深海底栖有孔虫对甲藻的响应 在船上对模拟的泥沙事件进行了评估 通过使用透射电子显微镜进行缩影， 有机碳、腺苷核苷酸、ETS分析 以及现场观察。迅速激活 有孔虫的新陈代谢被检测到 在ETS活性和AMP明显下降的情况下构建 上演一场大戏。基于这种生理觉醒反应， 食物是通过伪足活动收集起来并被摄入的 数量很大。饲喂后三天，品质上乘 在消化液泡中发现了食物，导致了 个体有机碳含量提高89%。 在接下来的六天里，这种食物被转化为 转化为生物量，因为脂质和其他储备化合物 积攒起来的。10天后，含有降解的消化液泡 只有一件事。个体生物量的最终转变 与最初的人口相比是16.9%。
The response of deep-sea benthic foraminifera to a simulated sedimentation event was assessed in a shipboard microcosm by using transmission electron microscopy, organic carbon, adenosine nucleotide, ETS assays and live observations. A rapid activation of foraminiferal metabolism was detected with an incrca e in ETS activity and a distinct decrease in AMP to build up A TP. Based on this phy iological-awakening reaction, food was gathered by pseudopodia] activity and ingested in high quantities. Three days after feeding, high quality food was found in the digestion vacuoles leading to an increase of 89% in individual organic carbon contents. During the following six days, this food was converted into biomass as lipids and other reserve compounds were built up. After ten days, digestion vacuoles contained degraded matter onJy. The final shift in individual biomass was 16.9% in comparison to the initial population.
