This question has not been studied. We can assume that like other marmots, abrupt changes in abundance there. However, fluctuations in the intensity of reproduction (see "Reproduction"), especially in the lower zone habitat, this Groundhog undoubtedly exist. They are due, probably, drought and low fatness females, which causes a change in the age composition of the population. Natural disasters and disease were observed. The basic factor that reduces the number of marmots Marmot, unordered fishing.
Practical value. Marmot Marmot - a valuable fur. However, the value of the skins Read more [...]
Description. Marmots, including marmot, are among the largest representatives of the squirrel family. Their body fat, clumsy, resting on short, strong legs. The head is large, flat, with a few notable auricles, short neck. From other marmot marmot is easy to distinguish the short-tail, low and very dense fur, as well as uniform sandy-yellow color. The admixture of black hair back is covered brownish or blackish smooth ripples, the gathering at the neck and at the top of the head. Cheeks and sides of the neck svetloryzhevatye. The lower body and legs ocher-yellow color. End of the tail dark Read more [...]
This gopher settles in holes arranged quite primitive. Only during calving in one burrow lives with female offspring, and at other times, each animal has a separate hole, which serves as a protection from adverse weather conditions and predators. Most of the normal timed to the opening, and some shelters are under bushes and rocks, so completely invisible from the outside. On open gravelly slopes emissions of land from small holes. Only in a few cases, they reach a large diameter (2-3 m), but their height does not exceed 25-30 see
Average gopher relatively rare burrows with vertical speed, Read more [...]
Voice gray marmot is most similar to that of marmot. The usual cry (in human form) dvuslozhen and sounds like a high resounding "kupyk-kupyk" audible in the mountains, RP Zimin (1953), at a distance of 500-700 m Expressing displeasure gray marmot emits a high, somewhat nasal sound like the cry of crows. When anger (eg protected) it is similar to a dog growls when shrill screams of pain (like a pig), caressing the person or wanting to get food, animal often quietly cackles "Ko-Ko-Ko-Ko", waving with tail up . With the sudden imminent danger (noting the dog, fox, etc.) makes Read more [...]
Epizootologicheskoei epidemiological significance. Within the Kazakh part of the area median gopher acts as a carrier of several diseases - tularemia, leptospirosis, brucellosis and toxoplasmosis (Galouzeau and Rementsova, 1959).
Abjection tularemia from the body indicates the presence of gophers in Kazakhstan steppe and desert-names foci of tularemia in which the specified rodent mites and desert Rhipicephalus ritSho and Rh. schulzei are the main carriers and transmitters of infection.
This gopher was keeper of Leptospira in southern Kazakhstan.
In the semi-arid zone of a selected Read more [...]

Muskrat - Water animal. Body length - 18-21,5 cm, tail-17-22 cm Weight of live animals - from 300 to 400, the scaly, nearly hairless tail muskrat, rounded at the base, flattened on the sides, in the main part of the tail are small glands that produce fragrant musk consumed perfume industry. Long head animal ends proboscis, eyes small. Hind feet - with flipper. The coat of the animal is thick silky fluff and often quite soft spine, paint the back and sides dark chestnut, casings - silver-white.
Muskrat are found in the floodplains of rivers of Volga, Don and the Urals, from 1929 to 1940, Read more [...]
Gray marmot Pale, but he observed movement: the dispersal of the winter burrow in the summer (at the intersection of macro-and meso), a change of foraging areas, resettlement of adult animals, changes in the number. There are far more non-periodic movements such migrations and displacement due to human activities (Bibikov, 1962).
Resettlement of marmots wintering refuges in the summer is about two weeks to four after their exit from the normal at the end of hibernation. It covers almost all inhabited burrows (female with cubs often remains in the wintering hole), but its range is typically Read more [...]
Data on hibernating marmots marmot is very small (Yanushko, 1951, Petrov, 1960, 1961; Kapitonov and Lobachevsky, 1964) and have not dug any holes with the sleeping animal.
Preparing for hibernation begins essentially with the accumulation of fat, referred to above, and the workpiece nest lining. Harvesting period occurs from mid - late July and continues until hibernation, but there is a very non-intensive. Killing the hole one tuft of grass, animal never went for the second, and went to feed or rest. Only after a long time (hours or more) along the way he seems to be attributed a second Read more [...]
In ex. Virgin territory in marmot found rikketsni Burnet (Karulina, 1961 b). There is speculation that a few centuries ago, when lazybones was widely distributed in the steppes of Europe, there are natural foci of plague (Gromov et al, 1965). In Northern and Central Kazakhstan marmot plague disease were detected.
In the spring of 1959 in the south of the lakes Tselinograd mass mortality water rats (probably from tularemia). In this same period of the lake. Shoindykul neranenyh found two well-fed, the recently dead marmot. The cause of death is the same as that of the rat, as such we will Read more [...]

In the lower zone habitat in the northern slope of the central part of the Kyrgyz range (1200-1300 m above sea level. m) Long- marmot out of the norm after hibernation in mid-March (Kuznetsov, 1948). At this time, still a lot of snow and animals in the first week - and a half little active. At sea level. Most Shirkotiya (lowlands Kalinin district of Kyrgyzstan near the border with Kazakhstan) Woodchucks in 1941 to 25 March was little activity, although it was eating food, as evidenced by their fresh droppings around burrows. March 30, these animals were fed for quite some time in the bush Read more [...]
A characteristic feature in the distribution of long-tailed ground squirrel is busy Slight them land that emerges most clearly in a highly mosaic mountain landscape. He settles micropopulations in areas with relatively gentle slopes that are most often confined to the upper reaches of the rivers. The settlements are often separated by insurmountable obstacles for the animals. Thus, in the upper river. Greater Baskaev summer of 1962 we were able to find large populations of ground squirrels in only two places - in the tract Sursay Taukensay and held a 10-15 km from each other and separated by Read more [...]
Fleas - Small blood-sucking insects, ectoparasites of mammals and birds. Eggs are laid in burrows of animals on the premises - in dry debris, cracks and cracks. Worm-like larvae of free-living, mobile, feed on organic particles. Date for the total transformation of fleas depend on supply, temperature, and humidity. Basic medical importance of fleas - the spread of pathogens transmitted diseases, including the plague. Plague bacteria penetrate the body through regurgitation during bloodsucking fleas or through broken skin of feces infected insects. In addition, fleas infect human endemic (rat) Read more [...]
By catches, tropleny and visual observations in the settlements of the animal registered 17 species of rodents, five - predatory, one insectivore (eared hedgehog), two - birds, some reptiles and invertebrates. The closest relationship to the yellow ground squirrel burrows are animals, arrange them in their holes, - the average ground squirrel (Betpak Dala South Balkhash), small gopher (West Betpak Dala), clawed ground squirrel and a large gerbil (Muyunkum), red- gerbil (Or the left bank) and Tamarisk midday gerbil. Of the four-legged predators - polecat, of birds - Gavel-dancer and less - Little Read more [...]
. Clawed ground squirrels live in burrows with one stroke, deprived of underground connections, like other ground squirrels. However, taking the slopes of the dunes described seekers are often located in separate groups (from 5-15), reminiscent of the settlement of marmots in the highlands.
In Taukum developed krupnobugristye sands, and at the appropriate slope of sand hills there is a group of holes, boundaries are mezhbarhannye slide covered sagebrush-Sole-sound vegetation. Number of burrows in settlements varies, reaching 30-40. Often there are homes, sometimes without any system located. Read more [...]
