Tidal channel diatom assemblages reflect within wetland environmental conditions and land use at multiple scales - Weilhoefer, Christine L.; Nelson, Walter G.; Patrick J Clinton (Estuaries and Coasts, 2015)
The authors examined diatom assemblages collected from surface sediment in tidal channels of 47 tidal wetlands on the Oregon coast during the summer of 2007. They found some interesting and enlightening differences between the different groups of diatom species collected. “The tidal channel benthic diatom community was most strongly correlated with variables related to human disturbance at all scales surrounding the wetland and not with any tidal channel water quality parameter, including salinity. . . The sensitivity of the tidal creek benthic diatom assemblage to both wetland and landscape level factors indicates that it might be a useful bioindicator of human disturbance to tidal wetland ecosystems.” (from the Abstract)

Whitewater boater and angler conflict, crowding and satisfaction on the North Umpqua River, Oregon - Kainzinger, Silvia; Burns, Robert C.; Arnberger, Arne (Human Dimensions of Wildlife: An International Journal, 2015)
In 1992, “a zoning approach with voluntary restrictions for certain hours of the day and certain seasons of the year was implemented” on the North Umpqua River for recreational users of the river (p.543). Was this enough to prevent confluct between the various groups that used the river? Could whitewater boaters, fly fishers and salmon fishers get along? If there were confluct between user groups, did that conflict affect the satisfaction users experienced? “As reported crowding levels were very low for both boaters and anglers, we posit there is little need for managerial attention. At the current time the management approach of spatial zoning and river floating guidelines is working to prevent in- and outgroup conflict between boaters and anglers.” (p.550)

Assessment of the Vulnerability of Oregon and Washington's Natural Areas to Climate Change - Massie, Margaret H. (Oregon State University, 2014)
Master's thesis. The author examined natural areas in Oregon and Washington that are managed by a variety of Federal and State agencies. Were these areas representative enough of the variety of landscapes in the region that they would serve as good monitoring sites for evaluating the effects of climate change? If so, which sites would have the best potential for detecting change over the long term? She then applied climate models to these areas and showed a growth in warmer forests and a decline in the cooler forest types. By 2050, for example, the climate is predicted to have become changed in suitability for approximately 50% of the vegetation currently on Cascade Head, and 100% changed in suitability for vegetation at Cougar Creek, Lost Creek and Martin Creek Natural Areas on the Umpqua River. (p.69) The major professor was Anita Morzillo.

Fate and behavior of rotenone in Diamond Lake, Oregon, USA following invasive tui chub eradication - Finlayson, Brian J.; Eilers, Joseph M.; Huchko, Holly A. (Environmental Toxicology and Chemistry, 2014)
Diamond Lake experienced an invasion of tui chub in the 1940s, which eventually forced the Oregon State Game Commission to kill all the fish in the lake in 1954 by applying rotenone. By 1992, the tui chub was back, probably due to being used as live bait. The reintroduction of the invader damaged water quality, killed aquatic invertebrates, and caused toxic blooms of cyanobacteria. By 2006, another rotenone fish-kill was planned. This time, the EPA required monitoring to make sure neither rotenone nor rotenolone, a compound produced by the breakdown of rotenone, were introduced in harmful amounts into nearby wells or streams. This article discusses the rotenone treatment, its monitoring and makes recommendations for future managers facing this situation.

Indicators of Social Vulnerability in Fishing Communities along the West Coast Region of the U.S. - Miller, Stacey D. (Oregon State University, 2014)
This is a final essay by a candidate for a Master’s degree in Public Policy. The author examined Pacific Northwest coastal communities in order to determine which were economically dependent on the fishing industry and might, therefore, be vulnerable to changes in fishing policies and regulations. “Place-based data from the U.S. decennial census, American Community Survey, NOAA Fisheries, state fish and wildlife agencies, and a myriad of additional sources are included in a factor analysis to identify communities engaged in and reliant on commercial fishing, and to derive indicators of social vulnerability. Using these indicators, 18 communities along the west coast were identified as having high levels of both commercial fishing dependence and social vulnerability, although the drivers varied among communities.” (from the abstract) Major professor was Denise Lach.

Invasive crayfish as vectors of mercury in freshwater food webs of the Pacific Northwest - Johnson, Branden L.; Willacker, James J.; Eagles-Smith, Collin A.; Pearl, Christopher A.; Adams, Michael J. (Environmental Toxicology and Chemistry, 2014)
Crayfish are important participants in food webs – they eat a lot, and in turn are important prey for many creatures. This is an interesting look at crayfish uptake of mercury in aquatic environments in western Oregon. The authors compare the native signal crayfish with the introduced ringed crayfish and the introduced red swamp crayfish. Interestingly, members of the native species seem to have the highest concentrations of mercury in their tissues. Also, “Crayfish from the Umpqua watershed had the highest overall [total mercury] THg concentrations, exceeding those in both the Rogue …and Willamette watersheds.” (p.2641) The authors note the Bonanza Mine in the Umpqua watershed, as well as a recent increase in gold mining dredging which may have stirred up mercury-tainted sediments as possible contributing factors.

