EFFECT OF FEEDING ON THE REPRODUCTION RATE OF ALACTAGULUS PYGMAEUS
Magomedov M.R.D.
The number of Alactagulus pygmaeus females participating in reproduction considerably varies; their proportion was for adults (older than 1 year) from 12,5 to 97,3 percent, while for the young, from 0 to 60 percent. The feeding factor is the most important in regulating the reproduction of A. pygmaeus. Feeding in the pre-hibernation period determines the fatness and condition of the specimens after the hibernation which is directly related with the intensity of the spring reproduction of the population. The feeding in the summer period, specifically their energy level (kJ per 1 specimen per day) determine the reproduction success of the second, summer-autumn period of reproduction. Seasonal feeding variations due to the plant phenology can cause mass migrations of animals which disturb the regular pattern of their spring and summer reproduction.
