摘要	Limited studies on proloculus size of foraminifera inhibits its reliable application in palaeoceanographic reconstruction. This study shows that salinity has a significant effect on the proloculus size of shallow water benthic foraminifera Ammonia aomoriensis. Four culture experiments and 13-month long seasonal study from May 2014 to May 2015 in an intertidal flat, Qingdao Bay was conducted on the proloculus size of living A. aomoriensis. The mean proloculus size (MPS) of A. aomoriensis in both the offspring reproduced by culture experiments and the Rose Bengal stained specimens from the field gives a negative correlation with salinity: MPS (mu m) = 65.2737 (+/- 4.3334) - 0.3357 (+/- 0.1468) Salinity (parts per thousand) (Eq. (1),p = 0.0297, r = -0.3908, 24-33 parts per thousand) in cultures; MPS (mu m) = 214.7030 (+/- 20.7783) - 5.4215 (+/- 0.6902) Salinity (parts per thousand) (Eq. (2), p<0.0001, r = -0.6979, 29-31 parts per thousand) in the field. Regression in the case of field study displayed a sharper slope as compared to the laboratory cultures, probably owing to the appearance of both microspheric agamont and megalospheric schizont in A. aomoriensis induced by the fluctuating environment in nature. As a result, salinity could be one of the prime factors responsible for the dimorphism behavior of A. aomoriensis and we suggest that Eq. (1) is more appropriate for optimum condition where megalospheric gamont is exclusively dominant, while Eq. (2) is more appropriate for unstable environment where trimorphism is observed. Thus, the MPS of A. aomoriensis can be used in palaeoenvironmental reconstruction.
