Lough Leane
Lough Leane (; , a personal name) 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 Although the lake's name has been misinterpreted as meaning the "lake of learning" in reference to the monastery on Innisfallen, an island in the lake that was a centre of scholarship in the early Middle Ages, there is no linguistic evidence to support this belief. The lake takes its name from ''Léan Línfhiaclach'', a character mentioned in the ''dindshenchas'' or place-lore tradition. 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. Geography Lough Leane is approximately in size. It is also the largest body of fresh water in the region. It has become eutrophic as a result of phosphates from agricultural and d ...

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 ...

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), leavin ... [...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 ''Alosidae'', 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 conservation ... [...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 c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critically Endangered
An IUCN Red List critically endangered (CR or sometimes CE) species is one that has been categorized by the International Union for Conservation of Nature as facing an extremely high risk of extinction in the wild. As of December 2023, of the 157,190 species currently on the IUCN Red List, 9,760 of those are listed as critically endangered, with 1,302 being possibly extinct and 67 possibly extinct in the wild. The IUCN Red List provides the public with information regarding the conservation status of animal, fungi, and plant species. It divides various species into seven different categories of conservation that are based on habitat range, population size, habitat, threats, etc. Each category represents a different level of global extinction risk. Species that are considered to be critically endangered are placed within the "Threatened" category. As the IUCN Red List does not consider a species extinct until extensive targeted surveys have been conducted, species that a ...

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, extent of water pollution and condition of drinking water. Water quality has a significant impact on water supply and often determines supply options. Impacts on public health Over time, there has been increasing recognition of the importance of drinking water quality and its impact on public health. This has led to increasing protection and management of water quality.

Drainage Basin
A drainage basin is an area of land in which 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 the drainage divide line. A drainage basin's boundaries are determined by watershed delineation, a common task in environmental engineering and science. In a closed drainage basin, or endorheic basin, rather than flowing to the ocean, water converges toward the ... [...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 fresh water 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 benign effects, such as feeding of higher trophic levels, to more harmful effects like blocking sunlight from reaching ...

Water Pollution
Water pollution (or aquatic pollution) is the contamination of Body of water, water bodies, with a negative impact on their uses. It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from one of four main sources. These are sewage discharges, industrial activities, agricultural activities, and urban runoff including stormwater. Water pollution may affect either surface water or groundwater pollution, groundwater. This form of pollution can lead to many problems. One is the environmental degradation, degradation of aquatic ecosystems. Another is spreading Waterborne diseases, water-borne diseases when people use polluted water for drinking or irrigation. Water pollution also reduces the ecosystem services such as drinking water provided by the Water resources, water resource. Sources of water pollution are either p ...

Phosphate
Phosphates are the naturally occurring form of the element phosphorus. 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, phosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one proton gives the dihydrogen phosphate ion while removal of two protons gives the hydrogen phosphate ion . These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.

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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
