The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists are produced by countries and organizations, which assess the risk of extinction to species within a political management unit.
The conservation status of a group of organisms indicates whether the group still exists and how likely the group is to become extinct in the near future. Many factors are taken into account when assessing conservation status: not simply the number of individuals remaining, but the overall increase or decrease in the population over time, breeding success rates, and known threats. Various systems of conservation status are in use at international, multi-country, national and local levels, as well as for consumer use such as sustainable seafood advisory lists and certification. The two international systems are by the International Union for Conservation of Nature (IUCN) and The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
A least-concern species is a species that has been categorized by the International Union for Conservation of Nature (IUCN) as evaluated as not being a focus of species conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or conservation dependent.
Telestes turskyi is a species of cyprinid restricted to lake Buško Blato in Bosnia and Herzegovina and Čikola River, a tributary of the Krka in Croatia. This species was thought to be extinct, but was found in May 2002 by J. Freyhof and N. Bogutskaya. Its habitat continues to decline due to water extraction and drought.
Telestes is a genus of cyprinid fish. It was formerly usually included in Leuciscus.
A species that is extinct in the wild (EW) is one that has been categorized by the International Union for Conservation of Nature as known only by living members kept in captivity or as a naturalized population outside its historic range due to massive habitat loss.
Telestes croaticus, the Croatian Pijor, is a species of cyprinid fish.
Telestes fontinalis, the Spring pijor, is a species of ray-finned fish in the family Cyprinidae. It is found only in Croatia. Its natural habitats are intermittent rivers and inland karsts. It is threatened by habitat loss.
Telestes metohiensis is a species of ray-finned fish in the family Cyprinidae. It is found in Bosnia and Herzegovina and Croatia. Its natural habitats are freshwater springs and inland karsts. It is threatened by habitat loss.
Telestes beoticus, or the paskóviza, is a species of freshwater fish in the family Cyprinidae. It is found only in Greece, in the Kifissos and Assopos drainages. Its natural habitats are rivers, intermittent rivers, and freshwater lakes, and is threatened by habitat loss.
Telestes montenigrinus is a species of ray-finned fish in the family Cyprinidae. It is found in Albania and Serbia and Montenegro.
Telestes muticellus is a species of ray-finned fish in the family Cyprinidae. Commonly known as vairone, it is found in France, Italy, and Switzerland.
Telestes pleurobipunctatus is a species of ray-finned fish in the family Cyprinidae. It is found only in Greece. Its natural habitats are rivers and intermittent rivers. It is threatened by habitat loss.
Telestes polylepis is a species of ray-finned fish in the family Cyprinidae. It is a freshwater fish. It is found only in a 100-metre stretch of a Croatian stream. Its natural habitat is rivers. It is threatened by new species of Pike being introduced to its stream as well as habitat loss. People think they may be extinct within the next few years as there are less than 80 left.
Telestes ukliva, the Ukliva dace, is a species of ray-finned fish in the family Cyprinidae. Endemic to the Cetina river in Croatia and reported as extinct in the 1990s, it was rediscovered in 1997. Earlier authors misidentified T. ukliva as the alien Telestes muticellus and erroneously considered T. ukliva to be extinct. Its natural habitat is rivers. It is threatened by habitat loss.
Salmo dentex is a variety of trout, a freshwater fish in the family Salmonidae, found in the western Balkans. Until recently the identity, biological distinctness and species status of the dentex trout were not properly clarified, but genetic data now suggest it is not a monophyletic unit that could be distinguished from other salmonids as a separate species.
Teleste Oyj is an international technology group in broadband, security and information technologies and related services. The company's customer base consists of data communications operators, train manufacturers, public transport operators, and public sector organisations.
The fish fauna of the Neretva river basin in the western Balkans is representative of the Dinaric karst region and characterized by several endemic and endangered species.
Telestes dabar is a species of freshwater fish in the family Cyprinidae. It is found in Vrijeka and Opacica rivers of eastern Herzegovina.
