The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit.
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 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.
The souffia or western vairone is a species of ray-finned fish in the family Cyprinidae. It is found in Austria, Bosnia and Herzegovina, Croatia, Czech Republic, France, Germany, Hungary, Italy, Liechtenstein, Romania, Slovenia, Slovakia, Switzerland and Ukraine.
Telestes ukliva 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.
The pale gray shrew is a species of mammal in the family Soricidae. It is endemic to Pakistan. It is threatened by habitat loss.
Doratogonus is a genus of millipedes in family Spirostreptidae. They are relatively large, at 80–200 millimetres (3–8 in) long, relatively common, and distributed across Southern Africa. Many of the species are listed on the IUCN Red List due to habitat destruction.
The World's 25 Most Endangered Primates is a list of highly endangered primate species selected and published by the International Union for Conservation of Nature (IUCN) Species Survival Commission (SSC) Primate Specialist Group (PSG), the International Primatological Society (IPS), Global Wildlife Conservation (GWC), and Bristol Zoological Society (BZS). The IUCN/SSC PSG worked with Conservation International (CI) to start the list in 2000, but in 2002, during the 19th Congress of the International Primatological Society, primatologists reviewed and debated the list, resulting in the 2002–2004 revision and the endorsement of the IPS. The publication was a joint project between the three conservation organizations until the 2012–2014 list when BZS was added as a publisher. The 2018–2020 list was the first time Conservation International was not among the publishers, replaced instead by GWC. The list has been revised every two years following the biannual Congress of the IPS. Starting with the 2004–2006 report, the title changed to "Primates in Peril: The World's 25 Most Endangered Primates". That same year, the list began to provide information about each species, including their conservation status and the threats they face in the wild. The species text is written in collaboration with experts from the field, with 60 people contributing to the 2006–2008 report and 85 people contributing to the 2008–2010 report. The 2004–2006 and 2006–2008 reports were published in the IUCN/SSC PSG journal Primate Conservation,, since then they have been published as independent publications.
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.
