From: Plant trait networks reveal adaptation strategies in the drylands of China
Trait networks of 16 plant traits including leaf tissue density (LD), leaf volume (LV), leaf dry matter content (LDMC), leaf area (LA), leaf thickness (LT), leaf mass per area (LMA), area-based photosynthetic rate (Aarea), leaf phosphorus concentration (LPC), leaf nitrogen concentration (LNC), leaf carbon concentration (LCC), stem phosphorus concentration (SPC), stem nitrogen concentration (SNC), stem carbon concentration (SCC), root phosphorus concentration (RPC), root nitrogen concentration (RNC), and root carbon concentration (RCC) for woody and herbaceous plant life-forms in the drylands of China. Modularity for woody plants (a) and herbaceous plants (b), and degree for woody plants (c) and herbaceous plants (d). Traits with the same background color belong to the same module. The black and red edges represent connections within and between modules, respectively. Absolute importance of structural, economic and chemical traits for woody plants (e) and herbaceous plants (f). Structural, economic and chemical traits are represented by orange, red, and blue colors, respectively. Means with different letters differ from each other (P < 0.05). Error bars represent standard error (SE)
