  1. pmc Whole genome sequencing of mutation accumulation lines reveals a low mutation rate in the social amoeba Dictyostelium discoideum
    Gerda Saxer
    Department of Ecology and Evolutionary Biology, Rice University, Houston, Texas, United States of America
    PLoS ONE 7:e46759. 2012
    ..This hypothesis is supported by a significantly lower mutation rate per cell division in multicellular eukaryotes compared with unicellular eukaryotes...
  2. pmc Spatial structure leads to ecological breakdown and loss of diversity
    Gerda Saxer
    Department of Zoology, University of British Columbia, 6270 University Boulevard, Vancouver, British Columbia, Canada V6T 1Z4
    Proc Biol Sci 276:2065-70. 2009
    ..Although spatial structure is frequently observed to be a major promoter of diversity, our results indicate that it can also have negative impacts on diversity...

    Gerda Saxer
    Department of Ecology and Evolutionary Biology MS 170, Rice University, 6100 Main Street, Houston, TX 77005, USA
    BMC Evol Biol 10:76. 2010
    ..We expected that some strains would be out-competed in both treatments. In addition, we expected that low relatedness might allow the persistence of social cheaters as it provides opportunity to exploit other strains...
  4. pmc The repeatability of adaptive radiation during long-term experimental evolution of Escherichia coli in a multiple nutrient environment
    Gerda Saxer
    Department of Biology and Biochemistry, University of Houston, Houston, Texas, United States of America
    PLoS ONE 5:e14184. 2010
    ..The two-resource environment imposed similar selection pressures in independent populations and promoted parallel phenotypic adaptive radiations in all independently evolved microcosms...
  5. pmc Unparallel diversification in bacterial microcosms
    Jabus Tyerman
    Department of Zoology, University of British Columbia, 6270 University Boulevard, Vancouver, British Columbia, Canada V6T 1Z4

    Clea Scala
    Department of Ecology and Evolutionary Biology, Rice University, Houston, Texas, United States of America
    PLoS ONE 7:e46150. 2012
    ..The coding repeat loci are not significantly less variable than similar non-coding triplet repeats. This pattern is consistent with these amino-acid repeats being largely non-functional sequences evolving primarily by mutation and drift...

    Maren L Friesen
    Department of Zoology, University of British Columbia, 6270 University Boulevard, Vancouver, British Columbia V6T 1Z4, Canada
    Evolution 58:245-60. 2004
    ..Our results have implications for understanding the evolution of cross-feeding polymorphism in microorganisms, as well as adaptive speciation due to frequency-dependent selection on phenotypic plasticity...

    Department of Biochemistry and Cell Biology, Rice University, Houston, TX 77005 1892, USA
    Proc Natl Acad Sci U S A 109:21408-13. 2012
    ..Taken together, these findings support an important role for readily accessible small steps in protein evolution that can, in turn, greatly increase the fitness of an organism during natural selection...
