Figure 2.

Consensus Bayesian tree showing phylogenetic relatedness between 21 small mammal species from grassland-forest ecotones. A total of 3.1 Kb from two mitochondrial genes (cytochrome oxidase I [COI], cytochrome b [Cyt-b]) and one nuclear (interphotoreceptor retinoid-binding protein [IRBP]) locus were used to reconstruct the tree. Values above branches indicate Bayesian posterior probabilities/bootstrap obtained from maximum likelihood. Animal shadows on the left are draw on scale to represent variation on body size.
