The northern Adriatic Sea is transient, most recently flooded between 18,000 to 6,000 years ago following the last glacial maximum, and it will drain again with the onset of the next glacial period. Despite its youth, uniformly shallow depth, and flat sediment floor, it hosts a broad range of bottom-dwelling sea life ecologically resembling communities that have existed in the shallow sea since the Ordovician Period, some 500 million years ago.The northern Adriatic is a natural laboratory in which to test hypotheses concerning the shift from the Paleozoic prevalence of stationary suspension-feeders living on the surface of the sediment and feeding from the overlying waters to, more recently, bottom-dwelling animals living dominantly in or actively seeking temporary refuge within the sediments of the sea floor, regardless of where they feed. Across the northern Adriatic Sea there is an ecological gradient from Paleozoic-style surface-dwelling communities in the east to "modern" communities living almost exclusively within the sediments in the west. Therefore, within the relatively small area of the northern Adriatic, there is an existing gradient similar to the profound ecological change from Paleozoic to more modern marine life.During the early twentieth century, life at the bottom of the Adriatic was systematically sampled from the east to the ...
