Boho Caves
The Boho Caves (pronounced , ) are a collection of caves centred on the village of Boho, County Fermanagh on the northern slopes of Belmore Mountain. They encompass the main Boho Cave and the smaller Waterfall Cave and Upper and Lower Ravine Caves. The Boho Cave system is the sixth-longest cave system in Northern Ireland, is designated an Area of Special Scientific Interest (ASSI #144) and is the only example of joint-controlled caves in Northern Ireland. Geology and hydrology The rock strata at Boho Caves date from the Asbian substage of the Carboniferous period, estimated to be around 325 million years old. The rock sequence exposed at Boho consists of the Glencar Limestone Formation which is overlain by the Dartry Limestone Formation, composed of cherty limestones and limestones and shales of the Carn Limestone Member. The Dartry Limestone is, in turn, overlain by the Meenymore Formation and the Glenade Sandstone. The caves are formed within the Dartry Limestone. T ...

Irish Grid Reference System
The Irish grid reference system is a system of geographic grid references used for paper mapping in Ireland (both Northern Ireland and the Republic of Ireland). The Irish grid partially overlaps the British grid, and uses a similar co-ordinate system but with a meridian more suited to its westerly location. Usage In general, neither Ireland nor Great Britain uses latitude or longitude in describing internal geographic locations. Instead grid reference systems are used for mapping. The national grid referencing system was devised by the Ordnance Survey, and is heavily used in their survey data, and in maps (whether published by the Ordnance Survey of Ireland, the Ordnance Survey of Northern Ireland or commercial map producers) based on those surveys. Additionally grid references are commonly quoted in other publications and data sources, such as guide books or government planning documents. 2001 recasting: the ITM grid In 2001, the Ordnance Survey of Ireland and the Ordnance Su ...

Flowstone
Flowstones are sheetlike deposits of calcite or other carbonate minerals, formed where water flows down the walls or along the floors of a cave. They are typically found in "solution caves", in limestone, where they are the most common speleothem. However, they may form in any type of cave where water enters that has picked up dissolved minerals. Flowstones are formed via the degassing of vadose percolation waters. Flowstone may also form on manmade structures as a result of calcium hydroxide being leached from concrete, lime or mortar. These secondary deposits created outside the cave environment, which mimic the shapes and forms of speleothems, are classified as "calthemites" and are associated with concrete degradation.Smith, G.K., (2016). “Calcite Straw Stalactites Growing From Concrete Structures”, Cave and Karst Science, Vol.43, No.1, P.4-10, (April 2016), British Cave Research Association, ISSN 1356-191X.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Metellina Merianae
''Metellina merianae'' is a spider species found in Europe Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia ... up to Georgia. They most commonly dwell in the entrances of caves but can also be found in burrows and hollow trees. Web structure is specific to each species. The webs of ''M. merianae'' reach up to about 100 squared cm. Hesselberg, T., & Simonsen, D. (2019).

Meta Menardi
''Meta menardi'', the European cave spider, is a long-jawed orb-weaving spider (family Tetragnathidae). It is also known as the orbweaving cave spider, the cave orbweaver and, in context, simply the cave spider. Habitat They have a natural range extending from Scandinavia to North Africa and from Europe to Korea; there are also transplanted populations as far apart as Japan and Madagascar. The adult spiders are photophobic and live in places free from light, frequently in caves and tunnels, though they can sometimes be seen outside of caves and mines as they will emerge around dusk to hunt, often using a single silk lasso line and swinging down upon their prey. They are often found in areas that are frequented by bats. The spiders are most often observed in railway tunnels and mines since these are more likely to be visited by humans. The young spiders are, after several instars (and in contrast to the adults), strongly attracted to light—probably an evolutionary adaptati ...

