In a simulation model, the relative advantage of negative versus positive allometry of defense, that is, early versus delayed defensive investment, depends on the forms of the relationships between body size and growth, body size and mortality deterrence, and defense size and mortality deterrence. Positive allometry is favored by strongly sigmoidal growth, a strongly convex body-size/deterrence relationship, and a concave defense-size/deterrence relationship. Rapid early growth, a weakly convex… CONTINUE READING
