Mullion Island
Mullion Island ( kw, Enys Pryven, meaning ''worm island'') is an uninhabited island on the eastern side of Mount's Bay, Cornwall, in the United Kingdom. It is approximately half a mile (0.8 km) offshore from Mullion Cove, in circumference and the highest point is above sea level. It forms part of the Lizard Peninsula Area of Outstanding Natural Beauty and is within the Mullion Cliff to Predannack Cliff Site of Special Scientific Interest. Geography and Geology The rocks of the island were formed 350 million years ago, with most formed in a fashion similar to the mid-Atlantic ridge today, where lava flows from an under-water split in the Earth's crust, and cools rapidly on the sea-bed as basalt, forming large rounded lumps known as pillow lava, many with a chilled margin. Mullion Island was formed by a separate (later) volcanic episode than the nearby Lizard complex rocks. The soils, developed from the underlying basalt and slate, has been highly manured by bird droppings, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosphate
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one or two protons gives the dihydrogen phosphate ion and the hydrogen phosphate ion ion, respectively. These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.

An example is trimethyl phosphate, . The term also refers to the triv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viscount Clifden
Viscount Clifden, of Gowran in the County of Kilkenny, Ireland, was a title in the Peerage of Ireland. It was created on 12 January 1781 for James Agar, 1st Baron Clifden. He had already been created Baron Clifden, of Gowran in the County of Kilkenny, in 1776, also in the Peerage of Ireland. The Viscounts also held the titles of Baron Mendip in the Peerage of Great Britain from 1802 to 1974 (a title which is still extant and now held by the Earl of Normanton) and Baron Dover from 1836 to 1899, when this title became extinct, and ''Baron Robartes'' from 1899 to 1974, when this title became extinct, the two latter titles which were in the Peerage of the United Kingdom. The interrelated histories of the peerages follow below. Viscount Clifden James Agar, 1st Viscount Clifden was the son of Henry Agar of Gowran Castle and the elder brother of Charles Agar, 1st Earl of Normanton. His mother was Anne Ellis, daughter of Welbore Ellis, Bishop of Meath, and sister of the politician ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huer
In England, English fishing customs, a conder, also called a huer or bulker, was a person who stood on high places near the sea coast in times of herring-fishing to signal to the fishers which way the shoal of herrings or pilchards passed—their course being more discernible to those who stand on high cliffs, due to the blue colour they cause in the water, than to those aboard vessels. In Cornwall, the huer would shout 'Hevva!, Hevva!' to alert the boats to the location of the pilchard shoals. The term was also used to refer to the raised location where a conder stood.

Seine Fishing
Seine fishing (or seine-haul fishing; ) is a method of fishing that employs a surrounding net, called a seine, that hangs vertically in the water with its bottom edge held down by weights and its top edge buoyed by floats. Seine nets can be deployed from the shore as a beach seine, or from a boat. Boats deploying seine nets are known as seiners. Two main types of seine net are deployed from seiners: ''purse seines'' and ''Danish seines''. A seine differs from a gillnet, in that a seine encloses fish, where a gillnet directly snares fish. Etymology The word ''seine'' has its origins in the Old English ''segne'', which entered the language via Latin ''sagena'', from the original Greek σαγήνη ''sagēnē'' (a drag-net). History Seines have been used widely in the past, including by Stone Age societies. For example, the Māori used large canoes to deploy seine nets which could be over a kilometer long. The nets were woven from green flax, with stone weights and light wood o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sardine
"Sardine" and "pilchard" are common names for various species of small, oily forage fish in the herring family Clupeidae. The term "sardine" was first used in English during the early 15th century, a folk etymology says it comes from the Italian island of Sardinia, around which sardines were once supposedly abundant. The terms "sardine" and "pilchard" are not precise, and what is meant depends on the region. The United Kingdom's Sea Fish Industry Authority, for example, classifies sardines as young pilchards. One criterion suggests fish shorter in length than are sardines, and larger fish are pilchards. The FAO/WHO Codex standard for canned sardines cites 21 species that may be classed as sardines. FishBase, a comprehensive database of information about fish, calls at least six species "pilchard", over a dozen just "sardine", and many more with the two basic names qualified by various adjectives. Etymology 'Sardine' first appeared in English in the 15th century, a loanword ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phalacrocorax Carbo
The great cormorant (''Phalacrocorax carbo''), known as the black shag in New Zealand and formerly also known as the great black cormorant across the Northern Hemisphere, the black cormorant in Australia, and the large cormorant in India, is a widespread member of the cormorant family of seabirds. The genus name is Latinised Ancient Greek, from φαλακρός (''phalakros'', "bald") and κόραξ (''korax'', "raven"), and ''carbo'' is Latin for "charcoal". It breeds in much of the Old World, Australia, and the Atlantic coast of North America. Taxonomy and etymology The long white-breasted cormorant ''P. c. lucidus'' found in sub-Saharan Africa, has a white neck and breast. It is often treated as a full species, ''Phalacrocorax lucidus'' (e.g. , ). In addition to the Australasian and African forms, ''Phalacrocorax carbo novaehollandiae'' and ''P. c. lucidus'' mentioned above, other geographically distinct subspecies are recognised, including ''P. c. sinensis'' (western Europ ...

