WHAT THE EVIDENCE SAYS
Factorial nitrogen/phosphorus additions above and below low-gradient river segments showed downstream nitrogen response during low flow, but stronger upstream co-limitation during high flow. Macroinvertebrate grazer density also affected the algal chlorophyll response.
WHY IT MATTERS / OUR READ
Geomorphic position and grazers modify nutrient consequences of wildfire; one downstream station can miss important contrasts.
CAVEATS / UNCERTAINTY
Three fire-scar streams, local nutrient-diffusing substrates and chlorophyll response; not a direct whole-river restoration measure.
