Al Badia
The Syrian Desert ( ar, بادية الشام ''Bādiyat Ash-Shām''), also known as the North Arabian Desert, the Jordanian steppe, or the Badiya, is a region of desert, semi-desert and steppe covering of the Middle East, including parts of southern Syria, eastern Jordan, northern Saudi Arabia, and western Iraq. It accounts for 85% of the land area of Jordan and 55% of Syria. To the south it borders and merges into the Arabian Desert. The land is open, rocky or gravelly desert pavement, cut with occasional wadis. Location and name The desert is bounded by the Orontes Valley and the volcanic field of Harrat al-Shamah to the west, and by the Euphrates to the east. In the north, the desert gives way to the more fertile areas and to the south it runs into the deserts of the Arabian Peninsula. Some sources equate the Syrian Desert with the ''"Hamad Desert"'' while others limit the name ''Hamad'' to the southern central plateau. A few consider the Hamad to be the whole region and ...

Desert
A desert is a barren area of landscape where little precipitation occurs and, consequently, living conditions are hostile for plant and animal life. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night put strains on the rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atriplex Leucoclada
''Atriplex'' () is a plant genus of about 250 species, known by the common names of saltbush and orache (; also spelled orach). It belongs to the subfamily Chenopodioideae of the family Amaranthaceae ''s.l.''. The genus is quite variable and widely distributed. It includes many desert and seashore plants and halophytes, as well as plants of moist environments. The generic name originated in Latin and was applied by Pliny the Elder to the edible oraches. The name saltbush derives from the fact that the plants retain salt in their leaves; they are able to grow in areas affected by soil salination. Description Species of plants in genus ''Atriplex'' are annual or perennial herbs, subshrubs, or shrubs. The plants are often covered with bladderlike hairs, that later collapse and form a silvery, scurfy or mealy surface, rarely with elongate trichomes. The leaves are arranged alternately along the branches, rarely in opposite pairs, either sessile or on a petiole, and are som ...

Caroxylon Vermiculatum
''Caroxylon vermiculatum'', commonly known as Mediterranean saltwort, is a perennial plant in the family Amaranthaceae. It has many synonyms, including ''Salsola vermiculata'' and ''Nitrosalsola vermiculata''. It is native to arid and semi-arid regions of the Middle East, North Africa and southern Europe where it is used as a fodder plant for livestock. Description ''Caroxylon vermiculatum'' is a small, greyish, much-branched shrub ranging in height from . The branches themselves branch repeatedly and are wiry and woody at the base. The leaves are tiny and scale-like, clasping the stem and covered with minute hairs. The inflorescence is a leafy spike with solitary flowers in the axils of the leaves. The flowers have persistent, pinkish, winged sepals and no petals and are about in diameter. Taxonomy The species was first described, as ''Salsola vermiculata'', in 1753 by Carl Linnaeus in ''Species Plantarum''. Phylogenetic research led to the re-circumscription of the genus ''Sa ...

Climax Species
Climax species, also called late seral, late-successional, K-selected or equilibrium species, are plant species that can germinate and grow with limited resources; e.g., they need heat exposure or low water availability. They are the species within forest succession that are more adapted to stable and predictable environments, and will remain essentially unchanged in terms of species composition for as long as a site remains undisturbed. The seedlings of climax species can grow in the shade of the parent trees, ensuring their dominance indefinitely. The presence of climax species can also reduce the prevalence of other species within an ecosystem. However, a disturbance, such as fire, may kill the climax species, allowing pioneer or earlier successional species to re-establish for a time. They are the opposite of pioneer species, also known as ruderal, fugitive, opportunistic or R-selected species, in the sense that climax species are good competitors but poor colonizers, wh ...

Tripoint
A tripoint, trijunction, triple point, or tri-border area is a geographical point at which the boundaries of three countries or subnational entities meet. There are 175 international tripoints as of 2020. Nearly half are situated in rivers, lakes or seas. On dry land, the exact tripoints may be indicated by markers or pillars, and occasionally by larger monuments. Usually, the more neighbours a country has, the more international tripoints that country has. China with 16 international tripoints and Russia with 11 to 14 lead the list of states by number of international tripoints. Other countries, like Brazil, India and Algeria, have several international tripoints. Argentina has four international tripoints. South Africa, Pakistan and Nigeria have three international tripoints while Bangladesh and Mexico have only one. Within Europe, landlocked Austria has nine tripoints, among them two with Switzerland and Liechtenstein. Island countries, such as Japan and Australia, have no ...

Sabkha
A sabkha ( ar, سبخة) is a coastal, supratidal mudflat or sandflat in which evaporite-saline minerals accumulate as the result of semiarid to arid climate. Sabkhas are gradational between land and intertidal zone within restricted coastal plains just above normal high-tide level. Within a sabkha, evaporite-saline minerals sediments typically accumulate below the surface of mudflats or sandflats. Evaporite-saline minerals, tidal-flood, and aeolian deposits characterize many sabkhas found along modern coastlines. The accepted type locality for a sabkha is at the southern coast of the Persian Gulf, in the United Arab Emirates.Neuendorf, K.K.E., J.P. Mehl, Jr., and J.A. Jackson, eds.
