Stable light isotopes in fauna as environmental proxies in the Southern African winter and year-round rainfall zones
… of environmental and climatic variables on the stable carbon, nitrogen and oxygen isotopic values of wild African fauna from C3 dominated environments. Most previous studies of isotopic ecology in Africa have been carried out in summer rainfall regions. This study focuses on the winter rainfall …

A paleoenvironmental reconstruction of the Elands Bay area using carbon and nitrogen isotopes in tortoise bone
This study explores the utility of stable light isotopes in Chersina angulata (angulate or bowsprit tortoise) bone collagen as a paleoenvironmental proxy, to augment the limited range of proxies preserved in Southern Africa. δ¹³C and δ¹⁵N were measured in 76 archaeological tortoises from Elands Bay …

Radiocarbon reservoir effects in the American bottom flood plain of the Mississippi River and adjacent uplands in southern Illinois
Radiocarbon reservoir effects (RREs) occur when the 14C activity in a system does not maintain equilibrium with atmospheric 14CO2 activity. Within aquatic systems, old (14C-depleted) carbon may dilute the current carbon pool by soil erosion, decomposition of old botanical and fauna remains, and …
