Robert Wight
Robert Wight Doctor of Medicine, MD Fellow of the Royal Society, FRS Linnean Society of London, FLS (6 July 1796 – 26 May 1872) was a Scottish surgeon in the East India Company, whose professional career was spent entirely in southern India, where his greatest achievements were in botany – as an economic botanist and leading taxonomist in south India. He contributed to the introduction of Gossypium barbadense, American cotton. As a taxonomist he described 110 new genera and 1267 new species of flowering plants. He employed Indian botanical artists to illustrate many plants collected by himself and Indian collectors he trained. Some of these illustrations were published by William Jackson Hooker, William Hooker in Britain, but from 1838 he published a series of illustrated works in Madras including the uncoloured, six-volume ''Icones Plantarum Indiae Orientalis'' (1838–53) and two hand-coloured, two-volume works, the ''Illustrations of Indian Botany'' (1838–50) and ''Spic ...

Traditional Medicine
Traditional medicine (also known as indigenous medicine or folk medicine) comprises medical aspects of traditional knowledge that developed over generations within the folk beliefs of various societies, including indigenous peoples, before the era of modern medicine. The World Health Organization (WHO) defines traditional medicine as "the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness". Traditional medicine is often contrasted with scientific medicine. In some Asian and African countries, up to 80% of the population relies on traditional medicine for their primary health care needs. When adopted outside its traditional culture, traditional medicine is often considered a form of alternative medicine. Practices known as traditional medicines ...

Orchids Of India
Orchids are plants that belong to the family Orchidaceae (), a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Along with the Asteraceae, they are one of the two largest families of flowering plants. The Orchidaceae have about 28,000 currently accepted species, distributed in about 763 genera. (See ''External links'' below). The determination of which family is larger is still under debate, because verified data on the members of such enormous families are continually in flux. Regardless, the number of orchid species is nearly equal to the number of bony fishes, more than twice the number of bird species, and about four times the number of mammal species. The family encompasses about 6–11% of all species of seed plants. The largest genera are ''Bulbophyllum'' (2,000 species), ''Epidendrum'' (1,500 species), ''Dendrobium'' (1,400 species) and ''Pleurothallis'' (1,000 species). It also includes ''Vanilla'' (the genus of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epiphytic Orchids
An epiphyte is an organism that grows on the surface of a plant and derives its moisture and nutrients from the air, rain, water (in marine environments) or from debris accumulating around it. The plants on which epiphytes grow are called phorophytes. Epiphytes take part in nutrient cycles and add to both the diversity and biomass of the ecosystem in which they occur, like any other organism. They are an important source of food for many species. Typically, the older parts of a plant will have more epiphytes growing on them. Epiphytes differ from parasites in that they grow on other plants for physical support and do not necessarily affect the host negatively. An organism that grows on another organism that is not a plant may be called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanilla
Vanilla is a spice derived from orchids of the genus ''Vanilla (genus), Vanilla'', primarily obtained from pods of the Mexican species, flat-leaved vanilla (''Vanilla planifolia, V. planifolia''). Pollination is required to make the plants produce the fruit from which the vanilla spice is obtained. In 1837, Belgian botanist Charles François Antoine Morren discovered this fact and pioneered a method of artificially pollinating the plant. The method proved financially unworkable and was not deployed commercially. In 1841, Edmond Albius, a 12-year-old enslaved child who lived on the French island of Réunion in the Indian Ocean, discovered that the plant could be hand-pollination, hand-pollinated. Hand-pollination allowed global cultivation of the plant. Noted French botanist and plant collector Jean Michel Claude Richard falsely claimed to have discovered the technique three or four years earlier. By the end of the 20th century, Albius was considered the true discoverer ... [...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, introdu ...

