Abstract: Key life history traits and costs of reproductionKey life history traits (e.g., Stearns 1992 ) include: • size at birth • growth rate • age and size at sexual maturity • number, size, and sex ratio of offspring produced • reproductive schedule and age-specifi c reproductive investment • age-specifi c mortality • lifespan. Intrinsic costs of reproduction: Trade-offs between reproductive activity and survival or future reproductive rateReproductive trade-offs fall into two categories: physiological and evolutionary ( Stearns 1989( Stearns , 1992 ; ; Flatt and Schmidt 2009 ).To date, the overwhelming research effort has focused on investigating the mechanisms underlying physiological trade-offs.For a summary of methods used to measure physiological and evolutionary costs of reproduction, see Boxes 11-1 and 11-2 .
