Stable isotopes in marsupials: reconstruction of environmental change in Australia

该项目将建立有袋动物骨骼稳定同位素分析在重建过去环境中的应用，这是推进澳大利亚史前史的一个关键领域。在大陆尺度上，它将建立骨骼中的稳定同位素（C、O、N）与环境因素（如植物分布、湿度、温度）之间的关系；在地方尺度上，稳定同位素与土著土地管理之间的关系。该项目将提供从南澳大利亚沿海地区到艾尔湖盆地的样带的晚第四纪环境重建，并探索具有长化石记录的地点的方法局限性。

This project will establish the application of stable isotope analysis of marsupial bones for the reconstruction of past environments, a key area to advance Australian prehistory. On a continental scale, it will establish the relationship between stable isotopes (C, O, N) in bones and environmental factors (e.g., plant distribution, humidity, temperature); on a local scale, the relationship between stable isotopes and aboriginal land management. The project will provide a late Quaternary environmental reconstruction along a transect from the coastal regions in South Australia into the Lake Eyre Basin and explore the methodological limitations at sites with long fossil records.
