Fig. 6From: Trophic niche separation of two non-spinose planktonic foraminifers Neogloboquadrina dutertrei and Pulleniatina obliquiloculataTrophic position (TPGlu/phe) of two non-spinose planktonic foraminiferal species (Neogloboquadrina dutertrei and Pulleniatina obliquiloculata) along four depth intervals in Suruga Bay, Japan. Error bars indicate the propagation error (potential uncertainly) in TPGlu/Phe calculated in Eq. (5)Back to article page
