Abstract. Changes in the life strategy during urbanization are discussed, especially those associated with a change in position in the r-K continuum. In newly formed urban populations of various species, the strategy moves towards “more K-” due to a set of changes that reinforce each other. 1) The number of offsprings per breeding attempt falls, but population growth is maintained due to a more significant effect of lengthening the average life expectancy. This brings their demographics closer to that of Homo sapiens. 2) Preference for future reproduction in the best conditions compared to the efforts invested in the reproduction «here and now», for which a directed movement is carried out to search for them, «following» the dynamics of the urban environment. 3) «Urban» individuals make more breeding attempts, «splitting» the realization of their reproductive potential more than «forest» ones. At the same time, «urban» individuals are more plastic, both in terms of variability in the timing and size of the clutch, and in terms of fidelity to the territory, depending on the situation around, on whether the biotope remains unchanged or its disturbances occur. We show the universality of such changes in relation to different urbanizing species, their applicability also to populations that develop other landscapes modified by man.
