Correction to: Niche differentiation among invasive Ponto-Caspian Chelicorophium species (Crustacea, Amphipoda, Corophiidae) by food particle size

A calibration mistake caused systematic error in the microscopic measurements; all filter mesh size values should be divided by a factor of 2.56. As our conclusions were based on the inter- and intraspecific variations of the trait, this systematic error does not influence them in any way. Filter mesh sizes ranged between 2.47 and 7.17 μm in C. curvispinum , between 1.83 and 5.09 μm in C. robustum , and between 1.03 and 2.68 μm in C. sowinskyi . Interspecific differences were estimated correctly as 1.12 μm ( SE = 0.15) between C. curvispinum and C. robustum , and 1.37 μm ( SE = 0.15) between C. robustum and C. sowinskyi . The correct version of Figure 2 and Table 3 are provided in this correction.
