Résumé

It has been observed that a year before spreading of the intensive plague epizootic among marmots (Marmota sibirica) there was almost no reproduction in population. At that moment the mean age (4.5 years) in the population has reached its maximum. Old marmots (8 years old and more) died more than other age groups by epizootic. After one year from the epizootic, the percentage of adults (3-5 years old) increased. It has been also observed that male marmots 2 times more perislied than females. On the second year after the epizootic a reproduction process in the population activized and on the 3rd year the percentage of young generation predominated on all other age groups. On the territories of intensive hunting marmots reproduction has been already activized on the second year after the hunt.
