Tarucas XV
The taruca (''Hippocamelus antisensis''), also known as the Peruvian guemal, north Andean deer, north Andean huemul, northern huemul or northern guemal, is a mid sized deer species that inhabits the high regions of the Andes mountains in South America. The common name taruca means "deer" in both the Quechua and Aymara languages. The taruca is closely related to the southern guemal (''H. bisulcus''), the only other member of the ''Hippocamelus'' genus. Description The taruca is a medium-sized deer with a heavy body. It measures from head to rump, with an tail, and stands tall at the shoulder. Adults weigh between . As with most deer, males are significantly larger than females. It has sandy brown fur over most of its body, with white patches on the underside of its head, neck, tail, and genital region, and on the inner surface of its fore-legs. While females often have a dark brown area on the forehead, facial markings are much clearer in the males. The exact patterns vary bet ...

Alcide Dessalines D’Orbigny
Alcide Charles Victor Marie Dessalines d'Orbigny (6 September 1802 – 30 June 1857) was a French naturalist who made major contributions in many areas, including zoology (including malacology), palaeontology, geology, archaeology and anthropology. D'Orbigny was born in Couëron (Loire-Atlantique), the son of a ship's physician and amateur naturalist. The family moved to La Rochelle in 1820, where his interest in natural history was developed while studying the marine fauna and especially the microscopic creatures that he named "foraminiferans". In Paris he became a disciple of the geologist Pierre Louis Antoine Cordier (1777–1861) and Georges Cuvier. All his life, he would follow the theory of Cuvier and stay opposed to Lamarckism. South American era D'Orbigny travelled on a mission for the Paris Museum, in South America between 1826 and 1833. He visited Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Argentina, Paraguay, and Brazil, and returned to France with an enorm ...

Glacial Lake
A glacial lake is a body of water with origins from glacier activity. They are formed when a glacier erodes the land and then melts, filling the depression created by the glacier. Formation Near the end of the last glacial period, roughly 10,000 years ago, glaciers began to retreat. A retreating glacier often left behind large deposits of ice in hollows between drumlins or hills. As the ice age ended, these melted to create lakes. These lakes are often surrounded by drumlins, along with other evidence of the glacier such as moraines, eskers and erosional features such as glacial striations, striations and chatter marks. These lakes are clearly visible in aerial photos of landforms in regions that were glaciated during the last ice age. The formation and characteristics of glacial lakes vary between location and can be classified into glacial erosion lake, ice-blocked lake, moraine-dammed lake, other glacial lake, supraglacial lake, and subglacial lake. Glacial lakes and chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mammals Of Chile
A mammal () is a vertebrate animal of the class Mammalia (). Mammals are characterised by the presence of milk-producing mammary glands for feeding their young, a broad neocortex region of the brain, fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which their ancestors diverged in the Carboniferous Period over 300 million years ago. Around 6,640 extant species of mammals have been described and divided into 27 orders. The study of mammals is called mammalogy. The largest orders of mammals, by number of species, are the rodents, bats, and eulipotyphlans (including hedgehogs, moles and shrews). The next three are the primates (including humans, monkeys and lemurs), the even-toed ungulates (including pigs, camels, and whales), and the Carnivora (including cats, dogs, and seals). Mammals are the only living members of Synapsida; this clade, together with Sauropsida (reptiles and birds), constitutes the larg ...

Capreolinae
The Capreolinae, Odocoileinae, or the New World deer are a subfamily of deer. Alternatively, they are known as the telemetacarpal deer, due to their bone structure being different from the plesiometacarpal deer subfamily Cervinae. The telemetacarpal deer maintain their distal lateral metacarpals, while the plesiometacarpal deer maintain only their proximal lateral metacarpals. The Capreolinae are believed to have originated in the Middle Miocene, between 7.7 and 11.5 million years ago, in Central Asia. Although this subfamily is called New World deer in English, it includes reindeer, moose, and roe deer, all of which live in Eurasia in the Old World. Classification The following extant genera and species are recognized:Alvarez D. (2007) * Tribe Capreolini ** Genus '' Capreolus'' *** Western roe deer (''C. capreolus'') *** Eastern roe deer (''C. pygargus'') **Genus '' Hydropotes'' *** Water deer (''H. inermis'') * Tribe Alceini **Genus ''Alces'' *** Moose or Eurasian elk (' ...