Linking landscape characteristics and high stream nitrogen in the Oregon Coast Range: red alder complicates use of nutrient criteria - Greathouse, Effie A.; Compton, Jana E.; Van Sickle, John (Journal of the American Water Resources Association, 2014)
Red alder fixes nitrogen, and in the fall and winter it sheds nitrogen into coastal streams. The result is that many coastal streams have at certain times of the year nitrogen levels that are unacceptably high, according to conventional environmental standards. Current nutrient models for Oregon coast streams fail to adequately account for this natural process. “Our results provide evidence, at a regional scale, that background sources and processes cause many Coast Range streams to exceed proposed nutrient criteria, and that the prevalence of a single tree species (N-fixing red alder) exerts a dominant control over stream N concentrations across this region.” (from the Abstract)

Movements, habitat use, and population characteristics of adult Pacific lamprey in a coastal river - Starcevich , Steven J.; Gunckel, Stephanie L.; Jacobs, Steven E. (Environmental Biology of Fishes, 2014)
Before they spawn, mature Pacific lamprey spend about a year in freshwater. What they do during that year was investigated in this study, which used radio-telemetry and followed tagged fishes. Distinct behavior and migration patterns were observed. Interestingly, some lamprey spawned in multiple locations, separated by as much as 16 kilometers, and with multiple spawners.

Nursery Functions of U.S. West Coast Estuaries: The State of Knowledge for Juveniles of Focal Invertebrate and Fish Species - Hughes, Brent B.; Levey, Matthew D.; Brown, Jennifer A.; Fountain, Monique C.; Carlisle, Aaron B.; Litvin, Steven Y.; Greene, Correigh M.; Heady, Walter N.; Gleason, Mary G. (The Nature Conservancy, 2014)
This report summarizes what is known about the role of estuaries as nurseries for important aquatic species. The authors inventoried 303 West Coast estuaries and categorized each by class (lagoonal, riverine, embayment and sound) and subclass (estuarine coastal subtidal, tidal channel/creek, slough and lagoon). They examined 15 different species that used estuaries and noted what is known and not known about their life cycles and use of estuaries. “Together with the estuary inventory and the geodatabase, this report represents the first stage in a larger effort to better understand the nursery functions of West Coast estuaries for fish and invertebrates.” (p.3)

Post-Mazama river terraces and human occupation along the North Umpqua River Oregon - Freidel, Dorothy E.; O’Neill, Brian L. (Human Environment Interactions – Volume 2: Reconstructing the Natural and Anthropogenic Landscape, 2014)
About 7,600 years ago, Mount Mazama exploded in a massive volcanic eruption which led to the formation of Crater Lake. The eruption reshaped the surrounding environment in profound ways. Huge quantities of glowing pyroclastic debris were laid down, and for a time the area was uninhabitable. This publication looks at changes on the North Umpqua River that caused a series of terraces to be formed. The streamside terraces consist of original ash deposits as well as re-worked and re-deposited ash, and more recent floodplain deposits. There is evidence that humans were back in the North Umpqua area within a few hundred years of the eruption. Subsequent events such as a change in climate also affected human occupation of the area. If you are interested in the geology, geography and archeology of the region, this book chapter is a valuable find.

Recovery of Oregon Coast Coho Salmon (Onchorhynchus kitsutch) through Restoration of Freshwater Habitats - Lutz, Andrew P. (University of San Francisco, 2014)
Millions of dollars have been spent in enhancing habitats to aid recovering populations of salmon on the Oregon Coast. How well have enhancement projects done? Does there seem to be a relationship between restoration projects and salmon recovery? The author addresses these questions. ”My analysis showed that from 1994 to 2012 only 3 of the 21 independent populations from the ESU, the Alsea, Salmon, and Tillamook had statistically significant recovery. To evaluate the relationship between habitat restoration and coho recovery, I ran a correlation between the rate of recovery and the amount spent on restoration for each ESU population. The rate of recovery increased as total dollars spent on restoration increased, but it was a very weak relationship…” (from the Abstract) The author concludes by suggesting ways to improve restoration efforts.

On the reproductive success of early-generation hatchery fish in the wild - Christie, Mark R.; Ford, Michael J.; Blouin, Michael S. (Evolutionary Applications, 2014)
This is a review of several studies of the relative reproductive success of wild and hatchery salmonids. It is another nail in the coffin for fish hatcheries. “Our analyses clearly show that even hatcheries using local- and predominately wild-origin broodstocks create fish with lower reproductive success than their wild-born counterparts… The reduced fitness of hatchery fish was consistently documented despite differences in geographic location, study species, hatchery practices and analytical approaches.” (p.894) Among the studies referenced was Thériault’s case study of Umpqua River coho salmon published in 2010 and 2011, and which may be found in this bibliography.

Responses of Juvenile Coho Salmon and Larval Lamprey to Instream Habitat Restoration in a Pacific Northwest Stream - Gonzalez, Rosalinda (Oregon State University, 2014)
Master’s thesis. This thesis takes an interesting look at the use of large woody debris in stream restoration by including non-salmonid species in the study, as well as coho salmon. While earlier studies did not find close correlations between large woody debris and coho salmon spawning habitat selection, this study offers “support for the general finding that large wood restoration can benefit juvenile Coho Salmon, but also larval lamprey in some geomorphic contexts.” One problem with woody debris is that it can wash away and not be replaced due to current forest management practices. The author suggests that “restoration of large wood in streams over longer time frames may be more tied to restoration of the process of wood recruitment and less on active placement of wood in streams.” (p.28) The major professor was Jason Dunham.

Tsunami impact to Washington and northern Oregon from segment ruptures on the southern Cascadia subduction zone - Priest, George R.; Zhang, Yinglong; Witter, Robert C.; Wang, Kelin; Goldfinger, Chris; Stimely, Laura L. (Natural Hazards, 2014)
All who live on the West Coast of the United States should be aware of the possibility of a major earthquake occurring. But what if only a part of the subduction zone ruptures? This article examines a possible rupture in the southern half of the Cascadia Subduction Zone (south of Alsea Bay, Oregon). The authors ask important questions. How quickly does tsunami wave height decline north of the southern rupture areas? How much time do communities north of the southern rupture areas have to evacuate before the first inundation and the largest inundation occur? How far north of the southern rupture areas will felt shaking likely trigger evacuation of a populace trained to evacuate for a local earthquake? (p.851) The authors address these questions using a 10,000-year record of offshore turbedite deposits and a ~4,600-year record of tsunami deposits at Bradley Lake.

