Stream ecosystem integrity is impaired by logging and shifting agriculture in a global megadiversity center (Sarawak, Borneo)

► We compare ecosystem integrity of pristine vs. logged vs. farmed streams in Borneo. ► We use both functional (leaf breakdown) and structural indicators (associated fauna). ► Both practices alter ecosystem integrity, but the impacts of logging are more severe. ► Mechanized logging affects both the structure and function of stream ecosystems. ► Slash and burn clearing for shifting agriculture affects structure more than function.
