Figure 5. Relationships between residual lignin and substrate mass after a period of decomposition.

Lv_BD, Lv_BL, Lv_EG, Lv_NA and Lv_PA indicate leaf litter at the BD, BL, EG, NA and PA sites, respectively; St_NA and St_PA indicate sheath litter at the NA and PA sites, respectively; Tg_EG, Tg_NA and Tg_PA indicate twig litter at the EG, NA and PA sites, respectively. Error bars represent the standard deviations of the means (n = 3).
