TL;DR: This is the first study demonstrating the contribution of nutrients on the maintenance and spread of antibiotic resistance genes in streambed biofilms under controlled conditions and highlights that nutrients could enhance the effect of emerging contaminants on the dissemination of antibiotics resistance.

TL;DR: The duration of the non-flow period proved to be important for the balance between autotrophic and heterotrophic processes in stream biofilms, with the autotroph processes being less resistant but more resilient.

TL;DR: Intermittent rivers and ephemeral streams (IRES) support highly biodiverse primary producers, including algae, cyanobacteria, and aquatic and riparian plants, who share common traits to cope with a harsh environment whose water table varies and where desiccation is common.

TL;DR: Microbially mediated functions in IRES are perhaps the most critical to freshwater ecosystem services such as nitrogen and carbon cycling and efforts to manage and restore IRES will depend on improved understanding of hydrological controls on microbial communities and functions across space and time.
