Psilorhynchus Microphthalmus
''Psilorhynchus microphthalmus'' is a freshwater ray-finned fish, a torrent minnow. It is restricted to the Chapki Stream in the Chindwin basin of Manipur, India. It is found in flowing water with a rock substrate. This species is threatened from the effects of the use of poisons and explosives for fishing and the sedimentation of its habitat caused by deforestation and slash and burn Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegeta ... agriculture. References microphthalmus Fish described in 1995 {{Psilorhynchus-stub ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Psilorhynchus
''Psilorhynchus'' is a genus of fish in the family ''Psilorhynchidae'' native to South Asia. This genus is the only member of its family (biology), family. The members of ''Psilorhynchus'' are small benthic fishes which occur in rivers and streams with fast to swift currents, hence they are often referred to a torrent minnows. They are distributed in southern Asia, in the Indo-Burma region and the Western Ghats. The genus is the sister group to the family Cyprinidae, and with that family the Psilorhynchidae makes up the superfamily Cyprinoidea, with all the other cypriniform families in the superfamily loach, Cobitoidea. Species There are currently 29 recognized species in this genus: * ''Psilorhynchus amplicephalus'' Muthukumarasamy Arunachalam, Arunachalam, Murugan Muralidharan, Muralidharan & Paramasivan Sivakumar, Sivakumar, 2007 * ''Psilorhynchus arunachalensis'' (Kongbrailatpan Nebeshwar-Sharma, Nebeshwar, Kenjum Bagra, Bagra & Debangshu Narayan Das, D.

Manipur
Manipur () ( mni, Kangleipak) is a state in Northeast India, with the city of Imphal as its capital. It is bounded by the Indian states of Nagaland to the north, Mizoram to the south and Assam to the west. It also borders two regions of Myanmar, Sagaing Region to the east and Chin State to the south. The state covers an area of . Manipur has been at the crossroads of Asian economic and cultural exchange for more than 2,500 years. It connects the Indian subcontinent and Central Asia to Southeast Asia, East Asia, Siberia, regions in the Arctic, Micronesia and Polynesia enabling migration of people, cultures and religions. During the days of the British Indian Empire, the Kingdom of Manipur was one of the princely states. Between 1917 and 1939, some people of Manipur pressed the princely rulers for democracy. By the late 1930s, the princely state of Manipur negotiated with the British administration its preference to continue to be part of the Indian Empire, rather than part of B ...

Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses (deforestation) and all forest gains (forest expansion) in a gi ...

Slash And Burn
Slash-and-burn agriculture is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. The method begins by cutting down the trees and woody plants in an area. The downed vegetation, or "slash", is then left to dry, usually right before the rainiest part of the year. Then, the biomass is burned, resulting in a nutrient-rich layer of ash which makes the soil fertile, as well as temporarily eliminating weed and pest species. After about three to five years, the plot's productivity decreases due to depletion of nutrients along with weed and pest invasion, causing the farmers to abandon the field and move to a new area. The time it takes for a swidden to recover depends on the location and can be as little as five years to more than twenty years, after which the plot can be slashed and burned again, repeating the cycle. In Bangladesh and India, the practice is known as jhum or jhoom. Slash-and-burn is a type of shif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
