Recently, increased concentrations of anthropogenic atmospheric CO₂ have caused ocean warming and acidification, leading to swift environmental alterations. In coral reef regions, bleaching and death of symbiotic calcifying organisms have been distressing. Generally, large benthic foraminifers (LBF), a principal symbiotic calcifying organisms in coral reefs, have gained popularity because thermal stress impedes their growth and ecological functions. Nevertheless, due to the complex nature of the shell structure, it is unclear whether indicators (shell volume, density, and size) influence the calcification rate. Micro X-ray computed tomography (MicroCT) has been efficiently used to study these parameters on porcelaneous LBF; however, hyaline LBF remained largely unexplored. In this research, reproducing populations of LBF Calcarina gaudichaudii were grown asexually under six varying temperatures (19 °C–29 °C). They were then determined using MicroCT. Shell weight and volume is reduced under high and low thermal stress with an optimal water temperature of 26 °C. However, the density of the shell was sustained at a continual level. These outcomes indicate that C. gaudichaudii can sustain a continual shell density given circumstances of growth inhibition due to thermal stress.

_{最近，人为大气 CO 2}浓度增加导致海洋变暖和酸化，导致环境迅速改变。在珊瑚礁地区，共生钙化生物的白化和死亡一直令人痛心。一般来说，大型底栖有孔虫 (LBF) 是珊瑚礁中主要的共生钙化生物，由于热应力阻碍了它们的生长和生态功能而受到欢迎。然而，由于壳结构的复杂性，尚不清楚指标（壳体积、密度和大小）是否影响钙化率。显微 X 射线计算机断层扫描 (MicroCT) 已被有效地用于研究瓷质 LBF 的这些参数；然而，透明 LBF 在很大程度上仍未得到探索。在这项研究中，LBF Calcarina gaudhaudii的繁殖种群在六个不同的温度（19°C–29°C）下无性生长。然后使用 MicroCT 确定它们。在最佳水温为 26 °C 的高热应力和低热应力下，外壳重量和体积都会减少。然而，壳的密度保持在一个连续的水平。这些结果表明，在由于热应力导致生长抑制的情况下，C. gaudhaudii可以维持连续的壳密度。
