(A) Distribution of all registered records in the National Malacology Reference Database accounting for freshwater mollusc species from 1982–2018. (B) Updated distribution of Pseudosuccinea columella from Cuba. Positive sites were plotted with different points representing 11-year time intervals to account for historical and newly recorded data. Resistant populations are named in the map, consistently with previous published works. The year of first record of resistant populations is also indicated. (C) Number of records of P. columella per type of habitat. (Laboratory of Malacology, IPK).