Water quality and algal conditions in the North Umpqua River, Oregon, 1995–2007, and their response to Diamond Lake restoration: - Carpenter, Kurt D.; Anderson, Chauncey W.; Jones, Mikeal E. (U.S. Geological Survey Open-File Report, 2014)
“Prepared in cooperation with Douglas County and the U.S. Forest Service.” By the early 1990s, scientists were concerned about algal blooms in the North Umpqua River. Algal blooms in Diamond Lake and Lemolo Lake were possible sources of the problem. When plans were made to draw down Diamond Lake and re-set the food web by killing the invasive Tui chub, an opportunity was seen for looking at conditions in the North Umpqua River, in particular relating to algal blooms. The river was surveyed in 2005 before the drawdown, and in 2007, after Diamond Lake was restored. This report focuses on harmful algae blooms in the North Umpqua River, the causes of the blooms, and their effects on the ecosystem.

Adapting to climate change on the Oregon coast: lines in the sand and rolling easements - Johnson, Courtney B.; Schell, Steven R. (Journal of Environmental Law and Litigation, 2013)
In this important article, the authors argue that Oregon should be working to strengthen its laws now in order to have the flexibility and legal framework to enable it to adapt to a changing climate and sea level rise. “Processes are needed to decide what infrastructure will be replaced and what will not before these inevitable events occur. . . . Planning can ensure that shoreline armoring does not eliminate public access along the shore or total loss of sand on Oregon’s beaches. Planning tools can make clear that the public access boundary does migrate inland, even if the shoreline migrates onto an inland parcel across which the public does not currently have access.” (p.514)

Basin-Scale Variation in the Spatial Pattern of Fall Movement of Juvenile Coho Salmon in the West Fork Smith River, Oregon - Hance, Dalton J. (Oregon State University, 2013)
“For several species of Pacific salmon (Oncorhynchus spp.) inhabiting coastal temperate streams, juvenile fish have been recorded moving between mainstem and tributary habitats during the transition from the summer dry season to the winter wet season. Such movement that connects summer and winter habitats may be particularly important for coho salmon, O. kisutch, because availability of overwintering habitat can limit freshwater survival for this species. Here, I describe basin-scale variability in the spatial pattern of fall movement for juvenile coho salmon between mainstem and tributary streams during the fall of 2002, 2003, 2004, and 2005.” (from the Abstract) Includes maps of study sites. A most interesting study of the complexities of juvenile coho migration to find secure habit for overwintering. The major professors were Lisa M. Ganio and Kelly M. Burnett.

Breeding Site Selection by Coho Salmon (Oncorhynchus kisutch) in Relation to Large Wood Additions and Factors that Drive Reproductive Success - Clark, Steven (Steven Michael) (Oregon State University, 2013)
Where a female salmon decides to lay her eggs has a great deal to do with whether any of the eggs survive to eventually return to the spawning stream. This thesis looks at site selection to see what factors might influence the decision of where to spawn. Interestingly, placement of large woody debris in engineered logjams did not seem to positively influence spawning site location. Jason B. Dunham was the major professor.

Cost-Efficient Management of Aquatic Invasive Species: Application to New Zealand Mudsnails in the Pacific Northwest - Lim, Youngah (Oregon State University, 2013)
The New Zealand mud snail, a destructive invasive species, has been found in the Wilson, Trask, Nestucca, Siletz, Yaquina, Alsea, Siuslaw, Umpqua and Coos Rivers. Based on the animal’s biology, Siltcoos Lake is threatened. The snail is a bio-fouling organism that blocks water intake pipes, and threatens aquatic industries and tools from boat motors to hydroelectric plants. In this dissertation, the author assesses possible ways of managing this invasion, and assesses the costs of different management strategies. Major professor was Munisamy Gopinath.

Distribution of Juvenile Salmonids and Stream Habitat Relative to 15-Year-Old Debris-Flow Deposits in the Oregon Coast Range - Kirkby, Kristen-Marie S. (Oregon State University, 2013)
The severe weather and heavy rainfall of February, 1996 caused many landslides in the Oregon Coast Range. This study looks at the effects of landslides and debris flows on fish 15 years later. “My primary objectives in this study are to: 1) explore whether the abundance of juvenile coho salmon, age 0+ trout, and age 1+ trout in summer pools varies with distance to the nearest 15-year-old debris-flow deposit; and 2) examine pool habitat characteristics in 1996 and 2011 relative to distance to the nearest 15-year-old debris-flow deposit to document change and as possible explanations of observed salmonid distribution. “ (p.5) The major professor was Kelly M. Burnett.

Ecosystem components, protected species – salmon: Chinook and coho salmon - Wainwright, Thomas C.; Williams, Thomas H.; Fresh, Kurt L.; Wells, Brian K.; Levin, P.S.; Wells, B.K.; Sheer, M.B. (Integrated Ecosystem Assessment of the California Current. Phase II Report 2012., 2013)
The is a broad assessment of population trends for salmon populations in California, Oregon, Washington, and the Snake River salmon. Geographic areas are addressed broadly and data for specific streams is not delineated. In general, Oregon coast salmon populations were seen as having swings in abundance from year to year, but were broadly stable.

