  • Gene flow and the relationship of Plethodon stormi and P. elongatus assessed with 11 novel microsatellite loci

    Creator:
    DeGross, Douglas James
    Abstract:
    Plethodontid salamanders are model organisms for studying evolutionary questions of gene flow, restricted ranges, and speciation. Plethodon, a diverse genus within Plethodontidae, is widely distributed in eastern and western North America. Much research has been based in the eastern United States where diversity of these salamanders is high. Because of...

  • Pheromone Variation in Plethodontid Salamanders

    Creator:
    Chouinard, Adam J.
    Abstract:
    Plethodontid salamanders have served as an informative vertebrate system for studying the role of chemical signals in facilitating social and reproductive behaviors. Individuals produce complex mixtures of chemicals from multiple glandular regions. In total, these secretions convey a wide variety of information, and are important for numerous inter- and intraspecific...

  • Phylogeography, evolution, and conservation in forest-associated Pacific Northwest salamanders

    Creator:
    Wagner, R. Steven
    Abstract:
    Phylogeographic studies of six Pacific Northwest forest-associated salamanders provide insight into historical and contemporary processes on population genetic structure. Among Larch Mountain Salamanders (Plethodon larselli), cytochrome b mitochondrial (mtDNA) sequences (381 bp) and random amplified polymorphic DNA (RAPDs; 34 loci) supported separate Management Units for northern and southern populations (12...
