Vallonia Tenuilabris
''Vallonia tenuilabris'' is a species of very small, air-breathing land snail that is a terrestrial pulmonate gastropod mollusk or micromollusk in the family Valloniidae. Distribution ''Vallonia tenuilabris'' was described for the first time in the loess of Wiesbaden, Germany. It is only in the past few decades that its recent occurrence in Central Asia has been recognised. Recent distribution of ''Vallonia tenuilabris'' include: * Central Asian highlands (Altai Mountains, Tien Shan, Pamir Mountains and Himalayas) * Northern Mongolia * from the Baikal region into Northern Asia, from Siberia to Altai, Karakorum and Yenisei. * North-eastern and north China including Xinjiang and Tibet."Species summary for ''Vallonia tenuilabris''" [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Pamir Mountains
The Pamir Mountains are a mountain range between Central Asia and Pakistan. It is located at a junction with other notable mountains, namely the Tian Shan, Karakoram, Kunlun, Hindu Kush and the Himalaya mountain ranges. They are among the world's highest mountains. Much of the Pamir Mountains lie in the Gorno-Badakhshan Province of Tajikistan. To the south, they border the Hindu Kush mountains along Afghanistan's Wakhan Corridor in Badakhshan Province, Chitral District, Chitral and Gilgit-Baltistan regions of Pakistan. To the north, they join the Tian Shan mountains along the Alay Valley of Kyrgyzstan. To the east, they extend to the range that includes China's Kongur Tagh, in the "Eastern Pamirs", separated by the Yarkand River, Yarkand valley from the Kunlun Mountains. Name and etymology Since Victorian times, they have been known as the "Roof of the World", presumably a translation from Persian language, Persian.

Journal Of Conchology
The ''Journal of Conchology'' is a peer-reviewed scientific journal published by The Conchological Society of Great Britain and Ireland, covering research in conchology and malacology. It claims to be the world's oldest continuing publication on the subject. The journal publishes original research and short communications on molluscs, with emphasis on conservation, biogeography and taxonomy. The contents include descriptions of new species from anywhere in the world, and reports concerning the ecology Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ..., distribution, and status of molluscs, both living and fossil.

Animalbase
AnimalBase is a project brought to life in 2004 and is maintained by the University of Göttingen, Germany. The goal of the AnimalBase project is to digitize early zoological literature, provide copyright-free open access to zoological works, and provide manually verified lists of names of zoological genera and species as a free resource for the public. AnimalBase contributed to opening up the classical taxonomic literature, which is considered as useful because access to early literature (especially for the late 18th century) can be difficult for researchers who need the old sources for their taxonomic research. AnimalBase data are public domain. The public use of AnimalBase data is not restricted or conditioned.AnimalBase Project Group, 2005-2010. AnimalBase. Early zoological literature online.

Karakorum
Karakorum (Khalkha Mongolian: Хархорум, ''Kharkhorum''; Mongolian Script:, ''Qaraqorum''; ) was the capital of the Mongol Empire between 1235 and 1260 and of the Northern Yuan dynasty in the 14–15th centuries. Its ruins lie in the northwestern corner of the Övörkhangai Province of modern-day Mongolia, near today's town of Kharkhorin and adjacent to the Erdene Zuu Monastery, the probably earliest surviving Buddhist monastery in Mongolia. They are part of the upper part of the World Heritage Site Orkhon Valley. History Foundation of empires The Orkhon valley was a center of the Xiongnu, Göktürk, and Uyghur empires. To the Göktürks, the nearby Khangai Mountains had been the location of the Ötüken (the locus of power), and the Uyghur capital Karabalgasun was located close to where later Karakorum would be erected (downstream the Orkhon River 27 km north–west from Karakorum). This area is probably also one of the oldest farming areas in Mongolia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mongolia
Mongolia; Mongolian script: , , ; lit. "Mongol Nation" or "State of Mongolia" () is a landlocked country in East Asia, bordered by Russia to the north and China to the south. It covers an area of , with a population of just 3.3 million, making it the world's most sparsely populated sovereign nation. Mongolia is the world's largest landlocked country that does not border a closed sea, and much of its area is covered by grassy steppe, with mountains to the north and west and the Gobi Desert to the south. Ulaanbaatar, the capital and largest city, is home to roughly half of the country's population. The territory of modern-day Mongolia has been ruled by various nomadic empires, including the Xiongnu, the Xianbei, the Rouran, the First Turkic Khaganate, and others. In 1206, Genghis Khan founded the Mongol Empire, which became the largest contiguous land empire in history. His grandson Kublai Khan conquered China proper and established the Yuan dynasty.
