Seasonal Flooding
A season is a division of the year based on changes in weather, ecology, and the number of daylight hours in a given region. On Earth, seasons are the result of the axial parallelism of Earth's tilted orbit around the Sun. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant. Various cultures define the number and nature of seasons based on regional variations, and as such there are a number of both modern and historical cultures whose number of seasons varies. The Northern Hemisphere experiences most direct sunlight during May, June, and July, as the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to ...

Agricultural Expansion
Agricultural expansion describes the growth of agricultural land (arable land, pastures, etc.) especially in the 20th and 21st centuries. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy requirements due to continuing population growth (both which in turn have been attributed to agricultural expansion itself), with an estimated expectation of 10 to 11 billion humans on Earth by end of this century. It is foreseen that most of the world's non-agrarian ecosystems (terrestrial and aquatic) will be affected adversely, from habitat loss, land degradation, overexploitation, and other problems. The intensified food (and biofuel) production will in particular affect the tropical regions. Most modern agriculture relies on intensive methods. Further expansion of the predominant farming types that rest on a small number of highly productive crops has led to a significant loss of biodiversity on a global scale already. More ...

Illegal Logging
Illegal logging is the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits. Illegal logging is a driving force for a number of environmental issues such as deforestation, soil erosion and biodiversity loss which can drive larger scale environmental crisis such as climate change and other forms of environmental degradation. Illegality may also occur during transport, such as illegal processing and export (through fraudulent declaration to customs); the avoidance of taxes and other charges, and fraudulent certification. These acts are often referred to as "wood laundering". Illegal logging is driven by a number of economic forces, such as demand for raw materials, land grabbing and demand for pasture for ...

Attalea Speciosa
''Attalea speciosa'', the babassu, babassu palm, ''babaçu, or cusi'', is a palm native to the Amazon Rainforest region in South America. The babassu palm is the predominant species in the Maranhão Babaçu forests of Maranhão and Piauí states. This plant has commercial value because its seeds produce an edible oil called babassu oil, which is also used in cleaners and skin-care products. The fruit is used to produce products such as medicines, beauty aids, and beverages. Traditional communities of the Maranhão region also produce a flour from the fruit, and this is commercialized as a nutritional supplement. The leaves are also used to provide thatch for houses and can be woven into mats for constructing house walls. The stems are used for timbers. The babassu palm is considered a weed in pasture areas of Cerrado vegetation in Brazil. Taxonomy In his 1995 ''The Palms of the Amazon'', Andrew Henderson recognised ''A. speciosa'' and '' A. spectabilis'' as valid spe ...

Swietenia Macrophylla
''Swietenia macrophylla'', commonly known as mahogany, Honduran mahogany, Honduras mahogany, or big-leaf mahogany is a species of plant in the Meliaceae family. It is one of three species that yields genuine mahogany timber (Swietenia), the others being ''Swietenia mahagoni'' and ''Swietenia humilis''. It is native to South America, Mexico and Central America, but naturalized in the Philippines, Singapore, Malaysia and Hawaii, and cultivated in plantations and wind-breaks elsewhere. Description Wood Mahogany wood is strong and is usually a source for furniture, musical instruments, ships, doors, coffins, decors. Leaves Mahogany is characterised by its large leaves (up to 45 cm long). The leaflets are even in number and are connected by a central midrib. Fruits The fruits are called "sky fruits" because of its upwards growth towards the sky. The fruits of mahogany can be measure to 40 cm in length, in a light grey to brown capsule. Each fruit capsule could contain 71 wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bactris Gasipaes
''Bactris gasipaes'' is a species of palm native to the tropical forests of Central and South America. It is well spread in these regions, where it is often cultivated by smallholders in agroforestry systems or more rarely, in monoculture. Common names include peach palm in English, among others used in South American countries. It is a long-lived perennial plant that is productive for 50 to 75 years on average. Its population has an important genetic diversity, leading to numerous fruits, colors, and qualities. The fruits are edible and nutritious but need to be cooked for 30 minutes to five hours. They also benefit many animals in the wild. Peach-palms are also cultivated for the heart of palm, and the trunk can make valuable timber. Description ''Bactris gasipaes'', like most sea-island palms, grows erect, with a single slender stem or, more often, several stems that are up to eight inches (20 cm) thick, in a cluster; generally armed with stiff, black spines in circular ...

