Gerp's Mouse Lemur
Gerp's mouse lemur (''Microcebus gerpi'') is a species of mouse lemur known only from the Sahafina Forest in eastern Madagascar, near Mantadia National Park. Its discovery was announced in 2012 by a German and Malagasy research team. The Sahafina Forest had not been studied until 2008 and 2009, when Groupe d'Étude et de Recherche sur les Primates de Madagascar (GERP)—a Malagasy-based research and conservation group for which the lemur is named—inventoried the forest's lemurs. Based on genetic studies, measurements, and photos, the research team confirmed the Gerp's mouse lemur was an undescribed species, distinct from Goodman's mouse lemur, which is found away. Gerp's mouse lemur is significantly larger, weighing on average , compared to Goodman's mouse lemur, which weighs about . Jolly's mouse lemur, which is its closest relative and a neighbor to the south, is comparably larger, but differs in tail length and genetics. Because it is a recently discovered species, li ...

Mouse Lemur
The mouse lemurs are nocturnal lemurs of the genus ''Microcebus''. Like all lemurs, mouse lemurs are native to Madagascar. Mouse lemurs have a combined head, body and tail length of less than , making them the smallest primates (the smallest species being Madame Berthe's mouse lemur); however, their weight fluctuates in response to daylight duration. Lemurs and mouse lemurs were announced by the IUCN as the most endangered of all vertebrates. There were two known mouse lemur species in 1992; by 2016, there were 24. It was estimated that the 24 mouse lemur species evolved from a common ancestor 10 million years ago. Evolution of mouse lemurs is an example for adaptive radiation. Mouse lemurs are omnivorous; their diets are diverse and include insect secretions, arthropods, small vertebrates, gum, fruit, flowers, nectar, and also leaves and buds depending on the season. Mouse lemurs are considered Species complex, cryptic species—with very little morphological differences betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
COII
Cytochrome c oxidase subunit 2, also known as cytochrome c oxidase polypeptide II, is a protein that in humans is encoded by the MT-CO2 gene. Cytochrome c oxidase subunit II, abbreviated COXII, COX2, COII, or MT-CO2, is the second subunit of cytochrome c oxidase. It is also one of the three mitochondrial DNA (mtDNA) encoded subunits (MT-CO1, MT-CO2, MT-CO3) of respiratory complex IV. Structure The ''MT-CO2'' gene is located on the p arm of mitochondrial DNA at position 12 and it spans 683 base pairs. The ''MT-CO2'' gene produces a 25.6 kDa protein composed of 227 amino acids. MT-CO2 is a subunit of the enzyme Cytochrome c oxidase () (Complex IV), an oligomeric enzymatic complex of the mitochondrial respiratory chain involved in the transfer of electrons from cytochrome c to oxygen. In eukaryotes this enzyme complex is located in the mitochondrial inner membrane; in aerobic prokaryotes it is found in the plasma membrane. The enzyme complex consists of 3-4 subunits ...

Reddish-gray Mouse Lemur
The reddish-gray mouse lemur (''Microcebus griseorufus'') also known as the gray-brown mouse lemur or rufous-gray mouse lemur, is a small, solitary-but-social, nocturnal and omnivorous primate from the Western Madagascar in the region around Beza Mahafaly Reserve, north to Lamboharana. Like the other lemur species, the reddish-grey mouse lemur is endemic to Madagascar. They generally live in the drier regions of the island. It is categorized as least concerned in the IUCN Red List. Appearance & Morphology ''Microcebus griseorufus'' has a pelage color that is alternating light neutral gray, pale neutral gray, and light pale neutral gray dorsally and ventrally light grayish-white on the anterior two-thirds and bicolored light grayish-white and pale neutral gray on the posterior one-third.

Gray Mouse Lemur
The gray mouse lemur (''Microcebus murinus''), grey mouse lemur or lesser mouse lemur, is a small lemur, a type of strepsirrhine primate, found only on the island of Madagascar. Weighing , it is the largest of the mouse lemurs (genus ''Microcebus''), a group that includes the smallest primates in the world. The species is named for its mouse-like size and coloration and is known locally (in Malagasy) as ''tsidy'', ''koitsiky'', ''titilivaha'', ''pondiky'', and ''vakiandry''. The gray mouse lemur and all other mouse lemurs are considered cryptic species, as they are nearly indistinguishable from each other by appearance. For this reason, the gray mouse lemur was considered the only mouse lemur species for decades until more recent studies began to distinguish between the species. Like all mouse lemurs, this species is nocturnal and arboreal. It is very active, and though it forages alone, groups of males and females form sleeping groups and share tree holes during the day.

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.

Down Hair
Fur is a thick growth of hair that covers the skin of mammals. It consists of a combination of oily guard hair on top and thick underfur beneath. The guard hair keeps moisture from reaching the skin; the underfur acts as an insulating blanket that keeps the animal warm. The fur of mammals has many uses: protection, sensory purposes, waterproofing, and camouflaging, with the primary usage being thermoregulation. The types of hair include * ''definitive'', which may be shed after reaching a certain length; * ''vibrissae'', which are sensory hairs and are most commonly whiskers; * ''pelage'', which consists of guard hairs, under-fur, and awn hair; * '' spines'', which are a type of stiff guard hair used for defense in, for example, porcupines; * ''bristles'', which are long hairs usually used in visual signals, such as the mane of a lion; * ''velli'', often called "down fur", which insulates newborn mammals; and * ''wool'', which is long, soft, and often curly.
