Determinants of offspring sex in kangaroos: a test of multiple hypotheses

Pauline Toni, David Forsyth & Marco Festa-Bianchet
When the fitness costs and benefits of sons and daughters differ, offspring sex ratio manipulation could be an important reproductive tactic. We explored the effects of environment and maternal caring ability on offspring sex to test four adaptive sex ratio modification hypotheses: the Extrinsic Modification (EMH), Carrying Capacity (CCH), Trivers-Willard (TWH) and Cost-of-Reproduction (CRH) hypotheses. The EMH and CCH propose that environmental conditions shape offspring sex ratios, directly or in interaction with maternal condition. The...
