Headwater stream characterization : an energy and physical approach to stream temperature using distributed temperature sensing

Creator:: Roth, Travis R.
Abstract:: Headwater streams are an integral part of the ecological health of the greater stream network as they provide valuable biological habitat, provide upwards to 95% of total in channel flow, while providing downstream reaches with important constituents such as sediment and woody debris. Small headwater streams are particularly susceptible to...

Variation in air and soil temperatures in forest communities on the H. J. Andrews Experimental Forest, 1970-1972

Creator:: Zobel, Donald B., McKee, Arthur, Hawk, Glenn M., Dyrness, C. T., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: Air temperatures at i m and soil temperatures at 2C cm are reported for twenty-one forest stands in the central Western Cascader of Oregon. Records began in 1970 for some stands, in 1971 or 1972 for most. Temperature Growth Index for a stand, based on temperature effects on Douglas-fir seedling...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

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...

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...

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;...

Variation in plant moisture stress associated with forest communities in the H. J. Andrews Experimental Forest

Creator:: Zobel, Donald B., Hawk, Glenn M., McKee, W. Arthur, Dyrness, C. T., and U. S. International Biological Program. Coniferous Forest Biome
Abstract:: Measurement of plant moisture stress of 1-2 m understory conifers was made in "reference stands" on the H. J. Andrews Experimental Forest in 1970-1972. Maximum stress each year (measured between midnight and dawn) is closely correlated with the position of each community along one axis of an ordination of the...

Modeling water uptake on coniferous forest Oregon watershed 10 synthesis

Creator:: Waring, Richard H., Running, S. W., Holbo, Harold Richard, Kline, J. R., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington
Abstract:: In the Coniferous Forest Biome, many of the understory as well as dominant plants are evergreen and thus water uptake is a year around process. The flow of water from the soil through plants to the atmosphere affects the entire forest ecosystem. As water is evaporated, it absorbs heat and...
