Popis: According to the results of the long-term (1974–2011) monitoring of permanent sample plots at the Institute of Ecology of the Carpathians, National Academy of Sciences of Ukraine, located at the upper border of spruce forests of the Carpathians, patterns of characteristic stages of self-regeneration (regeneration) of the subpopulation structure of Soldanella hungarica Simonk. after severe local damage are generalized. It is found that, under experimental conditions, these point exposures do not cause the general destabilization of population processes. However, they initiate behavioral responses for the mobilization of the population reserve of S. hungarica on nearby areas. The varying role of individual and group effects in these processes is revealed. The conclusion of the decisive importance of the vitality composition for the results of local regeneration of the S. hungarica population is made. It is stated that the self-regeneration of the S. hungarica structure on the experimental plots is a time-consuming process that requires several decades.
