Sminthidae
Sminthidae is a family of mouse-like jumping rodents. They are represented by only one extant genus, '' Sicista'', represented by 19 species found throughout most of Eurasia, from central Europe east to Siberia, and south to southern China. However, they were much more diverse and had a much wider range in prehistory, having multiple genera and being found not only in Eurasia but also throughout North America, where they existed up to the early Pleistocene. They have a well-attested fossil record which dates as far back as the early Oligocene. They were formerly classified as the subfamily Sicistinae in the family Dipodidae alongside the jerboas and jumping mice, but phylogenetic evidence supports all three of these belonging to distinct families, thus leaving only the jerboas in Dipodidae.

Sicista
Birch mice (genus ''Sicista'') are small jumping rodents that resemble mice with long, tufted tails and very long hind legs, allowing for remarkable leaps. They are the only extant members of the family Sminthidae. They are native to Eurasian forests and steppes. All variants possess a long tail of of length and weigh about . Head and body length of and hind foot length of . The animal's skin color is light brown or dark-brown to brownish yellow on the upper side and paler on the underside, but generally brownish. Birch mice have a vast geographic distribution in that they inhabit a wide variety of habitats, from semiarid areas to subalpine meadows. Although they have a diverse region of areas, their molecular and anatomical markers have claimed that Birch mice originated from Central Asia. Birch mice have a systematic of the genus of ''Sicista'', they look at the male reproductive organs and cytogenic data. Species Nineteen species are listed by the American Society of Mamm ...

Nordmann's Birch Mouse
Nordmann's birch mouse (''Sicista loriger'') is a species of birch mouse in the family Sminthidae. It is named after Finnish biologist Alexander von Nordmann. It is native to Eastern Europe, eastern and Southeast Europe, southeastern Europe. Taxonomy It was long thought to be a subspecies of the southern birch mouse (''S. subtilis''), but a 2016 study found sufficient genetic and anatomical divergence for it to be considered its own species. Distribution It is restricted to the western portion of the Pontic–Caspian steppe, where it is known only from a few isolated populations in southern Ukraine, west Belgorod Oblast, Belgorod in Russia, and eastern Romania. In addition, it may potentially be found in Bulgaria and Moldova. Status This species has a fragmented distribution due to its reliance on the largely developed steppe habitat. Populations in these fragmented regions also face ongoing threats from development and agriculture. Due to this, this species is classified ...

Armenian Birch Mouse
The Armenian birch mouse (''Sicista armenica'') is a species of rodent in the family Sminthidae. Description It is a small rodent, like the mouse, the average weight of 10 g and up to 9 cm long, excluding the semi-prehensile tail, which slightly exceeds the length of the body. The body is brown, darker in the upper region. Biology The species shows nocturnal and feeds on seeds, berries and insects. Shifts in the ground with small jumps and can easily climb on the bushes and trees due to its semi-prehensile tail. The nest, oval shaped, is made of plant remains in a shallow hole dug by the animal itself. Distribution and habitat The species is endemic to Armenia, found in mixed forests of coniferous and broadleaf trees in the area upstream of the river Marmarik. Status and conservation The Zoological Society of London, on the basis of evolutionary uniqueness and smallness of the population, considers Armenian birch mouse one of the 100 species of mammal A ma ...

Caucasian Birch Mouse
The Caucasian birch mouse (''Sicista caucasica'') is a species of rodent in the family Sminthidae, that is endemic to Russia. Reports that it occurs in Turkey probably refer to Armenian birch mouse (''Sicista armenica''), from which it can only be reliably distinguished on the basis of karyotype. The Caucasian birch mouse inhabits the Western Montane Caucasus area, land situated between the Black Sea and the Caspian Sea The Caspian Sea is the world's largest inland body of water, described as the List of lakes by area, world's largest lake and usually referred to as a full-fledged sea.

Jerboa
Jerboas () are the members of the family Dipodidae. They are hopping desert rodents found throughout North Africa and Asia. They tend to live in hot deserts. When chased, jerboas can run at up to . Some species are preyed on by little owls (''Athene noctua'') in central Asia. Most species of jerboas have excellent hearing that they use to avoid becoming the prey of nocturnal predators. The typical lifespan of a jerboa is around 2–3 years. Taxonomy Jerboas, as previously defined, were thought to be paraphyletic, with the jumping mice (Zapodidae) and birch mice (Sminthidae) also being classified in the family Dipodidae. However, phylogenetic analysis split all three as distinct families, leaving just the jerboas in Dipodidae and revealing them to be a monophyletic group. This animal has a body length (including the head) of between , with an additional of tail, which is always longer than the full body. Jerboa dental records reveal a slow increase in crown heights, which cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the Order (biology), order Rodentia ( ), which are characterized by a single pair of continuously growing incisors in each of the upper and Mandible, lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for 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/ricochetal (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 Mouse, mice, rats, squirrels, prairie dogs, porcupines, beavers, Cavia, guinea pigs, and hamsters. Once included wi ...
