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 arid and semi-arid regions in drylands of China. Modularity for arid regions (a) and semi-arid regions (b), and degree for arid regions (c) and semi-arid regions (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 more arid regions (e) and less arid regions (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)
