Edough Ribbed Newt
''Pleurodeles poireti'', the Edough ribbed newt or Poiret's newt, is a species of salamander in the family Salamandridae. It is found only in the Edough Massif, in the north east of Algeria. The natural habitats are of these newts are rivers, intermittent rivers, swamps, freshwater marshes, intermittent freshwater marshes, cisterns and ponds. They are 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 .... The true ''P. poireti'' newts are restricted to the Edough Massif area, in Numidia. Formerly, this species was confused with the Algerian ribbed newt ''Pleurodeles nebulosus'', which has a much wider distribution.

Salamander
Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults. All ten extant salamander families are grouped together under the order Urodela. Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm. Salamanders rarely have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs. Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults. This group of amphibians is capable of regenerating lost lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salamandridae
Salamandridae is a family of salamanders consisting of true salamanders and newts. Salamandrids are distinguished from other salamanders by the lack of rib or costal grooves along the sides of their bodies and by their rough skin. Their skin is very granular because of the number of poison glands. They also lack nasolabial grooves. Most species of Salamandridae have moveable eyelids but lack lacrimal glands. Nearly all salamandrids produce a potent toxin in their skin, with some species being deadly to many other animal species. With a few exceptions, salamandrids have patterns of bright and contrasting colours, most of these are to warn potential predators of their toxicity. They have four well-developed limbs, with four toes on the fore limbs, and (in most cases) five toes on the hind limbs. They vary from in length. Many species within this family reproduce by method of internal fertilization. Additionally, there are many species-specific courtship rituals that males perform ...

Edough Massif
The Edough Massif, Edough Mountains or Djebel Edough ( ar, جبل إيدوغ, links=, lit=, translit=Ǧabal Īdūḡ; ber, script=Tfng, ⴰⴷⵔⴰⵔ ⵏ ⴷⴷⵓⵖ, links=, lit=, translit=, label=) is a mountain range of the Maghreb area in Northern Africa. Geography These mountains are a segment of the Tell Atlas alpine chain of eastern Algeria that is part of the wider Atlas Range. The Edough Massif stretches between the Cap de Garde and the Cap de Fer. The highest point of the massif is the Bou Zizi (1008 m), located between Annaba and El Marsa. Geologically, these mountains are a Miocene crystalline metamorphic core complex. Ecology The Edough Massif has a Mediterranean forest cover where the cork oak ''(Quercus suber)'', a hardy Mediterranean tree, predominates. Snow is not rare in the winter and the mountains are often covered with fog, which allows ferns to grow among the undergrowth. The forest of the Edough Massif is very vulnerable to wildfires.

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] |
River
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as Stream#Creek, creek, Stream#Brook, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to Geographical feature, geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "Burn (landform), burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from Precipitation (meteorology), precipitation through a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Swamp
A swamp is a forested wetland.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p. Swamps are considered to be transition zones because both land and water play a role in creating this environment. Swamps vary in size and are located all around the world. The water of a swamp may be fresh water, brackish water, or seawater. Freshwater swamps form along large rivers or lakes where they are critically dependent upon rainwater and seasonal flooding to maintain natural water level fluctuations.Hughes, F.M.R. (ed.). 2003. The Flooded Forest: Guidance for policy makers and river managers in Europe on the restoration of floodplain forests. FLOBAR2, Department of Geography, University of Cambridge, Cambridge, UK. 96 p. Saltwater swamps are found along tropical and subtropical coastlines. Some swamps have hammock (ecology), hammocks, or dry-land protrusions, covered by aquatic vegetation, or vegetation that tolerates ...

Marsh
A marsh is a wetland that is dominated by herbaceous rather than woody plant species.Keddy, P.A. 2010. Wetland Ecology: Principles and Conservation (2nd edition). Cambridge University Press, Cambridge, UK. 497 p Marshes can often be found at the edges of lakes and streams, where they form a transition between the aquatic and terrestrial ecosystems. They are often dominated by grasses, rushes or reeds. If woody plants are present they tend to be low-growing shrubs, and the marsh is sometimes called a carr. This form of vegetation is what differentiates marshes from other types of wetland such as swamps, which are dominated by trees, and mires, which are wetlands that have accumulated deposits of acidic peat. Marshes provide habitats for many kinds of invertebrates, fish, amphibians, waterfowl and aquatic mammals. This biological productivity means that marshes contain 0.1% of global sequestered terrestrial carbon. Moreover, they have an outsized influence on climate resi ...

Pond
A pond is an area filled with water, either natural or artificial, that is smaller than a lake. Defining them to be less than in area, less than deep, and with less than 30% emergent vegetation helps in distinguishing their ecology from that of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers), or they can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bottom mud and surface film. The size and depth of ponds often varies greatly with the time of year; many ponds are produced by spring flooding from rivers. Ponds may be ...

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 ...

Numidia
Numidia ( Berber: ''Inumiden''; 202–40 BC) was the ancient kingdom of the Numidians located in northwest Africa, initially comprising the territory that now makes up modern-day Algeria, but later expanding across what is today known as Tunisia, Libya, and some parts of Morocco. The polity was originally divided between the Massylii in the east and the Masaesyli in the west. During the Second Punic War (218–201 BC), Masinissa, king of the Massylii, defeated Syphax of the Masaesyli to unify Numidia into one kingdom. The kingdom began as a sovereign state and later alternated between being a Roman province and a Roman client state. Numidia, at its largest extent, was bordered by Mauretania to the west, at the Moulouya River, Africa Proconsularis to the east, the Mediterranean Sea to the north, and the Sahara to the south. It was one of the first major states in the history of Algeria and the Berbers. History Independence The Greek historians referred to these peoples as ...

Algerian Ribbed Newt
The Algerian ribbed newt (''Pleurodeles nebulosus'') is a species of salamander in the family Salamandridae found in Algeria and Tunisia. The natural habitats of this newt are rivers, intermittent rivers, swamps, cisterns, freshwater marshes, intermittent freshwater marshes, and ponds. It is threatened by habitat destruction. Taxonomy Formerly, this species was confused with ''Pleurodeles poireti''. Carranza and Wade (2004) found out that most North African ''Pleurodeles'' species that had previously been referred to as ''P. poireti'' were in fact ''Pleurodeles nebulosus'', an altogether different species. The true ''P. poireti'' newts are found only on the Edough Massif, in northeast Algeria. Description The Algerian ribbed newt is a medium-sized species growing to a length of about . The head is flattened and has small eyes and a rounded snout. The body is somewhat flattened and the tail of the male is longer than that of the female. In the breeding season, fins grow above and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
