2.2 Trait selection
We selected seven plant traits for each species: specific leaf area (SLA), leaf dry matter content (LDMC), leaf area (LA), leaf thickness (LT), leaf carbon content (LCC), leaf nitrogen content (LNC) and vegetation height (VH). These traits are widely recognized as good predictors for reflecting different plant species strategies for acquiring, using and conserving resources, including light, nutrients and water (Maire et al., 2009; Pinho et al., 2018). All of these were measured in field, based on standard methods of Pérez-Harguindeguy et al. (2013). More details of the trait information were listed in Supplementary material (Table S1).
