abstract：:Immune defence is hypothesized to be a trait that bears significant fitness costs as well as benefits in that mounting a defence depreciates the value of other life-history traits. Thus the cost of mounting an immune response could affect the evolution of both the immune system and correlated life history traits. In t...
