Forschungsinteressen
My main research interests lie in the reconstruction of early hominin dietary adaptation, with a focus on the onset and evolution of meat consumption and the position of Plio-Pleistocene hominins in African paleo-food webs based on nitrogen isotopes in tooth enamel. Moreover, I reconstruct Neogene paleolandscapes occupied by early hominins, with a focus on C4-grassland expansion as a result of changing ecosystem patterns such as seasonality, precipitation, temperature, atmospheric pCO2-concentration and (the retreat of) tree-cover. To do this, I rely on extensive fieldwork and geochemical approaches including stable isotopes of carbon, oxygen and nitrogen, as well as clumped isotopes and multi-element analysis in a variety of proxy materials such as fossil tooth enamel and pedogenic carbonates. My focus lies on Miocene to Pleistocene south-east African fossil sites (Karonga Basin in Malawi, Manyara Basin in Tanzania, the Urema Basin in Mozambique, and the Cradle of Humankind in South Africa).
My goal is to recognize the processes that link early hominin (dietary) adaptations to changes in the ecosystem they lived in, to evaluate the onset, evolution and importance of animal resource consumption, and to understand the role of dietary flexibility in the extinction and adaptive radiation of early hominin taxa.
Recently, my
colleagues and I developed a novel oxidation-denitrification method for
analyzing the nitrogen isotopic composition of mineral-bound organic matter in ~5
mg modern and fossil tooth enamel. We established that enamel nitrogen records
the isotopic composition of diet and preserves a trophic signal in both a
feeding experiment and in natural ecosystems (Leichliter et al., 2021, Lüdecke and Leichliter et al., 2022). Moreover, we
demonstrate that nitrogen isotopes in fossil tooth enamel represents a powerful
new paleodietary proxy that could help delineate major dietary transitions in
ancient vertebrate lineages (Leichliter and Lüdecke et al., 2023).
