Intertidal Ecology along the Western Coastlines of the Pacific : Upwelling and Bottom-up Effects in Chile and Oregon

Creator:: Murphy, Christina A.
Abstract:: The coastal regions of Chile and Oregon are some of the most productive ecosystems in the world. The intertidal communities of both areas have been well studied, but much remains to be learned about how those communities are structured over large scales. Here, I explore the upwelling regimes and the...

Succession and stability in two rocky intertidal communities on the central Oregon coast

Creator:: Farrell, Terence M.
Abstract:: The stability of a limpet-dominated community was assessed in a experiment in which an consumer was temporarily removed. Compared to unmanipulated plots, the limpet-exclusion plots developed greater algal abundance and altered species composition of both algae and barnacles. The community was not perturbed beyond its capacity to recover, since the...

Patterns of age and growth in young-of-year rockfish, sebastes spp., along the Oregon coast

Creator:: Young, Thomas
Abstract:: Rockfish of the genus Sebastes are important components of Oregon reef communities. I examined patterns of age and growth in young-of-year rockfish across two nested spatial scales – local and regional – along the Oregon coast. Using otolith microstructural examination, I examined the relative importance of local versus regional factors...

So Long and Thanks for All the Sponge: Cryptic Intertidal Communities, Consequences of Ocean Acidification, and New Directions for Science Education

Creator:: Rickborn, Alissa J.
Abstract:: The current generation of scientists will be asked to mitigate climate change, stall biodiversity loss, and protect ecological communities. These are tasks that require a knowledge of both ecological and social systems to be undertaken successfully. Therefore, my dissertation spans the fields of community ecology and social sciences in an...

The effects of interspecies interactions and environmental conditions on biomass accumulation of sessile organisms within Oregon’s rocky mid-intertidal habitats

Creator:: Carsh, Alexander C.
Abstract:: With changing climate conditions and human impacts on ecosystems becoming a big focus of study, it has become even more crucial to understand how our ecosystems work. Community structure within rocky intertidal habitats is governed by a mix of environmental conditions and species interactions. This project examined the effects of...

The role of avian predators in an Oregon rocky intertidal community

Creator:: Marsh, Christopher P.
Abstract:: Birds affected the community structure of an Oregon rocky shore by preying upon mussels (Mytilus spp.) and limpets (Collisella spp.). The impact of such predation is potentially great, as mussels are the competitively dominant mid-intertidal space-occupiers, and limpets are important herbivores in this community. Prey selection by birds reflects differences...

Effects of ocean acidification on growth rate, calcified tissue, and behavior of the juvenile ochre sea star, Pisaster ochraceus

Creator:: Britsch, Melissa L.
Abstract:: Anthropogenically-induced increases in the acidity of the ocean have the potential to seriously harm marine calcifying organisms by decreasing the availability of carbonate (CO32−) used to make shells. I tested the effects of lowered pH on juvenile Pisaster ochraceus, an intertidal sea star and keystone predator in the eastern Pacific...

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...

Effects of Hypoxia on Survival and Growth of Barnacle Larvae Off the Oregon Coast

Creator:: Amstutz, Amanda C.
Abstract:: In recent years off the United States Oregon coast severe hypoxic events have resulted in areas of mass vertebrate and invertebrate species mortality known as dead zones. Creation of dead zones and alteration of community species composition in response to inner shelf hypoxic conditions have been observed annually from 2002...
