Malagasy Mountain Mouse
The Malagasy mountain mouse or Koopman's montane voalavo (''Monticolomys koopmani'') is a rodent within the subfamily Nesomyinae of the family Nesomyidae. It is monotypic within the genus ''Monticolomys'', and is closely related to the big-footed mouse ''(Macrotarsomys)''. It is found in the highlands of eastern Madagascar. A small mouse-like rodent, it is dark brown on the upperparts and dark gray below. It has small, rounded, densely haired ears and broad feet with well-developed pads. The long tail lacks a tuft at the tip. The skull is delicate and lacks crests and ridges on its roof. First collected in 1929, the Malagasy mountain mouse was not formally described until 1996, but it is now known to have a broad distribution. Active during the night, it occurs in both montane forest and human-disturbed grasslands and feeds on fruits and seeds. A scansorial animal, it climbs trees but also lives on the ground. Although habitat destruction may pose a threat, it is classified as " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Muséum National D'histoire Naturelle
The French National Museum of Natural History, known in French as the ' (abbreviation MNHN), is the national natural history museum of France and a ' of higher education part of Sorbonne Universities. The main museum, with four galleries, is located in Paris, France, within the Jardin des Plantes on the left bank of the River Seine. It was formally founded in 1793 during the French Revolution, but was begun even earlier in 1635 as the royal garden of medicinal plants. The museum now has 14 sites throughout France.

Voalavo
''Voalavo'' is a genus of rodent in the subfamily Nesomyinae, found only in Madagascar. Two species are known, both of which occur in mountain forest above 1250 m (4100 ft) altitude; the northern voalavo lives in northern Madagascar and eastern voalavo is restricted to a small area in the central part of the island. The genus was discovered in 1994 and formally described in 1998. Within Nesomyinae, it is most closely related to the genus ''Eliurus'', and DNA sequence data suggest that the current definitions of these two genera need to be changed. Species of ''Voalavo'' are small, gray, mouse-like rodents, among the smallest nesomyines. They lack the distinctive tuft of long hairs on the tail that is characteristic of ''Eliurus''. The tail is long and females have six mammae. In ''Voalavo'', there are two glands on the chest (absent in ''Eliurus'') that produce a sweet-smelling musk in breeding males. In the skull, the facial skeleton is long and the braincase is smoo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RBP3
Retinol-binding protein 3, interstitial (RBP3), also known as IRBP is a protein that in humans is encoded by the ''RBP3'' gene. RBP3 orthologs have been identified in most eutherians except tenrecs and armadillos. Function The inter- photoreceptor retinoid-binding protein is a large glycoprotein known to bind retinoids and found primarily in the interphotoreceptor matrix of the retina between the retinal pigment epithelium and the photoreceptor cells. It is thought to transport retinoids between the retinal pigment epithelium and the photoreceptors, a critical role in the visual process. Gene The human IRBP gene is approximately 9.5 kbp in length and consists of four exons separated by three introns. The introns are 1.6-1.9 kbp long. The gene is transcribed by photoreceptor and retinoblastoma cells into an approximately 4.3-kilobase mRNA that is translated and processed into a glycosylated protein of 135,000 Da. Structure The amino acid sequence of human IRBP can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypogeomys

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between org ...

Cytochrome B
Cytochrome b within both molecular and cell biology, is a protein found in the mitochondria of eukaryotic cells. It functions as part of the electron transport chain and is the main subunit of transmembrane cytochrome bc1 and b6f complexes. Function In the mitochondrion of eukaryotes and in aerobic prokaryotes, cytochrome b is a component of respiratory chain complex III () — also known as the bc1 complex or ubiquinol-cytochrome c reductase. In plant chloroplasts and cyanobacteria, there is an analogous protein, cytochrome b6, a component of the plastoquinone-plastocyanin reductase (), also known as the b6f complex. These complexes are involved in electron transport, the pumping of protons to create a proton-motive force ( PMF). This proton gradient is used for the generation of ATP. These complexes play a vital role in cells. Structure Cytochrome b/b6 is an integral membrane protein of approximately 400 amino acid residues that probably has 8 transmembrane segments. ...

DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gerbillinae
Gerbillinae is one of the subfamilies of the rodent family Muridae and includes the gerbils, jirds, and sand rats. Once known as desert rats, the subfamily includes about 110 species of African, Indian, and Asian rodents, including sand rats and jirds, all of which are adapted to arid habitats. Most are primarily active during the day, making them diurnal (but some species, including the common household pet, exhibit crepuscular behavior), and almost all are omnivorous. The gerbil got its name as a diminutive form of "jerboa," an unrelated group of rodents occupying a similar ecological niche. Gerbils are typically between long, including the tail, which makes up about half of their total length. One species, the great gerbil (''Rhombomys opimus''), originally native to Turkmenistan, can grow to more than . The average adult gerbil weighs about . One species, the Mongolian gerbil ('' Meriones unguiculatus''), also known as the ''clawed jird'', is a gentle and hardy anima ...
