Nutrient co‐limitation of primary producer communities

Ecology Letters (2011) 14 : 852–862 Abstract Synergistic interactions between multiple limiting resources are common, highlighting the importance of co‐limitation as a constraint on primary production. Our concept of resource limitation has shifted over the past two decades from an earlier paradigm of single‐resource limitation towards concepts of co‐limitation by multiple resources, which are predicted by various theories. Herein, we summarise multiple‐resource limitation responses in plant communities using a dataset of 641 studies that applied factorial addition of nitrogen (N) and phosphorus (P) in freshwater, marine and terrestrial systems. We found that more than half of the studies displayed some type…
