The Vadose Zone as a Hyporheic Carbon Source : A Look at Temporal Trends in Hyporheic Zone pCO₂

Creator:: Brandes, Jason B.
Abstract:: Stream chemistry studies conducted in the forested Watershed 1 of the HJ Andrews Experimental Forest show a contribution of CO2 from the hyporheic zone. Hyporheic CO₂ concentrations, measured as pCO₂, have a seasonal trend as well as a responsiveness to storm events. Concentrations are highest at the end of the...

Measurement of Gas Exchange, Stream Metabolism, and Carbon Fluxes of Headwater Streams

Creator:: Pennington, Robert S.
Abstract:: Freshwater systems are an important component of the global carbon cycle as they outgas disproportionately large quantities of carbon compared to the terrestrial landscape. Of particular importance are headwater streams, which represent roughly 90% of the channel network by length and have been conservatively estimated to outgas roughly 36% of...

Evidence of buried particulate organic carbon as foundation for heterotrophic carbon metabolism in the hyporheic zone of a montane headwater stream in the H. J. Andrews Experimental Forest, Oregon, USA

Creator:: Serchan, Satish P.
Abstract:: Streams and rivers play a critical role in global carbon (C) cycling by processing, storing, and transporting C. Headwater streams which make up more than 95% of the length of streams and rivers worldwide have disproportionate influence on fluvial C dynamics. The hyporheic zone (HZ) of headwater streams is a...

Geomorphic and Climatic Controls on Water Temperature and Streambed Scour, Copper River Delta, Alaska : Implications for Understanding Climate Change Impacts to the Pacific Salmon Egg Incubation Environment

Creator:: Adelfio, Luca A.
Abstract:: Pacific salmon (Oncorhynchus spp.) face numerous challenges associated with climate change. Most research has emphasized the potential effects of elevated summer water temperatures; however, climatic changes are also projected to significantly alter incubation and rearing habitats during the late autumn, winter, and spring months ("the incubation period"). Along the southern...

Long-term Ecohydrologic Response to Western Juniper (Juniperus occidentalis) Control in Semiarid Watersheds of Central Oregon : A Paired Watershed Study

Creator:: Ray, Grace L.
Abstract:: Rangelands span over 50% of the globe and approximately 70% of the United States. Although livestock production is an important use of rangelands, the benefits of rangelands are highly diverse. Humans find intrinsic value in protecting these unique and variable landscapes for wildlife, vegetation, and recreation enthusiasts. Woodland plant encroachment...

A Contingency-Based Evaluation for Beaver Restoration of Salmon Habitat in Oregon Coastal Streams

Creator:: Stevenson, John R.
Abstract:: Streams across the western United States are impaired from human alterations that have reduced freshwater habitat by simplifying channel complexity and disconnecting floodplains (Knox et al., 2022; Waples et al., 2008; Wohl, 2014). Climate change is likely to continue exacerbating these risks by warming summer surface stream temperatures (Crozier et...

Spatial Patterns of Soil Moisture and the Relative Importance of Atmospheric Water Demand Versus Soil Moisture Availability in Limiting Late-summer Growth of Douglas-fir Under a Changing Climate

Creator:: Jarecke, Karla M.
Abstract:: The rapid pace of climate change is increasing tree mortality and highlighting the need to improve the mechanistic understanding of plant function under increased water stress. However, the processes that control soil moisture availability in steep mountainous terrain are poorly understood, as are the relative effects of atmospheric and soil...

Carbon dynamics in the hyporheic zone of a headwater mountain stream in the Cascade Mountains, Oregon

Creator:: Corson-Rikert, Hayley A.
Abstract:: This study investigated carbon dynamics in the hyporheic zone of a steep, forested catchment in the Cascade Mountains of western Oregon, USA. Water samples were collected monthly from a headwater stream and well network during baseflow conditions from July to December 2013 and again in March 2014. We also sampled...

Influences of Thermal and Trophic Heterogeneity on Phenology, Growth, and Resource Use by Juvenile Coho Salmon

Creator:: Campbell, Emily Y.
Abstract:: Ecological resources available to freshwater fish shift spatially, temporally and across life stages. To better understand how spatial-temporal availability of resources influence fish, I examined the phenologies of hatching and emergence of Coho Salmon (Oncorhynchus kisutch) in streams with contrasting and strongly defined seasonal thermal variability. The study streams included...

Hydro-biogeochemical coupling at the hillslope and catchment scale

Creator:: van Verseveld, Willem J.
Abstract:: The specific objectives of this dissertation are to determine subsurface flow behaviors across different antecedent wetness conditions from a top-down perspective and to mechanistically assess the hydrological controls on DOC and N transport at the hillslope and catchment scale. The study area is a small catchment where hillslopes issue directly...