Effect of contemporary forest harvesting practices on headwater stream temperatures: Initial response of the Hinkle Creek catchment, Pacific Northwest, USA - Kibler, Kelly M.; Skaugset, Arne; Ganio, Lisa M.; Huso, Manuela M. (Forest Ecology and Management, 2013)
A really interesting look at the effects of clearcut logging on non-fish bearing headwater streams in the Umpqua River Basin. “The summer following harvesting, we observed a variable temperature response across the four harvested streams. Mean maximum daily stream temperatures ranged from 1.5 C cooler to 1.0 C warmer relative to pre-harvest years. We also observed significantly lower minimum and mean daily stream temperatures, and recorded particularly low temperatures in treatment streams on days that minimum stream temperatures in reference streams were high.” (from the Abstract) Slash residue from logging seems to have affected water temperatures in a surprising way.

Finding appropriate bias correction methods in downscaling precipitation for hydrologic impact studies over North America - Chen, Jie; Brissette,Francois; Chaumont, Diane; Braun, Marco (Water Resources Research, 2013)
This is a technical discussion of how hydrologic models can be improved by various statistical techniques. The authors ran raw regional climate model precipitation data with a hydrologic simulation, and then tried different methods of correcting input precipitation data for ten different North American rivers. It turns out that the Umpqua River raw regional climate model data worked well with the hydrologic model, and additional corrections were not needed for the simulation to approximate reality.

Geographic range and structure of cryptic genetic diversity among Pacific North American populations of the non-native amphipod Grandidierella japonica - Pilgrim, Erik M.; Blum, Michael J.; Reusser, Deborah A.; Lee II, Henry; Darling, John A. (Biological Invasions, 2013)
In this article, the authors attempt to reconstruct the invasion history of the introduced amphipod Gradidierella japonica. DNA analysis shows two distinct groups – one from San Francisco south, and the other north of San Francisco. There are significant genetic differences between the two groups, which, coupled with low genetic diversity within each group, suggests that there were two separate introductions of this species to the West Coast.

Geography of the circadian gene clock and photoperiodic response in western North American populations of the three-spined stickleback Gasterosteus aculeatus - O’Brien, C.; Unruh, L.; Zimmerman, C.; Bradshaw, W. E.; Holzapfel, C. M.; Cresko, W. A. (Journal of Fish Biology, 2013)
Many animals use the timing of day length to anticipate changes in their environments. Day length is closely linked to seasonal activities such as reproduction. This article describes a study of a specific gene, the clock gene, and looked at variations in length of the polyglutamine domain of the clock protein in the three-spined stickleback. Sticklebacks from widely varying latitudes (northern Alaska and southern Oregon) were examined to see if variations in length of the polyglutamine domain corresponded with different latitudes. The study found no significant variation in length, and photoperiodic responses were similar in the differing latitudes..

Natural and human impacts on centennial sediment accumulation patterns on the Umpqua River margin, Oregon - Wheatcroft, Robert A.; Goñi, Miguel A.; Richardson, Kristin N.; Borgeld, Jeffry C. (Marine Geology, 2013)
This article examines the recent history of sediment deposition off the mouth of the Umpqua River, and attempts to explain the observed deposits. The offshore deposit is defined and related to deposition at the mouths of the Columbia and Eel Rivers. There was a 2-to-4 times increase in the rate of sediment deposition in themed-1960s, which is related to increased logging from 1945 forward. Deposition is also related to regional climate factors, such as the Pacific Decadal Oscillation, and wave heights. Maps, charts and tables are included.

Reconnecting Aquatic Habitats: Validating Historical Habitat Use by Anadromous Fishes Using Telemetry and Stable Isotope Analysis above Barriers - Lewis, Sierra Koch (Oregon State University, 2013)
In November, 2012, PacifiCorp put in a fish ladder over Soda Springs Dam, which opened up new spawning habitat for anadromous salmonids on Fish Creek. The fish ladder was a relicensing requirement. In advance of this change, the author captured fourteen wild summer steelhead and relocated them into Fish Creek, on the blocked side of Soda Springs Dam, in order to study their movements and behavior in newly accessible habitat. From June, 2010 through late May, 2011, the trout were tracked using radio telemetry. “The main goal of this project was to provide management recommendations for habitat restoration projects upstream of the Soda Springs Dam and above a natural waterfall in the Fish Creek tributary on the North Umpqua River in Oregon.” (p.3) The author also used stable-isotope analysis to document historically salmon-derived nitrogen in the landscape from samples of Douglas fir trees. This study is an interesting first look at fish behavior in newly re-opened habitat. The major professor was David L. G. Noakes.

Relationships between Stream Discharge and Cutthroat Trout Abundance at Multiple Scales in Managed Headwater Basins of Western Oregon - Owens, Hazel L. (Oregon State University, 2013)
“Relationships between resident cutthroat trout (Oncorhynchus clarkii clarkii) and six hydrologic indices were investigated using correlation analysis in two experimental headwater catchments in the foothills of the Cascade Mountains of western Oregon. This investigation was to determine if characteristics of discharge explained inter-annual variability in trout abundance.” (from the Abstract) The author attempted to assess the role of spatial scale and stream network location to see how they affected the ability to detect relationships between streamflow and cutthroat trout abundance. She also explored ways to integrate spatial and temporal datasets in hydro-ecological studies. The major professor was Arne E. Skaugset.

Some Marine Algae on Tsunami Debris [poster] - Hansen, Gayle I. (Oregon State University. Dept. of Botany and Plant Pathology, 2013)
On March 11, 2011, the great Tōhoku earthquake shook Japan. The subsequent tsunami swept approximately 5 million tons of debris into the Pacific Ocean, some of which made its way across the Pacific and washed up on the North American West Coast. The debris carried hundreds of species, a surprising number of which survived the trip. In order to understand the potential for biological invasions, it was necessary to document these species. This poster documents some of the first algae identified. It is beautifully photographed.

