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...

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....

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...

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...

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...

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...

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...

Eelgrass-macroalgae interactions; context-dependency in upwelling-influenced estuaries

Creator:: Hessing-Lewis, Margot
Abstract:: This dissertation investigates the context-dependency of species interactions between seagrass and macroalgae in upwelling-influenced estuaries. In all coastal systems, nutrient loading is multidirectional, resulting from mostly freshwater and marine inputs. The directionality of nutrient inputs may affect the rate of supply of organic matter to the system. In systems where...

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...

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...
