Catchment-Scale Modeling of Nitrogen Dynamics in a Temperate Forested Watershed, Oregon. An Interdisciplinary Communication Strategy

Creator:: Vaché, Kellie, Breuer, Lutz, Jones, Julia A., and Sollins, Phil
Abstract:: We present a systems modeling approach to the development of a place-based ecohydrological model. The conceptual model is calibrated to a variety of existing observations, taken in watershed 10 (WS10) at the HJ Andrews Experimental Forest (HJA) in Oregon, USA, a long term ecological research (LTER) site with a long...

A Note on the Sensitivity of A Closed-Tube Bioassay To Volatile Methylisothiocyanate Residues In Fumigant-Treated Wood

Creator:: Zahora, Andrew R. and Morrell, Jeffrey J.
Abstract:: A closed-tube bioassay with Poria placenta was used to measure residual fungistatic vapors in wood fumigated with methylisothiocyanate (MIT). This bioassay showed an inverse linear relationship between fungal growth and the amount of MIT in the wood samples. For fumigated increment-core sections of unseasoned Douglas-fir heartwood (4.8 mm in diameter...

The influence of wood moisture content on the fungitoxicity of methylisothiocyanate in Douglas-fir heartwood

Creator:: Zahora, Andrew R. and Morrell, Jeffrey J.
Abstract:: High concentrations of the fumigant methylisothiocyanate (MITC) will effectively control decay fungi in large wood structures, but the fungitoxicity of low MITC concentrations and the influence of wood moisture content (MC) on its performance are not well understood. The MC of Douglas-fir heartwood greatly influenced the susceptibility of the decay...

Diffusion and sorption of the fumigant methylisothiocyanate in Douglas-fir wood

Creator:: Zahora, Andrew R. and Morrell, Jeffrey J.
Abstract:: The influence of moisture content (MC) and conventional preservative treatment on methylisothiocyanate (MIT) sorption and diffusion were investigated in Douglas-fir wood. In wood at 0% MC, the ratio of equilibrium MIT adsorption to desorption concentrations was low (0.2), but it increased rapidly to about 0.94 above 18% MC. Partition coefficients...

Remote sensing of transpiration and heat fluxes using multi-angle observations

Creator:: Hilker, Thomas, Hall, Forrest G., Coops, Nicholas C., Collatz, James G., Black, T. Andrew, Tucker, Compton J., Sellers, Piers J., and Grant, Nicholas
Abstract:: Surface energy balance is a major determinant of land surface temperature and the Earth's climate. To date, there is no approach that can produce effective, physically consistent, global and multi-decadal energy–water flux data over land. Net radiation (R[subscript n]) can be quantified regionally using satellite retrievals of surface reflectance and...

Canopy gaps affect long-term patterns of tree growth and mortality in mature and old-growth forests in the Pacific Northwest

Creator:: Gray, Andrew N., Spies, Thomas A., and Pabst, Robert J.
Abstract:: Canopy gaps created by tree mortality can affect the speed and trajectory of vegetation growth, species’ population dynamics, and spatial heterogeneity in mature forests. Most studies focus on plant development within gaps, yet gaps also affect the mortality and growth of surrounding trees, which influence shading and root encroachment into...

Reduction in carbon uptake during turn of the century drought in western North America

Creator:: Schwalm, Christopher R., Williams, Christopher A., Schaefer, Kevin, Baldocchi, Dennis D., Black, T. Andrew, Goldstein, Allen H., Law, Beverly E., Oechel, Walter C., Paw U, Kyaw Tha, and Scott, Russel L.
Abstract:: Fossil fuel emissions aside, temperate North America is a net sink of carbon dioxide at present¹⁻³. Year-to-year variations in this carbon sink are linked to variations in hydroclimate that affect net ecosystem productivity³,⁴. The severity and incidence of climatic extremes, including drought, have increased as a result of climate warming⁵⁻⁸....

Truth to Nature: The Art and Ecology of Hudson River School Painting

Creator:: Loeb, Harper
Abstract:: Beginning with the inception of American art history as a formal discipline in the 1940s, the dominant mode of interpreting nineteenth-century American landscape painting has been to view aspects of the landscape as symbols for grand cultural, religious, national, and moral narratives. While this method of interpretation highlights some key...

Diversity and productivity of hypogeous fungal sporocarps in a variably thinned Douglas-fir forest

Creator:: Colgan, Wesley, Carey, Andrew B., Trappe, James M., Molina, Randy, and Thysell, David
Abstract:: Although ecosystem management techniques are designed to enhance species diversity in managed forests, no comprehensive study has been conducted to evaluate effects of such techniques on diversity and productivity of hypogeous fungi (truffles). During this study, truffles were collected in a 55- to 65-year-old Douglas-fir forest from March 1993 through...
