  • Succession and stability in two rocky intertidal communities on the central Oregon coast

    Creator:
    Farrell, Terence M.
    Abstract:
    The stability of a limpet-dominated community was assessed in a experiment in which an consumer was temporarily removed. Compared to unmanipulated plots, the limpet-exclusion plots developed greater algal abundance and altered species composition of both algae and barnacles. The community was not perturbed beyond its capacity to recover, since the...

  • Climate change impacts on mountain snowpack presented in a knowledge to action framework

    Creator:
    Sproles, Eric A.
    Abstract:
    Throughout many of the world’s mountain ranges snowpack accumulates during the winter and into the spring, providing a natural reservoir for water. As this reservoir melts, it fills streams and recharges groundwater for over 1 billion people globally. Despite its importance to water resources, our understanding of the storage capacity...

  • Hydrology and geomorphic evolution of basaltic landscapes, High Cascades, Oregon

    Creator:
    Jefferson, Anne (Anne Jarvis)
    Abstract:
    The basaltic landscapes of the Oregon High Cascades form a natural laboratory for examining how geologic setting and history influence groundwater flowpaths, streamflow sensitivity to climate, and landscape evolution. In the High Cascades, highly permeable young basaltic lavas form extensive aquifers. These aquifers are the dominant sources of summer streamflow...

  • Spatial Ecology and Species Interactions among Predators and their Prey

    Creator:
    Ruprecht, Joel S.
    Abstract:
    Carnivores have disproportionate effects in ecological systems but understanding their exact influences on ecosystems is a matter of great complexity and debate. Predators directly impact prey by killing them, and indirectly by modifying their behavior in response to predation risk. Yet how species interact, both among members of a carnivore...
