title: Parasite communities and genetic structure of non-native pumpkinseed,<i>Lepomis gibbosus</i>, in different Black Sea drainages of Ukraine
abstract: In recent years, pumpkinseed Lepomis gibbosus (Actinopterygii: Centrarchidae) have spread intensively to many parts of Europe, including Ukraine. In this study, we (1) assess intra-population genetic variability in five widely-spaced Ukrainian pumpkinseed populations and compare their population genetic structure with other European populations and (2) provide a comprehensive survey of pumpkinseed parasites across the region. Discriminant analysis of principal components and F ST analyses based
