A double-edged barrier


Research reveals how dams both hinder native fish migration and help control invasive species. Studies track fish movement, assess climate impacts, and explore innovative restoration strategies


Right: Lower Mekong Basin dams across six riparian countries interfere with fish habitats


(A) Geographic distribution of 52 existing and 45 planned dams, and the habitat ranges of 710 riverine fish species. Colours indicate the number of species at each of the sub-basins. For this analysis, the LMB is divided into 4689 sub-basins


(B) Geographic ranges of two iconic species (the Mekong Giant Catfish and the Royal Featherback) as examples for the species-level resolution of this analysis. Source: https://doi.org/10.1016/j. oneear.2024.05.009
