Arabian Leopard
The Arabian leopard (''Panthera pardus nimr'') is the smallest leopard subspecies. It was described in 1830 and is native to the Arabian Peninsula, where it was widely distributed in rugged hilly and montane terrain until the late 1970s. Today, the population is severely fragmented and thought to decline continuously. In 2008, an estimated 45–200 individuals in three isolated subpopulations were restricted to western Saudi Arabia, Oman and Yemen. However, as of 2023, it is estimated that 100–120 in total remain, with 70-84 mature individuals, in Oman and Yemen, and it is possibly extinct in Saudi Arabia. The current population trend is suspected to be decreasing. 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 phyl ...

Biljurashi
Baljurashi () or Biljurashi () is a governorate in Al-Baha Province, south-western Saudi Arabia. Overview Baljurashi is a medium-sized governorate located in the Al-Baha Province of southwestern Saudi Arabia. It was historically the capital of the province that includes the tribes of Ghamid and Zahran. The governorate lies on the Sarawat Mountains and serves as a major summer resort, known for its pleasant climate and natural beauty. The temperature usually varies between in winter and in summer. The best time to visit is from mid-August until the end of September. A notable feature of Baljurashi is its forests, such as Raghadan Forest, which are so lush that visitors often find it hard to believe they are in Saudi Arabia. The governorate is referred to as "the land of one thousand and one watchtowers" and is known for its ancient seasonal camel trail, famously named "camel steps." These man-made steps were designed to help camels ascend the steep escarpment, and they stret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jebel Hafeet
Jabal Hafeet (, "Mount Hafeet"; variously transcribed Jabel or Jebal and Hafit – literally "empty mountain") is a mountain in the region of Tawam, on the border of the United Arab Emirates and Oman. It is often considered an outlier of the Hajar Mountains in Eastern Arabia due to its proximity to the main range. To the north is the UAE city of Al Ain, in the Eastern Region of the Emirate of Abu Dhabi, and the adjacent Omani town of Al-Buraimi. The sole mountain in the Emirate of Abu Dhabi, and one of the highest mountains in the country, it has given its name to a period in UAE history, the Hafit Period of the Bronze Age (3200 to 2600 BCE), because of the discovery of a cluster of important beehive tombs at its foothills. As of 2017, the mountain is recognised as being part of a national park, and was incorporated into the Sheikh Zayed Network of Protected Areas in 2018. Climate Jebel Hafeet has a hot desert climate (BWh) according to the Köppen climate classification ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asir Mountains
The Asir Mountains (, '; (' Difficult')) is a mountainous region in southwestern Saudi Arabia running parallel to the Red Sea. It comprises areas in the Asir Province, but generally, it also includes areas near the border with Yemen.

Broadly, they are part of the Sarawat Mountains, defining the latter as the mountain range which runs parallel to the Tihamah throughout the western portion of the Arabian Peninsula, particularly the western parts of Saudi Arabia and Yemen. 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 regions. The eastern plains and plateaus receive much ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Molecular Biology
Molecular biology is a branch of biology that seeks to understand the molecule, molecular basis of biological activity in and between Cell (biology), cells, including biomolecule, biomolecular synthesis, modification, mechanisms, and interactions. Though cells and other microscopic structures had been observed in living organisms as early as the 18th century, a detailed understanding of the mechanisms and interactions governing their behavior did not emerge until the 20th century, when technologies used in physics and chemistry had advanced sufficiently to permit their application in the biological sciences. The term 'molecular biology' was first used in 1945 by the English physicist William Astbury, who described it as an approach focused on discerning the underpinnings of biological phenomena—i.e. uncovering the physical and chemical structures and properties of biological molecules, as well as their interactions with other molecules and how these interactions explain observ ...

Camera Trap
A camera trap is a camera that is automatically triggered by motion in its vicinity, like the presence of an animal or a human being. It is typically equipped with a motion sensor—usually a passive infrared (PIR) sensor or an active infrared (AIR) sensor using an infrared light beam. Camera traps are a type of remote cameras used to capture images of wildlife with as little human interference as possible. Camera trapping is a method for recording wild animals when researchers are not present, and has been used in ecological research for decades. In addition to applications in hunting and wildlife viewing, research applications include studies of nest ecology, detection of rare species, estimation of population size and species richness, and research on habitat use and occupation of human-built structures. Since the introduction of commercial infrared-triggered cameras in the early 1990s, their use has increased. With advancements in the quality of camera equipment, this meth ...
