Estimating Time‐Varying Survival of Arthropod Life Stages from Population Density

A new technique for calculating survival rates decomposes the density versus time curve for each life stage to obtain the rate individuals are entering and the rate they are leaving that stage. The survival rate is then estimated by a comparison of the rate they leave one stage with the rate they enter the next. The analysis of a hypothetical set of data indicates that the technique can handle relatively imprecise data when at least seven nonzero population estimates are available for each life stage per generation.
