Abstract. Elasticities of [lambda] indicate the influence of demographic parameters on both individual fitness and population growth for a population with density-independent growth. Here we discuss the extension of elasticity analysis to populations with density-dependent demographic parameters and examine the circumstances in which the standard density independent analysis gives useful information for populations that are, in reality, density dependent. In the presence of density dependence the fitness of one strategy depends upon what the rest of the population is doing. Elasticities of fitness must therefore be ...
