  • Challenges to Gray Wolf Recovery in Washington, Oregon, and Northern California

    Creator:
    Kriz, Matthew A.
    Abstract:
    Gray wolves (Canis lupus) are the most socially polarizing species listed under the Endangered Species Act. Wildlife management practices at local, state, and federal levels include lethal control to resolve stakeholder and wolf conflicts as a last resort. There is little experimental evidence that lethal control is effective in this...

    Holma, Maija, Kulmala, Soile, and Lindroos, Marko
    Abstract:
    Conservation goals and resource use can easily conflict when externalities exist. This is the case in the Baltic Sea with grey seal (Halichoerus grypus) and Atlantic salmon (Salmo salar). Both of the species have been defined as critically endangered in the late 20th century but due to conservation schemes, harvest...

  • 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...
