The probability that higher-nematine sister species have different niches in relation to time since their divergence. Data on pairwise niche differences (1 = different hosts and/or larval feeding habits; 0 = identical or overlapping niches) and split ages (= relative time since common ancestor) was taken from the 35 terminal sister-taxon pairs in the Bayesian MCC tree (Fig. 4), and the probability curve was estimated using logistic regression.
