Map of sampling sites where specimens were collected for stable isotope analysis to estimate the trophic niche overlap of topmouth gudgeon (Pseudorasbora parva) and crucian carp (Carassius carassius). Species: Syn = topmouth gudgeon + crucian carp; syn+GC = topmouth gudgeon + crucian carp + gibel carp (C. gibelio). Site details are given in Table 1 with corresponding ID.
