  • The ecological consequences of the reduction of species diversity : experimental approaches

    Creator:
    Allison, Gary William
    Abstract:
    The influence of loss of diversity on community dynamics and ecosystem functioning has recently received considerable attention. Although study of biodiversity has a long history within ecology, empirical investigations exploring consequences of loss have been rare. Because many factors confound diversity comparisons, experimental manipulations of diversity offer the most direct...

  • Patterns and dynamics of context-dependency in the marine rocky intertidal

    Creator:
    Berlow, Eric Layani
    Abstract:
    As ecologists are being called upon to predict the consequences of human perturbations to natural communities, an important goal is to understand what factors drive variability or consistency in nature. In the rocky intertidal of San Juan Island, Washington, a comparative experimental approach was used to investigate spatial and temporal...

  • The effects of biomechanical and ecological factors on population and community structure of wave-exposed, intertidal macroalgae

    Creator:
    Blanchette, Carol A.
    Abstract:
    I examined the biomechanical factors that influence the sizes of intertidal macroalgae by studying a population of Fucus gardneri at Fogarty Creek Point, OR. I constructed a mathematical model to predict optimal sizes and probabilities of survival for Fucus under conditions of high and low wave exposure. Predicted optimal sizes...

  • Non-harvest human impacts to rocky intertidal habitats : a pilot project

    Creator:
    Fox, David S.
    Abstract:
    Oregon's rocky intertidal habitats have been subjected to gradually increasing human-use pressures as the coastal and tourist populations have risen over the years. Brosnan and Crumrine (1991,1992) have documented impacts to intertidal communities at Yaquina Head, Sunset Bay, and Haystack Rock that have resulted from people walking on the intertidal...
