  • Macroscale to local scale variation in rocky intertidal community structure and dynamics in relation to coastal upwelling

    Creator:
    Freidenburg, Tess L.
    Abstract:
    Understanding how large-scale processes (>100 kms) influence ecological communities is currently a major focus in ecology. In marine systems, coastal upwelling, a large-scale oceanographic process in which surface water pushed offshore by winds is replaced by cold, nutrient-rich water from depth, appears to cause variation in rocky intertidal communities. Along...

  • Ecological subsidies to rocky shore communities : setting the stage for community dynamics in the Northeast Pacific

    Creator:
    Krenz, Christopher
    Abstract:
    This dissertation focuses on the importance of pelagic subsidies in the Northeast Pacific to rocky shore community regulation. My results document the patterns of pelagic subsidy supply, determine if those subsidies are correlated with community structure, and examine if community regulation differs between areas of high- and low-subsidies. Understanding how...

  • 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...
