Syrian Desert
The Syrian Desert ( ''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 about of West Asia, including parts of northern Saudi Arabia, eastern Jordan, southern Syria, and western Iraq. It accounts for about 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, or river valleys, generally dry riverbeds. 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. Several parts of the Syrian Desert have been referred to separately such as the ''Palmyrene desert'' around Palmyra, and the ''Homs desert''. The eastern sec ...

Desert
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. 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 climate, semi-arid. This includes much of the Polar regions of Earth, 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 strain the Rock (geology), 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 frag ...

Stipa Barbata
''Stipa'' is a genus of 141 species of large perennial hermaphroditic grasses collectively known as feather grass, needle grass, and spear grass. They are placed in the subfamily Pooideae and the tribe Stipeae, which also contains many species formerly assigned to ''Stipa'', which have since been reclassified into new genera. Many species are important forage crops. Several species such as ''Stipa brachytricha'', ''S. arundinacea'', ''S. splendens'', ''S. calamagrostis'', ''S. gigantea'' and ''S. pulchra'' are used as ornamental plants. One former species, esparto grass ('' Macrochloa tenacissima''), is used for crafts and extensively in paper making. It is a coarse grass with inrolled leaves and a panicle patterned inflorescence. Ecology Species of the genus ''Stipa'' can occur in grasslands or in savanna habitats. Certain specific prairie plant associations are dominated by grasses of the genus ''Stipa'', which genus often lends its name to the terminology of some prairie t ...

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 '' S ...

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, w ...

Tripoint
A triple border, tripoint, trijunction, triple point, or tri-border area is a geography, geographical point at which the boundaries of three countries or Administrative division, 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, Guatemala has two: one with Mexico and Belize, and one with Honduras and El Salvador; while Bangladesh and Mexico have one.

Sabkha
A sabkha () is a predominately coastal, supratidal mudflat or sandflat in which evaporite-saline minerals accumulate as the result of a 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 mineral 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.

Chert
Chert () is a hard, fine-grained sedimentary rock composed of microcrystalline or cryptocrystalline quartz, the mineral form of silicon dioxide (SiO2). Chert is characteristically of biological origin, but may also occur inorganically as a precipitation (chemistry), chemical precipitate or a diagenesis, diagenetic replacement, as in petrified wood. Chert is typically composed of the petrified remains of siliceous ooze, the biogenic sediment that covers large areas of the deep ocean floor, and which contains the silicon skeletal remains of diatoms, Dictyochales, silicoflagellates, and radiolarians. Precambrian cherts are notable for the presence of fossil cyanobacteria. In addition to Micropaleontology, microfossils, chert occasionally contains macrofossils. However, some chert is devoid of any fossils. Chert varies greatly in color, from white to black, but is most often found as gray, brown, grayish brown and light green to rusty redW.L. Roberts, T.J.
