dc.description.abstractThe complex Danube–Black Sea geoecosystem, created by a unique combination of integrated biotopes and biocoenoses related forces and counter-forces in time and space, forms a rich “ichthyosystem”. The equilibrium among the fish species captured in the Danube Delta reveals its structural and functional roles in the connectivity of the Danube and Black Sea. The key role of the delta is evidenced by the fact that 57.26% of the Lower Danube–Danube Delta–North West Black Sea fish species use two or three of the subsystems in terms of habitats. Therefore, this convergence area can be considered to be a dynamic and rich “ichthyosystem”, with three subsystems. All three evolved interdependently, which permits their flexibility and adaptation in an interdependent way. The habitat heterogeneity, native economic and conservation priority fish species of the Lower Danube–Danube Delta–North Western Black Sea have decreased significantly, and there are no indications that this trend will be halted soon. The Danube “sub-ichtyosystem” seems to be more directly affected than the others. The Lower Danube–Danube Delta–North Western Black Sea “ichthyosystem” exhibits a significant level of flexibility, resilience and adaptation over geological time, but has become much more sensitive to environmental perturbations due to the last century of human impact. This “ichthyosystem” is affected by non-native fish species. The study area represents an interdependent ecological net, without which the specific “ichthyosystem” formed over geological time will disappear. The studied ecological net fish fauna is an accurate indicator of various human pressures. The Lower Danube–Danube Delta–North West Black Sea geoecosystem, in which the Danube Delta provides the pivotal habitat element, is the matrix for a unique “ichthyosystem.” However, human impacts decrease its resilience and can induce its extinction.en_UK
