  • Reproductive implications of parasitic infections and immune challenges in garter snakes

    Creator:
    Uhrig, Emily J.
    Abstract:
    Parasitic infections and immune challenges can affect host reproductive fitness and, ultimately, the evolution of host populations in a myriad of ways. The fitness implications of parasitic infections range from increased host mortality to subtle changes in reproductive investment. From alterations of behaviors, sexual signaling, and competitive ability to changes...

  • Chronobiology of garter snakes : environmental and hormonal mechanisms mediating hibernation and reproduction

    Creator:
    Lutterschmidt, Deborah I.
    Abstract:
    Most vertebrates exhibit seasonality in many life history traits. Such seasonal rhythms are temporally organized via the transduction of environmental cues (e.g., photoperiod, temperature) into appropriate endocrine signals. However, among ectothermic vertebrates that undergo continuous winter dormancy, temperature is the only environmental cue available for synchronizing seasonal rhythms. Most intriguing...
