Modelling ecological succession, with particular reference to Markovian models,cets of the latter class of models are discussed, demonstrating that there are far more disadvantages to their use than apparent advantages. However, Markovian models do appear to have predictive ability, and it is also considered that the patterns of probabilities in Markovian matrices may have a r

An analysis of succession along an environmental gradient using data from a lawn,) recognized by numerical classification are correlated with degree of shading, season and differences between years by means of generalized linear model analysis. More of the variance is explained if environmental position is used instead of degree of shading as spatial distribution of a strongly c

Probing time series vegetation data for evidence of succession, The results suggest that the recording period is sufficiently long for trends to be detected. A dominant trend depicts density changes as simple monotone functions of time. Other lesser trends signify cyclic changes of different lengths. The fact that a dominant monotone trend exists is interpreted

Towards the analysis of vegetation succession,nical analysis for this purpose is then made by reference to two applications of the method. The applications deal with characteristics of hydroseral processes and with the dynamic status of an area of lowland tropical rain forest. On the basis of these and other studies the conclusion is drawn that
