This one is of great interest because of several aspects.
1. It directly relates to the Growth Rate Hypothesis (GRH) and provides strong support for its validity in plants, at least at high growth rates. Specifically their data are very consistent with Goren Agren’s new model that predicts a unimodal relationship between plant N:P and growth rate. So, very fast growing plants tend to have low N:P. But so do very slow growing ones! So, be careful!
2. It relates growth, N:P, and water use efficiency and so it is very relevant to a paper Niu Decao is writing right now.
3. ASU & SOLS are now developing a formal research and education relationship with the Smithsonian Tropical Research Institute (STRI), where these authors work. So, this should make for firm grounds for collaboration!
