Catchment-wide interactive effects of anthropogenic structures and river levels on fish spawning migrations. Anthropocene, 43, Article 100400. https://doi.org/10.1016/j.ancene.2023.100400

Worldwide, rivers are extensively fragmented by anthropogenic structures, reducing longitudinal connectivity, inhibiting migration and leading to severe declines in many fish populations, especially for diadromous species. However, few studies have d... Read More about Catchment-wide interactive effects of anthropogenic structures and river levels on fish spawning migrations.
