Spalacopus
The coruro (''Spalacopus cyanus'') is a species of rodent in the family Octodontidae. It is the only species in the genus ''Spalacopus''. The species is endemic to central Chile, where it has been found in a wide variety of habitats, from coastal to montane. It is fossorial and lives in colonies. Description Coruros are robust rodents with large heads, short necks and stocky bodies. The fur is short and dark brown, turning blackish on the feet. Their eyes and ears are small and their tails are short and smooth. They are strongly modified for life underground. They have large incisors that curve forward and which are used to loosen soil and gnaw through roots, strong forelimbs for digging and powerful hind limbs for moving soil and kicking it out of the entrance to the burrow. They weigh between . Their molars have reentrant folds that do not meet in the middle. Their tails are scaly and hairless. They can be either black or dark brown. Distribution and habitat Coruros occur al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Octodontidae
Octodontidae is a family of rodents, restricted to southwestern South America. Fourteen species of octodontid are recognised, arranged in seven genera. The best known species is the common degu, ''Octodon degus''. Octodontids are medium-sized rodents, ranging from in body length. They have long, silky, fur, which is typically brownish in color, and often paler on the underside. The name 'octodont' derives from the wear pattern of their teeth, which resembles a figure 8. Most are nocturnal, social, burrowing animals, though the degu is largely diurnal. They are herbivorous, eating tubers, bulbs, and cactuses. Some authors have suggested that the octodontids should be reclassified in the order Lagomorpha, but this has not been supported by further analyses. Older literature includes the tuco-tucos in the family, as the subfamily Ctenomyinae, but these animals are normally now treated as a separate family, Ctenomyidae. There is some evidence that evolution within the family ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Georg Wagler
Johann Georg Wagler (28 March 1800 – 23 August 1832) was a German herpetologist and ornithologist. Wagler was assistant to Johann Baptist von Spix, and gave lectures in zoology at the Ludwig Maximilian University of Munich after it was moved to Munich. He worked on the extensive collections brought back from Brazil by Spix, and published partly together with him books on reptiles from Brazil. Wagler wrote ''Monographia Psittacorum'' (1832), which included the correct naming of the blue macaws. In 1832, Wagler died of an accidental self-inflicted gunshot wound while out collecting in München-Moosach. Life Johann Georg Wagler was a German naturalist and scientist in the 19th century, whose works primarily focused on herpetology and ornithology (Beolens, Watkins & Grayson, 2011). Johan Georg Wagler was born on the 28th of March 1800, in the city of Nuremberg, where the Chancellor of the City Court was Wagler's father (Wagler, 1884). After taking up gymnastics at Nuremberg, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leucocoryne Ixioides
''Leucocoryne'' (glory-of-the-sun) is a genus of bulbous perennials in the family Amaryllidaceae. The foliage of all species is long and narrow and has an onion-like scent. The blue, white or lilac flowers are held in umbels. The entire genus is endemic to the Republic of Chile in South America. Some species are grown in gardens as ornamentals. They require very well-drained soil and do not tolerate freezing temperatures. ''L. purpurea'', with purple flowers, has gained the Royal Horticultural Society’s Award of Garden Merit. Derivation of genus name The generic name ''Leucocoryne'' is a compound of the Greek elements λευκός ( = ''leucos'' ) "white" and κορυνε ( = ''korune'' ) "club" ( in the sense of cudgel or bludgeon ) - in reference to the pale, club-like, sterile anthers of the flowers. Taxonomy Species Species accepted by The Plant List are listed here (49) although some authorities estimate only 15. # '' Leucocoryne alliacea'' Lindl. # '' Leucocoryne an ...

Taxa Named By Juan Ignacio Molina
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1782
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together wi ...

