Sažetak
The shallow carbonate platforms of the central Tethys, exemplified by the Adriatic platform, are particularly expressed to sealevel rise and fall corresponding to the sedimentary sequences of the Paleogene. These cycles, by their repetition, constitute a kind of natural experiment allowing us to test the behaviour of communities in on ecological gradient covering the uephotic zone. In this gradient, the communities of larger K-strategist foraminifera are substituted according to fixed rules: agglutinated conical forms appear first, are gradually replaced by porcelaneous forms, subsequently by nummulitids and assilinids and finally by discocyclinids and "operculinids".Thus, the euphotic zone can be subdivided into 4 depth subzones.
