Abstract

Typical characteristics of the behavioral reactions of the Mediterranean mussel Mytilus galloprovicialis Lam, 1819 in its natural habitat of the Black Sea have been investigated using the originally developed automated biomonitoring complex of the aquatic environment. The valve movements exhibit a pronounced, clear solar diurnal rhythm, with maximum valve opening amplitude at night and minimum in the daytime at ambient natural environmental conditions throughout the year. Two types of valve movements are defined in the diurnal rhythm of the activity of the mussels inhabiting the Black Sea. Mollusks react acutely to abrupt fluctuations in the physical factors of the environment by closing the valves instantly for a short time, which is a manifestation of protective reflexes. The manifestation of stress signs is observed in behavioral reactions to an abnormal acute decrease in water temperature and prolonged exposure to a high water temperature.

黑海自然栖息地地中海贻贝的行为反应特征

摘要

地中海贻贝Mytilus galloprovicialis的行为反应的典型特征已使用最初开发的水生环境自动生物监测复合体对1819年在黑海的自然栖息地的林进行了调查。阀门的运动表现出明显的，清晰的太阳昼夜节律，全年在周围自然环境条件下，夜间的阀门开启幅度最大，白天的阀门开启幅度最小。居住在黑海中的贻贝活动的昼夜节律定义了两种类型的瓣膜运动。软体动物会在短时间内即刻关闭阀门，从而对环境中物理因素的突然变化做出剧烈反应，这是保护性反射的体现。在对水温异常急剧下降和长时间暴露于高水温的行为反应中观察到了压力迹象的表现。
