Three groups of American scientists claim that soon the Sun should come unusually long period «hibernation» when his activity will fall sharply.
Such conclusion scientists have made, observing sunspots. They are the indicator of the intensity of the light. It appeared that the Sun had completed its 24th cycle (every solar cycle lasts about 11 years), and the number of spots on it rapidly decreases. According to the Director of the National solar Observatory, USA Frank hill, «the current cycle of solar activity may be the last maximum before the Sun „sleep“ for several Read more [...]
Yellow gophers different subspecies differ in terms of puberty. As we pointed out (1955), in South Kazakhstan and Chu valley squirrels participate in reproduction after the first winter hibernation at the age of 11-12 months, and in the northern parts of the range - after the second hibernation. Smaller subspecies are more hasty than larger ones. It should, however, be noted that the number of participants in the semi-mature females breeding ground squirrels from the south-eastern part of the area does not exceed 9.5% (Kydyrbaev, 1959). In males, puberty occurs later, so they are involved in Read more [...]

Periodic seasonal sleep, or "hibernation" is a kind of animal dermis adapt to adverse environmental conditions. Study of the phenomenon of seasonal hibernation occupied many scientists in different countries. In the Soviet Union conducted research NI Kalabukhov colleagues, AM Nikolsky, SY Arbuzov, AD Slonim and others. The result was obtained with respect to a lot of interesting changes in the body for a long time sleeping animals.
Seasonal hibernation of animals is characterized primarily by the numbness, the disappearance of activity. In countries with cold and temperate climates, 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 [...]
Terms of bedding and wake squirrels depend on a variety of reasons - geographical, climatic and landscape (topography, slope exposure in the mountains, etc.).
Sleep long-tailed ground squirrel in the Altai starts in September - October. Sometimes squirrels occur much earlier because of the burning of vegetation on the slopes of the southern exposure. So, in 1948, most of the adult squirrels did not appear on the surface, starting from the second half of August. From hibernation in that area squirrels wake up in late March - mid April. Consequently, the duration of hibernation of ground Read more [...]
