Human mobility on Cancun Island during the Late Postclassic: Intra- and inter-site demographic interactions.

Residential mobility in Prehispanic Mesoamerica is of paramount importance in bioarchaeology to determine the "how, where and why" people established biological, political and economic networks. The goal of this paper is to assess the presence of non-local people on the East Coast of the Yucatan Peninsula during the Late Postclassic (AD 1200-1540), and how they might have been perceived by the local Maya people. We analyze the presence, origin and mortuary distribution of 50 individuals based on their dental and bone 87Sr/86Sr signatures in the "urban" assemblage constituted by the archaeological sites known as El Rey and San Miguelito on Isla Cancun.

Age-at-death standards for Mesoamerican Prehispanic and colonial infant, child, and juvenile skeletons.

This study aims to develop age-at-death standards for Valley of Mexico skeletal collections. Using 159 individuals, with a dental age-at-death between 0 to 15 years, we develop linear and quadratic inverse regression models of age-at-death estimation between dental age and the diaphyseal length of the six long bones. A blind test for both regressions was performed, also a regression developed for a Maya group was carried out.

Dental health and alimentation among the Quintana Roo Mayas: coastal and inland sites of the classic-postclassic periods.

Objectives: The goal of this study is to compare both dental and skeletal stress indicators of the Classic and Postclassic coastal and inland sites of the State of Quintana Roo, Mexico. The hypothesis is that coastal populations will show osteo and dental pathologies characteristic of a primarily marine food source combined with a diet of horticultural resources. This kind of alimentation provides people with less environmental stress and therefore a better health status.

Impact of commercial farming on household reproductive strategies in Calakmul, Campeche, Mexico.

Objectives: The purpose of this study was to determine if commercial agriculture can lead to changes in peasant reproductive strategies in migrant agriculturalists from Calakmul, Campeche, Mexico.

Methods: The reproductive histories of 746 women from Calakmul, Campeche, Mexico were collected. The sample was first divided into women who had reproduced within or outside of Calakmul (RC and RO, respectively) and these were further subdivided into those who lived in households practicing subsistence agriculture and those who turned agriculture into a business (Household Subsistence Agricultural Strategy (HSA) and Household Commercial Agricultural Strategy (HCA), respectively).