Potato
The potato () is a starchy tuberous vegetable native to the Americas that is consumed as a staple food in many parts of the world. Potatoes are underground stem tubers of the plant ''Solanum tuberosum'', a perennial in the nightshade family Solanaceae. Wild potato species can be found from the southern United States to southern Chile. Genetic studies show that the cultivated potato has a single origin, in the area of present-day southern Peru and extreme northwestern Bolivia. Potatoes were domesticated there about 7,000–10,000 years ago from a species in the '' S. brevicaule'' complex. Many varieties of the potato are cultivated in the Andes region of South America, where the species is indigenous. The Spanish introduced potatoes to Europe in the second half of the 16th century from the Americas. They are a staple food in many parts of the world and an integral part of much of the world's food supply. Following millennia of selective breeding, there are now over 5 ...

Barley
Barley (), a member of the grass family, is a major cereal grain grown in temperate climates globally. It was one of the first cultivated grains; it was domesticated in the Fertile Crescent around 9000 BC, giving it nonshattering spikelets and making it much easier to harvest. Its use then spread throughout Eurasia by 2000 BC. Barley prefers relatively low temperatures and well-drained soil to grow. It is relatively tolerant of drought and soil salinity, but is less winter-hardy than wheat or rye. In 2023, barley was fourth among grains in quantity produced, 146 million tonnes, behind maize, rice, and wheat. Globally, 70% of barley production is used as animal feed, while 30% is used as a source of fermentable material for beer, or further distilled into whisky, and as a component of various foods. It is used in soups and stews and in barley bread of various cultures. Barley grains are commonly made into malt using a traditional and ancient method of preparatio ...

Alfalfa
Alfalfa () (''Medicago sativa''), also called lucerne, is a perennial plant, perennial flowering plant in the legume family Fabaceae. It is cultivated as an important forage crop in many countries around the world. It is used for grazing, hay, and silage, as well as a green manure and cover crop. The name alfalfa is used in North America. The name lucerne is more commonly used in the United Kingdom, South Africa, Australia, and New Zealand. The plant superficially resembles clover (a cousin in the same family), especially while young, when glossary of leaf morphology#trifoliate, trifoliate leaves comprising round leaflet (botany), leaflets predominate. Later in maturity, leaflets are elongated. It has raceme, clusters of small purple flowers followed by fruits spiralled in two to three turns containing 10–20 seeds. Alfalfa is native to warmer temperate climates. It has been cultivated as livestock fodder since at least the era of the Ancient Greece, ancient Greeks and Ancient R ...

Lycopodiopsida
Lycopodiopsida is a class of vascular plants also known as lycopsids, lycopods, or lycophytes. Members of the class are also called clubmosses, firmosses, spikemosses and quillworts. They have dichotomously branching stems bearing simple leaves called microphylls and reproduce by means of spores borne in sporangia on the sides of the stems at the bases of the leaves. Although living species are small, during the Carboniferous, extinct tree-like forms ( Lepidodendrales) formed huge forests that dominated the landscape and contributed to coal deposits. The nomenclature and classification of plants with microphylls varies substantially among authors. A consensus classification for extant (living) species was produced in 2016 by the Pteridophyte Phylogeny Group (PPG I), which places them all in the class Lycopodiopsida, which includes the classes Isoetopsida and Selaginellopsida used in other systems. (See Table 2.) Alternative classification systems have used ranks from di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Valeriana
''Valeriana'' is a genus of flowering plants in the family Caprifoliaceae, members of which may be commonly known as valerians. It contains many species, including the garden valerian, ''Valeriana officinalis''. ''Valeriana'' has centers of diversity in Eurasia and South America (especially in the Andes), and is represented by native species on all continents except Antarctica. Some species have been introduced to parts of the world outside their native range, including '' Valeriana rubra'' in the western United States and '' Valeriana macrosiphon'' in Western Australia. Taxonomy The genus was named by Carl Linnaeus after the Roman emperor Publius Licinius Valerianus who was said to use the plant as medicine. The emperor's personal name comes from '' Valeria'' and the Latin verb ''valeo'' which means "to be strong". 32 previously recognized genera, including ''Centranthus'', ''Fedia'', and ''Plectritis'', are now considered synonyms of ''Valeriana''. Species in the form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
