Effects of electric current on growth, chlorophyll a content, pulse amplitude modulation response, and new chamber formation of the foraminifera Amphistegina lobifera@en

The electrodeposition of calcium carbonate via low-level electric current has been shown to enhance growth in calcifying organisms, providing a valuable tool for restoration programs. This dataset documents experiments to investigate the effects of low electric current densities on the larger benthic foraminiferal species Amphistegina lobifera. Samples of living foraminifera were collected at Haifa, Shikmona Station, Mediterranean Sea, Israel. The datasets represent two experiments conducted one after the other from April to May 2023, testing the same range of low level electric currents on A. lobifera and measuring different paraments. The first experiment evaluated the effects of electric current on the physiology of its endosymbionts using PAM fluorometry and chlorophyll a content analysis. The second experiment assessed the growth rate through morphological analysis and calcein labeling while also tracking the physiology of the endosymbionts using PAM fluorometry. Positive growth rate and newly formed chambers were recorded […]通过低电平电流实现碳酸钙电沉积的方法已被证实可促进钙化生物的生长，为海洋修复项目提供了极具价值的研究工具。本数据集记录了一系列探究低电流密度对大型底栖有孔虫物种 Amphistegina lobifera 的影响的实验。实验所用活体有孔虫样本采集于以色列地中海海法市西克莫纳站。本数据集包含2023年4月至5月依次开展的两组实验，均针对A. lobifera测试相同范围的低电平电流，并测量不同实验参数。第一组实验采用脉冲振幅调制（Pulse Amplitude Modulation, PAM）荧光分析法与叶绿素a含量检测技术，评估电流对其体内内共生体生理状态的影响。第二组实验通过形态学分析与钙黄绿素（calcein）标记法测定物种生长速率，同时亦采用PAM荧光分析法追踪其内共生体的生理状态。实验记录了阳性生长速率与新形成的房室[…]
