text: Theoretical ecology was greatly influenced by C. Elton’s Animal Ecology (1927), in which the problem of studying the organization (structure) of communities was formulated, the regularities of the relations between the numbers of organisms at different trophic levels (pyramid of numbers) were described, the concept of the ecological niche, proposed earlier by the American zoologist J. Grinnell (1917), was clarified, and attention was focused on variations in the size of populations.
