Due to the indelible nature of enamel, bioarchaeologists use linear enamel hypoplasia (LEH) to detect early investments in surviving stress and have identified an association between LEH presence and constraints in growth and maintenance as well as an increased susceptibility to future stress events. This study evaluates heterogenous frailty and susceptibility to death in relation to episodes of early life stress, as reflected by LEH presence, in the Ancestral Pueblo Southwest. This study hypothesizes that LEH presence will be associated with decreased survivorship and an increased likelihood of mortality in both samples.

通过 Pueblo Bonito 和 Hawikku 的线性釉质发育不全评估生活史权衡：对祖先普韦布洛西南地区早期生活压力和生存的生物文化研究

由于牙釉质不可磨灭的性质，生物考古学家使用线性牙釉质发育不全 (LEH) 来检测早期对压力生存的投资，并确定了 LEH 的存在与生长和维持的限制以及对未来压力事件的易感性增加之间的关联。本研究评估了与早期生活压力事件相关的异质性虚弱和死亡易感性，正如 LEH 的存在所反映的那样，在祖先普韦布洛西南部。该研究假设 LEH 的存在将与两个样本中的存活率降低和死亡可能性增加有关。
