The IUCN Red List Of Threatened Species
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 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. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franz Steindachner
Franz Steindachner (11 November 1834 in Vienna – 10 December 1919 in Vienna) was an Austrian Zoology, zoologist, ichthyologist, and herpetologist. He published over 200 papers on fishes and over 50 papers on reptiles and amphibians. Steindachner described hundreds of new species of fish and dozens of new amphibians and reptiles. At least seven species of reptile have been named after him. Work and career Being interested in natural history, Steindachner took up the study of fossil fishes on the recommendation of his friend Eduard Suess (1831–1914). In 1860 he was appointed to the position of director of the fish collection at the Naturhistorisches Museum, a position which had remained vacant since the death of Johann Jakob Heckel (1790–1857). (in German). Steindachner's reputation as an Ichthyology, ichthyologist grew, and in 1868 he was invited by Louis Agassiz (1807–1873) to accept a position at the Museum of Comparative Zoology at Harvard University.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Sakarya River
The Sakarya (Sakara River, tr, Sakarya Irmağı; gr, Σαγγάριος, translit=Sangarios; Latin: ''Sangarius'') is the third longest river in Turkey. It runs through the region known in ancient times as Phrygia. It was considered one of the principal rivers of Asia Minor (Anatolia) in classical antiquity, and is mentioned in the ''Iliad'' and in ''Theogony''. Its name appears in different forms as Sagraphos, Sangaris, or Sagaris. In ''Geographica'', Strabo wrote during classical antiquity that the river had its sources on Mount Adoreus, near the town of Sangia in Phrygia, not far from the border with Galatia, and flowed in a very tortuous course: first in an eastern, then toward the north, next the north-west and finally the north through Bithynia into the Euxine (Black Sea). Part of its course formed the boundary between Phrygia and Bithynia, which in early times was bounded on the east by the river. The Bithynian part of the river was navigable and was celebrated for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lake Beyşehir
Lake Beyşehir ( tr, Beyşehir Gölü; anciently, Carallis or Karallis ( grc, Κάραλλις), or Caralis or Karalis (Κάραλις)) is a large freshwater lake in Isparta and Konya provinces in southwestern Turkey. It is located at around and is the largest freshwater lake in Turkey. It has an area of 650 km² and is 45 km long and 20 km wide. It carries the same name as the principal urban centre of its region, Beyşehir. Anciently, it was considered part of ancient Isauria.

Manavgat River
Manavgat River originates on the eastern slopes of Western Taurus Mountains in Turkey. In ancient times it was called Melas ( grc, Μέλας). At an elevation of 1,350 m, the outflow of several small springs joins together to become the headwaters of the Manavgat. The largest of these springs is called Dumanli, whose name means "place where there is fog", because of the dense mist that forms above the spring. In addition to the springs from the Taurus Mountains, the Manavgat is also fed underground from large lakes to the north of the mountains, on the Anatolian Plateau. Pliny the Elder considered that the river was the boundary between ancient Pamphylia and Cilicia. From there, the river flows south over conglomerated strata for about 90 km, descending through a series of canyons. Finally, it washes over the Manavgat Waterfall and through the coastal plain and into the Mediterranean Sea. There are many caves in the river watershed area, the most interesting being the Altın ...

Endemic Fauna Of Turkey
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
