Nepenthes Khasiana
''Nepenthes khasiana'' (; after the Khasi Hills, to which it is largely endemic) is an endangered tropical pitcher plant of the genus ''Nepenthes''. It is the only ''Nepenthes'' species native to India. It is thought to attract prey by means of blue fluorescence. The species has a very localised distribution and is rare in the wild. But with new advancement in agro-technology and tissue culture, it is now being cultivated in campus of Nagaland University, Nagaland. These Pitcher Plants which are endemic to Meghalaya can be seen widely as decorative plants outside many houses of Nagaland. Isolated populations are known to occur in the Jarain area of the Jaintia Hills, the Baghmara area of the Garo Hills, adjacent to the Khasi Hills region of Meghalaya, in the Upper Kharthong area, of Dima Hasao district Assam and in some parts of Nagaland.Sajem Betlu, A.L. 2016.

Joseph Dalton Hooker
Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For twenty years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified h ...

Nepenthes Aristolochioides
''Nepenthes aristolochioides'' is a tropical pitcher plant endemic to Sumatra, where it grows at elevations of 1800–2500 m above sea level. It has an extremely unusual pitcher morphology, having an almost vertical opening to its traps.McPherson, S.R. 2009. '' Pitcher Plants of the Old World''. 2 volumes. Redfern Natural History Productions, Poole. It is critically endangered by overcollection. The specific epithet ''aristolochioides'' is formed from the genus name ''Aristolochia'' and the Latin ending ''-oides'', meaning "resembling". It refers to the similarity that the pitchers of this species bear, in both shape and pigmentation, to the specialised flowers of ''Aristolochia''. Botanical history ''Nepenthes aristolochioides'' was first collected by Willem Meijer on August 5, 1956. The holotype, ''Meijer 6542'', was collected on that date from Mount Tujuh (Tudjuh) in Jambi at an elevation of 2000 m. It is deposited at the National Herbarium of the Netherlands ...

Coal Mining
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is called a 'pit', and the above-ground structures are a ' pit head'. In Australia, "colliery" generally refers to an underground coal mine. Coal mining has had many developments in recent years, from the early days of men tunneling, digging and manually extracting the coal on carts to large open-cut and longwall mines. Mining at this scale requires the use of draglines, trucks, conveyors, hydraulic jacks and shearers. The coal mining industry has a long history of significant negative environmental impacts on local ecosystems, health impacts on local communities and workers, and contributes heavily ...

Acid Mine Drainage
Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines. Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by large-scale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has been disturbed (e.g. construction sites, subdivisions, and transportation corridors) may create acid rock drainage. In many localities, the liquid that drains from coal stocks, coal handling facilities, coal washeries, and coal waste tips can be highly acidic, and in such cases it is treated as acid rock drainage. This liquid often contains highly toxic metals, such as copper or iron. These, combined with reduced pH, have a detrimental impact on the streams aquatic environments. The same type of chemical reactions and pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Destruction
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

Endangered
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Garo (tribe)
The Garo is a Tibeto-Burman ethnic tribal group from the Indian subcontinent, living mostly in the Indian states of Meghalaya, Assam, Tripura, and Nagaland, and in neighbouring areas of Bangladesh, including Madhupur, Mymensingh, Haluaghat, Dhobaura, Durgapur, Kolmakanda, Jamalpur, Sherpur, Jhinaigati, Nalitabari, Gazini Hills Madhyanagar, Bakshiganj and Sribardi. Historically, the name Garo was used for wide range of inhabitants in southern bank of Brahmaputra but now refers to those who call themselves A•chik Mande (literally "hill people," from ''A•chik'' "bite soil" + ''mande'' "people") or simply A•chik or Mande and the name "Garo" is now being used by outsiders as an exonym. They are the second-largest tribe in Meghalaya after the Khasi and comprise about a third of the local population. Religion Many of the Garo community follow Christianity, with some rural pockets practising traditional animist religion known as Songsarek. It is argued that the indi ...
