Fucus Tendo
''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 conceptacles, co ...

Fucus Serratus
''Fucus serratus'' is a seaweed of the north Atlantic Ocean, known as toothed wrack or serrated wrack. Description and reproduction ''Fucus serratus'' is a robust alga, olive-brown in colour and similar to '' Fucus vesiculosus'' and ''Fucus spiralis''. It grows from a discoid holdfast up to long. The fronds are flat, about wide, bifurcating, and up to long including a short stipe. It branches irregularly and dichotomously. The flattened blade has a distinct midrib and is readily distinguished from related taxa by the serrated edge of the fronds. It does not have air vesicles, such as are found in ''F. vesiculosus'', nor is it spirally twisted like ''F. spiralis''. Male and female receptacles are on different plants. The lamina shows cryptostomata – small cavities which produce colourless hairs. The reproductive bodies form in conceptacles sunken in receptacles towards the tips on the branches. In these conceptacles oogonia and antheridia are produced and after ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fucus Radicans
''Fucus radicans'' is a species of brown algae in the family Fucaceae, endemic to and recently evolved within the Baltic Sea. The species was first described by Lena Bergström and Lena Kautsky in 2005 from a location in Ångermanland, Sweden. The specific epithet is from the Latin and means "rooting", referring to the fact that this species primarily reproduces by the taking root of detached fragments. ''Fucus radicans'' seems to have diverged from the closely related and widely distributed ''Fucus vesiculosus'' within about the last 400 years. It often reproduces clonally, which may have helped its rapid emergence as a new species. Genetic analysis supports the hypothesis of the recent divergence of ''Fucus radicans'' from ''Fucus vesiculosus'' as an example of sympatric speciation, with the two species presently occupying the same semi-marine territory. Description ''Fucus radicans'' is morphologically similar to bladderwrack (''Fucus vesiculosus'') which is dichotomou ...

Simón De Roxas Clemente Y Rubio
Simón de Roxas Cosme Damián Clemente y Rubio (27 September 1777, in Titaguas ( Valencia, Spain) – 27 February 1827, in Madrid) was a renowned Spanish botanist, considered to be the father of Spanish ampelography. Biography Early Days Born into a numerous family of 15 siblings (only six of which survived to adulthood) Simón de Rojas was a son of Joaquín Clemente Collado and his second wife, Juliana Rubio Polo, and was fourth in line in term of inheritance and thus only had a very slight possibility of inheriting the family notary business. At the age of 10 he entered the seminary of Segorbe, and after studying humanities for four years he was sent to Valencia to continue his secondary education. There he studied philosophy with Antonio Galiana and became an arts professor. He also studied other subjects in the ecclesiastical curriculum and he excelled in philology especially Greek, Hebrew and Latin. However, he was more attracted to the natural sciences and he put toge ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Fucus Gardneri
''Fucus gardneri'' is a species of seaweed, a brown alga living on the littoral shore of the Pacific coasts of North America. It has the common names of rockweed and bladderwrack. Description ''Fucus gardneri'' is olive brown in colour and similar to ''Fucus spiralis''. It grows to long and branches somewhat irregularly dichotomous and is attached, generally to rock, by a discoid holdfast. It has airsacks at the top. Life history The tips of mature individuals swell up and provide flotation for the plant as well as reproductive chambers for developing sperm and eggs. During low tide, the swollen tips dry up squeezing out sperm and eggs which unite into a zygote during the next flood tide and settle onto a substratum. Ecology Rockweed can form thick bands in the middle intertidal on rocky substrates. The other common species of ''Fucus'': ''Fucus spiralis'', '' Fucus vesiculosus'' and '' Fucus serratus'' along with ''Ascophyllum nodosum'' form the main and dominant sea ...
