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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to ...

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] |
Hydroelectricity
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Ceyhan River
The Ceyhan River (historically Pyramos or Pyramus ( el, Πύραμος), Leucosyrus ( el, Λευκόσυρος) or Jihun) is a river in Anatolia in the south of Turkey. Course of the river The Ceyhan River (Pyramus) has its source (known as ''Söğütlü Dere'') at a location called ''Pınarbaşı'' on the Nurhak Mountains of the Eastern Taurus Mountains range, southeast of the town of Elbistan in the Kahramanmaraş province of Turkey. According to classical references its source is at Cataonia near the town of Arabissus. Its main tributaries are called Harman, Göksun, Mağara Gözü, Fırnız, Tekir, Körsulu, Aksu (which joins Ceyhan at the outskirts of Kahramanmaraş), Çakur, Susas, and Çeperce. Its total length is . In classical times for a time it passed under ground, but then came forward again as a navigable river, and forced its way through a glen of Mount Taurus, which in some parts was so narrow that Strabo claims a dog or hare could leap across it. Its cours ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aksu River (Turkey)
The Aksu (Bronze Age name in Hittite: 𒁉𒋻𒀀𒅀, ''Kaštaraya'', ancient name in Greek Κέστρoς, ''Kestros''), is a river in Antalya Province (southwestern Turkey), which rises in the mountains of Toros. The course of the Aksu is between the Düden to the west and of the Köprüçay to the east. History A treaty between the Hittite Great King Tudhaliya IV and his vassal, the king of Tarhuntassa, defined the latter's western border at the "Kastaraya River", near "Parha". Parha is likely the future Perga. As Kestros, the river is mentioned by Pomponius Mela as navigable, as far upriver as Perga, 60 stadia (about ) from its mouth, according to Strabo. It silted up over the Byzantine era, and Perga declined as a result. Today The Aksu is wide at its mouth, and deep within the bar, which extends across the mouth, and so shallow in places in its delta as to be impassable to boats that draw more than of water.

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 Alt� ...

Manavgat Waterfall By Tomgensler
Manavgat is a city in the district of the Antalya Province in Turkey, from the city of Antalya. The Manavgat River has a waterfall near the city. The population of the district is 242,490 (2020 census). Geography Between the Taurus Mountains to the north, and the sandy beaches of the Mediterranean coast, much of the district is surrounded by a flat plain. This is mostly fertile farmland and agriculture is well-developed in Manavgat, keeping livestock and growing crops including grains, sesame and many fruits and vegetables; in recent years olives have also been planted. There is no industry except for food-processing, so apart from agriculture the local economy depends on tourism. The mountains are covered with forests and typical Mediterranean shrubs, there are small plains higher in the mountains too, traditionally used for summer grazing by the yörük nomads. Manavgat has a Mediterranean climate of hot, dry summers and warm, wet winters; the temperature rarely drops ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebra
The spinal column, a defining synapomorphy shared by nearly all vertebrates, Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the backbone), and on the other with phylogenetic differences among the vertebrate taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans ( whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against r ...
