“…The species appears to be susceptible to a wide range of parasites in Europe (Ondračková et al ., 2021), though species richness and abundance is still considerably higher in its native range, with over 100 species recorded (Hoffman, 1999). Recently, several North American parasite species infecting pumpkinseed, including myxozoans (Goswami et al ., 2021), monogeneans (Havlátová et al ., 2015; Kvach et al ., 2018; Ondračková et al ., 2021), cestodes (Kvach et al ., 2020) and trematodes (Kvach et al ., 2017; Stoyanov et al ., 2017), have been reported in different European regions. While release from natural enemies, including parasites and pathogens (Keane & Crowley, 2002), is generally reported during the initial stages of a species' introduction, non‐native species often go on to acquire local parasites, although their numbers are usually still lower than those found in native species (Gendron et al ., 2012; Ondračková et al ., 2015).…”
