Advancing improvement in riverine water quality caused a non-native fish species invasion and native fish fauna recovery

Abstract The knowledge of biotic and abiotic drivers that put non-native invasive fishes at a disadvantage to native ones is necessary for suppressing invasions, but the knowledge is scarce, particularly when abiotic changes are fast. In this study, we increased this knowledge by an analysis of the...
