Fig. 4From: Evolution in an extreme environment: developmental biases and phenotypic integration in the adaptive radiation of antarctic notothenioidsMorphological disparity through time. a Disparity plot for all notothenioids, b Trematominae, and c Channichthyidae. Estimated disparity through time is shown in solid line. Median disparity simulated under Brownian motion condition is shown in dashed line and the grey polygon represents 95 % confidence interval of the simulated disparity. The most recent 20 % of the tree was discarded (masked by light grey in figure) to avoid tip over-dispersion when estimating MDI [40]Back to article page
