Lamprey of the Goose Lake Basin: A Multi-Scale Habitat & Distribution Analysis

Creator:: Dickey, Jacob C.
Abstract:: Two ecologically important lamprey species found in the endorheic Goose Lake Basin face conservation threats; however, relatively little is known about their habitat needs or spatial distribution. Lamprey and their habitat are often found to be patchy; to evaluate these relationships for the lamprey in this basin, I utilized a...

Diving into Diversity: Fish Populations and Climate Resilience in an Endorheic Basin

Creator:: Dew, Aleah
Abstract:: The Goose Lake Basin, situated on the border of Oregon and California, USA, faces significant challenges from drought, wildfire, and other environmental stressors. This region hosts numerous endemic fish species such as the Goose Lake redband trout (Oncorhynchus mykiss newberri), Goose Lake lamprey (Entosphenus sp.), Goose Lake tui chub (Siphateles...

Development and Evaluation of a Static Land-Based Aquaculture System for Pacific Dulse (Devaleraea mollis): Environmental and Nutrient Requirements

Creator:: Chatfield, Marcus W.
Abstract:: Devaleraea mollis (Pacific Dulse) is becoming a popular food for human consumption. Previously, Pacific Dulse has been used as a nutrient source for cultured abalone species, with some historical food use by indigenous peoples, while the closely related Atlantic dulse (Palmaria palmata) has a long-documented history of use in cuisine...

Juvenile Salmonid Rearing Potential in Seasonally Disconnected Floodplain Habitats in the Skagit River, WA

Creator:: Hicks, Madeline C.
Abstract:: Our understanding of seasonally disconnected floodplains and how they function to support rearing salmonids in the Pacific Northwest is limited. Past studies have found that these dynamic habitats may provide high-risk, high-reward trade-offs for rearing fish. High prey densities and optimal temperatures allow for accelerated growth, but low water levels...

Modeling the habitat occupancy and abundance of salmonid ectoparasite Salmincola californiensis in Willamette Valley reservoirs

Creator:: Antonelli, Kelsi
Abstract:: The freshwater copepod Salmincola californiensis is an ectoparasite of Pacific salmonids (Oncorhynchus spp.) Threatened and endangered salmonids that rear in the reservoirs have been reported to experience higher rates of infection by S. californiensis than would be experienced by their stream-reared counterparts. These high levels of infection can lead to...

How Nearshore Currents affect Larval Dispersal and Genetic Connectivity of China Rockfish (Sebastes nebulosus) Along Oregon and Washington Coasts

Creator:: Avila, Alexandra M.
Abstract:: Connectivity of fish populations is a crucial question for fisheries conservation and the development of spatial management plans. Both adult and larval movement define the extent and direction of ecological and evolutionary overlap between geographic regions and, therefore, how we define stocks for management purposes. Within that context, my work...

Prespawning Mortality of Fall Creek Willamette Chinook Salmon (Oncorhynchus tshawytscha): Evaluation of the Effects of a New Trap at the Adult Fish Collection Facility

Creator:: Carey, Katherine
Abstract:: Annual rates of prespawn mortality (PSM) in adult Chinook salmon (Oncorhynchus tshawytscha) trapped and transported upstream of dams in the Willamette River basin are high (often >40%) and could limit the ability to restore natural populations of spring Chinook salmon if not reduced. Improvements at the U.S. Army Corps of...

An Evaluation of the Effects of the Parasite Salmincola californiensis on At-Risk Chinook Salmon Populations

Creator:: Gardner, Ethan N.
Abstract:: Once abundant in their native range, Pacific salmon species (Oncorhynchus spp.) were widely distributed across the northern Pacific Rim from South Korea and Japan to the Sacramento River in California. Remaining populations are subject to population-level threats, including pathogens. The freshwater parasitic copepod Salmincola californiensis is associated with the reduced...

Relationship between Ascarophis Sp. (Nematoda: Cystidicolidae), Sturgeon Feeding Pit Density and Ghost Shrimp Burrowing Behavior

Creator:: Brockman, Joseph N.
Abstract:: Bioturbation caused by ghost shrimp, Neotrypaea californiensis, burrowing activity can negatively affect Pacific oyster, Crassostrea gigas, aquaculture through their burial and subsequent suffocation. The shellfish aquaculture industry used chemicals to control burrowing shrimp populations in Washington State estuaries for decades, but, due to public and governmental scrutiny, that practice has...

Assessing the Effects of Contemporary Forest Harvest on Headwater Stream Food Webs in the Oregon Coast Range

Creator:: Mowlds, Emilee A.
Abstract:: Food webs are fundamental in ecology, as they offer a way to better understand the interrelatedness, connectivity, and complexity within a given ecosystem. The use of network analysis to model food webs can provide insights about the importance of physical templates on the organization of biological systems in streams using...
