Dombeya Acutangula
''Dombeya acutangula'', the bois bete or ''mahot tantan'', is a species of flowering plant in the family Malvaceae. It is native to the Mascarene Islands (Mauritius, Réunion, and Rodrigues), and Madagascar, Malawi, Mozambique, Tanzania, and Zambia. It has charming pale (white or light pink) flowers in small clusters. On Mauritius it grows in forests from 300 to 500 meters elevation. It is almost extinct on the island due to habitat loss; some 50 plants remain in the wild, growing in a narrowly circumscribed area at Corps de garde, Trois Mamelles, Yemen, Magenta and Chamarel. Systematics Bois bete was sometimes placed in ''Pentapetes''. It is somewhat variable and thus was described under a number of names, which are now considered junior synonyms: * ''Pentapetes acutangula'' Poir. * ''Pentapetes angulosa'' Poir. * ''Pentapetes palmata'' Poir. This species is rather isolated among its congeners and may belong to the more basal members of its genus. It differs both from the " ...

Antonio José Cavanilles
Antonio José Cavanilles (16 January 1745 – 5 May 1804) was a leading Spanish taxonomic botanist, artist and one of the most important figures in the 18th century period of Enlightenment in Spain. Cavanilles is most famous for his 2-volume book on Spanish flora, published in 1795 and titled ‘Observations on the Natural History, Geography and Agriculture of the Kingdom of Valencia’.He named many plants, particularly from Oceania. He named at least 100 genera, about 54 of which were still used in 2004, including ''Dahlia'', '' Calycera'', '' Cobaea'', '' Galphimia'', and '' Oleandra''. Biography Cavanilles was born in Valencia. He lived in Paris from 1777 to 1781, where he followed careers as a clergyman and a botanist, thanks to André Thouin and Antoine Laurent de Jussieu. He was one of the first Spanish scientists to use the classification method invented by Carl Linnaeus. Early life and education Antonio José Cavanilles was born on January 16, 1745, in Valenc ...

Dombeya Ciliata
''Dombeya'' is a flowering plant genus. Traditionally included in the family (biology), family Sterculiaceae, it is included in the expanded Malvaceae in the Angiosperm Phylogeny Group, APG and most subsequent systematics. These plants are known by a number of vernacular names which sometimes, misleadingly, allude to the superficial similarity of flowering ''Dombeya'' to pears or hydrangeas (which are unrelated). Therefore, the genus as a whole is often simply called dombeyas. The name of a biological genus, generic name commemorates Joseph Dombey (1742–1794), a French botanist and explorer in South America, involved in the notorious "Dombey affair", embroiling scientists and governments of France, Spain, and Britain for more than two years. Distribution These plants grow chiefly throughout Africa and Madagascar. Madagascar has the majority of species, with approximately 175 native species. 19 are found on the African mainland, with one, ''Dombeya torrida'', also extending into ...

Rainforest
Rainforests are forests characterized by a closed and continuous tree Canopy (biology), canopy, moisture-dependent vegetation, the presence of epiphytes and lianas and the absence of wildfire. Rainforests can be generally classified as tropical rainforests or temperate rainforests, but other types have been described. Estimates vary from 40% to 75% of all biotic community, biotic species being Indigenous (ecology), indigenous to the rainforests. There may be many millions of species of plants, insects and microorganisms still undiscovered in tropical rainforests. Tropical rainforests have been called the "jewels of the Earth" and the "medicine chest (idiom), world's largest pharmacy", because over one quarter of natural medicines have been discovered there. Rainforests as well as endemic rainforest species are rapidly disappearing due to #Deforestation, deforestation, the resulting habitat loss and air pollution, pollution of the atmosphere.

Xeric
Deserts and xeric shrublands are a biome defined by the World Wide Fund for Nature. Deserts and xeric (Ancient Greek 'dry') shrublands form the largest terrestrial biome, covering 19% of Earth's land surface area. Ecoregions in this habitat type vary greatly in the amount of annual rainfall they receive, usually less than annually except in the margins. Generally evaporation exceeds rainfall in these ecoregions. Temperature variability is also diverse in these lands. Many deserts, such as the Sahara, are hot year-round, but others, such as East Asia's Gobi Desert, become quite cold during the winter. Temperature extremes are a characteristic of most deserts. High daytime temperatures give way to cold nights because there is no insulation provided by humidity and cloud cover. The diversity of climatic conditions, though quite harsh, supports a rich array of habitats. Many of these habitats are ephemeral in nature, reflecting the paucity and seasonality of available water. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basal (biology)
In phylogenetics, basal is the direction of the ''base'' (or root) of a rooted phylogenetic tree or cladogram. The term may be more strictly applied only to nodes adjacent to the root, or more loosely applied to nodes regarded as being close to the root. Note that extant taxa that lie on branches connecting directly to the root are not more closely related to the root than any other extant taxa. While there must always be two or more equally "basal" clades sprouting from the root of every cladogram, those clades may differ widely in taxonomic rank, species diversity, or both. If ''C'' is a basal clade within ''D'' that has the lowest rank of all basal clades within ''D'', ''C'' may be described as ''the'' basal taxon of that rank within ''D''. The concept of a ' key innovation' implies some degree of correlation between evolutionary innovation and diversification. However, such a correlation does not make a given case predicable, so ancestral characters should not be imputed to t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conspecificity
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and soci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junior Synonym
In taxonomy, the scientific classification of living organisms, a synonym is an alternative scientific name for the accepted scientific name of a taxon. The botanical and zoological codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that now goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called '' Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank – for example, the name ''Papilio prorsa'' Linnaeus, ...
