Cooperative breeders adjust offspring sex ratios to produce helpful helpers

Cooperative breeders adjust offspring sex ratios to produce helpful helpers

Whether birds and mammals adaptively adjust their offspring sex ratio in response to their environment is much debated. A source of confusion is that different studies show different patterns, with sex ratio adjustment appearing to occur in some cases but not others. The extent to which this reflect...