Alophia
''Alophia'' is a small genus of perennial, herbaceous and bulbous plants in the family Iridaceae. The genus comprise five known species that occur from the South-central United States as well as in Mexico, Central America, and parts of South America. The genus is closely related to '' Herbertia'', ''Cypella'' and ''Tigridia'', differentiating from them by some characters of the stamen and the gynoecium. The genus name is derived from the Greek words ''a-'', meaning "without", and ''lophos'', meaning "crest".Peter Goldblatt. 1975Revision of the bulbous Iridaceae of North America Brittonia 27: 373- 385. ; SpeciesRoyal Botanical Gardens, KewWorld Checklist of Monocotyledons: ''Alophia'' Accessed April 16, 2009. * ''Alophia drummondii'' (Graham) R.C.Foster, Contr.

Sisyrinchium
''Sisyrinchium'' is a large genus of annual to perennial flowering plant in the family Iridaceae. Native to the New World, the species are known as blue-eyed grasses and, though not true grasses and in varieties with flower colors other than blue, are monocots. Several species in the eastern United States are threatened or endangered. Description These are not true grasses, but many species have the general appearance of grasses, as they are low-growing plants with long, thin leaves. They often grow on grasslands. Many species resemble irises, to which they are more closely related. Most species grow as perennial plants, from a rhizome, though some are short-lived (e.g. ''Sisyrinchium striatum)'', and some are annuals (e.g. '' Sisyrinchium iridifolium''). The flowers are relatively simple and often grow in clusters. Many species, particularly the South American ones, are not blue, despite the common name. The genus includes species with blue, white, yellow, and purple pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dioscorea Longipes
''Dioscorea'' is a genus of over 600 species of flowering plants in the family Dioscoreaceae, native throughout the tropical and warm temperate regions of the world. The vast majority of the species are tropical, with only a few species extending into temperate climates. It was named by the monk Charles Plumier after the ancient Greek physician and botanist Dioscorides. Description Wild Yam (''Dioscorea'') is a vine that is invasive, deciduous, and herbaceous. This species is native to Asia, though, in the U.S., it is commonly found in Florida. They can grow over in length. Wild yams are an important crop, as they have been used to prevent menstrual cramps, stomach cramps, and general pain for centuries. During the 1950s scientists found that the roots of wild yams contained diosgenin which is a plant-based estrogen; diosgenin is hypothesized to aid in chemical defense against herbivores. This was used to create the first birth control pills during the 60s. In addition, some '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chilean Central Valley
The Central Valley ( es, Valle Central), Intermediate Depression, or Longitudinal Valley is the depression between the Chilean Coastal Range and the Andes Mountains. The Chilean Central Valley extends from the border with Peru to Puerto Montt in southern Chile, with a notable interruption at Norte Chico (27°20'–33°00' S). South of Puerto Montt the valley has a continuation as a series of marine basins up to the isthmus of Ofqui. Some of Chile's most populous cities lie within the valley including Santiago, Temuco, Rancagua, Talca and Chillán. Northern section (18°30'–27°20' S) In northernmost Chile the central valley is made up of the Pampitas, a series of small flats dissected by deep valleys.Börger, p. 40. Immediately south of the Pampitas, in Tarapacá Region and northern of Antofagasta Region, the Central Valley is known as Pampa del Tamarugal.Börger, p. 41.Brüggen, p. 6.

Juan Ignacio Molina
Fr. Juan Ignacio Molina (; (June 24, 1740 – September 12, 1829) was a Chilean Jesuit priest, naturalist, historian, translator, geographer, botanist, ornithologist, and linguist. He is usually referred to as Abate Molina (a form of Abbot Molina), and is also sometimes known by the Italian form of his name, Giovanni Ignazio Molina. He was one of the precursors of the theory of the gradual evolution of species, 44 years before Darwin, who repeatedly quoted him in "The Origin of Species". Biography Early years Molina was born at Guaraculén, a big farm located near Villa Alegre (General Captaincy of Chile), where he lived until he was 5 years old. In the current province of Linares, in the Maule Region of Chile. His parents were Agustín Molina and Francisca González Bruna. From an early age he was attracted to the nature of his environment, and in addition to his school work, he enjoyed observing nature on the family farm, which he visited periodically, alternating with ...
