  • The Primacy of Mammals as Seed Dispersers and Predators in Salmon-Bearing Ecosystems

    Creator:
    Harrer, Laurie E. F.
    Abstract:
    Plants often encase seeds in a nutritional reward to incentivize seed dispersal by birds and mammals, but these seeds may also be removed and destroyed by seed predators. Although birds are typically thought to be the primary seed dispersers of berries in temperate systems, in southeast Alaska and other salmon-bearing...

  • Extensive Resource Subsidies by Salmon-Supported Bears to Granivores

    Creator:
    Shakeri, Yasaman N.
    Abstract:
    In salmon-rich, northern coastal environments brown bears can occur at high densities and exert wide-ranging effects on ecosystem processes. Bear consumption of seasonally available fruit may provide important seed dispersal services to plants, and by extension, influence the ecology of seed consumers such as small mammals. In this study, we...
