Biodemography: Research prospects and directions

The purpose of this opinion report is to outline what I consider to be the most promising areas for future biodemographic research and to suggest ways in which the field can be moved forward. I discuss five major themes: i) biodemography of disability; ii) ecological, developmental, behavioral and evolutionary biodemography; iii) biodemography of sociality; iv) genomic and genetic biodemography; and v) biodemographic modeling and analysis. I consider the last two areas (genomics/genetics; modeling/analysis) as both stand-alone topics and cross-cutting concepts. At the end of the paper I present ideas for charting the future course including strengthening and expanding infrastructure, database and website development, organizing conferences, submitting new training grants, and integrating biodemography into teaching programs.biodemography, frailty, life span, longevity

A Partition Theorem for a Randomly Selected Large Population

We state and prove a proposition on partitioning of a randomly selected large population into stationary and non-stationary populations by using a property of stationary population identity. Applicability of this theorem for practical purposes is summarized at the end.Comment: 7 pages, a new result in population dynamic

Biocultural Consequences of Spanish Contact in the Lambayeque Valley Region of Northern Peru: Internal Enamel Micro-defects as Indicators of Early Life Stress

This study utilizes dental histological methods to analyze enamel micro-defects (Wilson bands) as indicators of early life stress in indigenous Muchik individuals interred at two sites: La Capilla Santa María Magdalena De Eten (CSMME) (n=15) and La Capilla Del Niño Serranito (CNS) (n=15), both located in the Lambayeque region of northern Peru. Individuals interred at CNS date to the Early Colonial Period (A.D. 1533-1620) and individuals interred at CSMME date to the Middle/Late Colonial Period (A.D. 1620-1760). Results reveal a fairly high prevalence of Wilson bands at both sites, with a lower prevalence at CSMME. This indicates that, over time, Muchik individuals may have been able to acclimate to life under Spanish oppression. Stress chronologies suggest that early life stress possibly resulted from inadequate and less than desirable food and/or water available for supplemental feeding during early infancy, especially around the ages of 4 and 5 months
