Ascophyllum
''Ascophyllum nodosum'' is a large, common cold water seaweed or Phaeophyceae, brown alga (Phaeophyceae) in the Family (biology), family Fucaceae. Its common names include knotted wrack, egg wrack, feamainn bhuí, rockweed, knotted kelp and Norwegian kelp. It grows only in the northern Atlantic Ocean, along the north-western coast of Europe (from the White Sea to Portugal) including east Greenland and the north-eastern coast of North America. Its range further south of these latitudes is limited by warmer ocean waters. It dominates the intertidal zone. ''Ascophyllum nodosum'' has been used numerous times in scientific research and has even been found to benefit humans through consumption. Scientific name history ''Ascophyllum nodosum'' is the only species in the genus ''Ascophyllum''. The original name (basionym) was ''Fucus nodosus'' Carl Linnaeus, Linnaeus 1753. The species was transferred to the genus ''Ascophyllum'' (as ''Ascophylla'') by Stackhouse (Papenfuss 1950), under th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fucus
''Fucus'' is a genus of brown algae found in the intertidal zones of rocky seashores almost throughout the world. Description and life cycle The thallus is perennial with an irregular or disc-shaped holdfast or with haptera. The erect portion of the thallus is dichotomous or subpinnately branched, flattened and with a distinct midrib. Gas-filled pneumatocysts (air- vesicles) are present in pairs in some species, one on either side of the midrib. The erect portion of the thallus bears cryptostomata and caecostomata (sterile surface cavities). The base of the thallus is stipe-like due to abrasion of the tissue lateral to the midrib and it is attached to the rock by a holdfast. The gametangia develop in conceptacles embedded in receptacles in the apices of the final branches. They may be monoecious or dioecious. These algae have a relatively simple life cycle and produce only one type of thallus which grows to a maximum size of 2 m. Fertile cavities, the conceptacle ...

Seaweed
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of ''Rhodophyta'' (red), '' Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon and producing at least 50% of Earth's oxygen. Natural seaweed ecosystems are sometimes under threat from human activity. For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; for example, a wasting disease in predators of purple urchins has led to an urchin population surge which has destroyed large kelp forest regions off the coast of California. Humans have a long history of cultivating seaweeds for their uses. In recent years, seaweed farming has become a global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phaeophyceae
Brown algae (: alga) are a large group of multicellular algae comprising the class Phaeophyceae. They include many seaweeds located in colder waters of the Northern Hemisphere. Brown algae are the major seaweeds of the temperate and polar regions. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. 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 that 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. Some members of the class, such as kelps, are used by humans as food. Between 1,500 and 2,000 species of brown algae are known worldwide. Some species, such as '' Ascophyllum nodosum' ...

Larne Lough
Larne Lough, historically Lough Larne (), is a sea loch or inlet in County Antrim, Northern Ireland. It lies between the Islandmagee peninsula and the mainland. At its mouth is the town of Larne. It is designated as an area of special scientific interest, a special protection area, and a Ramsar site to protect the wetland environment, particularly due to the presence of certain bird species and shellfish. Name The lough takes its name from the small medieval territory of Latharna meaning "descendants of Lathair". The older name for the lough was ''Loch Ollarbha'' or ''Inbhear nOllarbha'', from ''Ollarbha'', the ancient name of the Larne Water. Places of interest Chaine Memorial Tower lighthouse is on the west side of the entrance to Larne Lough. Flora and fauna In 1929, a "Coastal Survey" of the algae of the north-east of Ireland was begun when a few members of the Botanical Society in The Queen's University of Belfast investigated and mapped the distribution of the seaweeds ...

John Stackhouse (botanist)
John Stackhouse (1742 – 22 November 1819) was an English botanist, primarily interested in spermatophytes, algae and mycology. He was born in Probus, Cornwall, and built Acton Castle, above Stackhouse Cove, Cornwall, in order to further his studies about the propagation of algae from their spores. He was the author of ''Nereis Britannica; or a Botanical Description of British Marine Plants, in Latin and English, accompanied with Drawings from Nature'' (1797). Personal life The second son of William Stackhouse, D.D. (d. 1771), rector of St. Erme, Cornwall, and nephew of Thomas Stackhouse, he was born at Trehane, Probus, in Cornwall. On 20 June 1758 he matriculated at Exeter College, Oxford, and was a Fellow of the college from 1761 to 1764. On succeeding his relative, Mrs. Grace Percival, sister of Sir William Pendarves, in the Pendarves estates in 1763, he resigned his fellowship, and, after travelling abroad for two or three years, settled on his newly acquired property.

Frond
A frond is a large, divided leaf. In both common usage and botanical nomenclature, the leaves of ferns are referred to as fronds and some botanists restrict the term to this group. Other botanists allow the term frond to also apply to the large leaves of cycads, as well as palms (Arecaceae) and various other flowering plants, such as mimosa or sumac. "Frond" is commonly used to identify a large, compound leaf, but if the term is used botanically to refer to the leaves of ferns and algae it may be applied to smaller and undivided leaves. Fronds have particular terms describing their components. Like all leaves, fronds usually have a stalk connecting them to the main stem. In botany, this leaf stalk is generally called a Petiole (botany), petiole, but in regard to fronds specifically it is called a Stipe (botany), stipe, and it supports a flattened blade (which may be called a lamina), and the continuation of the stipe into this portion is called the rachis. The blades may be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
