The role of herbivores and productivity on community structure of rocky shores of the Galapagos Islands, Ecuador

Creator:: Vinueza, Luis R.
Abstract:: Ecosystems are facing increasing threats from human related activities, such as overfishing, pollution, habitat destruction, species invasions, and diseases, among others. While oceanic islands provide natural laboratories to understand ecological and evolutionary process, they are also particularly vulnerable to these impacts, given their usual isolation from the mainland and the...

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...

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...

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...

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...

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...

The effects of parasites on host behavior : who benefits?

Creator:: Lefcort, Hugh G.
Abstract:: Some parasites may modify the behavior of their hosts. Altered behaviors may: 1) benefit the host in that they defend against the pathogen, 2) benefit the pathogen and represent manipulations of the host response, and 3) benefit neither the host or the pathogen and simply be a product of the...

A comparative analysis of morphological, physiological, and biochemical adaptation to abiotic stress in intertidal porcelain crabs, genus Petrolisthes

Creator:: Stillman, Jonathon Harris
Abstract:: Organismal tolerance to abiotic environmental stresses contributes significantly to setting the distribution limits of organisms, as demonstrated by vertical zonation patterns in the marine intertidal zone. In this thesis, the ultimate (evolutionary) and proximate (mechanistic) causes of tolerance to temperature and emersion stresses associated with the intertidal zone were examined...

Advancing marine reserve science : from field experiments to marine conservation planning tools

Creator:: Leslie, Heather M.
Abstract:: This dissertation focuses on science relevant to the design and implementation of marine reserves. The chapters explore a range of topics related to among-site variation in population, community, and ecosystem dynamics. My results demonstrate the value and feasibility of integrating this knowledge into more comprehensive conservation and management approaches. While...

Neural regulation of immunity in teleosts

Creator:: Flory, Craig M.
Abstract:: It has long been observed that stress can increase our susceptibility to infectious diseases and cancers. Recent experimental evidence suggests that this increased susceptibility is due to suppression of immunity. A variety of neuroendocrine products are released during periods of stress, and a large number of these are now known...