Variation in the Timing of Coho Salmon (Oncorhynchus kisutch) Migration and Spawning Relative to River Discharge and Temperature - LovellFord, Rachel M. (Oregon State University, 2013)
This very interesting study examines different factors that induce salmon to begin their migrations towards spawning grounds. “This study compares interannual patterns in the timing of coho mid-river migration in the North Umpqua (180 km up river from the estuary) and the initiation of spawn timing in the Smith River basins (Oregon) with river discharge and water temperature data to ascertain whether these behaviors are driven by fluvial conditions. Additionally, we used this data to identify the window over which most migration and spawning takes place in our test systems.” (from the Abstract) The North Umpqua study used Winchester Dam passage data for 1998-2010. In the Smith River study, the author contrasted data from stream gauging stations at five locations in the basin with observations of run timing. The major professor was Mary V. Santelmann.

Estimating vertebrate, benthic macroinvertebrate, and diatom taxa richness in raftable Pacific Northwest rivers for bioassessment purposes - Hughes , Robert M.; Herlihy, Alan T.; Gerth, William J.; Pan, Yangdong (Environmental Monitoring and Assessment, 2012)
In order to assess the biological diversity (richness of taxa) in Western rivers, the authors sampled multiple, randomly selected sites for each river.. They looked at aquatic vertebrates, aquatic macroinvertebrates and diatoms to determine the number of different species per site the average richness of species per river, and the range of numbers of species per river. The authors attempt to answer the question of how many sites should be sampled in order to properly estimate the biological richness of a large river, and along the way give a snapshot of the current state of the Umpqua and other rivers.

Genetic Population Structure and Cryptic Speciation of Ghost Shrimp (Neotrypaea californiensis) in North American West Coast Estuaries - Gille, Daphne Anne (San Jose State University, 2012)
Surveyed the West Coast from Puget Sound to San Diego to study the genetics of the ghost shrimp population and thereby infer the potential for larval dispersal in ghost shrimp. “Multiple haplotypes were shared among 346 adult ghost shrimp specimens collected from estuaries in Washington, Oregon, and California indicated that larvae of this species are transported across great distances during the pelagic dispersal phase of development.” The author also found the population structure was influenced by “the presence of three putative cryptic species that were deeply divergent from N. californiensis.” (from the Abstract) Paper 4232.

Mate Choice of Wild Spawning Coho Salmon (Oncorhynchus kisutch) in the Umpqua River, Oregon - Whitcomb, Amelia C. (Oregon State University, 2012)
When hatchery-reared salmon spawn in the wild, there is evidence that they have less reproductive success than wild salmon. This study considers mate choice as a possible mechanism that contributes to greater or less reproductive success in salmonids. Wild-spawning coho salmon from the Umpqua River were examined in 2005 and 2006. “We tested for: (1) a departure from random expectations with regard to mate pair allelic diversity at immune-relevant markers, (2) a correlation between immune-relevant gene diversity and mate pair RS [reproductive success], and (3) distinguishable differences between mate choice strategies used by hatchery-reared and wild origin coho.” (from the Abstract)

Methylation of Hg downstream from the Bonanza Hg mine, Oregon - Gray, John E.; Hines, Mark E.; Krabbenhoft, David P.; Thoms, Bryn (Applied Geochemistry, 2012)
The Bonanza mercury mine operated from the late nineteenth century until 1960.In this study, stream sediments, stream water and aquatic snails were tested in order to learn the types of highly toxic mercury compounds found in waters downstream from the mine. Researchers were particularly interested in the presence of methylmercury, a water-soluble compound that is easily taken up by aquatic organisms. Researchers found elevated concentrations of mercury and methylmercury in Foster Creek, downstream from the Bonanza Mine. Due to other natural sources of mercury and other mines in the area, however, elevated mercury levels in fish throughout the watershed cannot be directly ascribed to the Bonanza Mine.

Non-wadeable river bioassessment: spatial variation of benthic diatom assemblages in Pacific Northwest rivers, USA - Pan, Yangdong; Hughes , Robert M.; Herlihy, Alan T.; Kaufmann, Philip R. (Hydrobiologia, 2012)
Most bioassessment is confined to small, wadable streams. This article discusses the importance of assessing larger streams, and assessment methods focusing on benthic diatom assemblages. Lowland streams are contrasted with mountanous streams, and differences between rivers east and west of the Cascade Mountains are noted. The Umpqua River had more mountainous characteristics, and had similarities to east-side streams. The authors note that, while high nutrient concentrations were found in the mainstem Umpqua River, they were diluted after the North Umpqua River joined the mainstem.

Umpqua/Eden revisited: notes on the archaeology and ethnohistory of a Lower Umpqua Indian village on the Central Oregon Coast - Minor, Rick; Whereat, Don; Greenspan, Ruth L. (Journal of Northwest Anthropology, 2012)
This article gives current information on the Umpqua/Eden site, one of the most extensively studied archeological sites on the Oregon Coast. This site, which goes as far back as approximately 3,000 years, covers a much larger area than had been previously thought. Earlier archeological techniques had under-represented fish remains. “Although largely overlooked in previous analyses of collections from the site, the 1994 Test Pit 4 excavation indicates that fish remains were a major constituent of the faunal assemblage from Umpqua/Eden, and may have been of greater importance than either mammals or birds.” (p.59) Gives a nice summary of historical sources on Lower Umpqua peoples.

