Fig. 3: Relationships between the probability of non-native fish occurrence and nonnative-native phylogenetic distance across 3008 river basins worldwide.
From: Global freshwater fish invasion linked to the presence of closely related species
a The variation in the occurrence probability of exotic fish species with the mean phylogenetic distance (MPD) between exotic and native fish species. b The variation in the occurrence probability of exotic fish species with the nearest phylogenetic distance (MNTD) between exotic and native fish species. c The variation in the occurrence probability of translocated fish species with the MPD between translocated and native fish species. d The variation in the occurrence probability of translocated fish species with the MNTD between translocated and native fish species. Statistical tests and predictive curves (with 95% confidence intervals) were obtained using generalized linear mixed models (GLMMs), while assuming a binomial error distribution. Statistical significance (p values), variance explained (R2marginal for the fixed effect and R2conditional for both the fixed and random effects), and sample size (n) are presented in the figure. Blue and orange colors are used to highlight the relationships observed in exotic and translocated fish species, respectively.
