The paper presents a diagnostic complex for plankton studies using the miniDHC (digital holographic camera). Its capabilities to study the rhythmic processes in plankton ecosystems were demonstrated using the natural testing in Lake Baikal in summer. The results of in situ measurements of plankton to detect the synchronization of collective biological rhythms with medium parameters are presented and interpreted. The most significant rhythms in terms of the correlation of their parameters with medium factors are identified. The study shows that the correlation with water temperature at the mooring site has the greatest significance and reliability. The results are verified with biodiversity data obtained by the traditional mesh method. The experience and results of the study can be used for the construction of a stationary station to monitor the ecological state of the water area through the digitalization of plankton behavior.
本文提出了一种使用 miniDHC（数字全息相机）进行浮游生物研究的诊断综合系统。该系统的能力通过在夏季贝加尔湖的自然测试得到了证明，可用于研究浮游生物生态系统中的节奏性过程。本文介绍并解释了利用原位测量浮游生物来探测集体生物节律与介质参数同步的结果。根据与介质因子参数的相关性，确定了最显著的节律。研究表明，与系泊点水温的相关性具有最大的意义和可靠性。结果通过传统网具法获得的生物多样性数据进行了验证。该研究的经验和结果可用于通过浮游生物行为的数字化来构建一个固定站，以通过数字化监测水域的生态状态。
