- Phylogeny of muroid rodents: relationships within and among major lineages as determined by IRBP gene sequencesSharon A Jansa
Bell Museum of Natural History and Department of Ecology, Evolution, and Behavior, University of Minnesota, St Paul, MN, USA
Mol Phylogenet Evol 31:256-76. 2004..A preliminary examination of molar tooth morphology on the resulting phylogeny suggests the triserial murid molar pattern as conceived by evolved at least three times during the course of muroid evolution...
- Different patterns of selection on the nuclear genes IRBP and DMP-1 affect the efficiency but not the outcome of phylogeny estimation for didelphid marsupialsSharon A Jansa
Bell Museum of Natural History and Department of Ecology, Evolution, and Behavior, University of Minnesota, St Paul, 55108, USA
Mol Phylogenet Evol 38:363-80. 2006..Thus, for these two genes, relaxed functional constraints and positive selection appear to improve the efficiency of phylogenetic estimation without compromising its accuracy...

- Adaptive evolution of the venom-targeted vWF protein in opossums that eat pitvipersSharon A Jansa
Department of Ecology, Evolution and Behavior, and J F Bell Museum of Natural History, University of Minnesota, St Paul, Minnesota, United States of America
PLoS ONE 6:e20997. 2011..However, in the arms race implied by our results, venomous snakes are prey, and their venom has a correspondingly defensive function in addition to its usual trophic role...
- Base-compositional heterogeneity in the RAG1 locus among didelphid marsupials: implications for phylogenetic inference and the evolution of GC contentKarl F Gruber
Bell Museum of Natural History and Department of Ecology, Evolution, and Behavior, University of Minnesota, St Paul, Minnesota 55108, USA
Syst Biol 56:83-96. 2007..Both mutation rate and substitution rate are higher in GC-rich didelphid taxa, observations consistent with RAG1 sequences having experienced a higher rate of recombination in the convergent lineages...

Department of Mammalogy, American Museum of Natural History, New York, NY 10024, USA
Biol Rev Camb Philos Soc 87:822-37. 2012..Unfortunately, evolutionary inference is currently limited by ignorance about many relevant facts that can only be provided by future research...
- Tests for positive selection on immune and reproductive genes in closely related species of the murine genus musSharon A Jansa

- Phylogenetic relationships in the genus mus, based on paternally, maternally, and biparentally inherited charactersBarbara L Lundrigan
Michigan State University Museum and Department of Zoology, Michigan State University, East Lansing, Michigan 48824 1045, USA
Syst Biol 51:410-31. 2002..This appears to reflect a localized homoplasy in one partition obscuring the phylogenetic signal from another, rather than differences in gene or genome histories...
