Unveiling the Ongoing Expansion of Bullheads of the Genus Ameiurus (Actinopteri: Siluriformes) in the Dnipro River Basin, Ukraine: New Distributional Records and Genetic Diversity
ABSTRACT Invasive bullheads of the genus Ameiurus are actively expanding across Eastern Europe, yet accurate species identification remains problematic owing to phenotypic plasticity and high intraspecific morphological variability. This study aims to resolve the taxonomic identity, spatial distribution, and invasion d...
