Esprit Requien
Esprit Requien (6 May 1788, Avignon – 30 May 1851, Bonifacio, Corse-du-Sud) was a French naturalist, who made contributions in the fields of conchology, paleontology and especially botany. From the age of 18, he was associated with the botanical garden in the city of Avignon. He performed extensive studies of flora native to Corsica and in the environs of Mont Ventoux. During his lifetime, he amassed an herbarium of 300,000 specimens.Prosopo Les sociétés savantes In the fields of conchology and palaeontology, he conducted collecting expeditions to the , and |

Soleirolia Soleirolii
''Soleirolia soleirolii'' (, syn. ''Helxine soleirolii'') is a plant in the nettle family. It has a number of common names, including baby's tears, angel's tears, peace in the home, bits and pieces, bread and cheese, Corsican creeper, Corsican curse, friendship plant, mind-your-own-business, mother of thousands, Paddy's wig, and pollyanna vine. It has also been called Irish moss; however, it is not a moss, nor should it be confused with '' Sagina subulata'' or ''Chondrus crispus'' (an alga), which are also known as "Irish moss". Description It is a delicate-looking creeping herb with juicy bright green or yellow leaves and multitudes of tiny white flowers. It grows close to the ground in mats and is sometimes used in ornamental gardens alongside ferns and other moisture-loving types of plant. The leaves are usually slightly stalked, about 5 mm across. The minute flowers produce oval seeds.Parnell, J. and Curtis, T. 2012. ''Webb's An Irish Flora.'' Cork University Press. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seashells
A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer usually created by an animal or organism that lives in the sea. The shell is part of the body of the animal. Empty seashells are often found washed up on beaches by beachcombers. The shells are empty because the animal has died and the soft parts have decomposed or been eaten by another animal. A seashell is usually the exoskeleton of an invertebrate (an animal without a backbone), and is typically composed of calcium carbonate or chitin. Most shells that are found on beaches are the shells of marine mollusks, partly because these shells are usually made of calcium carbonate, and endure better than shells made of chitin. Apart from mollusk shells, other shells that can be found on beaches are those of barnacles, horseshoe crabs and brachiopods. Marine annelid worms in the family Serpulidae create shells which are tubes made of calcium carbonate cemented onto other surfaces. The ...

Woody Plants
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 opposite to herbaceous plants that die back to the ground until spring. Characteristics Woody plants are usually either 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. Wood is a structural 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 perennials, typically have a dormant period of the year when growth does not take place, in colder climates due to freezing temperatures and lack of daylight during the winter months, in subtropical and tropical climates due to the dry seas ...

World Register Of Marine Species
The World Register of Marine Species (WoRMS) is a taxonomic database that aims to provide an authoritative and comprehensive list of names of marine organisms. Content The content of the registry is edited and maintained by scientific specialists on each group of organism. These taxonomists control the quality of the information, which is gathered from the primary scientific literature as well as from some external regional and taxon-specific databases. WoRMS maintains valid names of all marine organisms, but also provides information on synonyms and invalid names. It is an ongoing task to maintain the registry, since new species are constantly being discovered and described by scientists; in addition, the nomenclature and taxonomy of existing species is often corrected or changed as new research is constantly being published. Subsets of WoRMS content are made available, and can have separate badging and their own home/launch pages, as "subregisters", such as the ''World List of ...

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Requienia (plant)
''Requienia'' is a genus of flowering plants in the family Fabaceae. It includes two species of herbs native to Botswana, Caprivi Strip, Namibia, and Zambia, and the Cape Provinces, Free State (province), Free State and Northern Provinces of South Africa. They grow on sand in dry tropical wooded grassland, shrubland, and bushland in the southern Zambezian region and the Kalahari and Highveld regions. The genus name of ''Requienia'' is in honour of Esprit Requien (1788–1851), who was a French naturalist, who made contributions in the fields of conchology, palaeontology and especially botany. The genus was circumscription (taxonomy), circumscribed by Augustin Pyramus de Candolle in Mem. Fam. Legum. on page 224 in 1825.

Jean-Henri Fabre
Jean-Henri Casimir Fabre (21 December 1823 – 11 October 1915) was a French naturalist, entomologist, and author known for the lively style of his popular books on the lives of insects. Biography Fabre was born on 21 December 1823 in Saint-Léons in Aveyron, France. Fabre was largely an autodidact, owing to the poverty of his family. Nevertheless, he acquired a primary teaching certificate at the young age of 19 and began teaching in Carpentras whilst pursuing further studies. In 1849, he was appointed to a teaching post in Ajaccio (Corsica), then in 1853 moved on to the lycée in Avignon. Fabre was a popular teacher, physicist, chemist and botanist. However, he is probably best known for his findings in the field of entomology, the study of insects, and is considered by many to be the father of modern entomology. Much of his enduring popularity is due to his marvellous teaching ability and his manner of writing about the lives of insects in biographical form, which he pref ...
