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...

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...

Changing Climate, Changing Contexts : Variation in Rocky Intertidal Predator-prey Interactions Seen Through an Environmental Stress Framework

Creator:: Cerny-Chipman, Elizabeth B.
Abstract:: The multifaceted role of the environment in regulating the structure and dynamics of biological communities has long fascinated ecologists and motivated much debate and research. Now, in a time of accelerated global changes due to human impacts, the need to understand how the environment shapes communities has gained new urgency....

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...

The role of oxygen and other environmental variables on survivorship, abundance, and community structure of invertebrate meroplankton of Oregon nearshore coastal waters

Creator:: Eerkes-Medrano, Dafne I.
Abstract:: The high productivity of Eastern Boundary Upwelling Ecosystems (EBUE), some of the most productive ecosystems in the globe, is attributed to the nutrient rich waters brought up through upwelling. Climate change scenarios for coastal upwelling systems, predict an intensification of coastal upwelling winds. Associated with intensification in upwelling are biogeochemical...

Marine Mass Mortality in a Global Change Context: Impacts on Individuals, Populations and Communities

Creator:: Sullivan Stack, Jenna
Abstract:: Human actions are pushing natural systems into states that have no historical precedent. In response, empirical and theoretical researchers are increasingly focused on developing ways to predict the responses of ecological systems to change. However, significant knowledge gaps remain, often leading to “ecological surprises” where observed impacts of global change...

Scale and Pattern: Delineating the Effects of Local to Regional Processes and Species Identity in Producing Multi-scale Responses of Macroalgae

Creator:: Spiecker, Barbara J.
Abstract:: Understanding and predicting how regional to global scale processes affect macroalgal populations and communities requires elucidating the mechanisms underlying observed patterns. This dissertation identifies some of the underlying mechanisms that produce complex multi-scale responses of macroalgae across space and time by delineating the role of key local environmental drivers and...

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...

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...

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...
