Evolution in an extreme environment: developmental biases and phenotypic integration in the adaptive radiation of antarctic notothenioids

Table 1 Comparison of alternative models of head shape evolution in notothenioids

Model	Log likelihood	AICc	Delta AICc	AICc weight
OU-Diet3	26.1143	-39.50132	0.00	0.693
OU-Diet5	28.42475	-37.24949	2.25	0.225
OU-Single Peak	21.0511	-35.10237	4.40	0.077
Brownian Motion	16.98216	-29.48433	10.02	0.005
Early Burst	16.98212	-26.96424	12.54	0.001

Models are ordered from best to worst based on AICc scores. OU-Diet3: Ornstein-Uhlenbeck (OU) multi-peak model with species assigned to three categories according to feeding habitats (pelagic, intermediate and benthic); OU-Diet5: OU multi-peak model with species assigned to five categories according to feeding habitat and prey items (pelagic-large, pelagic-small, intermediate, benthic-soft, benthic-hard)
