  • Complexity of food web interactions in a large mammal system

    Creator:
    Eisenberg, Cristina
    Abstract:
    Food webs consist of a combination of bottom-up (resource-driven) and top-down (predator-driven) effects. The strength of these effects depends on the context in which they occur. I investigated food web (trophic) relationships between wolf (Canis lupus) predation, elk (Cervus elaphus) herbivory, aspen (Populus tremuloides Michaux) recruitment, and fire. The study...

  • Evidence of a trophic cascade among wolves, elk, and aspen in Yellowstone National Park, USA

    Creator:
    Halofsky, Joshua S.
    Abstract:
    According to general top-down trophic theory, in the presence of carnivores, herbivore behavior and/or densities could change and result in an overall decrease in herbivory on plant communities. In this dissertation, I examined the potential relationship between gray wolf (Canis lupus) presence and absence on elk (Cervus elaphus) herbivory of...

  • Limitations to Seedling Regeneration on Tropical Forest Restoration Plantations in Northern Thailand

    Creator:
    Sangsupan, Hathai A.
    Abstract:
    This dissertation investigated potential ecological limitations to seedling regeneration in young, seasonally dry, evergreen forest restoration plantations in northern Thailand. We explored whether recruitment of colonizing tree species in the restoration plantations can be attributed to seed dispersal mode (i.e. abiotic or animal dispersal) and seed size. We did this...
