Abstract: (En)
Are the dynamics of arid zone shrub populations best described as event-driven or continuous? This thesis quantified the relative importance of episodic versus continuous processes usin a matrix modelling approach. The main conclusion has been that event-driven and continuous processes each contribute in similar degree to long-term changes in arid shrub populations. this quantification is set within the context of a widely held view that episodic events dominate the demography of arid zone shrubs. Shrub d y range managers and administrators. Much of the change during a manager's working lifetime will be gradual. Therefore a world view that includes gradual change will provide managers with repeated opportunities to acquire knowledge through adaptive lear
