Investigations at the Royal Naval Hospital Cemetery (C. 1763–1834) in English Harbour, Antigua

Tamara L. Varney, Christopher K. Waters, Reginald Murphy

Over two decades of research have focused on reconstructing the lived experiences of individuals who were interred in the cemetery associated with the Royal British Naval Hospital at English Harbour, Antigua, WI (c. 1800). Sporadic salvage excavations have resulted in the disinterment …

Childhood Lead Exposure in North Atlantic Fisheries: Concentration and Isotopic Analyses of Tooth Enamel From 18th to 19th Century Fishing Communities

Tricia Jessica Anne Munkittrick, Amy B. Scott, Tamara L. Varney, Vaughan Grimes

ABSTRACT Objectives This bioarcheological study explored the extent and sources of childhood lead (Pb) exposure in contexts where environmental sources were not anthropogenically enriched. Materials and Methods Sampled Pb concentrations and isotope ratios in the tooth enamel (2nd molars) of 46 individuals …

Ancient Plasmodium genomes shed light on the history of human malaria

Megan Michel, Eirini Skourtanioti, Federica Pierini, Evelyn K. Guevara et autres

Abstract Malaria-causing protozoa of the genus Plasmodium have exerted one of the strongest selective pressures on the human genome, and resistance alleles provide biomolecular footprints that outline the historical reach of these species1. Nevertheless, debate persists over when and how malaria parasites …

Teaching Virtual Forensic Anthropology Labs: Methods and Reflections

J Ross, Clarence Surette, Kathleen Whitaker, Tamara L. Varney

Development of virtual labs for Forensic Anthropology was complicated by the notion that the skeleton cannot be learned without physical manipulation. This was addressed by using free programs to teach using 3D models of bone. Successes and shortcomings are discussed based on …

Insights into biogenic and diagenetic lead exposure in experimentally altered modern and archaeological bone: Synchrotron radiation X-ray fluorescence imaging

Rachel Simpson, Tamara L. Varney, I. Coulthard, Treena Swanston et autres

Bones represent a valuable biological archive of environmental lead (Pb) exposure for modern and archaeological populations. Synchrotron radiation X-ray fluorescence imaging (SR-XFI) generates maps of Pb in bone on a microstructural scale, potentially providing insights into an individual's history of Pb exposure …

Historical overview and new directions in bioarchaeological trace element analysis: a review

Rachel Simpson, David M. L. Cooper, Treena Swanston, I. Coulthard et autres

Given their strong affinity for the skeleton, trace elements are often stored in bones and teeth long term. Diet, geography, health, disease, social status, activity, and occupation are some factors which may cause differential exposure to, and uptake of, trace elements, theoretically …

Investigating Past Lead Exposure in Bioarchaeological Remains with Synchrotron X-ray Fluorescence and Absorption Spectroscopy

Rachel Simpson, Tamara L. Varney, Treena Swanston, I. Coulthard et autres

Bioarchaeology, the sub-discipline of archaeology concentrating on human remains, involves the study of skeletal tissues to make inferences about lifeways in the past. Trace metals such as lead (Pb...

Franklin expedition lead exposure: New insights from high resolution confocal x-ray fluorescence imaging of skeletal microstructure

Treena Swanston, Tamara L. Varney, Madalena S. Kozachuk, Sanjukta Choudhury et autres

In the summer of 1845, under the command of Sir John Franklin, 128 officers and men aboard Royal Navy ships HMS Erebus and HMS Terror sailed into Lancaster Sound and entered the waters of Arctic North America. The goal of this expedition …
