Phylogenomic Analysis of Fundulidae Using RNA-Sequencing Data
by Rodgers, Rachel, M.S., Southern Illinois University at Edwardsville, 2017, 72; 10265232
Abstract (Summary)

Fishes of the New World cyprinodontiform family Fundulidae display a wide variety of tolerance to environmental conditions, making them a model system for comparative, evolutionary, and environmental studies. The lack of a robust and fully resolved phylogeny for family Fundulidae and its most speciose genus Fundulus remains an impediment to future research. This study utilized novel RNA-sequencing data to generate a phylogeny for 16 members of Fundulidae to better refine interspecies relationships. Maximum likelihood and Bayesian analyses generated identical phylogenies with robust statistical support at each node. While many past hypothesized evolutionary relationships were reinforced, several alternative relationships are hypothesized at deeper nodes in the Fundulidae phylogeny, rendering genus Fundulus paraphyletic.
