Cobitis Arachthosensis
''Cobitis arachthosensis'' is a species of ray-finned fish in the true loach family (Cobitidae). It is endemic to Greece. It belongs to the subgenus ''Bicanestrinia'', together with '' C. hellenica'', '' C. meridionalis'', and '' C. trichonica''. According to cladistic analysis of DNA sequence data (nDNA RAG-1 and S7 ribosomal protein intron 1, and mtDNA cytochrome ''b''), the first of these is an extremely close relative and the present species might arguably be included in it. ''C. hellenica'' occurs in the Louros and Thiamis River basins, parapatric to the range of ''C. arachthosensis''.Perdices, Anabel; Bohlen, Jörg & Doadrio, Ignacio (2008): The molecular diversity of adriatic spined loaches (Teleostei, Cobitidae).

Ribosomal Protein
A ribosomal protein (r-protein or rProtein) is any of the proteins that, in conjunction with rRNA, make up the ribosomal subunits involved in the cellular process of translation. ''E. coli'', other bacteria and Archaea have a 30S small subunit and a 50S large subunit, whereas humans and yeasts have a 40S small subunit and a 60S large subunit. Equivalent subunits are frequently numbered differently between bacteria, Archaea, yeasts and humans. A large part of the knowledge about these organic molecules has come from the study of '' E. coli'' ribosomes. All ribosomal proteins have been isolated and many specific antibodies have been produced. These, together with electronic microscopy and the use of certain reactives, have allowed for the determination of the topography of the proteins in the ribosome. More recently, a near-complete (near)atomic picture of the ribosomal proteins is emerging from the latest high-resolution cryo-EM data (including ). Conservation Ribosomal prot ...

Endemic Fauna Of Greece
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] |
Cobitis
''Cobitis'' is a genus of small freshwater fish in the family Cobitidae from temperate and subtropical Eurasia. It contains the "typical spiny loaches", including the well-known spined loach of Europe. Similar spiny loaches, occurring generally south of the range of ''Cobitis'', are nowadays separated in ''Sabanejewia''.Perdices, A., Bohlen, J. & Doadrio, I.

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 ...

Arachthos River
The Arachthos ( el, Άραχθος) is a river in eastern Epirus, Greece. Its source is in the Pindus mountains, near the town Metsovo ( Ioannina regional unit). It is long, and its drainage area is . Its upper course is known as '' Metsovitikos''. From its confluence with the Dipotamos near the village of Batza it is called Arachthos. It flows towards the south, passing between the Athamanika and the Xerovouni mountains. In this place meets the Plaka Bridge, the largest one-arch stone bridge in Greece. It enters the large Pournari Reservoir, in the Arta regional unit, which is about 18 km² and prevents flooding of the city of Arta and also supplies water to most of Epirus. The town of Peta is situated near the dam. Arta, about 8 km downstream of the dam, is the largest town on the river. Arta's historic landmark is the stone Bridge of Arta over the Arachthos. The river continues through the lowlands south of Arta, and finally empties into the Ambracian Gulf near K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Parapatric
In parapatric speciation, two subpopulations of a species evolve reproductive isolation from one another while continuing to exchange genes. This mode of speciation has three distinguishing characteristics: 1) mating occurs non-randomly, 2) gene flow occurs unequally, and 3) populations exist in either continuous or discontinuous geographic ranges. This distribution pattern may be the result of unequal dispersal, incomplete geographical barriers, or divergent expressions of behavior, among other things. Parapatric speciation predicts that hybrid zones will often exist at the junction between the two populations. In biogeography, the terms parapatric and parapatry are often used to describe the relationship between organisms whose ranges do not significantly overlap but are immediately adjacent to each other; they do not occur together except in a narrow contact zone. Parapatry is a geographical distribution opposed to sympatry (same area) and allopatry or peripatry (two similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thiamis River
The Thyamis ( el, Θύαμις), also known as Glykys (Γλυκύς) or Kalamas (Καλαμάς), is a river in the Epirus region of Greece. It flows into the Ionian Sea. It is long, and its drainage area is about , over 99% of which on Greek territory. The names of the Chameria region (''Tsamouria'' in Greek), as well as the Chams, derive from the river's name. Thyamis in ancient Greece was mentioned by Pausanias as forming the boundary between Thesprotis and Kestrine. In addition, Suda and Ptolemaeus mentioned it. Some Renaissance scholars believed that the English River Thames owed its name to the River Thyamis, as early Celtic tribes were thought to have migrated from the Epirus region to England. While this belief influenced the modern spelling of the English river's name, it is no longer regarded as credible. Geography The source of the river is near the village Kalpaki, in the northwestern part of the Ioannina regional unit. It flows south at first, and turns southwes ...

Louros River
The Louros ( el, Λούρος) is a river in the Epirus region, in northwestern Greece. It is long, and its drainage area is . It emerges from the ground in a large spring located immediately north of the village of Vouliasta, in Ioannina regional unit. It flows south through a canyon, and then a dam followed by a hydroelectric power station. The Louros flows past town of Filippiada, forming the boundary between Arta regional unit and Preveza regional unit. The river then veers east into the Preveza regional unit, flowing through the municipality of Louros, named after the river. The Louros then empties into the marshes at the northern end of the Ambracian Gulf The Ambracian Gulf, also known as the Gulf of Arta or the Gulf of Actium, and in some official documents as the Amvrakikos Gulf ( el, Αμβρακικός κόλπος, translit=Amvrakikos kolpos), is a gulf of the Ionian Sea in northwestern Greec ....
