Additional file 4 of Under pressure: phenotypic divergence and convergence associated with microhabitat adaptations in Triatominae

subject

description

Additional file 4: Figure S1. Phenotype–microhabitat–phylogeny correspondences. Multispecies coalescent species tree (as in Fig. 9 of the main text), with pictures (approximately to the same scale) of adult Rhodnius ecuadoriensis and its closest relatives—R. colombiensis, R. pallescens and R. pictipes. The distribution of phenotypes along the phylogeny suggests that the common ancestor of the diverse R. ecuadoriensis forms was most likely a relatively large, straw-like-colored bug. Similarly, the distribution of primary microhabitats suggests that a shift of southern-Andean populations from palm crowns (green stars) to vertebrate nests (orange circles) resulted in convergence towards the small-size, short-head/wing typical R. ecuadoriensis phenotype; the combined star/circle symbol indicates that northern-lowland Manabí bugs are primarily palm-dwelling but may also exploit nest microhabitats. Rhodnius ecuadoriensis populations: N-A Northern-Andean (Tsáchilas), N-L northern-lowland (Manabí), S-A southern-Andean (El Oro and Loja in Ecuador; La Libertad and Cajamarca in Peru).
