Gunung Sewu (Thousand mountains) is the name for the karst region of southern central Java that lies to the south east of Yogyakarta , south of Surakarta , and is considered a very dry and poor socio-economical region in Java. It has poor rainfall compared to the volcanic mountain areas to the north and east. Administratively most of the region is part of Gunung Kidul Regency , within the Yogyakarta province besides Wonogiri Regency and Pacitan Regency . In 1993, the world speleologs proposed Sewu Mountains Karst Area as a world heritage. And on December 6, 2004 Sewu Mountains and South Gombong have been announced as eco-karst.
4-670: It is a region where archaeological evidence shows very early human activity It is very popular with cavers. There are 119 caves below of about 40,000 karst cone hills in 13,000 square kilometer area. The only cave-adapted crab from Java, Sesarmoides jacobsoni ( Sesarmidae ), is endemic to the Gunung Sewu cave system. On September 19, 2015 UNESCO announced Gunung Sewu area as Global Geopark Network follows Mount Batur area. Gunung Sewu area lays 85 kilometers in 3 provinces, Yogyakarta Province, Central Java Province and East Java Province . The longest cave found at Gunung Sewu area
8-429: A result, many troglobiotic species are endemic to a single cave or system of caves. Not all cave dwelling species are considered to be troglobites. An animal found in an underground environment may be a troglophile (a species living both in subterranean and in epigean habitats, e.g. bats and cave swallows ) or a trogloxene (a species only occurring sporadically in a hypogean habitat and unable to establish
12-700: Is 25 kilometers Luweng Jaran and the deepest is 200 meters Luweng Ngepoh. This Yogyakarta location article is a stub . You can help Misplaced Pages by expanding it . Troglobite A troglobite (or, formally, troglobiont ) is an animal species , or population of a species, strictly bound to underground habitats, such as caves. These are separate from species that mainly live in above-ground habitats but are also able to live underground (eutroglophiles), and species that are only cave visitors ( subtroglophiles and trogloxenes ). Land-dwelling troglobites may be referred to as troglofauna , while aquatic species may be called stygofauna , although for these animals
16-736: The term stygobite is preferable. Troglobites typically have evolutionary adaptations to cave life. Examples of such adaptations include slow metabolism , reduced energy consumption, better food usage efficiency, decrease or loss of eyesight ( anophthalmia ), and depigmentation (absence of pigment in the integument ). Conversely, as opposed to lost or reduced functions, many species have evolved elongated antenna and locomotory appendages , in order to better move around and respond to environmental stimuli . These structures are also full of chemical , tactile , and humidity receptors . Troglobites commonly do not survive well outside caves and therefore cannot travel between separate cave systems. As
