  • Evolution of sodefrin precursor pheromones in salamandrid newts

    Creator:
    von Reis, Martha
    Abstract:
    An ancient pheromonal signal is found in aquatic courting salamandrids and terrestrial courting plethodontids, two highly divergent salamander families. In the aquatic courting salamandrids Cynops pyrrhogaster and C. ensicauda, the decapeptide sodefrin is cleaved from a larger 189 amino acid Sodefrin Precursor Factor (SPF) protein and released from a gland...

  • Evolution of a pheromone signaling system in the salamander genus Plethodon (Amphibia: Plethodontidae)

    Creator:
    Picard, Amy L.
    Abstract:
    Animal signaling systems frequently utilize multiple traits to produce and transmit a signal. These system elements may span multiple levels of organization. Functional integration of these traits may be expected to generate concordance in evolutionary pattern among system elements, such that evolutionary change in one system component is correlated with...

  • Pheromone mechanisms and behavioral strategies for maximizing courtship success in a terrestrial salamander, Plethodon shermani

    Creator:
    Vaccaro, Elyse A.
    Abstract:
    Darwin devised the evolutionary theory of sexual selection to account for the manifold extravagances of courtship behaviors and displays. Mating interactions represent a major evolutionary process driving the elaboration, vibrancy, and peculiarity of these courtship traits. For my dissertation research, I strived to elucidate the dynamics that constitute the complex...

  • Chemical cues and the molecular basis of olfactory chemoreception in caudate amphibians

    Creator:
    Kiemnec, Karen M.
    Abstract:
    Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...

  • Mutual mate choice in a terrestrial salamander, Plethodon shermani, with long-term sperm storage

    Creator:
    Eddy, Sarah L.
    Abstract:
    Sexual selection can influence the mating system of an organism through multiple mechanisms. These mechanisms result in variation in reproductive success among individuals, and include scramble competition, endurance rivalries, contests, mate choice and cryptic choice, and sperm competition. Understanding the mating system of a species requires the identification of which...
