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 prehistoric times, 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.

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 and 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 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 as Vulnerable by the IUCN Red List The Int ...

Sicista Betulina
The northern birch mouse (''Sicista betulina'') is a small rodent about 5 to 8 cm long (without the tail), weighing 5 to 13 g. It lives in northern Europe and Asia in forest and marsh zones. It hibernates in burrows. It eats shoots, grains, berries, and sometimes insects. Description The northern birch mouse is a small mouse with a relatively long tail. The adult head and body length is with a tail of . Adults vary in weight between . The upper parts are yellowish-grey with a brown sheen and the underparts are a pale greyish-yellow. A black stripe runs along the spine from the head to the base of the tail. Its voice is a high-pitched whistle. Distribution and habitat The northern birch mouse occurs in Scandinavia, Central and Eastern Europe, and Northern Asia. Its main range extends from the Baltic region, Poland and the Czech Republic eastwards as far as Lake Baikal in Siberia, and from the Arctic Circle southwards to the Carpathians.

Southern Birch Mouse
The southern birch mouse (''Sicista subtilis'') is a species of birch mouse in the family Sminthidae. It is native to southern Russia, Kazakhstan, and potentially northern Mongolia and China. Taxonomy The Hungarian birch mouse (''S. trizona'') and Nordmann's birch mouse (''S. loriger'') were previously thought to be subspecies representing isolated western populations of ''S. subtilis'', but phylogenetic and anatomical evidence supports them being distinct species. A 2018 study detected a distinct, previously unknown genetic lineage of ''S. subtilis'' in the North Caucasus. Description The most prominent characteristic of the southern birch mouse is the dark stripe down the center of the back, which is bordered by two narrow bright stripes on both sides. From head to rump it measures from 56 to 72 mm, with a tail from 110 to 130% of the main body length. The background fur color is gray-brown. Ecology The southern birch mouse is pronouncedly a steppe dweller. It mak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sicista Armenica
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 Mam ...
