  • Trophic cascades and large mammals in the Yellowstone ecosystem

    Creator:
    Painter, Luke E.
    Abstract:
    Reintroduction of wolves to Yellowstone National Park (YNP) in 1995-96 provided a rare opportunity to observe the response of an ecosystem to the return of a top predator, including possible reversal of decades of decline of aspen, cottonwood, and tall willows suppressed by intensive herbivory on elk winter ranges. To...

    Abstract:
    A table containing data from random sampling plots in 87 randomly located aspen stands in northern Yellowstone, repeating measurements by Painter et al. (2014). Stands were relocated using GPS coordinates from 2012. Each stand contained one plot 2x30 m, extending from the live, dead or fallen tree nearest the GPS...

  • Multi-scale relationships between aspen and birds in the northern Yellowstone ecosystem

    Creator:
    Hollenbeck, Jeff P., 1967-
    Abstract:
    I conducted a multi-scale evaluation of aspen – bird relationships in the northern ungulate winter range of the northern Yellowstone ecosystem during June 2001-03. Questions addressed were: (1) Does bird diversity increase with conifer presence in aspen stands? (2) Given known habitat selection cues, are migrating birds passively intercepted by...

  • 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...