Gulosus Aristotelis
The European shag or common shag (''Gulosus aristotelis'') is a species of cormorant. It is the only member of the Monotypic taxon, monotypic genus ''Gulosus''. It breeds around the rocky coasts of western and southern Europe, southwest Asia and north Africa, mainly bird migration, wintering in its breeding range except for the northernmost birds. In United Kingdom, Britain this seabird is usually referred to as simply the shag. The scientific genus name derives from the Latin for glutton. The species name ''aristotelis'' commemorates the Greek philosopher Aristotle. Taxonomy The European shag was formerly classified within the genus ''Phalacrocorax'', but a 2014 study found it to be significantly more diverged than the clade containing ''Phalacrocorax'' and ''Urile'', but Basal (phylogenetics), basal to the clade containing ''Nannopterum'' and ''Blue-eyed shag, Leucocarbo'', and thus classified it in its own genus, ''Gulosus''.

Alca Torda
The razorbill, razor-billed auk, or lesser auk (''Alca torda'') is a colonial seabird and the only extant member of the genus '' Alca'' of the family Alcidae, the auks. It is the closest living relative of the extinct great auk (''Pinguinis impennis''). Wild populations live in the subarctic waters of the Atlantic Ocean. Razorbills are primarily black with a white underside. The male and female are identical in plumage; however, males are generally larger than females. This agile bird, which is capable of both flight and diving, has a predominantly aquatic lifestyle and only comes to land in order to breed. It is monogamous, choosing one partner for life. Females lay one egg per year. Razorbills nest along coastal cliffs in enclosed or slightly exposed crevices. The parents spend equal amounts of time incubating, and once the chick has hatched, they take turns foraging for their young. In 1918, the razorbill was protected in the United States by the Migratory Bird Treaty Act. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haematopus Ostralegus
The Eurasian oystercatcher (''Haematopus ostralegus'') also known as the common pied oystercatcher, or palaearctic oystercatcher, or (in Europe) just oystercatcher, is a wader in the oystercatcher bird family Haematopodidae. It is the most widespread of the oystercatchers, with three races breeding in western Europe, central Eurosiberia, Kamchatka, China, and the western coast of Korea. No other oystercatcher occurs within this area. The extinct Canary Islands oystercatcher (''Haematopus meadewaldoi''), formerly considered a distinct species, may have actually been an isolated subspecies or distinct population of the Eurasian oystercatcher. This oystercatcher is the national bird of the Faroe Islands. Taxonomy The Eurasian oystercatcher was listed by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Haemotopus ostralegus''. The genus name ''Haematopus'' combines the Ancient Greek ''haima'' αἳμα meaning " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uria Aalge
The common murre or common guillemot (''Uria aalge'') is a large auk. It has a circumpolar distribution, occurring in low-Arctic and boreal waters in the North Atlantic and North Pacific. It spends most of its time at sea, only coming to land to breed on rocky cliff shores or islands. Common murres have fast direct flight but are not very agile. They are more maneuverable underwater, typically diving to depths of . Depths of up to have been recorded. Common murres breed in colonies at high densities. Nesting pairs may be in bodily contact with their neighbours. They make no nest; their single egg is incubated on a bare rock ledge on a cliff face. Eggs hatch after ~30 days incubation. The chick is born downy and can regulate its body temperature after 10 days. Some 20 days after hatching the chick leaves its nesting ledge and heads for the sea, unable to fly, but gliding for some distance with fluttering wings, accompanied by its male parent. Male guillemots spend more time di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
