Abstract
- Why do some species exhibit apparently suboptimal combinations of life history traits? In a comparative study of lizard species, Reedy et al. test the idea that variation in the trade-off between fecundity and survival can be explained by sexual conflict. Their results show that degree of sexual conflict alone cannot explain this variation, and they found a positive correlation between trade-off optimality and the size of males relative to females. These findings suggest a more complicated picture of the fecundity-survival trade-off, possibly involving a third, unknown source of selective pressure.<br /> (© 2019 The Author(s).
