Abstract
Among the mechanisms that allow competing species to coexist are resource partitioning and dietary segregation. The current study uses multiple stable isotopes, carbon ( 13 C), nitrogen ( 15 N) and sulphur ( 34 S), to test the hypothesis that dietary segregation in cohabiting invasive mysids (Limnomysis benedeni and Katamysis warpachowskyi) and gammarids (Dikerogammarus villosus and Gammarus roeselii) will be reflected by differences in isotope values. Furthermore, IsoError mixing models were used to estimate the relative contributions of periphyton and seston to the invaders’ diets. Whole tissue 13 C, 15 N and 34 S analysis in L. benedeni and K. warpachowskyi i...
