Contrary to previous studies, we document dramatic dietary and floral changes with interglacial warming.
Furthermore, oxygen isotopes in fossil mammal teeth demonstrate increased aridity and decreased relative seasonality with interglacial warming.
We first compare carbon isotope values and evaluate the hypothesis that dietary niches, inferred from the mean and breadth of carbon isotope values, did not change with interglacial warming.
These geographically similar terrestrial localities provide the rare opportunity to examine how mammals altered their diets in response to interglacial warming during the late Pliocene to early Pleistocene.
We currently are in the Holocene interglacial warming period.
Then they lugged them back to Ohio to begin independent study (IS) projects on characterizing the change in sea levels during the last interglacial warming period.
All of these studies suggest that mammalian responses to interglacial warming were generally minor.
These data are in agreement with 50,000-year-old pollen records that indicate drying with interglacial warming in Florida [32].
Lastly, the effects of interglacial warming on mammalian communities and their environments may not have been as profound during the late Pleistocene to the early Holocene, as compared to the late Pliocene to the early Pleistocene.
The aridity index of Levin et al. (2006) was used to test if interglacial warming resulted in increased aridity by comparing the total range of δ18O values between localities.
