Environment not "nativeness" dictates reproductive trait shifts in Ponto-Caspian gobies
Original language description
Comparative studies revealing how species’ traits change after invading new areas are lacking for a number of taxa. This includes Ponto-Caspian gobiid fishes, which have recently invaded a number of temperate Holarctic water systems. We compared the reproductive traits of three gobiid species (round goby Neogobius melanostomus, monkey goby N. fluviatilis, bighead goby N. kessleri) from both native and recently established non-native populations, while controlling for effect of methodology and investigator. nFor all three species, non-native populations demonstrated significantly lower fecundity (number of offspring) than native populations. On the other hand, no significant difference was observed in size-at-maturity or presence of batch-spawning. As identical responses were observed in multiple species, this strongly suggests that gobiid reproductive characteristics are influenced primarily by local environmental conditions. Placed in context with present knowledge of native and non-native gobiid reproduction, the results indicate no unambiguous effect of “nativeness and disprove the theory that recently established non-native populations automatically shift to a more altricial (r-based) strategy.n
