Anaemic Streams: Iron and Essential Trace Metals Frequently Limit Primary Producer Biomass. [PDF]
Ecol LettNutrient enrichment experiments in 41 streams across the eastern United States demonstrate that trace metals can limit the growth of primary producers. Trace metals are frequently co‐limiting with macronutrients and the availability of N and P in streams and watersheds are predictive of Fe and Zn limitation status.
