Ochradenus Socotranus
''Ochradenus socotranus'' is a species of plant in the Resedaceae family. It is a shrub endemic to the islands of Socotra and Samhah in Yemen's Socotra Archipelago. Its natural habitat is dry rocky slopes from 10 to 700 metres elevation. The species is most closely related to ''Ochradenus arabicus'' from the Arabian Peninsula and '' O. baccatus'' from the Arabian Peninsula and northeastern Africa. It is dioecious Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is ... like ''O. arabicus'', but differs in having fleshy fruits and dull rather than glossy seeds. ''O. baccatus'' has hermaphrodite flowers and rugose seeds.

Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...

Endemism
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or b ...

Socotra
Socotra, locally known as Saqatri, is a Yemeni island in the Indian Ocean. Situated between the Guardafui Channel and the Arabian Sea, it lies near major shipping routes. Socotra is the largest of the six islands in the Socotra archipelago as it comprises around 95% of the landmass of the archipelago. It lies south of the Arabian Peninsula and east of the Horn of Africa. The inhabitants of the island are called Soqotri people, Socotrans, and they speak Arabic and Soqotri language, Soqotri. Socotra is home to a high number of unique species that are endemism, endemic to it. Up to a third of its plant life is unique. Due to the island's unusual geography, it has been described as "the most alien-looking place on Earth". The island measures in length and across at its widest. In 2008, Socotra was recognised as a UNESCO World Heritage Site. The island is under the control of the Southern Transitional Council (STC), a United Arab Emirates-backed, pro-Presidential Leadership Co ...

Socotra Archipelago
The Socotra Archipelago ( '), officially the Socotra Archipelago Governorate ( '), abbreviated to Socotra Governorate ( '), is one of the governorates of Yemen. It includes a number of islands in the Indian Ocean south of mainland Yemen, the largest of which is Socotra. Etymology Scholars' views vary regarding the origin of the name of the island. The name Socotra may derive from: * A Greek name that is derived from the name of a South Arabian tribe mentioned in Sabaic and Ḥaḑramitic inscriptions as Dhū-Śakūrid (S³krd). * The Arabian terms suq, market, and qutra, a vulgar form of qatir, which refers to dragon's blood. History Since before British rule, Socotra had been part of the Mahra Sultanate but later the British captured it and made Socotra a part of Bombay Presidency in British India and so it remained till 1937. In 1937 British made it part of Aden Protectorate. With the independence of South Yemen in 1967, the archipelago was attached to the Aden Gov ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arabian Peninsula
The Arabian Peninsula (, , or , , ) or Arabia, is a peninsula in West Asia, situated north-east of Africa on the Arabian plate. At , comparable in size to India, the Arabian Peninsula is the largest peninsula in the world. Geographically, the Arabian Peninsula comprises Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, the United Arab Emirates (UAE) and Yemen, as well as southern Iraq and Jordan. The largest of these is Saudi Arabia. In the Roman era, the Sinai Peninsula was also considered a part of Arabia. The Arabian Peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and south-west, the Persian Gulf and the Gulf of Oman to the north-east, the Levant and Mesopotamia to the north and the Arabian Sea and the Indian Ocean to the south-east. The peninsula plays a critical geopolitical role in the Arab world and globally due to its vast reserves of petroleum, oil and natural gas. Before the mod ...

Dioecious
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...
