Jean Vincent Félix Lamouroux
Jean Vincent Félix Lamouroux (3 May 1779 – 26 March 1825) was a French biologist and naturalist, noted for his seminal work with algae. Biography Lamouroux was born in Agen in the Aquitaine of southwestern France, the son of Claude Lamouroux, an intellectual who made his livelihood in manufacturing, but who was also a musician, a one-term mayor of Agen, and a co-founder of the Academic Society of Agen. Jean Vincent Lamouroux studied botany at the Boudon de Saint-Amans school in Agen. Lamouroux was particularly interested in marine organisms such as algae and hydrozoans. In 1805 he published a dissertation on several species of ''Fucus'' before settling in Paris in 1807, after his father went into bankruptcy. In 1807, Lamouroux was appointed to the French Academy of Sciences and in 1808 he became assistant professor of natural history at the University of Caen, rising to full professorship by 1811. He joined the Linnean Society of Calvados and contributed to its publications, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Red Algae Genera
Red is the color at the long wavelength end of the visible spectrum of light, next to Orange (colour), orange and opposite Violet (color), violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged Scarlet (color), scarlet and Vermilion, vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy (color), burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayan civilization, Mayans colored their faces red in ceremonies; Roman Empire, Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brillian ...
