Data from: Baby on board: olfactory cues indicate pregnancy and fetal sex in a non-human primate

- 摘要:
- mechanisms of paternity confusion; cues that also advertise fetal sex may additionally facilitate differential sex allocation.

- 摘要:
- Sex allocation theory predicts that simultaneous hermaphrodites evolve to an evolutionary stable resource allocation, whereby any increase

- 摘要:
- matings by females in this species therefore constrain sex allocation through this “sperm-blocking” effect, eliciting a cost to polyandry. Here we explore
