Seasonal modulation of reproductive effort during early pregnancy in humans
(American Journal of Human Biology, 2009-03-03)
Abstract.
Life history theory predicts that early pregnancy presents a relatively low cost, uncontested opportunity for a woman to terminate investment in a current reproductive opportunity if a conceptus is of poor quality ...
Seasonal and circadian variation in salivary testosterone in rural Bolivian men
(American Journal of Human Biology, 2009-02-19)
Abstract.
Testosterone (T) plays a key role in the increase and maintenance of muscle mass and bone density in
adult men. Life history theory predicts that environmental stress may prompt a reallocation of such investments ...
Where the O2 goes to : preservation of human fetal oxygen delivery and consumption at high altitude
(The Journal of Physiology, 2009)
Fetal growth is decreased at high altitude (> 2700 m). We hypothesized that variation in fetal O2
delivery might account for both the altitude effect and the relative preservation of fetal growth in
multigenerational ...
Augmented uterine artery blood flow and oxygen delivery protect andeans from altitude-associated reductions in fetal growth
(Am J Physiol Regul Integr Comp Physiol, 2009-02-20)
Abstract.
The effect of high altitude on reducing birth weight is markedly less in
populations of high- (e.g., Andeans) relative to low-altitude origin
(e.g., Europeans). Uterine artery (UA) blood flow is greater ...
