Tree
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loganiaceae
The Loganiaceae are a family of flowering plants classified in order Gentianales. The family includes up to 13 genera, distributed around the world's tropics. There are not any great morphological characteristics to distinguish these taxa from others in the order Gentianales. Many members of the Loganiaceae are extremely poisonous, causing death by convulsion. Poisonous properties are largely due to alkaloids such as those found in ''Strychnos''. Glycosides are also present as loganin in ''Strychnos''.Flowering Plants of the World by consultant editor Vernon H. Heywood, 1978, Oxford University Press, Walton Street, Oxford OX2 6DP, England, Earlier treatments of the family have included up to 29 genera. Phylogenetic studies have demonstrated that this broadly defined Loganiaceae was a polyphyletic assemblage, and numerous genera have been removed from Loganiaceae to other families (sometimes in other orders), e.g., Gentianaceae, Gelsemiaceae, Plocospermataceae, Tetrachondrac ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Côte D'Ivoire
Ivory Coast, also known as Côte d'Ivoire, officially the Republic of Côte d'Ivoire, is a country on the southern coast of West Africa. Its capital is Yamoussoukro, in the centre of the country, while its largest city and economic centre is the port city of Abidjan. It borders Guinea to the northwest, Liberia to the west, Mali to the northwest, Burkina Faso to the northeast, Ghana to the east, and the Gulf of Guinea (Atlantic Ocean) to the south. Its official language is French, and indigenous languages are also widely used, including Bété, Baoulé, Dioula, Dan, Anyin, and Cebaara Senufo. In total, there are around 78 different languages spoken in Ivory Coast. The country has a religiously diverse population, including numerous followers of Christianity, Islam, and indigenous faiths. Before its colonization by Europeans, Ivory Coast was home to several states, including Gyaaman, the Kong Empire, and Baoulé. The area became a protectorate of France in 1843 and ...

Eastern Guinean Forests
The Eastern Guinean forests are a tropical moist broadleaf forest ecoregion of West Africa. Geography The ecoregion includes the lowland forests extending from the Gulf of Guinea a few hundred kilometres inland, from western Côte d'Ivoire to the western shore of Lake Volta in Ghana. A few enclaves lie further east and inland in the Togo Mountains of Togo, eastern Ghana, and Benin. The Sassandra River of Cote d'Ivoire separates the Eastern Guinean forests from the Western Guinean forests which lie to the west. Inland and to the east, the Eastern Guinean forests transition to the Guinean forest-savanna mosaic.Burgess, Neil, Jennifer D’Amico Hales, Emma Underwood (2004). ''Terrestrial Ecoregions of Africa and Madagascar: A Conservation Assessment''. Island Press, Washington DC. Cities in the ecoregion include Abidjan and Yamoussoukro in Ivory Coast and Kumasi in Ghana. The Eastern Guinean forests, together with the other tropical moist broadleaf forests of West Africa, is i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Pharmacology
Pharmacology is a branch of medicine, biology and pharmaceutical sciences concerned with drug or medication action, where a drug may be defined as any artificial, natural, or endogenous (from within the body) molecule which exerts a biochemical or physiological effect on the cell, tissue, organ, or organism (sometimes the word ''pharmacon'' is used as a term to encompass these endogenous and exogenous bioactive species). More specifically, it is the study of the interactions that occur between a living organism and chemicals that affect normal or abnormal biochemical function. If substances have medicinal properties, they are considered pharmaceuticals. The field encompasses drug composition and properties,functions,sources,synthesis and drug design, molecular and cellular mechanisms, organ/systems mechanisms, signal transduction/cellular communication, molecular diagnostics, interactions, chemical biology, therapy, and medical applications and antipathogenic capabilities. ...

Alkaloids
Alkaloids are a class of basic, naturally occurring organic compounds that contain at least one nitrogen atom. This group also includes some related compounds with neutral and even weakly acidic properties. Some synthetic compounds of similar structure may also be termed alkaloids. In addition to carbon, hydrogen and nitrogen, alkaloids may also contain oxygen, sulfur and, more rarely, other elements such as chlorine, bromine, and phosphorus.Chemical Encyclopedia: alkaloids xumuk.ru Alkaloids are produced by a large variety of organisms including , , |
Strychnos
''Strychnos'' is a genus of flowering plants, belonging to the family Loganiaceae (sometimes Strychnaceae). The genus includes about 100 accepted species of trees and lianas, and more than 200 that are as yet unresolved. The genus is widely distributed around the world's tropics and is noted for the presence of poisonous indole alkaloids in the roots, stems and leaves of various species. Among these alkaloids are the well-known and virulent poisons strychnine and curare. Etymology The name ''strychnos'' was applied by Pliny the Elder in his '' Natural History'' to ''Solanum nigrum''. The word is derived from the Ancient Greek στρύχνον (''strúkhnon'') – "acrid", "bitter". The meaning of the word ''strychnos'' was not fixed in Ancient Greece, where it could designate a variety of different plants having in common the property of toxicity. Distribution The genus has a pantropical distribution. Taxonomy The genus is divided into 12 sections, though it is conceded that ...
