Tree Demography Throughout the Tree Life Cycle
Demographic studies and comparative methods have been the basis of a number of ecological studies of plant populations. The demographic consequences of the life cycle of plants have been analyzed with matrix population models. The matrix model was first developed as an age-structured model to describe the dynamics of human populations (Leslie 1945). Later, a size- or stage-structured matrix model was used to analyze insect populations (Lefkovitch 1965). Werner and Caswell (1977) applied these two types of matrix models to plant populations and reported that the size-structured model had higher predictability in plant population dynamics than the age-structured matrix model. Recently size- or stage-structured matrix population models have become common and effective tools for the analysis of plant populations (Caswell 1989; Silvertown and Lovett Doust 1993).
