Chapter 10 - Observational and Experimental Methods for the Estimation of Natality, Mortality and Dispersal

In this chapter are discussed the methods of directly quantifying the various processes that produce population change. The magnitude of these different 'pathways' may also be obtained by the subtraction or integration of census figures in a budget: methods of calculation and of analysis of budgets are discussed in the next chapter, but there is no hard and fast distinction between the contents of the two chapters. As is indicated below, in the appropriate sections, the terms 'natality' and 'dispersal' are used in their widest sense.
