Abstract

Nucleotide sequences from intron 7 of the beta-fibrinogen gene (Fgb-I7) were used to evaluate phylogenetic relationships among members of the genus Sigmodon. In addition, these sequences were combined with mitochondrial cytochrome-b sequences and analyzed from a total evidence perspective. Results from parsimony and Bayesian analyses indicated support for 3 species groups (alstoni, fulviventer, and hispidus). A sister relationship was depicted for S. alleni and S. hirsutus, followed by the addition of S. toltecus; however, little resolution was provided for relationships between other members of the hispidus species group.
