Tian, Chengzong Yang, Bo García-Girón, Jorge Li, Zhongyang Kua, Zi Xun Du, Xiaopei Xin, Wei Zhou, Xiongdong Duan, Ming Chen, Yushun Animals Introduced Species Fishes Biodiversity Ecosystem Fresh Water Rivers Phylogeny Understanding the resistance of native fauna to biological invasions is essential for predicting and managing freshwater fish diversity under accelerating global change. Using fish and environmental data from 2622 river basins worldwide, we quantified how niche differentiation, phylogenetic and functional diversity, and richness of native species, as well as environmental factors contribute to non-native fish richness and occurrence. Our results show that niche differentiation of native fishes is the key determinant of biotic resistance: when native species occupy broader and more heterogeneous niche spaces, both the richness and occurrence probability of non-native fishes decline significantly, a pattern that holds consistently across global and biogeographic scales. Functional and phylogenetic diversity exert partially constraining effects, yet their influence varies across invasion metrics and spatial scales, thereby limiting their predictive power. Native richness promotes the naturalization of non-native species but does not significantly influence invasion richness. Notably, non-native fish invasions follow a nonlinear latitudinal gradient, intensify with increasing human pressure, and are positively associated with basin area. These findings demonstrate that freshwater fish invasions are jointly shaped by biotic interactions, environmental filtering, and human activities, with native niche differentiation emerging as the primary driver of biotic resistance. By incorporating niche-based mechanisms, this study provides a unifying perspective for reconciling the invasion paradox and offers a process-based foundation for developing integrated invasion management strategies under global change. |
