Lough Leane
Lough Leane (; ) is the largest of the three lakes of Killarney, in County Kerry. The River Laune flows from the lake into the Dingle Bay to the northwest. Etymology and history The lake's name means "lake of learning" probably in reference to the monastery on Innisfallen, an island in the lake. Innisfallen was a centre of scholarship in the early Middle Ages, producing the ''Annals of Innisfallen'' and, according to legend, educating King Brian Boru. Another historic site, the tower house Ross Castle sits on Ross Island in the lake. Ross Island is rich in copper. Archaeological evidence suggests the island has been mined since the time of the Bronze Age Beaker People.J. P. N. Northover, W. O'Brien and S. Stos.

Killarney
Killarney ( ; ga, Cill Airne , meaning 'church of sloes') is a town in County Kerry, southwestern Ireland. The town is on the northeastern shore of Lough Leane, part of Killarney National Park, and is home to St Mary's Cathedral, Ross Castle, Muckross House and Abbey, the Lakes of Killarney, MacGillycuddy's Reeks, Purple Mountain, Mangerton Mountain, Paps Mountain, the Gap of Dunloe and Torc Waterfall. Its natural heritage, history and location on the Ring of Kerry make Killarney a popular tourist destination. Killarney won the Best Kept Town award in 2007, in a cross-border competition jointly organised by the Department of the Environment and the Northern Ireland Amenity Council. In 2011, it was named Ireland's tidiest town and the cleanest town in the country by Irish Business Against Litter.

Ducks On Lough Leane
Duck is the common name for numerous species of waterfowl in the family Anatidae. Ducks are generally smaller and shorter-necked than swans and geese, which are members of the same family. Divided among several subfamilies, they are a form taxon; they do not represent a monophyletic group (the group of all descendants of a single common ancestral species), since swans and geese are not considered ducks. Ducks are mostly aquatic birds, and may be found in both fresh water and sea water. Ducks are sometimes confused with several types of unrelated water birds with similar forms, such as loons or divers, grebes, gallinules and coots. Etymology The word ''duck'' comes from Old English 'diver', a derivative of the verb 'to duck, bend down low as if to get under something, or dive', because of the way many species in the dabbling duck group feed by upending; compare with Dutch and German 'to dive'. This word replaced Old English / 'duck', possibly to avoid confusion with oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eóganacht Locha Léin
__NOTOC__ Eóganacht Locha Léin or Uí Cairpre Luachra were a branch of the ruling Eóganachta of Munster. Their territory was in Iarmuman or West Munster. Luachair (Lúachra) is the old name of a large district on the borders of Co Cork, Kerry and Limerick. Cairbre of Sliobh Luachra was on the Cork-Kerry border; Eóganacht Locha Léin is around the Lakes of Killarney., p. 1. The ancestor of this branch was Cairpre Luachra mac Cuirc, son of Corc mac Luigthig (or Conall Corc mac Lugdach, the founder of Cashel) by Mungfionn daughter of Feredach, King of the Picts of Scotland. Cairpre Luachra was a sixth generation descendant of Éogan Mór, ancestor of the Eoganachta. Cairpre went west over Luachair Deadhaid (Slieveloughra) to found the lands of his dynasty Ruling septs of Eóganacht Locha Léin included Úa Cathail, Úa Flainn, Úa Muircheartaigh or Moriarty, and Úa Cerbaill. By the 12th century the Úa Donnchadha (O'Donoghues, Cenél Laegaire of Eóganacht Raithlind), leaving E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Killarney Shad
The Killarney shad (''Alosa killarnensis''), also called the goureen, is a freshwater fish in the family ''Clupeidae'', endemic to a single lake in Ireland, Lough Leane in County Kerry. Research has shown that it is a landlocked subspecies of the anadromous, twait shad (''Alosa fallax''), arriving in the lake after the Last Glacial Maximum about 10,000 years ago. This fish is at risk from eutrophication and the introduction of alien species of fish to the lake and the International Union for Conservation of Nature has rated it as " critically endangered". Distribution and status Lough Leane in the Killarney National Park, southwestern Ireland, is only the place where this fish lives. It has been listed as critically endangered by the IUCN. Eutrophication and introduction of alien fish species such as common roach ''Rutilus rutilus'' and common bream ''Abramis brama'' are the most probable threats. The shad is also very sensitive to pollution. The adopted method for conservati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salvelinus Obtusus
''Salvelinus obtusus'', commonly called the blunt-nosed Irish charr or blunt-snouted Irish char, is a species of lacustrine char fish in the family Salmonidae, found in the Lakes of Killarney, Ireland. Taxonomy Name The English word "char is thought to derive from Old Irish ''ceara''/''cera'' meaning "loodred," referring to its pink-red underside. This would also connect with its Welsh name ''torgoch'', "red belly." The species name ''obtusus'' is Latin for "blunt." Biology ''Salvelinus obtusus'' is benthopelagic and can grow up to . It is distinguished from other ''Salvelinus'' in Ireland by its obtuse snout, rounded dorsal profile and short lower jaw, which is included in the upper jaw when the mouth is closed. Its body depth is 20–25% of snout length. Range ''Salvelinus obtusus'' is only found in Muckross Lake and Lough Leane, and is threatened by eutrophication. It was formerly found in Lough Tay, Lough Dan, Lough Nalughraman and Lough Acoose, but is now considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Quality
Water quality refers to the chemical, physical, and biological characteristics of water based on the standards of its usage. It is most frequently used by reference to a set of standards against which compliance, generally achieved through treatment of the water, can be assessed. The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extend of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options. Categories The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for potability, industrial/domestic use, or restoration (of an environment/ecosystem, generally for health of human/aquatic life). Human consumption Contaminants that may be in untreated water include microorganisms such as viruses, protozoa and bacteria; inorganic ...

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algal Bloom
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompasses many types of aquatic photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. ''Algal bloom'' commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels to more harmful effects like blocking sunlight from reaching other organ ...

Water Pollution
Water pollution (or aquatic pollution) is the contamination of water bodies, usually as a result of human activities, so that it negatively affects its uses. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants are introduced into these water bodies. Water pollution can be attributed to one of four sources: sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. It can be grouped into surface water pollution (either fresh water pollution or marine pollution) or groundwater pollution. For example, releasing inadequately treated wastewater into natural waters can lead to degradation of these aquatic ecosystems. Water pollution can also lead to water-borne diseases for people using polluted water for drinking, bathing, washing or irrigation. Water pollution reduces the ability of the body of water to provide the ecosystem services (such as drinking water) that ... [...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] |
Eutrophic Lake
The Trophic State Index (TSI) is a classification system designed to rate water bodies based on the amount of biological productivity they sustain. Although the term "trophic index" is commonly applied to lakes, any surface water body may be indexed. The TSI of a water body is rated on a scale from zero to one hundred. Under the TSI scale, water bodies may be defined as: * oligotrophic (TSI 0–40, having the least amount of biological productivity, "good" water quality); * mesotrophic (TSI 40–60, having a moderate level of biological productivity, "fair" water quality); or * eutrophic to hypereutrophic (TSI 60–100, having the highest amount of biological productivity, "poor" water quality). The quantities of nitrogen, phosphorus, and other biologically useful nutrients are the primary determinants of a water body's TSI. Nutrients such as nitrogen and phosphorus tend to be limiting resources in standing water bodies, so increased concentrations tend to result in increased p ...