Electronic tagging of green sturgeon reveals population structure and movement among estuaries - Lindley, Steven T.; Erickson, Daniel L.; Moser, Mary L.; Williams, Greg; Langness, Olaf P.; McCovey, Barry W., Jr.; Belchik, Michael; Vogel, Dave; Pinnix, William; Kelly, John T.; Heublein, Joseph C.; Klimley, A. Peter (Transactions of the American Fisheries Society, 2011)
Green sturgeon spawn in a limited number of streams on the West Coast, including the Columbia, Rogue and Klamath rivers. In this study, young sturgeon were tagged and followed to see where they went. After spawning, they migrate and use many Pacific Coast estuaries, including the Umpqua River. Heaviest sturgeon use on the Umpqua is in the summer with some autumn use. Most Umpqua River green sturgeon spawned in the Rogue and Klamath rivers, although two sturgeon from the Sacramento River were found in the Umpqua. The study points out that sturgeon can use a variety of habitats and that keeping different habitats usable is important for their survival.

Rangewide phylogeography and landscape genetics of the Western U.S. endemic frog Rana boylii (Ranidae): implications for the conservation of frogs and rivers - Lind, Amy J.; Spinks, Phillip Q.; Fellers, Gary M.; Sjaffer. H. Bradley (Conservation Genetics, 2011)
The foothill yellow-legged frog is a species with a declining population, and is listed as a Species of Special Concern in California. This paper looks at genetic analysis to identify distinct subpopulations. The Umpqua Basin population is interesting in that it is more closely related to California populations than to Oregon groups. The authors urge that genetic biodiversity be considered in conservation plans, and that unique populations be preserved.

Reduced reproductive success of hatchery coho salmon in the wild: insights into most likely mechanisms - Thériault, Véronique; Moyer, Gregory R.; Jackson, Laura S.; Blouin, Michael S.; Banks, Michael A. (Molecular Ecology, 2011)
Hatchery salmonids have been shown to have less reproductive success than wild salmonids. This phenomenon has been extensively documented in steelhead. In this paper, the authors examine a hatchery program on the North Umpqua River to see if hatchery coho salmon also are less successful at breeding. Mature coho are less successful, particularly males, although hatchery jack salmon were about as successful as wild jacks. Even the most up-to-date hatchery practices such as using wild brood stock and allowing mating by pairs of fish were not enough to overcome the disadvantage suffered by hatchery coho. Possible mechanisms for the lack of reproductive success in hatchery coho are explored.

Responses of foothill yellow-legged frog (Rana boylii) larvae to an introduced predator - Paoletti, David J.; Olson, Deanna H.; Blaustein, Andrew R. (Copeia., 2011)
The foothill yellow-legged frog, a native amphibian, has been reduced to 43% of its historical range, and is considered a "sensitive" species. As populations of the introduced predator, the smallmouth bass, have spread up Cow Creek, this frog has started to disappear. This article examines the natural defenses of the foothill yellow-legged frog, and the lack of defenses the species has for an introduced predator. Larval foothill yellow-legged frogs do not seem to recognize the smallmouth bass as a potential threat.

Streamflow response to climate as influenced by geology and elevation - Mayer, T. D.; Naman, S. W. (Journal of the American Water Resources Association, 2011)
Studied how warmer winter temperatures and less snowpack has affected streams in the Klamath River Basin. Compared Klamath Basin streams with other rivers, including those in the Umpqua Basin. Distinguishes between surface-dominated rain basins such as the Umpqua River and Steamboat Creek, surface-dominated snowmelt basins, such as Deschutes River tributaries, and groundwater-dominated basins such as the North Umpqua River. Notes that for groundwater dominated streams, "Our results indicate that absolute decreases in July-September base flows are significantly greater, by an order of magnitude or more, in groundwater basins compared to surface-dominated basins." The authors point out that local geology must be considered when evaluating how streamflows are affected by climate change.

A Terrestrial Organic Matter Depocenter on a High-Energy Margin Adjacent to a Low-Sediment-Yield River: the Umpqua River Margin, Oregon - Hastings, Roxanne H. (Oregon State University, 2011)
What happens when sediments from the Umpqua River are deposited in the ocean? The answer to this question for the Umpqua and other rivers is important to understanding the global carbon cycle. Although the author of this thesis thought at first that the Umpqua's sediments would be widely dispersed by ocean action, she learned that instead, they are concentrated in one location, which she terms "a mid-shelf depocenter." Despite the energies of ocean tides and currents, this area is not swept clean, and sediments continue to accumulate. The author finds evidence that "suggests that other low-sediment-yield rivers may also create depocenters." (p.47)

"Over the past several decades the distribution of Umpqua chub has contracted such that there are now six fragmented populations. Because there is little information on the biology of Umpqua chub and concern has been raised about their ability to persist in the presence of smallmouth bass, we began a collaborative effort to better understand their demographics and genetics." In 2008, the authros took 25 specimens from each of the sic isolated populations for genetic analysis, and repeated the procedure in 2010 "for potential future analysis." (p.2) "USFWS Grant # E-2-54"

The close proximity of the continental shelf benthos to the productive surface ocean means that this flux is likely to be essential for maintaining ecosystem micronutrient supply."

