Aquilaria Malaccensis
''Aquilaria malaccensis'' is a species of plant in the Thymelaeaceae family. It is found in Bangladesh, Bhutan, India, Indonesia, Laos, Malaysia, Myanmar, the Philippines, Singapore, and Thailand. It is threatened by habitat loss.Barden, Angela (2000) ''Heart of the Matter: Agarwood Use and Trade and CITES Implementation for Aquilaria malaccensis'' TRAFFIC International, Cambridge, ''The World List of Threatened Trees'' (Oldfield et al., 1998) listed Iran as one of the countries with a population of ''A. malaccensis'', but an exploratory 2002 CITES review confirmed that Iran has no record of the species. As a result Iran is no longer considered as habitat for or producer of agarwood. Economics ''Aquilaria malaccensis'' is the major sourceNg, L.T., Chang Y.S. and Kadir, A.A.

Munnar
Munnar () is a town and hill station in the Idukki district of the southwestern Indian state of Kerala. Munnar is situated at around above mean sea level, in the Western Ghats mountain range. Munnar is also called the "Kashmir of South India" and is a popular honeymoon destination. Etymology The name Munnar is believed to mean "three rivers", referring to its location at the confluence of the Mudhirapuzha, Nallathanni and Kundali rivers. History The region has been inhabited by hunter-gatherer tribals like the Malayarayan and Muthuvan for thousands of years. Tradition states that Colonel Arthur Wellesley, later the Duke of Wellington, was the first British person to pass through Munnar during Tippu Sultan's campaign in Travancore, but this is unsubstantiated. The first survey of the terrain was undertaken by Benjamin Swayne Ward in 1816–1817, who followed the Periyar into the Western Ghats and established a camp at the confluence of three rivers, from which the name ...

Habitat Loss
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 ...

Taxonomy Articles Created By Polbot
Taxonomy is the practice and science of categorization or classification (general theory), classification. A taxonomy (or taxonomical classification) is a scheme of classification, especially a hierarchical classification, in which things are organized into groups or types. Among other things, a taxonomy can be used to organize and index knowledge (stored as documents, articles, videos, etc.), such as in the form of a library classification system, or a Taxonomy for search engines, search engine taxonomy, so that users can more easily find the information they are searching for. Many taxonomies are hierarchy, hierarchies (and thus, have an intrinsic tree structure), but not all are. Originally, taxonomy referred only to the categorisation of organisms or a particular categorisation of organisms. In a wider, more general sense, it may refer to a categorisation of things or concepts, as well as to the principles underlying such a categorisation. Taxonomy organizes taxonomic uni ...

Aquilaria
''Aquilaria'' is a genus of fifteenNg, L.T., Chang Y.S. and Kadir, A.A. (1997) "A review on agar (gaharu) producing Aquilaria species" ''Journal of Tropical Forest Products'' 2(2): pp. 272-285 species of trees, called lign aloes or lign-aloes trees, in the family Thymelaeaceae, native to southeast Asia. They occur particularly in the rainforests of Indonesia, Thailand, Cambodia, Laos, Vietnam, Malaysia, Northeast India, Bangladesh, the Philippines, Borneo and New Guinea. The trees grow to 6–20 m tall. The leaves are alternate, 5–11 cm long and 2–4 cm broad, with a short acuminate apex and an entire margin. The flowers are yellowish-green, produced in an umbel; the fruit is a woody capsule 2.5–3 cm long. The genus is best known, together with ''Gyrinops'', as the principal producer of the resin-suffused agarwood used in aromatic incense production, especially ''Aquilaria malaccensis''.Barden, Angela (2000) ''Heart of the Matter: Agarwood Use and Trade and CI ...

Black Yeast
“Black yeasts”, sometimes also black fungi, dematiaceous fungi, microcolonial fungi or meristematic fungi is a diverse group of slow-growing microfungi which reproduce mostly asexually (fungi imperfecti). Only few genera reproduce by budding cells, while in others hyphal or meristematic (isodiametric) reproduction is preponderant. Black yeasts share some distinctive characteristics, in particular a dark colouration ( melanisation) of their cell wall. Morphological plasticity, incrustation of the cell wall with melanins and presence of other protective substances like carotenoids and mycosporines represent passive physiological adaptations which enable black fungi to be highly resistant against environmental stresses. The term " polyextremotolerance" has been introduced to describe this phenotype, a good example of which is the species ''Aureobasidium pullulans''. Presence of 1,8-dihydroxynaphthalene melanin in the cell wall confers to the microfungi their characteristic oli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ascomycetous
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the " ascus" (), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of the Ascomycota are asexual, meaning that they do not have a sexual cycle and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, brewers' and bakers' yeast, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (it contains all descendants of one common ancestor). Previously placed in the Deuteromycota along with asexual species from other fungal taxa, asexual (or anamorphic) ascom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agarwood
Agarwood, aloeswood, eaglewood or gharuwood is a fragrant dark resinous wood used in incense, perfume, and small carvings. This resinous wood is most commonly referred to as "Oud" or "Oudh". It is formed in the heartwood of aquilaria trees when the Acquilara Tree becomes infected with a type of mold (''Phialophora parasitica'') and secretes a resin to combat the mold. Prior to infection, the heartwood is odourless, relatively light and pale coloured; however, as the infection progresses, the tree produces a dark aromatic resin, called aloes (not to be confused with ''Aloe ferox'', the succulent commonly known as the bitter aloe) or agar (not to be confused with the edible, algae-derived agar) as well as ''gaharu'', ''jinko'', ''oud'', or ''oodh'' ''aguru'' (not to be confused with bukhoor), in response to the attack, which results in a very dense, dark, resin-embedded heartwood. The resin-embedded wood is valued in East and South Asian cultures for its distinctive fragrance, and ... [...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 ...
