Brandt's vole, [1] (Lasiopodomys brandtii), also known as the steppe vole, is a species of rodent in the family Cricetidae. It is native to shrublands and grasslands in Russia, Mongolia and northern China. [1]
Brandt's vole is about 15 cm (5.9 in) long with a tail up to 3.5 cm (1.4 in) long. Its ears are small and the short fur is uniform sandy-brown, paler underneath. The tail is entirely brown and there are dense hairs on the hind part of the feet. [4]
Brandt's vole is found in Nei Mongol, Jilin, and Hebei provinces in north-east China, [2] in Mongolia and southern Transbaikalia in Russia. Brandt's vole is commonly found in grassland areas. [5] Its typical habitat is dry steppes and pastures. Its sometimes also found in lakeside meadows and river valleys. [4]
Brandt's vole is a colonial species. Each family establishes a network of burrows with several entrances, long passages, storerooms, and nesting chambers. The voles are active during both the day and night and their behaviour varies at different times of year. [6] They feed on both the underground and aerial parts of plants. Large stores of food are laid up before the winter and the energy intake of the voles seems to be correlated with the length of day. [7] There are four or five broods each year, with each litter consisting of about seven young. Population levels are subject to wide swings. Under unfavourable conditions, this vole can be wiped out of some of the regions in which it is normally found, but when the conditions are right, mass outbreaks can occur. This periodically happens in Mongolia when millions of hectares of pasture are invaded. Under this onslaught, the pastures can become very bare, poor subsoil can be brought to the surface by burrowing activities and coarse weeds can become established, seriously harming the grazing for domestic animals. [4]
When exposed to cold temperatures, voles increase their resting metabolic rate. [8] This increase is caused by increased activity from mitochondria in the vole's brown fat, as more energy is used in nonshivering thermogenesis to generate heat. Nonshivering thermogenesis, decreased serum leptin levels, fat mobilization, and hyperphagia are all associated adaptations that the Brandt’s voles undergoes in cold environments. [9] Hyperphagia leading to increased food intake is highest in colder months, but voles expend so much energy during this period that they weigh less in summer months. [10]
The Pallas's cat, also known as the manul, is a small wild cat with long and dense light grey fur, and rounded ears set low on the sides of the head. Its head-and-body length ranges from 46 to 65 cm with a 21 to 31 cm long bushy tail. It is well camouflaged and adapted to the cold continental climate in its native range, which receives little rainfall and experiences a wide range of temperatures.
Voles are small rodents that are relatives of lemmings and hamsters, but with a stouter body; a longer, hairy tail; a slightly rounder head; smaller eyes and ears; and differently formed molars. They are sometimes known as meadow mice or field mice in North America.
Thermogenesis is the process of heat production in organisms. It occurs in all warm-blooded animals, and also in a few species of thermogenic plants such as the Eastern skunk cabbage, the Voodoo lily, and the giant water lilies of the genus Victoria. The lodgepole pine dwarf mistletoe, Arceuthobium americanum, disperses its seeds explosively through thermogenesis.
The Arvicolinae are a subfamily of rodents that includes the voles, lemmings, and muskrats. They are most closely related to the other subfamilies in the Cricetidae. Some authorities place the subfamily Arvicolinae in the family Muridae along with all other members of the superfamily Muroidea. Some refer to the subfamily as the Microtinae or rank the taxon as a full family, the Arvicolidae.
The Afghan vole is a species of rodent in the family Cricetidae. It is found in south-central Asia.
Lasiopodomys is a genus of rodent in the family Cricetidae. It contains the following species:
The plateau vole is a species of rodent in the family Cricetidae. It was originally listed as Lasiopodomys, but was moved to Neodon in 2012. It is found only in China. Its natural habitat is temperate grassland.
The beach vole or Muskeget vole is a rodent in the family Cricetidae. This close relative of the eastern meadow vole is endemic to the 0.87 km2 Muskeget Island, Massachusetts. Due to its relatively short period of reproductive isolation, there is debate over the beach vole's designation as a subspecies of M. pennsylvanicus.
The narrow-headed vole is a species of rodent in the family Cricetidae. It was previously placed in the genus Microtus, but modern listings either lump this into genus Lasiopodomys or split it out into Stenocranius. It ranges over northern and central Asia.
The wood lemming is a species of rodent in the family Cricetidae. It belongs to the rodent subfamily Arvicolinae, so is a relative of the voles, lemmings, and muskrats. It is found in the taiga biome of China, Estonia, Finland, Mongolia, Norway, Russia, and Sweden.
The upland buzzard is a species of bird of prey in the family Accipitridae. The largest species of the Buteo genus, this buzzard lives in mountainous grassy and rocky areas in areas of Central Asia, northern South Asia and East Asia from Kazakhstan to Korea. The upland buzzard is migratory but typically covers a short distance apparently to avoid snow cover that may hamper prey capture. This species primarily subsists on small mammals but does not shun alternate prey from small to large birds and insects. This little known raptor has a large range, and though generally uncommon, it is not thought to be rare or declining as a species. As a result it is classified as least concern by the IUCN.
The plateau pika, also known as the black-lipped pika, is a species of mammal in the pika family, Ochotonidae.
Microtini is a tribe of voles in the subfamily Arvicolinae.