Early Detection of a New Invasive Mesogastropod, Assiminea parasitologica, in Pacific Northwest Estuaries - Laferriere, Alix M.; Harris, Heidi; Schaefer, John; South Slough National Estuarine Research Reserve,; The Confederated Tribes of the Coos Lower Umpqua and Siuslaw Indians (2010)
"Assiminea parasitologica is a small intertidal estuarine mesogastropod snail native to Japan. This species was first documented in the Coos Bay Estuary, Oregon in June of 2007." Because the new species might create problems for native snails, a study was started in 2008. Baseline data was gathered on the new species, native gastropods Angustassiminea californica and Littorina subrotundata and another invasive snail, Myosotella myosotis. "The primary goal of the study was to obtain a current (2009) snap shot of the status of Assiminea parasitologica in Pacific Northwest Estuaries." (from the Executive Summary) Colored maps show where the invader was found. Along with the final report is an interactive .pdf map showing the distribution of A. parasitologica in Coos Bay.

Modelling physico-chemical factors affecting occurrences of a non-indigenous planktonic copepod in northeast Pacific estuaries - Cordell, Jeffery R.; Tear, Lucinda M.; Bollens, Stephen M. (Biological Invasions, 2010)
The invasive copepod Pseudodiaptomus inopinus has become established from the Coquille River in Oregon to the Chehalis River in Washington. Although the species was introduced before 1992, it had not spread beyond its 1992 distribution by 2004, indicating that it might have reached "a distributional limit." By characterizing estuaries with and without this copepod, it might be possible to identify estuaries vulnerable to future invasions. Salinity and stratification of water column temperature seem to be good predictors. The authors also identified several estuaries that might be vulnerable to this particular invader.

Is the Past Present? Historical Splash-Dam Mapping and Stream Disturbance Detection in the Oregon Coastal Province - Miller, Rebecca R. (Oregon State University, 2010)
"Severe scouring from splash damming was one of the earliest reported forms of widespread anthropogenic disturbance in streams of the Pacific Northwest, USA. Splash damming was a common method of log transport in western Oregon from the 1880s through the 1950s. Before being released in large freshets to downstream lumber mills, water and logs were stored in reservoirs behind splash dams." (from abstract) The author located known splash dams in the Oregon Coast region and comments on their lasting ecosystem effects, noting that an understanding of the history of human use of a stream is necessary in order to accurately evaluate present conditions. Detailed work was done on Camp Creek in the Umpqua Basin, the East Fork of the Millicoma River, and the East Fork of the Coquille River. Colored maps, colored photographs. Includes an interview with a splash-dam tender. Major professors were Joseph L. Ebersole and Kelly M. Burnett.

A Status Assessment of the Double-Crested Cormorant (Phalacrocorax auritus) in Western North America: 1998-2009 - Adkins, Jessica Y.; Roby, Daniel D.; U.S. Geological Survey. Oregon Cooperative Fish and Wildlife Research Unit,; Oregon State University (2010)
"Based on the best available data for the three Pacific coastal states and British Columbia during the periods ca. 1992 ... and ca. 2009, our best estimate of the average annual population growth rate (λ) for this population is 1.03, indicating that the population has grown at an average annual rate of about 3% per year over the last two decades. This overall trend apparently reflects continued recovery of the Western Population due to various statutory and ecological factors during the latter half of the 20th Century, including inclusion of the species in the Migratory Bird Treaty Act, the banning of DDT, and the shift by the species toward increased use of artificial nesting habitats. Most of this population increase, however, can be attributed to increases in the numbers of breeding pairs in the Columbia River estuary and at a few inland sites, which currently account for approximately 41% and 29% of breeding pairs in the Western Population, respectively. Concurrently, numbers of breeding pairs in coastal British Columbia, northern Washington, and southern California have declined since 1987-1992." (from the Executive Summary)

Studied survival of overwintering coho salmon smolts in the West Fork of the Smith River. "Current habitat conditions in the main-stem West Fork Smith River, which is characterized by exposed bedrock channels with low habitat complexity, appear to limit coho salmon production to a few (but large) smolts. Improved overwinter survival in the main-stem West Fork Smith River could provide substantial benefits to coho salmon populations, although the challenges are substantial and costs are high due to the legacy of past management."

Patterns of Natural Selection and Demography in Coastal Oregon Coho Salmon (Oncorhynchus kisutch) Populations: Evidence from Neutral and Olfactory Receptor Gene-Linked Markers - Johnson, Marc Aaron (Oregon State University, 2009)
"For Pacific salmon, the evolution of local adaptations depends upon the species’ propensity to return, or “home”, to natal streams at time of reproduction. Pacific salmon use olfactory cues to guide homing behavior, yet little is known about the genetics of olfaction in salmon. In this study, I use putatively neutral microsatellite markers to estimate demographic parameters and describe the population genetic structure of Oregon Coastal coho salmon (Oncorhynchus kisutch). . . I then used genomic sequence data from nine species of salmon and trout to infer the evolutionary history for eight olfactory receptor genes. . . Finally, I used molecular markers linked to olfactory receptor genes to test for a signal of selection among coho salmon populations from different rivers." (from the Abstract) Found the Coos Bay salmon were the major source of straying in the south coast, while Nehalem River salmon did most of the straying on the north coast. Major professor was Michael A. Banks.

Smith River steelhead and coho monitoring verification study, 2007 - Constable, Ronald J.; Suring, Erik J. (Monitoring Program Report (Oregon Plan for Salmon and Watersheds), 2009)
Surveyed juvenile salmonids in the Smith River, a tributary of the Umpqua River. Used electrofishing and snorkel surveys to estimate juvenile salmonid abundance and compared the accuracy of the two methods. In sites where both surveys were conducted both methods worked equally well for coho, but electrofishing estimates were higher for steelhead. Either method used alone is likely to lead to underestimating adult populations.

