Place of the vitality analysis in population research and nature protection work

Abstract

The basic stages of formation of the population analysis in ecology are considered. The attention to the special place and priorities of the population approach in modern exploratory and nature protection practice is paid. Giving due to the contribution coenopopulation researches, it is necessary to recognise that they do not correspond to requirements of today, and it is necessary to recognise as unique object of the population analysis naturalistic populations. Key problems, their interfering unifications in different biological disciplines are shown. The place and aspects of the vitality analysis as obligatory and basic stage in researches of naturalistic populations are defined. Its sequence is offered at carrying out of the population analysis in ecology. On the basis of perennial researches of the author, the conclusion is drawn that owing to discrepancy of ecological optimums and tolerance ranges to reacting factors at individuals of different vitality, operative autoregulation of populations is carried out. Thus, their prospects are in imperative dependence from vitality composition. The attention to an absolute must of using data about vitality composition and viability of populations is paid at carrying out of nature protection actions. In particular, optimisation of the vitality degraded populations by their artificial recruitment by parent individuals of scarce vitality is recommended.
