ...

Phetchaburi
Phetchaburi (, ) or Phet Buri () is a town ('' thesaban mueang'') in southern Thailand, capital of Phetchaburi Province. In Thai, Phetchaburi means "city of diamonds" (''buri'' meaning "city" in Sanskrit). It is approximately 160 km south of Bangkok, at the northern end of the Thai peninsula. As of 2005, the town had a population of 26,181 and covers the two ''tambon'' Tha Rap and Khlong Krachaeng. The Phetchaburi River runs through the middle of the city. The region is mostly flat, save for a single hill (called ''Khao Wang'') on the outskirts of town. The royal palace named Phra Nakhon Khiri and one of the many wats are on top of Khao Wang. The hill and town is the site of an annual festival, called the Phra Nakhon Khiri Fair. It lasts for eight days in early February and includes a sound and light show and classical Thai dance. The official city flower is the leelowadee flower or frangipani. Phetchaburi is known for its traditional Thai desserts. The most well-known ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

DNA Sequence
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence represents genetic information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as "prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staurois
''Staurois'' is a small genus of minuscule true frogs. Most species in the genus are restricted to Borneo, but two species are from the Philippines.Arifin, U., D. T. Iskandar, D. P. Bickford, R. M. Brown, R. Meier, and S. N. Kutty. (2011). Phylogenetic relationships within the genus Staurois (Anura, Ranidae) based on 16S rRNA sequences. Zootaxa 2744: 39–52 This genus is a quite ancient member of the true frog family, Ranidae. They are typically found in or near rapidly flowing, small rocky streams, and are sometimes known as splash frogs or foot-flagging frogs. The latter name refers to their unusual behavior of conspicuously waving their hindlegs and feet, as a way of signalling other members of the species.Grafe, Preininger, Sztatecsny, Kasah, Dehling, Proksch & Höd (2012).

Rana Sauteri
''Rana sauteri'' is a species of true frog endemic to Taiwan. It inhabits low-altitude hill forests and the associated streams. It is an endangered species threatened by habitat loss due to agriculture and infrastructure development. Common names recorded for ''Rana sauteri'' include Kanshirei Village frog, Taiwan groove-toed frog, Sauter's brown frog, and Taiwan pseudotorrent frog. Taxonomy ''Rana sauteri'' was first described in 1909 by George Albert Boulenger on the basis of specimens collected on Taiwan by one H. Sauter. Boulenger noted resemblances to '' Rana japonica'' and ''Rana mortenseni'' (now '' Hylarana mortenseni'') and thought the species bridged part of the gap between '' Hylorana'' (now spelled ''Hylarana'') and the ''Rana temporaria'' group of species. In 1920, however, Boulenger placed the species in the subgenus ''Hylorana'' of the genus ''Rana''. In 1991, Fei and colleagues placed it in a new genus ''Pseudorana'' together with ''Rana sangzhiensis'' and '' Rana ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tadpole
A tadpole or polliwog (also spelled pollywog) is the Larva, larval stage in the biological life cycle of an amphibian. Most tadpoles are fully Aquatic animal, aquatic, though some species of amphibians have tadpoles that are terrestrial animal, terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians, such as a lateral line, gills and swimming tails. As they undergo metamorphosis, they start to develop functional lungs for breathing air, and the diet of tadpoles changes drastically. A few amphibians, such as some members of the frog family Brevicipitidae, undergo direct development i.e., they do not undergo a free-living larval stage as tadpoles instead emerging from eggs as fully formed "froglet" miniatures of the adult morphology (biology), morphology. Some other species hatch into tadpoles underneath the skin of the female adult or are kept in a pouch until after metamorphosis. Having no hard skeletons, it might be expected that tadpole fos ...
