Sinai Leopard
The Arabian leopard (''Panthera pardus nimr'') is a leopard subspecies native to the Arabian Peninsula. It has been listed as Critically Endangered on the IUCN Red List since 1996 as fewer than 200 wild individuals were estimated to be alive in 2006. The population is severely fragmented. Subpopulations are isolated and not larger than 50 mature individuals. The population is thought to decline continuously. The Arabian leopard is the smallest leopard subspecies. It was tentatively affirmed as a distinct subspecies by genetic analysis of a single wild leopard from South Arabia, which appeared most closely related to the African leopard. Taxonomic history ''Felis pardus nimr'' was the scientific name proposed by Wilhelm Hemprich and Christian Gottfried Ehrenberg in 1830 for a leopard from Arabia. ''Panthera pardus jarvisi'', proposed by Reginald Innes Pocock in 1932, was based on a leopard skin from the Sinai Peninsula. In the early 1990s, a phylogeographic analysis was ...

Ein Gedi
Ein Gedi ( he, עֵין גֶּדִי, ), also spelled En Gedi, meaning "spring of the kid", is an oasis, an archeological site and a nature reserve in Israel, located west of the Dead Sea, near Masada and the Qumran Caves. Ein Gedi, a kibbutz, was established nearby in 1954. Ein Gedi is a popular tourist attraction, and was listed in 2016 as one of the most popular nature sites in Israel. The site attracts about one million visitors a year. Etymology The name ''Ein Gedi'' is composed of two words (In both Arabic and Hebrew): ''ein'' means spring or a fountain and ''gǝdi'' means goat-kid. Ein Gedi thus means "kid spring" or "fountain of the kid". History and archaeology Neolithic At Mikveh Cave archaeologists found Pre-Pottery Neolithic A (PPNA) flint tools and an arrowhead.

Molecular Biology
Molecular biology is the branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions. The study of chemical and physical structure of biological macromolecules is known as molecular biology. Molecular biology was first described as an approach focused on the underpinnings of biological phenomena - uncovering the structures of biological molecules as well as their interactions, and how these interactions explain observations of classical biology. In 1945 the term molecular biology was used by physicist William Astbury. In 1953 Francis Crick, James Watson, Rosalind Franklin, and colleagues, working at Medical Research Council unit, Cavendish laboratory, Cambridge (now the MRC Laboratory of Molecular Biology), made a double helix model of DNA which changed the entire research scenario. They proposed the DNA structure based on previous research done by Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asir Mountains
The Asir Mountains ( ar, جِبَال عَسِيْر, '; (' Difficult')) is a mountainous region in southwestern Saudi Arabia running parallel to the Red Sea. It comprises areas in the Asir Region of Saudi Arabia, however it also generally includes areas near the Yemeni border.

Geology The mountains consist primarily of sedimentary rock, limestone, sandstone and shale, of Jurassic, Cretaceous and Paleogene origin on a Precambrian granitic basement. Climate and agriculture The region has the highest average rainfall of Saudi Arabia due to largely seasonal rain. Average rainfall can range from to over per year, in wet reg ...

Hijaz Mountains
The Hijaz Mountains ( ar, جِبَال ٱلْحِجَاز, Jibāl al-Ḥijāz ()) or "Hejaz Range" is a mountain range located in the Hejazi region of western Saudi Arabia. The range runs north and south along the eastern coast of the Red Sea, and can thus be treated as including the Midian Mountains, and being part of the Sarawat Mountains, broadly speaking. Geography The western coastal escarpment of the Arabian Peninsula is composed of two mountain ranges, the Hijaz Mountain to the north and the Asir Mountains farther south, with a gap between them near the middle of the peninsula's coastline. From an elevation of , the range declines towards the vicinity of the gap about . The mountain wall drops abruptly on the western side toward the Red Sea, leaving the narrow coastal plain of Tihamah. The eastern slopes are not as steep, allowing rare rainfall to help create oasis around the springs and wells of the few wadis. River or ''wadi'' The Hijaz Mountains have been conje ...

Glacial Maximum
An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers. Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet. Earth is currently in the Quaternary glaciation. Individual pulses of cold climate within an ice age are termed ''glacial periods'' (or, alternatively, ''glacials, glaciations, glacial stages, stadials, stades'', or colloquially, ''ice ages''), and intermittent warm periods within an ice age are called ''interglacials'' or ''interstadials''. In glaciology, ''ice age'' implies the presence of extensive ice sheets in both northern and southern hemispheres. By this definition, Earth is currently in an interglacial period—the Holocene. The amount of anthropogenic greenhouse gases emitted into Earth's oceans and atmosphere is predicted to prevent the next glacial period for the ...

Elba Protected Area
Gabal Elba ( ar, جَبَل علْبَة ' , ), or Elba Mountain, is a peak and, in general, includes the associated mountainous area in the Halaib Triangle of Northeast Africa. Despite being claimed by both Egypt and Sudan, the area is currently under Egyptian control. Geography The higher peaks in the area are Gabal Elba itself (), Gabal Shellal (), Gabal Shendib () and Gabal Shendodai (). Average annual rainfall in the region is less than , but orographic precipitation in and around Gabal Elba itself amounts to as much as . in the upper areas. This phenomenon owes to the vicinity of the Red Sea coast (some east of the mountains) and also to the fact that the coast, slightly curved to the east at this point, presents an unusually broad front to the sea across a strip of relatively flat land, which facilitates interception of moisture-laden north-east sea winds. This phenomenon is registered at its best in the northeast of the region, where Gabal Elba is located, which expla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
