  • The Influence of Prey Predictability on the Foraging Behavior and Movement of Intertidal Predators

    Creator:
    Hennessey, Shannon M.
    Abstract:
    Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or maintain population-, community-, or ecosystem-level patterns. Individual diet variation, defined as individual variation in food resource use within a population that is consistent over time, is...

  • Harlequin duck demography during winter in Prince William Sound, Alaska : effects of the Exxon Valdez oil spill

    Creator:
    Esler, Daniel
    Abstract:
    The 1989 Exxon Valdez oil spill was a major perturbation of nearshore habitats of Prince William Sound, a wintering area for harlequin ducks (Histrionicus histrionicus). This research was designed to evaluate harlequin duck population recovery from the oil spill from 1995 to 1998, using a demographic approach to assess both...

  • Candidate Causes, Consequences, and Estimation of Individual Diet Specialization

    Creator:
    Coblentz, Kyle E.
    Abstract:
    Diet variation among individuals within populations is widespread. Often diet differences among individuals are attributable to obvious differences among individuals such as age, sex, or morphology. However, growing evidence suggests that individual diet variation is also common among seemingly identical individuals within populations. This phenomenon has been termed individual diet...

  • Amphibian communities and climate change : Where ecological processes meet evolutionary interactions

    Creator:
    Thurman, Lindsey L.
    Abstract:
    Forecasts of the impacts of climate change have traditionally focused on individual species and their phenotypes, phenology, or distribution. However, shifts in species distributions and the resulting reorganization of community composition represent an important violation to the assumption of species acting in isolation. Whereas species may respond individualistically to climate...
