Chalcorana Scutigera
''Chalcorana scutigera'' is a species of "true frog" in the family Ranidae. However, it is a poorly known species that might actually be Synonym (taxonomy), synonymous with ''Polypedates leucomystax''. It is endemic to Peninsular Thailand. Common names Haut Sanuk frog and yellow trea frog have been coined for it. Description ''Chalcorana scutigera'' was species description, described based on a single specimen, the holotype, which is a male measuring in snout–vent length. The specimen was yellow when observed alive but turned paler when caught, with the yellow colour almost disappearing. The snout is rounded. The Tympanum (anatomy), tympanum is very distinct. The fingers and toes are slender and bear well-developed discs; the toes are broadly webbed. Habitat and conservation Habitat requirements of ''Chalcorana scutigera'' are unknown, but it presumably breeds in water. The holotype was caught from a "cactus". Threats to it are unknown, and it is also unknown whether it occurs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lars Gabriel Andersson
Lars Gabriel Andersson (22 February 1868 – 13 February 1951) was a Swedish schoolteacher and herpetologist. He studied at Uppsala University and earned his PhD in 1909. During his long career he taught classes at several schools in and near Stockholm. In 1894–95 and from 1897 to 1902 he worked as an assistant in the vertebrate department at the Naturhistoriska riksmuseet in Stockholm. Taxa With zoologist Einar Lönnberg he described the following herpetological species: * ''Aipysurus tenuis'', 1913 * '' Atractaspis engdahli'', 1913 * ''Eulamprus brachyosoma'', 1915. * '' Eulamprus tympanum'', 1915 * '' Gastrotheca microdiscus'', (Andersson in Lönnberg and Andersson, 1910). * ''Glaphyromorphus mjobergi'', 1915 * ''Strophurus taeniatus'', 1913. On his own, he described: * '' Didynamipus sjostedti'', 1903 Works by Andersson that have been published in English * "Catalogue of Linnean type-specimens of snakes in the Royal Museum in Stockholm", 1899. * "Catalogue of Linnean ...

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
True Frog
True frogs is the common name for the frog family Ranidae. They have the widest distribution of any frog family. They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa (including Madagascar), and Asia. The Asian range extends across the East Indies to New Guinea and a single species (the Australian wood frog (''Hylarana daemelii'')) has spread into the far north of Australia. Typically, true frogs are smooth and moist-skinned, with large, powerful legs and extensively webbed feet. The true frogs vary greatly in size, ranging from small—such as the wood frog (''Lithobates sylvatica'')—to large. Many of the true frogs are aquatic or live close to water. Most species lay their eggs in the water and go through a tadpole stage. However, as in most families of frogs, there is large variation of habitat within the family. There are also arboreal speci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...

Polypedates Leucomystax
''Polypedates'' is a genus of frogs in the family Rhacophoridae, the shrub frogs and Paleotropic tree frogs. They belong to subfamily Rhacophorinae. Members of this genus are collectively known as whipping frogs. They occur in eastern and southern Asia. The delimitation of ''Polypedates'' versus the related ''Rhacophorus'' has been difficult. In former times, the present genus was often entirely included in ''Rhacophorus''. However, molecular phylogenetic studies support the recognition of both genera. ''Polypedates'' + ''Taruga'' are considered to be the sister taxon of '' Feihyla'' + ''Rhacophorus''. Species The following species are recognised in the genus ''Polypedates'', with new species still being described on a regular basis: * '' Polypedates assamensis'' Mathew & Sen, 2009 * '' Polypedates bengalensis'' Purkayastha et al., 2019 * '' Polypedates braueri'' (Vogt, 1911) – White-lipped treefrog or Java treefrog * ''Polypedates colletti'' (Boulenger, 1890) – Collett's ...

Endemic
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peninsular Thailand
Southern Thailand, Southern Siam or Tambralinga is a southernmost cultural region of Thailand, separated from Central Thailand region by the Kra Isthmus. Geography Southern Thailand is on the Malay Peninsula, with an area of around , bounded to the north by Kra Isthmus, the narrowest part of the peninsula. The western part has highly steep coasts, while on the east side river plains dominate. The largest river of the south is the Tapi in Surat Thani, which together with the Phum Duang in Surat Thani drains more than , more than 10 percent of the total area of southern Thailand. Smaller rivers include the Pattani, Saiburi, Krabi, and the Trang. The biggest lake of the south is Songkhla Lake ( altogether). The largest artificial lake is the Chiao Lan (Ratchaprapha Dam), occupying of Khao Sok National Park in Surat Thani. The total forest area is or 24.3 percent of provincial area. Running through the middle of the peninsula are several mountain chains, with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessaril ...

Tympanum (anatomy)
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 wo ...

Chalcorana
''Chalcorana'' is a genus of frogs in the family Ranidae, "true frogs". They are found in Southeast Asia, from Thailand to Malay Peninsula and the Sunda Islands. Taxonomy ''Chalcorana'' was originally introduced as a subgenus of ''Rana''. It was often included in the then-diverse genus ''Hylarana'', until Oliver and colleagues revised the genus in 2015, delimiting ''Hylarana'' more narrowly and elevating ''Chalcorana'' to genus rank. Description ''Chalcorana'' are small to medium-sized frogs with a long head and bullet-shaped body. The upper lip is usually white. The limbs and the body are gracile. There are many accessory body glands. The dorsum is shagreened and with fine mottling. There may be small, round glands which may be tipped with spicules. The dorsolateral folds are thin or consist of a line of warts. The diagnostic characters of ''Chalcorana'' are the first finger being no longer than the second one, large finger discs (at least twice the finger width), and humeral ...
