Unformatted text preview: trouble! We might not have info on temporal variability Insights from sensitivity analysis (next) carry over to stochastic case Sensitivity & Elasticity Sensitivity: absolute rate of change of 1 with respect to absolute change in a matrix element Elasticity: relative rate of change of 1 with respect to relative change in a matrix element 1 ij ij S a = 1 1 1 1 1 1 1 ij ij ij ij ij ij ij a a E S a a a = = = Sensitivity & Elasticity of vital rates 1 1 k s s ij r ij i j k a S S r = = = 1 1 k s s ij k r ij i j ij k a r E E a r = = = Sensitivity in management For each potential mgmt action Define its effect on demography (e.g. reduce mortality of adults) Estimate cost per unit effort Use sensitivity or elasticity to find improvement in lambda per unit cost...
