Ceramium Howellii
''Ceramium'' is a genus of Ceramium algae (or Rhodophyta). It is a large genus with at least 15 species in the British Isles.''Maggs, C.A. and Hommersand, M.H.'' 1993. ''Seaweeds of the British Isles. vol.1, Rhodophyta Part 3A Ceramiales.'' HMSO & Natural History Museum, London. The fully corticated group previously referred to as ''Ceramium rubrum'', an illegitimate name, is represented, in the British Isles by: '' Ceramium pallidum,'' ''Ceramium botryocarpum'', ''Ceramium nodulosum'' and ''Ceramium secundatum''.Morton, O. 1994. ''Marine Algae of Northern Ireland.'' Ulster Museum. Description All species of ''Ceramium'' are small algae growing to no more than 30 cm (12 in) in length. They consist of a terete monosiphonous axis of cells surrounded by smaller cells forming a cortex. In most species this a continuous cortex enclosing the axis, in others the cortical cells are arranged only in nodes at the junction of cells of the axes. The tips of the branches grow in ...

Dioecious
Dioecy (; ; adj. dioecious , ) is a characteristic of a species, meaning that it has distinct individual organisms (unisexual) that produce male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only about half the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. Dioecy is a dimorphic sexual system, alongside gynodioecy and androdioecy. In zoology In zoology, dioecious species may be opposed to hermaphroditic species, meaning that an individual is either male or female, in which case the synonym gonochory is more often used. Most animal species are dioecious (gon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ireland
Ireland ( ; ga, Éire ; Ulster Scots dialect, Ulster-Scots: ) is an island in the Atlantic Ocean, North Atlantic Ocean, in Northwestern Europe, north-western Europe. It is separated from Great Britain to its east by the North Channel (Great Britain and Ireland), North Channel, the Irish Sea, and St George's Channel. Ireland is the List of islands of the British Isles, second-largest island of the British Isles, the List of European islands by area, third-largest in Europe, and the List of islands by area, twentieth-largest on Earth. Geopolitically, Ireland is divided between the Republic of Ireland (officially Names of the Irish state, named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million living in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islan ...

Fife
Fife (, ; gd, Fìobha, ; sco, Fife) is a council area, historic county, registration county and lieutenancy area of Scotland. It is situated between the Firth of Tay and the Firth of Forth, with inland boundaries with Perth and Kinross (i.e. the historic counties of Perthshire and Kinross-shire) and Clackmannanshire. By custom it is widely held to have been one of the major Pictish kingdoms, known as ''Fib'', and is still commonly known as the Kingdom of Fife within Scotland. A person from Fife is known as a ''Fifer''. In older documents the county was very occasionally known by the anglicisation Fifeshire. Fife is Scotland's third largest local authority area by population. It has a resident population of just under 367,000, over a third of whom live in the three principal towns, Dunfermline, Kirkcaldy and Glenrothes.

Ross And Cromarty
Ross and Cromarty ( gd, Ros agus Cromba), sometimes referred to as Ross-shire and Cromartyshire, is a variously defined area in the Highlands and Islands of Scotland. There is a registration county and a lieutenancy area in current use, the latter of which is in extent. Historically there has also been a constituency of the Parliament of the United Kingdom (1832 to 1983), a local government county (1890 to 1975), a district of the Highland local government region (1975 to 1996) and a management area of the Highland Council (1996 to 2007). The local government county is now divided between two local government areas: the Highland area and Na h-Eileanan Siar (the Western Isles). Ross and Cromarty border Sutherland to the north and Inverness-shire to the south. The county was formed by the uniting of the shires of Ross-shire and Cromartyshire. Both these shires had themselves been formed from the historic province of Ross, out of which the many enclaves and exclaves that forme ...

Faroes
The Faroe Islands ( ), or simply the Faroes ( fo, Føroyar ; da, Færøerne ), are a North Atlantic island group and an autonomous territory of the Kingdom of Denmark. They are located north-northwest of Scotland, and about halfway between Norway ( away) and Iceland ( away). The islands form part of the Kingdom of Denmark, along with mainland Denmark and Greenland. The islands have a total area of about with a population of 54,000 as of June 2022. The terrain is rugged, and the subpolar oceanic climate (Cfc) is windy, wet, cloudy, and cool. Temperatures for such a northerly climate are moderated by the Gulf Stream, averaging above freezing throughout the year, and hovering around in summer and 5 °C (41 °F) in winter. The northerly latitude also results in perpetual civil twilight during summer nights and very short winter days. Between 1035 and 1814, the Faroe Islands were part of the Kingdom of Norway, which was in a personal union with Denmark from 13 ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles.

Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Red Alga Ceramium Tenuicorne
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite 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 and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; 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 brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought ...
