Flowering Desert (Chile)
A desert bloom is a Climate, climatic phenomenon that occurs in various deserts around the world. The phenomenon consists of the blossoming of a wide variety of flowers during early-mid spring in years when rainfall is unusually high. The blossoming occurs when the unusual level of rainfall reaches seeds and bulbs that have been in a latent or dormant state, and causes them to germination, germinate and flower in early spring. It is accompanied by the proliferation of insects, birds and small species of lizards. Around the world Chile In the Atacama Desert, a desert bloom () occurs between the months of September and November in years when rainfall is unusually high. Normally, the Atacama Desert receives less than of rain a year. At its height, the phenomenon can be seen from just south of the city of Vallenar, Chile, Vallenar to just north of the city of Copiapó, Chile, Copiapó throughout the coastal valleys and Chilean Coast Range from September to November.

Flowering Plants
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Motorsport
Motorsport or motor sport are sporting events, competitions and related activities that primarily involve the use of Car, automobiles, motorcycles, motorboats and Aircraft, powered aircraft. For each of these vehicle types, the more specific terms ''automobile sport'', ''motorcycle sport'', Motorboat#Racing, ''power boating'' and ''air sports'' may be used commonly, or officially by organisers and governing bodies. Different manifestations of motorsport with their own objectives and specific rules are called disciplines. Examples include Race track, circuit racing, rallying and Classic trial, trials. Governing bodies, also called sanctioning bodies, often have general rules for each discipline, but allow supplementary rules to define the character of a particular competition, series or championship. Groups of these are often categorised informally, such as by vehicle type, surface type or propulsion method. Examples of categories within a discipline are formula racing, stock car r ...

Pleurodema Thaul
''Pleurodema thaul'', the Chilean four-eyed frog is a species of frog in the family ''Leptodactylidae''. It is found in Argentina and Chile. Its natural habitats are subantarctic forests, temperate forests, temperate shrubland, temperate grassland, rivers, intermittent rivers, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, pastureland, plantations, rural gardens, urban areas, water storage areas, ponds, open excavations, sewage treatment areas, irrigated land, seasonally flooded agricultural land, and introduced vegetation. It is threatened by habitat loss. Individuals vary in size between 3 and 5 cm. They feed on insects and spiders. Reproduction occurs almost throughout the year. In Chile they are found from the Antofagasta region to the Aysén Region, while in Argentina they live in areas close to the Andes in the provinces of Neuquén, Rio Negro, and Chubut Chubut may refer to: * Chubut Province Chubut ( ...

Tuco-tuco
A tuco-tuco is a neotropical rodent in the family Ctenomyidae. Tuco-tucos belong to the only living genus of the family Ctenomyidae, ''Ctenomys'', but they include approximately 60 different species. The common name, "tuco-tuco", comes from the "tuc-tuc" sound they make while they dig their burrows."Southern Tuco-tuco (''Ctenomys australis'')" ARKive. 4 October 2013. The relationships among the species are debated by s. It has been described that they are in a state of "taxonomic chaos", but banded karyotypes have been used to help make progress on their taxonomic study.

Xerophile
A xerophile () is an extremophilic organism that can grow and reproduce in conditions with a low availability of water, also known as water activity. Physics Water activity, a thermodynamical value denoted , is defined as the partial water vapor pressure in equilibrium with the substance relative to (divided by) the (partial) vapor pressure of pure water at the same temperature: a_w \equiv \frac The thermodynamical water activity is thus equal to the relative humidity (RH), and the chemical activity of pure water is equal to one: When the atmosphere above a substance, or a solution, is undersaturated in water vapor , its water activity is lower than one. Xerophiles are "xerotolerant", meaning tolerant of dry conditions. They can often survive in environments with water activity below 0.8; above which is typical for most life on Earth. Typically xerotolerance is used with respect to matrix drying, where a substance has a low water concentration. These environments incl ...

Succulent Plant
In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil conditions. The word ''succulent'' comes from the Latin word ''sucus'', meaning "juice" or "sap". Succulents may store water in various structures, such as leaf, leaves and Plant stem, stems. The water content of some succulent organs can get up to 90–95%, such as ''Glottiphyllum semicyllindricum'' and ''Mesembryanthemum barkleyii''. Some definitions also include roots, thus geophytes that survive unfavorable periods by dying back to underground storage organs (caudex) may be regarded as succulents. The habitats of these water-preserving plants are often in areas with high temperatures and low rainfall, such as deserts, but succulents may be found even in Alpine climate, alpine ecosystems growing in rocky or sandy soil. Succulents are characterized by their ability to thrive on limited water sources, such as mist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cactus
A cactus (: cacti, cactuses, or less commonly, cactus) is a member of the plant family Cactaceae (), a family of the order Caryophyllales comprising about 127 genera with some 1,750 known species. 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. They are native to the Americas, ranging from Patagonia in the south to parts of western Canada in the north, with the exception of ''Rhipsalis baccifera'', which is also found in Africa and Sri Lanka. Cacti are adapted to live in very dry environments, including 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 ...

Rhodolirium
''Rhodolirium'' is a small South American genus in the tribe Hippeastreae of the family Amaryllidaceae. Although originally described by Philippi in 1858 it has long remained buried in other taxa, principally ''Hippeastrum'' and more recently '' Rhodophiala''. Only in recent years has it been rehabilitated. Restoring the genus was first proposed by Naranjo & Poggio (2000), and accepted by Ravenna in 2003, although he used the name '' Rhodolirion'', originally used by Baker (1878) in his very broad construction of ''Hippeastrum'' including both ''Rhodophiala'' and "''Rhodolirion''". He also renamed '' Rhodolirium andinum'' as ''Hippeastrum rhodolirion''. Later he elevated ''Rhodolirion'' to the status of subgenus, with ''H. rhodolirion'' (subsequently '' Rhodophiala rhodolirion'') as the type species . Subsequently, the genus has been treated as part of ''Rhodophiala''. Description Flowers single or pluriflor, perigone infundibular (funnel shaped) with elongated floral tube. ...
