  "abstract": "River damming alters hydrology, light availability and nutrient dynamics, thereby reshaping both pelagic and benthic primary producers. In double-dam systems, it remains unclear whether the two structures function as a single unit (“double-dam effect”) or whether the downstream dam adds cumulative impacts (“cascade effect”). Over two hydrological years, we investigated the responses of phytoplankton and periphyton to cascading dams, along the Sélune River (France), focusing on photosynthetic activity, biomass and assemblage. Using multivariate analyses, we quantified the relative influence of local environmental and climatic conditions (light, temperature, turbidity, nutrient concentrations and stoichiometry, conductivity, pH, dissolved oxygen, rainfall), spatial position along the river continuum, habitat type (lotic vs. lentic), and season on both communities. Local environmental factors explained most of variance in phytoplankton and periphyton, with light availability, temperature, and nutrient stoichiometry (TDN:TDP) as the dominant drivers. By explicitly testing cascade versus double-dam effects through comparisons of biological variables (activity, biomass and species abundances) between dams and with the downstream lotic station, we found evidence for a single-dam effect for both phytoplankton and periphyton. This pattern likely reflects short water residence times, which constrain the development of cumulative impacts along the dam cascade.",
