Plateau Pika
The plateau pika (''Ochotona curzoniae''), also known as the black-lipped pika, is a species of mammal in the pika family, Ochotonidae. It is a small diurnal and non-hibernating mammal weighing about 140 g when fully grown. The animals are reddish tan on the top-side with more of a whitish yellow on their under-belly. They prefer to live in elevations of 3,100 to 5,000 m, mostly in the Tibetan Plateau, which is where the common name originates from. The species is found in China, Pakistan, India, and Nepal in high alpine deserts, steppe and meadows, as well as tropical and subtropical montane forests. Role in the ecosystem Plateau pikas are considered to be a keystone species as they play a role in recycling nutrients in soil, providing food to predators such as; foxes, weasels, falcons, Asia pole cat, upland buzzard, and owls. They also provide microhabitats by increasing plant richness and their burrows provides nests for small birds and reptiles. According to the ...

Brian Houghton Hodgson
Brian Houghton Hodgson (1 February 1800 or more likely 1801 – 23 May 1894) was a pioneer naturalist and ethnologist working in India and Nepal where he was a British Resident. He described numerous species of birds and mammals from the Himalayas, and several birds were named after him by others such as Edward Blyth. He was a scholar of Newar Buddhism and wrote extensively on a range of topics relating to linguistics and religion. He was an opponent of the British proposal to introduce English as the official medium of instruction in Indian schools. Early life Hodgson was the second of seven children of Brian Hodgson (1766–1858) and his wife Catherine (1776–1851), and was born at Lower Beech, Prestbury, Cheshire. His father lost money in a bad bank investment and had to sell their home at Lower Beech. A great-aunt married to Beilby Porteus, the Bishop of London, helped them but the financial difficulties were great. Hodgson's father worked as a warden of the Martello tow ...

Hoh Xil
Hoh Xil or Kekexili, ( Mongolian for "Blue Ridge", also Aqênganggyai for "Lord of Ten Thousand Mountains"), is an isolated region in the northeastern part of Qinghai-Tibet Plateau. On July 7, 2017, the Hoh Xil in Qinghai was listed among the World Heritage Sites as "the largest and highest plateau in the world". Geography The region covers 83,000 square kilometres at an average elevation of 4,800 metres above sea level, stretches in the east-west direction between the Tanggula and Kunlun mountain chains in the border areas of southwest China's Tibet Autonomous Region, northwest China's Qinghai Province and China's Xinjiang Uyghur Autonomous Region. The southeastern part of the Hoh Xil, drained by the Chumar River (), is one of the major headwater sources of the Yangtze River. The rest of the region is endorheic, with drainage to numerous isolated lakes; this area is sometimes described by hydrologists as the "Hoh Xil lake district". 45,000 square kilometres of the Hoh Xil re ...

Mammals Of Tibet
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla (cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saurops ...

Mammals Of India
This list of mammals of India comprises all the mammal species alive in India today. Some of them are common to the point of being considered vermin while others are exceedingly rare. Many species are known from just a few zoological specimens in museums collected in the 19th and 20th centuries. Many of the carnivores and larger mammals are restricted in their distribution to forests in protected areas, while others live within cities in the close proximity of humans. They range in size from the Eurasian pygmy shrew (''Sorex minutus'') to the Asian elephant (''Elephas maximus''). They include nocturnal small mammals endemic to India such as the Malabar large-spotted civet (''Viverra civettina''). While the status of many of these species is unknown, some are definitely extinct. Populations of many carnivores are threatened. The tiger (''Panthera tigris''), dhole (''Cuon alpinus''), and Malabar large-spotted civet (''Viverra civettina'') are some of the most endangered carni ...

