|New Aug 2005||E-patterns for age-structured animals
based on E-triangles for the 21st century.
If I assume that fertility (m) and adult survival (Sa) are constant, then the mean age of reproducing females at the stable age distribution (Ā) is given by the following equation and the E-pattern for any age-structured species is easily calculated (Mollet and Cailliet 2003; Appendix, pdf). Because the elasticity ratio of adult survival to juvenile survival is given by E(Sa)/E(Sj) = (Ā/α) - 1, it is easy to predict the E(Sa)/E(Sj) ratio using contour plots giving z = E(Sa)/E(Sj) for x = Sa/λ1, y = α, and using ω/α as an additional parameter.