Habitat selection influences sex distribution, morphology, tissue biochemistry, and parasite load of juvenile coho salmon in the West Fork Smith River, Oregon - Rodnick, Kenneth J.; St.-Hilaire, Sophie; Battiprolu, Pavan K.; Seiler, Steven M.; Kent, Michael L.; Powell, Madison S.; Ebersole, Joseph L. (Transactions of the American Fisheries Society, 2008)
Surveyed juvenile coho salmon in the summers of 2004-2005 in the West Fork of the Smith River. Females preferred upper, cooler waters, while males tended to congregate in the warmer lower reach. Females tended to be more robust and better endurance swimmers. Both groups had heavy parasite burdens. "We show for the first time that there are sex differences in habitat distribution and the endurance swimming ability of juvenile coho salmon.

Macroinvertebrate Report: Oregon Coast Coho Evolutionarily Significant Unit (2006-2007): Final Report - Hubler, Shannon; Oregon. Dept. of Environmental Quality. Laboratory and Environmental Assessment Division,; Oregon Watershed Enhancement Board, (Oregon. Dept. of Environmental Quality. Laboratory and Environmental Assessment Division,, 2008)
One way to measure a stream’s health is to count the aquatic insects in it. “This report summarizes macroinvertebrate data collected in cooperation with the ODFW in the twenty-one independent coho populations units from 2006-2007. These data were collected by ODFW crews and analyzed by ODEQ staff. Biological integrity, temperature stress and fine sediment stress were evaluated for each of the twenty-one population units.” (p.4) There are good data here.

Mobility statistics and automated hazard mapping for debris flows and rock avalanches - Griswold, Julia P.; Iverson, Richard M. (Scientific Investigations Report (U.S. Geological Survey), 2008)
“Revised April 24, 2014.” This publication discusses use of a computer program originally designed to predict damage from volcanic lahar debris flows. In this case, the program is modified for areas that are susceptible to precipitation-induced mud or debris flows. The Scottsburg area was chosen as a test site. “In the south-central Oregon Coast Range, … the town of Scottsburg and the Rock Creek-Hubbard Creek watershed … in southern Douglas County, Oregon, became infamous when two debris flows caused five fatalities between November 17 and 19, 1996. The deaths were the result of debris flows inundating a home, overtaking a pedestrian, and pushing a car off the road…” (p.22) It is good to know that this work was done, and the criteria for debris flows starting (steepness of slope and area of steep slopes) are interesting.

The Oregon Coastal Subprovince, a New Biogeographic Subprovince for Primary Freshwater Fishes in Oregon - Kettratad, Jes (Oregon State University, 2008)
"The goals of this study were: 1) to describe fishes in the genera Catostomus and Ptychocheilus in the Oregon Coastal Subprovince using morphological data and mitochondrial cytochrome b sequences; 2) to investigate the relationships of fishes in the Oregon Coastal Subprovince to nearby provinces; and 3) to address competing distribution theories." (from the Abstract) The author proposes that, based on the endemic distribution of freshwater fishes, the Oregon coast may deserve designation as a biogeographic subprovince, ranging from the Miami River in the north to the Sixes River in the south. Possible explanations for the distribution of these fishes are considered. The major professor was Douglas Markle.

Small Dam Removal in Oregon: A Guide for Project Managers - Hoffert-Hay, Denise; Oregon Watershed Enhancement Board, (Oregon Watershed Enhancement Board, 2008)
“As a result of changing technology and values, many small dams in Oregon have out-lived their original purpose due to changes in Oregon’s economic and resource landscape. These relic dams that have out-lived their useful lives are good candidates for removal. The financial burden of maintaining an aging structure can far outweigh the benefits of keeping it” (p.1).

Status of winter rearing habitat in four coho population units, 2007 - Romer, Jeremy D.; Anlauf, Kara Janaye.; Jones, Kim K.; Oregon. Dept. of Fish and Wildlife,; Oregon Plan for Salmon and Watersheds, (Monitoring Program Report (Oregon Plan for Salmon and Watersheds), 2008)
Winter surveys of Nehalem, Siuslaw, Coquille and South Umpqua Rivers to assess habitat, describe differences between winter and summer habitat, locate possible future survey sites and evaluate utility of winter habitat surveys. Habitat is most limiting to coho survival in the winter, thus winter surveys are more useful. The model used predicted that the Nehalem and Siuslaw basins could support the highest density of juvenile coho, and the South Umpqua the least.

Effects of Wildfire on Growth and Demographics of Coastal Cutthroat Trout in Headwater Streams - Heck, Michael P. (Oregon State University, 2007)
Studied effects of the Apple Fire of August, 2002 on cutthroat trout populations in the North Umpqua River Basin. Cavitt Creek was the unburned control. Used fish scale growth rings to determine growth and metabolism. Water temperatures in the burned streams rose following the fire. Interestingly, trout grew more following the burn. "Despite extensive changes to the physical environment following the wildfire, fish responded to these new conditions and were resilient to disturbance over short time scales. In fact, low pre-fire water temperatures may have been a limiting factor in these streams and only following increases in water temperatures were fish able to exhibit elevated growth rates and achieve greater sizes."

Juvenile coho salmon growth and survival across stream network seasonal habitats - Ebersole, Joseph L.; Wigington, Jr., Parker J.; Baker, Joan P.; Cairns, Michael A.; Church, M. Robbins; Hansen, Bruce P.; Miller, Bruce A.; Lavigne, Henry R.; Compton, Jana E.; Leibowitz, Scott G. (Transactions of the American Fisheries Society, 2006)
Juvenile coho salmon were tagged and monitored to assess relationship of smolt size to survival, and to evaluate different habitats. Fish were highly mobile during overwintering period. Spatial variability, more gravel (less bedrock), larger spring smolt size, availability of small tributaries when main-stem habitat has been degraded all contribute to productivity. Stresses importance of connections between streams.
