- Abstract
A model is considered that describes the interaction of predators and prey in a certain area. Moreover, the population of the prey does not leave the site, and the population of predators migrates from the site with an insufficient amount of food resources. The presence or absence of a population of predators in an area is determined by the value of a function that makes sense for the food attractiveness of the area for the population of predators. The model under study is a system of three differential equations, two of which describe the dynamics of the numbers of predators and prey, and one describes the dynamics of the food attractiveness of the site. The task of preserving the species structure of the biological community of the site is solved by the removal of individuals. The species structure of a biocommunity is understood as the set of species and types of interactions between them. A model of the periodic process of the external effect, which preserves the species structure of the biological community, is presented. A numerical method is developed and a program is created that implements the constructed model. The results of testing the program are presented. [ABSTRACT FROM AUTHOR]
