Myxas Glutinosa
''Myxas glutinosa'' (glutinous snail) is a species of small air-breathing freshwater snail, an aquatic gastropod mollusc in the family Lymnaeidae, the pond snails. Anatomy This snail is unusual in that it extends its almost transparent mantle to completely cover the shell when it is in motion, giving the very small animal a glass-like appearance. It also makes the animal sticky to the touch, hence its common name. Shell Description The shell is 13 to 16 mm in height and 11 mm to 15 mm in width in the adult. The upper whorls are almost flat so that the shell has a short blunt spire, the last whorl is inflated and predominating. The aperture is more than 90% of the shell height. The umbilicus is closed. The shell colour is brown or green, extremely thin and very transparent and shiny. Distribution This species is European: it is now rare in western Europe, and even rarer in eastern Europe. * British Isles - listed in List of endangered species in the British I ...

Gastropod Shell
The gastropod shell is part of the body of many gastropods, including snails, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, ostracum, is typically made of calcium carbonate (CaCO3) precipitated into an organic matrix ...

Royal Canal (Ireland)
The Royal Canal () is a canal originally built for freight and passenger transportation from Dublin to Longford in Ireland. It is one of two canals from Dublin to the River Shannon and was built in direct competition to the Grand Canal. The canal fell into disrepair in the late twentieth century, but much of it has since been restored for navigation. The length of the canal to the River Shannon was reopened on 1 October 2010, but a final spur branch, to Longford Town, remains closed. History Construction In 1755, Thomas Williams and John Cooley made a survey to find a suitable route for a man-made waterway across north Leinster from Dublin to the Shannon. They originally planned to use a series of rivers and lakes, including the Boyne, Blackwater, Deel, Yellow, Camlin and Inny and Lough Derravaragh. A disgruntled director of the Grand Canal Company sought support to build a canal from Dublin to Cloondara, on the Shannon in West County Longford. Work on this massive pro ...

Animalbase
AnimalBase is a project brought to life in 2004 and is maintained by the University of Göttingen, Germany. The goal of the AnimalBase project is to digitize early zoological literature, provide copyright-free open access to zoological works, and provide manually verified lists of names of zoological genera and species as a free resource for the public. AnimalBase contributed to opening up the classical taxonomic literature, which is considered as useful because access to early literature (especially for the late 18th century) can be difficult for researchers who need the old sources for their taxonomic research. AnimalBase data are public domain. The public use of AnimalBase data is not restricted or conditioned.AnimalBase Project Group, 2005-2010. AnimalBase. Early zoological literature online. World wide web electronic publication http://www.animalbase.uni-goettingen.de accessed 30 July 2010. AnimalBase covers all zoological disciplines. In the field of biodiversity informatics ...

Robert Welch (photographer)
Robert John Welch (22 July 1859 – 28 September 1936) was an Irish photographer interested in natural history, particularly mollusca. Welch, born in Strabane, County Tyrone, lived for a time in Enniskillen. He was the son of an accomplished Scottish amateur photographer. After the death of his father, Welch established his own business in 1883 in Lonsdale Street in Belfast. Much of his time was spent taking pictures that reflected the life of the people and the contemporary landscape. Career Welch specialised in outdoors photography and took thousands of photographs of the towns and scenery of Ireland. He was a craftsman and his studies of Ireland and Irish life in the late 19th and early 20th centuries are viewed as a valuable resource. Welch also took many important photographs of national monuments, megaliths and dolmens, particularly of sites such as Carrowmore, Loughcrew, the Hill of Tara and Newgrange. Welch is considered to have an excellent sense of composition oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Journal Of Limnology
The ''Journal of Limnology'' is a triannual peer-reviewed open access scientific journal covering all aspects of limnology, including the ecology, biology, microbiology, geology, physics, and chemistry of freshwater habitats, as well as the impact of human activities and the management and conservation of inland aquatic ecosystems.

Irish Naturalist
''The Irish Naturalist'' was a scientific journal that was published in Dublin, Ireland, from April 1892 until December 1924. History The journal owed its establishment to the efforts of several leading Dublin naturalists, notably George H. Carpenter and R. M. Barrington. The first editors were Carpenter and Robert Lloyd Praeger, of the National Library of Ireland. The journal was supported by a number of societies, including the Royal Zoological Society of Ireland, the Dublin Microscopical Club, the Belfast Naturalists' Field Club, and the Dublin Naturalists' Field Club. ''The Irish Naturalist'' was published for 33 years and contained in total over 3000 pages. The journal ceased publication in December 1924. It had been having some financial problems, but the final blow came when Carpenter took up his appointment to the keepership of the Manchester Museum in 1923. The journal was succeeded in 1925 by the ''Irish Naturalists' Journal''. Contributors Among notable con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
