Arouss Al Ayn
The Near Eastern fire salamander (''Salamandra infraimmaculata''), in Arabic ''arouss al-ayn'', is a species of salamander in the family Salamandridae found in Iran, Iraq, Turkey, Syria, Lebanon, and Israel. Its natural habitats are subtropical dry shrubland and forests, often near rivers and freshwater springs. It is threatened by habitat loss. Description This species is a black salamander with yellow spots on its back as warning coloration, but none on its belly. It has smooth, shiny skin, usually with four large, yellow blotches on the head. Various subspecies have different patterns of colours, for example, ''S. i. orientalis'' is virtually identical to ''S. i. infraimmaculata'', but has a large number of yellow dots all over its body. However, the validity of this subspecies is in question. Another subspecies, ''S. i. semenovi'', has a more rounded head and rose-shaped spots over the top part of the body. It can grow to in length with ''S. i. infraimmaculata'' being the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eduard Von Martens
Eduard von Martens (18 April 1831 – 14 August 1904) also known as ''Carl'' or ''Karl Eduard von Martens'', was a German zoologist. Born in Stuttgart in 1831, von Martens attended university in University of Tübingen, Tübingen, where he graduated in 1855. He then moved to Berlin, where he would be based for the remainder of his career, both at the Zoological Museum of the Berlin University (from 1855) and, from 1859 on, at the . In 1860, he embarked on the ''Thetis'' expedition of the Prussian expedition to Eastern Asia. When the expedition returned to Europe in 1862, von Martens continued to travel around Maritime Southeast Asia for 15 months. He published the results of the "Thetis" expedition in two volumes, constituting the Zoologischer Theil of the "Preussische Expedition nach Ost-Asien." Vol. ii, consisting of 447 pages and 22 plates, contained a very full account of the land molluscs. Back in Berlin, von Martens was curator of the malacological and other invertebrate ...

Aestivate
Aestivation ( la, aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, the hot dry season, which are often the summer months. Invertebrate and vertebrate animals are known to enter this state to avoid damage from high temperatures and the risk of desiccation. Both terrestrial and aquatic animals undergo aestivation. Fossil records suggest that aestivation may have evolved several hundred million years ago. Physiology Organisms that aestivate appear to be in a fairly "light" state of dormancy, as their physiological state can be rapidly reversed, and the organism can quickly return to a normal state.

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 ...

Egg (biology)
An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the animal hatches. Most arthropods such as insects, vertebrates (excluding live-bearing mammals), and mollusks lay eggs, although some, such as scorpions, do not. Reptile eggs, bird eggs, and monotreme eggs are laid out of water and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a warm and favorable temperature range while the embryo grows. When the embryo is adequately developed it hatches, i.e., breaks out of the egg's shell. Some embryos have a temporary egg tooth they use to crack, pip, or break the eggshell or covering. The largest recorded egg is from a whale shark and was in size. Whale shark eggs typically hatch within the mother. At and up to , the o ...

Hill
A hill is a landform that extends above the surrounding terrain. It often has a distinct Summit (topography), summit. Terminology The distinction between a hill and a mountain is unclear and largely subjective, but a hill is universally considered to be not as tall, or as Grade (slope), steep as a mountain. Geographers historically regarded mountains as hills greater than above sea level, which formed the basis of the plot of the 1995 film ''The Englishman who Went up a Hill but Came down a Mountain''. In contrast, hillwalkers have tended to regard mountains as peaks above sea level. The ''Oxford English Dictionary'' also suggests a limit of and Whittow states "Some authorities regard eminences above as mountains, those below being referred to as hills." Today, a mountain is usually defined in the UK and Ireland as any summit at least high, while the official UK government's definition of a mountain is a summit of or higher. Some definitions include a topographical pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Quercus Suber
''Quercus suber'', commonly called the cork oak, is a medium-sized, evergreen oak tree in the section ''Quercus'' sect. ''Cerris''. It is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and as the cores of cricket balls. It is native to southwest Europe and northwest Africa. In the Mediterranean basin the tree is an ancient species with fossil remnants dating back to the Tertiary period. It endures drought and makes little demand on the soil quality and is regarded as a defence against desertification. Cork oak forests are home to a multitude of animal and plant species. Since cork is increasingly being displaced by other materials as a bottle cap, these forests are at risk as part of the cultural landscape and animal species such as the Iberian lynx are threatened with extinction. Description General appearance and bark The cork oak grows as an evergreen tree, reaching an average height of or in rare cases up to 25 m and a tr ...

Mount Carmel
Mount Carmel ( he, הַר הַכַּרְמֶל, Har haKarmel; ar, جبل الكرمل, Jabal al-Karmil), also known in Arabic as Mount Mar Elias ( ar, link=no, جبل مار إلياس, Jabal Mār Ilyās, lit=Mount Saint Elias/Elijah), is a coastal mountain range in northern Israel stretching from the Mediterranean Sea towards the southeast. The range is a UNESCO biosphere reserve. A number of towns are situated there, most notably the city of Haifa, Israel's third largest city, located on the northern and western slopes. Etymology The word ''karmel'' means "garden-land" and is of uncertain origin. It is either a compound of ''kerem'' and ''el'', meaning "vineyard of El (deity), God" or a clipping of ''kar male,'' meaning "full kernel." Martin Jan Mulder suggested a third etymology, that of ''kerem + l'' with the lamed a wiktionary:sufformative, sufformative, but this is considered unlikely as evidence for the existence of a lamed sufformative is weak.

Galilee
Galilee (; he, הַגָּלִיל, hagGālīl; ar, الجليل, al-jalīl) is a region located in northern Israel and southern Lebanon. Galilee traditionally refers to the mountainous part, divided into Upper Galilee (, ; , ) and Lower Galilee (, ; , ). ''Galilee'' refers to all of the area that is north of the Mount Carmel-Mount Gilboa ridge and south of the east–west section of the Litani River. It extends from the Israeli coastal plain and the shores of the Mediterranean Sea with Acre in the west, to the Jordan Rift Valley to the east; and from the Litani in the north plus a piece bordering on the Golan Heights all the way to Dan at the base of Mount Hermon in the northeast, to Mount Carmel and Mount Gilboa in the south. This definition includes the plains of the Jezreel Valley north of Jenin and the Beth Shean Valley, the valley containing the Sea of Galilee, and the Hula Valley, although it usually does not include Haifa's immediate northern suburbs.

Dan (ancient City)
Dan ( he, דן) is an ancient city mentioned in the Hebrew Bible, described as the northernmost city of the Kingdom of Israel, and belonging to the tribe of Dan. The city is identified with a tell located in Upper Galilee, northern Israel, known as Tel Dan (; "Mound of Dan") in Hebrew. Identification and names The Hebrew Bible states that prior to its conquest by the tribe of Dan the site was known as Laish with variant spellings within the Books of Joshua, Judges and Isaiah. In it is called Leshem, which means "jewel". has the alternative name ''Laishah'' in a number of translations. Rabbinic works, and writers like Philostorgius, Theodoret, Benjamin of Tudela and Samuel ben Samson, all incorrectly identified Dan or Laish, with Banias (Paneas).Saulcy, 1854, pp537538 Eusebius of Caesarea more accurately places Dan/Laish in the vicinity of Paneas at the fourth mile on the route to Tyre. 19th century Swiss traveler Johann Ludwig Burckhardt identified the source of the Jordan ...
