Algerian Mouse
The Algerian mouse (''Mus spretus''), also known as the western Mediterranean mouse, is a wild species of mouse closely related to the house mouse, native to open habitats around the western Mediterranean. Description The Algerian mouse closely resembles the house mouse in appearance, and can be most easily distinguished from that species by its shorter tail. It has brownish fur over most of the body, with distinct white or buff underparts. It ranges from in head-body length with a 5.9- to 7.3-cm tail and a body weight of . Distribution and habitat The Algerian mouse inhabits south-western Europe and the western Mediterranean coast of Africa. It is found throughout mainland Portugal, and in all but the most northerly parts of Spain. Its range extends east of the Pyrenees into southern France, where it is found in south-eastern regions around Toulouse and up the Rhone valley to Valence. It is also found throughout the Balearic Islands. In Africa, it is found in the Maghreb r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Mouse
The house mouse (''Mus musculus'') is a small mammal of the order Rodentia, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus '' Mus''. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the semi-tame populations near human activity. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002. Characteristics House mice have an adult body length (nose to base of tail) of and a tail length of . The weight is typically . In the wild they vary in color from grey and light brown to black (individual hairs are actually agouti coloured), but domesticated fancy mice and laboratory mice ar ...

Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. The time interval of a gestation is called the '' gestation period''. In obstetrics, ''gestational age'' refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. Mammals In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). Humans In humans, pregnancy can be defined clinically or biochemically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonadotropin (hCG) levels ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1883
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 with Sauropsida ...

Rodents Of Europe
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose inciso ...

Neolithic
The Neolithic period, or New Stone Age, is an Old World archaeological period and the final division of the Stone Age. It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. It began about 12,000 years ago when farming appeared in the Epipalaeolithic Near East, and later in other parts of the world. The Neolithic lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BC), marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In other places the Neolithic followed the Mesolithic (Middle Stone Age) and then lasted until later. In Ancient Egypt, the Neolithic lasted until the Protodynastic period, 3150 BC.Karin Sowada and Peter Grave. Egypt in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cypriot Mouse
The Cypriot mouse (''Mus cypriacus'') is a species of mouse endemic to Cyprus. Its primary habitat seems to be the vineyards and fields of the Troödos Mountains region. The mouse was recognized as a new species in 2004 by Thomas Cucchi, a research fellow at the University of Durham. It was formally described in 2006,12 October 2006, in ''Zootaxa''. The Cypriot mouse has characteristics that distinguish it from other European mice: bigger ears, eyes and teeth; DNA tests confirmed that it was a distinct species. It is native to Cyprus. "All other endemic mammals of Mediterranean islands died out following the arrival of man, with the exception of two species of shrew. The new mouse of Cyprus is the only endemic rodent still alive, and as such can be considered as a living fossil," said Cucchi. Originally, Cucchi wanted to call it ''Mus Aphrodite'', as Cyprus is the birthplace of Aphrodite according to Greek mythology A major branch of classical mythology, Greek mythology i ...

Steppe Mouse
The steppe mouse or mound-building mouse (''Mus spicilegus'') is a species of rodent in the family Muridae. It is found in grassland and other open areas in Austria, Bosnia and Herzegovina, Bulgaria, Croatia, Czech Republic, Hungary, North Macedonia, Romania, Serbia and Montenegro, Slovakia, Slovenia, and Ukraine. Taxonomy ''Mus spicilegus'' ranges from Austria to Southern Ukraine and Greece. Two subspecies are recognised, ''M. s. spicilegus'', the nominate subspecies occupying most of the range, and ''M. s. adriaticus'', an isolated sub-population on the Adriatic coast. It is one of four species of mice in the ''Mus'' subgenus with a western Palearctic distribution, the others being the Macedonian mouse (''Mus macedonicus'') (Balkans to Israel and Iran), the Algerian mouse (''Mus spretus'') (Southern France, Iberian Peninsula, Balearic Islands, Morocco to Tunisia) and the Cypriot mouse (Mus cypriacus) .

Macedonian Mouse
The Macedonian mouse (''Mus macedonicus'') is a species of rodent in the family Muridae and order Rodentia. This rodent lives in the area from eastern Georgia and western Bulgaria to Israel. It is considered part of a Paleoarctic group along with three other species: the house mouse, steppe mouse, and Algerian mouse. Description The Macedonian mouse is a small rodent, weighing . Fur color is variable across its range; in a study of numerous specimens in Turkey, Macedonian mice were found to have back colors ranging from dark brown to pale light brown to dark-reddish brown. There is a distinct line of demarcation along the flanks that separates top and bottom coloration. The bottom coloration ranged from whitish grey, pure white, yellowish white, and reddish white. The ears have tiny white hairs. This rodent has a tail that is dark brown on top and lighter on bottom. The bottoms of the Macedonian mouse's feet are bare while the tops of their feet have white hairs. Macedeo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral
A feral () animal or plant is one that lives in the wild but is descended from domesticated individuals. As with an introduced species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases, contributed to extinction of indigenous species. The removal of feral species is a major focus of island restoration. Animals A feral animal is one that has escaped from a domestic or captive status and is living more or less as a wild animal, or one that is descended from such animals. Other definitions include animals that have changed from being domesticated to being wild, natural, or untamed. Some common examples of animals with feral populations are horses, dogs, goats, cats, rabbits, camels, and pigs. Zoologists generally exclude from the feral category animals that were genuinely wild before they escaped from captivity: neither lions escaped from a zoo nor the white-tailed eagles re-introduced to the UK are regarded as fera ...

Mus (genus)
The genus ''Mus'' or typical mice refers to a specific genus of muroid rodents, all typically called Mouse, mice (the adjective "muroid" comes from the word "Muroidea", which is a large superfamily of rodents, including mice, rats, voles, hamsters, gerbils, and many other relatives). They are the only members of the Tribe (biology), tribe Murini. However, the term mouse can also be applied to species outside of this genus. Subgenera, species, and subspecies '' The following is a list of ''Mus'' subgenera, species, and subspecies: *''Coelomys'' **''Mus crociduroides'' (Sumatran shrewlike mouse) **''Mus mayori'' (Mayor's mouse) **''Mus pahari'' (Gairdner's shrewmouse) **''Mus vulcani'' (volcano mouse) *''Mus (Mus), Mus'' **''Mus booduga'' (Little Indian field mouse) **''Mus caroli'' (Ryukyu mouse) **''Mus cervicolor'' (Fawn-colored mouse) ***''Mus cervicolor cervicolor'' ***''Mus cervicolor popaeus'' **''Mus cookii'' (Cook's mouse) **''Mus cypriacus'' (Cyprus mouse) **''Mus fam ...

Vitamin K
Vitamin K refers to structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation (K from ''Koagulation'', German for "coagulation") or for controlling binding of calcium in bones and other tissues. The complete synthesis involves final modification of these so-called "Gla proteins" by the enzyme gamma-glutamyl carboxylase that uses vitamin K as a cofactor. Vitamin K is used in the liver as the intermediate VKH2 to deprotonate a glutamate residue and then is reprocessed into vitamin K through a vitamin K oxide intermediate. The presence of uncarboxylated proteins indicates a vitamin K deficiency. Carboxylation allows them to bind (chelate) calcium ions, which they cannot do otherwise. Without vitamin K, blood coagulation is seriously impaired, and uncontrolled bleeding occurs. Research suggests that deficiency of v ...
