Diptychus is a genus of cyprinid freshwater fish, consisting of two species found in Himalaya and the Tibetan Plateau of China, India, Nepal and Pakistan, ranging west to the Tien Shan Mountains and Central Asia. [1] [2] The type species is the scaly osman, Diptychus maculatus. The name is derived from the Greek word di, meaning "two", and the Greek word ptyx, meaning "fold". Diptychus is up to 70 cm (2.3 ft) in total length. [1]
Diptychus is a part of the schizothoracines (snowtrout and allies), which also includes the genera Aspiorhynchus , Chuanchia , Gymnodiptychus , Gymnocypris , Oxygymnocypris , Platypharodon , Ptychobarbus , Schizopyge , Schizopygopsis and Schizothorax . [3]
There are two recognized species in this genus: [1]
The Tibetan mastiff is a large Tibetan dog breed. Its double coat is long, subject to climate, and found in a wide variety of colors, including solid black, black and tan, various shades of red and bluish-gray, often with white and blue markings.
Coelodonta is an extinct genus of rhinoceros that lived in Eurasia between 3.7 million years to 10,000 years before the present, in the Pliocene and the Pleistocene epochs. It is best known from the type species, the woolly rhinoceros, which ranged throughout northern Eurasia during the Pleistocene.
Omeisaurus is a genus of sauropod dinosaur from the Middle Jurassic Period of what is now China. Its name comes from Mount Emei, where it was discovered in the lower Shaximiao Formation of Sichuan Province.
Rheum is a genus of about 60 herbaceous perennial plants in the family Polygonaceae. Species are native to eastern Europe, southern and eastern temperate Asia, with a few reaching into northern tropical Asia. Rheum is cultivated in Europe and North America. The genus includes the vegetable rhubarb. The species have large somewhat triangular shaped leaves with long, fleshy petioles. The flowers are small, greenish-white to rose-red, and grouped in large compound leafy inflorescences. A number of cultivars of rhubarb have been domesticated both as medicinal plants and for human consumption. While the leaves are slightly toxic, the stalks are used in pies and other foods for their tart flavor.
Thermophis baileyi, also known as Bailey's snake or the hot-spring snake, is a rare species of colubrid snake endemic to Tibet.
The Himalayan wolf is a canine of debated taxonomy. It is distinguished by its genetic markers, with mitochondrial DNA indicating that it is genetically basal to the Holarctic grey wolf, genetically the same wolf as the Tibetan wolf, and has an association with the African golden wolf. No striking morphological differences are seen between the wolves from the Himalayas and those from Tibet. The Himalayan wolf lineage can be found living in the Himalayas, the Tibetan Plateau, and the Central Asian highlands predominantly above 4,000 m in elevation because it has adapted to a low-oxygen environment, compared with other wolves that are found only at lower elevations.
Schizothorax is a genus of cyprinid fish found in southern and western China, through northern South Asia (Himalaya) and Central Asia, to Iran, with a single species, S. prophylax, in Turkey. They are primarily found in highland rivers, streams and lakes, although a few species occur in lower-lying locations, like Lake Balkhash and lakes of the Sistan Basin. Their scientific name means "cloven-breast", from Ancient Greek schízeïn (σχίζειν) "to cleave" and thórax (θώραξ) "breast-plate". The western species are typically referred to as marinkas from their Russian name marinka (маринка), while the eastern species are usually called snowtrout. Although they do resemble trouts in habitus this is merely due to convergent evolution and they are by no means closely related apart from both being Teleostei: Cyprinids are in the teleost superorder Ostariophysi, while trouts are in the superorder Protacanthopterygii. Their ancestors must thus have diverged as early as the Triassic, more than 200 million years ago.
Sinocyclocheilus is a genus of freshwater fish in the family Cyprinidae endemic to China, where only found in Guangxi, Guizhou and Yunnan. Almost all of its species live in or around caves and most of these have adaptions typical of cavefish such as a lack of scales, lack of pigmentation and reduced eyes. Several species have an unusual hunchbacked appearance and some of the cave-dwellers have a "horn" on the back, the function of which is unclear. In contrast, the Sinocyclocheilus species that live aboveground, as well as a few found underground, show no clear cavefish adaptions. They are relatively small fish reaching up to 23 cm (9.1 in) in length. The individual species have small ranges and populations, leading to the status of most of the evaluated species as threatened. Many species populations in the genus have yet to be evaluated by the IUCN.
Acheilognathus is a genus of cyprinid fish native to Asia. The name is derived from the Greek a, meaning "without", the Greek cheilos, meaning "lip", and the Greek gnathos, meaning "jaw".
Perenniporia is a cosmopolitan genus of bracket-forming or crust-like polypores in the family Polyporaceae. They are dimitic or trimitic with smooth, thick-walled basidiospores and cause a white rot in affected wood.
Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera, but as Wikipedia follows Fishbase for fish species these have been treated as subgenera in Wikipedia, although Kottelat and the Catalog of Fishes treat them as genera. FishBase, however, includes these in Triplophysa without specifying subgenera and treats the names given by Kottelat as synonyms.
The plateau pika, also known as the black-lipped pika, is a species of mammal in the pika family, Ochotonidae.
Schizopygopsis is a genus of cyprinid fish. Most species are endemic to river basins in the Himalayas and Qinghai–Tibet Plateau of China, but S. stoliczkai extends into the highlands of Afghanistan, Iran, northern India, Kyrgyzstan, Pakistan and Tajikistan.
The false osman is an Asian cyprinid freshwater fish living in the highlands of Afghanistan, southwestern China, Iran, northern India, Kyrgyzstan, Pakistan and Tajikistan. Young individuals and small adults live in shallow streams and pools, while large adults inhabit the main river and lakes. It grows to 34 cm (13 in) in total length.
The scaly osman is a species of cyprinid freshwater fish. It is native to Himalaya and the Tibetan Plateau of China, India, Nepal and Pakistan, ranging west to the Tien Shan Mountains and Central Asia. It is up to 70 cm (2.3 ft) in total length.
Chuanchia labiosa is a species of cyprinid fish that is only found in the upper reaches of the Yellow River basin in the Qinghai–Tibet Plateau of China, where it mostly inhabits slow-flowing cold waters at altitudes above 3,000 m (9,800 ft). It is the only member of its genus, but is related to other schizothoracines like Aspiorhynchus, Diptychus, Gymnodiptychus, Gymnocypris, Oxygymnocypris, Platypharodon, Ptychobarbus, Schizopyge, Schizopygopsis and Schizothorax.
Platypharodon extremus is a species of cyprinid fish endemic to the upper Yellow River basin in the Qinghai–Tibet Plateau of China. It is the only member of its genus, but is related to other schizothoracines like Aspiorhynchus, Chuanchia, Gymnocypris, Oxygymnocypris, Ptychobarbus, Schizopyge, Schizopygopsis and Schizothorax.
Ptychobarbus is a genus of cyprinid fish that is found in rivers, streams and lakes in the Himalayas and Tibetan Plateau of China, India, Nepal and Pakistan, extending into the highlands of Afghanistan. They reach up to 2.2 kg (5 lb) in weight and about 65 cm (2.1 ft) in total length. They mostly feed on benthic invertebrates, but will also take planktonic organisms, aquatic plants and algae.
The Tizinafu River, also spelled Tiznef River or Tiznaf River or Tiznap River or Tizinapu River, formerly known as the Tingzaabu River (听杂阿布河), is a river in the Xinjiang Uygur Autonomous Region of the People's Republic of China, located in southeast Kashi, originates in the northern slope of the Kunlun Mountains.
