Fig. 3: Change in occupation of morphospace under extinction and conservation.
From: Threat reduction must be coupled with targeted recovery programmes to conserve global bird diversity
pPC1 is a descriptor of body size, pPC2 is associated with wing morphology and pPC3 is associated with beak and tail morphology (for trait loadings, see Supplementary Table 3). a,b, Predicted proportional decline in functional trait space occupation in the next 100 years under the baseline extinction scenario with respect to pPC1 and pPC2 (a) and pPC3 and pPC2 (b). c,d, Averted proportional decline under the complete abatement scenario for pPC1 and pPC2 (c) and pPC2 and pPC3 (d). In all panels, grey colour shows areas where no functional diversity loss was projected or where no functional diversity loss was avoided under complete abatement (fewer than five pixels in all panels). Analyses based on 9,873 species (of which 2,087 species currently listed as Near Threatened or in threatened categories were modelled and could have reduced extinction risk in the abatement scenarios). A total of 1,000 iterations were run for each extinction scenario. All silhouettes are from Phylopic. In a and c (left to right): Apteryx (Ferran Sayol, CC0 1.0), Mellisuga helenae (Steven Traver, CC0 1.0), Troglodytes hiemalis (Andy Wilson, CC0 1.0), Pteroptochos castaneus (Ferran Sayol, CCO 1.0), Atlantisia rogersi (there was no silhouette of A. rogersi so a silhouette of Gallirallus australis was used instead; T.
