Rahasane Turlough
Rahasane turlough is a turlough (an intermittent lake), west of Craughwell in southwest County Galway. It is the largest surviving turlough in Ireland. A turlough is a karst lake, which has no surface outlet and is surrounded on all sides by rising land. At Rahasane the drainage has been modified in that since the nineteenth century the Dunkellin river has followed an artificial channel downstream of the turlough, but part of the flow continues to go underground, via a natural sink, into the underlying limestone. Rahasane consists of two basins which are connected at times of flood but separated as the waters decline. It covers 257 ha at an altitude of 10–30m above sea level. The site comprises marshes, and seasonally flooded wet meadows, with limestone outcrops and scrub at its margins. In the summer the lake empties and the basin is grazed by cattle, horses and sheep. The southern basin is the more impressive feature, with high rocky sides above an undulating base, strew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

American Wigeon
The American wigeon (''Mareca americana''), also known as the baldpate, is a species of dabbling duck found in North America. Formerly assigned to ''Anas'', this species is classified with the other wigeons in the dabbling duck genus ''Mareca''. It is the New World counterpart of the Eurasian wigeon. Taxonomy The American wigeon was formally described in 1789 by German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with all the other ducks, geese and swans in the genus ''Anas'' and coined the binomial name ''Anas americana''. Gmelin based his description on Edme-Louis Daubenton's hand-colour plate of "Le Canard Jensen, de la Louisiane" and Thomas Pennant's description of the "American wigeon" in his ''Arctic Zoology''. Pennant had been sent a specimen from New York. The American wigeon is now placed with the Eurasian wigeon and three other dabbling ducks in the genus ''Mareca'' that was introduced in 182 ...

Protected Areas Of County Galway
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Important Bird Areas Of The Republic Of Ireland
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So on this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world actually is and how the world would have bee ...

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...

Lakes Of County Galway
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tanymastix Stagnalis
''Tanymastix stagnalis'' is a species of Anostraca (fairy shrimp) that lives in temporary pools across Europe. It may reach up to in some areas and has 11 pairs of bristly, flattened appendages. It swims upside-down and filters food particles from the water. It is the only species of Anostraca in Ireland, having been discovered in Rahasane turlough in 1974. Description ''Tanymastix stagnalis'' has a pair of stalked eyes, and 11 pairs of thoracic appendages, called ''phyllopodia''. The abdomen bears no appendages except for the caudal furca and the external genitalia. In the male the genitalia are a pair of retractable hemipenes, while the female has a brood pouch with two spines. The antennae are also sexually dimorphic, being prehensile in males. At the end of the abdomen, a caudal furca is made up of two red ''cercopods'', which are long, thin and setose. Reports of the size of ''Tanymastix stagnalis'' vary. In Spain, it is reported to reach lengths of , while Macedonian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
