vaseyana ecological system assuming no climate change (NoCC; based on resampled historic
data) and assuming climate change for the A2 scenario (CC) from five Global Circulation Models
(GCM). Legend: MSu-AG = annual grassland; MSu-SAP = shrubland with annual and perennial
grasses; and MSu-TEA = tree encroached or wooded shrubland invaded by annual grass. Climate
change GCMs replicates are mri_cgcm2_3_2a.2.sresa2, ukmohadcm3.1.sresa2, ncar
pcm1.1.sresa2, ncar_ccsm3_0.1.sresa2, and ncar_ccsm3_0.2.sresa2. Error bar represents the 95 %
confidence interval for five replications
