Agricultural land use shapes short and long‑term bacterial diversity, community structure, and assembly in biofilms of adjacent streams

Key Points

• Bacterial diversity in stream biofilms is significantly shaped by land use practices, affecting both short- and long-term community structure.
• Lands used for agriculture exhibit distinct microbial community assembly processes compared to non-agricultural areas, highlighting ecological impacts.
• Analysis of biofilm microbial communities was conducted across various stream locations, correlating agricultural practices with bacterial diversity changes.
• Understanding these influences can help inform better land management and conservation strategies to protect stream ecosystems.
