Braun-Blanq.
Josias Braun-Blanquet (3 August 1884 – 20 September 1980) was an influential phytosociologist and botanist. Braun-Blanquet was born in Chur, Switzerland and died in Montpellier, France. Biography Work In Josias Braun-Blanquet's dissertation, supervised by Charles Flahault, he worked on the phytosociology of the southern Cévennes. Subsequently he established the modern way of classifying vegetation according to floristic composition. This is what makes him one of the most influential botanists until today.Nicolson, M. (1993). National Styles, Divergent Classifications: A comparative case study from the history of French and American plant ecology. Knowledge and Society: Studies in the Sociology of Science Past and Present, 8, 139-186. Braun-Blanquet's way of classifying a plant community uses the scientific name of its most characteristic species as namesake, changing the ending of the generic name to "-etum" and treating the specific epithet as adjective. Thus, a particular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oriol De Bolòs
Oriol de Bolòs i Capdevila (born 16 March 1924 in Olot; died 22 March 2007 in Barcelona) was a Spanish botanist, pteridologist, and phytosociologist. He was a specialist in the flora of Catalonia and Spain, and also of the Mediterranean regions, the North Atlantic islands of (Macaronesia) and also Brazil. Background Bolòs came from a family of pharmacists and botanists. Having completed his doctorate in biological sciences, at the Complutense University of Madrid, from 1953 he became professor at the University of Barcelona and from 1965 to 1984 was the director of the Botanical Institute of Barcelona. Joining the Biological Sciences section of the Institute of Catalan Studies in 1964, Bolòs would chair the section between 1989 and 1992. Influenced by Pius Font i Quer and by the founder of the phytosociology Josias Braun-Blanquet, Bolòs would publish ''Les groupements végétaux moyen du bassin de l'Ebre et leur dynamisme'' with Braun-Blanquet in (1958).

Linnean Medal
The Linnean Medal of the Linnean Society of London was established in 1888, and is awarded annually to alternately a botanist or a zoologist or (as has been common since 1958) to one of each in the same year. The medal was of gold until 1976, and is for the preceding years often referred to as "the Gold Medal of the Linnean Society", not to be confused with the official Linnean Gold Medal which is seldom awarded. The engraver of the medal was Charles Anderson Ferrier of Dundee, a Fellow of the Linnean Society from 1882. On the obverse of the medal is the head of Linnaeus in profile and the words Carl Linnaeus, "Carolus Linnaeus", on the reverse are the arms of the society and the legend ''"Societas Linnaeana optime merenti"''; an oval space is reserved for the recipient's name.Gage A.T. and Stearn W.T.

Rhizophora Mangle
''Rhizophora mangle'', the red mangrove, is distributed in Estuary, estuarine ecosystems throughout the tropics. Its Vivipary, viviparous "seeds", in actuality called propagules, become fully mature plants before dropping off the parent tree. These are dispersed by water until eventually embedding in the shallows. ''Rhizophora mangle'' grows on Aerial root#Aerial roots as supports, aerial prop roots, which arch above the water level, giving stands of this tree the characteristic "mangrove" appearance. It is a valuable plant in Florida, Louisiana, and Texas coastal ecosystems. In its native habitat it is threatened by invasive species such as the Brazilian pepper tree ''(Schinus terebinthifolius)''. The red mangrove itself is considered an invasive species in some locations, such as Hawaii, where it forms dense, monoculture, monospecific thickets. ''R. mangle'' thickets, however, provide nesting and hunting habitat for a diverse array of organisms, including fish, birds, and cro ...

Pterocarpus Officinalis
''Pterocarpus officinalis'', the dragonsblood tree, is a species of flowering plant in the family Fabaceae, native to southern Mexico, Central America, the Caribbean, and northern South America.

Scrubland
Shrubland, scrubland, scrub, brush, or bush is a plant community characterized by vegetation dominance (ecology), dominated by shrubs, often also including grasses, Herbaceous plant, herbs, and geophytes. Shrubland may either occur naturally or be the result of human activity. It may be the mature vegetation type in a particular region and remain stable over time, or a transitional community that occurs temporarily as the result of a disturbance, such as fire. A stable state may be maintained by regular natural disturbance such as fire or browsing (predation), browsing. Shrubland may be unsuitable for human habitation because of the danger of fire. The term was coined in 1903. Shrubland species generally show a wide range of adaptations to fire, such as heavy seed production, lignotubers, and fire-induced germination. Botanical structural form In botany and ecology a shrub is defined as a much-branched woody plant less than 8 m high and usually with many Plant stem, stems. T ...

Tropical
The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at N and the Tropic of Capricorn in the Southern Hemisphere at S. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). In terms of climate, the tropics receive sunlight that is more direct than the rest of Earth and are generally hotter and wetter as they aren't affected as much by the solar seasons. The word "tropical" sometimes refers to this sort of climate in the zone rather than to the geographical zone itself. The tropical zone includes deserts and snow-capped mountains, which are not tropical in the climatic sense. The tropics are distinguished from the other climatic and biomatic regions of Earth, which are the middle latitudes and the polar regions on either side of the equatorial zone. The tropics constitute 40% of Earth's surface area and contain 36% of Earth's landmass. , the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Crested Dog's-tail
''Cynosurus cristatus'', the crested dog's-tail, is a short-lived perennial grass in the family Poaceae, characterised by a seed head that is flat on one side. It typically grows in species rich grassland. It thrives in a variety of soil types but avoids the acid and calcareous extremes of pH, and prefers well drained soils. retrieved 10 December 2010.
