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...

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...

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...

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....

Phytoplankton shading of marine benthic macrophytes: Implications for intertidal community structure

Creator:: Kavanaugh, Maria T.
Abstract:: Previous observations of light levels and phytoplankton abundances along the Oregon coast demonstrated that phytoplankton attenuated light sufficiently to potentially limit the growth of intertidal macrophytes and therefore structure local intertidal communities. Inspired by this observation, in spring 2004, I initiated a study to quantify the direct and indirect benthic...

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...

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...

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...

Oceanographic influences on rocky intertidal communities : coastal upwelling, invertebrate growth rates, and keystone predation

Creator:: Sanford, Eric (Eric David)
Abstract:: The influence of large-scale processes on natural communities has become one of the central issues of modern ecology. I combined field and laboratory studies to investigate the effects of variation in coastal upwelling on rocky intertidal communities along the central Oregon coast. I examined whether the growth of intertidal barnacles...
