Asian badgers occupy a diverse range of habitats. They are found in deciduous, coniferous and mixed forests, as well as mountainous regions, steppes, semi-deserts, and tundra. In forested areas they often dig burrows on the south-facing slopes of ravines, where the snow melts earlier. They prefer areas with well-drained soil. In steppe regions they often occupy gullies. They may burrow in the banks of coastal lakes, as well as near the bottom of sand dunes. They always stay near a water source. In the Caucasus Mountains, they range vertically from sea level to the alpine meadows. (Heptner and Naumov, 1967; Long and Killingley, 1983; Neal and Cheeseman, 1996; Ognev, 1962)
Asian badgers have a stocky, somewhat wedge-shaped body. Their limbs are short, with strong elongated claws (22 to 26 mm) that are well-adapted for digging. The average size and mass of Asian badgers varies regionally. Those found in Siberia are larger than those from the far-Eastern part of the range. Their mass also varies throughout the year, peaking in the fall before hibernation. Males are generally larger, but there is variation in the degree of sexual dimorphism between different populations. (Abramov and Puzachenko, 2005; Long and Killingley, 1983; Neal and Cheeseman, 1996; Wilson and Mittermeier, 2009)
The pelage of Asian badgers is dense and coarse. They are generally grayish-silver with a white face and dark brown or black stripes running over each eye. They exhibit a range of regional pelage coloration. Specimens from Mongolia have a relatively lighter coat, while those from the Amur region are particularly dark in color. In addition, mountain inhabitants are almost always darker than those of the plains. (Heptner and Naumov, 1967; Long and Killingley, 1983; Wilson and Mittermeier, 2009)
Asian badgers can mate year-round and fertilization can occur at any time, but cubs are generally only born between mid-January and mid-March. This is achieved through delayed implantation. (Long and Killingley, 1983; Neal and Cheeseman, 1996)
Badgers of the genus Meles give birth once per year, usually between mid-January and mid-March. Mating occurs primarily in the spring. Mating and fertilization may occur throughout the year, but implantation is delayed. There is no data available specific to . (Long and Killingley, 1983; Neal and Cheeseman, 1996)
Badgers of genus Meles show alloparental behavior, where related individuals help raise the young. These relatives may chase the young into the den when they are threatened, or chase away predators. There is no data available for , specifically. (Neal and Cheeseman, 1996)
There is no data available on the lifespan of Meles meles, a close relative, may reach 15 years in the wild; however, it is fairly unusual for individuals to exceed 10 years. The oldest known captive M. meles was 19 1/2 years. (Neal and Cheeseman, 1996)in the wild or in captivity.
Asian badgers are primarily nocturnal. They can be fairly gregarious, living in communal setts (underground burrows) with multiple tunnels and entrances. In areas of limited food availability, the badgers are often solitary. (Heptner and Naumov, 1967; Wilson and Mittermeier, 2009)
Asian badgers often hibernate in family groups, adults share dens with cubs born during the previous year. Yearlings and older single badgers occupy individual dens. (Ognev, 1962)
There is little data available for (Ognev, 1962); however, it is most active within approximately 400 to 500 m of its den.
Badgers of the genus Meles have a relatively high count of rod to cone cells. In addition, they have a tapetum which reflects light back through the retina. These features aid in night vision. The eyes of Meles badgers are relatively small for nocturnal mammals. This indicates that eyesight may be of less importance to the animal than other senses. Meles badgers have an extremely well developed sense of smell. Scroll bones in the nasal cavity provide a large surface area for sensory epithelia. (Neal and Cheeseman, 1996)
Asian badgers are omnivorous and consume a wide variety of foods, including earthworms, insects, mammals, reptiles, birds, frogs, mollusks, berries, pine nuts, and other plant material. Regional badger diet is based largely on availability. Throughout much of its range, earthworms (Lumbricus terrestris) are the most common food source. Insects make up the majority of the Asian badger's diet in more arid regions, such as Mongolia. A population on Bol’shoi Chukhtinskii Island in Russia may subsist largely on pine nuts. They have also been known to prey on young livestock. (Heptner and Naumov, 1967; Long and Killingley, 1983; Murdoch and Buyandelger, 2010; Neal and Cheeseman, 1996; Ognev, 1962; Zagainova and Markov, 2011)
Members of genus Meles are commonly parasitized by fleas (Paraceras melis), lice (Trichodectes melis), and ticks (Ixodes), and to a lesser degree, mites. No specific information is available for . (Neal and Cheeseman, 1996)
There is evidence of Asian badgers preying upon livestock, calves and foals. They are also attracted to grapes in vineyards, and may damage fences to access them. (Ognev, 1962)

in deserts low (less than 30 cm per year) and unpredictable rainfall results in landscapes dominated by plants and animals adapted to aridity. Vegetation is typically sparse, though spectacular blooms may occur following rain. Deserts can be cold or warm and daily temperates typically fluctuate. In dune areas vegetation is also sparse and conditions are dry. This is because sand does not hold water well so little is available to plants. In dunes near seas and oceans this is compounded by the influence of salt in the air and soil. Salt limits the ability of plants to take up water through their roots.
animals that use metabolically generated heat to regulate body temperature independently of ambient temperature. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a (now extinct) synapsid ancestor; the fossil record does not distinguish these possibilities. Convergent in birds.
