Fig. 12From: How do changes in flow magnitude due to hydropower operations affect fish abundance and biomass in temperate regions? A systematic reviewSummary flow chart of univariate mixed models and resulting significant moderators: (a) direction of flow magnitude alterations; (b) presence of alterations to other flow components; (c) sampling method; (d) sampling season; (e) life stage. *Indicates moderately significant effect (p < 0.1). Dashed boxes indicate statistically significant negative effects, thick solid line boxes indicate statistically significant positive effects (i.e., fish abundance is greater in the After period than the Before period). k: number of datasets (i.e., effect sizes); g: Hedges’ g mean effect size; CI: 95% confidence intervalBack to article page
