Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Skeleton Coast
The Skeleton Coast is the northern part of the Atlantic coast of Namibia and south of Angola from the Kunene River south to the Swakop River, although the name is sometimes used to describe the entire Namib Desert coast. The indigenous San people (formerly known as Bushmen), of the Namibian interior called the region "The Land God Made in Anger", while Portuguese sailors once referred to it as "The Gates of Hell". On the coast, the upwelling of the cold Benguela current gives rise to dense ocean fogs (called ''cassimbo'' by the Angolans) for much of the year. The winds blow from land to sea, rainfall rarely exceeds annually, and the climate is highly inhospitable. There is a constant, heavy surf on the beaches. In the days before engine-powered ships and boats, it was possible to get ashore through the surf but impossible to launch from the shore. The only way out was by going through a marsh hundreds of kilometres long and only accessible via a hot and arid desert. The ...

Namib
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured arid or semi-arid conditions for roughly 55–80 million years, the Namib may be the oldest desert in the world and conta ...

Kaokoveld
The Kaokoveld Desert is a coastal desert of northern Namibia and southern Angola. Setting The Kaokoveld Desert occupies a coastal strip covering , from 13° to 21°S and is bounded by the Atlantic Ocean to the west, the Namibian savanna woodlands to the east, and the Namib Desert to the south. It includes the Moçâmedes Desert of southern Angola. The Kaokoveld is a harsh desert of drifting sandunes and rocky mountains. It receives most of its rainfall during the summer, which distinguishes it from the adjacent Namib Desert to the south, which receives most of its rain during the winter. The Kunene River is the only permanent watercourse but many dry riverbeds (including the Hoanib, Hoarusib and Khumib Rivers) carry moisture through the desert and are home to animals including elephants, black rhinos, and giraffe. Other than those the area is ancient desert sand, moistened by occasional coastal fog. Flora The Kaokoveld is home to ''Welwitschia mirabilis'', a plant that has n ...

Caudex
A caudex (plural: caudices) of a plant is a stem, but the term is also used to mean a rootstock and particularly a basal stem structure from which new growth arises.pages 456 and 695 In the strict sense of the term, meaning a stem, "caudex" is most often used with plants that have a different stem morphology from the typical angiosperm dicotyledon stem: examples of this include palms, ferns, and cycads. The related term caudiciform, literally meaning stem-like, is sometimes used to mean pachycaul, thick-stemmed. Etymology The term is from the Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ... ''caudex'', a noun meaning "tree trunk".

Crassothonna Clavifolia
''Crassothonna clavifolia'' (previously ''Othonna clavifolia'') is a species of flowering plant in the family Asteraceae. It is found only in Namibia. Its natural habitat is rocky areas. It is threatened by habitat loss. Description This species is a low-growing succulent with grey, trailing branches and squat, cylindrical or barrel-like leaves. The yellow, daisy-like flowers grow on long stalks. The specific epithet, ''clavifolia'', is from the Latin words ''clava'' meaning a club and ''folia'' meaning leaves, referring to the club-shape of the leaves. Taxonomy This species was described by Hermann Wilhelm Rudolf Marloth in 1910 as ''Othonna clavifolia,'' however, the genus was changed from ''Othonna'' by Nordenstam et al., who erected the new genus ''Crassothonna'' for a distinct clade of ''Othonna'' species. The new name for this species is therefore ''Crassothonna clavifolia'' (Marloth) B.Nord. Distribution and habitat This species is found from the northwest of the Ri ...

Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...
