Sažetak
Several episodes of mass mortalities, affecting populations of corals and other sessile invertebrates, have been recorded over the past 20 years in the eastern part of the Adriatic Sea. The coralligenous community, one of the most diverse in the Mediterranean Sea where suspension feeders are dominant, has been also strongly affected by these events. Current hypotheses about the causes of mass mortality events mostly focus on their relationship with the occurrence of distinctive climatic anomalies during the late summer and early fall, when the thermocline shifted to deeper areas, to more than 40 m depth. Their occurrence and characteristics differed among regions and years and were usually related to the local hydrological conditions. The species affected were mostly long-lived sessile epibenthic invertebrates, such as sponges, anthozoans, bivalves, bryozoans and ascidians. During the two large mass mortality events in 2003 and 2012 in the Adriatic Sea, sea temperatures reached up to 6°C above the average with prolonged water column stability during late summer, and affected approximately 30 marine species down to 40 m depth. The main goal of this study is to provide a comprehensive report on the impact of the mass mortality events by providing data on the species affected, the intensity of the impact, the depth range, and the timing of the event for three study areas in the eastern Adriatic Sea. According to the data obtained, the sites surveyed in the northern part of the Adriatic Sea were the least affected, while the sites in the central and southern Adriatic displayed the highest impact.
