From: Genomic signatures of convergent shifts to plunge-diving behavior in birds
a Scatter plot showing number of convergent sites per gene versus divergence time for all pairs of species. Solid circles denote pairs in the focal set (i.e., those that have convergently evolved plunge-diving behavior or independently colonized islands), and hollow circles denote non-convergent pairs. Point colors correspond to plunge-diving behavior and island-dwelling (see legend). Lines are linear fits to illustrate trends. The effect size for plunge-diving behavior was η2 = 0.08, interpreted as a medium effect size36. Labels depict exemplar convergent (pair 1: Corythornis vintsioides and Ceyx argentatus) and non-convergent species pairs (pair 2: Ceyx cyanopectus and Ceyx argentatus; pair 3: Chloroceryle Americana and Chloroceryle inda), illustrated on the tree in (b).
