“…Comparison of the malacological results was challenging as some regional publications (Marković et al, 2018) mixed the concept of spatially and temporally well-delineated biogeographical and Quarternary malacological units manifested as ecoregion mosaics (Olson et al 2001;Giakoumi et al, 2013) with that of zones (Gauthier and Wiken, 2003).
