Fig. 2: Changes in Amazon vegetation resilience since the 1990s and from 2003.
From: Pronounced loss of Amazon rainforest resilience since the early 2000s
a, A map of the Kendall τ values of individual grid cells from 2003. b, Histogram of the Kendall τ values for the Amazon rainforest, considering data from 2003 onwards. Of the grid cells, 76.2% have a positive Kendall τ value from 2003 onwards and 77.8% have this for the full time series. c, Mean VOD AR(1) time series (solid line) along with ±1 s.d. (dotted lines) created from grid cells that have BL fraction ≥80% in the Amazon basin and also contain no human land use (main text and Methods). The full AR(1) time series from 1991 (grey) has a Kendall τ value of 0.589 (P = 0.006) and from 2003 (black), a value of 0.913 (P < 0.001). Note that the AR(1) values are plotted at the end of each 5-yr sliding window. Country and Amazon basin outlines produced as described in Fig. 1.
