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 ...

Ye Changyuan
Ye Changyuan (born 1936) is an amphibian expert in the People's Republic of China and a researcher at the Amphibian and Reptile Laboratory of the Chengdu Institute of Biology, Chinese Academy of Sciences. Biography In 1956, Ye Changyuan was admitted to the Animal Husbandry Major of Sichuan Agricultural College (now Sichuan Agricultural University). After graduation in 1961, she entered the Institute of Agricultural Biology, Sichuan Branch of the Chinese Academy of Sciences (now the Chengdu Institute of Biology, Chinese Academy of Sciences) and began amphibian research. Her husband Fei Liang is a research partner and a fellow amphibian expert. They met at the university and married in 1963. She initially served as assistant to amphibian research experts Liu Chengzhao and Hu Shuqin. Ye Changyuan suspended her scientific field research work in 1964 after becoming pregnant. To continue her work, Ye Changyuan and her husband cooperated to meet their own individual work needs. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
