What it does
Base on the nitrogen isotopic composition between two amino acids (glutamic acid and phenylalanine), the result shoes that P. obliquiloculata is omnivorous with herbivorous dependence, food source maybe contents more phytoplankton than zooplankton. P. obliquiloculata has ability to sexual reproduction, reproductive cycles have characterized by lunar periodicity, also seasonal changes, the peak breeding period is approximately from autumn to spring, around each full moon. P. obliquiloculata calcification has strong positive correlation with temperature, ocean warming may increase P. obliquiloculata calcification.
