  • Bridging environmental physiology and community ecology : temperature effects at the community level

    Creator:
    Iles, Alison C.
    Abstract:
    Most climate change predictions focus on the response of individual species to changing local conditions and ignore species interactions, largely due to the lack of a sound theoretical foundation for how interactions are expected to change with climate and how to incorporate them into climate change models. Much of the...

  • Impacts of Ocean Acidification on Coralline Algae : From Species to Community Consequences

    Creator:
    Shen, Chenchen
    Abstract:
    Oceanic uptake of rising anthropogenic CO₂ emissions has caused the emergence of ocean acidification as a major threat to marine ecosystems worldwide. Along eastern boundary current systems, seawater is naturally acidified due to coastal upwelling of low pH seawater from depth. Compounded by ocean acidification, upwelling regions are expected to...

  • A limpet kelp interaction : description and definition

    Creator:
    Yates, Kenneth R.
    Abstract:
    The interaction between the acmaeid limpet, Collisella instabilis and the subtidal laminarian, Pterygophora californica involves positive effects on the limpet population and subtle positive or null effects on the kelp. Collisella, which is found only on Pterygophora and another kelp, Laminaria dentigera (Kjellman, 1889), may exploit several features of the...

  • Linkages between mangrove forests and coral reefs : quantifying disturbance effects and energy flow between systems

    Creator:
    Granek, Elise F.
    Abstract:
    Interface habitats are considered valuable natural systems, tightly linked to adjacent habitats through the flow of matter and energy. However, there is limited research on mechanisms of connectivity such as movement of organisms and particulate matter and ways in which anthropogenic disturbance to interface habitats may affect immediate and adjacent...

  • Biodiversity : illustrations of some concepts, causes, and consequences

    Creator:
    Russell, Roland B.
    Abstract:
    Careful analysis and thoughtful synthesis will be necessary for expanding the envelope of ecological understanding. This work is my attempt at communicating both of these, in relation to three questions about our understanding of the structure and dynamics of biological diversity. These questions focus on a) advancing our understanding of...

  • 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...

  • Genetic Structure, Diversity, and Mating System of Leptasterias: Potential for Local Adaptation?

    Creator:
    Boring, Emily L.
    Abstract:
    Understanding of gene flow, connectivity, and diversity is critical to predict the stability of key marine species. The Oregon coast of the U.S.A. shows fine-scale levels of geographic variation in environmental stressors such as temperature, pH, and oxygen levels, prompting questions about the potential for local adaptation. In this thesis,...

  • Predictability and constraints on the structure of ecological communities in the context of climate change

    Creator:
    Barner, Allison K.
    Abstract:
    Ecologists must increasingly balance the need for accurate predictions about how ecosystems will be affected by climate change, against the fact that making such predictions at the ecosystem-level may be infeasible. Although information about responses of individual species to a changing environment is increasing, scaling such information to the community...
