  • 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...

  • Chemical signaling and pheromone evolution in plethodontid salamanders

    Creator:
    Palmer, Catherine Anne
    Abstract:
    My dissertation focuses on the evolutionary forces that have shaped the chemical signaling system of plethodontid salamanders. Pheromones mediate two phases of plethodontid reproduction: mate attraction prior to courtship and female persuasion during courtship. Substrate-borne chemical signals are believed to play an important role in mate attraction for these animals....

  • 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...

  • 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...

  • 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...
