Key Points:
- δ18O and δ13C of C.
pulveratrix and M. yantaiensis snails over last 20 ka were
studied to trace paleoclimate and paleovegetation changes.
- δ18O showed more rainfall during MIS3 and MIS7
stages and an overall 1.5 times stronger seasonality during glacial
than interglacial period.
- δ13C revealed more C4 biomass during
warm/humid MIS3 and MIS7 stages and M. yantaiensis ingested
more C4 than C. pulveratrix .
