P = mc1/mb1 - mc2/mb2 (1)

were mc1-the number of current-year-born animals according to 1995 data

mb1 the numbers of adult individuals according 1995 data

mc2-the number of current-year-born animals according to 1996 data

mb2 the numbers of adult individuals according 1996 data

N = [ n2 - n1 / nc] 100% (2)

were n1 - the number of reproduced families according to 1995 data

n2 - the number of reproduced families according to 1996 data

nc - the total number of families wich does not change during yhe experimental

R = mc2/n2 - mc1/n1 (3)

were mc1-the number of current-year-born animals according to 1995 data

n1 - the number of reproduced families according to 1995 data

mc2-the number of current-year-born animals according to 1996 data

n2 - the number of reproduced families according to 1996 data

Dependence of a change in the avarage number of current-year-born animals per one adult individual in a dem on removal of different intensivity.

Dependence of a change in the avarage number of current-year-born animals in reproduced families in a dem on removal of different intensivity.

Fig.4

Dependence of the variation coefficient of the number of current-year-born animals in reproduced families in a dem on removal with different untensivity

Variation coefficient of number of current-year-born animals in a reprodused families -S- was calculated in the usual way.
