Plant Demography and Ecological Theory

Abstract

The meanings of 'theory' in ecology are examined and illustrated with six examples from plant ecology. The application of demographic theory to plants (and other modular organisms) depends on recognition of two levels of populational organisation - the genet (N) and the modular unit of structure (η). Examples are given to illustrate the theory that a plant is a population of parts that are born and die and the ways in which such theory can be applied to field studies. /// Вначение "теории" в экологии было проанализировано и иллюстрировано шестыо примерами из экологии растений. Приложение демографической тео-рии к растениям и друтим дифференцированным организмам зависит от раз-личения двух уровней популяционной организации - частоты генотипов (N) и модулярной единицы структуры (K). Приведены примеры, иллюстрируюцие положение о том, что растение - популяция частей, которые рождаются и отмирают и способы приложения таких теорий к полевьм исследованиям.
