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] |

Gastropods Of Asia
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Gyraulus
''Gyraulus'' is a genus of small, mostly air-breathing, freshwater snails, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails. The genus ''Gyraulus'' is known from the Early Cretaceous to the present. Fossils attributed to ''Gyraulus'' sp. have been found in the lakebottom sediments of the Yixian Formation in China, dating to 125 million years ago.Pan, H. and Zhu, X. (2007). "Early Cretaceous non-marine gastropods from the Xiazhuang Formation in North China." ''Cretaceous Research'', 28(2): 215-224. The minute species '' Gyraulus crista'', although technically a pulmonate gastropod, does not use air for respiration, but instead has a mantle cavity which has much water. Distribution The distribution of this genus is Holarctic. Habitat These snail snails live on water plants in freshwater. Shell description Shell of the species within this genus are small, and are mostly almost planispiral in their coiling. Species Species within the genu ...

Aammiq Wetland
The Aammiq Wetland (the name is also sometimes transliterated as "Ammiq"or "Aamiq") is the largest remaining freshwater wetland in Lebanon, a remnant of much more extensive marshes and lakes that once existed in the Bekaa Valley. It has been designated an Important Bird Area in the Middle East (BirdLife International, 1994), is included in the Directory of Wetlands in the Middle East (IUCN, 1995), was declared Ramsar Convention site number 978 in 1999, and most recently (2005) was designated, with Al Shouf Cedar Nature Reserve, a “Biosphere reserve” by UNESCO. Description The swamp lies on one of the most important bird migration routes in the world, and over 250 species of birds have been recorded in the area, including the globally vulnerable greater spotted eagle (''Aquila clanga''), eastern imperial eagle (''Aquila heliaca''), and lesser kestrel (''Falco naumanni''). Records of globally near-threatened bird species at the wetland include great snipe (''Gallinago media' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palustrine
Palustrine wetlands include any inland wetland that contains ocean-derived salts in concentrations of less than 0.5 parts per thousand, and is non-tidal. The word ''palustrine'' comes from the Latin word ''palus'' or marsh. Wetlands within this category include inland marshes and swamps as well as bogs, fens, pocosins, tundra and floodplains. According to the Cowardin classification system Palustrine wetlands can also be considered the area on the side of a river or a lake, as long as they are covered by vegetation such as trees, shrubs, and emergent plants. Classification Palustrine wetlands are one of five systems of wetlands within the Cowardin classification system. This system was created by Lewis Cowardin and others from the United States Fish and Wildlife Service in 1987. The other systems are: * Marine wetlands, exposed to the open ocean * Estuarine wetlands, partially enclosed by land and containing a mix of fresh and salt water * Riverine wetlands, associated wi ...

Lebanon
Lebanon ( , ar, لُبْنَان, translit=lubnān, ), officially the Republic of Lebanon () or the Lebanese Republic, is a country in Western Asia. It is located between Syria to the north and east and Israel to the south, while Cyprus lies to its west across the Mediterranean Sea; its location at the crossroads of the Mediterranean Basin and the Arabian hinterland has contributed to its rich history and shaped a cultural identity of religious diversity. It is part of the Levant region of the Middle East. Lebanon is home to roughly six million people and covers an area of , making it the second smallest country in continental Asia. The official language of the state is Arabic, while French is also formally recognized; the Lebanese dialect of Arabic is used alongside Modern Standard Arabic throughout the country. The earliest evidence of civilization in Lebanon dates back over 7000 years, predating recorded history. Modern-day Lebanon was home to the Phoenicians, a m ...

Aammiq
Aammiq is a village in the Western Beqaa District in Lebanon. It is also the name of an archaeological site. Archaeology Aamiq or Aammiq II is an archaeological site southwest of Zahle in the Aammiq Wetland, Beqaa Valley, Lebanon. It was first excavated by Jacques Cauvin in 1963, then again by M. Cavalier in 1964, 1965 by Lorraine Copeland and Peter Wescombe and Jacques Besançon & Francis Hours in 1971. Two periods of inhabitation were found, the first period between 12000 and 10200 cal. BC was Natufian or perhaps preceramic neolithic where a skeleton was found covered with red ochre. Tools with agricultural purpose included mortars, grinders and stoneware basalt pestles. Other brown flint lithics recovered include a triangle, blades, scrapers and picks, tools suggested pre-natufian occupation. A late neolithic period was also detected at around 5000-4500 cal BC ( Ubaid period) similar to late neolithic Byblos. Ceramics found included some Chalcolithic sherds and lithics ...

Freshwater Snail
Freshwater snails are gastropod mollusks which live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a shell, with very few exceptions. Some groups of snails that live in freshwater respire using gills, whereas other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are filter feeders. According to a 2008 review of the taxonomy, there are about 4,000 species of freshwater gastropods (3,795–3,972). At least 33–38 independent lineages of gastropods have successfully colonized freshwater environments. It is not possible to quantify the exact number of these lineages yet, because they have yet to be clarified within the Cerit ...

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] |
Sheep
Sheep or domestic sheep (''Ovis aries'') are domesticated, ruminant mammals typically kept as livestock. Although the term ''sheep'' can apply to other species in the genus ''Ovis'', in everyday usage it almost always refers to domesticated sheep. Like all ruminants, sheep are members of the order Artiodactyla, the even-toed ungulates. Numbering a little over one billion, domestic sheep are also the most numerous species of sheep. An adult female is referred to as a ''ewe'' (), an intact male as a ''ram'', occasionally a ''tup'', a castrated male as a ''wether'', and a young sheep as a ''lamb''. Sheep are most likely descended from the wild mouflon of Europe and Asia, with Iran being a geographic envelope of the domestication center. One of the earliest animals to be domesticated for agricultural purposes, sheep are raised for fleeces, meat (lamb, hogget or mutton) and milk. A sheep's wool is the most widely used animal fiber, and is usually harvested by shearing. In Commonw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
