Extended Data Fig. 6: Associations between life history continuums and fish characteristics.
From: Diverging fish biodiversity trends in cold and warm rivers and streams
A) Local and introduced fish species do not differ in their life history strategies (opportunistic: χ2(1) = 0.377, p = 0.539; equilibrium: χ2(1) = 0.142, p = 0.707; periodic: χ2(1) = 0.583, p = 0.445). B) Non-game species tend to be opportunistic, and game speies tend to be periodic (opportunistic: χ2(1) = 25.843, p = 0.0000003; equilibrium: χ2(1) = 0.276, p = 0.600; periodic: χ2(1) = 16.525, p = 0.0005). Significance was determined by two-sided chi-square tests. Points and errors in A) and B) are model-estimates and 95% confidence intervals based on a beta distribution, holding game/non-game and local/introduced statuses at their proportional values, respectively. C) The opportunistic continuum is correlated with fish temperature preference. No relationship exists between the periodic continuum and temperature. In C), lines represent simple linear model with 95% confidence interval bands. For all, n = 389 independent fish species.
