Inter-relationships of vegetation, hydrology and micro-climate in a young, Douglas-fir forest

Creator:: Barnard, Holly Rene
Abstract:: The links between forests, streamflow, and climate are poorly understood. Despite hundreds of studies over the past 60 years, fundamental questions of forests' effects on the hydrologic cycle remain unanswered. The hydrological cycle involves mutually-dependent biological and physical processes that operate at multiple scales of time and space, and this...

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...

Homogenization of Detrital Leachate in an Old-Growth Coniferous Forest, OR : DOC Fluorescence Signatures in Soils Undergoing Long-Term Litter Manipulations

Creator:: Strid, April R.
Abstract:: Soil dissolved organic carbon (DOC) is a small but crucial part of the forest carbon cycle. Characterizing the relationship between detrital inputs and soil DOC chemistry is crucial to understanding the ultimate fate of root carbon, fallen wood and needles. Chemical differences in the DOC pool may help to explain...

Terrestrial decomposition 1973 : a synopsis

Creator:: Fogel, Robert, Cromack, Kermit, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: This report describes decomposition studies conducted in the H. J. Andrews Forest, Oregon in 1973. Changes in weight loss and nutrient content of leaves, cones, branches, and bark of Douglas-fir and leaves of big-leaf maple, vine maple, Rhododendron, red alder, sword fern Oregon oak, and Chinkapin were recorded in a...

Spatiotemporal dynamics and drivers of stream pCO₂ in a headwater mountain catchment in the Cascade Mountains, Oregon

Creator:: Dosch, Nicholas T.
Abstract:: We examined the spatial and temporal variability of stream carbon dioxide (CO₂) and the drivers of these variations in a headwater catchment. To examine temporal variation and drivers, we measured stream and hyporheic pCO₂ at high temporal resolution over 11 months in a 95.9-ha forested headwater catchment in the Western...

Reactive polyphenols and dissolved nutrients in a nitrogen-limited headwater catchment, western Cascades, Oregon, USA

Creator:: Rasmussen, Janet K.
Abstract:: In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...

Patterns of nitrogen fluxes in watersheds of the H.J. Andrews Experimental Forest, OR

Creator:: Vanderbilt, Kristin Lynn, 1967-
Abstract:: Seasonal and annual patterns of N fluxes and concentrations in streamwater in six conifer-dominated watersheds at the H.J. Andrews Experimental Forest, OR, were studied to gain insight into the factors that influence N retention in this ecosystem. Processes affecting N flux in streamwater differed between organic (DON) and inorganic (DIN;...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Effect of adult aquatic insect life history on return to Lookout Creek, H. J. Andrews Experimental Forest, Oregon

Creator:: Farrand, Alexander Mark
Abstract:: Aquatic insects that emerge out of streams to mate represent a potential energy flux to terrestrial food webs. The relative success of an individual aquatic adult insect is whether it survives long enough to produce offspring, i.e. mate and return to the stream to oviposit eggs. Some characteristics of the...

Nitrogen and phosphorus dynamics during decomposition of multiple litter types in temperate coniferous forests

Creator:: van Huysen, Tiffany L.
Abstract:: Litter nutrient dynamics contribute significantly to biogeochemical cycling in forest ecosystems. These dynamics may be influenced by site attributes, litter nutrient concentrations, and soil nutrient availability either independently or synergistically. Litter nutrient dynamics were examined in two decomposition studies in temperate coniferous forests of Oregon. I used ¹⁵N-labelled litter of...
