Phumdis
Phumdi ( Meitei pronunciation: /pʰúm.dí/), also known as Phumthi ( Meitei pronunciation: /pʰúm.tʰí/) or simply Phum ( Meitei pronunciation: /pʰúm/), are a series of floating islands, exclusive to the Loktak Lake in Manipur state, in northeastern India. They cover a substantial part of the lake area and are heterogeneous masses of vegetation, soil and organic matter, in different stages of decay. The largest single mass of phumdi is in the southeastern part of the lake, covering an area of . This mass constitutes the world’s largest floating park, named Keibul Lamjao National Park. The park was formed to preserve the endangered Eld's deer subspecies, called sangai in the Meitei language, indigenous to this area. Phumdis are used by the local people for constructing their huts for fishing and other livelihood uses, and are inhabited by about 4000 people. ''Athapums'' are artificial circular phumdis, built by the villagers as enclosures for fish farming; aquacultur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eld's Deer
Eld's deer (''Rucervus eldii'' or ''Panolia eldii''Pitraa, Fickela, Meijaard, Groves (2004). ''Evolution and phylogeny of old world deer.'' Molecular Phylogenetics and Evolution 33: 880–895.), also known as the thamin or brow-antlered deer, is an Endangered species of deer endemic to South and Southeast Asia. It inhabits wetlands and marshlands. It is active during the day and mates from October to the end of December. Three subspecies are recognised. All three are threatened by hunting and deforestation. Taxonomy The species was first described by John McClelland in 1840 based on specimens obtained in Manipur, India. It was described more detailed by Percy Eld in 1841; it was suggested to call the deer ''Cervus Eldii''. McClelland coined the scientific name ''Cervus (Rusa) frontals'' in 1843. In 1850, John Edward Gray proposed the name ''Panolia eldii'' for the deer. It has recently been proposed that it should be moved back to the genus ''Panolia'' on the basis of recent ge ...

States And Territories Of India
India is a federalism, federal union comprising 28 federated state, states and 8 union territory, union territories, for a total of 36 subnational entities. The states and union territories are further subdivided into 800 List of districts in India, districts and smaller administrative divisions of India, administrative divisions by the respective subnational government. The states of India are self-governing administrative divisions, each having a State governments of India, state government. The governing powers of the states are shared between the state government and the Government of India, union government. On the other hand, the union territories are directly governed by the union government. History 1876–1919 The British Raj was a very complex political entity consisting of various imperial divisions and states and territories of varying autonomy.

Humus
In classical soil science, humus is the dark organic matter in soil that is formed by the decomposition of plant and animal matter. It is a kind of soil organic matter. It is rich in nutrients and retains moisture in the soil. Humus is the Latin word for "earth" or "ground". In agriculture, "humus" sometimes also is used to describe mature or natural compost extracted from a woodland or other spontaneous source for use as a soil conditioner. It is also used to describe a topsoil horizon that contains organic matter (''humus type'', ''humus form'', or ''humus profile''). Humus has many nutrients that improve the health of soil, nitrogen being the most important. The ratio of carbon to nitrogen ( C:N) of humus commonly ranges between 8:1 and 15:1 with the median being about 12:1. It also significantly improves (decreases) the bulk density of soil. Humus is amorphous and lacks the cellular structure characteristic of organisms. The solid residue of sewage sludge treatment, w ...

Capillipedium
''Capillipedium'' (common name scented-tops) is a genus of plants in the grass family. They are native to Africa, Asia, Australia, and certain islands in the Western Pacific. '' Capillipedium mistryi'' is an exception in the genus from India in which solid instead of translucent pedicels are seen and spikelets are multispiculated, racemes comprising up to 25 spikelets.

Cyperaceae
The Cyperaceae () are a family of graminoid (grass-like), monocotyledonous flowering plants known as wikt:sedge, sedges. The family (biology), family is large; botanists have species description, described some 5,500 known species in about 90 genus, generathe largest being the "true wikt:sedge, sedges" (genus ''Carex''), with over 2,000 species. Distribution Cyperaceae species are widely distributed with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges grow in almost all environments, many thrive in wetlands or in poor soils. Community (ecology), Ecological communities dominated by sedges are known as s or as sedge meadows. Classification Some species superficially resemble the closely related Juncaceae , rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example be ...

Poaceae
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials ( bamboo, thatch, and straw); oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biomass (ecology)
Biomass is the mass of living biological organisms in a given area or ecosystem at a given time. Biomass can refer to ''species biomass'', which is the mass of one or more species, or to ''community biomass'', which is the mass of all species in the community. It can include microorganisms, plants or animals. The mass can be expressed as the average mass per unit area, or as the total mass in the community. How biomass is measured depends on why it is being measured. Sometimes, the biomass is regarded as the natural mass of organisms ''in situ'', just as they are. For example, in a salmon fishery, the salmon biomass might be regarded as the total wet weight the salmon would have if they were taken out of the water. In other contexts, biomass can be measured in terms of the dried organic mass, so perhaps only 30% of the actual weight might count, the rest being water. For other purposes, only biological tissues count, and teeth, bones and shells are excluded. In some application ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nutrient
A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons. Some nutrients can be metabolically converted into smaller molecules in the process of releasing energy such as for carbohydrates, lipids, proteins and fermentation products ( ethanol or vinegar) leading to end-products of water and carbon dioxide. All organisms require water. Essential nutrients for animals are the energy sources, some of the amino acids that are combined to create proteins, a subset of fatty acids, vitamins and certain minerals. Plants require more diverse minerals absorbed through roots, plus carbon dioxide and oxygen absorbed through leaves. Fungi live on dead or living organic matter and meet nutrient needs from th ...
