| 摘要 | To better understand the dietary evolution and habitat change of pandas, this study analyzed the stable carbon and oxygen isotope compositions of tooth enamel samples from the early Pleistocene pandas Ailuropoda microta and Ailuropoda wulingshanensis and their associated mammals recovered from Yanliang Cave and Longgu Cave in South China. The enamel delta C-13 values indicate that mammals living in these cave areas during the early Pleistocene had C-3-based diets but some individuals consumed small amounts of C-4 grasses. This suggests that C-4 grasses were present in the region during the early Pleistocene, likely in patches of open areas (or savanna woodlands) in a predominantly forested landscape. The delta C-13 and delta O-18 data clearly show niche partitioning among panda, pig, and other animals. The pandas had the lowest enamel-delta C-13 values among all mammals examined, indicating that these early Pleistocene pandas had pure C-3 diets composed of plants growing in the under stories of closed -canopy forests. A pure C-3 diet for these ancient pandas is consistent with an already established dietary niche of bamboo (a C-3 plant) in the early Pleistocene. These ancient pandas also had higher delta O-18 values than all other contemporaneous mammals (except the deer at Longgu Cave), suggesting that they did not drink as much as other large mammals did. The available isotope data suggest that pygmy panda (A. microta) was less ecologically flexible compared to other mammals such as pig, rhino, deer and bovid. The limited ecological flexibility of pygmy panda may have contributed to its demise during climatic fluctuations in the Pleistocene. The reconstructed delta O-18 values of meteoric water in the study areas during the early Pleistocene are lower than the present-day mean annual precipitation delta O-18 values in the region, suggesting a wetter climate or stronger summer monsoon in the early Pleistocene than today.
