    James P Bogart
    Department of Integrative Biology, University of Guelph, Guelph, ON N1G 2W1, Canada
    Genome 50:119-36. 2007
    ..The reproductive mode used by unisexual Ambystoma appears to be unique; we suggest kleptogenesis as a new unisexual reproductive mode that is used by these salamanders...

    Ke Bi
    Department of Integrative Biology, University of Guelph, Guelph, Ontario, Canada N1G 2W1
    Chromosome Res 16:275-89. 2008

    J P Bogart
    Department of Integrative Biology, University of Guelph, Ontario, Canada
    Heredity (Edinb) 103:483-93. 2009
    ..In the absence of A. jeffersonianum, this Ohio population is likely experiencing a recent switch in sperm donors from A. jeffersonianum to A. barbouri and demonstrates the evolutionary flexibility and dynamics of kleptogenesis...

    Ke Bi
    Department of Integrative Biology, University of Guelph, Guelph, Ontario, Canada
    BMC Evol Biol 10:238. 2010
    ..In contrast to other studies showing that unisexual Ambystoma represent the most ancient unisexual vertebrates, a recent study by Robertson et al. suggests that this lineage has a very recent origin of less than 25,000 years ago...
