| Brief text description | Relation beween the log of Chlorophyll a and the log of the concentration for SIN and SRP. |
| Long text description | Relation between the mean monthly benthic algal biomass in mg/m2 chlorophyll a and SIN and SRP in (mg.L-1): log10 (Chl a) = 0.483 log10 SIN + 0.109 (rē=0.122, p=0.057) log10 (Chl a) = 0.697 log10 SRP + 0.468 (rē=0.226, p=0.008) Nutrient range: SIN=6.2-232 mg.L-1 SRP=1.3-31.6 mg.L-1 Source data from 30 sites, 25 streams (New Zealand). |
