Cabrera's Vole
Cabrera's vole (''Microtus cabrerae'') is a species of vole native to Spain and Portugal. It is named for Ángel Cabrera, a mammalogist then working at the Museo Nacional de Ciencias Naturales in Madrid. It is the only living member of the subgenus ''Iberomys'', although two fossil species are also known, including ''M. brecciensis'', the likely direct ancestor of the living species. Description Cabrera's vole is one of the largest voles in the genus ''Microtus'', with a body length of and a tail in length. Adults weigh between , up to five times more than other voles native to Spain and Portugal. They have long, thick fur which is brownish olive over most of the body and yellowish in colour on the underparts. The guard hairs are particularly long, reaching as far as out from the body, greater than that in any other ''Microtus'' species. Internally, the caecum is longer than that in most other voles, relative to body size, a feature that may be related to its specialised diet. ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker Richard Lydekker (; 25 July 1849 – 16 April 1915) was an English naturalist, geologist and writer of numerous books on natural history. Biography Richard Lydekker was born at Tavistock Square in London. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vole
Voles are small rodents that are relatives of lemmings and hamsters, but with a stouter body; a longer, hairy tail; a slightly rounder head; smaller eyes and ears; and differently formed molars (high-crowned with angular cusps instead of low-crowned with rounded cusps). They are sometimes known as meadow mice or field mice in North America. Vole species form the subfamily Arvicolinae with the lemmings and the muskrats. There are approximately 155 different vole species. Description Voles are small rodents that grow to , depending on the species. Females can have five to ten litters per year, though with an average lifespan of three months and requiring one month to adulthood, two litters is the norm. Gestation lasts for three weeks and the young voles reach sexual maturity in a month. As a result of this biological exponential growth, vole populations can grow very large within a short time. A mating pair can produce a hundred more voles in a year. Voles outwardly resemble s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ángel Cabrera (naturalist)
Ángel Cabrera (19 February 1879 – 8 July 1960) was a Spanish zoologist. He was born in Madrid and studied at the Universidad Central, Madrid (now part of the Universidad Complutense de Madrid). He worked the National Museum of Natural Sciences from 1902, going on several collecting expeditions to Morocco. In 1907, he proposed that the Iberian wolf was a separate subspecies, which he named ''Canis lupus signatus''. In 1925 Cabrera went to Argentina and remained there for the rest of his life. He was head of the Department of Vertebrate Paleontology at the Museo de La Plata, and made collecting trips to Patagonia and Catamarca. In Patagonia he discovered the first Jurassic dinosaur of South America; he thus began a series of discoveries in this region, one of the richest in dinosaur remains. He supervised the doctoral work of some of the first palaeontologists of South America, including Mathilde Dolgopol de Sáez Mathilde Dolgopol de Sáez (6 March 1901 – 29 ...

Museo Nacional De Ciencias Naturales
The National Museum of Natural Sciences ( es, Museo Nacional de Ciencias Naturales) is the national museum of natural history of Spain. It is situated in the center of Madrid, by the Paseo de la Castellana. It is managed by the Spanish National Research Council (CSIC). History The museum traces back its origin to the ', created in 1771 by Charles III. The ''gabinete'' was refounded as ''Real Museo de Historia Natural'' in 1815. It changed names until its current denomination, received in 1913. The museum originally hosted a collection donated by a Spanish merchant, Pedro F. Dávila. In 1867, some facilities were separated to give birth to other museums (Archeology, Botanic Garden, Zoologic Garden). In 1987 the museum was restructured and enlarged with funds from two smaller museums. Collection Some of the more relevant components of the museum collections are: * A ''Megatherium'' brought from Argentina in 1789. * A ''Diplodocus'' donated by Andrew Carnegie to Alfonso XIII of ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Guard Hair
Guard hair or overhair is the outer layer of hair of most mammals, which overlay the fur. Guard hairs are long and coarse and protect the rest of the pelage (fur) from abrasion and frequently from moisture. They are visible on the surface of the fur and usually lend a characteristic contour and colour pattern. Underneath the contour hair is the short, dense, fine down. There are three types of guard hair: awns, bristles, and spines.G. A. Feldhamer, J. F. Merritt, C. Krajewski, J. L. Rachlow, K. M. Stewart. ''Mammalogy: Adaptation, Diversity, Ecology.

Caecum
The cecum or caecum is a pouch within the peritoneum that is considered to be the beginning of the large intestine. It is typically located on the right side of the body (the same side of the body as the appendix, to which it is joined). The word cecum (, plural ceca ) stems from the Latin '' caecus'' meaning blind. It receives chyme from the ileum, and connects to the ascending colon of the large intestine. It is separated from the ileum by the ileocecal valve (ICV) or Bauhin's valve. It is also separated from the colon by the cecocolic junction. While the cecum is usually intraperitoneal, the ascending colon is retroperitoneal. In herbivores, the cecum stores food material where bacteria are able to break down the cellulose. In humans, the cecum is involved in absorption of salts and electrolytes and lubricates the solid waste that passes into the large intestine. Structure Development The cecum and appendix are formed by the enlargement of the postarterial segment of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Portugal
Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population. Portugal is the oldest continuously existing nation state on the Iberian Peninsula and one of the oldest in Europe, its territory having been continuously settled, invaded and fought over since prehistoric times. It was inhabited by pre-Celtic and Celtic peoples who had contact with Phoenicians and Ancient Greek traders, it was ruled by the Ro ...

Pyrenees
The Pyrenees (; es, Pirineos ; french: Pyrénées ; ca, Pirineu ; eu, Pirinioak ; oc, Pirenèus ; an, Pirineus) is a mountain range straddling the border of France and Spain. It extends nearly from its union with the Cantabrian Mountains to Cap de Creus on the Mediterranean Sea, Mediterranean coast. It reaches a maximum altitude of at the peak of Aneto. For the most part, the main crest forms a divide between Spain and France, with the microstate of Andorra sandwiched in between. Historically, the Crown of Aragon and the Kingdom of Navarre extended on both sides of the mountain range. Etymology In Greek mythology, Pyrene (mythology), Pyrene is a princess who eponym, gave her name to the Pyrenees. The Greek historiography, Greek historian Herodotus says Pyrene is the name of a town in Celts, Celtic Europe. According to Silius Italicus, she was the virgin daughter of Bebryx, a king in Narbonensis, Mediterranean Gaul by whom the hero Hercules was given hospitality during his ...

Iron Age
The Iron Age is the final epoch of the three-age division of the prehistory and protohistory of humanity. It was preceded by the Stone Age (Paleolithic, Mesolithic, Neolithic) and the Bronze Age (Chalcolithic). The concept has been mostly applied to Iron Age Europe and the Ancient Near East, but also, by analogy, to other parts of the Old World. The duration of the Iron Age varies depending on the region under consideration. It is defined by archaeological convention. The "Iron Age" begins locally when the production of iron or steel has advanced to the point where iron tools and weapons replace their bronze equivalents in common use. In the Ancient Near East, this transition took place in the wake of the Bronze Age collapse, in the 12th century BC. The technology soon spread throughout the Mediterranean Basin region and to South Asia (Iron Age in India) between the 12th and 11th century BC. Its further spread to Central Asia, Eastern Europe, and Central Europe is somewhat dela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
