Table 1.
Comparison of the fit of a Brownian motion (BM) and Ornstein–Uhlenbeck with a single (OU1) or two (OUM) environmental niche breadth optima in OUwie. (The table shows AIC values for each combination of host specialization, environmental PC axis and evolutionary model. Models with the highest AIC support are shown in bold characters.)
