在近期气候高度多变的情况下，大尺度北方气候和区域尺度亚得里亚海水文气候变化的综合效应显著地反映在亚得里亚海生态系统中。为了阐明这一点，我们建立了两个年际系统：1961 - 2010年期间的海气互联系统和大洋生态系统。在此期间，发生了显着的变化，通过1987-1998年期间，其特点是在亚得里亚海中间层的温度，盐度和氧浓度下降的亚得里亚海的通风较弱的结果。远洋生态系统对这些变化作出了反应。海洋生物群（从浮游生物到中上层鱼类）的大幅波动表明，80年代后期前后的状况有很大不同。通过分析生物参数观察到的不同模式似乎与修改有关的东地中海瞬变（EMT），其影响防止温暖和咸水团入侵亚得里亚海的温盐环流。这些结果提供了证据之间的连接在中东亚得里亚海远洋生态系统和北方半球的气候变化，通过区域大气条件的变化，并强调了北方半球气候变化的重要性，亚得里亚海的物理和生物制度。
In recent highly variable climate, a combined effect of a large-scale northern hemisphere climate and regional-scale Adriatic hydroclimate changes significantly reflected in the Adriatic Sea ecosystem. To clarify this statement we set up in connection two inter-annual systems: the airsea interconnected system and pelagic ecosystems for the period 1961 to 2010. Within this period, significant changes occurred through 1987-1998 period, characterized by a drop of temperature, salinity and oxygen concentration in the middle Adriatic intermediate layer as consequence of a weaker ventilation of the Adriatic Sea. The pelagic ecosystem reacted to these changes. Large fluctuations in marine biota (from plankton to pelagic fish) revealed significantly different regimes before and after the late eighties. Different patterns observed through analyzed biotic parameters seem linked to modification in thermohaline circulation related to the Eastern Mediterranean Transient (EMT), whose effects prevented warmer and saltier water mass intrusions into the Adriatic Sea. These results provide evidence on connections between the shifts in the middle Adriatic pelagic ecosystem and the northern hemisphere climate via changes in regional atmospheric conditions, and highlight the importance of northern hemisphere climate changes for physical and biological regimes of the Adriatic Sea.
