Stable Isotopes in Feces: Proxies for Past and Present Climate, Diet, and Environment
Session ID#: 82141
Session Description:
Both modern and ancient feces archive considerable information about past and present animals and humans and the environments in which they lived. Scientists across several disciplines have recently been using stable isotopes in feces to investigate diet, ecology, behavior, environment and climate in modern, ancient, and even paleontological settings. Although there is general agreement that isotopic records from feces are valuable, there is nonetheless a lack of consensus on what exactly these records measure. In this session, we will address current applications and interpretations of stable isotope data in feces and bring together scientists from diverse backgrounds to foster interdisciplinary exchange. We welcome experimental and observational studies that present methodological developments and applications of isotopes in feces from modern ecologists, archaeologists, paleoclimatologists, and paleoecologists.
