We analyzed strontium isotopes in more than 500 samples of shell, bone, and dental enamel from modern and archaeological contexts throughout Mesoamerica. The results correspond closely with expectations based upon the local geology and earlier measurements of geological materials. The results show that isotopic variation is significant across Mesoamerica. Thus strontium isotope ratios in dental enamel, which mark the place of childhood residence, can be used not only to document mobility but also in some cases to determine geographic origin. We present five archaeological case studies to illustrate the anthropological significance and range of applications for this technique: the origins of individuals in the “Oaxaca Barrio” at Teotihuacan, a northern origin for the founder of Copan, a local king at Tikal, the regional origin of two of Palenque's rulers, and individuals of African birth in a colonial cemetery in Campeche.

AbstractDigital proxies of human mobility and physical mixing have been used to monitor viral transmissibility and effectiveness of social distancing interventions in the ongoing COVID-19 pandemic. We developed a new framework that parameterizes disease transmission models with age-specific digital mobility data. By fitting the model to case data in Hong Kong, we were able to accurately track the local effective reproduction number of COVID-19 in near real time (i.e. no longer constrained by the delay of around 9 days between infection and reporting of cases) which is essential for quick assessment of the effectiveness of interventions on reducing transmissibility. Our findings showed that accurate nowcast and forecast of COVID-19 epidemics can be obtained by integrating valid digital proxies of physical mixing into conventional epidemic models.

This study investigated strontium isotopes in the dental enamel of 32 human skeletons from Forte Marechal Luz sambaqui (shellmound), Santa Catarina, Brazil, aiming at identifying local and non-local individuals. The archeological site presents pot sherds in the uppermost archeological layers. Dental enamel was also examined from specimens of terrestrial fauna (87Sr/86Sr = 0. 71046 to 0. 71273) and marine fauna (87Sr/86Sr = 0. 70917). The 87Sr/86Sr isotope ratio for individuals classified as locals ranged from 0. 70905 to 0. 71064 and was closer to the isotope ratio of the seawater than to the ratio of the terrestrial fauna, indicating a strong influence of marine strontium on the inhabitants of this sambaqui. The results indicate the existence of three non-local individuals (87Sr/86Sr = 0. 70761 to 0. 70835), buried in both the level without pottery and the layer with pottery, possibly originated from the Santa Catarina Plateau, close to the municipality of Lages, or from the Curitiba Plateau. The occurrence of a slight difference between the isotope ratios of local individuals buried in the archeological layer without pottery, when compared to those in the layer with pottery, suggests a possible change in dietary patterns between these two moments in the site's occupation
