SUMMARY:Evolutionary perspectives on maternal investment - from conception

DESCRIPTION:My research focuses on maternal investment\, in the broad huma
 n behavioural ecology sense\, where parental investment is viewed as any i
 nvestment in an offspring which incurs a cost to a parent's ability to inv
 est in other current or future offspring. Thus I take maternal investment 
 to encompass not only investment in individual offspring once they are bor
 n\, but also first the decision as to whether to reproduce\, when to repro
 duce\, and which sex to produce. Here I will present results from three di
 fferent strands of my research dealing with these decisions: first I will 
 consider the factors influencing the decision to continue reproducing\, pr
 esenting results from the first studies to look at the impact of postnatal
  depression on parity progression and interbirth intervals in both women f
 rom WEIRD populations and the forager-horticulturalist Tsimane of Bolivia.
  Next\, I will discuss the impact of extrinsic mortality risk on sex ratio
 s at birth\, presenting evidence for skewed male sex ratios at birth in th
 e Agta hunter-gatherers of the Philippines. Finally\, I will consider fact
 ors influencing postnatal maternal investment with a specific focus on wha
 t might cause variations in mother-infant bonding and long-term mother-off
 spring relationship quality in women in contemporary\, industrialised\, lo
 w fertility contexts.
