Model-based estimates of annual survival rate are preferable to observed maximum lifespan statistics for use in comparative life-history studies
D.G. Krementz, J.R. Sauer, J.D. Nichols
1989, Oikos (56) 203-208
Estimates of longevity are available for many animals, and are commonly used in comparative life-history analyses. We suggest that annual survival rate is a more appropriate life history parameter for most comparative life history analyses. Observed maximum lifespans estimate complicated functions of survival and sampling probabilities. Annual survival rate estimates...
