Inis Meáin
Inishmaan ( ; , the official name, formerly spelled , meaning "middle island") is the middle of the three main Aran Islands in Galway Bay, off the west coast of Ireland. It is part of County Galway in the province of Connacht. Inishmaan has a population of about 184 (census 2022), making it the least populous of the Aran Islands. It is one of the most important strongholds of traditional Irish culture. The island is predominantly Irish-speaking and part of the Gaeltacht, though all inhabitants have knowledge of English. Geology and geography The island is an extension of The Burren. The terrain of the island is composed of limestone pavements with crisscrossing cracks known as "grykes", leaving isolated rocks called "clints". The limestones date from the Visean period (Lower Carboniferous), formed as sediments in a tropical sea about 350 million years ago, and compressed into horizontal strata with fossil corals, crinoids, sea urchins, and ammonites. Glaciation following ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Placenames Database Of Ireland
The Placenames Database of Ireland (), also known as , is a database and archive of place names in Ireland. It was created by Fiontar, Dublin City University in collaboration with the Placenames Branch of the Department of Tourism, Culture, Arts, Gaeltacht, Sport and Media. The website is a public resource primarily aimed at journalists and translators, students and teachers, historians and researchers in genealogy. Placenames Commission and Placenames Branch The Placenames Commission () was established by the Department of Finance in 1946 to advise Ordnance Survey Ireland and the government of what the Irish name of places should be. Although both the 1922 Constitution of the Irish Free State and the current constitution adopted in 1937 recognised Irish as the national language, the law in regard to placenames was carried over from the 19th-century UK statutes which established the Ordnance Survey and Griffith's Valuation, under which only an English-language name had offi ...

Sea Urchin
Sea urchins or urchins () are echinoderms in the class (biology), class Echinoidea. About 950 species live on the seabed, inhabiting all oceans and depth zones from the intertidal zone to deep seas of . They typically have a globular body covered by a spine (zoology), spiny protective test (biology), tests (hard shells), typically from across. Sea urchins move slowly, crawling with their tube feet, and sometimes pushing themselves with their spines. They feed primarily on algae but also eat slow-moving or sessility (motility), sessile animals such as crinoids and sponges. Their predators include sharks, sea otters, starfish, wolf eels, and triggerfish. Like all echinoderms, adult sea urchins have pentagonal symmetry with their Echinoderm#Larval development, pluteus larvae featuring Bilateral symmetry, bilateral (mirror) symmetry; The latter indicates that they belong to the Bilateria, along with chordates, arthropods, annelids and molluscs. Sea urchins are found in every ocea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calamia Tridens
''Calamia tridens'', the Burren Green, is a moth of the family Noctuidae. Description The wingspan is 37–42 mm. The length of the forewings is 17–18 mm. Whitish green, of the o more or less suffused with grey except along costa, showing a pale curved outer band; fringe white; — in ab. ''immaculata'' Stgr. the whole forewing is uniformly green, with no race of a white reniform. and the hindwings of the male are not fuscous; — ab.

Leptidea Sinapis
''Leptidea sinapis,'' or the wood white butterfly of the family Pieridae, is a small white butterfly that is mainly found in England, Ireland, and Northern Europe. The butterfly has white wings with grey or yellow markings near the center or tip of the wing. It flies slowly and low over its shrubbery habitat. Males initiate courtship with females and can mate multiply, while females tend to only mate once in their lifetime. The wood white was added to the UK BAP Priority Species list in 2005 due to a substantial decline in the population, especially in England. This decline has been attributed to changes in woodland regions, including increased shade due to tree planting, and the failure to maintain woodland rides in a satisfactory way for wood whites to oviposit. Conservation efforts are currently striving to understand how to best maintain woodland regions and are examining the effects of climate change, effect of climate change (particularly during the winter months) on egg su ...

