The ecology of ocean acidification : integrating the effects of pH variation among other environmental stressors on biogeography and organismal performance in rocky intertidal communities

Creator:: Rose, Jeremy M.
Abstract:: Ocean Acidification (OA) has emerged as a major threat to marine ecosystems, particularly regarding calcifying organisms. A growing body of literature describing laboratory investigations into pH stress indicates broadly deleterious effects for calcifiers, but responses vary greatly across taxa and can be influenced by variations in other environmental characteristics. Scaling...

Patterns of macrophyte wrack deposition on sandy beaches of the Pacific Northwest coast, U.S.A.

Creator:: Reimer, Jessica N.
Abstract:: Dislodged macroalgae and seagrasses, also known as marine wrack, frequently wash into coastal ecosystems from the ocean and are potentially important ecological resources for biological communities. These!nutrient and organic matter subsidies may be especially important on sandy beaches, where little in situ primary productivity exists for higher trophic levels. To...

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....

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...

Nearshore distribution of barnacle and mussel larvae and oceanographic mechanisms of onshore transport and delivery

Creator:: Tyburczy, Joe A.
Abstract:: Recruitment of larvae from the plankton is an important determinant of community structure in marine systems. In populations of many marine species, recruitment determines the basic demographic parameters of immigration, emigration, and reproduction. Moreover, the effect of recruitment as an "ecological subsidy" can determine the strength of interactions among species...

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,...

Drivers of Kelp Forest Responses to Global Change: From Populations to Policies

Creator:: Hamilton, Sara L.
Abstract:: Kelps are large brown algae in the order Laminariales and are foundation species that form the basis of kelp forests. Present across a quarter of the world’s coastlines, kelp forests provide diverse services to coastal communities, as habitat for commercially and culturally important species, as a food source for humans...

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...

Community organization and succession in rocky intertidal surfgrass beds

Creator:: Turner, Teresa
Abstract:: Succession and organization of rocky intertidal zone surfgrass beds (Phyllospadix scouleri Hook) were examined experimentally at two sites on the Oregon coast. The interaction of three attributes of the plant -- high persistence, high preemption, and slow recovery -- strongly influences the organization of surfgrass beds. Permanent plots indicate that...

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...
