Fig. 2: The relationship between the breakpoint date and the primary (baseline) slow driver for the individual (grey) and multiple (coloured) drivers.
From: Earlier collapse of Anthropocene ecosystems driven by multiple faster and noisier drivers
The normalized primary driver trajectories are apportioned into three discrete ranges: low, 0.25–0.35; mid, 0.45–0.55; and high, 0.65–0.75. a–d, Subplots: Lake Chilika model, primary slow driver—fisher population growth, secondary driver—climate change, tertiary driver—fish price (a); Easter Island model, primary slow driver—tree clearance, secondary driver—agricultural carrying capacity, tertiary driver—tree mortality (b); TRIFFID model, primary slow driver—temperature change, secondary driver—disturbance rate (c); Lake Phosphorus model, primary slow driver—phosphorus external input, secondary driver—phosphorus recycling rate, tertiary driver—phosphorus sedimentation rate (d). Model timestep units: Lake Chilika, Easter Island and TRIFFID run in years; timesteps in Lake Phosphorus are unitless. Boxplots depict the median (50th percentile), upper quartile (75th percentile) and lower quartile (25th percentile); individual points represent outliers which fall outside 1.5× the interquartile range from the lower and upper quartiles (as depicted by the boxplot whiskers). See Supplementary Table 3-1 for the number of model simulations underpinning each boxplot.
