Overlooked threat: Dams trigger temperature-driven disease in iconic salmonid fish

A new study published in Communications Biology reveals a critical, yet previously overlooked, environmental consequence of man-made dams constructed across rivers and streams. By investigating a key indicator species of ecosystem health, the brown trout (Salmo trutta), researchers from the Estonian University of Life Sciences and the Swedish University of Agricultural Sciences demonstrated that small river impoundments significantly elevate wat…
