Seventy-five years of change: Long-term reorganisation of helminth communities in the rook (Corvus frugilegus) in Ukraine

(Cram, 1927), which became dominant species. This likely reflects species range expansion or niche replacement following the collapse of earlier helminth communities. This study suggests a dynamic system rather than a simple decline and highlights the value of synanthropic species and institutional collections for reconstructing long-term dynamics of host-parasite systems under sustained anthropogenic pressure.