National Museum Of Ireland
The National Museum of Ireland ( ga, Ard-Mhúsaem na hÉireann) is Ireland's leading museum institution, with a strong emphasis on national and some international archaeology, Irish history, Irish art, culture, and natural history. It has three branches in Dublin, the archaeology and natural history museums adjacent on Kildare Street and Merrion Square, and a newer Decorative Arts and History branch at the former Collins Barracks, and the Country Life museum in County Mayo. History Predecessors The National Museum of Ireland descends from the amalgamation of parts of the collections of a number of Dublin cultural institutions from the 18th and 19th centuries, including primarily the Royal Dublin Society (RDS) and the Royal Irish Academy (RIA). The earliest parts of the collections are largely geological and mineralogical specimens, which the RDS collected as a means to improve the knowledge and use of such resources in Ireland. The establishment of the museum collections ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daubenton's Bat
Daubenton's bat or Daubenton's myotis (''Myotis daubentonii'') is a Eurasian bat with rather short ears. It ranges from Ireland to Japan (Hokkaido) and is considered to be increasing its numbers in many areas. This bat was first described in 1817 by Heinrich Kuhl, who named it in honour of French naturalist Louis-Jean-Marie Daubenton. Description Daubenton's bat is a medium-sized to small species. The bat's fluffy fur is brownish-grey on the back and silvery-grey on the underside. Juveniles have darker fur than adults. The bats have reddish-pink faces and noses, but the area around the eyes is bare. When the bat is agitated, the ears are held at right angles. The wings and tail membrane are dark brown. Daubenton's bat is typically 45 to 55 mm long, with an average wingspan of 240 to 275 mm, and weighs between 7 and 15 g. Lifespan Daubenton's bats can live for up to 22 years. Habitat Daubenton's bat is found throughout Ireland and Europe, and as far as Japan and Kor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cave Survey
A cave survey is a map of all or part of a cave system, which may be produced to meet differing standards of accuracy depending on the cave conditions and equipment available underground. Cave surveying and cartography, i.e. the creation of an accurate, detailed map, is one of the most common technical activities undertaken within a cave and is a fundamental part of speleology. Surveys can be used to compare caves to each other by length, depth and volume, may reveal clues on speleogenesis, provide a spatial reference for other areas of scientific study and assist visitors with route-finding. Traditionally, cave surveys are produced in two-dimensional form due to the confines of print, but given the three-dimensional environment inside a cave, modern techniques using computer aided design are increasingly used to allow a more realistic representation of a cave system. History The first known plan of a cave dates from 1546, and was of a man-made cavern in tufa called the Stufe di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yorkshire Ramblers' Club
The Yorkshire Ramblers' Club (YRC) is the second-oldest mountaineering club in England, the oldest being the Alpine Club. Founded in 1892, the YRC is still a highly active club mountaineering and caving in the UK and all over the world. History On 13 July 1892 four Yorkshire gentlemen met at the home of a Mr. Herbert Slater in Leeds to discuss the idea of forming a club for individuals interested in promoting the idea of walking and the study of the countryside. At an open meeting held at the Skyrack Inn, Headingley on 6 October 1892 it was unanimously decided to form a club to organise walking and mountaineering expeditions and encourage the study of nature. The name of the club was picked from others including The Three Peaks Club, but Yorkshire understatement prevailed and the name Yorkshire Ramblers' Club was chosen. Consequently, "greater attention was paid to climbing the Lake District", in both the club's earliest days and today with the adjoining Scottish Borde ...

Lyster Jameson
Henry Paul William Lyster Jameson (1875, Louth – 26 February 1922, West Mersea) was a zoologist, who studied pearl-formation. He also made contributions to speleology and encouraged the study of psychology in adult education. Life H. Lyster Jameson was born in Louth the son of Paul Lyster Jameson, the rector of Killincoole. He was educated at Trinity College Dublin. In 1895 he explored the Marble Arch Caves with Édouard-Alfred Martel, and was the first to describe fauna in the Mitchelstown Cave. After a year at the Royal College of Science in London, Jameson studied zoology under Otto Bütschli at the University of Heidelberg, writing his dissertation (1898) on , a species of spoon worms. Put in charge of a pearling station in British New Guinea, he studied the causes of pearl-formation. He continued this research at the Lancashire Sea Fisheries Station in Piel Island, Barrow-in-Furness, developing the parasitic theory of pearl-formation in the common sea mussel. After devel ...
