Cyprinion Kais
''Cyprinion kais'', the Kais kingfish or smallmouth lotak, is a species of ray-finned fish in the genus '' Cyprinion''. It is found in the drainage basins of the rivers Tigris and Euphrates, and was also found in the Queiq system but it appears to have been extirpated Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinct ... from that basin following the drying up of that river. Its range covers Turkey, Syria, Iraq and Iran. Its preferred habitat is flowing water in larger warm streams and rivers from where it migrates to canals and probably to other artificial water bodies to forage.

Johann Jakob Heckel
Johann Jakob Heckel (23 January 1790 – 1 March 1857) was an Austrian taxidermist, zoologist, and ichthyologist from Mannheim in the Electoral Palatinate. Life Though not a formally trained biologist, he worked his way up through the ranks to eventually become the director of the Fish Collection at the Naturhistorisches Museum in Vienna. For the most part, he was not a traveler or explorer like many of the scientists of the time, he remained in Vienna, where he studied and catalogued specimens sent to him from the field. Among those who brought specimens to him were Karl Alexander Hügel, Joseph Russegger and Theodor Kotschy — involving collection activities in Kashmir, the Middle East and northeastern Africa that greatly enriched the Vienna museum. Fish were his specialty and he worked with many of the greatest ichthyologists of his time including Cuvier, Valenciennes, Bonaparte, Müller, and Troschel.

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 Actino ...

Tigris
The Tigris () is the easternmost of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of the Armenian Highlands through the Syrian and Arabian Deserts, and empties into the Persian Gulf. Geography The Tigris is 1,750 km (1,090 mi) long, rising in the Taurus Mountains of eastern Turkey about 25 km (16 mi) southeast of the city of Elazığ and about 30 km (20 mi) from the headwaters of the Euphrates. The river then flows for 400 km (250 mi) through Southeastern Turkey before becoming part of the Syria-Turkey border. This stretch of 44 km (27 mi) is the only part of the river that is located in Syria. Some of its affluences are Garzan, Anbarçayi, Batman, and the Great and the Little Zab. Close to its confluence with the Euphrates, the Tigris splits into several channels. First, the artificial Shatt al-Hayy branches off, to join the Euphrates near Nasiriya ...

Euphrates
The Euphrates () is the longest and one of the most historically important rivers of Western Asia. Together with the Tigris, it is one of the two defining rivers of Mesopotamia ( ''the land between the rivers''). Originating in Turkey, the Euphrates flows through Syria and Iraq to join the Tigris in the Shatt al-Arab, which empties into the Persian Gulf. Etymology The Ancient Greek form ''Euphrátēs'' ( grc, Εὐφράτης, as if from Greek εὖ "good" and φράζω "I announce or declare") was adapted from Old Persian 𐎢𐎳𐎼𐎠𐎬𐎢 ''Ufrātu'', itself from Elamite 𒌑𒅁𒊏𒌅𒅖 ''ú-ip-ra-tu-iš''. The Elamite name is ultimately derived from a name spelt in cuneiform as 𒌓𒄒𒉣 , which read as Sumerian is "Buranuna" and read as Akkadian is "Purattu"; many cuneiform signs have a Sumerian pronunciation and an Akkadian pronunciation, taken from a Sumerian word and an Akkadian word that mean the same. In Akkadian the river was called ''Puratt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Queiq River
The Queiq (Modern Standard Arabic: , ''Quwayq'', ; northern Syrian Arabic: ''ʾWēʾ'', ), with many variant spellings, known in antiquity as the Belus ( grc-gre, Βήλος, ''Bēlos''), Chalos and also known in English as the Aleppo River is a river and valley of the Aleppo Governorate, Syria and Turkey. It is a -long river that flows through the northern Syrian city of Aleppo. It arises from the southern Aintab plateau in southeastern Turkey. The Akpınar River in the Kilis plain is one of the headwaters of the Queiq. The former town of Qinnasrin lay on its banks. It partly flows along the western rim of the Matah Depression. The valley has been occupied for thousands of years and in ancient times the Queiq valley was noted for its flint industries and pottery. The river dried up completely in the late 1960s, due to irrigation projects on the Turkish side of the border Borders are usually defined as geographical boundaries, imposed either by features such as o ...

Local Extinction
Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a change in the ecology of an area. In recent times, local extinction has sometimes been followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this. The term "local extinction" is highly vernacular. The more proper biological term is ''extirpation''. Discussion Glaciation can lead to local extinction. This was the case during the Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extirpated from islands over time. The num ...
