Chemical signaling and pheromone evolution in plethodontid salamanders

Creator:: Palmer, Catherine Anne
Abstract:: My dissertation focuses on the evolutionary forces that have shaped the chemical signaling system of plethodontid salamanders. Pheromones mediate two phases of plethodontid reproduction: mate attraction prior to courtship and female persuasion during courtship. Substrate-borne chemical signals are believed to play an important role in mate attraction for these animals....

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....

Connecting microevolutionary processes with macroevolutionary patterns across space and time

Creator:: Uyeda, Josef C.
Abstract:: Whether microevolutionary processes can explain macroevolutionary patterns has long been a matter of contentious debate. The debate has persisted largely because of the challenging task of connecting microevolutionary theory, which examines population-level phenomena on the generation scale, to data collected across larger spatial and temporal scales. My dissertation research broadly...

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...

On the evolution of correlated color traits in garter snakes

Creator:: Westphal, Michael F.
Abstract:: How complex traits evolve continues to be a major focus of evolutionary investigation. A current topic of debate is the hypothesis that the phenotypic integration of complex traits gives rise to evolutionary constraints. I studied two color traits in the common garter snake, Thamnophis sirtalis, that show a high level...

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...

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...

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...

Aquatic insect adaptations to different flow regimes

Creator:: Yamamuro, Asako Melody
Abstract:: My thesis explored the effects of environmental variability on population dynamics and community composition of aquatic insects. Environmental variability in the form of flow regime in streams can limit the distribution and life-history traits of aquatic insects. I used tributaries to the McKenzie River in Oregon with dramatically different flow...

Predictability and constraints on the structure of ecological communities in the context of climate change

Creator:: Barner, Allison K.
Abstract:: Ecologists must increasingly balance the need for accurate predictions about how ecosystems will be affected by climate change, against the fact that making such predictions at the ecosystem-level may be infeasible. Although information about responses of individual species to a changing environment is increasing, scaling such information to the community...
