Coregonus Vandesius
''Coregonus vandesius'', the vendace , is a freshwater whitefish found in the United Kingdom. Population surveys since the 1960s have revealed a steady decline and the fish is no longer present in some of its previous haunts but is still present in Bassenthwaite Lake and Derwent Water. The main threats it faces are eutrophication and the introduction of alien species of fish which eat its eggs and fry. The International Union for Conservation of Nature has rated its conservation status as "endangered". Taxonomy Most authorities now consider ''Coregonus vandesius'' to be a subjective synonym of ''Coregonus albula'', which is a more widespread North European freshwater whitefish species. Both taxa are also known by the common name vendace. The status however remains controversial, and FishBase still lists ''C. vandesius'' as a separate species, reflecting the recent treatment of the European freshwater fish fauna by Kottelat & Freyhof (2007). Another synonym of British ''C. vandes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Celtic Languages
The Celtic languages (usually , but sometimes ) are a group of related languages descended from Proto-Celtic. They form a branch of the Indo-European language family. The term "Celtic" was first used to describe this language group by Edward Lhuyd in 1707, following Paul-Yves Pezron, who made the explicit link between the Celts described by classical writers and the Welsh and Breton languages. During the 1st millennium BC, Celtic languages were spoken across much of Europe and central Anatolia. Today, they are restricted to the northwestern fringe of Europe and a few diaspora communities. There are six living languages: the four continuously living languages Breton, Irish, Scottish Gaelic and Welsh, and the two revived languages Cornish and Manx. All are minority languages in their respective countries, though there are continuing efforts at revitalisation. Welsh is an official language in Wales and Irish is an official language of Ireland and of the European Union ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ex-situ Conservation
Svalbard GLOBAL SEED BANK, an ''ex situ'' conservation. ''Ex situ'' conservation literally means, "off-site conservation". It is the process of protecting an endangered species, variety or breed, of plant or animal outside its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, an artificial environment which is similar to the natural habitat of the respective animal and within the care of humans, example are zoological parks and wildlife safaris. The degree to which humans control or modify the natural dynamics of the managed population varies widely, and this may include alteration of living environments, reproductive patterns, access to resources, and protection from predation and mortality. ''Ex situ'' management can occur within or outside a species' natural geographic range. Individuals maintained ''ex situ'' exist outside an ecological niche. This means that they are not under the same selection pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dumfries And Galloway
Dumfries and Galloway ( sco, Dumfries an Gallowa; gd, Dùn Phrìs is Gall-Ghaidhealaibh) is one of 32 unitary council areas of Scotland and is located in the western Southern Uplands. It covers the historic counties of Dumfriesshire, Kirkcudbrightshire, and Wigtownshire, the latter two of which are collectively known as Galloway. The administrative centre and largest settlement is the town of Dumfries. The second largest town is Stranraer, on the North Channel coast, some to the west of Dumfries. Following the 1975 reorganisation of local government in Scotland, the three counties were joined to form a single region of Dumfries and Galloway, with four districts within it. The districts were abolished in 1996, since when Dumfries and Galloway has been a unitary local authority. For lieutenancy purposes, the area is divided into three lieutenancy areas called Dumfries, Wigtown and the Stewartry of Kirkcudbright, broadly corresponding to the three historic counties. ...

Algae 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 organi ...

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lochmaben
Lochmaben ( Gaelic: ''Loch Mhabain'') is a small town and civil parish in Scotland, and site of a castle. It lies west of Lockerbie, in Dumfries and Galloway. By the 12th century the Bruce family had become the local landowners and, in the 14th century, Edward I rebuilt Lochmaben Castle. It was subsequently taken by Archibald Douglas, 3rd Earl of Douglas in 1384/5 and was abandoned in the early 17th century. The town itself became a Royal Burgh in 1447. History Etymology It is likely that the name ''Lochmaben'' represents the Roman name ''Locus Maponi''. This name is Brittonic in origin, and contains the element ''luch'', meaning "marshy or brackish water" (Welsh ''llwch'', Gaelic '' loch''), and the name ''Mapon'', a deity name meaning "Great (divine) son or youth". The first part of the name could also be explained as ''log'', an element derived from Latin ''locus'', "a place". Early inhabitants Lochmaben has been inhabited since earliest times, owing to its strategic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake District
The Lake District, also known as the Lakes or Lakeland, is a mountainous region in North West England. A popular holiday destination, it is famous for its lakes, forests, and mountains (or '' fells''), and its associations with William Wordsworth and other Lake Poets and also with Beatrix Potter and John Ruskin. The Lake District National Park was established in 1951 and covers an area of . It was designated a UNESCO World Heritage Site in 2017. The Lake District is today completely within Cumbria, a county and administrative unit created in 1974 by the Local Government Act 1972. However, it was historically divided between three English counties (Cumberland, Westmorland and Lancashire), sometimes referred to as the Lakes Counties. The three counties met at the Three Shire Stone on Wrynose Pass in the southern fells west of Ambleside. All the land in England higher than above sea level lies within the National Park, including Scafell Pike, the highest mountain in E ...

Copepod
Copepods (; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat. Some species are planktonic (inhabiting sea waters), some are benthic (living on the ocean floor), a number of species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, and puddles, damp moss, or water-filled recesses (phytotelmata) of plants such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the adult and then, after more molts, achieves adult development. The nauplius form is so ...
