Proximate and ultimate explanations of mammalian sex allocation in a marsupial model
Offspring sex ratios in mammals vary in potentially adaptive yet unpredictable ways. An integrative approach that simultaneously examines proximate and ultimate explanations of mammalian sex ratios would greatly advance the field. We examined the importance of maternal glucose and stress hormones for offspring sex (male or female) as mechanisms associated with the Trivers-Willard and the local resource competition hypotheses of sex allocation. We tested this framework in a marsupial mammal, the...[Show more]
