Armatocereus Rauhii
''Armatocereus rauhii'' is a tall, branched columnar species of cactus endemic to the north of Peru on the western slopes of the Andes. Description ''Armatocereus'' is a tall, treelike cactus, bluish to greyish green in colour, usually with a trunk to about high followed by upright branches. Depending on the subspecies, it reaches a maximum height of , with branches thick. The stems have 6–12 ribs. The areoles bear about 6–7 short spines, only long – somewhat more spines in the case of subspecies ''balsasensis''. The flowers are long, carmine or purple in colour, with black to red spines on the floral tube. Taxonomy The species was first described by Curt Backeberg in 1957. The specific epithet ''rauhii'' honours Werner Rauh. Two species described by Friedrich Ritter in 1981, ''Armatocereus balsasensis'' and ''Armatocereus arduus'', are included in this species, as synonyms of ''A. rauhii'' subsp. ''balsasensis'', by some sources. Other sources maintain ''A. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
A cactus (, or less commonly, cactus) is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word ''cactus'' derives, through Latin, from the Ancient Greek word (''káktos''), a name originally used by Theophrastus for a spiny plant whose identity is now not certain. Cacti occur in a wide range of shapes and sizes. Although some species live in quite humid environments, most cacti live in habitats subject to at least some drought. Many live in extremely dry environments, even being found in the Atacama Desert, one of the driest places on Earth. Because of this, cacti show many adaptations to conserve water. For example, almost all cacti are succulents, meaning they have thickened, fleshy parts adapted to store water. Unlike many other succulents, the stem is the only part of most cacti where this vital process takes place. Most species of cacti have lost true leaves, retaining only spin ...

Amazonas Region
Amazonas () is a department and region in northern Peru bordered by Ecuador on the north and west, Cajamarca on the west, La Libertad on the south, and Loreto and San Martín on the east. Its capital is the city of Chachapoyas. With a landscape of steep river gorges and mountains, Amazonas is the location of Kuelap, a huge stone fortress enclosing more than 400 stone structures; it was built on a mountain about 3,000 meters high, starting about 500 AD and was occupied to the mid-16th century. It is one of Peru's major archeological sites. Geography The department of Amazonas consists of regions covered by rainforests and mountain ranges. The rainforest zone predominates (72.93%) and it extends to the north over its oriental slope, up to the border with Ecuador in the summits of the Cordillera del Cóndor. The mountain range zone is located in the southern provinces of the Amazonas Region and it only includes 27.07% of its whole territorial surface. One of the factors t ...

Armatocereus
''Armatocereus'' (from Latin ''armatus'', "armed" and ''cereus'', "pliant/soft") is a genus of mostly tree-like cacti from South America (Ecuador and Peru). These species have a conspicuous constriction at the end of the annual growth. The flowers are mostly white, with a more or less spiny ovary. The fruits are mostly spiny. Description ''Armatocereus'' species are columnar cacti, bushlike or treelike, with cylindrical upright branched stems. The stems have 5–12 distinct ribs, and are made up of sections with a narrower "neck" between them, corresponding to annual growth. The large areoles bear strong spines, rarely few or none. The narrow tubular flowers appear at night, and have a spiny ovary and floral tube and white petals (red in '' A. rauhii''). The red or green fruit is large, globular or ovoid, with strong spines that are lost on maturity. It contains large black seeds, ovoid or kidney-shaped.

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piura Region
Piura () is a coastal department and region in northwestern Peru. The region's capital is Piura and its largest port cities, Paita and Talara, are also among the most important in Peru. The area is known for its tropical and dry beaches. It is the most populous department in Peru, its twelfth smallest department, and its fourth-most densely populated department, after Tumbes, La Libertad, and Lambayeque. The country's latest decentralization program is in hiatus after the proposal to merge departments was defeated in the national referendum in October 2005. The referendum held on October 30, 2005, as part of the ongoing decentralization process in Peru, to decide whether the region would merge with the current regions of Lambayeque and Tumbes to create a new ''Región Norte'' was defeated. Geography The Piura Region is bordered to the north by the Tumbes Region and Ecuador, to the east by Cajamarca Region, to the south by the Lambayeque Region, and to the west by ...

Lambayeque Region
Lambayeque () is a department and region in northwestern Peru known for its rich Moche and Chimú historical past. The region's name originates from the ancient pre-Inca civilization of the '' Lambayeque''. It is the second-smallest department in Peru after Tumbes, but it is also its most densely populated department and its eighth most populous department. Etymology The name ''Lambayeque'' is a Spanish derivation of the god ''Yampellec'', said to have been worshipped by the first Lambayeque king, ''Naymlap''. The Spanish gave the name to the early people. Geography The territory of the department of Lambayeque is made up of wide plains irrigated by rivers from the Andes; in most of the arid area, irrigation is needed to support any farming. The fertile river valleys produce half of the sugar cane crop of Peru. In addition, Lambayeque and the department of Piura provide most of the rice crops consumed in Peru. Increased agricultural harvest is expected with completion of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, '' Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia l ...