Overexploitation
Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns. Continued overexploitation can lead to the destruction of the resource, as it will be unable to replenish. The term applies to natural resources such as water aquifers, grazing pastures and forests, wild medicinal plants, fish stocks and other wildlife. In ecology, overexploitation describes one of the five main activities threatening global biodiversity. Ecologists use the term to describe populations that are harvested at an unsustainable rate, given their natural rates of mortality and capacities for reproduction. This can result in extinction at the population level and even extinction of whole species. In conservation biology, the term is usually used in the context of human economic activity that involves the taking of biological resources, or organisms, in larger numbers than their populations can withstand. The term is also used and defined some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fever
Fever, also referred to as pyrexia, is defined as having a body temperature, temperature above the human body temperature, normal range due to an increase in the body's temperature Human body temperature#Fever, set point. There is not a single agreed-upon upper limit for normal temperature with sources using values between in humans. The increase in set point triggers increased muscle tone, muscle contractions and causes a feeling of cold or chills. This results in greater heat production and efforts to conserve heat. When the set point temperature returns to normal, a person feels hot, becomes Flushing (physiology), flushed, and may begin to Perspiration, sweat. Rarely a fever may trigger a febrile seizure, with this being more common in young children. Fevers do not typically go higher than . A fever can be caused by many medical conditions ranging from non-serious to life-threatening. This includes viral infection, viral, bacterial infection, bacterial, and parasitic infect ...

Cattle
Cattle (''Bos taurus'') are large, domesticated, cloven-hooved, herbivores. They are a prominent modern member of the subfamily Bovinae and the most widespread species of the genus ''Bos''. Adult females are referred to as cows and adult males are referred to as bulls. Cattle are commonly raised as livestock for meat (beef or veal, see beef cattle), for milk (see dairy cattle), and for hides, which are used to make leather. They are used as riding animals and draft animals ( oxen or bullocks, which pull carts, plows and other implements). Another product of cattle is their dung, which can be used to create manure or fuel. In some regions, such as parts of India, cattle have significant religious significance. Cattle, mostly small breeds such as the Miniature Zebu, are also kept as pets. Different types of cattle are common to different geographic areas. Taurine cattle are found primarily in Europe and temperate areas of Asia, the Americas, and Australia. Zebus (also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Irulas
Irula, also known as Iruliga'','' are a Dravidian ethnic group inhabiting the Indian states of Tamil Nadu, Kerala and Karnataka. A scheduled tribe, their population in this region is estimated at around 200,000 people. People of Irula ethnicity are called ''Irular'', and speak Irula, which belongs to the Dravidian family. Etymology ''Irular'' means "dark people" in Tamil and Malayalam, from the root word ''irul'', meaning "darkness." Thurston speculated that it either referred to the darkness of the jungles which they inhabited or their dark skin complexion. Distribution The tribe numbers around 200,000 spread across three states: 189,621 in Tamil Nadu, 23,721 in Kerala and 10,259 in Karnataka. Those in Karnataka are named Iruligas. The Irulas are mainly concentrated in northern Tamil Nadu: in a wedge extending from Krishnagiri and Dharmapuri districts in the west to Ariyalur and Cuddalore districts in the south and Tiruvallur district in the north.

Anna Maria Walker
Anna Maria Walker (née Patton) (c. 1778–1852) and her husband Colonel George Warren Walker (1778–1843) were Scottish botanists in Ceylon (now Sri Lanka) who made extensive collections of plants between 1830 and 1838. Several species of ferns and orchids were named after them by Sir William Jackson Hooker with whom they corresponded. They also corresponded with and collaborated with other botanists in the region such as Robert Wight. Anna Maria was also an excellent botanical artist who illustrated many species of orchids.Noltie, H.J. (2013). The Botanical Collections of Colonel and Mrs Walker: Ceylon, 1830 – 1838. Royal Botanic Garden Edinburgh. Plant species named after them include '' Vanilla walkeriae'', '' Liparis walkeriae'' and '' Thrixspermum walkeri''.

Vanilla (genus)
''Vanilla'', the vanilla orchids, forms a flowering plant genus of about 110 species in the orchid family (Orchidaceae). The most widely known member is the flat-leaved vanilla ('' V. planifolia''), native to Mexico and Belize, from which commercial vanilla flavoring is derived. It is the only orchid widely used for industrial purposes in flavoring such products as foods, beverages and cosmetics, and is recognized as the most popular aroma and flavor. The key constituent imparting its flavour is the phenolic aldehyde, vanillin. This evergreen genus occurs worldwide in tropical and subtropical regions, from tropical America to tropical Asia, New Guinea and West Africa. Five species are known from the contiguous United States, all limited to southern Florida. The genus was established in 1754 by Plumier, based on J. Miller. The word vanilla, derived from the diminutive of the Spanish word vaina (vaina itself meaning sheath or pod), simply translates as little pod. Descriptio ...
