Rana Huanrenensis
The Huanren frog (''Rana huanrensis'') is a species of true frog found in East Asia. It was originally believed to be endemic to Huanren County, Liaoning, China, but was later also found in South Korea; it is presumed to be present in North Korea, as well. It is closely related to the Dybowski's frog, ''Rana dybowskii'', and specimens collected before 1991 were incorrectly identified as that species. Distinguishing factors include the absence of a vocal sac. The Huanren frog is found in and around rivers and streams in hilly terrain. The type locality in Huanren is above sea level, and specimens from Korea have also only been found at altitudes over . Specimens from South Korea have been collected in the provinces of Gangwon-do, Gyeongsangbuk-do, and eastern Gyeonggi-do Gyeonggi-do (, ) is the most populous province in South Korea. Its name, ''Gyeonggi'', means "京 (the capital) and 畿 (the surrounding area)". Thus, ''Gyeonggi-do'' can be translated as "Seoul and the ...

Type Locality (biology)
In biology, a type is a particular specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally attached. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the International Code of Nomenclature for algae, fungi, and plants (ICN), the scientific name of every taxon is almost a ...

Amphibians Of Korea
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decline ...

Rana (genus)
''Rana'' 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. Distribution and habitat 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 produce up to 20,000 at one time. ...

Gyeonggi-do
Gyeonggi-do (, ) is the most populous province in South Korea. Its name, ''Gyeonggi'', means "京 (the capital) and 畿 (the surrounding area)". Thus, ''Gyeonggi-do'' can be translated as "Seoul and the surrounding areas of Seoul". Seoul, the nation's largest city and capital, is in the heart of the area but has been separately administered as a provincial-level ''special city'' since 1946. Incheon, the nation's third-largest city, is on the coast of the province and has been similarly administered as a provincial-level ''metropolitan city'' since 1981. The three jurisdictions are collectively referred to as '' Sudogwon'' and cover , with a combined population of 25.5 million—amounting to over half of the entire population of South Korea. History Gyeonggi-do has been a politically important area since 18 BCE, when Korea was divided into three nations during the Three Kingdoms period. Ever since King Onjo, the founder of Baekje (one of the three kingdoms), founded the governm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gyeongsangbuk-do
North Gyeongsang Province ( ko, 경상북도, translit=Gyeongsangbuk-do, ) is a province in eastern South Korea. The province was formed in 1896 from the northern half of the former Gyeongsang province, and remained a province of Korea until the country's division in 1945, then became part of South Korea. Daegu was the capital of North Gyeongsang Province between 1896 and 1981, but has not been a part of the province since 1981. In 2016, the provincial capital moved from Daegu to Andong. The area of the province is , 19.1 percent of the total area of South Korea. Geography and climate The province is part of the Yeongnam region, on the south by Gyeongsangnam-do, on the west by Jeollabuk-do and Chungcheongbuk-do Provinces, and on the north by Gangwon-do Province. During the summer, North Gyeongsang Province is perhaps the hottest province in South Korea. This is helped by the fact that the province is largely surrounded by mountains: the Taebaek Mountains in the east and the S ...

Gangwon-do (South Korea)
Gangwon Province is a province of South Korea, with its capital at Chuncheon. It is bound on the east by the Sea of Japan, and borders Gyeonggi Province to its west, North Gyeongsang Province and North Chungcheong Province to its south, and the Military Demarcation Line to the north, separating it from North Korea's Kangwŏn Province. Before the division of Korea in 1945 Gangwon and Kangwŏn Provinces formed a single province. Pyeongchang County in Gangwon hosted the 2018 Winter Olympics and 2018 Winter Paralympics, with Gangwon hosting the 2024 Winter Youth Olympics. History Gangwon-do was one of the Eight Provinces of Korea during the Joseon Dynasty, formed in 1395, deriving its name from the names of the principal cities of Gangneung () and the provincial capital Wonju (). In 1895 Gangwon-do was replaced by the Districts of Chuncheon (''Chuncheon-bu;'' ) in the west and Gangneung (''Gangneung-bu;'' ) in the east, with Wonju becoming a part of Chungju District.

Vocal Sac
The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example; The vocal sac is open to the mouth cavity of the frog, with two slits on either side of the tongue. To call, the frog inflates its lungs and shuts its nose and mouth. Air is then expelled from the lungs, through the larynx, and into the vocal sac. The vibrations of the larynx emits a sound, which resonates on the elastic membrane of the vocal sac. The resonance causes the sound to be amplified and allows the call to carry further. Muscles within the body wall force the air back and forth between the lungs and vocal sac. Development The development of the vocal sac is different in most species, however they mostly follow the same process. The d ...

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] |
Dybowski's Frog
Dybowski's frog (''Rana dybowskii'') is a species of true frog found in Northeast Asia. It is found in the Russian Far East, the Korean Peninsula, and the Japanese island of Tsushima. It may also exist in northeastern China, but this has not been confirmed. The Dybowski's frog is fairly tolerant of human disturbance; however, it has been threatened across portions of its range due to heavy collection for use in traditional Chinese medicine. It breeds in slow-moving and stagnant water, and when not breeding, is most commonly found in woodlands. The species covers a wide range of altitudes, from sea level to 900 m, and possibly higher. Adult Dybowski's frogs have a body length of . The head and body are relatively broad; the skin is generally smooth, but with some small protuberances along the back. The male has a pair of vocal sacs which are used during the mating season. The back is largely tan to dark brown, and the belly is white. References * * {{Taxonbar, from=Q30 ...
