Fig. 3: Paleoenvironmental correlates and potential drivers of the dynamics of insects.
From: Multiple drivers and lineage-specific insect extinctions during the Permo–Triassic

Bayesian inferences of correlation parameters on origination (blue: a, c, e, g, i, k) and extinction (red: b, d, f, h, j, l) with abiotic factors like global temperature, continental fragmentation, global variation of atmospheric CO2 and O2; with biotic factors like relative diversity through time of Polypodiales ferns, non-Polypodiales ferns, Gymnosperms and spore-plants; and diversity-dependence factors with diversity through time of insect genera. Stars indicate a significant correlation parameter for a given variable (shrinkage weights (ω) > 0.5). Colour and abbreviations as in Fig. 1. Silhouettes from http://phylopic.org/.
