Figure 1. Tree, shrub and herb plant functional type ANPP:Heinrich Event 1 hosing experiment compared to 17 ka BP normal experiment.

Figure 1

Annual net primary productivity (ANPP) for the aggregated tree (A and D), shrub (B and E) and herb (C and F) plant functional types (PFTs) simulated for the palaeoclimates generated by the Heinrich Event 1 hosing experiment (A–C) and the equivalent 17 ka BP normal experiment (D–F). Lilac shaded areas indicate the extent of the modelled last glacial ice sheets for 17 ka BP [38]; land area is shown for sea-level lowered by 107 m [39]. ANPP is indicated by shading of land areas:white areas have zero ANPP for that PFT; pale grey areas have non-zero but very low ANPP; shades from deep blue through cyan and pale cyan to yellow and orange indicate progressively higher ANPP as shown by the quantitative legend.
