Question:
What controls nutrient uptake rates in streams?
Author: Asger LIndberg-NielsenAnswer:
Controls on nutrient uptake: - Assimilation bu autotrophs - Heterotrophic uptake or transformation - Physical adsorption (especially P) - Hydrolic storage (I transient zones går vanedt langsomt så her kan N nå at reagere piv meget. Så her kan der ske meget N transformation. ) - Ion exchange Chemical complexation High Q (vandføring) also means higher volume så er der mindre probability for cantact. Og vandet ryger hurtigt ud. Stream size er også vigtig. jo større stream jo længere traveler nutrients så højere Sw
