Fig. 5: Contribution of different barrier types to habitat fragmentation across fish migration categories and barrier passability levels.

Fig. 5

Comparison of habitat fragmentation by barrier type across different fish migration categories (potamodromous, diadromous, non-migratory, and unknown [NA]) and passability scenarios. This set of graphs displays the Fragmentation Index (FI) and average fragmentation index (^FI) for four barrier types (large dam, small dam, weir, and sluice gate) across various passability values, stratified by migratory behavior of fish species. Each point represents the mean FI, and the error bars indicate the 95% confidence interval (CI). Letters above each box (e.g., “a”, “b”) denote statistical groupings based on post-hoc comparisons, shown at 0.3 passability only, as patterns across all modeled passability levels were similar.
