RT Journal Article T1 Leaf dry matter content is better at predicting abovegroundnet primary production than specific leaf area A1 Smart, Simon Mark A1 Glanville, Helen Catherine A1 Blanes, María del Carmen A1 Mercado, Lina María A1 Emmett, Bridget Anne A1 Jones, David Leonard A1 Cosby, Bernard Jackson A1 Marrs, Robert Hunter A1 Butler, Adam A1 Marshall, Miles Ramsvik A1 Reinsch, Sabine A1 Herrero-Jáuregui, Cristina A1 Hodgson, John Gavin AB 1. Reliable modelling of above-ground net primary production (aNPP) at fine resolution is a significant challenge. A promising avenue for improving process models is to include response and effect trait relationships. However, uncertainties remain over which leaf traits are correlated most strongly with aNPP.2. We compared abundance-weighted values of two of the most widely used traits from the leaf economics spectrum (specific leaf area and leaf dry matter content) with measured aNPP across a temperate ecosystem gradient. 3. We found that leaf dry matter content (LDMC) as opposed to specific leaf area (SLA) was the superior predictor of aNPP (R2 = 0 55).4. Directly measured in situ trait values for the dominant species improved estimation of aNPP significantly. Introducing intraspecific trait variation by including the effect of replicated trait values from published databases did not improve the estimation of aNPP. 5. Our results support the prospect of greater scientific understanding for less cost because LDMC is much easier to measure than SLA.
