OSU Marine Team: Long-term sampling of ichthyofauna in Yaquina Bay

Creator:: Gallagher, Brett, Heppell, Scott, and Heppell, Selina
Abstract:: Marine Team is a student effort to examine spatial and temporal variation of fish species within Yaquina Bay. Marine Team was developed at OSU as a seminar course with a field sampling component, to help students of marine ecology get “hands on” experience with data collection and analysis. We set...

Identification of Burrowing Shrimp Food Sources Along an Estuarine Gradient Using Fatty Acid Analysis and Stable Isotope Ratios

Creator:: Bosley, Katelyn M., Copeman, Louise A., Dumbauld, Brett R., and Bosley, Keith L.
Abstract:: Two species of burrowing shrimp occur in high densities in US West Coast estuaries, the ghost shrimp, Neotrypaea californiensis, and the blue mud shrimp, Upogebia pugettensis. Both species of shrimp are considered ecosystem engineers as they bioturbate and irrigate extensive galleries within the sediment. While their burrows comprise a dominant...

The Genetics of Larval Fitness in the Pacific Oyster: Responses to Acidified Seawater and Temporally Dynamic Selection Processes

Creator:: Durland, Evan R.
Abstract:: The Pacific Oyster (Crassostrea gigas) is one of the most economically and ecologically significant shellfish species worldwide. In the Pacific Northwest United States (PNW), the sustainability oyster stocks is increasingly threatened by ocean acidification (OA), which has had significant negative effects on the aquaculture industry in this region over the...

An introduced Asian parasite threatens northeastern Pacific estuarine ecosystems

Creator:: Chapman, John W., Dumbauld, Brett R., Itani, Gyo, and Markham, John C.
Abstract:: The introduced Asian parasitic bopyrid isopod, Orthione griffenis, was first discovered on the Pacific coast of North America in Washington in 1988 and next in California in 1992. The range of Orthione presently extends from British Columbia to Baja California, where it infests at least two species of the native...

Marine Heatwaves Influence Depth Preferences of Chinook Salmon (Oncorhynchus tshawytscha)

Creator:: Teahan, Andrew
Abstract:: Marine heatwaves have become more common over the past several years. The 2014-2015 ‘warm blob’ had profound effects on marine ecosystems in the Northeast Pacific. Given the particular habitat needs of Chinook Salmon (Oncorhynchus tshawytscha) we wanted to examine the impacts of the heatwave on Chinook depth distribution. We examined...

Comparing Metacarcinus magister settlement preferences among the seagrasses Z. marina and Z. japonica

Creator:: Jaco, Erin M. and Heidmann, Sarah
Abstract:: Metacarcinus magister, the Dungeness crab, is a commercially important species on the Pacific Northwest coast as the most profitable fishery in Oregon and an important ecological player as both predator and prey. Understanding the spatial distribution of Dungeness throughout different life history stages is beneficial both ecologically and economically. Zostera...

Growth and behavioral responses to elevated temperatures by juvenile sablefish Anoplopoma fimbria and the interactive role of food availability

Creator:: Sogard, Susan M. and Olla, Bori L.
Abstract:: Larval and age-0 sablefish Anoplopoma fimbria reside in neustonic waters of the North Pacific during spring and summer. We estimated the potential impacts of elevated surface temperatures on ecological processes of growth, conversion efficiency, and behavior in early juvenile sablefish. Growth experiments tested a wide range of temperatures from 6...

Food deprivation affects vertical distribution and activity of a marine fish in a thermal gradient: potential energy-conserving mechanisms

Creator:: Sogard, Susan M. and Olla, Bori L.
Abstract:: The effects of reduced food availability on the behavior of juvenile walleye pollock Theragra chalcogramma were examined in laboratory experiments designed to test for potential energy-conserving responses. Groups of juvenile fish were held on 1 of 6 ration treatments ranging from ad libitum to near starvation, and then vertical distribution...

Ecology and Distribution of Blue Whales in New Zealand Across Spatial and Temporal Scales

Creator:: Barlow, Dawn R.
Abstract:: The distribution of mobile marine predators often reflects underlying dynamic ecological processes. The geographical focus of this PhD is the South Taranaki Bight (STB) of New Zealand, where wind-driven coastal upwelling generates productivity and prey to support a blue whale foraging ground. The STB is also New Zealand’s most industrial...

The divergent effect of capture depth and associated barotrauma on post-recompression survival of canary (Sebastes pinniger) and yelloweye rockfish (S. ruberrimus)

Creator:: Hannah, Robert W., Rankin, Polly S., and Blume, Matthew T. O.
Abstract:: We evaluated the external signs of barotrauma and 48-h post-recompression survival for 17 54 canary and 81 yelloweye rockfish captured at depths of 46-174 m, much deeper than a 18 similar prior experiment, but within the depth range of recreational fishery catch and 19 discard. Survival was measured using specialized...
