John Hutchinson (botanist)
John Hutchinson (7 April 1884 Blindburn, Northumberland – 2 September 1972 London) was an English botanist, taxonomist and author.''A Botanist in Southern Africa'' John Hutchinson (London, 1946) Life and career Born in Blindburn, Wark on Tyne, Northumberland, England, he received his horticultural training in Northumberland and Durham, England, Durham and was appointed a student gardener at Royal Botanic Gardens, Kew, Kew in 1904. His taxonomic and drawing skills were soon noticed and resulted in his being appointed to the Herbarium in 1905. He moved from assistant in the Indian section to assistant for Tropical Africa, returning to Indian botany from 1915 to 1919, and from then on was in charge of the African section until 1936 when he was appointed Keeper of the Museums of Botany at Kew. He retired in 1948 but continued working on the phylogeny of flowering plants and publishing two parts of ''The Genera of Flowering Plants''. John Hutchinson proposed a Hutchinson system, ...

John McEwan Dalziel
John McEwan Dalziel (1872–1948) was a British physician, botanist, and plant collector. He was born in Nagpur, India in 1872. He served as a medical missionary in China from 1895 to 1902, and afterwards joined the West African Medical Service and became a forest officer from 1905 to 1922. From 1923 he was employed at the Royal Botanic Gardens, Kew, and from 1925 to 1927 he joined the botanical expedition aboard the research vessel ''Utowana'' led by botanist David G. Fairchild and funded by philanthropist Allison Vincent Armour. Dalziel also served as the vessel's medical officer. The Fairchild expeditions of visited Sri Lanka, Sumatra and Java in 1926, and coastal West Africa, from Gambia to Bioko, in 1927. Dalziel was active as a plant collector from 1895 to 1927, and collected in China and in present-day Cameroon, Gambia, Ghana, Guinea, Liberia, Niger, Nigeria, and Sierra Leone in tropical Africa.

Woody Plant
A woody plant is a plant that produces wood as its structural tissue and thus has a hard stem. In cold climates, woody plants further survive winter or dry season above ground, as opposed to Herbaceous plant, herbaceous plants that die back to the ground until Spring (season), spring. Characteristics Woody plants are usually trees, shrubs, or lianas. These are usually perennial plants whose stems and larger roots are reinforced with wood produced from secondary xylem. The main stem, larger branches, and roots of these plants are usually covered by a layer of Bark (botany), bark. Wood is a structural cell (biology), tissue that allows woody plants to grow from above ground stems year after year, thus making some woody plants the largest and tallest terrestrial plants. Woody plants, like Herbaceous plant, herbaceous perennials, typically have a Dormancy, dormant period of the year when growth does not take place. This occurs in Temperate climate, temperate and Continental clima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lecythidaceae
The Lecythidaceae ( ) comprise a family of about 20 genera and 250–300 species of woody plants native to tropical South America, Africa (including Madagascar), Asia and Australia. Well known members of the family include the cannonball tree (''Couroupita guianensis'') and the edible Brazil nut (''Bertholletia excelsa''). Taxonomy According to molecular analysis of Lecythidaceae, including work by Mori ''et al.'' (2007), subfamilies include: Barringtonioidea Previously Barringtoniaceae; also ''sensu'' Takhtajan 1997; this subfamily was also called Planchonioideae (which included ''Barringtonia'').

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] |

Endemic Flora Of Nigeria
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 becoming ...

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 ...

Taxa Named By John Hutchinson (botanist)
In biology, a taxon ( back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
