  • 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...
