  • Grazing, nutrients, and marine benthic algae : insights into the drivers and protection of diversity

    Creator:
    Guerry, Anne D., 1973-
    Abstract:
    Two of the most powerful ways in which humans have altered ecosystems are by increasing productivity and changing the densities of important consumers. The bottom-up effects of productivity and the top-down effects of consumers have been identified as primary determinants of biological diversity, though the links between them remain unclear....

  • Effects of environmental stress on intertidal mussel reproduction

    Creator:
    Petes, Laura E.
    Abstract:
    Environmental stress can negatively affect the ability of organisms to reproduce. Energetic trade-offs exist in all organisms, and under stress, energy may be allocated away from reproduction and towards physiological defense and repair mechanisms. The rocky intertidal environment is ideal for investigating the influence of environmental stress, as organisms are...

  • Linking marine communities and ecosystems : invertebrates mediate nutrient availability in intertidal communities

    Creator:
    Bracken, Matthew E.
    Abstract:
    While community ecologists have traditionally focused on local-scale processes, it has become apparent that a broader perspective, which explores the community-level ramifications of material fluxes within and between ecosystems, is necessary to effectively evaluate bottom-up influences on community structure and dynamics. In this dissertation, I employed ecosystem principles to understand...
