Skokholm
Skokholm () or Skokholm Island is an island off the coast of Pembrokeshire, Wales, south of the neighbouring island of Skomer. The surrounding waters are a marine reserve and all are part of the Pembrokeshire Coast National Park. Both islands are listed as Sites of Special Scientific Interest. Geography Skokholm is long and wide, covering . Made up of Old Red Sandstone, its cliffs stand between in the northeast, to in the southwest. Battered by storms, the high cliffs and isolated nature of the island make it a haven for seabirds. There is a rock outcrop close to the centre of the island, which provides shelter to the island's only structures. Its greatest height is 55 metres (180 feet). History Whilst no trees grow on the island in modern times, Skokholm is possibly Norse for "wooded island", a combination of ''skógr'' (wood, modern Norwegian: ''skog'') and ''holmr'' (small island, middle English ''holm'' and modern Norwegian ''holme''), named by the Vikings.

Ronald Lockley
Ronald Mathias Lockley (8 November 1903 – 12 April 2000) was a Welsh ornithologist and naturalist. He wrote over fifty books on natural history, including a major study of shearwaters, and many articles. He is perhaps best known for his book ''The Private Life of the Rabbit''. Life and career Lockley was born in Cardiff and grew up in the suburb of Whitchurch where his mother ran a boarding school. While still at school, he spent his weekends and summer holidays living rough in the woods and wetlands that now form the Glamorganshire Canal local nature reserve. After leaving school, he established a small poultry farm with his sister near St Mellons, Cardiff. His son is the palaeontologist Martin Lockley. Skokholm In 1927, with his first wife Doris Shellard, he took a 21-year lease of Skokholm, a small island some off the western tip of Pembrokeshire, which was inhabited only by rabbits and seabirds. Attempts to make a living from catching and selling rabbits and breed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pembrokeshire
Pembrokeshire ( ; cy, Sir Benfro ) is a Local government in Wales#Principal areas, county in the South West Wales, south-west of Wales. It is bordered by Carmarthenshire to the east, Ceredigion to the northeast, and the rest by sea. The county is home to Pembrokeshire Coast National Park. The Park occupies more than a third of the area of the county and includes the Preseli Hills in the north as well as the Pembrokeshire Coast Path. Historically, mining and fishing were important activities, while industry nowadays is focused on agriculture (86 per cent of land use), oil and gas, and tourism; Pembrokeshire's beaches have won many awards. The county has a diverse geography with a wide range of geological features, habitats and wildlife. Its prehistory and modern history have been extensively studied, from tribal occupation, through Roman times, to Welsh, Irish, Norman, English, Scandinavian and Flemish influences. Pembrokeshire County Council's headquarters are in the county ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wildlife Trust Of South And West Wales
The Wildlife Trust of South and West Wales (WTSWW) ( cy, Ymddiriedolaeth Natur De a Gorllewin Cymru) is a Wildlife Trust in south and west Wales, one of 46 such Trusts in the United Kingdom. History Forerunner of the WTSWW, the former West Wales Naturalists' Trust traces its origin to a meeting held in Haverfordwest in February 1938. It was convened by L. D. Whitehead, the Welsh industrialist and owner of Ramsey, and the naturalist and author R. M. Lockley, then living on Skokholm. Seventy-eight people were present at that inaugural meeting and on the motion of Mr. Hugh Lloyd-Philipps, of Dale Castle, the Pembrokeshire Bird Protection Society was formed. In 1943, the society was urged to promote the establishment of nature reserves in readiness for post-war conditions. A meeting in 1945 decided to widen its area, so as to cover the counties of Pembroke, Carmarthen, Cardigan, and Merioneth, in compliance with requests from those counties, and considered a selection of alterna ...

Razorbill
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. Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dale Castle
Dale Castle is a 13th-century castle located close to the village of Dale in Pembrokeshire, Wales. In 1910, part of the castle was removed and other parts were incorporated into a new private dwelling house, built in the style of a fortified manor house. History Built after the Norman invasion of South Wales, the castle was originally built by the de Vales, descendants of a knight who had accompanied Robert fitz Martin on his invasion of north Pembrokeshire. The male line died out, meaning that subsequent owners have rotated through the female bloodline. The Walter family of Roch Castle took ownership, from whom Lucy Walter, mistress of King Charles II and mother of the Duke of Monmouth was descended. It was then owned by the families of the Paynters, Allens and Lloyds. The site Little remains of the original medieval castle and what there is was largely remodelled and incorporated into the present modern house and farm in 1910. In an illustration dating from around 1810, a re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

Silurian
The Silurian ( ) is a geologic period and system spanning 24.6 million years from the end of the Ordovician Period, at million years ago ( Mya), to the beginning of the Devonian Period, Mya. The Silurian is the shortest period of the Paleozoic Era. As with other geologic periods, the rock beds that define the period's start and end are well identified, but the exact dates are uncertain by a few million years. The base of the Silurian is set at a series of major Ordovician–Silurian extinction events when up to 60% of marine genera were wiped out. One important event in this period was the initial establishment of terrestrial life in what is known as the Silurian-Devonian Terrestrial Revolution: vascular plants emerged from more primitive land plants, dikaryan fungi started expanding and diversifying along with glomeromycotan fungi, and three groups of arthropods (myriapods, arachnids and hexapods) became fully terrestrialized. A significant evolutionary milestone during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Syncline
In structural geology, a syncline is a fold with younger layers closer to the center of the structure, whereas an anticline is the inverse of a syncline. A synclinorium (plural synclinoriums or synclinoria) is a large syncline with superimposed smaller folds. Synclines are typically a downward fold (synform), termed a synformal syncline (i.e. a trough), but synclines that point upwards can be found when strata have been overturned and folded (an antiformal syncline). Characteristics On a geologic map, synclines are recognized as a sequence of rock layers, with the youngest at the fold's center or ''hinge'' and with a reverse sequence of the same rock layers on the opposite side of the hinge. If the fold pattern is circular or elongate, the structure is a basin. Folds typically form during crustal deformation as the result of compression that accompanies orogenic mountain building.

Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wales Online
Media Wales Ltd. is a publishing company based in Cardiff, Wales. As of 2009 it was owned by Reach plc (formerly known as the Trinity Mirror Group). It was previously known as the Western Mail & Echo Ltd. History The ''Western Mail'' was founded in 1869 by the 3rd Marquess of Bute as a Conservative newspaper. In 1893, the original building in St. Mary Street was destroyed by fire and a new building was opened also in St Mary Street two years later. In 1928 the Western Mail Ltd amalgamated with David Duncan & Sons, who published the ''South Wales Daily News'' and the ''South Wales Echo'', which was established in 1884. The merged company became Western Mail and Echo Ltd. and because of the merger ''Evening Express'' and ''South Wales Daily'' News closed. In 1960, the newspapers left St Mary Street and moved to Thomson House, Cardiff. On 1 October 2007 Western Mail and Echo Ltd changed its name to Media Wales, and in 2008 Media Wales moved from Thomson House in Havelock Str ...
