Onset of symbiosis in a cnidarian-dinoflagellate association

Creator:: deBoer, Melissa L.
Abstract:: Scleractinian corals, like many other cnidarians, engage in intracellular symbiosis with dinoflagellates belonging to the genus Symbiodinium. This association makes invaluable structural and energetic contributions to the marine environment and to the coral reef ecosystem in particular. While many aspects of the cnidarian-dinoflagellate relationship have been well studied, nothing is...

Cost to Biomphalaria glabrata of Resisting Infection by Schistosoma mansoni

Creator:: Sergi, Clint
Abstract:: Schistosomiasis is a neglected tropical disease caused by parasitic trematodes in the genus Schistosoma. 200 million people are infected with schistosomes. Schistosomiasis causes acute and chronic disease, and may lead to death in chronic infections. Schistosomes have a complex life cycle that requires passage through a snail intermediate host. Understanding...

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...

Phenotypic evolution as a response to thermal ecology in the ferocious waterbug Abedus herberti (Hemiptera: Belostomatidae)

Creator:: Pelegrin, Arthur Lomis
Abstract:: Over 150 years ago, C. Bergmann observed a within-species pattern of increasing body size as elevation and latitude increased. Bergmann’s data came from numerous endothermic taxa, but the pattern has since been documented among numerous poikilotherms and invertebrates. The ferocious waterbug Abedus herberti Hidalgo (Hemiptera: Belostomatidae) lives in isolated populations...

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....

Singing behavior of the Bewick's wren : development, dialects, population structure, and geographical variation

Creator:: Kroodsma, Donald E.
Abstract:: The songs of the Bewick's Wren are discrete units of one to three seconds duration with intersong intervals several times the length of the song. Individual song repertoires at the William Finley National Wildlife Refuge, Oregon, range from 13 to 20 song types, and a given song type is repeated...

Invasive Pacific Lionfish Alters Native Community Interactions on Atlantic Coral Reefs

Creator:: Kindinger, Tye L.
Abstract:: Biological invasions have been identified as one of the prominent drivers of global environmental change. In particular, invasive predators typically have substantial negative effects on populations of native prey, even driving species to extinction in extreme cases. However, beyond direct predatory effects, little is understood regarding the specific mechanisms by...

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...

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...

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...
