Stable Isotope Analysis of Pleistocene Proboscideans from Afar (Ethiopia) and the Dietary and Ecological Contexts of Palaeoloxodon
The timing, cause, and magnitude of mammalian extinctions during the African Middle Pleistocene remain largely unresolved. The demise of Elephas/Palaeoloxodon recki, a lineage that had a great geographic and temporal span, represents a particularly enigmatic case of megafaunal extinction. Previous studies of Early Pleistocene fossil material have proposed that this lineage was a strict C4-grazer, with its dietary specialization causing its extinc…
Simulating the formation of herbivore tooth death assemblages to improve expectations for paleoenvironmental reconstruction from intra-tooth isotopic analysis
Large herbivore δ 18 O as a proxy for aridity in the South African winter and year-round rainfall zone
This study explores patterning in δ 18 O values of tooth enamel in contemporary African herbivores from mainly C 3 -dominated ecosystems. Evapotranspiration causes plants to lose H 2 16 O to a greater extent than H 2 18 O, leaving leaves enriched in 18 O. In eastern Africa, ES species (evaporation-sensitive species: those obtaining water from food) tend to have more positive δ 18 O enamel values than EI species (evaporation-insensitive species: t…
Carnivore stable isotopes as environmental integrators in southern African winter rainfall ecosystems
Diversity in Socioecological Niches in the Andes (Disenia): An Isotope-Based Project
This new project studies the diversity of socioecological niches across the agropastoral transition in the Andes, utilising a multi-isotope approach to track human territories and allocate subsistence tasks. During the agropastoral period, we discriminate different diachronic niches with varying extents of maize farming and altitudinal mobility
Ecosystem engineering in the Quaternary of the West Coast of South Africa
Despite advances in our understanding of the geographic and temporal scope of the Paleolithic record, we know remarkably little about the evolutionary and ecological consequences of changes in human behavior. Recent inquiries suggest that human evolution reflects a long history of interconnections between the behavior of humans and their surrounding ecosystems (e.g., niche construction). Developing expectations to identify such phenomena is remar…
