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...

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...

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...

Comprehensive multiyear carbon budget of a temperate headwater stream

Creator:: Argerich, Alba, Haggerty, Roy, Johnson, Sherri L., Wondzell, Steven M., Dosch, Nicholas, Corson-Rikert, Hayley, Ashkenas, Linda R., Pennington, Robert, and Thomas, Christoph K.
Abstract:: Headwater streams comprise nearly 90% of the total length of perennial channels in global catchments. They mineralize organic carbon entering from terrestrial systems, evade terrestrial carbon dioxide (CO₂ ), and generate and remove carbon through in-stream primary production and respiration. Despite their importance, headwater streams are often neglected in global...

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...

Creator:: Lockhart, Brian Roy, Ezell, Andrew W., and Hodges, John D.
Abstract:: Continuing education workshops and shortcourses are playing an increasingly important role in the education of forest resource professionals. The “tug-of-war” between breadth and depth in undergraduate curricula, combined with pressure to reduce the number of credit hours required for graduation, create knowledge gaps in various disciplines. Workshops and shortcourses help...

The value of recurring intradisciplinary meetings for preventing stagnation in natural resources education

Creator:: Loewenstein, Edward F., Lockhart, Brian Roy, Long, James N., and Ezell, Andrew W.
Abstract:: Most of the forces in academia work to develop highly specialized individuals. Training comes primarily from a single person, the dissertation advisor. Detailed field study of various forest types or physiographic provinces is often limited to where we trained and where we work (sometime both are in the same location...

Opportunities and limitations in teaching forest resource continuing education : experiences with southern bottomland hardwood workshops and shortcourses (an update)

Quantifying spatial differences in metabolism in headwater streams

Creator:: Gonzalez-Pinzon, Ricardo, Haggerty, Roy, and Argerich, Alba
Abstract:: Stream functioning includes simultaneous interaction among solute transport, nutrient processing, and metabolism. Metabolism is measured with methods that have limited spatial representativeness and are highly uncertain. These problems restrict development of methods for up-scaling biological processes that mediate nutrient processing. We used the resazurin–resorufin (Raz-Rru) tracer system to estimate metabolism...
