Iranian Shrew
The Iranian shrew (''Crocidura susiana'') is a species of mammal in the family Soricidae. It is endemic to Iran. It is threatened by habitat loss Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby .... References Sources *Insectivore Specialist Group 1996Crocidura susiana Downloaded on 30 July 2007.

Mammal
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with Saur ...

Endemic
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great fo ...

Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introdu ...

Fauna Of Iran
The wildlife of Iran include the fauna and flora of Iran. One of the most famous wildlife of Iran is the critically endangered Asiatic cheetah (''Acinonyx jubatus venaticus''), which today survives only in Iran. History The wildlife of Iran first been partly described by Hamdallah Mustawfi in the 14th century who only referred to animals. In the 18th and 19th centuries, Samuel Gottlieb Gmelin and Édouard Ménétries explored the Caspian Sea area and the Talysh Mountains to document Caspian fauna. Several naturalists followed in the 19th century, including Filippo de Filippi, William Thomas Blanford, and Nikolai Zarudny who documented mammal, bird, reptile, amphibian and fish species. Flora More than one-tenth of the country is forested. The most extensive growths are found on the mountain slopes rising from the Caspian Sea, with stands of oak, ash, elm, cypress, and other valuable trees. On the plateau proper, areas of scrub oak appear on the best-watered mountain slopes, and vi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crocidura
The genus ''Crocidura'' is one of nine genus, genera of the shrew subfamily Crocidurinae. Members of the genus are commonly called white-toothed shrews or musk shrews, although both also apply to all of the species in the subfamily. With over 180 species, ''Crocidura'' contains the most species of any mammal genus. The name ''Crocidura'' means "woolly tail", because the tail of ''Crocidura'' species are covered in short hairs interspersed with longer ones. They are found throughout all tropical and temperate regions of the Old World, from South Africa north to Europe, and east throughout Asia, as far east as the Malay Archipelago. One species, the possibly extinct Christmas Island shrew (''C. trichura''), also inhabited Christmas Island. They likely originated in Africa or Anatolia, Asia Minor during the Miocene, spread to Europe by the early Pliocene, and spread to eastern Asia and the Mediterranean by the Pleistocene.