Mammals Of Nepal
Wildlife diversity is a notable feature of Nepal. Because of the variance in climate, from tropical to arctic, Nepal has a large variety of plants and animals. Wildlife tourism is also a major source of tourism in the country. There are some animal species which are unique to Nepal, such as the spiny babbler. Nepal is also host to many rhododendron species. The wildlife of Nepal includes its flora and fauna. Nepal has established numerous national parks and reserves in order to protect its diverse fauna. Nepal is a biodiversity hot spot with ecoregions broadly comprising the mountainous ecoregion, the savanna and grasslands ecoregion of the terai (foothills), and the Rara Lake ecoregion, which has many endemic species. Legal protection Nepal has established numerous national parks and reserves in order to protect its diverse fauna ever since 1973, with the passing of the National Parks and Wildlife Conservation Act 2029 BS. There are four different "classes" of protection, rangi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pikas
A pika ( or ; archaically spelled pica) is a small, mountain-dwelling mammal found in Asia and North America. With short limbs, very round body, an even coat of fur, and no external tail, they resemble their close relative, the rabbit, but with short, rounded ears. The large-eared pika of the Himalayas and nearby mountains is found at heights of more than , among the highest of any mammal. Pikas prefer rocky slopes and graze on a range of plants, mostly grasses, flowers and young stems. In the autumn they pull hay, soft twigs and other stores of food into their burrows to eat during the long, cold winter. The pika is also known as the whistling hare because of its high-pitched alarm call when diving into its burrow. The name ‘pika’ appears to be derived from the Tungus ''piika'', and the scientific name ''Ochotona'' is from the Mongolian word ''ogutun-a, оготно'', which means pika. It is used for any member of the Ochotonidae, a family within the order of lagomo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loss Of Biodiversity
Biodiversity loss includes the worldwide extinction of different species, as well as the local reduction or loss of species in a certain habitat, resulting in a loss of biological diversity. The latter phenomenon can be temporary or permanent, depending on whether the environmental degradation that leads to the loss is reversible through ecological restoration/ecological resilience or effectively permanent (e.g. through land loss). The current global extinction (frequently called the sixth mass extinction or Anthropocene extinction), has resulted in a biodiversity crisis being driven by human activities which push beyond the planetary boundaries and so far has proven irreversible. Even though permanent global species loss is a more dramatic and tragic phenomenon than regional changes in species composition, even minor changes from a healthy stable state can have dramatic influence on the food web and the food chain insofar as reductions in only one species can adversely affect ...

Plateau Pika Xining China 2016
In geology and physical geography, a plateau (; ; ), also called a high plain or a tableland, is an area of a highland consisting of flat terrain that is raised sharply above the surrounding area on at least one side. Often one or more sides have deep hills or escarpments. Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, and erosion by water and glaciers. Plateaus are classified according to their surrounding environment as intermontane, piedmont, or continental. A few plateaus may have a small flat top while others have wide ones. Formation Plateaus can be formed by a number of processes, including upwelling of volcanic magma, extrusion of lava, Plate tectonics movements and erosion by water and glaciers. Volcanic Volcanic plateaus are produced by volcanic activity. The Columbia Plateau in the north-western United States is an example. They may be formed by upwelling of volcanic magma or extrusion of lava. The un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soil Health
Soil health is a state of a soil meeting its range of ecosystem functions as appropriate to its environment. In more colloquial terms, the health of soil arises from favorable interactions of all soil components (living and non-living) that belong together, as in microbiota, plants and animals. It is possible that a soil can be healthy in terms of eco-system functioning but not necessarily serve crop production or human nutrition directly, hence the scientific debate on terms and measurements. Soil health testing is pursued as an assessment of this status but tends to be confined largely to agronomic objectives, for obvious reasons. Soil health depends on soil biodiversity (with a robust soil biota), and it can be improved via soil management, especially by care to keep protective living covers on the soil and by natural (carbon-containing) soil amendments. Inorganic fertilizers do not necessarily damage soil health if 1) used at appropriate and not excessive rates and 2) if they ...

Brown Bear
The brown bear (''Ursus arctos'') is a large bear species found across Eurasia and North America. In North America, the populations of brown bears are called grizzly bears, while the subspecies that inhabits the Kodiak Islands of Alaska is known as the Kodiak bear. It is one of the largest living terrestrial members of the order Carnivora, rivaled in size only by its closest relative, the polar bear (''Ursus maritimus''), which is much less variable in size and slightly bigger on average. The brown bear's range includes parts of Russia, Central Asia, the Himalayas, China, Canada, the United States, Hokkaido, Scandinavia, Finland, the Balkans, the Picos de Europa and the Carpathian region (especially Romania), Iran, Anatolia, and the Caucasus. The brown bear is recognized as a national and state animal in several European countries. While the brown bear's range has shrunk, and it has faced local extinctions across its wide range, it remains listed as a least concern ...
