Hynobius Stejnegeri
The amber salamander, amber-colored salamander, tortoiseshell salamander, or Stejneger's oriental salamander (''Hynobius stejnegeri'') is a species of salamander in the family Asiatic salamander, Hynobiidae, Endemism, endemic to Japan. Its natural habitats are temperate forests and rivers. It is threatened by habitat loss. Physical characteristics As its name suggests, the external appearance is that of semitransparent blackish brown ground color, blotched with bright amber. Its ventral surface is lighter and without blotches. The amber salamander has a snout-to-vent length of 76–85 mm and a total length of 137–155 mm. However, individuals have been reported to have been nearly 200 mm in length. The head appears to be oval when viewed from above and the eyes are prominent, and a gular fold is present. It has a robust and cylindrical body with 13 to 14 costal grooves. It is similar to ''Hynobius kimurae'' in color, but has only four toes, a longer series of vomer ...

Amphibians Described In 1923
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, 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 re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Amphibians Of Japan
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hepatology
Hepatology is the branch of medicine that incorporates the study of liver, gallbladder, biliary tree, and pancreas as well as management of their disorders. Although traditionally considered a sub-specialty of gastroenterology, rapid expansion has led in some countries to doctors specializing solely on this area, who are called hepatologists. Diseases and complications related to viral hepatitis and alcohol are the main reason for seeking specialist advice. More than two billion people have been infected with hepatitis B virus at some point in their life, and approximately 350 million have become persistent carriers. Up to 80% of liver cancers can be attributed to either hepatitis B or hepatitis C virus. In terms of mortality, the former is second only to smoking among known agents causing cancer. With more widespread implementation of vaccination and strict screening before blood transfusion, lower infection rates are expected in the future. In many countries, however, overall ...

Phenological
Phenology is the study of periodic events in biological life cycles and how these are influenced by seasonal and interannual variations in climate, as well as habitat factors (such as elevation). Examples include the date of emergence of leaves and flowers, the first flight of butterflies, the first appearance of migratory birds, the date of leaf colouring and fall in deciduous trees, the dates of egg-laying of birds and amphibia, or the timing of the developmental cycles of temperate-zone honey bee colonies. In the scientific literature on ecology, the term is used more generally to indicate the time frame for any seasonal biological phenomena, including the dates of last appearance (e.g., the seasonal phenology of a species may be from April through September). Because many such phenomena are very sensitive to small variations in climate, especially to temperature, phenological records can be a useful proxy for temperature in historical climatology, especially in the study of ...

Yatsushiro Sea
The , which is also called the , is a shallow semi-enclosed inland sea separating the island of Kyūshū from the Amakusa Islands. It lies mostly within Kumamoto Prefecture and at the southern end of the sea it also borders Kagoshima Prefecture. To the north is the Ariake Sea; to the south, the East China Sea. Cities of note that lie on the Yatsushiro Sea include Yatsushiro itself and Minamata. Mercury pollution The sea was heavily polluted with mercury during the 1950s and 1960s from the Chisso Corporation's chemical factory in Minamata.Yoshida 2006. This highly toxic chemical bioaccumulated in shellfish and fish in the Yatsushiro Sea which, when eaten by the local populace, gave rise to Minamata disease. The pollution disease was responsible for the deaths and disabling of thousands of residents, all around the Yatsushiro Sea. The marine ecosystem was also extensively damaged.

Aso Volcano
Aso caldera (also known as Asosan, the Aso Volcano or Mount Aso, although the later term usually is used related to its currently active vents) is a geographical feature of Kumamoto Prefecture, Japan. It stretches 25 kilometers north to south and 18 kilometers east to west. The central core "Aso Gogaku" is the five major mountains in the area. Aso valley (Asodani) runs along the northern base of Mount Aso and Nango valley (Nangodani) along the south. According to research of caldera sediment, lakes used to exist in these valleys. The dried up lake areas have come to be called Old Aso Lake, Kugino Lake, and Aso Valley Lake. The Kikuchi, Shirakawa and Kurokawa rivers now drain the caldera. Geology Within the caldera are more than 17 cones. The central "Aso Gogaku" group of volcanoes are Takadake (Mount Taka) at , Nekodake at , Nakadake (Mount Naka) at , Kijimadake at and Eboshidake at . These are higher than the caldera rim itself that towards the south west is high. Other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
