Fig. 5: Net ecosystem productivity (NEP) changes due to early greenup and delayed snowmelt under each climatic limit.
From: Carbon response of tundra ecosystems to advancing greenup and snowmelt in Alaska
The NEP change (ΔNEP) per 10 days of early greenup or delayed snowmelt with each climatic limit (strongly temperature and water-colimited, SCL; moderately colimited, MCL; weakly water-limited, WWL). The mean value of the sites with the same limit is represented as a bar, with one standard deviation indicated by the vertical line (there is only one weakly water-limited site, therefore no standard deviation line).
