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] |
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.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyprinidae
Cyprinidae is a family of freshwater fish commonly called the carp or minnow family. It includes the carps, the true minnows, and relatives like the barbs and barbels. Cyprinidae is the largest and most diverse fish family and the largest vertebrate animal family in general with about 3,000 species, of which only 1,270 remain extant, divided into about 370 genera. Cyprinids range from about 12 mm in size to the giant barb (''Catlocarpio siamensis''). By genus and species count, the family makes up more than two-thirds of the ostariophysian order Cypriniformes. The family name is derived from the Greek word ( 'carp'). Biology and ecology Cyprinids are stomachless fish with toothless jaws. Even so, food can be effectively chewed by the gill rakers of the specialized last gill bow. These pharyngeal teeth allow the fish to make chewing motions against a chewing plate formed by a bony process of the skull. The pharyngeal teeth are unique to each species and are used by scient ...

Tigris–Euphrates River System
The Tigris–Euphrates river system is a large river system in Western Asia which discharges into the Persian Gulf. Its principal rivers are the Tigris and Euphrates along with smaller tributaries. From their sources and upper courses in the mountains of eastern Turkey, the rivers descend through valleys and gorges to the uplands of Syria and northern Iraq and then to the alluvial plain of central Iraq. Other tributaries join the Tigris from sources in the Zagros Mountains to the east. The rivers flow in a south-easterly direction through the central plain and combine at Al-Qurnah to form the Shatt al-Arab and discharge into the Persian Gulf. The rivers and their tributaries drain an area of 879,790 km2, including almost the entire area of Iraq as well as portions of Turkey, Syria, Iran, and Kuwait. The region has historical importance as part of the Fertile Crescent region, in which Mesopotamian civilization is believed to have first emerged. Geography The Tigris–Euphra ...

Fish Described In 1843
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most f ...

Fauna Of Iraq
The wildlife of Iraq includes its flora and fauna and their natural habitats. Iraq has multiple biomes which include the mountainous region in north to the wet marshlands along the Euphrates river. The western part of the country comprises mainly desert and some semi-arid regions. As of 2001, seven of Iraq's mammal species and 12 of its bird species are endangered. The endangered species include the northern bald ibis and Persian fallow deer. The Syrian wild ass is extinct, and the Saudi Arabian dorcas gazelle was declared extinct in 2008. Mesopotamian marshes The marshes are home to 40 species of birds, and several species of fish, plus demarcating a range limit for a number of bird species. The marshes were once home to millions of birds and the stopover for millions of migratory birds, including flamingo, pelican and heron as they migrated from Siberia to Africa. At risk are 40% to 60% of the world's marbled teal population that live in the marshes, along with 90% of the world's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
