FIGURE 1 in Combined molecular and morphological phylogeny of Ephemerellinae (Ephemerellidae: Ephemeroptera), with remarks about classification

FIGURE 1. Combined data (molecular and morphology) mixed model Bayesian analysis topology. The tree represents the 50% consensus of all of the Bayesian topologies that were selected outside of the "burn in". For each node the five squares represent sensitivity of the data to different approaches of analysis. The first square is colored gray when the Bayesian posterior probability was greater than 90. The second square is grayed when the node is supported in the maximum likelihood (ML) tree. The third square is grayed when the node is supported in the maximum parsimony (MP) tree. The fourth square is grayed to represent a greater than 50% bootstrap value. The fifth square is grayed when the node is supported in the maximum parsimony analysis of the morphological data.
