Publications
Molecular correlates of reproductive isolationBenjamin M Fitzpatrick
Section of Evolution and Ecology, University of California, Davis, 95616, USA
Evolution 56:191-8. 2002..Inasmuch as proteins are more subject to the action of natural selection than are silent DNA polymorphisms, this result provides broad support for a model of selection-mediated allopatric speciation...
Morphology and escape performance of tiger salamander larvae (Ambystoma tigrinum mavortium)Benjamin M Fitzpatrick
Center for Population Biology and Section of Evolution and Ecology, University of California, Davis, California 95616, USA
J Exp Zool A Comp Exp Biol 297:147-59. 2003..We found a positive relationship between tail area and propulsive performance, which supports adaptive interpretations of variation in larval tail shape within and between amphibian species...
Environment-dependent admixture dynamics in a tiger salamander hybrid zoneBenjamin M Fitzpatrick
Center for Population Biology and Section of Evolution and Ecology, University of California, Davis, California 95616, USA
Evolution 58:1282-93. 2004..A third was more likely to have heterozygote excess in ephemeral cattle ponds. These patterns indicate that admixture is influenced by complex genotype-by-environment interactions...
Rates of evolution of hybrid inviability in birds and mammalsBenjamin M Fitzpatrick
Center for Population Biology and Section of Evolution and Ecology, University of California, Davis, California 95616, USA
Evolution 58:1865-70. 2004..I briefly discuss this and other potential explanations...
Retention of low-fitness genotypes over six decades of admixture between native and introduced tiger salamandersJarrett R Johnson
Department of Evolution and Ecology and Center for Population Biology, University of California, Davis, CA 95616, USA
BMC Evol Biol 10:147. 2010..Additionally, we examined the inheritance of quantitative phenotypic variation to better understand how evolution has progressed since secondary contact...
Invasive hybrid tiger salamander genotypes impact native amphibiansMaureen E Ryan
Center for Population Biology, University of California, Davis, CA 95616, USA
Proc Natl Acad Sci U S A 106:11166-71. 2009....
Lethal effects of water quality on threatened California salamanders but not on co-occurring hybrid salamandersMaureen E Ryan
Department of Evolution and Ecology, and Center for Population Biology, University of California, Davis, One Shields Avenue, Davis, CA 95616, USA
Conserv Biol 27:95-102. 2013..That all survivors were hybrids suggests that environmental stress may promote rapid displacement of native genotypes...
Hybrid vigor between native and introduced salamanders raises new challenges for conservationBenjamin M Fitzpatrick
Ecology and Evolutionary Biology, University of Tennessee, Knoxville, TN 37996, USA
Proc Natl Acad Sci U S A 104:15793-8. 2007..The ecological consequences for other native species are unknown...
Recent divergence with gene flow in Tennessee cave salamanders (Plethodontidae: Gyrinophilus) inferred from gene genealogiesMatthew L Niemiller
Department of Biology, Middle Tennessee State University, Murfreesboro, TN 37132, USA
Mol Ecol 17:2258-75. 2008..These results strongly favour the hypothesis that Tennessee cave salamanders originated from spring salamanders via divergence with gene flow...
The geography of mammalian speciation: mixed signals from phylogenies and range mapsBenjamin M Fitzpatrick
Section of Evolution and Ecology and Center for Population Biology University of California, Davis 95616, USA
Evolution 60:601-15. 2006..Yet, even if few clades provide clear signals, meta-analytic approaches such as ARC may set bounds on the prevalence of alternative modes of speciation...
Introduction history and habitat variation explain the landscape genetics of hybrid tiger salamandersBenjamin M Fitzpatrick
Department of Ecology and Evolutionary Biology, University of Tennessee, Knoxville 37996, USA
Ecol Appl 17:598-608. 2007..Management favoring natural habitat characteristics may substantially decrease the rate of spread of introduced alleles...