Bactris Major
''Bactris major'' is a small to medium-sized (1–10 m tall) spiny palm which ranges from Mexico, through Central America into northern South America and Trinidad. The species is divided into three or four varieties, although the boundaries between varieties is not always clearly defined. The fruits are eaten or used to flavour drinks. Spanish names for the palm species include marayaú. Varieties Rafaël Govaerts recognised three varieties: * ''Bactris major'' var. ''major'' * ''Bactris major'' var. ''infesta'' (Mart.) Drude * ''Bactris major'' var. ''socialis'' (Mart.) Drude Andrew Henderson and co-authors recognised a fourth variety, ''Bactris major'' var. ''megalocarpa'' (Trail ex Thurn) A.J.Hend., but Govaerts considered this to be a synonym of ''Bactris major'' var. ''major''. References major Major (commandant in certain jurisdictions) is a military rank of commissioned officer status, with corresponding ranks existing in many military forces throughou ...

Herbalism
Herbal medicine (also herbalism) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from '' Artemisia annua'', a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of plants used in 21st century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine commonly includes fungal and bee products, as well as minerals, shells and certain animal parts. Herbal medicine is also called phytomedicine or phytotherapy. Paraherbalism describes alternative and pseudoscientific practices of using unrefined plant or animal extracts as unproven medicines or health-promoting agents. Paraherbalism relies on the belief that preserving various ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiber
Fiber or fibre (from la, fibra, links=no) is a natural or artificial substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. Synthetic fibers can often be produced very cheaply and in large amounts compared to natural fibers, but for clothing natural fibers can give some benefits, such as comfort, over their synthetic counterparts. Natural fibers Natural fibers develop or occur in the fiber shape, and include those produced by plants, animals, and geological processes. They can be classified according to their origin: *Vegetable fibers are generally based on arrangements of cellulose, often with lignin: examples include cotton, hemp, jute, flax, abaca, piña, ramie, sisal, bagasse, and banana. Plant fibers are employed in the manufacture of paper and textile (cloth), and die ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resin
In polymer chemistry and materials science, resin is a solid or highly viscous substance of plant or synthetic origin that is typically convertible into polymers. Resins are usually mixtures of organic compounds. This article focuses on naturally occurring resins. Plants secrete resins for their protective benefits in response to injury. The resin protects the plant from insects and pathogens. Resins confound a wide range of herbivores, insects, and pathogens, while the volatile phenolic compounds may attract benefactors such as parasitoids or predators of the herbivores that attack the plant. Composition Most plant resins are composed of terpenes. Specific components are alpha-pinene, beta-pinene, delta-3 carene, and sabinene, the monocyclic terpenes limonene and terpinolene, and smaller amounts of the tricyclic sesquiterpenes, longifolene, caryophyllene, and delta-cadinene. Some resins also contain a high proportion of resin acids. Rosins on the other hand are less ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beni Department
Beni (), sometimes El Beni, is a northeastern department of Bolivia, in the lowlands region of the country. It is the second-largest department in the country (after Santa Cruz), covering 213,564 square kilometers (82,458 sq mi), and it was created by supreme decree on November 18, 1842, during the administration of General José Ballivián. Its capital is Trinidad. Population With a population of 420,000 (2006 census), Beni is the second least-populated of the nine departments of Bolivia, after Pando. Although Beni is rich in natural resources, the poverty level of its inhabitants is high, mainly as a result of centuries of exploitation of native populations by European-descended elites. The main economic activities are agriculture, timber, and cattle. In addition, an underground economy linked to illegal narcotics activities flourished in the area during the last decades of the 20th century, with many cocaine laboratories hidden behind the façade of remote cattle ranches. ...
