This work shows the potential for applying three-dimensional biometry to studying cell growth in larger benthic foraminifera. The volume of each test chamber was measured from the three-dimensional model obtained by means of computed tomography. Analyses of cell growth based on the sequence of chamber volumes revealed constant and significant oscillations for all investigated specimens, characterized by periods of approximately 15, 30, 90, and 360 days. Possible explanations for these periods are connected to tides, lunar cycles, and seasonality. The potential to record environmental oscillations or fluctuations during the lifetime of larger foraminifera is pivotal for reconstructing short-term paleoenvironmental variations or for gaining insight into the influence of tides or tidal current on the shallow-water benthic fauna in both recent and fossil environments.

较大有孔虫的生长振荡

这项工作显示了应用三维生物测量学研究大型底栖有孔虫细胞生长的潜力。从通过计算机断层扫描获得的三维模型测量每个测试室的体积。基于腔室体积序列的细胞生长分析揭示了所有研究样本的恒定且显着的振荡，其特征在于大约 15、30、90 和 360 天的周期。这些时期的可能解释与潮汐、月球周期和季节性有关。
