Terminalia Reitzii
''Terminalia reitzii'' is a species of plant in the Combretaceae family. It is endemic to Brazil, growing primarily in seasonally dry tropical forests in the southern part of the country. It is threatened by habitat loss Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease ....

Arthur Wallis Exell
Arthur Wallis Exell OBE (21 May 1901 in Birmingham – 15 January 1993 in Cheltenham) was initially an assistant and later Deputy Keeper of Botany at the British Museum during the years 1924–1939 and 1950–1962. A noted cryptographer, taxonomist and phytogeographer, he was notable for his furthering of botanical exploration in tropical and sub-tropical Africa, and was an authority on the family Combretaceae. Exell's formal education started at Queen Elizabeth Grammar School in Warwickshire, and then King Edmund's School in Birmingham. From there he went on to Emmanuel College, Cambridge and was awarded an M.A. in 1926, having joined the British Museum as a second-class assistant on 11 August 1924, eventually becoming Deputy Keeper of Botany in 1950. He was entrusted with the Polypetalae, although his first paper was a morphological study of the hymenium in three species of fungus. Exell's first contact with Africa was in 1932/3 when he travelled to the islands in the Gulf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Combretaceae
The Combretaceae, often called the white mangrove family, are a family of flowering plant Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed with ...s in the order Myrtales. The family includes about 530 species of trees, shrubs, and lianas in 10 genera. The family includes the leadwood tree, '' Combretum imberbe''. Three genera, '' Conocarpus'', '' Laguncularia'', and '' Lumnitzera'', grow in mangrove habitats (mangals). The Combretaceae are widespread in the subtropics and tropics. Some members of this family produce useful construction timber, such as idigbo from '' Terminalia ivorensis''. The commonly cultivated '' Quisqualis indica'' (as well as the entire former genus ''Quisqualis'') is now placed in the genus '' Combretum''. Many plants in the former ''Quisqualis'' genus contain t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Seasonal Tropical Forest
Seasonal tropical forest, also known as moist deciduous, semi-evergreen seasonal, tropical mixed or monsoon forest, typically contains a range of tree species: only some of which drop some or all of their leaves during the dry season. This tropical forest is classified under the Walter system as (i) tropical climate with high overall rainfall (typically in the 1000–2500 mm range; 39–98 inches) and (ii) having a very distinct wet season with (an often cooler “winter”) dry season. These forests represent a range of habitats influenced by monsoon (Am) or tropical wet savanna (Aw/As) climates (as in the Köppen climate classification). Drier forests in the Aw/As climate zone are typically deciduous and placed in the Tropical dry forest biome: with further transitional zones ( ecotones) of savannah woodland then tropical and subtropical grasslands, savannas, and shrublands. Distribution Seasonal (mixed) tropical forests can be found in many parts of the tropical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Terminalia (plant)
''Terminalia'' is a genus of large trees of the flowering plant family Combretaceae, comprising nearly 300 species distributed in Tropics, tropical regions of the world. The genus name derives from the Latin word ''terminus'', referring to the fact that the leaves appear at the very tips of the shoots. Terminalia latifolia, Axlewood (''T. latifolia'') is used for its wood and tannins and as a fodder. Terminalia leiocarpa, African birch (''T. leiocarpa'') is used for its wood and to make yellow dye and medicinal compounds. A yellow dyestuff produced from the leaves of ''T. leiocarpa'' has traditionally been used in West Africa to dye leather. Selected species There are 278 accepted ''Terminalia'' species as of July 2024 according to Plants of the World Online. Selected species include: *''Terminalia acuminata'' (Fr. Allem.) Eichl. *''Terminalia albida'' Scott-Elliot *''Terminalia amazonia'' (J.F.Gmel.) Exell – white olive *''Terminalia anogeissiana'' – axlew ...

Taxonomy Articles Created By Polbot
280px, Generalized scheme of taxonomy Taxonomy is a practice and science concerned with classification or categorization. Typically, there are two parts to it: the development of an underlying scheme of classes (a taxonomy) and the allocation of things to the classes (classification). Originally, taxonomy referred only to the classification of organisms on the basis of shared characteristics. Today it also has a more general sense. It may refer to the classification of things or concepts, as well as to the principles underlying such work. Thus a taxonomy can be used to organize species, documents, videos or anything else. A taxonomy organizes taxonomic units known as "taxa" (singular "taxon"). Many are hierarchies. One function of a taxonomy is to help users more easily find what they are searching for. This may be effected in ways that include a library classification system and a search engine taxonomy. Etymology The word was coined in 1813 by the Swiss botanist A ...
