Velebit Caves
The Velebit mountains of Croatia have several deep caves with some of the world's largest subterranean vertical drops. The "Lukina jama" cave is 1431 m deep (2013), the deepest cave in Croatia, 14th deepest cave in the world and the deepest cave in southeast Europe.Radovan Radovinovič, The Croatian Adriatic Tourist Guide, pg. 143, Zagreb (1999), At its foot, there are ponds and streams including one of the largest known colonies of subterranean leeches (''Erpobdella mestrovi''), which has been ascertained to represent a new species, genus and also family. Other species discovered in the system, include the air-breathing land snails ''Zospeum tholussum''. Like Lukina jama, Slovacka jama, Velebita and Meduza are also located at the " Hajdučki i Rožanski kukovi" special reserve, a dedicated part of the Sjeverni Velebit national park A national park is a nature park, natural park in use for conservation (ethic), conservation purposes, created and protected by national governm ...

Rožanski Kukovi
The Northern Velebit National Park ( hr, Nacionalni park Sjeverni Velebit) is a national park in Croatia that covers 109 km2 of the northern section of the Velebit mountains, the largest mountain range in Croatia. Because of the abundant variety of this part of the Velebit range, the area was upgraded from a nature reserve in 1999, and opened as a national park in September the same year. The whole of the Velebit range is a "nature park", a lesser conservation category. Another national park on Velebit is the Paklenica on its southern side. In 2017, the beech forests within the national park were added to the UNESCO World Heritage Site known as Ancient and Primeval Beech Forests of the Carpathians and Other Regions of Europe because of their testimony to the ecological history of forest dynamics within Europe since the last Ice Age. The park The park reserve is protected and visitors are restricted to designated trails. Inside the reserve is the ''Visibaba'' (Galanthus) b ...

Limestone Caves
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limestone co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caves Of Croatia
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...

Pitch (vertical Space)
In rock climbing and ice climbing, a pitch is a steep section of a route that requires a rope between two belays, as part of a climbing system. Standard climbing ropes are between 50 and 80 metres long, so a pitch is always shorter, between two convenient ledges if possible; longer routes are multi-pitch, requiring the re-use of the rope each time. In free climbing, pitch refers to classification by climbers of the difficulty of ascent on certain climbing routes. illustrated superimposed on the successful ascent of the Dawn Wall, as photographed on El Capitan in Yosemite. In climbing In advanced climbing or mountaineering, another definition of ''pitch'' is not restricted by the length of the rope.

Slovakia
Slovakia (; sk, Slovensko ), officially the Slovak Republic ( sk, Slovenská republika, links=no ), is a landlocked country in Central Europe. It is bordered by Poland to the north, Ukraine to the east, Hungary to the south, Austria to the southwest, and the Czech Republic to the northwest. Slovakia's mostly mountainous territory spans about , with a population of over 5.4 million. The capital and largest city is Bratislava, while the second largest city is Košice. The Slavs arrived in the territory of present-day Slovakia in the fifth and sixth centuries. In the seventh century, they played a significant role in the creation of Samo's Empire. In the ninth century, they established the Principality of Nitra, which was later conquered by the Principality of Moravia to establish Great Moravia. In the 10th century, after the dissolution of Great Moravia, the territory was integrated into the Principality of Hungary, which then became the Kingdom of Hungary in 1000. In 1241 a ...

National Park
A national park is a nature park, natural park in use for conservation (ethic), conservation purposes, created and protected by national governments. Often it is a reserve of natural, semi-natural, or developed land that a sovereign state declares or owns. Although individual nations designate their own national parks differently, there is a common idea: the conservation of 'wild nature' for posterity and as a symbol of national pride. The United States established the first "public park or pleasuring-ground for the benefit and enjoyment of the people", Yellowstone National Park, in 1872. Although Yellowstone was not officially termed a "national park" in its establishing law, it was always termed such in practice and is widely held to be the first and oldest national park in the world. However, the Tobago Main Ridge Forest Reserve (in what is now Trinidad and Tobago; established in 1776), and the area surrounding Bogd Khan Mountain, Bogd Khan Uul Mountain (Mongolia, 1778), wh ...

Velebit
Velebit (; it, Alpi Bebie) is the largest, though not the highest, mountain range in Croatia. The range forms a part of the Dinaric Alps and is located along the Adriatic coast, separating it from Lika in the interior. Velebit begins in the northwest near Senj with the Vratnik mountain pass and ends 145 km to the southeast near the source of the Zrmanja river northwest of Knin. Its highest peak is the Vaganski vrh at 1,757 m. Major mountain passes on Velebit include the aforementioned Vratnik or Senjsko bilo at 694 m.a.s.l., where the ''Josephina (road), Josephina'' connects Senj with Josipdol; Oštarijska vrata at 928 m.a.s.l. that connects Karlobag and Gospić; and Prezid at 766 m.a.s.l. that connects Obrovac, Croatia, Obrovac and Gračac. The important characteristic of Velebit is its simple, solid form, stiff cliffs, and the nakedness of seaward side (towards the Velebit Channel) and the wood-covered slopes of the Lika side. The basic geological characteristic of the m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zospeum Tholussum
''Zospeum tholussum'' or the domed land snail, is a cave-dwelling species of air-breathing land snails in the family Ellobiidae. It is a very small species, with a shell height of less than and a shell width of around . ''Z. tholussum'' individuals are completely blind and possess translucent shells with five to six whorls. The second whorl of their shells has a characteristic dome-like shape. They are also extremely slow-moving and may depend on passive transportation through running water or larger animals for dispersal. ''Zospeum tholussum'' was discovered at depths of in the Lukina jama–Trojama cave system in Croatia in 2012, during a caving expedition. It was formally described as a new species in 2013 by the taxonomist Dr. Alexander M. Weigand. On 22 May 2014 International Institute for Species Exploration declared the snail as one of the "Top 10 New Species of 2014" among species discovered in 2013. The reason for its selection is its habitat in complete darkness of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erpobdella Mestrovi
''Erpobdella mestrovi'' is a species of troglobitic leech found only in deep caves in Northern Velebit, part of the Dinaric Alps of Croatia. The leech was first found in Lukina jama in 1994, which at 1431 meters deep is the deepest cave in Croatia. The leech has been found in several other caves systems in Velebit such as Slovacka jama (-1320 m), Olimp (-531 m) and Velebita (-1026 m), and is currently considered endemic to Croatia. This leech inhabits underground streams and has several adaptations to deal with a rheophilic and troglobitic A troglobite (or, formally, troglobiont) is an animal species, or population of a species, strictly bound to underground habitats, such as caves.
