Parasite stress predicts offspring sex ratio. [PDF]

PLoS ONE, 2012
In this study, I predict that the global variation of offspring sex ratio might be influenced in part by the level of parasite stress. From an energetic standpoint, higher gestational costs of producing a male offspring could decrease male births in a ...
