Fig. 3From: Ecological opportunity may facilitate diversification in Palearctic freshwater organisms: a case study on hydrobiid gastropodsEcomorphological disparity in the genera Corrosella and Pseudamnicola. (a) Morphological and elevational disparity-through-time plots displayed for Corrosella and Pseudamnicola. The black solid line indicates the observed disparity. The dashed line and gray area represent the mean and 95% confidence interval, respectively, of the expected disparity under a null model of morphological or elevational evolution along the phylogeny. (b) Estimation of ancestral habitat type through relative time performed in BioGeoBEARS for Pseudamnicola and CorrosellaBack to article page
