Figure 5From: Transitions between Andean and Amazonian centers of endemism in the radiation of some arboreal rodentsAlternative hypotheses for the evolution of bamboo rats. Sister relationships are constrained to be either (a) Olallamys-Dactylomys or (b) Kannabateomys-Dactylomys. These topologies are statistically equivalent to the unconstrained topology in Figure 4 that finds an Olallamys-Kannabateomys relationship and all three genera unresolved in a polytomy (0.41 PP). Each analysis is pruned from results conducted in BEAST on the full 5-gene data set. For symbols, refer to the legend in Figure 4. See Table 4 for additional details on transition timing and polarity.Back to article page
