Functional Diversity : A Tool to Track Spatiotemporal Changes in the Trophic Organization of Reef Fish Assemblages

Creator:

Rincón Diaz, Martha P.

Abstract:

Biodiversity loss in highly diverse systems such as coral reefs has been linked to significant declines in the ecosystem functions and services provided by marine species. Ecological functioning of coral reefs and the resistance of coral reef fish communities to disturbance depend on the functional traits of species that promotes...

Dissertation
Movement Patterns of Rockfishes at the Redfish Rocks Marine Reserve, Oregon

Creator:

Calvanese, Thomas P.

Abstract:

The effects of Marine protected areas (MPAs) on adult fish populations depend on the degree of protection provided, which is partly a function of MPA size and the spatial extent of fish movements. The Redfish Rocks Marine Reserve (RRMR) and MPA, located on the south coast of Oregon near Port...

Modeled Larval Connectivity Patterns in two Coral Reef Regions : the Western Caribbean and the Kenyan-Tanzanian Shelf

Creator:

Mayorga Adame, Claudia Gabriela

Abstract:

Tropical coral reef ecosystems are very important from both the ecological and economical points of view. However, they are also particularly fragile, and have been declining in recent years in most regions of the world, since they are highly susceptible to anthropogenic stressors operating at global scales (e.g., global warming...

Informal Education on an Estuary Nature Trail : A Study of Visitor Knowledge, Attitudes and Behavior

Creator:

Osterman-Sussman, Irene

Abstract:

The Mark 0. Hatfield Marine Science Center (HMSC) public education opportunities include interpretive programs offered along the Estuary Nature Trail. The purpose of this study was to determine the effectiveness of three informal education programs, interpretive signs, a self-guided trail brochure, and guided naturalist walks, in imparting information on the...

Masters Thesis
Macroscale to local scale variation in rocky intertidal community structure and dynamics in relation to coastal upwelling

Creator:

Freidenburg, Tess L.

Abstract:

Understanding how large-scale processes (>100 kms) influence ecological communities is currently a major focus in ecology. In marine systems, coastal upwelling, a large-scale oceanographic process in which surface water pushed offshore by winds is replaced by cold, nutrient-rich water from depth, appears to cause variation in rocky intertidal communities. Along...

Dissertation
Feeding behavior and diet of native bull trout Salvelinus confluentus and introduced brook trout S. fontinalis in two Eastern Oregon streams

Creator:

Gunckel, Stephanie L.

Abstract:

One of the greatest threats to native bull trout Salvelinus confluentus populations is the presence of non-native brook trout S. fontinalis. This study, conducted in two second-order Eastern Oregon streams, investigates the effect of brook trout on the feeding behavior arid diet of bull trout. Feeding behavior, microhabitat use, and...

Masters Thesis
Description and analysis of dietary preference of lingcod in the nearshore zone, Oregon

Creator:

Tinus, Craig A.

Abstract:

The lingcod (Ophiodon elongatus) is an important groundfish species in both recreational and commercial fisheries of the Northeastern Pacific. It is a large, fast-growing, generalist predator of invertebrates and fishes. In response to concerns that lingcod may limit populations of rockfishes (Sebastes spp.), I compared the diets of 375 adult...

Influence of streamflow regime and biotic interactions on fish assemblage structure in rivers of the northern Great Plains

Creator:

Kelly, Valerie

Abstract:

This study evaluates the functional organization of stream fish assemblages in response to streamflow factors and biotic interactions across a range of spatial scale. The study area for this project includes 109 stream reaches located on tributaries to the upper Missouri River in the northern Great Plains. Fish distribution data...

Dissertation
Marine protected areas : Gathering stakeholder input via an internet-based survey

Creator:

Demirdjian, Renee

Abstract:

Conservation efforts have been increasing in recent years to help preserve threatened coastal and ocean resources. Marine protected areas (MPAs) are an important tool to protect and conserve ocean resources. The MPA Center was established to take the lead in developing a framework for a national system of MPAs. The...
