“…The unexpected shift (or lack of shift) in LHT observed in three different gobiid species populations, all at the very start of the colonisation process, reported in our paper (Konečná et al. ) supports such a scenario.…”

“…Indeed, environmentally controlled gene expression (epigenetics) presumes that shifts in LHT will be, to some extent, controlled by environmental cues, which is our basic premise (see the title of our paper; Konečná et al. ). It has to be stressed, however, that LHT shifts during the invasion process can also be driven by other mechanisms, such as evolution or allocation of resources to reproduction at the expense of somatic growth (Copp & Fox ; Fox & Copp ).…”

“…In his reaction to our paper ‘Environment not ‘nativeness’ dictates reproductive trait shifts in Ponto‐Caspian gobies’ (Konečná et al. ), Kováč (‘The fish itself, not only environment, should be considered in studying invasion success’; ) disagree with what he considers a misinterpretation of his theory of ‘alternative ontogenies and invasive potential’ (herein AOIP; Kováč ). In doing so, he questions the reliability of our results by criticising our methodology.…”

“…In contrast, environmental settings were of inferior importance in our study and we detected only minor or no correlation of biological trait values with environmental factors. Similarly, Konečná, Janáč, Roche, and Jurajda () could not identify any environmental factor correlating with goby population characteristics, either. These authors observed reduced fecundity values in N. melanostomus and also in P. kessleri and Neogobius fluviatilis in invaded habitats and suggested altered environmental settings as a possible explanation.…”

The relative importance of species-specific biological trait characteristics and environmental factors in invasions of nonindigenous species remains controversial because both have mostly been studied independently. Thus, the main objective of this study was to examine the correlation of biological traits with environmental variation in the globally invasive round goby Neogobius melanostomus from the upper Danube River.Based on a sample of 653 specimens along a continuous 200 km river pathway, links between nine environmental factors (substrate-type, six water measurements, and the communities of fishes and macroinvertebrates) and seven biological traits (nutritional and energetic status, trade-offs of parasite resistance and resource allocation, and three growth proxies) were analyzed. Biological trait values of N. melanostomus hardly correlated with the environment, could not explain invasion progress and imply a general low overall importance for invasion success. Instead, alternative individual lifehistory trajectories appear to determine invasion success. This is in line with up to 15% of all specimens having outlying biological trait values of potential adaptive value, suggesting a considerable importance of adaptive trait variation among single individuals for the whole invasion progress. This "individual trait utility hypothesis" gives an alternative explanation for success of invasive species by single individuals carrying particular traits, and it should be specifically targeted and analyzed at currently invaded sites.