Marsh Fritillary
The marsh fritillary (''Euphydryas aurinia'') is a butterfly of the family Nymphalidae. Commonly distributed in the Palearctic region, the marsh fritillary's common name derives from one of its several habitats, marshland. The prolonged larval stage lasts for approximately seven to eight months and includes a period of hibernation over the winter. The larvae are dependent on the host food plant '' Succisa pratensis'' not only for feeding but also for hibernation, because silken webs are formed on the host plant as the gregarious larvae enter hibernation. Females lay eggs in batches on the host plant and are, like other batch-layers, selective about the location of oviposition because offspring survivorship levels for batch-layers are more tied to location selection than they are for single-egg layers. As of 2019 the butterfly's global conservation status is considered of least concern, but it has faced rapid decline and is considered regionally vulnerable or endangered over much o ...

Brown Hairstreak
The brown hairstreak (''Thecla betulae'') is a butterfly in the family Lycaenidae. The range includes most of the Palaearctic. Description The following description of this butterfly was written by Adalbert Seitz in 1909: ''Z. betulae'' L. Black-brown; male with a pale diffuse patch, female with a broad orange band beyond the crossveins. Underside ochreous, with dark-edged white lines. In North and Central Europe und Northern Asia eastward to the Pacific. Tutt name males without the pale diffuse patch beyond the crossveins ab. ''unicolor'', while this patch is nearly white in ab. ''pallida'' Tutt. In ab. ''spinosae'' Gerh. there appear beyond the apex of the cell small orange-spots , which may be paler yellow than the discal spots of the female. The orange discal band of the female is sometimes narrow: ab. ''restricta'' Tutt, and sometimes broad (= ab. ''lata''). females in which the band is pale ochreous instead of orange are ab. ''fisoni'' Wheeler, while the band is separ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pearl-bordered Fritillary
The pearl-bordered fritillary (''Boloria euphrosyne'') is a butterfly of the family Nymphalidae found in Europe and through Russia across the Palearctic to the north of Kazakhstan. Description The adult butterfly is orange with black spots on the upperside of its wing and has a wingspan of 38–46 mm. The underside of the wings have a row of silver-pearly markings along the edge, which give the species its name. The pearl-bordered fritillary is often confused with the small pearl-bordered fritillary, but can be distinguished by the triangle along its pearl border (the small pearl-bordered has black chevrons) as well as the presence of a single silver spot in the middle of a row of yellow spots. The female has darker markings and rounder wings than the male. The caterpillars are black with white or yellow spines along their backs. Like other species of fritillary, the males have special scent glands on their wings so that they can be recognised by females of their own spe ...

Alps
The Alps () are some of the highest and most extensive mountain ranges in Europe, stretching approximately across eight Alpine countries (from west to east): Monaco, France, Switzerland, Italy, Liechtenstein, Germany, Austria and Slovenia. The Alpine arch extends from Nice on the western Mediterranean Sea, Mediterranean to Trieste on the Adriatic Sea, Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrust fault, thrusting and Fold (geology), folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 82 peaks higher than List of Alpine four-thousanders, . The altitude and size of the range affect the climate in Europe; in the mountain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean
The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern Europe, on the south by North Africa, and on the west almost by the Morocco–Spain border. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The sea was an important rout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic
The Arctic (; . ) is the polar regions of Earth, polar region of Earth that surrounds the North Pole, lying within the Arctic Circle. The Arctic region, from the IERS Reference Meridian travelling east, consists of parts of northern Norway (Nordland, Troms, Finnmark, Svalbard and Jan Mayen), northernmost Sweden (Västerbotten, Norrbotten and Lapland (Sweden), Lappland), northern Finland (North Ostrobothnia, Kainuu and Lapland (Finland), Lappi), Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), the United States (Alaska), Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), and northern Iceland (Grímsey and Kolbeinsey), along with the Arctic Ocean and adjacent seas. Land within the Arctic region has seasonally varying cryosphere, snow and ice cover, with predominantly treeless permafrost under the tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karstification
Karst () is a topography formed from the dissolution of soluble carbonate rocks such as limestone and dolomite. It is characterized by features like poljes above and drainage systems with sinkholes and caves underground. There is some evidence that karst may occur in more weathering-resistant rocks such as quartzite given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. In regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
