摘要：Correction to: Scientific Reports https://doi.org/10.1038/s41598-021-88073-2, published online 22 April 2021 The original version of this Article contained errors in Table 1 and Table 2. In Table 1, the division lines between Sites (“S1”, “S2” and “S3”) and Age class (“Adults” and “Juveniles”) was not clear. Each Site had to contain the Age class “Adults” and “Mean”, and “Juveniles” and “Mean” values. In Table 2, the division lines between Sites (“S1”, “S2” and “S3”) and Food sources was incorrectly placed. Each Site had to contain five Food sources: “Macroinvertebrates”, “Crayfish”, “Detritus”, “Periphyton” and “Macrophytes”. The original Table 1 and Table 2 and accompanying legends appear below. Table 1 Signal crayfish mean (± SD) stable isotope values of carbon and nitrogen, carapace length (CL), number of sampled individuals between sexes, age classes, and sites in Valla Stream in summer and autumn.
