Saccorhiza Polyschides
''Saccorhiza polyschides'', common name furbellow, is a large brown algae of the lower shore and is the largest seaweed found in Europe.Furbellows (''Saccorhiza polyschides'') The Sea Shore, accessed 21 September 2011. Description ''Saccorhiza polyschides'' is a large and bulky seaweed growing to 2 - 4 metres long. The holdfast is a large, bulbous hollow, knobbly structure. The stipe is long, tough, leathery and rigid and is several centimetres wide. Near the base the margin forms several broad, wavy frills. These ruffles tend to dissipate wave energy and lessen the likelihood that it will be torn from the rock. The frond is digitate with about eight large flat lobes and may be massive. The lack of a midrib distinguishes it from '' |
John Lightfoot (biologist)
The Reverend John Lightfoot (9 December 1735 – 20 February 1788) was an English parson-naturalist, spending much of his free time as a conchologist and botanist. He was a systematic and effective curator of the private museum of Margaret Bentinck, Duchess of Portland. He is best known for his ''Flora Scotica'' which pioneered the scientific study of the plants and fungi of Scotland. He was elected a Fellow of the Royal Society for his scientific work. Life and work Lightfoot was born in Newent, Gloucestershire. His father Stephen Lightfoot was a yeoman farmer.Boulger, George Simonds. wikisource:Lightfoot, John (1735-1788) (DNB00), DNB, 1885–1900, Volume 33: Lightfoot, John He was educated at Pembroke College, Oxford.

Edward Batters
Edward is an English given name. It is derived from the Anglo-Saxon name ''Ēadweard'', composed of the elements '' ēad'' "wealth, fortune; prosperous" and '' weard'' "guardian, protector”. History The name Edward was very popular in Anglo-Saxon England, but the rule of the Norman and Plantagenet dynasties had effectively ended its use amongst the upper classes. The popularity of the name was revived when Henry III named his firstborn son, the future Edward I, as part of his efforts to promote a cult around Edward the Confessor, for whom Henry had a deep admiration. Variant forms The name has been adopted in the Iberian peninsula since the 15th century, due to Edward, King of Portugal, whose mother was English. The Spanish/Portuguese forms of the name are Eduardo and Duarte. Other variant forms include French Édouard, Italian Edoardo and Odoardo, German, Dutch, Czech and Romanian Eduard and Scandinavian Edvard. Short forms include Ed, Eddy, Eddie, Ted, Teddy and Ned.

Brown Algae
Brown algae (singular: alga), comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. They are dominant on rocky shores throughout cooler areas of the world. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, ''Macrocystis'', a kelp of the order Laminariales, may reach in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is ''Sargassum'', which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food. Between 1,500 and ...

Alaria Esculenta
''Alaria esculenta'' is an edible seaweed, also known as dabberlocks or badderlocks, or winged kelp. It is a traditional food along the coasts of the far north Atlantic Ocean. It may be eaten fresh or cooked in Greenland, Iceland, Scotland and Ireland. It is the only one of twelve species of '' Alaria'' to occur in both Ireland and in Great Britain. Description Grows to a maximum length of 2 m. The whole frond is brown and consists of a distinct midrib with wavy membranous lamina up to 7 cm wide on either side. The frond is unbranchedDickinson, C.I. (1963). ''British Seaweeds.'' The Kew Series. Eyre & Spottiswoode and tapers towards the end. The base has a short stipe arising from a rhizoidal holdfast. The stipe may bear several sporophylls which are club-shaped and up to 20 cm long and 5 cm broad which bear the spores. It grows from a short cylindrical stipe attached to the rocks by a holdfast of branching root-like rhizoids and grows to about 20 cm ...

Desiccation
Desiccation () is the state of extreme dryness, or the process of extreme drying. A desiccant is a hygroscopic (attracts and holds water) substance that induces or sustains such a state in its local vicinity in a moderately sealed container. Industry Desiccation is widely employed in the oil and gas industry. These materials are obtained in a hydrated state, but the water content leads to corrosion or is incompatible with downstream processing. Removal of water is achieved by cryogenic condensation, absorption into glycols, and absorption onto desiccants such as silica gel. Laboratory A desiccator is a heavy glass or plastic container, now somewhat antiquated, used in practical chemistry for drying or keeping small amounts of materials very dry. The material is placed on a shelf, and a drying agent or ''desiccant'', such as dry silica gel or anhydrous sodium hydroxide, is placed below the shelf. Often some sort of humidity indicator is included in the desiccator to show, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laminaria Hyperborea
''Laminaria hyperborea'' is a species of large brown alga, a kelp in the family Laminariaceae, also known by the common names of tangle and cuvie. It is found in the sublittoral zone of the northern Atlantic Ocean. A variety, ''Laminaria hyperborea f. cucullata'' (P.Svensden & J.M.Kain, 1971) is known from more wave sheltered areas in Scandinavia. Description ''Laminaria hyperborea'' is a massive, leathery seaweed, up to 360 cm long.Newton, L. 1931. ''A Handbook of the British Seaweeds.'' British Museum, London The holdfast is large and cone-shaped, with branched rhizoids, looking rather like a bird's foot. The stipe is circular in cross section, rough, thick at the base and tapering upwards. Older stipes are often covered with epiphytic red algae. The laminate blade is deeply divided into linear segments and is yellowish brown with large digitate segments. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
